Psychological flexibility was measured using the Acceptance and Action Questionnaire-II (AAQ-II), Turkish version adapted by Yavuz et al. (2016), at four time points: pretest (Week 1, immediately before the first session’s therapeutic content), posttest (Week 6, immediately after the last session’s therapeutic content), 1-month follow-up, and 3-month follow-up.

1. Empathy was measured using the Child and Adolescent KA-SI Empathic Tendency Scale – Adolescent Form (Kaya & Siyez, 2010) at four time points: pretest (Week 1, immediately before the first session’s therapeutic content), posttest (Week 6, immediately after the last session’s therapeutic content), 1-month follow-up, and 3-month follow-up. 2.
