Group interpersonal psychotherapy for depression in rural Uganda: 6-month outcomes - Randomised controlled trial
ABSTRACT A randomised controlled trial comparing group interpersonal psychotherapy with treatment as usual among rural Ugandans meeting symptom and functional impairment criteria for DSM-IV major depressive disorder or sub-threshold disorder showed evidence of effectiveness immediately following the intervention.
To assess the long-term effectiveness of this therapy over a subsequent 6-month period.
A follow-up study of trial participants was conducted in which the primary outcomes were depression diagnosis, depressive symptoms and functional impairment.
At 6 months, participants receiving the group interpersonal psychotherapy had mean depression symptom and functional impairment scores respectively 14.0 points (95% CI 12.2-15.8; P<0.0001) and 5.0 points (95% CI 3.6-6.4; P<0.0001) lower than the control group. Similarly, the rate of major depression among those in the treatment arm (11.7%) was significantly lower than that in the control arm (54.9%) (P<0.0001).
Participation in a 16-week group interpersonal psychotherapy intervention continued to confer a substantial mental health benefit 6 months after conclusion of the formal intervention.

ABSTRACT: Background Experiencing systematic violence and trauma increases the risk of poor mental health outcomes; few interventions for these types of exposures have been evaluated in low resource contexts. The objective of this randomized controlled trial was to assess the effectiveness of two psychotherapeutic interventions, Behavioral Activation Treatment for Depression (BATD) and Cognitive Processing Therapy (CPT), in reducing depression symptoms using a locally adapted and validated version of the Hopkins Symptom Checklist and dysfunction measured with a locally developed scale. Secondary outcomes included posttraumatic stress, anxiety, and traumatic grief symptoms.Methods Twenty community mental health workers, working in rural health clinics, were randomly assigned to training in one of the two interventions. The community mental health workers conducted baseline assessments, enrolled survivors of systematic violence based on severity of depression symptoms, and randomly assigned them to treatment or waitlist-control. Blinded community mental health workers conducted post-intervention assessments on average five months later.ResultsAdult survivors of systematic violence were screened (N¿=¿732) with 281 enrolled in the trial; 215 randomized to an intervention (114 to BATD; 101 to CPT) and 66 to waitlist-control (33 to BATD; 33 to CPT). Nearly 70% (n¿=¿149) of the intervention participants completed treatment and post-intervention assessments; 53 (80%) waitlist-controls completed post-intervention assessments. Estimated effect sizes for depression and dysfunction were 0.60 and 0.55 respectively, comparing BATD participants to all controls and 0.84 and 0.79 respectively, compared to BATD controls only. Estimated effect sizes for depression and dysfunction were 0.70 and 0.90 respectively comparing CPT participants to all controls and 0.44 and 0.63 respectively compared to CPT controls only. Using a permutation-based hypothesis test that is robust to the model assumptions implicit in regression models, BATD had significant effects on depression (p¿=¿.003) and dysfunction (p¿=¿.007), while CPT had a significant effect on dysfunction only (p¿=¿.004).Conclusions Both interventions showed moderate to strong effects on most outcomes. This study demonstrates effectiveness of these interventions in low resource environments by mental health workers with limited prior experience.Trial RegistrationClinicalTrials.Gov NCT00925262.
