Effect of a brief psychological intervention for common mental disorders on HIV viral suppression: A non-randomised controlled study of the Friendship Bench in Zimbabwe.

BACKGROUND: For people living with co-morbid HIV and common mental disorders (CMD), it is not known whether a brief psychological intervention for CMD can improve HIV viral suppression. METHODS: We conducted a prospective cohort study in eight primary care clinics in Harare, Zimbabwe, enrolling adults with co-morbid HIV and CMD. Six clinics provided the Friendship Bench (FB), a brief psychological intervention for CMD based on problem-solving therapy, delivered by lay counsellors. Two clinics provided enhanced usual care (EUC). The primary outcome was viral non-suppression after six months (viral load ≥400 copies/mL). Data were analysed using a difference-in-difference approach with linear regression of cluster-level proportions, adjusted for baseline viral non-suppression (aDiD). The secondary outcome was presence of CMD measured by the Shona Symptom Questionnaire. RESULTS: In FB clinics, 407/500 (81.4%) participants had viral load results at baseline and endline: 58 (14.3%) had viral non-suppression at baseline and 41 (10.1%) at endline. In EUC clinics, 172/200 (86.0%) had viral load results at baseline and endline: 22 (12.8%) were non-suppressed at baseline and 26 (15.1%) at endline (aDiD = -7.3%; 95%CI 14.7% to -0.01%; p = 0.05). Of the 499 participants virally suppressed at baseline, the FB group had lower prevalence of non-suppression at endline compared to the EUC group (2.9% vs 9.3%; p = 0.002). There was no evidence of a difference in endline viral non-suppression by group among the 80 participants with non-suppression at baseline (53.5% vs 54.6%; p = 0.93). The FB group was less likely to screen positive for CMD at endline than the EUC group (aDiD = -21.6%; 95%CI -36.5% to -6.7%; p = 0.008). CONCLUSION: People living with co-morbid HIV and CMD may benefit from receiving a low-cost mental health intervention to enhance viral suppression, especially if they are already virally suppressed. Research is needed to understand if additional adherence counselling could further improve viral suppression.

Interventions for adolescents and adults with psychosis in Africa: a systematic review and narrative synthesis.

Background: The Global Burden of Disease attributable to psychotic disorders in African countries is high and has increased sharply in recent years. Yet, there is a scarcity of evidence on effective, appropriate and acceptable interventions for schizophrenia and other psychotic disorders on the continent. Methods: We carried out a systematic review and narrative synthesis of peer-reviewed literature evaluating the impact of non-pharmacological interventions for adolescents and adults (10-65 years) in African countries. Two reviewers independently double-screened all articles and performed data extraction and quality appraisal using standardized tools. Results: Of the 8529 unique texts returned by our search, 12 studies were identified for inclusion, from seven countries: Egypt, Ethiopia, Ghana, Kenya, Nigeria, South Africa and Sudan. They evaluated a range of interventions with one or more clinical, psychological or psychosocial, education or awareness or traditional or faith-based components, and were delivered by either mental health specialists or non-specialist health workers. Ten of the 12 included studies reported significant, positive effects on a range of outcomes (including functioning, symptoms and stigma). Nearly half of the interventions were based out of health facilities. Based on quality appraisals, confidence in these studies' findings is only rated low to medium. Conclusion: Further research is needed to develop and evaluate interventions that meet the diverse needs of people with psychosis, within and beyond the health sector.

The Friendship Bench as a brief psychological intervention with peer support in rural Zimbabwean women: a mixed methods pilot evaluation.

