College women report high rates of sexual assault. Research focused on women's risk factors for sexual assault remains necessary to assist women in reducing their risk. Previous work has shown alcohol use and cannabis use to be associated with sexual assault. The current study examined whether individual difference variables moderated women's risk for sexual assault during occasions of alcohol use and cannabis use using ecological momentary assessment (EMA).
Participants were 18- to 24-year-old first-year undergraduate women ( = 101) who were unmarried and interested in dating men, consumed three or more alcoholic drinks on one occasion in the month before baseline, and engaged in sexual intercourse at least once. Baseline individual difference variables included sex-related alcohol expectancies, alcohol problems, decision skills, and sexual attitudes. EMA reports, collected three times per day over 42 days, included items regarding alcohol and cannabis use and sexual assault experiences.
Among women who experienced sexual assault during the EMA period ( = 40), those with higher sexual risk expectancies had a higher probability of sexual assault during occasions when they were using alcohol or cannabis.
Several modifiable risk factors for sexual assault and individual differences factors may exacerbate risk. Ecological momentary interventions may be useful to reduce sexual assault risk for women with high sexual risk expectancies who use alcohol or cannabis.
女大学生报告称性侵犯发生率很高。研究集中在女性遭受性侵犯的风险因素上，这对于帮助女性降低风险仍然是必要的。先前的研究表明，饮酒和吸食大麻与性侵犯有关。本研究使用生态瞬时评估（EMA），检查个体差异变量是否会在女性饮酒和吸食大麻时影响其性侵犯风险。
参与者为 18 至 24 岁的一年级本科女大学生（n=101），未婚且对与男性约会感兴趣，在基线前一个月的一次中饮用了三杯或更多的含酒精饮料，并至少有一次性交经历。基线个体差异变量包括与性相关的酒精期望、酒精问题、决策技能和性态度。在 42 天的时间内，每天收集 3 次 EMA 报告，包括关于酒精和大麻使用以及性侵犯经历的项目。
在 EMA 期间经历性侵犯的女性中（n=40），性风险期望较高的女性在饮酒或吸食大麻时发生性侵犯的可能性更高。
几种可改变的性侵犯风险因素和个体差异因素可能会加剧风险。生态瞬时干预措施可能对那些有较高性风险期望、饮酒或吸食大麻的女性减少性侵犯风险有用。
