Abstract

ARIAS, Esther; ARCE, Ramón  and  VILARINOA, Manuel. Batterer intervention programmes: a meta-analytic review of effectiveness. Psychosocial Intervention [online]. 2013, vol.22, n.2, pp.153-160. ISSN 2173-4712.  http://dx.doi.org/10.5093/in2013a18.

A meta-analysis of the state-of-the-art on the efficacy of batterer treatment programmes was conducted from the year 1975 to 2013. A total of 19 Spanish and English language research articles were retrieved yielding 49 effect sizes from a sample of 18,941 batterers. The results revealed that the recidivism rate as measured by couple reports (CR) was significantly higher than the rate based on official reports (OR), since the recidivism as measured by OR is underestimated. Overall, treatment showed a non significant positive weighted mean effect, δ = 0.41. Nevertheless, the counternull effect size, EScounternull =0.82, suggested a null effect was as probable as a treatment efficacy rate of 38%. The intervention type was not a significant moderator of recidivism, but the counternull effect sizes, EScounternull = 0.82 and 0.94, revealed an efficacy rate of 38% and 42% based on ORs, for Duluth Model and behavioral-cognitive treatment, respectively. The long-term treatment interventions had a significantly positive medium effect size, δ = 0.49. The implications of these findings for the design and assessment of future intervention programmes are discussed.
