The purpose of this study was to investigate the diagnostic validity of MCMI-III (Millon, ) Scales in an Iranian population. The diagnostic validity of MCMI-III Scales was examined among psychiatric patients. Using operating characteristics (prevalence, sensitivity and specificity) of MCMI-III Scales, the predictive powers (positive, negative and overall) of the Scales was calculated. The results showed very good diagnostic validity for all MCM-III scales. Findings suggest MCMI-III Scales were found having high PPPs, NPPs and OPPs. The PPPs ranged from. to , and The NPPs ranged from to also OPPs ranged from to for all scales. Thus MCMI-III is a valid inventory and it can be used for Diagnosis personality disorders and clinical syndromes.
