This study surveyed the ‎diagnostic criteria of DSM-IV-TR for the diagnosis of mobile phone ‎addiction in correspondence with Iranian society and culture.‎ Method: Two hundred fifty students of Tehran universities were entered into this ‎descriptive-analytical and cross-sectional study. Quota sampling method ‎was used. At first, semi- structured clinical interview (based on DSM-IV-‎TR) was performed for all the cases, and another specialist re-evaluated the ‎interviews. Data were analyzed using content validity, inter-scorer reliability (Kappa coefficient) and test-retest via SPSS18 software.
