This randomized controlled trial evaluated the effectiveness of a 3-week multicomponent positive psychology self-help application on ability to adapt and mental well-being in the following the Covid-19 pandemic in adults with mild to moderate anxiety and depression levels. Outcomes were assessed online at baseline, posttest (three weeks after baseline), and follow-up (12 weeks after baseline). The intervention group (n = 118) received the application after baseline, whereas the control group (n = 116) received the app after completing posttest. Linear mixed models showed significant effects on ability to adapt, mental well-being, anxiety, depression, spiritual well-being, and self-compassion at post-test compared to the control condition (d = 0.56–0.96). Effects in the intervention group were maintained at follow-up. Results suggest that a multicomponent positive psychology self-help application can support adults with distress to recover after a psychologically disruptive pandemic.
