Mindfulness-based interventions (MBIs) are being increasingly used toward improving mental health. Previous studies reached inconsistent conclusions regarding the effects of MBIs on the well-being and psychological distress of children and adolescents. Therefore, we conducted a meta-analysis summarizing the effects of MBIs on the well-being and psychological distress (i.e., anxiety, depression, and stress) of children and adolescents.
We searched electronic databases for reports on randomized controlled trials (RCTs) published until November 2020. Random effects models were used to calculate the overall effect size of each outcome variable for all participants. Subgroup and meta-regression analyses were conducted for categorical and continuous variables, respectively.
A total of 28 RCT studies (48 independent samples), comprising 7943 participants, were included in the final synthesis. The MBIs had a small effect on anxiety (g = 0.39), depression (g = 0.28), and stress (g = 0.30), and no significant effect on well-being. Subgroup analyses showed intervention time, mindfulness type, control type, and intervention population to be significant moderators. However, meta-regression analyses indicated that effect sizes were not moderated by intervention duration or study quality.
Our results confirmed MBI to be an alternative intervention for reducing psychological distress among both children and adolescents. The development and application of a shorter MBI, adapted for adolescents, could be addressed in future studies. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
