King, Pamela Kay. "Adolescent Sexual Behavior and Identity Development". DigitalCommons@USU, 1993. https://digitalcommons.usu.edu/etd/2402.
Testo completoAbstract (sommario):
The purpose of this study was to determine if there is a relationship between adolescent sexual behavior, motivations, and identity status. A review of the literature indicated that deviant behaviors covary, and that drug use and abuse and the motivations for same are related to identity status .
A questionnaire, including the Extended Objective Measure of Ego Identity Status(EOM-EIS) and a series of questions to gather information about sexual behaviors and motivations, was employed. The sample consisted of 579 university students ranging in age from 17 to 25.
The dependent variable (sexual behavior and motivation) was viewed through the categorical assignments of identity status achieved, moratorium, foreclosed, and diffused, as well as through individual scores. As anticipated there was a relationship between sexual behavior and identity status; specifically, risky sexual behavior was positively correlated with identity diffusion, and abstinence with identity foreclosure. Adolescents in all statuses were equally consistent users of contraception, not just identity achieved as hypothesized. There was not a clear response pattern mediated by identity status as initially anticipated. Implications were discussed.

Testo completoAbstract (sommario):
This review of sexual education in the United States broadly defines the two most common approaches in sexual education seen in this country today. I cover the status of certain sexual behaviors and risks amongst the teenage population in the U.S. and specifically cover reported sexual activity in high school students and overall data on teen pregnancies and sexually transmitted infections (STIs). This work specifically looks at Maine, California, Texas, Maryland, North Carolina, and New Mexico to highlight the variety of state policies concerning sexual education and the differences in teenage sexual behaviors that exist within each of those six states. A description of how cultural influences can affect a young person’s sexual behavior is also given. In the final discussion section of this paper I have emphasized the need for more comprehensive sexual education programs in the United States and the importance of providing culturally sensitive programs in order to continue the fight against teenage pregnancy and STI rates in adolescents.

Sunday, Kelly L. "Adolescents with Problem Sexual Behavior". Thesis, Southern Connecticut State University, 2017. http://pqdtopen.proquest.com/#viewpdf?dispub=10189387.
Testo completoAbstract (sommario):
Previous research has found that adolescents with problem sexual behavior (PSB) are a heterogeneous population, exhibiting a wide range of behaviors from noncontact offenses to penetrative acts. Perpetrators differ in levels of aggression and violence, and in both the gender and age of their victims. However, it has been found that there are certain biopsychosocial factors contributing to the likelihood that an adolescent will engage in PSB. The purpose of this literature review is to compile a comprehensive overview of these common characteristics of adolescents with PSB. Knowing the risk factors for PSB may help guide those in the mental health field to better understand adolescents who sexually offend, and choose appropriate treatment options for these offenders.

Loew, Nicole Mary. "Perspectives of responsible sexual behavior". Diss., University of Iowa, 2017. https://ir.uiowa.edu/etd/5554.
Testo completoAbstract (sommario):
The concept of responsible sexual behavior (RSB) gained popularity when it was introduced in Healthy People 2010 as a leading health indicator. The Healthy People initiatives organize the top health priorities and create guidelines for improving the health of Americans. Promoting RSB was intended to address problems such as unintended pregnancy and sexually transmitted infections (STIs), however the guidelines never conceptually define behavior that would be considered sexually responsible. Thus, the purpose of this dissertation research was to examine how responsible sexual behavior (RSB) was defined in the context of public health literature, collegiate women, and rural women with the intention to contribute to a clearer conceptual understanding of RSB.
First, an evolutionary concept analysis was conducted to define the attributes of RSB and develop a conceptual definition of responsible sexual behavior (RSB) as it applies to women 18 years and older who have sex with men from a synthesis of lay and public health literature. According to the literature, RSB is a desirable and deliberative pattern of behaviors that promote sexual health, manage risk, and foster respect of sexual partners within the context of community influences. This study also concludes that a purposeful redefinition maybe necessary to maintain a concept that is useful for guiding and evaluating sexual behavior.
Second, a secondary data analysis was completed to identify college women definition of “sexual responsibility.” Data came from interviews collected as part of a mixed methods study of college women and unintended pregnancy. A total of 35 interviews were analyzed using within and across case methodology to derive a working definition of RSB for collegiate women. Women in this sample described being sexually responsible as self-advocating through actions that were consistent with personal goals and values while being aware of consequences that could threaten those goals or values. Actions included mindful partner selection, communicating boundaries, and preventing pregnancy. Women’s academic goals were closely linked to women’s sexual health decision making.
Third, an exploratory descriptive study was completed to identify how rural women who have sex with men define RSB and to understand the role of the rural context on definitions and enactment of RSB. A total of ten rural Iowa women aged 18-29 participated in phone interviews. Within and across case analysis was used to describe the contextual influences of how rural dwelling women defined and enacted responsible sexual behavior. For rural women in this sample, RSB is understanding the consequences of sex and taking action to manage risks by preventing pregnancy and STIs, mindfully selecting of partners, and seeking appropriate resources. The social context of the rural environment acted as both a facilitator and barrier for women to acquire information enact RSB.
In conclusion, RSB was an accessible concept for college and rural women to define and understand. However, the collective research indicated that a new definition of RSB was necessary to maintain its purpose in improving sexual and reproductive health. Thus, being sexually responsible is having an awareness of consequences and managing risks in a way that is reflective of a woman’s personal experiences, beliefs, values, and goals. How BSR is defined is fluid and subject to redefinition based on personal experiences and movement through the lifespan. Future research should focus on understanding how other populations of women define and manage BSR and that public health interventions and policy support women’s ability to be sexually responsible.

