Moderators and Mediators of Within-Person Risk for Contact and Non-Contact Sexual Aggression in College Men - Project Abstract Alcohol use and a variety of other attitudinal, behavioral, and cognitive variables are reliable predictors of sexually aggressive behavior (SAB). However, studies using longitudinal designs have not typically examined within-person risk factors for SAB that are unconfounded by between-person variability, even though within- person risk (and protective) factors that covary with SAB perpetration are likely to be the most effective prevention/intervention targets. Although a small number of daily diary or ecological momentary assessment (EMA) studies have disaggregated within- from between-person risk for SAB, very low base rates of SAB (~5- 8% past year) create significant challenges for this approach. The current study will address these challenges and gaps in the literature by disaggregating between- from within-person risk factors for SAB using a longitudinal burst design, and by looking at non-contact SAB as well as contact SAB. Collecting data across multiple EMA bursts (e.g., every 6 months) will increase our power to detect effects at the daily level, as will the use of our newly developed measure of non-contact SAB that has a higher base rate (~40% past year) and correlates reliably with contact SAB. At the daily level, we will examine the effects of alcohol consumption and drinking context on SAB, as well as the potential mediation of these relations by sexual arousal and key protective factors: Protective Behavioral Strategies (PBS) for SAB, risky sexual behavior, and heavy episodic drinking (HED). The PBS findings may have important implications for prevention and early intervention as PBS for HED have been identified as an important target of effective prevention/early intervention approaches. We also will examine partner type (new vs. existing), cannabis use, and sexual judgement and decision- making (JDM) as potential moderators. Moreover, we will compare the magnitude of the mediated and moderated effects for non-contact and contact SAB. The focus on day-level moderators and mediators will identify important contexts for (i.e., sex with a new partner, co-use of alcohol and cannabis) and targets of `in- the-moment' interventions (i.e., sexual arousal, PBS). Finally, at the burst level, we will determine whether noncontact SAB prospectively predicts contact SAB, while controlling for prior contact SAB, which could greatly inform theory and prevention efforts. We will accomplish these goals by recruiting a sample of 300 male college students (ages 18-20) to complete traditional survey measures and 28 days of daily assessments (EMA) bi-annually (4 total surveys and EMA bursts). Multilevel models will disaggregate between- and within- person effects and examine main effects and moderated and mediated effects at the daily level. The ultimate goal of this work is to inform the development and refinement of prevention programs designed to reduce SAB. MPIs Corbin and Treat recently completed a study examining the efficacy of a computer-delivered prevention program combining cognitive retraining and normative feedback (NIAAA R34 AA027713) and are therefore well positioned to translate the daily-level findings to ecological momentary intervention efforts.
