Brief summary: The purpose of the project is to develop and test a couples-based relationship enhancement group intervention for married or partnered Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF)/Operation New Dawn (OND) veterans to prevent the perpetration of intimate partner aggression (IPA) among participants.

Detailed description: The focus of this project is to produce a well-defined and standardized intervention, labeled Strength at Home Couples Group, that can improve intimate relationship satisfaction, decrease the likelihood of relationship aggression, increase the intimacy and closeness of the relationship, and help with anger management. We hope to learn more about how to improve relationships, how to prevent anger and violence, and about what factors help people successfully complete treatment. Strength at Home Couples Group will incorporate components of several interventions for PTSD and IPA and will target mechanisms implicated in the PTSD-IPA association. The development of this type of integrated intervention is critical due to high rates of PTSD-IPA co-occurrence and the pressing need to efficiently address both problems among military veterans. Specific aims of this project are: (1) to develop and standardize Strength at Home Couples Group for male combat veterans, including the development of a clinician-friendly intervention manual detailing Strength at Home Couples Group, along with intervention adherence measures and therapist training and certification procedures; (2) to test the efficacy of Strength at Home Couples Group for OEF/OIF/OND veterans by conducting a multiple site randomized trial comparing 10 sessions of Strength at Home Couples Group to 10 sessions of a supportive group therapy (ST) condition; and (3) to explore differences in compliance and process factors across conditions.

Eligibility criteria: Inclusion Criteria:

* couples must have been in a committed relationship for at least six months
* veterans and their partners must be over the age of 18
* male members of the couple report no occurrence of physical aggression during the last six months in their current relationship on the Revised Conflict Tactics Scale (CTS2; Straus et al, 1996)

* one partner of the couple averages at or below a score of 29 on the 6-item Quality of Marriage Index (QMI; Norton, 1983) or a 100 or below on the Dyadic Adjustment Score (DAS; Spanier, 1976), which are cutoff scores often used to distinguish distressed and non-distressed couples (e.g., Slep, Heyman, Williams, Van Dyke, \& O'Leary, 2006), or one member of the couple endorses veteran-perpetrated psychological aggression (defined as scoring above the 75%ile on the CTS2 minor psychological aggression subscale, or any endorsement of items on the severe psychological aggression subscale on the CTS2 or the Dominance/Intimidation scale of the Multidimensional Measure of Emotional Abuse, MMEA; Murphy \& Hoover, 1999;)
* both members of the couple provide research consent

Exclusion Criteria:

* reading difficulties prevent valid completion of the assessment instruments
* the participant evidences severe organicity or active psychosis
* the participant expresses prominent suicidal or homicidal ideation
* the participant meets diagnostic criteria for alcohol and/or drug dependence, if not in early full remission or sustained partial remission
* female members of the couple report their violence includes the use of weapons during the past six months in their current relationship on the Revised Conflict Tactics Scale (CTS2; Straus et al., 1996)
* violence perpetrated by female members of the couple produces injuries in men
* male members of the couple indicate they are fearful of the female partner
* male members of the couple report they are physically violent in any way during the past six months or severely violent in the past 12 months of their current relationship on the Revised Conflict Tactics Scale (CTS2; Straus et al., 1996)
* male members of the couple have had any bruising or injuries inflicted by the female partner during the past six months in their current relationship. Criteria b through d will be assessed using the Mini-International Neuropsychiatric Interview (MINI; Sheehan et al., 1998) and clinical interview

Primary outcomes:
measure: Evidence of change in incidence and frequency of intimate partner physical assault and psychological aggression assessed by questionnaires and clinical interviews.
timeFrame: Change determined by assessments pre and post treatment, 6 months, 12 months, and 18 months following treatment
Secondary outcomes:
measure: Evidence of change in risk factors (i.e. PTSD symptoms, anger, relationship satisfaction) implicated in the development of IPA assessed by questionnaires, clinical interviews, and psychophysiological measurements.
timeFrame: Change determined by assessments pre and post treatment, 6 months, 12 months, and 18 months following treatment
