A systematic review included ten experimental or quasi-experimental studies. Of these, six showed positive impacts on intimate partner violence; one study found promising results; and three reviews found no impact. It should be noted that these ten evaluations covered short-, medium-, and long-term programs, with some programs including two therapy sessions and others up to 40 sessions. [1]
A systematic review and meta-analysis of six experimental studies on interventions with couples carried out in the United States included 470 participants and also indicated that couple therapy sessions significantly reduce intimate partner violence. Three of the programs included use methodologies of 1:1 behavioral therapy sessions for couples; one program offers 1:1 or group sessions focused on developing healthy relationships; another offers 1:1 therapy sessions focused on domestic violence; and a final one works on aggressive behaviors in group sessions with couples.
