In a study published in Psychiatric Services, Burçin Ünlü Ince and colleagues (2014) conducted a meta-analysis to investigate whether and how effective psychotherapy is for racial-ethnic minority groups when they are treated for depression. The study utilized a total of 56 randomized controlled trials. Overall, the effect size was moderate (g=50), and in bivariate and multivariate analysis, race-ethnicity was found to have no moderating influence on outcome of psychotherapy for depression.
The researchers report: "Results suggest that psychotherapy is equally effective regardless of care seekers’ race-ethnicity. Future research should focus on filling in the gap between effective mental health care and the delivery of these services."
