简要总结
Sexual assault victimization is a common and particularly harmful form of trauma that is associated with increased risk for high-risk drinking and other conditions of public health concern, such as PTSD. Given evidence that sexual assault survivors who have low social support or receive negative social reactions to sexual assault disclosure are more likely to experience PTSD and drinking problems, improving social support is a novel target for intervention. The proposed study will attempt to prevent the onset of high-risk drinking and PTSD in sexual assault survivors by developing and testing a web-based early intervention aimed at increasing contact with social supporters and mitigating the harm of negative social reactions; ultimately, results will contribute to advancing the field's understanding of the potential for social support to mitigate the harm of trauma.
详细描述
This study involves developing, modifying, and preliminarily testing an intervention to prevent high-risk drinking and PTSD in women who have experienced sexual assault (SA) in the past 10 weeks. In the pilot trial phase of this study, intervention feasibility will be tested in an open trial with N = 40 women with past-10-week SA histories, active drinking, and elevated distress. Participants will complete surveys at baseline, termination, and 3-month follow-up. Participants will be randomized to either the intervention (N = 20) or assessment-only control (N = 20). We hypothesize that (H1) most participants will respond positively on items assessing satisfaction with the intervention, (H2) participants will report above-average usability on a standardized measure, (H3) completion rates for daily activities will be similar to previous web-based interventions, (H4) participants will show significant learning as evidenced by increases in correct responses to knowledge questions from baseline to post, and (H5) participants in the intervention condition will evidence less high-risk drinking and PTSD at 3-month follow-up than participants in the assessment-only condition.

研究组 & 干预措施
Intervention
The THRIVE app involves 3 weeks of daily activities. Day 1 involves identification of activities to add to a "self-care activity list" with guidance around selecting activities that increase social contact, reduce alcohol use, and reduce avoidance. They will also complete an active-learning exercise about cognitive distortions and create a "stuck point to-do list" consisting of their cognitive distortions. In subsequent days, participants will be prompted to complete activities from both lists. They will also have access optional activities on topics such as asking for help, preventing isolation, deciding whether to disclose an assault, coping with negative reactions to disclosure, and thinking in helpful ways about social support. They will be prompted to complete brief daily surveys in the app, which will populate a symptom tracker. Participants in will have brief weekly phone contact with a coach to monitor safety and troubleshoot issues with app use.
干预措施: App-based intervention (Behavioral)
Assessment-only control
The assessment-only control condition will involve access to a version of the app that includes daily surveys and a symptom tracker populated by these surveys, but without any of the other exercises included in the experimental version of the app. Participants in the control condition will have brief weekly phone contact with a coach to monitor safety and troubleshoot issues with app use.
结局指标
主要结局
Posttraumatic Stress Symptom Severity Score at Baseline and 3 Weeks
时间窗: Baseline, post-intervention (3 weeks after baseline)
Sum scores on the Posttraumatic Stress Disorder Checklist for the Diagnostic and Statistical Manual of Mental Disorders-5 (PCL-5), which assesses posttraumatic stress symptom severity. Range: 0-80; higher scores indicate worse outcome.
Posttraumatic Stress Symptom Severity Score at Baseline and 3 Months
时间窗: Baseline, 3 month follow-up
Sum scores on the Posttraumatic Stress Disorder Checklist for the Diagnostic and Statistical Manual of Mental Disorders-5 (PCL-5), which assesses posttraumatic stress symptom severity. Range: 0-80; higher scores indicate worse outcome.
Problem Drinking Scores at Baseline and 3 Months
时间窗: Baseline, 3 month follow-up
Sum scores on Rutgers Alcohol Problem Index- Short Form (RAPI-S), which assesses alcohol use consequences. Range: 0-64; higher scores indicate worse outcome.
