Effectiveness of Group Problem Management Plus Among Individuals Experiencing Psychological Distress: A Systematic Review and Meta-Analysis.

Purpose: To assess the impact of Group Problem Management Plus (Group PM+) as an intervention for individuals experiencing psychological distress.

Method: The current study was a systematic review and meta-analysis. Multiple databases were searched electronically between June 2015 and June 2024 for randomized controlled trials (RCTs) evaluating the effectiveness of Group PM+ for people experiencing psychological distress.

Results: Nine research studies (N = 1,913 patients) were included. Group PM+ improved physical functioning (standardized mean difference [SMD] = -2.39, 95% confidence interval [CI] [-4.05, -0.72]; p < 0.01) and reduced negative emotions (SMD = -1.08, 95% CI [-1.72, -0.44]; p < 0.01). However, there were no statistically significant improvements in social-interpersonal level (SMD = 0.46, 95% CI [-0.80, 1.73]; p = 0.47) or reduction of antecedent and posttraumatic disorders (SMD = -0.07, 95% CI [-0.68, 0.54]; p = 0.82).

Conclusion: For people who experience psychological distress, Group PM+ helps improve physical functioning and minimize negative emotions. Yet, it is undetermined whether the intervention enhances social interpersonal levels and diminishes antecedent and posttraumatic disorders. A more robust RCT should be performed in the future that will verify the efficacy of Group PM+ for individuals experiencing psychological distress.
