Background and purpose: Stuttering disorders are among the disorders which their etiology is not entirely clear yet, and more psychological research is needed to clear our understanding of this disorder. Therefore, present study aimed to compare cognitive emotion relgulation, metacognition, and early maladaptive schemas in adolescents with stuttering and normal adolescents.Method: present study was a casual-comparative research. The study population consisted of all the secondary school students in Hamadan with stuttering who referred to speech therapist in the third quarter of 2013.21 patients suffering from stuttering and 21 normal individuals were selected using convenience sampling method. Data were collected using Young Schema Questionnaire (1998), cognitive emotion regulation (Garnfsky, Krayj & Aspynhavn, 2001), and meta-cognition Inventory (Wells, 2002). Data were analyzed using univariate analysis of variance.Results: The results showed that comparing to normal adolescents, adolescents with stuttering use more maladaptive strategies and less adaptive strategies. Furthermore, groups showed significant differences in terms of their metacognition and schemas (p<.001).Conclusion: According to our findings, in comparison to normal adolescents, adolescents with stuttering have higher levels of maladaptive emotion regulation strategies, metacognitive beliefs, and early maladaptive schemes.
