Petersen et al. 2011 | South Africa | Rural | To assess the feasibility of the adapted IPT intervention for women with depressive symptoms that could be delivered by trained lay health workers within a task shifting approach | Grouped-based interpersonal therapy | Non-randomized, intervention | 42 people: 20 intervention; 22 control | Decrease of mean beck depression inventory at 12- and 24-weeks post intervention |
Bolton et al. 2007 | Uganda | Rural | To assess effect of locally feasible interventions on depression, anxiety, and conduct problem symptoms among adolescent survivors of war and displace- ment in northern Uganda | Group interpersonal therapy | Randomized clinical trial | 314 adolescents: 105 randomized to receive creative play; 105 randomized to receive Group IPT and 104 randomized to control group | Substantially and significantly greater decline in the depression symptom scale among the IPT group compared to wait-list control group. Difference in change in adjusted mean score for depression symptoms between group interpersonal psychotherapy and control groups was 9.79 points [95% confidence interval (CI), 1.66–17.93]. This substantial and significant improvement in depression symptoms (12.61 points; 95% CI 2.09–23.14) were found in girls but not in boys receiving group interpersonal psychotherapy |
Verena et al. 2011 | Uganda | Rural | To assess the efficacy of a community-based intervention targeting symptoms of posttraumatic stress disorder (PTSD) in formerly abducted individuals | Narrative exposure therapy | Randomized controlled trial | 85 male and female former children soldier (from 12 to 25 years old) with positive screening result for PTSD | PTSD symptom severity (range: 0–148) was significantly more improved in the narrative exposure therapy group than in the academic catch-up [mean change difference, − 14.06 (95% confidence interval, − 27.19 to − 0.92)] and waiting-list [mean change difference, − 13.04 (95% confidence interval, − 26.79 to 0.72)] groups. Narrative exposure therapy produced a larger within-treatment effect size (Cohen d = 1.80) than academic catch-up (d = 0.83) and wait-listing (d = 0.81) |
Chibanda et al. 2011 | Zimbabwe | Suburban | to gather preliminary data on the effectiveness of this intervention and to see if the intervention would be feasible, and if so to gather ideas about how best to implement it on a larger scale | Brief individual talking therapy based on problem-solving therapy | Non-randomized, intervention | 320 people | After receiving between 3 and 6 sessions the mean score of the SSQ (Shona Symptom Questionnaire) dropped by 4.8 points to 6.5 (sd = 2.4) [t = 13.6 (p = 0.0087)] |
Murray et al. 2013 | Zambia | Urban and peri-urban areas | to evaluate the feasibility of implementing TF-CBT and the changes in trauma-related symptoms with OVC | Trauma focused-cognitive behaviour therapy | Cohort study- prospective | 58 | The average PTSD score after treatment (27.6) was significantly lower than the average pre-treatment score (67.7, p < 0.0001). The effect was similar among males and females. Significant reductions in severity of shame symptoms (p < 0.0001) |
Petersen et al. 2014 | South Africa | peri-urban | to evaluate the potential effectiveness of an adapted group-based HIV counsellor delivered intervention for treating depression in people living with HIV/AIDS | Group-based counseling intervention for depressed co-morbid HIV patient (adapted from group-based IPT) | Randomized controlled pilot study | 76 | Significantly great improvement on depression scores on the PHQ9 in the intervention group compared to the control group at 3-month follow-up (mean difference score of 8.53 in the intervention group compared to mean difference score of 4.12 in the control group at follow-up) [F (1, 32) = 23.88, p < 0.0001]. at post-test, a significant decline in the mean scores on the HSCL-25 (Hopkins Symptoms Checklist) was found for both groups (1.97 and 2.13 for the two groups), [F(1, 32) = 17.48, p < 0.0001] |
Chibanda et al. 2016 | Zimbabwe | Urban | To evaluate the effectiveness of a culturally adapted psychological intervention for common mental disorders delivered by LHWs in primary care | Problem solving therapy | Randomized clinical trials | 573 randomized patients. Woman- 495; 521 completed follow-up at 6 months | Intervention group participants had fewer symptoms than control group participants on Shona Symptoms Questionnaire (SSQ-14) (3.81; 95% CI 3.28 to 4.34; 95% CI 8.33 to 9.47; adjusted mean difference, − 4.86; 95% CI − 5.63 to − 4.10; p < 0.001; adjusted risk ratio, 0.21; 95% CI 0.15 to 0.29; p < 0.001).intervention group participants also had lower risk of symptoms of depression (13.7%; ARR, 0.28; 95% CI 0.22 to 0.34; p < 0.001) |
Bolton et al. 2003 | Uganda | Rural | To test the efficacy of group interpersonal psychotherapy in alleviating depression and dysfunction and to evaluate the feasibility of conducting controlled trials in Africa | Group IPT | Randomized controlled trial | 248 persons. 108 males and 116 females. Refuse 9, others died | decline in depression scores was substantially greater among the intervention groups. Mean changes were 17.47 and 3.55 for the intervention and control groups, respectively (11.59 and 2.38). Within the intervention groups, the mean change among men was 14.43 (95% CI 12.32–16.55) compared with 20.46 (95% CI 18.09–22.84) among women |
Bass et al. 2006 | Uganda | Rural | To assess the long-term effectiveness of Interpersonal Psychotherapy this over a subsequent 6-month period | Group IPT | Randomized controlled trial | 216 | The overall mean functions impairment score was about 4 points lower in the intervention group compared with control group 2 weeks after the intervention and about 5 points 6 months after the intervention (p < 0.0001) |
Munetsi et al. 2018 | Zimbabwe | Urban | To determine whether problem solving therapy delivered by lay health workers can reduce common mental disorder symptoms among people with suicidal ideation, | Problem solving therapy for suicide ideation | Quasi-experimental study | 573 persons | At 6-months severity of common mental disorder symptoms were significantly less among participants whom received LHW Friendship Bench care than among control group. The adjusted mean difference in SSQ-14 score participants with suicidal ideation was-5.38 (95% CI − 7.85, − 2.90; p < 0.001) and among those with common mental disorder symptoms but no suicidal ideation the adjusted mean difference was -4.86 (95% CI − 5.86, -4.04; p < 0.001) |
