Abstract Details

2015, PhD, University of Cincinnati, Arts and Sciences: Psychology.
Binge eating disorder (BED) shares many phenomenological and epidemiological similarities with OCD, and some evidence indicates that individuals with BED may experience obsessions and compulsions specific to their binge eating behaviors. Thus, the current studied aimed to determine the psychometric properties and clinical utility of the Y-BOCS-BE, a scale designed to assess binge eating related obsessions and compulsions. Participants included 211 treatment-seeking outpatients (89% female) who participated in 1 of 6 investigator initiated pharmacotherapy trials. Participants were diagnosed with current BED using the Structured Clinical Interview for DSM-IV-TR (SCID). The Y-BOCS-BE is a 10-item clinician administered scale used to assess obsessiveness of binge eating thoughts or urges and compulsiveness of binge eating behaviors. Factor analysis revealed three factors: (1) Distress, (2) Control, and (3) Interference. Internal consistencies were poor to moderate (α = .54 - .72). All subscales demonstrated adequate test-retest reliability (ICC = .69 - .89). The Distress and Interference subscales demonstrated convergent validity with other measures of BED severity (τ = .24 - .44) while the Control subscale did not. With regard to clinical utility, the Distress subscale approached significance predicting treatment response (p = .09), the Interference and Distress subscales demonstrated sensitivity to treatment effects (p < .05 and p = .07, respectively) and the Interference subscale demonstrated sensitivity to treatment-related change over time (p < .05). Initial examination of the psychometric properties and clinical utility of the Y-BOCS-BE indicates that the Interference and Distress subscales may offer promise; however, adaptations of the scale and additional replication of these findings are warranted. Overall, the current data are consistent with a scale in the beginning stages of development.
