Many organizations provide support services to children affected by AIDS in East and southern Africa. Yet few of these programmes have been evaluated. In Uganda, PLAN International, Makerere University, and the Horizons Program are collaborating on a study to assess the impact of an orphan support programme on the physical, educational, and emotional wellbeing of children. The researchers are also studying a different programme, called succession planning, in which children are reached before the death of the parent.
