Invalidation and Mental Health among Nonbinary Individuals.

Abstract

This study examines the experience of a unique minority stressor, gender identity invalidation (henceforth referred to as invalidation), which is defined as the refusal to accept someone's gender identity as real or valid, among transgender and nonbinary (TNB) individuals. Data are drawn from a large and diverse sample of TNB adults who participated in a quantitative survey concerning transgender identity, minority stress, and mental health (N = 302). Invalidation was assessed using a novel 17-item scale that ascertains the extent to which respondents experienced invalidation across different social contexts. On average, TNB adults in this sample report low levels of invalidation, although a minority experience it at relatively high levels. Experiences of invalidation were significantly higher among nonbinary participants when compared with their binary trans peers. A series of multivariate regression models that control for sociodemographic factors (sex assigned at birth, race/ethnicity, education, age, and income) and well-established indicators of minority stress (felt stigma, enacted stigma) suggest that nonbinary gender identity is independently associated with poor mental health (assessed with the Global Severity Index), and that this association is mediated by invalidation. These findings suggest that invalidation, which is largely unexamined in existing research, merits greater attention as a particularly salient minority stressor influencing mental health among gender diverse populations, nonbinary populations in particular.
