The aim of this study is to validate the Italian version of the Lesbian, Gay, and Bisexual Positive Identity Measure (LGB-PIM), developed by Riggle and colleagues (2014). The LGB-PIM evaluate positive LGB identity in sexual minorities through five dimensions: "self-awareness", "authenticity", "community", "intimacy", and "social justice". The instrument was administered to 429 participants (129 lesbians; 179 gay males; 121 bisexuals), aged from 18 to 57 years (M = 27.20; DS = 7.26). Each dimension has high reliability, and factor analysis confirmed the five-factor structure, as found in the original study. The instrument demonstrated good psychometric properties although further validation studies are required.
