The mediation role of emotion regulation strategies on the relationship between mindfulness effects, psychological well-being and distress among youths: findings from a randomized controlled trial

Abstract

AbstractThe Gaia program is a 12-week mindfulness intervention based on cultivating body, emotional, and ecological self-awareness, which has been shown to be effective in reducing children’s and adolescents’ internalizing problems, and improving psychological well-being, and psychological distress in early adolescents. To clarify the psychological processes underlying mindfulness effects on mental health among adolescents, the present study aimed to examine whether emotion regulation strategies (i.e., cognitive reappraisal and expressive suppression) may be considered as key processes linking the Gaia program effects to improvements in psychological distress and well-being. A total of 361 adolescents (mean age 14 years) were randomly assigned to one of two groups: the Gaia program (i.e., experimental group; N = 210) and waiting list (i.e., control group; N = 151). Measures were administered at three time points, approximately every three months: one week before treatment, one week after treatment, and three months after treatment. Using a structural equation model (SEM), we found that the Gaia Program had a positive and significant indirect effect on psychological well-being only via cognitive reappraisal as measured at follow-up [B = 0.181, 95% C.I. (0.012; 0.395)], whereas no significant indirect effects were found on psychological distress through cognitive reappraisal and expressive suppression. Findings from this study provide evidence of key emotional processes underlying the effects of a mindfulness intervention on positive but not negative psychological outcomes.
