Abstract
The current study investigated the distinctiveness of the eating disorders anorexia nervosa and bulimia nervosa. Apart from the diagnostic criteria for the disorders many other variables have been hypothesized to be consistently associated with these disorders. These variables include depression, personality disorders, personality traits, and family functioning. Self-report measures assessing these areas of functioning and psychopathology were administered to restricting anorexics, binge/purge anorexics, and bulimics. A discriminant function analysis was calculated and two significant functions resulted. The first function termed Self-Control/Body Image showed the greatest differentiation between restricting anorexics and bulimics. However, the clinical severity of the variables making up this function was not impressive. The second function termed General Psychopathology differentiated binge/purge anorexics from both restricting anorexics and bulimics. Examination of the functions provided little support for the continued separation of the eating disorder groups in the DSM diagnostic system. Suggestions for future research and refinements to the diagnostic definition of the eating disorders were provided.
