The Iowa Personality Disorder Screen (IPDS)

The Iowa Personality Disorder Screen (IPDS) is a brief 11-item screen originally administered alongside a brief interview [500], but has since been adapted into a self-report measure [502]. The screening tool asks people to indicate whether or not they identify with common traits found among people with personality disorders, including both general personality disorder criteria as well as specific criteria. Research suggests that identifying with five or more of these traits is indicative of a probable personality disorder among people attending AOD treatment [503]. The IPDS has demonstrated good diagnostic accuracy, sensitivity, specificity, concurrent validity, and internal consistency among people attending AOD treatment [503, 504], as well as good psychometric properties among people attending mental health treatment [505]. A comparison of screening tools for personality disorders found that the IPDS is one of the most reliable and valid screening instruments for personality disorders [506].