Christopherson, Cynthia R. "Pubertal Development, Parent-Teen Communication, and Sexual Values as Predictors of Adolescent Sexual Intentions and Sexually Related Behaviors". DigitalCommons@USU, 1993. https://digitalcommons.usu.edu/etd/2393.
Testo completoAbstract (sommario):
Adolescent sexual intercourse can be viewed as a normal developmental experience, but intercourse also is linked to unplanned pregnancies, Sexually Transmitted Diseases (STDs). and Acquired Immune Deficiency Syndrome (AIDS). Consequently, there continues to be a high level of scientific interest in understanding antecedents of adolescent sexual behavior, especially early and more risky sexual intercourse. This study examined several key antecedents of adolescent sexual intentions and behavior, including pubertal development (pubertal status, change over time, and pubertal timing). parent/teen communication, and teen sexual values. Analyses were based on longitudinal data collected in 1991, 1992, and 1993 from parents and teens during the FACTS & feelings project conducted within three areas in northern Utah.
Regression and path analyses were used to test the direct and indirect effects among the variables. Parent/teen communication quality had a significant positive effect on teen sexual abstinent values for both males and females. Sexual abstinent values had a strong negative effect on sexual intentions for both males and females. Sexual values were more strongly related to sexual behavior for females than for males. Sexual intentions had a significant effect on sexual behaviors for both males and females, although this effect was stronger for males than for females. Pubertal timing had a significant effect on behaviors for males and a smaller although significant effect for females Age also had a significant positive effect for both male and female adolescents. Overall, within these analyses, females were more influenced by values which directly and indirectly affect sexual behaviors. Males were more influenced by the FACTS & feelings treatment, pubertal timing, and sexual intentions.

Christensen, Mathew. "Forced Sexual Intercourse in Relation to Female Adolescents' Risky Sexual Behavior, Psychopathology, and Behavior Problems". DigitalCommons@USU, 1999. https://digitalcommons.usu.edu/etd/2459.
Testo completoAbstract (sommario):
During 1995, over 20,000 adolescents completed the in-home interview for The National Longitudinal Study of Adolescent Health (Add Health). One question asked females if they had ever been forced to have sexual intercourse (FSI). In addition, they were asked about other sexual behavior, their psychological well-being, and behavior problems. The present study examines the associations between FSI and 26 outcome variables, comparing adolescent females who reported FSI with females who reported voluntary intercourse, and with females who reported no intercourse. In addition, the large Add Health sample allowed comparisons between five race/ethnicity groups and four adolescent groups broken down by age.
Psychological and emotional correlates of sexual abuse have been widely documented, but until now, studies of sexual abuse had largely consisted of small samples of mostly White females with limited generalizability. The Add Health sample was large enough to go beyond psychopathology to include risky sexual behavior, and behavior problems. The Add Health sample is representative of the overall population of adolescents in the United States during the mid 1990s.
Results showed that females forced to have intercourse have earlier and more frequent risky sexual behavior, more severe symptoms of psychopathology, and were much more likely to report behavior problems such as smoking, drinking, and drug use (a finding that has been largely unreported) than were females who reported no intercourse. Drug use was the variable on which females who reported forced intercourse and those who reported no intercourse differed most. Females who reported FSI were five times more likely to have reported illicit drug use than were females who reported no intercourse. Asian and White females who reported forced intercourse had the greatest vulnerability for negative outcomes, while African American females who reported forced intercourse had the greatest resilience against negative outcomes. Among female adolescents who reported forced intercourse, the youngest (ages 12, 13, and 14 years) were the most vulnerable to experience severe psychopathology and to report cigarette smoking and drinking alcohol.

Testo completoAbstract (sommario):
Após o sucesso de vendas do Viagra, medicamento indicado para o tratamento da disfunção erétil, lançado em 1998, houve uma rápida proliferação de artigos, livros e encontros sobre as disfunções sexuais femininas. Desde 2000, um intenso debate sobre o envolvimento da indústria farmacêutica na produção biomédica sobre as disfunções sexuais femininas e a concomitante busca por um medicamento similar ao Viagra destinado às mulheres tem envolvido profissionais de diferentes disciplinas. Esta dissertação teve como objetivo investigar os discursos científicos sobre as disfunções sexuais femininas, através do exame dos artigos publicados no periódico Archives of Sexual Behavior, desde sua fundação, em 1971, até 2007. O periódico foi escolhido por sua legitimidade neste campo de saberes, por abranger um amplo período (36 anos) e seu caráter multidisciplinar. Pretendeu-se investigar quando, como e por quais grupos profissionais as disfunções sexuais femininas foram descritas e abordadas no periódico. No caso das chamadas disfunções sexuais, as descrições científicas, que vêm aumentando significativamente nos últimos anos, dão origem
a prescrições de terapias, medicamentos, intervenções cirúrgicas, programas de educação sexual e políticas públicas. Ou seja, subjacente a esse discurso, que afirma ser empírico e
imparcial, estão processos que se encontram muito além dos limites de um laboratório ou das atividades de um pesquisador. Buscou-se, assim, pensar a produção científica como produto
de articulações e negociações que se desenrolam em esferas diversas, envolvendo processos culturais, sociais, econômicos e também cognitivos ou científicos, em contraposição às
concepções que caracterizam a ciência como um projeto que apenas revela verdades. Para tanto, foi apresentado o contexto do surgimento de uma ciência da sexualidade, no decorrer do século XIX e, em seguida, o contexto no qual emergiram os discursos sobre as disfunções sexuais femininas, o que propiciou sua emergência naquele dado momento, o modo como foram definidas e por quem, como se articularam a processos sociais, econômicos e culturais e que transformações sofreram ao longo dos anos.After the sale success of Viagra, a medicament indicated for the treatment of erectile dysfunction, which was launched in 1998, there was a fast proliferation of articles, books and meetings on female sexual dysfunctions. Since 2000, an intense debate about the involvement of the pharmaceutical industry in the biomedical production related to female sexual dysfunctions and the simultaneous search for a medicament similar to Viagra aimed to women has been involving professional from different areas. The goal of this dissertation was to investigate scientific discourses on female sexual dysfunctions through the analysis of articles published in the periodical Archives of Sexual Behavior, since its foundation in 1971 until 2007. The periodical was chosen due to its legitimacy in this field of knowledge, for covering a vast period (36 years) and for its multidisciplinary nature. The intention was to locate when, how and by which professional groups female sexual dysfunctions were described and dealt with in the periodical. In the case of the so-called sexual dysfunctions, scientific descriptions, which have been significantly increasing in recent years, originate therapeutic prescriptions, medicaments, chirurgical interventions, sexual education programs and public policies. That is, subjacent to this discourse, which poses as empirical and impartial processes were found that reach quite beyond the limits of a lab or the activities of a researcher. Therefore, the aim was to think of the scientific production as a product of articulations and negotiations unfolded in diversified domains and involving cultural, social and economical processes, as well as cognitive and scientific ones, in contrast to the conceptions that characterize science as a project that only brings about the truth. For this, the context in which a science of sexuality emerged throughout the 19th Century was presented, followed by the context in which the discourses on female sexual dysfunctions appeared: what has facilitated their emergence in that given moment, how and by whom were they defined, how were they articulated to social, economical and cultural processes and which transformations they suffered throughout the years.

