The present study examines the validity of severity diagnostic criteria for bulimia nervosa. The sample included 87 subjects. The participants were classified into 1 of 3 groups according to the Mental Disorders-IV criteria: bulimia nervosa (n = 20), sub-threshold bulimia (n = 37), and non-eating disorder (n = 30). The groups were compared regarding perceived pressure to be thin, concerns about bodshape, dietary restraint, several measures of eating and weight-related habits and attitudes, depressive symptoms, anxiety, self-esteem, social difficulties, obsessiveness, and impulsivity. Bulimics and sub-clinical bulimics differed from controls in most constructs. Few differences were found between sub-threshold and full-syndrome, raising questions about the diagnostic validity of the frequency threshold. Further evaluation of the severity criterion specified for bulimia nervosa is needed.

Abstract
The present study examines the validity of severity diagnostic criteria for bulimia nervosa. The sample included 87 subjects. The participants were classified into 1 of 3 groups according to the Mental Disorders-IV criteria: bulimia nervosa (n = 20), sub-threshold bulimia (n = 37), and non-eating disorder (n = 30). The groups were compared regarding perceived pressure to be thin, concerns about bodshape, dietary restraint, several measures of eating and weight-related habits and attitudes, depressive symptoms, anxiety, self-esteem, social difficulties, obsessiveness, and impulsivity. Bulimics and sub-clinical bulimics differed from controls in most constructs. Few differences were found between sub-threshold and full-syndrome, raising questions about the diagnostic validity of the frequency threshold. Further evaluation of the severity criterion specified for bulimia nervosa is needed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
