3-Month Usability

The 10-item System Usability Scale will be used to evaluate the usability of WebApp in the intervention group only. The System Usability Scale (Brook, 1996) includes 10 items that are rated from 1 (Strongly Disagree) to 5 (Strongly Agree). To get a final score the: 1) First, one is subtracted from the score of the odd items; 2) Second, the responses are subtracted from 5 for the even-numbered items; 3) Then the responses are summed and multiplied by 2.5 to get a range of 0-100. A score above 68 is considered above average.

5-Month Usability

3-Month Acceptability

The 5-item System Acceptability Scale (investigator created) will be used to evaluate the acceptability of the WebApp in the intervention group only. An investigator-created acceptability scale with 5-items will be used to measure acceptability. Four items are scored from 1 (Strongly Agree/Very Likely) to 5 (Strongly Disagree/Very Unlikely) and will be reverse coded. One item assess the frequency of use of the WebApp from 1 (Never) to 5 (Multiple times a week). All five items will be summed for a total score. Scores range from 5-25, with higher scores indicating greater acceptability.

3-Month Retention

The retention rate will be calculated based on how many participants in the intervention group have completed the follow-up surveys. A total retention score (those retained/those enrolled) will be computed based on interaction with the WebApp.

3-Month Sexual Violence Victimization

The 10-item Sexual Experiences Survey will be used to measure participants' experiences of sexual violence victimization. The revised Sexual Experiences Survey - Short Form Victimization (Koss et al., 2007) includes 10 items that are used to assess the frequency of seven victimization behaviors and then uses three questions to explore the sex of the perpetrator and if the participant believes they were raped. We will be items 1-7 to assess the number of times an individual has experienced victimization over the last 3 months from 0 to 3+ times. The results will be scored as a percentage of participants who have experienced each individual behavior and the percentage who report that they have experienced a rape.