This dissertation examines the relationship between same-sex sexual behavior and Age, Period, and Birth Cohort through an analysis of the General Social Survey (GSS). The GSS has undertaken 14 rounds of data collection between 1988 and 2010 in which questions on sexual behavior have been administered (n=33,212, 14,591 Males, 18,621 Females). Logistic regression models were employed in order to parse out the effects of Age, Period, and Birth Cohort, along with other explanatory variables, to determine the likelihood of the reporting same-sex sexual behavior. It was found that among women, but not men, there is a significant birth cohort effect on same-sex sexual behavior. Among, men, but not women, there was significant period effect on same-sex sexual behavior in Time 3 of the study. Among both men and women, there was a significant curvilinear relationship between age and the reporting of same-sex sexual behavior. Shifts in cultural values and methodological issues may explain the birth cohort and period effects on same-sex sexual behavior. The idea of the "sexual narrative" is introduced to explain the curvilinear age effect on same-sex sexual behavior.10000-01-01

Testo completoAbstract (sommario):
Examined within this study were the relations between two processes within sexual identity development, sexual identity exploration and sexual identity commitment, and risky sexual behaviors. The moderating effects of sexual identity commitment, sexual self-efficacy, and positive condom use attitudes on relations between sexual identity exploration and risky sexual behaviors were also examined. Risky sexual behaviors included the frequency of substance prior to and barrier protection use during sex, multiple sex partners, and the initiation of sex prior to age sixteen. Study participants included 322 college students attending an urban university in the Southeastern United States. All were heterosexual and reported engaging in vaginal, anal or oral sex in the past 30 days. A high percentage of study participants reported at least one risky sexual behavior in the past 30 days, and most reported not using barrier protection during anal and oral sex. No direct effects were found between sexual identity exploration and any risky sexual behavior. Only one direct effect was found between higher levels of sexual identity commitment and lower frequencies of barrier protection use for oral sex. No moderating effects were found for sexual identity commitment, sexual self-efficacy, or positive condom use attitudes on relations between sexual identity exploration and any risky sexual behavior. The findings highlight the importance of examining how to get emerging adults to consistently use barrier protection during any type of sexual behavior. The results also underscore the complexity of sexual risk-taking during emerging adulthood, and the need for continued examination of the ways in which processes associated with sexual identity development may impact sexual risk-taking during emerging adulthood.

Testo completoAbstract (sommario):
The prevalence of nonmarital sexual behavior among adolescents continues to rise, as does the number of sexually transmitted diseases, AIDS, and unwanted pregnancies. College-age adolescents appear to be even more susceptible to these problems. Sound theoretical knowledge would seem useful in designing more effective prevention programs. The purpose of this study was to identity theoretical factors that contribute to or decrease such behaviors.
Two hundred fifty-two single college students completed measures designed to examine relations among identity development, attachment patterns, gender, and sexual behavior in older adolescents. Attachment and identity measures were used to explore variations in sexual behavior relating to identity development and the quality of intimate relationships formed in late adolescence. Three measures were used to assess these theoretical constructs and to measure sexual behavior: The Personal Opinion Survey contains Grotevant and Adams' 64-item Extended Version of the Objective Measure ofEgo Identity Status; a modified version of Simpson, Rholes, and Nelligan's 13-item Attachment Style measure; and 19 items that assess sexual behaviors.
Results confirmed statistically significant relations among identity development, attachment patterns, gender, and sexual behavior. Specifically, correlational analyses confirmed relations among identity, attachment, and premarital intercourse, age of first intercourse, and items pertaining to risky sexual behavior. Identity was also statistically significantly related to premarital intercourse. Attachment and identity sub scale scores were predictive of sexual behavior when multiple regression equations were generated. Previous studies of identity, gender, and intimacy among older adolescents support the findings ofthis study. Other researchers have found relationships between attachment and intimacy among this population. The results of this study and future research areas are discussed.

Testo completoAbstract (sommario):
Adolescent fertility is a problem that is urgent in developing countries due to rapid population growth rates. To gain a better understanding of adolescent fertility within developing countries a study was undertaken to examine adolescent sexual behavior among teens within a developing country, Zambia. A self-administered questionnaire was given to secondary school going teenage women in Zambia. The sample population consisted of 503 women between the ages of 12 and 19. The survey was analyzed using both regression and univariate analysis of the data. The findings revealed that a high percentage of the teens have initiated sexual activity; yet few (4.2%) have ever used modern contraceptive methods. Suggestions were made for family planning programs that would involve both parents and their children.

Testo completoAbstract (sommario):
One hundred fifty-six adolescent respondents from the Virginia Mennonite Conference were surveyed regarding their perceived influences of their attitudes toward sexuality and the Mennonite Church's position on various sexual issues. The adolescents were more sure of their own beliefs about sexuality than they were about the church's position. The church was not perceived as a major source of influence on their attitudes when compared to friends, the media, and the family. A comparison of early and late adolescents did not reveal any significant difference in the amount of perceived influence of the church. The gender of the respondent was not found to differentiate significantly on any of the variables under investigation. The type of school the adolescent attended--either public or Mennonite--was related to a difference in the response to beliefs about premarital sex and pregnancy outside of marriage. Students at public schools held more accepting views on these issues.

