--- - |2 Abstract Identity abuse (IA) comprises a set of abuse tactics that exploit discriminatory systems including homophobia, biphobia, and transphobia (Tesch & Berkerian, 2015). This study examined the factorial validity of the IA Scale (Woulfe & Goodman, 2018) with a large independent sample of lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals. Participants included 1,049 LGBTQ‐identified participants (Mage = 27.3, 71.9% White, 52.6% cisgender women, and 18.7% as other nonheterosexual identity in their sexual orientation), recruited through listservs. Participants completed an online survey measuring past‐year and adult exposure to identity, physical, and psychological abuse. Confirmatory factor analysis indicated that the measurement model had good fit to the data, and strong factor loadings were found across the seven items, confirming a unidimensional factor structure. Findings demonstrate the IA Scale's validity and reliability, supporting its use to assess the frequency of IA tactics experienced within intimate partnerships among LGBTQ individuals. - Journal of Community Psychology, EarlyView.
