Efficacy and moderation of mobile application-based mindfulness-based training, self-compassion training, and cognitive-behavioral psychoeducation on mental health: A randomized controlled trial (Preprint)

Abstract

Mindfulness-based interventions, self-compassion training, and cognitive behavioral therapy have garnered much evidence in its salutary effects on mental health. With increasing application of smartphone and mobile technology on health promotion, the present study investigated the efficacy and possible moderators of mindfulness, self-compassion, and cognitive behavioral psychoeducation training mobile applications in the improvement of mental health.

Our aim was to examine the efficacy of three mobile application-based programs: mindfulness-based program (MBP), self-compassion program (SCP), and cognitive behavioral psychoeducation control (CBP) in improving well-being and reducing psychological distress. To further delineate the suitability of each program for which type of individuals, individual difference variables (i.e., nonattachment, self-criticism, discomfort with emotion, and tolerance for ambiguity) were explored for potential moderation.

The present study was a three-arm randomized controlled trial examining the efficacy of MBP, SCP with CBP. The course contents of the three programs were composed by a clinical psychologist and the mobile application was fully automated. Participants were recruited online and offline via mass mail, advertisements in newspapers and magazines, and social networking site. They were randomized into either one of the three conditions and completed pre-program survey assessment. Throughout the 4-week, 28-session program, participants spent 10 minutes daily in reviewing the course content and practicing various related exercises. Post-assessment and 3-month follow-up surveys were administered to measure changes over time. Indicators of mental health and psychological distress, as well as proposed moderators were self-assessed online at pre-program, post-program, and 3-month follow-up.

Among the 2,161 study participants, 508 and 349 completed the post- and 3-month follow-up assessment respectively. All three conditions (MBP, N = 703; CBP, N = 753; SCP, N = 705) were found to be efficacious in improving mental well-being and reducing psychological distress. No significant differences regarding usage and users’ satisfaction were found among the three conditions. None of the proposed moderators were found to be significant.

Mindfulness-based, self-compassion, and cognitive behavioral psychoeducation mobile applications were efficacious in improving mental health and reducing psychological distress among young adults at post-program, and such improvements were maintained at 3-month follow-up. Future app-based psychological training programs should consider gamification and personalization of content or feedback to enhance engagement and mitigate the high attrition rate that are common in app-based health promotion programs.