Questionnaire responses of 214 college students at Virginia Polytechnic & State University regarding AIDS anxiety and how it affects sexual behavior were analyzed. Results indicated that women tend to have more AIDS anxiety than do men. Fifty-three percent of the male respondents reported their AIDS anxiety to be low/very low, and 15.7% reported high/very high, while 44.9% of the women responded low/very low, and 22.5% as being high/very high.
Both males and females reported an increase in the number of sexual encounters a month, however, the number of different partners has decreased when data from 1986 and 1988 were compared. In 1986, 36.9% of the males reported being sexually active 3+ times a month, while in 1988, 51.5% of the males were sexually active 3+ times a month. In 1986, 50.2% of the females reported being sexually active 3+ times a month, whi1e 56.6% of the females in 1988 indicated that frequency. In 1986, 36.2% of the males and 31.5% of the females responded that they had 3+ different partners while 22.9% of the males and 14.1% of the females responded this way in 1988.
Those who reported experiencing high anxiety concerning AIDS were less likely to use birth control than those who reported a low AIDS anxiety. Seventy-one percent of the respondents reported using some form of birth control, with 35.5% reporting the use of condoms.Master of Science

Ethnographic interviews with pregnant Mexican-American and Native-American adolescents and young adults from low-income households explored their knowledge about conception and contraception as well as their contraceptive and sexual behavior. The findings suggest that their unwanted pregnancies are not due to a lack of knowledge but rather are due to their heteronomous sexual behavior which results in infrequent contraceptive usage and thereby a risk of unwanted pregnancy.

Testo completoAbstract (sommario):
This study was designed to determine; (1) if adolescent self esteem is related to premarital sexual attitudes and intercourse behavior; (2) if religious affiliation and church attendance affect the relationship between adolescent self esteem and premarital sexual attitudes and behavior. Approximately 2400 adolescents residing in California, New Mexico, and Utah comprised the sample.
Adolescents who attended church services more often reported less sexually permissive attitudes and behavior than those who attended church less often. Similarly, Mormons' premarital sexual attitudes and behavior was more conservative than was the case for non-Mormon adolescents. Findings indicated that the nature of the relationship between permissiveness and self esteem did depend on cultural norms or contexts. In the most conservative normative contexts (among Mormons and frequent church attenders) there was a negative relationship between self esteem and sexual attitudes and sexual behavior; there was no significant relationship between self esteem and sexual attitudes and sexual behavior among the more moderate sample groups.

Testo completoAbstract (sommario):
Double standard effects in inferences about quality of parenting and adult sexual outcomes for children were investigated under five conditions of single-parent sexual behavior. The sample comprised six hundred married parents from three major metropolitan areas in Texas. Subjects were administered a scenario about a hypothetical single parent family. The scenario varied with respect to parent gender, child gender, and type of parental sexual activity (e.g., abstinence, limited affairs away from home, involvement with a live-in lover, frequent partners spending the night, and a control condition containing no sexual message). Subjects were asked to rate a parent from the scenario on quality of parenting and predict the adult sexual behavior of the child. Hypothesized double standard effects did not emerge. A double standard in judgments about sexually active single parents and parenting did appear. Main effects were found for child gender and sexual lifestyle of the parent (e.g., parents with boys rated less favorably than parents with girls; promiscuous fathers were rated lower than promiscuous mothers). Several interaction effects among parent gender, child gender, and sexual lifestyle condition were also found (e.g., promiscuous parents were rated lower as parents and seen as negatively influencing the child's sexual development). Recommendations for future research include refining the two scales used in this study; extending the study to include data from single parents; examining whether the judgments of sexually active single parents affect the quality and quantity of interactions others have with either the parent or child.

Roberts, Mary Kathryn. "Sexual orientation self-label, behavior, and preference: College students in Taiwan and the USA". Thesis, University of North Texas, 2002. https://digital.library.unt.edu/ark:/67531/metadc3218/.
Testo completoAbstract (sommario):
The relationships among self-labeled sexual orientation, sexual preferences, and sexual behaviors were examined in samples from Taiwan and the USA. Subsamples matched on gender, age, and marital status were created to reduce sexual orientation cell size discrepancies and demographic differences. Sexual orientation self-label, the Kinsey Scale of Sexual Orientation, and a modified version for preference were used to assess participants' sexual orientation, behavior, and preference, respectively. Additional measures included an adaptation of the Early Sexual Experiences Checklist, and the Hopkins Symptom Checklist for psychological distress.
For both Taiwan and USA subsamples, heterosexual participants reported significantly greater congruence between sexual orientation identity and preference than did nonheterosexual participants. A high proportion of the Taiwan sample were celibate, precluding analyses of congruence between sexual orientation identity and sexual behavior. Congruence between sexual behavior and preference in the USA sample was negatively correlated with psychological distress. In a cross-cultural comparison between the Taiwan and USA women (n = 176), the two samples reported similar congruence between sexual orientation identity and preference.
Exploratory analyses revealed that heterosexual participants' sexual orientation label was more “public, ” (more categories of people who knew the participants' sexual orientation), than was nonheterosexuals' in both Taiwan and the USA. In Taiwan, heterosexual and nonheterosexual participants reported similar proportions who were celibate. A gender difference within the USA subsample included that men reported significantly greater congruence than did women regarding sexual orientation identity and congruence between behavior and preference. Analyses comparing self-labeled sexual orientation groups on unwanted childhood sexual experiences and age of earliest voluntary sexual activity were not significant. This study's limitations included small numbers of bisexual (USA n = 27, Taiwan n = 17) or homosexual (USA n = 35, Taiwan n = 9) participants, prohibiting distinctions between them. Recommended future research includes examining the self-labeling process, Asian American student sexual behaviors, and incorporating frequency and intrusiveness when assessing unwanted childhood sexual experiences.

