Clinical Trial on the Effectiveness of CETA for Violence and Substance Use in Zambia


Summary

Both intimate partner violence (IPV) and alcohol misuse are highly prevalent and partner alcohol misuse is a significant contributor to women’s risk for IPV. There are few evidence-based interventions to address these in low- and middle-countries (LMIC). We evaluated the effectiveness of an evidence-based, multi-problem, flexible, transdiagnostic intervention, the Common Elements Approach (CETA) in reducing (a) women’s experience of IPV and (b) their male partner’s alcohol misuse among couples in urban Zambia.

This was a single-blind, parallel assignment randomised controlled trial in Lusaka, Zambia. Women who reported moderate or higher levels of IPV and their male partners with hazardous alcohol use were enrolled as a couple and randomized to CETA or treatment-as-usual plus safety checks (TAU-Plus). Primary outcome assessments were planned at post-treatment, 12 months post-baseline, and 24 months post-baseline. IPV was assessed by the Severity of Violence Against Women’s Scale (SVAWS) and male alcohol use by the Alcohol Use Disorders Identification Test (AUDIT). Assessors were blinded. Analyses were intent-to-treat. The trial was registered on ClinicalTrials.gov (NCT02790827).
