This study aimed to examine the effectiveness of a developmental mindfulness-based emotion regulation intervention on cognitive flexibility and identity coherence in adolescents. This study employed a randomized controlled trial with pretest, posttest, and five-month follow-up, including an experimental and a control group. The sample consisted of 30 adolescents from Tehran who were randomly assigned to the experimental group (n=15) or the control group (n=15). The experimental group received a developmental mindfulness-based emotion regulation intervention, while the control group received no intervention. Data were analyzed using repeated measures ANOVA and Bonferroni post-hoc tests in SPSS version 27. Results of repeated measures ANOVA revealed significant main effects of time and group, as well as significant time × group interaction effects for both cognitive flexibility and identity coherence (p<0.001). Bonferroni post-hoc comparisons indicated significant increases in both variables from pretest to posttest and follow-up in the experimental group, with no significant changes in the control group. The findings suggest that developmental mindfulness-based emotion regulation intervention is an effective and relatively stable approach for enhancing cognitive flexibility and identity coherence in adolescents and can be utilized as a developmentally informed mental health intervention.
