Sexuality (and Lack Thereof) in Adolescence and Early Adulthood: A Review of the Literature

Youth sexuality has been primarily studied with a focus on its potential public health issues, such as sexually transmitted infections and unwanted pregnancies, and its comorbidity with other risky behaviors. More recently, it has been studied as a normative step in romantic partnerships, either pre- or post-marital, as well as outside the context of romantic involvement. In this paper, we review the extensive literature on sexuality in adolescence and early adulthood both within and outside romantic relationships (i.e., casual sexual relationships and experiences; CSREs). Furthermore, the recent recognition of youth sexuality as a developmental task has led to a renewed interest from scholars in youth who abstain from sexual encounters, whether deliberately or not. A brief overview of the literature on cultural differences in sexuality, and sexual-minority youth sexual development is also provided. This paper concludes by suggesting future directions to bring the field of youth sexuality and romantic relationships forward.

Project STARS (Studies on Trajectories of Adolescent Relationships and Sexuality): A longitudinal, multi-domain study on sexual development of Dutch adolescents

This study gives an overview of Project STARS (Studies on Trajectories of Adolescent Relationships and Sexuality), a four-wave longitudinal study of 1297 Dutch adolescents. First, the sample, measures and four sub-projects are described. Second, hierarchical regression analyses were conducted to examine how key variables from the individual domain (impulsivity), parent domain (parent–adolescent relationship quality), peer domain (involvement with peers) and media domain (time spent on social networking sites), and their interactions predict changes in the experience with sexual behaviour of adolescents across time. Results showed that higher levels of impulsivity, lower quality of relation with parents, more frequent involvement with peers and more time spent on social networking sites at baseline predicted increases in sexual experience of adolescents over a subsequent 1.5-year time period. No interaction effects among the domains were found. The findings highlight the significance of a multi-domain approach to the study of adolescent sexual development.

Early Sexual Intercourse : Prospective Associations with Adolescents Physical Activity and Screen Time

Objectives To assess the prospective associations of physical activity behaviors and screen time with early sexual intercourse initiation (i.e., before 15 years) in a large sample of adolescents. Methods We used two waves of data from the Rotterdam Youth Monitor, a longitudinal study conducted in the Netherlands. The analysis sample consisted of 2,141 adolescents aged 12 to 14 years (mean age at baseline = 12.2 years, SD = 0.43). Physical activity (e.g., sports outside school), screen time (e.g., computer use), and early sexual intercourse initiation were assessed by means of self-report questionnaires. Logistic regression models were tested to assess the associations of physical activity behaviors and screen time (separately and simultaneously) with early sexual intercourse initiation, controlling for confounders (i.e., socio-demographics and substance use). Interaction effects with gender were tested to assess whether these associations differed significantly between boys and girls. Results The only physical activity behavior that was a significant predictor of early sexual intercourse initiation was sports club membership. Adolescent boys and girls who were members of a sports club) were more likely to have had early sex (OR = 2.17; 95% CI = 1.33, 3.56. Significant gender interaction effects indicated that boys who watched TV ≥2 hours/day (OR = 2.00; 95% CI = 1.08, 3.68) and girls who used the computer ≥2 hours/day (OR = 3.92; 95% CI = 1.76, 8.69) were also significantly more likely to have engaged in early sex. Conclusion These findings have implications for professionals in general pediatric healthcare, sexual health educators, policy makers, and parents, who should be aware of these possible prospective links between sports club membership, TV watching (for boys), and computer use (for girls), and early sexual intercourse initiation. However, continued research on determinants of adolescents’ early sexual initiation is needed to further contribute to the strategies for improving adolescents’ healthy sexual development and behaviors.

Observed Normativity and Deviance in Friendship Dyads’ Conversations About Sex and the Relations With Youths’ Perceived Sexual Peer Norms

The current study examined the relations between observed normativity and deviance during adolescents’ and young adults’ conversations about sex with their friends and their individual perceptions of sexual peer norms. Participants were 16–21-year-old same-sex friendship dyads (31 male and 30 female dyads) who performed a peer interaction task that consisted of five discussion assignments focusing on party planning, sexual double standards, condom use, homosexuality, and consensual sex. Videotaped discussions were coded to capture the amounts of normative talk (e.g., consistent with notions of healthy sexuality) and deviant talk (e.g., consistent with notions of risky sexuality), and the verbal or nonverbal reinforcement thereof. Participants also completed individual questionnaires to assess their perceived sexual descriptive norms, injunctive norms, pressure, and risk norms among their peers. Actor–partner interdependence model (APIM) results revealed that youths’ perceived descriptive, injunctive, and risk norms, but not their experienced peer pressure, were related to both their own (actor effects) and their friends’ (partner effects) normativity and deviance. Overall, more deviance was related to perceiving friends to be more sexually active, more approving of having sex, and engaging in more risky sex, whereas more normativity was related to these perceptions in the opposite direction. Gender differences in the APIMs indicated that interactive normativity and deviance was related to perceived descriptive, injunctive, and risk norms for boys, but only to perceived injunctive norms for girls. These findings demonstrate the importance of assessing the dyadic nature of youths’ sexual communication with friends, their relation to individual sexual peer norm perceptions, and gender differences therein.

