Digital positive affect intervention (PAI)
"The Positive Affect Intervention (PAI) is a fully digital, self-guided program uniquely designed to deliver weekly 30-minute online sessions focused on cultivating positive emotions, meaning, and engagement, alongside daily ecological momentary prompts delivered thrice daily over six weeks. Distinctively, the intervention seamlessly integrates multimedia content (e.g., brief weekly videos introducing each session's core principles), practical exercises, and in-the-moment reflection, aiming to reinforce positive affect skills in real time. Its structure not only emphasizes proactive skill application through digital reminders but also systematically assesses user engagement and perceived helpfulness via ecological momentary assessments and post-session feedback questionnaires.~Unlike conventional digital interventions that primarily focus on symptom reduction through passive content consumption, this PAI leverages continuous ecological momentary engagement via a dedicated mobile app, e"
Self-monitoring intervention
The self-monitoring intervention serves as an active comparator designed to isolate the effects of mood self-awareness without introducing therapeutic content. Participants in this arm receive daily prompts via the Qualtrics mEMA mobile app, three times per day over a six-week period, instructing them to track their mood and emotional states through brief ecological momentary assessments (EMAs). Unlike the digital positive affect intervention, this arm does not include psychoeducational material, skills training, or active enhancement strategies; instead, it focuses solely on routine self-monitoring to control for digital engagement and expectancy effects. This minimalist structure allows for a clean contrast between passive self-observation and active therapeutic engagement, enabling robust evaluation of the added value of the Positive Affect Intervention beyond self-monitoring alone
