“…Items are scored with a 7‐point Likert scale varying from 0 (“No days” or “Not at all”) to 6 (“Every day” or “Markedly”). The Portuguese version of the EDE‐Q28 (Machado et al, 2014) has shown acceptable to excellent internal consistency levels, with Cronbach's alphas ranging from .72 to .94 in nonclinical samples (Machado et al, 2014) and from .83 to .96 in clinical samples (Rodrigues, Vaz, Silva, Conceição, & Machado, 2019).…”

“…The last five items assess eating behaviors over the preceding week (i.e., binge‐eating episodes, self‐induced vomiting episodes, laxative misuse days, excessive exercise days, and eating restraint days). Participants in this study completed the Portuguese version of the ED‐15 (Rodrigues et al, 2019). This version of the ED‐15 has shown excellent internal consistency levels, with Cronbach's alphas ranging respectively from .93 to .91 in clinical and nonclinical samples.…”

Objective: The Eating Disorder Examination -Questionnaire (EDE-Q) is a widely used self-report measure of eating-disordered behaviors and attitudes. Recent studies utilizing confirmatory factor analyses (CFA) have proposed alternative and shorter forms. The aim of this study was to compare the full-length version of the EDE-Q and several proposed short forms (7-item, 8-item, and 18-item) in terms of their psychometric properties, including concurrent, convergent and discriminant validity, factor structure, and sensitivity to change. Methods: Participants from two eating-disorder clinical samples (N = 175 and 38) and from a nonclinical sample (N = 3,413) completed a battery of measures, including the Portuguese version of the EDE-Q. Analyses compared psychometric properties of the available short forms of the EDE-Q among each other.Results: All forms of the EDE-Q showed good internal consistency values, correlated highly among each other (r > .90) and with different measures of eating psychopathology (r > .80). All EDE-Q forms were able to distinguish between cases and controls with moderate-to-high accuracy and were sensitive to change. CFA failed to support the proposed factor structure for all the EDE-Q forms, except for the 7-item form.Discussion: The present study provides empirical background for choosing between different forms of the EDE-Q. Findings indicate that for nonclinical and for clinical research, including studies of treatment change and outcome, the short forms of the EDE-Q can be used. A shorter version is a viable alternative when less timeconsuming alternatives are needed, such to quickly screen for eating-disorder psychopathology or to perform session-by-session treatment monitoring.

“…In the field of ED assessment, Portuguese versions of well-established measures, such as the Body Shape Questionnaire [18,19], the Eating Disorder-15 questionnaire [20,21] and the Eating Disorders Examination Questionnaire [22,23], focus on body image evaluation. However, body-directed experiences, feelings and attitudes do not seem to be limited to body dissatisfaction, body weight and shape concerns in either ED or nonclinical samples.…”

The Portuguese version of the body investment scale: psychometric properties and relationships with disordered eating and emotion dysregulation

et al. 2020

Background: This study aimed to examine the psychometric properties of the Portuguese version of the Body Investment Scale (BIS) in a nonclinical sample of students and a clinical sample of outpatients with eating disorders, to analyse the differences in the BIS factors between the samples and to explore the relationships among body investment, eating disorder symptoms and difficulties in emotion regulation. Methods: The clinical (n = 93) and nonclinical (n = 448) samples completed self-report measures. Results: In contrast to the nonclinical sample, confirmatory factor analysis showed an acceptable fit for the original four-factor solution of the BIS in the clinical sample. This scale also demonstrated adequate internal consistency in both samples. Significant differences in BIS factors were found between the samples; outpatients with eating disorders presented more negative feelings about the body, less comfort with touch and lower levels of body protection than those of the students. In the clinical sample, significant relationships were found between these factors and a higher severity of disordered eating, as well as between these factors and higher difficulties in emotion regulation. Conclusions: The Portuguese version of the BIS is a psychometrically sound measure for the assessment of body investment, and it is especially appropriate in a clinical setting of outpatients with eating disorders.

Can early change in eating disorder psychopathology predict outcome in guided self-help for binge eating?

Purpose This study tests the value of a measure of eating disorder (ED) psychopathology in predicting outcome following guided self-help in a non-underweight sample with regular binge eating. It examines whether early reductions in ED psychopathology are associated with remission status at post-treatment. Methods Seventy-two adults with bulimia nervosa, binge-eating disorder, or an atypical form of these illnesses received up to ten sessions of cognitive behaviour therapy-based guided self-help. Using a session-by-session measure of eating pathology and associated reliable change indices, response was analysed using receiver operating characteristic analysis to predict outcomes at post-treatment. Results In this routine care setting, nearly one-quarter of the sample achieved remission following GSH, approximately two-thirds of whom showed early change in ED psychopathology. Early change prior to session 6 was accurate in predicting later remission. Individuals showing early change did not differ from others on baseline characteristics or rates of attrition. Conclusion Data suggest that a majority of those who respond to treatment will do so before the second half of treatment, information that could be used to ensure that evidence-based treatments are used as effectively as possible. Level of evidence Level III.
