High prevalence of PTSD in incarcerated forensic populations indicates the need for effective treatment. Little is known about the efficacy of current methods and the status of the quality of available research in this developing research area. Goal of current study is to create an overview of study quality and insights in combined efficacy of available studies. Eligibility criteria: Only Randomised Controlled Trials (RCT’s) that investigated psychological of psychotherapeutic interventions aimed at treating PTSD symptoms in incarcerated forensic populations were included. 

Broad population and intervention inclusion criteria were adhered. Strict methodological criteria were adhered. Methods: By means of meta-analysis a combined effect sizes was synthesized. Quality assessments and Cochrane risk of bias analyses were performed. Results: A total of eleven studies were included in statistical analysis, encompassing a total N of 814. Small to medium combined effect sizes were synthesized. Conclusions: Research on the efficacy of PTSD treatment in forensic populations is limited in both quantity and quality. Randomised controlled trials of first choice interventions, with big sample sizes, are recommended.
