Several decades of research have identified the contributions of psychosocial influences on adolescent and young adult sexual behavior; however, few studies have examined parental and peer influence and sexual values during the transition from high school to college. The current study tested the influence of sexual values and perceived awareness and caring (PAC), or beliefs about how much parents and peers know and care about students' behavior, on sexual behavior during this transitional period. Using data from a longitudinal study, generalized estimating equations and the generalized linear model were used to examine the associations among sexual values, parental and peer PAC, and sexual behavior, both cross-sectionally and longitudinally. Participants (N = 1,847; 61% female) completed web-based surveys the summer before college matriculation and at the end of the first semester in college. Results indicated that individuals with high levels of both parental and peer PAC engaged in less frequent sexual behaviors and that PAC moderated the effect of sexual values on sexual behaviors. Furthermore, both PAC variables decreased during the transition from high school to college, and high school sexual values, parental PAC, and their interaction predicted the number of sexual partners during the first semester of college. Only sexual values and high school unsafe sexual behaviors predicted unsafe sexual behavior in college. Findings suggest that complex associations exist among perceived awareness and caring, sexual values, and sexual behaviors, and that the transition from high school to college may be an ideal time for safer-sex interventions.
几十年来的研究已经确定了心理社会因素对青少年和年轻成年人性行为的影响；然而，很少有研究探讨过父母和同伴的影响以及性价值观在从高中到大学的过渡期间的作用。本研究检验了性价值观以及感知到的父母和同伴的了解和关心程度（PAC），即对父母和同伴了解和关心学生行为的程度的信念，对这一过渡期间性行为的影响。本研究使用来自一项纵向研究的数据，通过广义估计方程和广义线性模型，从横向和纵向两个方面检验了性价值观、父母和同伴 PAC 与性行为之间的关联。研究参与者（N=1847；61%为女性）在大学入学前的暑假和大学第一学期末完成了在线调查。结果表明，父母和同伴 PAC 水平都较高的个体性行为频率较低，PAC 调节了性价值观对性行为的影响。此外，从高中到大学的过渡期间，PAC 变量都有所下降，高中时期的性价值观、父母 PAC 及其相互作用预测了大学第一学期的性伴侣数量。只有性价值观和高中时期的不安全性行为预测了大学时期的不安全性行为。研究结果表明，感知到的了解和关心程度、性价值观和性行为之间存在复杂的关联，从高中到大学的过渡期间可能是进行安全性行为干预的理想时机。
