Project Summary/Abstract Research documents the concerning rates and negative outcomes of adverse childhood experiences (ACEs). To date, we know very little about two-generation programs that may simultaneously prevent ACEs among children including intimate partner violence (IPV) among their caregivers. The proposed project addresses objective 3 of NICIPC’s initiative, evaluation of strategies that incorporate a dual generation approach to break the cycle of violence and adversity. The project purpose is to test the impact of a widely researched alcohol and drug abuse prevention program, the Strengthening Families Program (SFP), on reducing ACEs in children (10-14) including child abuse and IPV among their caregivers (primary outcomes). Guided by social learning and ecological theories that empathize the importance of the proximal family environment, the members of this multi-stakeholder collaborative believe that the SFP has the strong potential to be effective in reducing IPV in caregivers and additional ACEs in their children given that the SFP focuses on reducing myriad risk and protective factors for not only drug use, but for ACEs, including IPV and child abuse. As part of this project and in order to bolster the program’s effectiveness, we will adapt the SFP (renamed for this project: Was’ake Tiwahe, Lakota for “strong families”) to include additional evidence-based IPV prevention strategies (e.g., economic empowerment) for adults and peer-to-peer violence prevention strategies (e.g., bystander intervention) for youth in addition to cultural adaptations given the large presence of American Indians in Rapid City, SD, where this project will take place. During the Adaptation and Planning Phase (Year 1), first the team will convene a Research and Practice Advisory Board and conduct focus groups to adapt the program. Next, the team will conduct an open pilot trial of the adapted program and engage youth and caretakers in cognitive testing of survey instruments to be used in the subsequent clinical trial. During the Outcome and Process Evaluation Phase (Years 2 and 3), the team will implement and evaluate the feasibly and acceptably of the Was’ake Tiwahe via program observations and fidelity checks, key informant interviews, and Photovoice. In addition to the in-depth process evaluation, the team will gather efficacy data by randomly assigning higher risk families, i.e., American Indian and/or low income (N=320 enrolled and randomized), to a wait-list control or treatment conditions. Pre-, immediate post-, and 8-month follow-up surveys will test for reductions in ACEs in youth (N=320), including reductions in IPV in their caregivers (N=320). With exploratory analyses, the team will identify mediators (e.g., increases in adult supervision, economic empowerment) and moderators (e.g., gender) of program outcomes. Finally, during the Revision and Dissemination Phase (Year 3), the team will use data collected in prior phases to revise the program. T...
