Email-Delivered Digital Positive Affect Intervention for Young Adults in Zimbabwe

This study evaluates the feasibility, acceptability, and preliminary efficacy of a brief email-delivered positive affect intervention for young adults in Zimbabwe. The study uses a randomised controlled trial design with two parallel arms.

A total of 100 participants aged 18-25 years will be randomly assigned to two arms: an experimental arm receiving an email-delivered positive affect intervention or a control arm receiving psychoeducational materials. The intervention group will receive guided activities twice weekly over three weeks, focusing on identifying, reflecting on, and engaging in positive experiences. The control group will receive general psychoeducational materials on mental health without structured activities.

Assessments will be conducted at baseline and after the intervention. The primary outcome is feasibility( including recruitment, retention, and adherence) and acceptance. Secondary outcomes include changes in positive affect, symptoms of depression and anxiety,self-stigma, and suicidal ideation.
