The present study aimed to investigate the effectiveness of choice theory-based group training on cognitive emotion regulation and parent-child relationships in male adolescents.<br> <strong>Materials and Methods:</strong> The research method was experimental with a pretest-posttest-follow-up design and a control group. The statistical population included all male students of the senior -high school in Dogonbadan city in the academic year 2019. Using the multi-stage cluster sampling method, 30 samples were selected and randomly assigned into experimental and control groups (n=15 per group). The research instrument included the Cognitive Emotion Regulation Questionnaire (CERQ) and The Parent-Child Relationship Survey. The reality therapy intervention was performed on the experimental group for ten 90-minute sessions. The follow-up was performed after 60 days. Multivariate analysis of covariance (MANCOVA) was then used to analyze the data.<br> <strong>Results:</strong> The participants included 30 male adolescents, aged between 15 and 17 years old. The research findings indicated that the choice theory-based group training was effective in promoting cognitive emotion regulation (F= 27.39, P= 0.0001) and parent-child relationship (F= 44.32, P= 0.0001). Also, their effects were sustainable until the follow-up period (P= 0.0001).<br> <strong>Conclusion:</strong> Choice theory-based group training, as a therapeutic and clinical intervention, can be used as an appropriate and effective technique to promote cognitive emotion regulation and parent-child relationships among adolescents.<br> <br> &nbsp;</div> Cognitive, Emotion, Parent-Child Relationship, Group Training, Choice Theory 12 21 http://jhs.mazums.ac.ir/browse.php?a_code=A-10-779-1&slc_lang=en&sid=1 Zahra Behmanesh ژهرا بهمنش zareanfah@gmail.com 10031947532846007565 10031947532846007565 No Department of Psychology, Yasooj Branch, Islamic Azad University, Yasooj, Iran. گروه روانشناسی، واحد یاسوج، دانشگاه آزاد اسلامی، یاسوج، ایران Shirali Kheramine شیرعلی خرامین shehnimn@gmail.com 10031947532846007566 10031947532846007566 Yes Social Determinants of Health Research Center, Yasuj University of Medical Sciences, Yasuj, Iran. دانشیار دانشگاه علوم پزشکی یاسوج Khosro Ramezani خسرو رمضانی kramezans@yahoo.com 10031947532846007567 10031947532846007567 No Department of Psychology, Yasooj Branch, Islamic Azad University, Yasooj, Iran. گروه روانشناسی، واحد یاسوج، دانشگاه آزاد اسلامی، یاسوج، ایران
