French adaptation of the eating disorder recovery self-efficacy questionnaire (EDRSQ): psychometric properties and conceptual overview.

High prevalence of Eating Disorders (EDs) and poor treatment outcome rates have urged research in the assessment of EDs. Self-efficacy is a key motivational factor in the recovery from EDs. A self-report measure, the Eating Disorder Recovery Self-Efficacy Questionnaire (EDRSQ), was recently developed to assess confidence in adopting healthy eating behaviours and in maintaining a realistic body image. The objectives of this study were to (a) translate the EDRSQ to French (EDRSQ-F), (b) assess the psychometric properties of this French version, and (c) establish normative data for a non-clinical sample. Participants were 203 undergraduate women. They completed the EDRSQ-F and measures of ED symptoms, depression and self-esteem. A confirmatory factor analysis (CFA) revealed a bi-factorial structure. Both scales demonstrated evidence of reliability and theoretically consistent evidence of construct validity. Findings support the validity of the EDRSQ-F and suggest it is a useful instrument for the assessment of EDs.
