The role of substance misuse and sexual victimization history on sexual violence risk perception in men who have sex with men: A novel paradigm.

Objective: Sexual victimization (SV) is common among men who have sex with men (MSM) as is dating and sexual networking (DSN) app use. We developed a novel laboratory paradigm ("G-Date") of sexual violence risk perception in DSN app environments and explored its validity and the role of substance misuse and SV history on sexual violence risk perception.

Method: Using convenience sampling, we recruited 145 MSM to use G-Date to interact with two bogus speed dates whose responses were scripted to be risky or non-risky. Risky dates displayed several cues indicating risk for sexual violence perpetration. Dependent variables included pre/post changes in ratings of their dating partner's appeal; ratings of the presence of each of the embedded risk cues; and the duration of the speed dates.

Results: Compared to non-risky dates, participants terminated risky dates significantly sooner, rated them higher in each of the risk cues, and their pre- to post-date ratings of partner appeal declined significantly more. Participants' drug misuse was associated with reduced interest in the non-risky date, but not the risky date and predicted shorter speed date length and lower partner appeal ratings across date type. Substance-facilitated SV history interacted with alcohol misuse and date type to predict sexual violence risk perception.

Conclusions: Results provide evidence for the paradigm's validity and suggest that drug misuse and substance-facilitated SV history shape MSM's risk perception in DSN apps. Efforts to prevent SV among MSM should consider individual characteristics, including substance misuse, in risk perception.
