Abstract

We report on the development of the Italian translation of the Schedule for Nonadaptive and Adaptive Personality-2 (SNAP-2). First, correspondence of the English and Italian versions was established through both the backtranslation method and administering both versions to a sample of 50 English-Italian bilingual participants. The translation’s psychometric properties were evaluated in 837 Italian community-dwelling adults (Sample 1) and 429 Italian psychiatric adults (Sample 2). The Italian SNAP-2 trait scales had adequate internal-consistency reliability and 6-month temporal stability in a sub-group (n = 97) of Sample 1 participants. The three-component factor structure of the 15 SNAP-2 trait scales replicated in both samples (median comparability coefficient = .96). The SNAP-2 trait scales in their Italian translation showed adequate nomological network validity with respect to Five Factor Model trait measures, self-reports and interview ratings of DSM-IV Axis II/DSM-5 Section II personality disorders and DSM-5 Section III dysfunctional personality domains.
