Method: The Persian versions of BIS, DII, EIQ and SSS, were completed by a group of normal individuals (39 subjects) and opiate abusers (30 subjects). Reliability was assessed using internal consistency.  Validity was checked using two methods: inter-scale correlation and known-groups comparison. Results: Cronbach's alpha coefficients in all questionnaires and in both groups ranged from 0.40 to 0.83. Except for “Boredom susceptibility” factor of SSS (0.22), the subgroups of questionnaires in BIS showed significant correlation (r=0.4).
