Input: Six trials, all from the USA, involving 2343 participants, were included. A meta-analysis of four trials comparing CBT with a no-intervention control (1771 participants) reported that the relative risk of violence was 0.86 (favouring the intervention group) with a 95% confidence interval (CI) of 0.54 to 1.38. This is a small effect size, and the width of the CI suggests no clear evidence for an effect. One study (Wisconsin Study) compared CBT with process-psychodynamic group treatment and reported a relative risk of new violence of 1.07 (95% CI 0.68 to 1.68). Even though the process-psychodynamic treatment did marginally better than CBT, this result is equivocal. Finally, one small study (N = 64) compared a combined CBT treatment for substance abuse and domestic violence (SADV) with a Twelve-Step Facilitation (TSF) group. An analysis involving 58 participants investigated the effect on reduction in frequency of physical violence episodes. The effect size was 0.30 (favouring TSF) with 95% CI from -0.22 to 0.81. There are still too few randomised controlled trials to draw conclusions about the effectiveness of cognitive behaviour therapy for male perpetrators of domestic violence.
Output:

We included trials that involved both types of participants. The review found all randomised controlled evaluations of the effects of CBT on men's physical violence to their female partners worldwide, but there were only six small trials with a total of 2343 participants that met the inclusion criteria. The results of four of these trials, which compared men who received CBT with men getting no treatment, were combined. This was not able to show us whether or not CBT was better than no treatment. Similarly, the individual results of the other two trials, which compared CBT with another treatment, were inconclusive. Overall, the evidence from the included studies is insufficient to draw any conclusions.
