This literature search analyzed the impact of research into interventions on episodes of relationship violence and on attitudes, behaviors, and skills related to relationship violence.
The authors searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, PsycINFO, six other databases and a trials register on 7 May 2012. They hand searched the references lists of key articles and two journals (Journal of Interpersonal Violence and Child Abuse and Neglect) and contacted researchers in the field. Studies included in this review showed no evidence of effectiveness of interventions on episodes of relationship violence or on attitudes, behaviors and skills related to relationship violence. The authors found a small increase in knowledge, but there was evidence of substantial heterogeneity among studies. Further studies with longer‐term follow‐up are required, and study authors should use standardized and validated measurement instruments to maximize comparability of results.
