Email-Delivered Digital Positive Affect Intervention for Young Adults in Zimbabwe
Sponsor: Vilnius University
Summary
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.

Email-Delivered Positive Affect Intervention
This intervention is a brief email-delivered positive affect program designed specifically for young adults in a low-resource setting and it uses a structured three-step process of remembering, contemplating, and acting on positive experiences to intentionally increase positive affect. Unlike standard psychoeducational or symptom-focused mental health interventions, this program actively guides participants to identify personally meaningful sources of positive emotion and to translate them into daily behavioural activities. The intervention is fully automated and delivered entirely via email, making it highly scalable and accessible without the need for trained clinicians or face-to-face contact.
Psychoeducational Control
Participants receive email-based psychoeducational materials about stress, anxiety, depression, and coping strategies over three weeks. No structured behavioural exercises or positive activity tasks are included.
