Overview
Brief Summary
Intimate partner violence (IPV), specifically physical and psychological aggression toward an intimate partner, represents a public health crisis that affects millions of Americans each year. There currently exists very little evidence from randomized controlled trials for the effectiveness of abuser intervention programs designed to prevent and end perpetration of IPV in the general population. This is troubling considering that approximately half a million men and women are court-mandated to these programs each year.
The investigators will conduct a randomized control trial (RCT) investigating the efficacy of the Strength at Home (SAH) intervention in reducing intimate partner violence (IPV). The overarching aim of this study is to test the efficacy of SAH with court-involved-partner-violent men through an RCT comparing those who receive SAH with those who receive other standard IPV interventions offered in the state of Washington (treatment as usual- TAU).
The specific aims are:
1.1: 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). It is expected that greater reductions in IPV frequencies will be evidenced in SAH than TAU over the course of the year.
1.2: Compare symptoms of PTSD, alexithymia, and alcohol use problems across conditions and assessment time points as reported by the male participants. It is expected that greater reductions in these symptoms will be evidenced in SAH than TAU over the course of the year.
1.3: Compare treatment satisfaction across conditions as reported by the male participants across the four 3-month follow ups (Times 2-5). It is expected that treatment satisfaction will be higher in SAH than TAU.

Outcomes
Primary Outcomes
IPV assessment
Time Frame: Baseline, 3 months, 6 months. 9 months, 12 months
The revised Conflict Tactics Scales (CTS2), a 20-item instrument, will be used to assess IPV. The Physical Assault (12 items) and Psychological Aggression (8 items) subscales will be administered. Each of the 20 items is scored by the frequency of occurrence of the item with 8 choices 1-7 and 0.
Psychological IPV assessment
Time Frame: Baseline, 3 months, 6 months. 9 months, 12 months
The 7-item Restrictive Engulfment subscale of the Multidimensional Measure of Emotional Abuse (MMEA) will be used as an additional measure of psychological IPV. Each item has 7 potential responses from 0=never to 6= more than 20 times. Scores can range from 0 to 42, with higher scores being associated with more psychological IPV.
Post Traumatic Stress Disorder (PTSD) symptoms
Time Frame: Baseline, 3 months, 6 months. 9 months, 12 months
The 20-item PTSD Checklist for DSM 5 (PCL-5) will be used to assess PTSD symptoms. It is a self-report measure. Items are rated on a 5-point Likert scale \[0 to 4\] and summed. Scores range from 0 to 80 with higher scores associated with more PTSD symptoms. A total score of 33 or higher may indicate severe PTSD.
Alcohol use
Time Frame: Baseline, 3 months, 6 months. 9 months, 12 months
The 10-item Alcohol Use Disorders Identification Test (AUDIT) will be used to assess problem drinking behavior over the past six months, with higher scores reflecting greater alcohol misuse.
Alexithymia assessment
Time Frame: Baseline, 3 months, 6 months. 9 months, 12 months
The 20-itemToronto Alexithymia Scale (TAS-20) will be used to assess alexithymia. The TAS-20 uses cutoff scoring, with scores of 52-60 indicating possible alexithymia, and scores above 60 indicating alexithymia.
Secondary Outcomes
- Treatment Satisfaction(3 months, 6 months. 9 months, 12 months)
