Objective: We evaluated the psychometric properties and measurement equivalence of various forms of the Body Shape Questionnaire (BSQ) (Cooper et al., Int J Eat Disord, 6, 485-494, 1987) in American and Spanish women with and without an eating disorder diagnosis.
Method: Participants included four groups of women: Euro-American (n = 505), Hispanic-American (n = 151), and Spanish (n = 445) females without an eating disorder and Spanish women being treated for an eating disorder (n = 177).
Results: Single and multigroup confirmatory factor analyses using maximum likelihood estimation with robust standard errors tested the data for configural and metric invariance. Goodness-of-fit statistics indicated that the original and all alternate forms of the BSQ fit the data well across groups. Most factor loadings were similar across groups. We also developed a 10-item version that appeared to be invariant across groups.
Conclusion: Results strongly support configural invariance and offer some support for metric invariance.

Diagnostic accuracy of screening tests for eating disorders in adolescents and adults in primary health care: protocol for systematic review and meta-analysis.
BMJ Open

School of Nutrition, Federal University of Bahia, Salvador, Brazil.
Introduction: Eating disorders can be irreversible and, in many cases, fatal. However, the symptoms full recovery is possible, and early diagnosis is one, of many, important factors for the success of treatment. In this sense, the screening of risk behaviours arises as a relevant alternative to improve the prognosis of patients.

Background: Poor quality of life in adults with anorexia nervosa (AN) and persistent high rates of readmission highlight the necessity of developing interventions to optimize treatment outcomes. ECHOMANTRA is a novel online intervention based on interventions for carers (Experienced Carers Helping Others, ECHO) and patients (Maudsley Model of Anorexia Nervosa Treatment for Adults, MANTRA) with anorexia nervosa. The objective of this paper is to describe the study protocol of a randomized control trial (RCT) aimed at evaluating the efficacy of an adaptation of the ECHOMANTRA for adults AN inpatients and outpatients, and their carers, to be implemented as an add-on to treatment-as-usual (TAU).

Objective: The Eating Attitudes Test-26 (EAT-26) is considered the screening instrument of choice to identify eating disorders (ED) symptoms in clinical and community populations, showing a classical three-factor structure. This study assessed whether the factor structure of the EAT-26 in patients with ED was stable at admission and discharge from inpatient treatment.
Methods: We administered the EAT-26 to 207 female adolescents with ED at both admission and discharge.