BACKGROUND: There is a large treatment gap for common mental disorders in rural areas of low-income countries. We tested the Friendship Bench as a brief psychological intervention delivered by village health workers (VHWs) in rural Zimbabwe. METHODS: Rural women identified with depression in a previous trial received weekly home-based problem-solving therapy from VHWs for 6 weeks, and joined a peer-support group. Depression was assessed using the Edinburgh Postnatal Depression Scale (EPDS) and Shona Symptom Questionnaire (SSQ). Acceptability was explored through in-depth interviews and focus group discussions. The proportion of women with depression pre- and post-intervention was compared using McNemar's test. RESULTS: Ten VHWs delivered problem-solving therapy to 27 women of mean age 33 years; 25 completed six sessions. Women valued an established and trustful relationship with their VHW, which ensured confidentiality and prevented gossip, and reported finding individual problem-solving therapy beneficial. Peer-support meetings provided space to share problems, solutions and skills. The proportion of women with depression or suicidal ideation on the EPDS declined from 68% to 12% [difference 56% (95% confidence interval (CI) 27.0-85.0); p = 0.001], and the proportion scoring high (>7) on the SSQ declined from 52% to 4% [difference 48% (95% CI 24.4-71.6); p < 0.001] after the 6-week intervention. CONCLUSION: VHW-delivered problem-solving therapy and peer-support was acceptable and showed promising results in this pilot evaluation, leading to quantitative and qualitative improvements in mental health among rural Zimbabwean women. Scale-up of the Friendship Bench in rural areas would help close the treatment gap for common mental disorders.

Impact of Friendship Bench problem-solving therapy on adherence to ART in young people living with HIV in Zimbabwe: A qualitative study.

BACKGROUND: Adolescents and young people globally are highly vulnerable to poor mental health especially depression, and they account for 36% of new HIV infections in Eastern and Southern Africa. HIV services remain inadequate for this population and their adherence to ART is low. The Friendship Bench (FB), an evidence-based model developed in Zimbabwe to bridge the mental health gap, is a brief psychological intervention delivered on benches in primary care facilities by lay health workers ("grandmothers") trained in problem-solving therapy. This study explored the experience of young people living with HIV attending FB, and their perception of how problem-solving therapy impacted their adherence to ART. METHODS: Semi-structured interviews were conducted in July 2019 with 10 young people living with HIV aged 18-24 years, who had recently completed FB counselling in Harare. Participants were purposively sampled and recruited from three primary care facilities. Interviews were conducted in Shona, audio-recorded, transcribed verbatim and translated into English. Transcripts were analysed in NVivo12 using inductive thematic analysis. RESULTS: Study findings revealed a clear emotional denial towards HIV, particularly for young people infected perinatally, and a resulting low adherence to ART. The study also unpacked the issues of internal stigma and how young people living with perinatally acquired HIV are informed of their HIV status. Participants reported that FB had a critical role in helping them accept their HIV status. Grandmothers' empathic attitude was key during counselling on adherence to ART, to demystify the disease and treatment, normalize the reality of living with HIV, encourage young people to socialize with peers and free them of guilt. Interviewees unanimously reported improved ART adherence following FB counselling, and many described enhanced health and wellbeing. CONCLUSION: Participants saw FB as a strong contributor to their general well-being, evident in decreased symptoms of depression and improved adherence to ART. FB problem-solving therapy should be rolled out to further support young people after post-test counselling or HIV serostatus disclosure for perinatally acquired HIV, for acceptance of HIV status and adherence to ART.

Effect of a Primary Care-Based Psychological Intervention on Symptoms of Common Mental Disorders in Zimbabwe: A Randomized Clinical Trial.

