The Strength at Home Couples program is designed to enhance intimate relationships and prevent intimate partner violence (IPV) among service members and their partners in light of the unique stressors and experiences of this population.
A Hybrid Type-I Implementation-effectiveness research design will allow the research team, comprising investigators with expertise in treatment development, efficacy and effectiveness research, and implementation science, to simultaneously investigate the effectiveness of SAH-C in a military population while identifying any barriers to implementation that would need to be addressed before SAH-C could be successfully implemented on a larger scale. SAH-C derives from a unique fusion of interventions for trauma and IPA, integrating elements of cognitive processing therapy for PTSD,39 couples therapy for PTSD,40 and a cognitive behavioral intervention for IPA.41 SAH-C consists of 10 two-hour weekly sessions, co-led by two therapists. This was the minimum length deemed necessary to incorporate components addressing the proposed IPA mechanisms and is consistent with the briefest IPA interventions.42 During each session, couples are provided assignments to practice skills together and to assist with the consolidation of material. A group couples format is used because group cohesion among clients appears to be associated with IPA prevention.43 Group interventions also use less time and resources than individual-based interventions.

Changes in suicidal ideation through the suicidality measure asking about suicidal thoughts (the four response options include: I do not have thoughts, Sometimes I have thoughts, Most of the time I have thoughts, and I always have thoughts), suicide attempts (response is a fill in the blank), wish to live/die (the three response options include I have a moderate to strong wish to live/die, I have a weak wish to live/die, and I have no wish to live/die), and belongingness (some items will be reverse scored and the 7-point Likert scale includes 1\[Not at all true for me\], 2, 3, 4 \[Somewhat true for me\], 5, 6, 7 \[Very true for me\]). Lower scores indicate less suicidal ideation.
