Abstract

Objective: Evidence indicates that males account for a significant minority of patients with eating disorders (EDs). However, prior research has been limited by inclusion of small and predominantly non-clinical samples of males. This study aimed to (1) provide male clinical norms for widely used ED measures (Eating Disorder Examination Questionnaire [EDE-Q] and Eating Disorder Inventory-3 [EDI-3]) and (2) examine sex differences in overall ED psychopathology. Method: Participants were 386 male and 1,487 female patients with an ED diagnosis aged 16 years and older who completed the EDE-Q and EDI-3 upon admission to a residential or partial hospital ED treatment program. Results: Normative data were calculated for the EDE-Q (global and subscales) and the EDI-3 (drive for thinness, body dissatisfaction, and bulimia). Analyses of variance (ANOVAs) used to examine sex, ED diagnosis, and their interaction in relation to overall ED psychopathology revealed a consistent pattern of greater severity among females for ED psychopathology. Discussion: This study provides clinical norms on the EDE-Q and the EDI-3 for males with clinically diagnosed EDs. It is unclear whether the greater severity observed in females reflects qualitative differences in ED presentation or true quantitative differences in ED severity. Additional research examining the underlying nature of these differences and utilizing male-specific ED measures with clinical samples is warranted.
