Psychosocial Interventions for Prisoners with Mental and Substance Use Disorders: A Systematic Review.

The 21 studies included in the review had a sample size of 34 to 759. The settings of all the interventions were the prison and different types of psychosocial interventions were provided across the studies. The average duration of intervention ranged between 10 min and 120 min with the frequency of one to six sessions per week for 1 to 36 months. All the 21 Randomized Control Trials (RCTs) were nonIndian studies. Overall, the results of the included studies showed significant improvement postintervention (motivational intervention, interpersonal therapy, cognitive behavior therapy, positive psychology intervention, music therapy, and acceptance and commitment therapy) on primary outcome measures such as symptom severity of depression, anxiety, and substance abuse prisoners. Positive effects were observed on secondary outcome measures such as motivation, aggression, follow up rates, and recidivism. A limited number of studies have focused on evaluating psychosocial interventions in prison settings. Most of the interventions were tested in prisoners with substance use disorder alone or in those with dual diagnoses and in high-income countries.
