After the suicide of one of his former patients, Zimbabwe-based psychiatrist Dixon Chibanda began training local grandmothers in evidence-based talk therapy. Since 2006 over four hundred grandmothers have been trained to deliver free services in more than seventy communities across the country while sitting on a “friendship bench” next to a local clinic. Friendship-bench patients were found after six months to have improved more significantly than patients receiving standard care. “I value human beings so much,” said one grandmother in the program. “I introduce myself and I say, ‘What is your problem? Tell me everything, and let me help you with my words.’ ”
