|---|---|---|---|---|---|
| DSM-5 Eating Disorder Diagnoses: | |||||
| DSM-5 AN, BN, or BED (“probable”/“definite” dx only) | 8.3% (10/120) | 0.7% (3/402) | 21.906 (1, N = 522) | <.001 | 11.17 |
| DSM-5 AN, BN, BED, or OSFED (“probable”/“definite” dx only) | 12.6% (15/119) | 3.0% (12/402) | 17.293 (1, N = 521) | <.001 | 4.22 |
| DSM-5 AN, BN, BED, or OSFED (including “possible” dx) | 14.8% (18/122) | 3.0% (12/402) | 24.019 (1, N = 524) | <.001 | 4.94 |
| Disordered Eating Behaviors Reported on the SCID: | |||||
| Any Behavior | 39.2% (51/130) | 11.3% (45/400) | 51.789 (1, N = 530) | <.001 | 3.49 |
| OBE | 17.7% (23/130) | 2.0% (8/405) | 44.535 (1, N = 535) | <.001 | 8.96 |
| SBE | 9.4% (12/127) | 3.5% (14/405) | 7.468 (1, N = 532) | .006 | 2.73 |
| LOC | 7.4% (9/122) | 0.8% (3/399) | 18.225 (1, N = 521) | <.001 | 9.81 |
| Excessive Exercise, Fasting, or Strict Dieting | 26.2% (34/130) | 7.4% (30/404) | 32.702 (1, N = 534) | <.001 | 3.52 |
| Vomiting, Laxatives, or Other Medication | 3.8% (5/130) | 1.5% (6/405) | 2.733 (1, N = 535) | .098 | 2.60 |
Note: MDD = major depressive disorder; AN = anorexia nervosa; BN = bulimia nervosa; BED = binge-eating disorder; OSFED = other specified feeding or eating disorder; OBE = objective binge eating; SBE = subjective binge eating; LOC = loss of control over eating outside of OBEs/SBEs; SCID = Structured Clinical Interview for DSM-IV; dx = diagnosis. N’s represent lifetime diagnoses and behaviors. Anxiety disorders include DSM-IV obsessive-compulsive disorder, post-traumatic stress disorder, social phobia, specific phobia, panic disorder, agoraphobia, and generalized anxiety disorder. OSFED includes 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. N’s for some comparisons are smaller than the total N’s for MDD/anxiety disorder and no MDD/anxiety disorder groups because some participants had missing ED diagnoses/behaviors, and because participants with “possible” EDs were excluded from primary analyses of diagnoses.
