Similarities and differences between women and men on eating disorder risk factors and symptom measures.

Researchers studying eating disorders in men often use eating disorder risk and symptom measures that have been validated only on women. Using a sample of 215 college women and 214 college men, we report on the validity of doing so with a set of measures chosen to reflect a wide range of risk factors and symptoms. The Bulimia Test-revised (BULIT-R), the restraint scale (RS), the three-factor eating questionnaire (TFEQ), the Eating Expectancy Inventory, and the eating attitudes test (EAT) all had the same factor structures for both genders, and tests of invariance showed that factor loadings, factor variances, and intercorrelations among factors were equivalent across gender. A modified Structured Clinical Interview for DSM-IV anorexic symptoms questionnaire did not perform adequately for either gender. Men produced slightly less reliable scores on virtually all measures, with the result that Pearson-based estimates of correlations among the measures were slightly lower for men. Men had lower scores on symptom and risk measures, but not on other eating measures.
