Abstract:Background. This study aimed to investigate the impact of an intervention in the form of Ecological Momentary Interventions (EMI) based on principles of Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and Positive Psychology Interventions (PPIs) on reducing anxiety and depression while enhancing well-being. A secondary aim was to investigate whether EMI completion rates predict outcomes. Methods. The sample consisted of 31 participants aged 19-30 with elevated psychological distress scores (K10 ≥ 20). Over 23 days, participants underwent a 7-day baseline period followed by a 16-day intervention period where they received two EMIs daily. The interventions included gratitude journaling, savoring positive memories, an acceptance exercise, and a cognitive reappraisal exercise. Results. The intervention significantly reduced anxiety and depression but did not significantly improve well-being. The number of completed EMIs did not significantly predict changes in any of the outcomes. Exploratory analyses suggested greater improvements among participants with higher baseline symptom severity. Conclusion. EMIs combining CBT, ACT, and PPI strategies effectively reduce anxiety and depression symptoms but do not significantly enhance well-being. Future research should study optimizing EMI combinations and durations to maximize mental health benefits.
