Design outcomes

Primary

MeasureTime frame
The primary endpoint of the study is the change in prosocial behavior from the start of the baseline phase to the end of the intervention phase. To objectively measure this change, daily assessments will be conducted, starting in the baseline phase and continuing throughout the intervention. Patients will self-register their prosocial activities each day, allowing for a continuous record of progress. Additional repeated assessments will take place at T0, T1, T2 and T3. 

Secondary

MeasureTime frame
Facilitators and barriers (i.e., intervention feasibility) will be described qualitatively.