Testo completoAbstract (sommario):
Two studies tested whether reminders of safe sex and risky sex would lead to higher mortality salience, and if that higher mortality salience would lead men who have sex with men to be more sexually risky than men who have sex with women. In Study 1, both partner gender groups reported higher mortality salience after the risky sex and death primes, but not after the safe sex or the control primes. In Study 2, the men in both groups only reported higher mortality salience after the death primes. Partner gender moderated the effect of mortality salience primes on men’s willingness to engage in risky sexual behavior. Men who have sex with women reported greater willingness to engage in risky sexual behaviors than men who have sex with men after the death prime, and less willingness after the safe sex prime, compared to both the risky sex and control prime. Men who have sex with men did not report any differences in their willingness to engage in risky sexual behavior after any of the priming conditions. Estimates of peer engagement in risky sexual behavior correlated with both groups willingness to engage in risky sexual behavior, whereas self-esteem did not significantly correlate, moderate or mediate willingness to engage in risky sexual behavior in either group. Combining data from Study 1 and Study 2 found both groups reported higher mortality salience after the risky sex and death primes, but not after the safe sex or control primes. Implications for partner gender differences in responses to mortality salience as well as how to design safe-sex interventions are discussed.

The purpose of this study was to gain a better understanding of sexually aggressive behavior through the examination of humor appreciation among male undergraduates. As compared to nonaggressive males, sexually aggressive males showed a significantly greater appreciation for humor which negatively stereotyped females, portrayed prejudicial views of rape-and rape victims, and contained content related to male sex drive and virility. Differences in humor appreciation were also found for males with high sex drive. Additional findings included correlations between aggressive drive and sexually aggressive status, as well as between sex drive and likelihood to rape.

Thesis (MCur)--University of Stellenbosch, 2004.ENGLISH ABSTRACT: Research and in certain instances the lack of research as well as extensive experience of the researcher in this field of study convinced the researcher that a scientific study / exploration is critical on the different aspects of adolescent sexual health. A study, based on a combination of qualitative and quantitative methods (triangulation), was conducted to identify and describe the factors playing a role in adolescents’ experiencing problems in maintaining their sexual health. Adolescents are at risk of contracting Sexually Transmitted Diseases including HIV/AIDS because of their sexual behaviour. Initiation of early sexual relations contributing to possible multiple sexual partners and failure to consistently use condoms contribute to this risk. Failure to continuously use a reliable contraceptive method also enhances the risk of unintended pregnancies and consequent exposure to the risks involved in termination of pregnancy or the psychological effects of giving the baby up for adoption, the hardship of raising the baby as a single parent or being forced to marry at a young age. Thus the physical-, emotional-, and social well being of the adolescent is at risk when they are not equipped to maintain their sexual health.The study concludes that adolescents that are sexually active and have multiple sexual partners have a higher probability of not maintaining their sexual health. Based on the outcome of this study the researcher feels strongly that the following needs to be addressed in order to promote the maintenance of adolescent sexual health: • Professional nurses need to be trained and sensitized to guide and manage adolescents seeking sexual or reproductive advice; • Sexuality programmes need to be integrated into school curricula; • Positive use of the mass media to promote healthy lifestyles; and • Training programmes for parents and adolescents.
AFRIKAANSE OPSOMMING: Navorsing en in sekere gevalle die gebrek daaraan sowel as ekstensiewe ondervinding van die navorser in die studieveld, het die navorser oortuig dat ‘n wetenskaplike studie / eksplorasie oor die veskillende aspekte van adolessente seksuele gesondheid krities was. ‘n Studie, gebaseer op ‘n kombinasie van kwalitatiewe en kwantitatiewe metodes (triangulasie), was uitgevoer om die faktore wat ‘n rol speel in adolessente se vermoëns om hul seksuele gesondheid te handhaaf, te identifiseer en te bepreek. Adolessente se risiko is hoog om Seksueel Oordraagbare siektes, insluitend MIV/VIGS, op te doen weens hul seksuele gedrag. Die aanvang van vroeë seksuele verhoudings dra by tot moontlike meervoudige seksmaats en die gebrek aan konsekwente gebruik van kondome verhoog die risiko. Gebrek aan die aaneenlopende gebruik van ‘n betroubare kontraseptiewe metode verhoog ook die risiko van ‘n ongewensde swangerskap en gevolglike blootstelling aan die risiko’s verbonde aan terminasie van swangerskap of die psigologiese effekte wat gepaard gaan met aanneming, enkel ouerskap en geforseerde trou op ‘n vroeë ouderdom. Derhalwe word die fisiese-, emosionele- en sosiale welsyn van die adolessent bedreig as hulle nie toegerus is om hul seksuele gesondheid te handhaaf nie.Die gevolgtrekking van die studie is dat adolessente wat seksueel aktief is en meervoudige seksmaats het, ‘n hoër waarskynlikheid het om nie hul seksuele gesondheid te handhaaf nie. Gebaseer op die uitkoms van die studie is die navorser van mening dat die volgende aangespreek moet word ten einde die handhawing van adolessente seksuele gesondheid te bevorder: • Geregistreerde vepleegkundiges moet opgelei en gesensitiseer word om adolessente te hanteer en van leiding te voorsien; • Seksualitiet programme moet in die skool kurrikulum integreer word; • Positiewe gebruik van die massa media om gesonde lewenstyle te bevorder; en • Opleidingsprogramme vir ouers en adolessente.

