Session Abstract: The Level of Personality Functioning Scale (LPFS) has been a validated tool to assess personality dysfunction. The LPFS has used self-report measures to assess identity, self-direction, empathy, and intimacy. However, to date there have been few studies that have assessed personality dysfunction using a brief semi-structured clinical interview of the LPFS. The current study used a multi-step analysis to further investigate this. Using a sample of 88 undergraduate students, the study first validated if inter-rater reliability for the LPFS interview could be consistent across five raters. Next descriptive and reliability information for the items comprising the scales were analyzed. We then compared the interview rated LPFS to a self-report measure of the LPFS. Finally, Criterion A measures were measured against outcome variables. The results suggested that this semi-structured interview could be coded reliably (averaging five rater scores), had adequate internal consistency reliability for the total score (and three of four subscales), evidenced convergent validity with a self-report measure of the same construct, and was related to some (but not all) outcome measures, evidencing mixed criterion validity. Overall, results suggested that the clinical interview could be a valid tool in assessing personality dysfunction.
