Abstract

Purpose

An early age of sexual initiation and sexual activity with multiple partners are risk factors for an array of detrimental outcomes. Drawing on social norms theory, this study assessed the role of subjective and descriptive social norms from parents, peers, and schoolmates on trajectories of sexual partner accumulation from early adolescence through early adulthood.

Methods

Data were drawn from the in-home survey sample of Add Health, following 14,797 youth from adolescence through early adulthood. Social norms data were drawn from youth, parent, schoolmate, and school administrator reports. Multi-level growth models assess how parent, peer, and school social norms predicted initial levels and growth in sexual partner accumulation.

Results

Parent and peer approval of youth sexual behavior, as well as lower perceived negative repercussions of pregnancy, predicted greater initial levels and greater growth over time in the accumulation of sexual partners. Similarly, youth attending schools with a greater proportion of sexually experienced schoolmates reported higher initial levels of sexual partners. In contrast, greater parental warnings regarding negative consequences of sex predicted heightened sexual partner accumulation. Some moderation by youth gender and age emerged as well.

Conclusions

Results highlight the role of both subjective and descriptive social norms, suggesting the importance of understanding and seeking to influence the social beliefs and expectations of youth and their families.

Sampling and data collection

Data were drawn from the in-home survey sample of the National Longitudinal Study of Adolescent Health (Add Health), a longitudinal survey of a nationally representative school-based sample of adolescents in the United States. From the baseline school sample, a stratified sample of 7th through 12th graders was selected for the in-home surveys. This sample was interviewed over four waves in 1995, 1996, 2001/2, and 2007/8, with response rates of 79%, 88%, 77%, and 80% respectively. Youth averaged

Descriptive results

Table 1 presents descriptive statistics on the imputed, weighted sample. On average, youth reported just under one partner at Wave 1, rising to more than one partner at Wave 2, and to over 11 partners by Wave 4, when youth averaged 29 years old. Although 69% of youth reported 0 sexual partners at Wave 1, this dropped quickly, to 14% by Wave 3 and 4% by Wave 4, supporting the use of a Poisson model.

Discussion

Results from this study illustrate the important role that subjective and descriptive social norms from parents, peers, and schoolmates may play in predicting youths’ accumulation of sexual partners from early adolescence through early adulthood, an important risk factor for negative consequences such as STIs and unplanned pregnancies. Perhaps the strongest and most consistent pattern unearthed in this nationally representative sample was the role of youths’ perceptions of parent and peer

      However, longer-term longitudinal research suggests that adolescents who were closer to their peers were less likely to engage in sexual intercourse in adolescence, but there were no differences in young adult behavior [25]. However, peer norms about sexual behavior may play an important role; one study found that feeling that peers were more accepting of sexual behavior were associated with more partners in adolescence and greater growth in number of partners through young adulthood [27]. Individuals who attend a school with a higher percentage of sexually experienced students have more sexual partners but do not experience greater growth in number of partners through young adulthood [27].

      The primary theories in the social-psychological domain include social learning theory, social control theory, and attachment theory. Studies of sexual risk behavior based on these theories typically focus on the variations in parental quality, parental supervision, and affiliation with promiscuous peer groups (Beyers et al., 2015; Caruthers et al., 2014; Coley et al., 2013; DelPriore & Hill, 2013; DelPriore et al., 2017, 2018; Dishion et al., 2004; Ellis et al., 2012; Kalina et al., 2013; Quinlan, 2003) all of which have implications for exposure to adversity either by way of lack of care or lack of supervision and protection. With respect to parental influences, Buhi and Goodson (2007) provided a review of studies testing parental effects and found consistent evidence that individuals with more parental support and more parental monitoring and supervision pursued sex at later ages and had fewer sexual partners (Benda & Corwyn, 1998; Browning et al., 2004; Davis, & Friel, 2001; Huebner & Howell, 2003; Li et al., 2000; Miller et al., 1997, 2000; Ramirez-Valles et al., 2002; Roche et al., 2005; Rosenthal et al., 2001; Somers & Paulson, 2000).

      However, Jaccard and Dittus (2000) did not find a consistent effect of maternal approval of contraception on subsequent pregnancy risk. Lastly, Coley et al. (2013) found that norms operationalized as parent and peer approval of sex, and attending school with a greater proportion of sexually experienced schoolmates, predicted a greater accumulation of sexual partners; however, greater parental warnings regarding the negative consequences of sex predicted greater accumulation of partners as well. At the individual level, positive attitudes and beliefs about contraception have been shown to consistently predict higher contraception use, the most important method of avoiding both unwanted pregnancy and STIs (Buhi and Goodson, 2007; Malcolm et al., 2013).
