Note: MDD = major depressive disorder; OCD = obsessive-compulsive disorder; any anxiety disorder = a lifetime diagnosis of at least one of the following: OCD, post-traumatic stress disorder, social phobia, specific phobia, panic disorder, agoraphobia, or generalized anxiety disorder; SCID = Structured Clinical Interview for DSM-IV. N’s represent lifetime “definite”/“probable” diagnoses and lifetime behaviors. Eating disorders include anorexia nervosa, bulimia nervosa, binge-eating disorder, purging disorder, and non-purging disorders characterized by a consistent pattern of excessive exercise, strict dieting, or fasting to control weight accompanied by overvaluation of weight or shape. Disordered eating behaviors include objective binge eating, subjective binge eating, loss of control over other eating episodes, or compensatory behaviors (such as vomiting or excessive exercise) to control weight.
