Study summary

Mental illnesses often go undiagnosed or untreated in low-income settings. Mental health care may be especially important for the elderly - events in the lives of the elderly, like illnesses or deaths of peers, may put these individuals at high risk of mental illness. The study will constitute a randomized controlled trial aimed at reducing depression among elderly women. Through two interventions, the investigators will aim to improve women elder's outlook on life and relationships through cognitive behavioral therapy (CBT) and facilitated group activities. There will be a total of four treatment arms: one for CBT during home visits, one for facilitated group activities, one for both, and a control group receiving neither the CBT nor facilitated group activities. All activities will be delivered by lay government community volunteers. Randomization for group activities will be at the village level, and randomization for CBT will be at the individual-level within each village. Investigators will track outcomes of the elderly at two points in time: immediately after the main 12-week intervention period and 6 months after the main intervention period.

• Difficulty in performing daily activities/Functional impairment score — Assessed at 0 months after the intervention
  The 12-item WHO Disability Assessment Schedule 2.0 questionnaire is used. Participants will be asked the level of difficulty they have in doing each of the following tasks in the past 30 days due to health conditions: standing for long periods such as 30 minutes, walking a long distance (such as 1km), concentrating for 10 minutes, learning a new task like getting to a new place, washing whole body, getting dressed, taking care of household responsibilities, doing day-to-day work, dealing with people they do not know, maintaining a friendship, being emotionally affected by health problems, and joining in community activities. The scale is from 0-4, with 0 being no difficulty, 1 mild, 2 moderate, 3 severe, and 4 cannot do. The scores will be summed to create a cumulative score on a 0-48 scale.
