Motivations for and against sex are salient predictors of engaging in or abstaining from sex in cross-sectional studies. Participants (N = 637, 41.4% male) provided data on their motivations for and against sex and lifetime sexual behavior prior to entering college and six months into the first year in college. Longitudinal data were used to examine differences on motivations for and against sex reported the summer before college entrance for students who continued to abstain (Nevers, 44.7%), transitioned to sexual behavior in the following months (Transitioners, 11.0%), and who were previously sexually active (Actives, 44.3%). Multivariate analysis of variance analyses indicated that Transitioners evidenced mean-level differences in motivations surrounding sex (greater intimacy and enhancement motives for sex, lower values motives against sex) prior to their behavioral initiation compared to Nevers. In addition, Transitioners reported greater changes in motivations from pre-college to the six-month follow-up, including increased enhancement motivations for sex and decreased values and not ready motivations against sex. Men reported more important motivations for sex and less important motivations against sex than women, with an interaction showing that sexually experienced women reported more important intimacy motivations and sexually inexperienced men reported more important coping motivations for sex. Identifying salient motivations associated with imminent changes in sexual behavior may support the development of sexual health promotion programs that seek to reach sexually inexperienced individuals at important times of transition.
性动机无论是促进还是阻碍性行为,都是横断面研究中预测人们进行或避免性行为的重要因素。参与者(N=637,41.4%为男性)在进入大学前和大学第一年的第六个月提供了关于他们进行或避免性行为的动机以及终生性行为的数据。纵向数据用于检查在进入大学前的那个夏天,那些继续保持禁欲的学生(从不者,44.7%)、在接下来的几个月里过渡到性行为的学生(过渡者,11.0%)和之前有过性行为的学生(活跃者,44.3%)报告的性动机差异。多变量方差分析表明,与从不者相比,在行为开始前,过渡者在性动机方面表现出平均水平的差异(性的亲密和增强动机更大,反对性的价值动机更小)。此外,与从不者相比,过渡者从大学前到六个月随访期间的动机变化更大,包括增强性的增强动机和减少价值和未准备好的反对性的动机。与女性相比,男性报告的性动机更重要,反对性的动机更不重要,而且有一个交互作用表明,有性经验的女性报告的亲密动机更重要,没有性经验的男性报告的应对性动机更重要。确定与性行为即将发生变化相关的重要动机可能有助于制定性健康促进计划,以在重要的过渡时期接触到没有性经验的个体。
