Abstract The diagnostic efficiency of the 11-item Iowa Personality Disorder Screen (IPDS; Langbehn et al., 1999) was evaluated in a nonclinical sample of young adults, 35\% of whom met DSM-III-R criteria for a personality disorder, in a retrospective analysis of SIDP-R data. Results indicated that two IPDS item sets (i.e., combinations of items) produced hit rates of more than 80\% along with good sensitivity, specificity, positive predictive power, and negative predictive power. Combined with the findings of Langbehn et al. (1999), these results suggest that the IPDS may be useful as a screening measure for personality disorder in both clinical and nonclinical populations.
