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. Copyright © 2010 John Wiley & Sons, Ltd and Eating Disorders Association.
