Efficacy of a Web-based Sexual Violence Risk Reduction Program for Female College Students

Sexual assault victimization was assessed with Revised Sexual Experience Survey. Participants were asked how often they experienced 7 unwanted sexual experiences. Also, the tactic that was used ("using force") was also noted. Response options ranged from 0 (never) to 3 (3+times). An overall score for the SES, was calculated by summing each outcome and tactic score ("SOTS") with a range from 0 to 135- with higher scores indicating more sexual violence victimization. The 2nd method combines several of the outcomes, but keeps tactics separate, resulting in a potential range of 0 to 63.

Alcohol protective behaviors was measured by a scale developed by Martens et al., 2005 that included 15 protective strategies (e.g.., "alternate alcoholic and non-alcoholic drinks") that asked participants if they had engaged in within the last 3 months. with response options of Never (1) to Always (5). Responses were summed across the 15 items. Potential range was 15 to 75. Higher scores indicated MORE protective strategies were used.

Dating Risk Behaviors were measured by the Dating Behavior Survey created by Hanson & Gidycz, 1993. The scale consists of 15 items that assess different situational variables (e.g., "consuming alcohol on the first date") that have been found to be related to sexual violence victimization. Participants are asked to respond how often they have engaged in the behavior on the first few dates with a new partner. Response options ranged from Never (1) to Always (5). Scores are summed and higher scores indicate engaging in MORE risk behaviors. Overall scores can range from 15 to 75.

Participants were asked at baseline and at 6-month follow-up, to report: "In the past 30 days, the number of times four or more drinks were consumed in one setting."

Participants were asked at baseline and at 6-month follow-up to report, "the average number of alcoholic drinks consumed per occasion in the last 30 days."

Bystander behavior was assessed using the 20-item Bystander Behavior Scale. Items assessed whether participants engaged in bystander behaviors in the past three months and included items such as, "If I saw someone taking a very intoxicated person up to their room, I said something and asked what the friend was doing." Higher scores indicate a better outcome of engaging in more prosocial behaviors. Min value=0; Max value=60.
