Trauma exposure, alcohol consumption, and sleep quality: a latent growth curve model.

This study examined the relations among precollege trauma exposure, alcohol use upon entering college, growth in alcohol use, and sleep quality in a sample of undergraduate students. Participants were 932 students from a large, urban, public university. Participants completed a survey upon entering college and then subsequent follow-up surveys each Spring semester. Precollege trauma exposure was associated with both baseline and growth in alcohol use, whereby higher levels of trauma were associated with higher baseline alcohol use, but with less steep increases in growth rate, as compared to those with lower levels of trauma. Baseline alcohol use was associated with sleep quality whereby those with higher levels of consumption demonstrated worsened sleep quality. This study provides longitudinal evidence for the relations among trauma, alcohol use, and sleep quality. Although the relationship between trauma and alcohol is well-established, further work is needed to identify how this relationship impacts additional health outcomes.

Prevalence and predictors of sexual assault among a college sample.

OBJECTIVE: This study examined the prevalence and correlates of precollege, college-onset, and repeat sexual assault (SA) within a representative student sample. PARTICIPANTS: A representative sample of 7,603 students. METHODS: Incoming first-year students completed a survey about their exposure to broad SA prior to college, prior trauma, personality, relationships, and mental health. Broad SA was then reassessed each spring semester while enrolled. RESULTS: Nearly 20% of the sample reported experiencing broad SA, with women endorsing significantly higher rates compared with males. Prior victimization before coming to college was related to a greater risk of victimization in college, and there was no statistically significant difference between males and females who reported revictimization. Correlates of college-onset broad SA were found and are discussed. CONCLUSIONS: Given the need for SA intervention and prevention on college campuses, identification of factors potentially contributing to exposure within this population is essential.
