The Yale-Brown-Cornell eating disorders scale self-report questionnaire: a new, efficient tool for clinicians and researchers.

OBJECTIVE: The YBC-EDS is a semistructured interview assessing core preoccupations and rituals related to eating disorders. METHOD: We developed and conducted an examination of the reliability and validity of a self-report questionnaire (SRQ) version of the YBC-EDS. Convergent validity of YBC-EDS-SRQ with the YBC-EDS was examined for 112 eating disordered patients. RESULTS: All subscales and total scores were significantly intercorrelated. Thirty-one additional patients completed YBC-EDS-SRQ at admission and again 1 week later. All correlations revealed significant test-retest reliability. Discriminant validity of the SRQ was evaluated for a smaller subset of participants who completed the Beck Depression Inventory (BDI) and State Trait Anxiety Inventory (STAI). There were no significant correlations between various symptom dimensions of the YBC-EDS-SRQ and the BDI and STAI. DISCUSSION: Taken together, these findings indicate that the self-report form of the YBC-EDS is both valid and reliable. The SRQ can serve as a useful and efficient assessment of eating disorder patients for clinicians and researchers.

An examination of early childhood perfectionism across anorexia nervosa subtypes.

OBJECTIVE: To examine childhood perfectionism in anorexia nervosa (AN) restricting (RAN), purging (PAN), and binge eating with or without purging (BAN) subtypes. METHOD: The EATATE, a retrospective assessment of childhood perfectionism, and the eating disorder inventory (EDI-2) were administered to 728 AN participants. RESULTS: EATATE responses revealed general childhood perfectionism, 22.3% of 333 with RAN, 29.2% of 220 with PAN, and 24.8% of 116 with BAN; school work perfectionism, 31.2% with RAN, 30.4% with PAN, and 24.8% with BAN; childhood order and symmetry, 18.7% with RAN, 21.7% with PAN, and 17.8% with BAN; and global childhood rigidity, 42.6% with RAN, 48.3% with PAN and 48.1% with BAN. Perfectionism preceded the onset of AN in all subtypes. Significant associations between EDI-2 drive for thinness and body dissatisfaction were present with four EATATE subscales. DISCUSSION: Global childhood rigidity was the predominate feature that preceded all AN subtypes. This may be a risk factor for AN.

The N170 to angry faces predicts anxiety in typically developing children over a two-year period.

Enhanced threat processing has been associated with elevated anxiety in adults, but less is known about how threat processing influences the developmental trajectory of anxiety in children. We used the N170 to measure threat (angry faces) processing in relation to child anxiety over a 2-year period. Participants were 27 typically developing 5-to-7-year-olds (13 females). Higher anxiety when children were aged 5 to 7 was associated with higher anxiety 2 years later, but only for children showing larger N170 amplitudes to angry versus happy faces. The N170 captures individual differences in threat processing that may characterize children at enhanced risk for anxiety.