Testo completoAbstract (sommario):
Five studies examined the possible influence of the sexual double standard on women's contraceptive behavior via sexual attitudes and social norms. In Study 1, longitudinal diary data from a community sample of 62 women showed that women's contraceptive behavior in ongoing sexual relationships was quadratically associated with sexual attitude. Study 2 showed that contraceptive behavior in initial and ongoing sexual encounters differed significantly in a sample of 52 university women. In initial encounters there was a greater reliance on condoms and a greater risk of unprotected intercourse. Studies 3, 4 and 5 used a person perception paradigm to examine women's perceptions of a female contraceptive provider in an initial sexual encounter. In Study 3, 57 women rated a female condom provider in a casual encounter as less nice, less socially acceptable, and her behavior as less appropriate than when her partner provided a condom. However, the target was rated as less wise if she had unprotected intercourse. In Study 4 (N = 249), a pill condition was added and the influence of sexual attitudes was assessed. Relative to when her partner provided a condom, women rated the target as less wise and less nice if she was on the pill, but they rated her as more wise when she provided a condom. Negative sexual attitudes were associated with more negative reactions but generally did not interact with contraceptive condition. In Study 5, 96 women rated the target as a function of who provided a condom (her vs. him) and four properties of the romantic relationship. Providing a condom did not result in negative evaluations in a committed relationship. In a non-committed relationship, when the woman provided a condom she was perceived as less nice but more wise. Furthermore, women used intimacy as a cue for commitment, but did not perceive intimacy alone as adequate justification for intercourse. The results of these five studies suggest that social norms may exist which discourag

The purpose of this study was to determine relationships between several educational variables and adolescents' sexual attitudes and behavior. The sample consisted of high school students who were enrolled in health, family living, and home economics classes in Salt Lake City, Utah, and Albuquerque, New Mexico. Pretest and posttest surveys were given to these students to evaluate the effectiveness of a prevention program which addressed teen attitudes and behaviors in the areas of peers, families, and morality . The pretest and posttest surveys contained items that specifically measured family background, school achievement, and sexual attitudes and behaviors. Data collected for these particular items were used in the analyses for this report. It was concluded that parental educational background was positively related to adolescents' educational aspirations and performance, and these educational variables were inversely related to adolescents' premarital sexual attitudes and behaviors.

Testo completoAbstract (sommario):
Adolescent pregnancy among students across South Africa is a growing concern. The high incidence of dropping out of school results in greatly diminished chances of success and independence for many. Sex education forms part of the life orientation curriculum, and it has been put in place by the Department of Education as a measure to reduce the prevalence of adolescent pregnancy. Parents of adolescents play a vital role in educating their children on sexual matters, secondary to that is community educations on sexual matters in aid of uplifting communities. The aim of the study was to explore the perception of how effective sex education could be a means of reducing pregnancies in the Blue Crane Route Municipality. To achieve this aim, three objectives and three research questions were articulated. The objectives were to explore the course content of life orientation provided to adolescents, to investigate by questioning adolescents concerning the importance of life orientation in their lives and to examine the factors responsible for the escalation of adolescent pregnancies in the municipality. The research questions were: How adequate was the course content of life orientation in helping adolescents in their sexual lives? How useful was life orientation to adolescent girls? What are the factors that increase the incidence of adolescent pregnancies in the municipality? Qualitative data was obtained through semi-structured interviews; focus group discussions were conducted with students, social workers and life orientation educators and observations made by them were recorded. Data was analysed thematically and was supported by relevant literature. The findings revealed that sex education is not effective in reducing pregnancies in the Blue Crane Route Municipality. The figures for adolescent pregnancy in schools have increased since 2007, when sex education was introduced as part of the life orientation curriculum. Accordingly, it is recommended that the Department of Education should re-evaluate the curriculum and appoint educators who are sufficiently trained in life orientation to make learners properly aware of the consequences of unwanted pregnancies.

Testo completoAbstract (sommario):
Only in recent years have diagnostic and therapeutic advances lengthened the life expectancy for patients who have cystic fibrosis sufficiently to allow some of them to live into adulthood. Health care professionals have been focusing on survival issues and are only recently beginning to look at quality of life issues, such as sexuality, of these patients. The purpose of the study was to create a sexual profile of adults with cystic fibrosis which would describe their sexuality and sexual concerns.
A questionnaire was developed and sent to all of the adult cystic fibrosis patients (19 years of age and older) in British Columbia (50 patients), all of whom attend the Shaughnessy Hospital Adult CF Clinic in Vancouver. The 62% response rate provided data for the sexual profile which indicated that 90% of the respondents were sexually active. Only a small number of subjects reported sexual difficulties in their relationships. Concerns about the impact of CF on their sexuality included: the effect of the potentially limited lifespan on their relationships, practical considerations such as fatigue and coughing during sexual activity, and poor body image.
A major issue for CF males is that most of them are infertile due to CF. How and when men should be told about this issue was an important question for the CF Clinic staff. Responses indicated that men thought they should find out from either the physician in the pediatric CF clinic or the physician in the adult CF clinic. Furthermore, 100% of the men suggested that this issue be discussed with males before the age of 19 years.
Limitations and recommendations of the research are discussed. A major recommendation is for physicians and other health care professionals in CF clinics to give patients the opportunity to discuss sexual issues.Education, Faculty of

