A mixed-methods approach will be used for this single site, parallel group RCT. All participants will be randomized at the individual level to Strength at Home (SAH) or Treatment as Usual (TAU), with a 1:1 allocation ratio. Assessments will occur pre-treatment and post-treatment with follow-up assessments scheduled every three months post-treatment through month 12. Assessments have been designed to examine reductions in IPV and other outcomes including posttraumatic stress disorder (PTSD) symptoms and alcohol use.
The primary hypotheses are that those receiving SAH will evidence greater reductions in physical and psychological IPV, symptoms of PTSD, alexithymia, and alcohol use problems, and higher treatment satisfaction relative to those receiving TAU across the time points.
The specific aims and sub aims are:
1. Test the comparative effectiveness of SAH and TAU by conducting an RCT comparing 200 justice-involved men randomly assigned to each program.
* Compare the frequency of physical and psychological IPV, the primary outcomes of interest, across conditions as reported by the male participants and their intimate partners across Time 1 (baseline) and four 3-month follow ups (Times 2-5). Additionally, at Time 5, the study may make use of available arrest record data from the state of Rhode Island.
* Compare symptoms of PTSD, alexithymia, and alcohol use problems across conditions and assessment time points as reported by the male participants.
* Compare treatment satisfaction across conditions as reported by the male participants across the four 3-month follow ups (Times 2-5).
2. Facilitate future use of SAH by working closely with the Stakeholder Advisory Board to identify potential barriers and facilitators to successful implementation in civilian community settings.
* Identify barriers and facilitators to implementation.
* Assess the acceptability of SAH among stakeholders in the community setting and areas in need of refinement.
