Measure	CST Intervention We will use a two-group stepped-wedge design. Group 1 will receive the intervention immediately. This will also allow group 2 to act as controls for group 1 and allow further analysis as a controlled trial, during secondary analysis. CST Intervention: The CST intervention comprises 14 sessions lasting 1-2 hours across 7 weeks. The CST manual has been adapted for use in this setting by members of our study team. Each session has a theme. Activities include tasks aimed at engaging participants in cognitive and physical tasks designed to improve quality of life. Sessions will be led and facilitated by a study nurse or occupational therapist. The sessions will be held at a local health centre of village hall.	Group 2 and group 2 will have their intervention delayed until after the end of the group 1 intervention. This will also allow group 2 to act as controls for group 1 and allow further analysis as a controlled trial, during secondary analysis.

In accordance with the CST manual protocol, patients will be allocated to groups to ensure a spread of abilities and ensure inclusivity. No group contains only one individual of a particular religion or gender, such that they may feel left out. We will allocate patients to groups to avoid excessive travel to the group meeting place, participants may be allocated to a group based on their geographical location.
