Eating Disorder Examination Questionnaire (EDE-Q): Norms for young adult women
ABSTRACT In order to establish norms for the Eating Disorder Examination Questionnaire (EDE-Q) among young adult women, the questionnaire was administered to a large general population sample of women aged 18-42 yr in the Australian Capital Territory (ACT) region of Australia. Normative data were derived for EDE-Q subscales and for the occurrence of specific eating disorder behaviours, for each of five age bands (18-22, 23-27, 28-32, 33-37, 38-42 yr). Mean scores (SDs) for the Restraint, Eating Concern, Weight Concern and Shape Concern subscales for the total sample (n = 5,255) were, respectively, 1.30 (1.40), 0.76 (1.06), 1.79 (1.51) and 2.23 (1.65). The mean global score was 1.52 (1.25). The regular occurrence of objective and subjective overeating episodes was reported by 10.6% and 12.7% of participants, respectively. The regular use of self-induced vomiting, laxative misuse, and use of diuretics, was reported by 1.4%, 1.0%, and 0.3%, of participants, respectively, while 2.2% of participants reported regularly using diet pills. "Extreme dietary restraint" and "excessive exercise" were reported by 3.4% and 4.9% of participants, respectively. Both attitudinal and behavioural features of eating disorder psychopathology tended to decrease with increasing age. These data will inform researchers intending to use the EDE-Q in epidemiological studies.

ABSTRACT: The rigid and obsessional features of anorexia nervosa (AN) have led researchers to explore possible underlying neuropsychological difficulties. Numerous studies have demonstrated poorer set-shifting in patients with AN. However, due to a paucity of research on the connection between neuropsychological difficulties and the clinical features of AN, the link remains hypothetical. The main objective of this study was to explore the association between set-shifting and body checking. The sample consisted of 30 females diagnosed with AN and 45 healthy females. Set-shifting was assessed using the Wisconsin Card Sorting Test (WCST) and frequency of body checking was assessed using the Body Checking Questionnaire (BCQ). The analysis showed no significant correlations between any of the WCST scores and the BCQ. The results suggest that there is no association between set-shifting difficulties and frequency of body checking among patients with AN. An alternative explanation could be that the neuropsychological measure included in this study is not sensitive to the set-shifting difficulties observed in clinical settings. We recommend that future studies include more ecologically valid measures of set-shifting in addition to standard neuropsychological tests.Journal of Eating Disorders 04/2015; 3:17.

ABSTRACT: In this cross-sectional study, we investigated the influence of personal BMI on body size estimation in 42 women who have symptoms of anorexia (referred to henceforth as anorexia spectrum disorders, ANSD), and 100 healthy controls. Low BMI control participants over-estimate their size and high BMI controls under-estimate, a pattern which is predicted by a perceptual phenomenon called contraction bias. In addition, control participants' sensitivity to size change declines as their BMI increases as predicted by Weber's law. The responses of women with ANSD are very different. Low BMI participants who have ANSD are extremely accurate at estimating body size and are very sensitive to changes in body size in this BMI range. However, as BMI rises in the ANSD participant group, there is a rapid increase in over-estimation concurrent with a rapid decline in sensitivity to size change. We discuss the results in the context of signal detection theory. Copyright © 2015 Elsevier Ltd. All rights reserved.Body image 03/2015; 13:75-85.

ABSTRACT: The Five-Factor Model of personality is strongly linked to common mental disorders. Yet the relationship between the lower order personality traits (facets) of the model and eating disorder (ED) features remains unclear. The aim of the study was to explore how patients with non-anorexic ED differ from controls in personality and to examine the ability of personality facets to explain psychopathology. Female patients with non-anorexic ED (N = 208) were assessed on general psychopathology, ED symptoms and personality as measured by the NEO PI-R; and were compared on personality to age-matched female controls (N = 94). Compared to controls, patients were characterised by experiencing pervasive negative affectivity and vulnerability, with little in the way of positive emotions such as joy, warmth and love. Patients were also significantly less warm and sociable, and exhibited less trust, competence, and self-discipline. Finally, they were less open to feelings, ideas and new experiences, yet more open in their values. Among patients, personality facets explained up to 25% of the variance in ED and general psychopathology. ED patients have distinct patterns of personality. Identifying and focusing on personality traits may aid in understanding ED, help therapists enhance the treatment alliance, address underlying problems, and improve outcome.Journal of Eating Disorders 03/2015; 3(3).
