Speakers of Luganda, the most common indigenous language in Uganda, don’t have a word for “depression.” They use the terms yo’kwekyawa and okwekubazida, which roughly translate as “self-loathing” and “self-pity” and describe two distinct conditions; the former, which can include thoughts of suicide, is considered more severe. In Zimbabwe in the 1990s, researchers learned that the local Shona language had one word for everyday sadness (suwa) and another for a persistent, ruminative state that fit the clinical description of depression. This term, kufungisisa, which literally translates to “thinking too much,” unlocked communication between practitioners and patients.

In the early 2000s the Zimbabwean psychiatrist Dixon Chibanda recognized that his rural patients, many of whom were severely stressed by poverty and the multifold impacts of the HIV epidemic, were dying from a lack of mental health care. He recruited a corps of rural community members, predominantly grandmothers, and trained them to conduct informal therapy sessions with their neighbors on open-air “friendship benches.” In clinical trials, the grandmothers and their benches proved to be so successful in relieving the most incapacitating symptoms of depression that the approach has since spread to Kenya, Botswana, the Caribbean, New York City, and elsewhere.