INTRODUÇÃO: A despeito das graves consequências comportamentais de indivíduos que sofrem de impulso sexual excessivo (ISE), estudos neuropsicológicos são incipientes e trazem resultados controversos. OBJETIVOS: Por meio de um estudo experimental com sujeitos impulsivos sexuais (pacientes) e não impulsivos sexuais (controles) objetivou-se comparar: a tomada de decisão e a flexibilidade cognitiva no estado basal de vigília (tempo \"0\"); a tomada de decisão e flexibilidade cognitiva no tempo \"0\" e pós-estímulo sexual visual (tempo \"1\") em cada grupo (pacientes e controles) e entre os grupos. MÉTODO: O estudo foi desenvolvido no Ambulatório de ISE do Instituto de Psiquiatria (IPq) do HC-FMUSP. A amostra foi constituída por 30 pacientes e 30 controles recrutados através de divulgação na mídia. Homens, brasileiros, com 18 anos ou mais, que preencheram os critérios diagnósticos para ISE (CID-10 - F 52.7) e os critérios de Goodman para dependência de sexo foram incluídos como pacientes; enquanto participantes assintomáticos e que não preencheram os critérios acima foram incluídos como controles. A investigação neuropsicológica da flexibilidade cognitiva se deu por meio da aplicação Wisconsin Card Sort Test (WCST), enquanto a avaliação da tomada de decisão se deu pela aplicação do Iowa Gambling Task (IGT) no tempo \"0\" e tempo \"1\" (após visualização de vídeo erótico por 20 minutos), respeitando um intervalo mínimo de seis meses entre os tempos. Em ambos os tempos foi aplicada a Escala de Compulsividade Sexual, e no tempo \"1\" foi aplicado o Inventário do Desejo e da Excitação Sexual. RESULTADOS: No estado basal, os pacientes apresentaram maior quantidade de respostas corretas, em relação aos controles, no teste que investiga flexibilidade cognitiva (p = 0,01). Quando comparamos o desempenho de ambos os grupos com eles mesmos entre os tempos, observamos que os controles apresentaram melhor desempenho inicial (Bloco 1) na tomada de decisão (p = 0,01), bem como apresentaram mais acertos no teste que avalia flexibilidade cognitiva (p = 0,01) no tempo \"1\". O mesmo não foi observado em relação aos pacientes. Quando comparamos as médias da diferença (tempo \"1\" - tempo \"0\"), entre os grupos, observamos também melhor desempenho dos controles em relação à quantidade de acertos (p = 0,02). CONCLUSÕES: Desde onde sabemos, este é o primeiro estudo avaliando funções executivas em impulsivos sexuais, após exposição a estímulo visual sexual. Quanto à avaliação no estado basal, os pacientes apresentaram melhores resultados na flexibilidade cognitiva, contrariando a hipótese inicial. Controles apresentaram melhores desempenhos na flexibilidade cognitiva e tomada de decisão inicial após exposição ao estímulo visual sexual, quando comparados com os resultados no estado basal. Na análise da diferença de desempenho pós-estímulo visual sexual comparado com o estado basal, entre os grupos, os controles novamente apresentaram melhor desempenho cognitivo. Tais resultados indicam escolhas iniciais menos impulsivas, e melhor flexibilidade cognitiva, após exposição ao estímulo erótico, pelos controles, sugerindo dificuldades de modulação inicial do comportamento, bem como de funções cognitivas, pelos pacientes, diante do estímulo sexual, apoiando nossas hipótesesINTRODUCTION: Despite the serious behavioral consequences of individuals suffering from excessive sexual drive (ESD), neuropsychological studies are incipient and bring controversial results. OBJECTIVES: Through an experimental study of sexually impulsive subjects (patients) and non-sexually impulsive (control group) our aim was to compare: decision making and cognitive flexibility during basal wakefulness (Time \"0\"); decision making and cognitive flexibility at time \"0\" and after visual sexual stimulation (time \"1\") in each group (patients and control group) and among groups. METHOD: The study was developed at the ESD Clinic of the Psychiatry Institute (IPq), HC-FMUSP. The sample consisted of 30 patients and 30 people in the control group recruited through media coverage. Brazilian men, 18 years and older who met the diagnostic criteria for ISE (ICD - 10 - 52.7 F) and the Goodman criteria for addiction to sex were included as patients; while asymptomatic participants and that did not meet the above criteria were included in the control group. The neuropsychological research of the cognitive flexibility was made by applying the Wisconsin Card Sort Test (WCST), while the evaluation of the decision-making was made through the application of the Iowa Gambling Task (IGT) at time \"0\" and time \"1\" (after viewing an erotic video for 20 minutes), subject to a minimum interval of six months between times. In both times, the Sexual Compulsivity Scale was applied and to time \"1\", we applied the Sexual Arousal and Desire Inventory. RESULTS: During basal wakefulness patients presented a higher number of correct responses compared to the control group, in the test that investigates cognitive flexibility (p = 0.01). When comparing the performance of both groups to each other in between times, we found that the control group had a better initial performance (Block 1) in decision making (p = 0.01) as well as provided more correct answers in the test that evaluates cognitive flexibility (p = 0.01) at time \"1\". The same was not observed in the patients group. When comparing the average of the difference (time \"1\" - time \"0\") between the groups, we noted a better performance in the control group in what concerns the amount of correct responses (p = 0.02). CONCLUSION: As far as we know, this is the first study assessing executive functions in sexual impulsive, after exposure to sexual visual stimuli. As for the evaluation at basal wakefulness, patients presented better results regarding cognitive flexibility, opposite to the initial hypothesis. The control group presented a better performance concerning cognitive flexibility and initial decision making after exposure to sexual visual stimuli, when compared with results during basal wakefulness. When analyzing the performance difference after visual sexual stimulation compared with basal wakefulness in the two groups, the control group, once again, showed better cognitive performance. Such results indicate less impulsive initial choices and better cognitive flexibility after exposure to erotic stimulation in the control group, suggesting difficulties in the initial modulation of behavior, as well ass of cognitive functions, by patients before sexual stimulation, supporting our hypothesis

Testo completoAbstract (sommario):
I consider the relationship between natal dispersal, the acquisition of breeding resources and the proximate maintenance of the mating system in a population of song sparrows (Melospiza melodia) resident on Mandarte Island, B.C.. The general hypothesis tested was that intrasexual competition for the resources that limit reproduction in each sex is the main factor affecting patterns of natal dispersal, territory turnover and mating system organization. This study reveals differences in the competitive ability of individuals and the consequences of these for natal dispersal, territory acquisition and the ability to monopolize mates.
In this population, natal dispersal, territoriality and the mating system are related through the common mechanism of intrasexual competition for breeding resources. This competition affected reproduction within each sex, and in the opposite sex, raising potential conflicts of interest between mated males and females. I identify correlates of competitive ability, and consider how individuals of each sex maximize the number of young they raised.
All suitable habitat was defended even at low density, resulting in high levels of competition for space. Song sparrows contested for territories year-round. Most settlers were yearlings, but several males were older and had previously owned a territory. Most floaters settled by evicting owners from all or part of their territories, in contrast to the assumption of most models of dispersal that floaters gain territories only after an owner's death. Relative age and dominance within cohorts affected recruitment and territorial status in the year following hatch in each sex. Differences in age also affected territorial and mating behaviour, particularly in males. Although competitive ability varied with age, differences in competitive ability between males persisted through life.
Approximately 9% of male breeding attempts occurred after a male territory owner had evicted a neighbour and thereby gained access to an additional female. Polygynous males raised more young than monogamous males. Females vigorously defended their territories against female intruders, presumably to prevent polygyny by their mates. Females in polygynous groups often lost the aid of their mate, and raised fewer young, because polygynous males did not aid two females simultaneously. Adding supplemental food altered female time budgets, increased their ability to prevent settlement by female floaters, and increased their reproductive success. This suggests that females are constrained in the amount of time they can spend in territory defence by time spent foraging. The maintenance of monogamy was affected by differences in the abilities of individual males and females to defend their territories against intruders of the same sex. Dispersal distances were similar among sexes, in contrast to the usual pattern of female-biased dispersal in birds. Given the intense territorial behaviour of males and females, this study supports the hypothesis that biases in dispersal arise when territory establishment is substantially more difficult in one sex than the other. Dispersal on Mandarte was unrelated to inbreeding, common parentage, or reproductive success. However, emigrants from Mandarte were socially subordinate birds that must have outbred if they settled successfully. Female emigrants from local populations in the vicinity of Mandarte may settle more often than males. Dispersal occurred as young birds established ranges in the period following independence, from which they challenged or replaced owners. Adding food during the breeding period reduced dispersal in males and females in late summer and the following spring. Competitive ability probably affects dispersal from the natal population, the likelihood of settlement, and the time of settlement for those birds that remain in the natal population.Science, Faculty of

