TURNER, William et al. Methodological challenges in group-based randomised controlled trials for intimate partner violence perpetrators: a meta-summary. Psychosocial Intervention [online]. 2023, vol.32, n.2, pp.123-136.  Epub Nov 27, 2023. ISSN 2173-4712.  https://dx.doi.org/10.5093/pi2023a9.

Evidence for treatment effects of group-based Intimate Partner Violence (IPV) perpetrators programmes remains, at best, inconclusive. In the present review, systematic/meta-analytic reviews were used to identify randomised controlled trials and a meta-summary approach was employed to identify methodological challenges in the design and conduct of these trials. Of the fifteen studies identified, seven were comparative effectiveness trials. A range of methodological challenges were also identified by the trialists; source of outcome data, treatment modality, attrition and sample characteristics were the most frequently mentioned. Although there are only a few randomised controlled trials compared to non randomised studies, the findings of both highlight the need to invest in the development of innovative and/or combined IPV treatment programmes to address co-occurring issues such as substance use and trauma. The summary of methodological challenges will provide the first step in the development of methods guidance for researchers working in this area.
