mHealth Early Intervention to Reduce Posttraumatic Stress and Alcohol Use After Sexual Assault (THRIVE): Feasibility and Acceptability Results From a Pilot Trial.

BACKGROUND: Sexual assault is associated with increased risk for both posttraumatic stress (PTS) and alcohol misuse. Mobile health interventions have shown promise in addressing PTS and substance use in trauma survivors and might be a promising strategy in extending the reach of early interventions to individuals who have recently experienced trauma. OBJECTIVE: This study assesses the feasibility and acceptability of THRIVE, a mobile health early intervention for recent survivors of sexual assault involving a cognitive behavioral app used daily over 21 days with weekly telephone coaching. METHODS: Twenty adult female survivors of past-10-week sexual assault with elevated PTS and alcohol use were randomized to receive the THRIVE intervention as part of a pilot randomized controlled trial. We sought to understand feasibility by examining rates of completion of intervention activities and testing changes in participants' self-reported knowledge of key intervention concepts from baseline to after the intervention. We assessed acceptability by collecting self-report ratings of satisfaction with the intervention and app usability in a follow-up survey. The coach took notes during coaching calls to track call content and record participant feedback; these notes were qualitatively analyzed to elaborate on the aforementioned domains. RESULTS: Feasibility was demonstrated by moderate rates of activity completion: all participants at least opened the app, 19 (95%) of the 20 participants completed at least 1 cognitive behavioral exercise, and 16 (80%) of the 20 participants attended all 4 coaching calls. Participants completed cognitive behavioral exercises on an average of 10.40 (SD 6.52) out of 21 days. The coaching call notes documented participant comments that app-generated reminders increased completion rates. Feasibility was also demonstrated by the finding that knowledge changes occurred from baseline to after the intervention; this indicated that THRIVE was successful in conveying key concepts. Acceptability was demonstrated by high participant ratings of THRIVE's usability; the ratings corresponded to a B+ usability grade. The coaching call notes documented that usability was increased by the coaching calls, the app exercises' clarity, and the app exercises' inclusion of suggestions; however, the coaching call notes also documented that some of the participants found aspects of the app exercises to be difficult or confusing. Acceptability was also demonstrated by participant ratings of satisfaction: most of the participants (15/16, 94%) rated the app as either moderately helpful or very helpful. The coaching call notes documented that the cognitive behavioral activity modules were seen as appealing and that the positive impact of the intervention contributed to participants' satisfaction. CONCLUSIONS: These findings suggest that THRIVE is feasible and acceptable to survivors of recent sexual assault and that further testing of THRIVE is warranted.

Pilot randomized clinical trial of an app-based early intervention to reduce PTSD and alcohol use following sexual assault.

OBJECTIVE: Sexual assault is associated with high risk for posttraumatic stress disorder (PTSD), and PTSD often co-occurs with alcohol misuse. Most sexual assault survivors do not access early preventative interventions for such conditions. App-based interventions are a promising means to extend the reach of early interventions and thereby reduce risk of chronic PTSD and alcohol misuse. METHOD: This study was a pilot randomized clinical trial of an app-based early intervention with phone coaching (THRIVE) for survivors of past-10-week sexual assault (NCT#: NCT03703258). Intended active components of the THRIVE app are daily cognitive restructuring, daily activity scheduling, and as-needed relationally focused exercises, supported by coaching calls. Forty-one adult female survivors of recent sexual assault with elevated posttraumatic stress and drinking were randomized to intervention or control (symptom-monitoring app with phone coaching). Participants in both conditions were encouraged to use their respective app for 21 days and completed self-report symptom assessments at baseline, postintervention, and 3-month follow-up. RESULTS: At 3-month follow-up, the between-group effect size favored intervention for posttraumatic stress (d = -0.70), intoxication frequency (d = -0.62), and drinking hours per week (d = -0.39). More participants evidenced reliable change in intervention versus control for posttraumatic stress (OR = 2.67) and alcohol problems (OR = 3.05) at 3 months. CONCLUSIONS: The general direction of effects indicates that THRIVE, coupled with coaching, reduces risk for PTSD and alcohol outcomes beyond coached monitoring. These findings suggest that apps like THRIVE may provide an option for early intervention for sexual assault survivors. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Social Network Changes and Disclosure Responses after Sexual Assault.

Social support after sexual assault is important for recovery, but violence and recovery may also challenge relationships. We examined functional and structural social support changes following sexual assault and their association with mental health. College women (N=544) with and without a sexual assault history completed a cross-sectional survey assessing current and past egocentric social networks. Functional support (perceived global support, assault disclosure, perceived helpfulness of responses) and structural support (network density, size, retention) were examined. Multilevel models revealed that, relative to non-survivors, survivors reported smaller, less dense past networks, but similarly sized current networks. Survivors retained less of their networks than non-survivors, and network members who provided unhelpful responses to disclosure were less likely to be retained. Structural equation modeling revealed that, among survivors, perceived unhelpful responses to disclosure and a greater loss of network members were associated with worse mental health. Findings suggest that survivors may experience a restructuring of social networks following sexual assault, especially when network members respond in unhelpful ways to disclosure. Although survivors appeared to build new relationships, this restructuring was associated with more mental health problems. It is possible that interventions to improve post-assault social network retention may facilitate recovery.

A Systematic Review of the Balloon Analogue Risk Task (BART) in Alcohol Research.

Risk-taking propensity has been crucial to the investigation of alcohol use and consequences. One measure, the balloon analogue risk task (BART), has been used consistently over the past two decades. However, it is unclear how this measure is related to alcohol outcomes. This paper systematically reviews the literature on the BART and alcohol outcomes. First, direct associations between the BART and alcohol use are reviewed including correlations, group comparisons, the BART's prediction of alcohol outcomes and BART performance after consuming alcohol. Then, potential moderators that explain when and for whom the BART is related to alcohol outcomes are reviewed. Finally, potential mechanisms that explain how the BART and alcohol outcomes are related are reviewed. This review reveals patterns in the BART suggesting risk-taking propensity may be related to changes in alcohol use over time; however, there is little evidence to suggest BART scores increase after consuming alcohol. Yet, additional research suggests adjusted average pump scores may be too simplistic for the amount of information the BART captures and understanding individual's patterns of responses on the BART is important for investigating its relation to alcohol outcomes. Finally, this review opens up several future directions for research to understand how risk-taking propensity is related to alcohol outcomes.
