Evaluating Interventions for Intimate Partner Violence Use in Washington State
This study is looking at ways to reduce intimate partner violence (IPV), which is physical or emotional harm from a partner. Many people are required by court to attend programs for IPV, but we don't have much information on how well these programs work. This study will compare a program called Strength at Home (SAH) to the usual court-mandated programs in Washington State. SAH is a group program that meets for 20 two-hour sessions each week. The study wants to see if SAH is as good as, or better than, the usual programs at reducing IPV. We will measure IPV, psychological IPV, and symptoms of Post Traumatic Stress Disorder (PTSD) over 12 months. Men who are court-referred for IPV intervention and their current or former female partners can join this study. The study aims to enroll 800 participants.

What this trial measures
- IPV assessmentBaseline, 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 assessmentBaseline, 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) symptomsBaseline, 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 useBaseline, 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 assessmentBaseline, 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.
