我们采用纵向突发设计（N= 213,6487人日）测试了酒精对年轻人性行为的人体内影响，使用的数据来自先前发表的一项父母研究。我们通过测试一个有四种结果（无性行为、无性交的口交、有保护的性交和无保护的性交）的多层次多项模型，区分了酒精对性行为可能性的影响，以及对性行为预防措施或怀孕的影响。在个人水平上，酒精的影响被假设为有条件的中毒水平（即，曲线效应）。我们还测试了四个人与人之间的调节因素的影响：性别，与性伴侣的典型关系长度，以及自我控制的两个方面（努力控制和反应性）。与我们的假设一致，低水平的醉酒与口交或有保护性交（相对于无性行为）的可能性增加有关，但与无保护性交的可能性无关。醉酒对无保护性交和无保护性交的影响呈加速曲线，在高水平醉酒时显著增加无保护性交的可能性。人与人之间的因素缓和了醉酒和性行为之间的联系。对于性伴侣更熟悉的个体，酒精中毒对保护性和无保护性性交的影响减弱。努力控制表现出保护作用，减少醉酒对无保护性交可能性的影响。反应性的假设效应不被支持。相对于男性，醉酒是口交和有保护性交（但不是无保护性交）的女性更强的预测因子。结果强调了酒精与性行为关系的内在复杂性。
We tested within-person effects of alcohol on sexual behavior among young adults in a longitudinal burst design (N=213, 6487 person-days) using data collected from a previously published parent study. We differentiated effects of alcohol on likelihood of sexual activity versus use of protection against STDs or pregnancy on intercourse occasions by testing a multilevel multinomial model with four outcomes (no sex, oral sex without intercourse, protected intercourse, and unprotected intercourse). At the within-person level, effects of alcohol were hypothesized to be conditional upon level of intoxication (i.e., curvilinear effect). We also tested effects of four between-person moderators: gender, typical length of relationship with sexual partners, and two facets of self-control (effortful control and reactivity). Consistent with our hypothesis, low-level intoxication was associated with increased likelihood of engaging in oral sex or protected intercourse (relative to no sex) but was not related to likelihood of unprotected intercourse. The effect of intoxication on unprotected versus protected intercourse was an accelerating curve, significantly increasing likelihood of unprotected intercourse at high levels of intoxication. Between-person factors moderated associations between intoxication and sexual behavior. Effects of intoxication on both protected and unprotected intercourse were diminished for individuals with more familiar sexual partners. Effortful control exhibited a protective effect, reducing the effects of intoxication on likelihood of unprotected intercourse. Hypothesized effects of reactivity were not supported. Intoxication was a stronger predictor of oral sex and protected intercourse (but not unprotected intercourse) for women relative to men. Results highlight the inherent complexities of the alcohol-sexual behavior nexus.
