Friendship Bench: Zimbabwe grandmothers deliver therapy on park benches — now global

In 2005 Zimbabwe had roughly 10 psychiatrists serving 13 million people, and mental illness carried heavy stigma; even patients who reached Harare often could not afford the trip. After losing a young patient to suicide, psychiatrist Dixon Chibanda looked for care that could live inside communities.

Redesign mental-health care for a psychiatrist shortage: grandmothers trained in problem-solving therapy listen on public benches, lowering stigma.

From 2006 Chibanda and colleagues trained 14 volunteer grandmothers in Harare's Mbare township to deliver free problem-solving talk therapy, offered on wooden benches outside clinics with screening and referral for serious cases. The model was tested in a 2016 cluster randomized trial across 24 Harare clinics, comparing six sessions of lay-worker therapy plus peer support with standard care.

In the JAMA trial, intervention patients scored 3.8 versus 8.9 on the Shona Symptom Questionnaire at six months, and depression symptoms fell to 13.7% versus 49.9% in the control group. CBS News reported the model grew to more than 3,000 older listeners seeing over 300,000 people a year in Zimbabwe, with pilots in nine-plus countries including the United States.

In 2005 psychiatrist Dixon Chibanda lost a 25-year-old patient to suicide; her family had lacked the fare to travel the 200 miles to his hospital. Zimbabwe then had about 10 psychiatrists for 13 million people, so Chibanda began looking for a way to deliver care inside communities rather than waiting for patients to reach a specialist.

From 2006 he and colleagues trained 14 volunteer grandmothers in Harare's Mbare township in problem-solving therapy, delivered free from wooden benches outside clinics. The program was first named the Mental Health Bench; grandmothers suggested the friendlier name after stigma kept people away. Six-session therapy was paired with screening and referral, and a 2016 cluster randomized trial in 24 Harare clinics found intervention patients averaged 3.8 versus 8.9 on the Shona Symptom Questionnaire at six months, with depression symptoms at 13.7% versus 49.9% in the control group.

The model spread across all ten provinces of Zimbabwe and replicated in more than ten countries; by 2025 CBS News reported over 3,000 trained older listeners seeing more than 300,000 people a year in Zimbabwe, plus United States pilots run with HelpAge USA. Chibanda later published a book about the program, and his 2017 TEDWomen talk has drawn millions of views.

It reframed a resource problem as a design problem: instead of demanding more psychiatrists, it turned trusted grandmothers into the first port of call.

Putting therapy on a bench outside the clinic removed the stigma and transport costs that kept people from specialist care.

The grandmothers themselves were the insight: custodians of local culture, rooted in their communities, who could listen without judgement.

Rigorous testing — a cluster randomized trial published in JAMA — turned a local invention into evidence other countries could adopt.

When a profession is scarce, go to where trust already lives: respected community figures and ordinary public places can carry clinical ideas further than the clinic can.

Friendship Bench became one of global mental health's most cited task-shifting models, refined and adapted across all ten Zimbabwe provinces and replicated in more than ten countries, backed by over 100 peer-reviewed publications. CBS News documented expansion into nine-plus countries, including a Washington DC pilot with HelpAge USA. Chibanda published 'The Friendship Bench: How Fourteen Grandmothers Inspired a Mental Health Revolution' and remains professor of psychiatry at the University of Zimbabwe and LSHTM.
