The study&nbsp;population consisted of visually impaired male students of the primary and secondary high&nbsp;school at the Omid-e-Mashhad Educational Center for the Blind in the 2014-2015 academic&nbsp;year. Beck&rsquo;s Self-Concept Scale was used as a research tool, and 20 students with scores one&nbsp;deviation standard below the mean were randomly selected and divided into experimental and&nbsp;control groups. The experimental group received nine weekly sessions of cognitive-behavioral&nbsp;therapies, each of 90 minutes. The post-test data analysis was performed by conducting SPSS&nbsp;using descriptive statistics methods (mean and standard deviation for the study variables&nbsp;and tables) and inferential statistics methods (including Kolmogorov-Smirnov test, t-test for&nbsp;independent groups, Lewin test, and co-variance test).<br> <strong>Results:</strong> The results of covariance analysis revealed that the intervention of cognitive&nbsp;behavioral group counseling can significantly increase the self-concept among the participants&nbsp;of the experimental group.<br> <strong>Discussion:</strong> Cognitive-behavioral group counseling sessions can improve the self-concept&nbsp;of visually impaired adolescents. Moreover, positive self-concept will increase their social&nbsp;interaction and mental health.</p> Self-concept, Visually impaired, Cognitive-behavior counseling 51 58 http://irj.uswr.ac.ir/browse.php?a_code=A-10-201-9&slc_lang=en&sid=1 Mahmood Yaghotian No Department of Counseling, Faculty of Human Sciences, University of Bojnord, Bojnord, Iran.
