Sexual minority (SM) women may be at increased risk for certain eating disorder (ED) symptoms and report distinct body image concerns compared to heterosexual women. However, it is unclear how such symptoms differ across sexual orientations in treatment-seeking women, or if there are differences in treatment outcomes. This study examined group differences in (1) ED symptomatology at admission in a disaggregated sample of SM and heterosexual women presenting for ED treatment and (2) treatment outcomes.
