101580: A 4-Year Prospective Study of Eating Disorder NOS

About the Course:

Objective: To examine the course of Eating Disorder NOS (EDNOS) compared with anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED).
Method: Prospective study of 385 participants meeting DSM-IV criteria for AN, BN, BED and EDNOS at 3 sites. Recruitment was from the community and specialty clinics. Participants were followed at 6-month intervals over a 4-year period using the Eating Disorder Examination as the primary assessment.
Results: EDNOS remitted significantly more quickly that AN or BN but not BED. There were no differences between EDNOS and full ED syndromes, or the sub-types of EDNOS, in time to relapse following first remission. Only 18% of the EDNOS group had never had or did not develop another ED diagnosis during the study, however this group did not differ from the remaining EDNOS group.
Conclusion: EDNOS appears to be a way station between full ED syndromes and recovery, and to a lesser extent from recovery or EDNOS status to a full ED. Implications for DSM-V are examined.

Content for this course is based on an article from the International Journal of Eating Disorders, the official journal of the Association for Eating Disorders.