Testo completoAbstract (sommario):
Much published work has pointed to the need for the development of a sound operational definition of sexual orientation in order to enable the research in this area to progress. To contribute to this process the current research set out to develop two measures of sexual orientation and examine their psychometric properties. In order to develop relevant tools historical, conceptual and operational definitions of sexual orientation were critically examined and standard questionnaire development techniques applied. The first scale consisted of 32 items and was administered to a total of 835 adolescents, comprising three sub-groups (189 Grade 11 Scholars, 547 First Year and 99 Third Year Psychology Students). A Cronbach alpha coefficient of 0.85 was calculated indicating that this instrument had very good internal consistency reliability. Similar factors emerged in each of the sample sub-groups when factor analyses were performed suggesting that this instrument has good external and construct validities. These factors each had respectable Cronbach alpha coefficients indicating their own internal consistency. The four factors which consistently emerged were Same Sex Responsiveness, Opposite Sex Responsiveness, Previous Month’s Same Sex Responsiveness and Previous Month’s Opposite Sex Responsiveness. The second scale consisted of 16 items and was administered to 646 adolescents, comprising the latter two sub-groups referred to above. A Cronbach alpha coefficient of 0.82 was calculated indicating that this instrument also had very good internal consistency reliability. Once again similar factors with generally good internal consistency emerged in factor analysis suggesting that this too was a valid instrument. The factors that emerged from the second scale were Same Sex Responsiveness, Unattractive Opposite Sex Responsiveness, Attractive Opposite Sex Responsiveness and Attraction. Future developments, adjustments and applications of the instruments as well as implications for the arena of sexual orientation research are discussed. In the light of the dearth of information with regard to the sexual orientations of South African adolescents the current study also briefly explored and presented the sample’s responses in terms of the dimensions of each questionnaire as well as how each emerging factor related to the demographics (education level, gender, sexual orientation self-label and age) of the sample.

Testo completoAbstract (sommario):
Risky sexual behavior (RSB) is the number one transmission method of HIV among adolescents. Reducing the rates of HIV among adolescents is of dire importance considering the rises in rates during the last several years. Minority adolescents are disproportionately affected by HIV, and a majority of the individuals living in Miami-Dade County (location of the proposed project) are minorities. RSB, externalizing disorders and cannabis use commonly occur together, such that both greater externalizing disorder symptoms and greater amounts of cannabis use have predicted engagement in more RSB. In addition, decision-making (a neurocognitive function) has found to be associated with cannabis use, externalizing disorders, and RSB. Little research has been conducted on these factors among adolescents. No study has evaluated externalizing disorders, cannabis use and decision-making together to determine the unique contribution of each factor to RSB among a sample of adolescents.
The current study used the infrastructure and participants of an existing project examining how decision-making abilities and memory performance are impacted by cannabis use during adolescence. Structural equation modeling and multiple linear regression were used to analyze how externalizing disorders, cannabis use, and decision-making predict RSB. Results suggest that externalizing symptoms, cannabis use and some decision-making tasks predict RSB. Several interactions effects emerged between externalizing symptoms and decision-making tasks, cannabis use and decision-making tasks as well as externalizing symptoms and cannabis use to predict RSB. The results of the study will help future prevention and intervention efforts such that interventions can be tailored to address the areas that contribute the most to RSB among adolescents. Furthermore, cognitive skill building is one possible intervention that may be beneficial to adolescents with poorer decision-making performance.

Homeless youth face numerous risks. Data on 602 homeless youth from the Midwest Homeless and Runaway Study and binary logistic regression were used to identify factors associated with their participation in risky sexual behaviors. Specifically, the effects of abuse/neglect and three potential moderating resiliency indicators, namely self-esteem, parental warmth, and parental monitoring, on having sex before adulthood and thinking about trading sex for food or shelter were examined. While none of the three resiliency indicators had the hypothesized moderating effects, controlling for abuse/neglect and various sociodemographic characteristics, parental monitoring had a direct, negative effect on having sex before adulthood, and self-esteem and parental warmth had direct, negative effects on thinking about trading sex for food or shelter. Policy implications of the findings are discussed.

The purpose of the present study was to compare the scores of the Beck Depression Inventory, State-Trait Anxiety Inventory, and the Coopersmith Inventory of heterosexual men with compulsive sexual behavior (N = 22), homosexual men with compulsive sexual behavior (N = 19), heterosexual men without compulsive sexual behavior (N = 38), and homosexual men without compulsive sexual behavior (N = 8). The Sex Addiction Screening Test was used to determined placement in a group. Findings revealed men who exhibit compulsive sexual behavior are significantly more depressed, experience lower self-esteem and have higher state anxiety (situational) than controls.
