Abstract
The present study compared the behavioral and psychological presentation of bulimia nervosa (BN), anorexia nervosa-binge/purge subtype (AN-B/P), and purging disorder (PD) patients. Data were collected from large multi-site centers in the US. Subjects (N = 2966) included current anorexia-binge/purge subtype (n = 138), current bulimia nervosa (n = 854), and current purging disorder (n = 41) patients. General demographic information from the PD group is provided, along with differences in behavioral symptomatology among the three groups. Results indicated that some PD subjects may have a history of objective binge eating episodes and have comparable or less severe psychopathology and behavioral symptoms of eating disorders when compared to AN-B/P and BN patients. Future research should consider investigating diagnostic crossover among the three groups to better determine if the disorders represent a continuing cycle of changing psychopathology or discrete diagnostic entities.
