Diagnostic Criteria

DSM-V Diagnostic Criteria for Bulimia Nervosa

“

A. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following: 1. Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most individuals would eat in a similar period of time under similar circumstances. 2. A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating). AND B. Recurrent inappropriate compensatory behaviors in order to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise. AND C. The binge eating and inappropriate compensatory behaviors both occur, on average,at least once a week for 3 months. AND D. Self-evaluation is unduly influenced by body shape and weight. AND E. The disturbance does not occur exclusively during episodes of anorexia nervosa. Specify if: In partial remission: After full criteria for bulimia nervosa were previously met, some,but not all, of the criteria have been met for a sustained period of time. In full remission: After full criteria for bulimia nervosa were previously met, none of the criteria have been met for a sustained period of time. Specify current severity: The minimum level of severity is based on the frequency of inappropriate compensatory behaviors (see below). The level of severity may be increased to reflect other symptoms and the degree of functional disability. Mild: An average of 1-3 episodes of inappropriate compensatory behaviors per week. Moderate: An average of 4-7 episodes of inappropriate compensatory behaviors per week. Severe: An average of 8-13 episodes of inappropriate compensatory behaviors per week. Extreme: An average of 14 or more episodes of inappropriate compensatory behaviors per week.
