The Inter-Rater Reliability and Validity of the Italian Translation of the Structured Clinical Interview for Alternative Model for Personality Disorders Module I and Module II: A Preliminary Report on Consecutively Admitted Psychotherapy Outpatients.

To evaluate the reliability and convergent validity of the Structured Clinical Interview for Alternative Model for Personality Disorders (SCID-5-AMPD) Module I and Module II, 88 adult psychotherapy participants were administered the Italian translations of the SCID-5-AMPD Module I and Module II, Level of Personality Functioning Scale-Brief Form (LPFS-BF), Level of Personality Functioning Scale-Self Report (LPFS-SF), Personality Inventory for (PID-5), Personality Diagnostic Questionnaire-4+ (PDQ-4+), and Structured Clinical Interview for Personality Disorders (SCID-5-PD) relying on a Williams crossover design. SCID-5-AMPD Module I and Module II showed excellent inter-rater reliability. In terms of convergent validity, meaningful associations were observed between SCID-5-AMPD Module I scores and self-report measures of Criterion A; similarly, SCID-5-AMPD Module II trait scores were meaningfully related to PID-5 trait scores.