Importance: Depression and anxiety are common mental disorders globally but are rarely recognized or treated in low-income settings. Task-shifting of mental health care to lay health workers (LHWs) might decrease the treatment gap. Objective: To evaluate the effectiveness of a culturally adapted psychological intervention for common mental disorders delivered by LHWs in primary care. Design, Setting, and Participants: Cluster randomized clinical trial with 6 months' follow-up conducted from September 1, 2014, to May 25, 2015, in Harare, Zimbabwe. Twenty-four clinics were randomized 1:1 to the intervention or enhanced usual care (control). Participants were clinic attenders 18 years or older who screened positive for common mental disorders on the locally validated Shona Symptom Questionnaire (SSQ-14). Interventions: The Friendship Bench intervention comprised 6 sessions of individual problem-solving therapy delivered by trained, supervised LHWs plus an optional 6-session peer support program. The control group received standard care plus information, education, and support on common mental disorders. Main Outcomes and Measures: Primary outcome was common mental disorder measured at 6 months as a continuous variable via the SSQ-14 score, with a range of 0 (best) to 14 and a cutpoint of 9. The secondary outcome was depression symptoms measured as a binary variable via the 9-item Patient Health Questionnaire, with a range of 0 (best) to 27 and a cutpoint of 11. Outcomes were analyzed by modified intention-to-treat. Results: Among 573 randomized patients (286 in the intervention group and 287 in the control group), 495 (86.4%) were women, median age was 33 years (interquartile range, 27-41 years), 238 (41.7%) were human immunodeficiency virus positive, and 521 (90.9%) completed follow-up at 6 months. Intervention group participants had fewer symptoms than control group participants on the SSQ-14 (3.81; 95% CI, 3.28 to 4.34 vs 8.90; 95% CI, 8.33 to 9.47; adjusted mean difference, -4.86; 95% CI, -5.63 to -4.10; P < .001; adjusted risk ratio [ARR], 0.21; 95% CI, 0.15 to 0.29; P < .001). Intervention group participants also had lower risk of symptoms of depression (13.7% vs 49.9%; ARR, 0.28; 95% CI, 0.22 to 0.34; P < .001). Conclusions and Relevance: Among individuals screening positive for common mental disorders in Zimbabwe, LHW-administered, primary care-based problem-solving therapy with education and support compared with standard care plus education and support resulted in improved symptoms at 6 months. Scaled-up primary care integration of this intervention should be evaluated. Trial Registration: pactr.org Identifier: PACTR201410000876178.

Validation of screening tools for depression and anxiety disorders in a primary care population with high HIV prevalence in Zimbabwe.

BACKGROUND: In low income countries in Sub-Saharan Africa there are few validated tools to screen for common disabling mental disorders such as depression and general anxiety disorder (GAD). OBJECTIVES: We validated three screening tools: the Shona Symptom Questionnaire for common mental disorders (SSQ-14), the Patient Health Questionnaire for depression (PHQ-9), and the Generalized Anxiety Disorder questionnaire (GAD-7). The study participants were attendees at a primary health care clinic in Harare, Zimbabwe. METHODS: Consecutive adults aged 18 and above attending the clinic were enrolled over a two-week period in September 2013. Trained research assistants administered the screening tools to eligible participants after obtaining written consent. Participants were then interviewed by one of four psychiatrists using the Structured Clinical Interview of the DSM-IV (SCID). Performance characteristics were calculated for each tool, against the SCID as the gold standard. RESULTS: A total of 264 participants were enrolled, of whom 52 (20%) met the SCID criteria for depression alone, 97 (37%) for mixed depression and anxiety and 9 (3%) for anxiety alone. Of the 237 where HIV status was known, 165 (70%) were HIV positive. With the optimal cutoff of ≥9, the sensitivity and specificity for the SSQ-14 against a diagnosis of either depression and/or general anxiety were 84% (95%CI:78-89%) and 73% (95%CI:63-81%) respectively. Internal reliability was high (Cronbach α=0.74). The optimal cutoff for PHQ-9 was ≥11, which provided a sensitivity of 85% (95%CI:78-90%) and specificity of 69% (95%CI:59-77%) against a SCID diagnosis of depression (Cronbach α=0.86). The GAD-7 (optimal cutoff ≥10) had sensitivity and specificity of 89% (95%CI:81-94%) and 73% (95%CI:65-80%) respectively against a SCID diagnosis of GAD (Cronbach α=0.87). CONCLUSION: Screening tools for depression and GAD had good performance characteristics in a primary health care population in Zimbabwe with a high prevalence of HIV. These can be used for research and also in clinical care to screen patients who may benefit from treatment.
