Lesbian, Gay, and Bisexual (LGB) individuals generally experience eating disorders at higher rates than heterosexual individuals. While there is limited research examining why LGB individuals experience higher levels of eating pathology, emotion regulation (ER) deficits have been associated with higher rates of other forms of psychopathology in this population. The present study examined the impact of specific ER deficits on the relationship between LGB status and eating pathology. We hypothesized that 1) LGB individuals would report higher levels of ER deficits, and 2) ER deficits would mediate the relationship between LGB status and eating pathology.
