Trauma-focused therapy for refugees: meta-analytic findings

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Refugees globally experience high levels of trauma-related psychological distress.
• Assessing the efficacy of trauma-focused therapies for refugees is critical due to increasing numbers.
• Established psychotherapeutic interventions require evaluation for this vulnerable population.

Purpose of the Study:

• To meta-analyze randomized controlled trials (RCTs) of psychotherapeutic interventions for traumatized adult refugees.
• To determine the efficacy of trauma-focused therapies in reducing symptoms of PTSD and depression.
• To explore potential moderators influencing treatment outcomes.

Main Methods:

• Meta-analysis of 12 studies involving 13 trauma-focused therapies compared to control groups.
• Aggregate effect sizes calculated for posttraumatic stress disorder (PTSD) and depression.
• Metaregression analysis used to identify moderators of PTSD effect size.

Main Results:

• Large aggregate effect size for PTSD (Hedge's g = .91, p < .001) and depression (g = .63, p < .001).
• Number of therapy sessions significantly predicted PTSD effect size magnitude.
• Studies with active control groups showed smaller effect sizes than those with passive controls.

Conclusions:

• Trauma-focused therapy models demonstrate efficacy in treating traumatized adult refugees.
• Treatment duration and control group type are important factors influencing outcomes.
• Further research is needed to optimize interventions for refugee mental health.
