The purposes of this study were to compare DSM-IV diagnostic criteria and the Broad Categories for the Diagnosis of Eating Disorders (BCD-ED) scheme in terms of the number of cases of Eating Disorder Not Otherwise Specified (EDNOS) and to test which diagnostic tool better captures the variance of psychiatric symptoms in a Japanese sample. One thousand and twenty-nine women with an eating disorder (ED) participated in this study. Assessment methods included structured clinical interviews and administration of the Eating Attitudes Test and the Eating Disorder Inventory. The BCD-ED scheme dramatically decreased the proportion of DSM-IV EDNOS from 45.1% to 1.5%. However, the categorization of patients with the BCD-ED scheme was less able to capture the variance in psychopathology scales than the DSM-IV, suggesting that the BCD-ED scheme may differentiate ED groups less effectively than the DSM-IV. These results suggest that the BCD-ED scheme may have the potential to eliminate the use of DSM-IV EDNOS, but it may have problems capturing the variance of psychiatric symptoms.

Depression and coping in subthreshold eating disorders.

The eating disorder literature has sought to understand the role of comorbid psychiatric diagnoses and coping in relation to eating disorders. The present research extends these findings by studying the relationships among depression, coping, and the entire continuum of disordered eating behaviors, with an emphasis on subthreshold eating disorders.109 undergraduate females completed questionnaires to assess disordered eating symptoms, depressive symptoms, and the use of active and avoidant coping mechanisms. Hypotheses were tested using bivariate linear regression and multivariate linear regression.Results indicated that depression was a significant predictor of disordered eating symptoms after controlling for relationships between depression and coping. Although avoidant coping was positively associated with disordered eating, it was not a significant predictor after controlling for depression and coping.Previous research has found associations between depression and diagnosable eating disorders, and this research extends those findings to the entire continuum of disordered eating. Future research should continue to investigate the predictors and correlates of the disordered eating continuum using more diverse samples. Testing for mediation and moderation among these variables may also be a fruitful area of investigation. HubMed – eating disorders

Personality clusters and family relationships in women with disordered eating symptoms.

Personality clusters in women with eating disorders predict important clinical variables (e.g., social functioning) better than eating disorder diagnoses. However, it is unknown whether these findings generalize to samples with subclinical pathology. Further, little is known about associations between personality clusters and family relationships. This study sought to address these limitations by replicating personality clusters in a college sample of women with disordered eating symptoms Based on reported symptoms, women were divided into a restricting, binging and purging, or control (i.e., symptom free) group. Participants completed measures of personality, social functioning, and family relationships. Cluster analyses suggested three personality groups (i.e., Adaptive, Rigid, Dysregulated) which corresponded to those identified previously in clinical samples. Personality clusters, and not disordered eating groups, significantly predicted social functioning, and these clusters were differentially associated with family conflict type. Meaningful personality clusters are present in subclinical populations and have clinical utility in predicting social functioning and family relationships. HubMed – eating disorders
