Task Shifting to Treat Depression and HIV Medication Nonadherence in Low Resource Settings

The TENDAI Study: Task Shifting to Treat Depression and HIV Medication Nonadherence in Low Resource Settings

A hybrid effectiveness-efficacy trial to evaluate a stepped care task shifted intervention to treat depression and HIV medication nonadherence in low resource settings in rural Zimbabwe.

Depression is commonly co-morbid with HIV infection in Zimbabwe and is consistently associated with worse adherence to antiretroviral therapy (ART). A task-shifted intervention for depression and ART adherence, suitable for delivery by non-specialists, could make a critical difference to the health and survival of people managing the challenges of HIV treatment in Zimbabwe. The TENDAI trial is a two-arm randomized controlled trial of an intervention for people on ART with viral non-suppression and clinically significant depression. It will be delivered at an HIV clinic in Marondera. TENDAI is a collaboration between the Department of Psychiatry, University of Zimbabwe College of Health Sciences, King's College London Institute of Psychiatry, Psychology and Neuroscience (London UK), and the Department of Psychiatry at Massachusetts General Hospital / Harvard Medical School.
