Previous research has also shown that unified transdiagnostic treatment affects different variables. Therefore, according to the research background, there was a research gap in the effectiveness of unified transdiagnostic treatment in distress tolerance and emotion regulation of students with internalizing behavioral problems. Aims: The present study aimed to investigate the effectiveness of unified transdiagnostic treatment on distress tolerance and emotion regulation of students with internalizing behavioral problems. Methods: The present study was quasi-experimental with pre-test, post-test, and a control group. The statistical population of this study included first-grade high school female students with internalizing behavioral disorders in Tehran schools in 2019-2020. Thirty students with internalizing behavioral problems were selected by purposive non-random sampling and assigned into experimental (n = 15) and control (n = 15) groups. The experimental group received unified transdiagnostic treatment (Barlow et al., 2017) in ten 90-minute sessions over three months. The data were collected by the Youth Self- Report (Achenbach & Rescorla (2003), Distress Tolerance Scale (Simmons & Gaher, 2005), and Cognitive Emotion Regulation Questionnaire (Garnefsky, Kraaij & Spinhoven, 2001), and were analyzed by the multivariate analysis of covariance (MANCOVA). Results: The results showed that unified transdiagnostic treatment increased distress tolerance and improved students’ emotion regulation (p= 0.01). Also, the results of MANCOVA showed that the effect of unified transdiagnostic treatment on distress tolerance (F= 106.23), self-blame (F= 17.84), other-blame (F= 37.22), rumination (F= 36.12), catastrophizing (F= 38.67), acceptance (F= 18.86), refocusing on planning (F= 21.06), positive refocusing (F= 35.26), positive reappraisal (F= 29.69), and putting into perspective (F= 33.59) was significant (p= 0.01). Conclusion: According to the findings of this study, it can be stated that unified transdiagnostic treatment using emotional awareness training, learning to observe emotional experiences, re-identifying emotions, identifying patterns of emotion avoidance, and cognitive reappraisal increased distress tolerance and improved emotion regulation in students with internalizing behavioral problems.