Mother– and father–adolescent relationships and early sexual intercourse

OBJECTIVES: To assess the prospective associations between mother-adolescent and father-adolescent relationship quality and early sexual intercourse initiation (ie, ≤16 years) among a large sample of Dutch adolescents. METHODS: Two waves of data from the Rotterdam Youth Monitor, a longitudinal study in the Netherlands, were used. The analysis sample consisted of 2931 adolescents aged 12 to 16 years (Meanage@T1 = 12.5 years, SD = 0.61; Meanage@T2 = 14.3 years, SD = 0.60). Variables were assessed by means of self-report questionnaires. Prospective associations between mother-adolescent and father-adolescent relationships and early sexual initiation were assessed by logistic regression analyses, stratified by gender, controlling for various potential confounders. RESULTS: We found that only girls (not boys) having a higher-quality relationship with mothers were significantly less likely to have initiated early sexual intercourse between T1 and T2. Bivariate findings showed that both girls and boys having a higher-quality relationship with their father at T1 were significantly less likely to have engaged in early sexual intercourse between T1 and T2, but when assessed multivariately, these associations were no longer significant, neither for boys nor for girls. CONCLUSIONS: Our findings suggest that a higher-quality relationship between adolescents and their parents, especially between mothers and daughters, may help to protect against early sexual initiation. Pediatricians and other health care professionals should be able to explain to parents that early sexual intercourse initiation can be associated with negative health outcomes, but that parents can play an important role in promoting healthy sexual behaviors.

Buffer or Brake? The Role of Sexuality-Specific Parenting in Adolescents’ Sexualized Media Consumption and Sexual Development

One main source of sexual socialization lies within family interactions. Especially sexuality-specific parenting may determine adolescents’ sexual development—adolescents’ sexual behavior and sexual risk behavior, sexualized media consumption and permissive sexual attitudes—to a significant extent, but different ideas exist about how this works. In this longitudinal study, we examined two hypotheses on how sexuality-specific parenting—parenting aimed specifically at children’s sexual attitudes and behaviors—relates to adolescents’ sexual development. A first buffer hypothesis states that parents’ instructive media discussions with their children—called instructive mediation—buffers the effect of sexualized media consumption on adolescents’ sexual attitudes and behavior and, vice versa, the effect of adolescents’ sexual attitudes and behavior on sexualized media consumption. A second brake hypothesis states that parents, by communicating love-and-respect oriented sexual norms, slow down adolescents’ development toward increased sexualized media use, permissive sexual attitudes, and sexual behavior and sexual risk behavior. Using four-wave longitudinal data from 514 Dutch adolescents aged 13–16 years (49.8% female), we found evidence to support a brake effect. More frequent parental communication of love-and-respect oriented sexual norms was associated with less permissive sexual attitudes and, for boys, with less advanced sexual behavior and a less rapid increase in sexual risk behavior. Parents’ instructive mediation regarding adolescents’ sexualized media consumption was associated with less permissive sexual attitudes at baseline, but only for girls. No systematic evidence emerged for a buffer effect of parents’ instructive mediation. In conclusion, although our data seem to suggest that parent–child communication about sex is oftentimes “after the fact”, we also find that more directive parental communication that conveys love-and-respect oriented sexual norms brake adolescents’ move toward sexual maturity.

Vroeg seksueel debuut in Nederland

Vroeg seksueel debuut brengt potentiele risico’s met zich mee, zoals onveilige en ongewenste seksuele ervaringen. Deze longitudinale studie onderzocht de gezamenlijke en relatieve rol van biopsychosociale factoren in de timing van seksueel debuut. Nederlandse adolescenten (n = 366) vulden drie keer vragenlijsten in (interval: een jaar). Voor de ancova’s en logistische regressieanalyses (apart uitgevoerd voor jongens en meisjes) zijn twee groepen gemaakt: debuut <16 en debuut ≥16. In lijn met het biopsychosociale model werden significante effecten gevonden voor zowel individuele als sociale factoren. Wanneer deze factoren tegelijkertijd werden onderzocht, bleek dat, zowel voor meisjes als voor jongens, leeftijdgenoten de meest belangrijke voorspellers waren van vroeg seksueel debuut. De bevindingen belichten aandachtspunten voor preventie- en interventieprogramma’s voor adolescenten en ouders.
