The present research design is survey of descriptive method. The statistical population consists of all adolescents aged 12 to 18 who have referred to counseling centers in Tehran. 300 adolescents were selected by nonrandom sampling method using incidental and convenient sample. The instrument used in this study is The Minnesota Multiphasic Personality Inventory-Adolescent-Restructured Form (MMPI-ARF) which has been standardized by Kamkary and Shokrzadeh. In order to determine the validity coefficient of the inventory, two methods of Cronbach's alpha and the split-half reliability have been used; Also in order to evaluate the concurrent validity, The Millon Adolescent Clinical Inventory-II (MACI-II) have been used. Findings showed that the validity coefficients with Cronbach's alpha and split-half in the scales of emotional dysfunction, demoralization, dysfunctional negative emotion, self-doubt, negative school attitudes, shyness, aggressiveness, psychoticism, and introversion were higher than 0/70, which indicates the desirable validity coefficients of these scales in adolescents referred to counseling centers in Tehran. Also, Findings showed that this instrument has concurrent validity with The Million Adolescent Clinical Inventory-II. Finally, it can be concluded that this Inventory has desirable psychometric properties.
