Systematic Review on Eating Disorder Examination-Questionnaire 6.0 (EDE-Q 6.0): An Agenda for a Test Adaptation in Malaysia

The aim of this systematic review is to search and review literatures on the Eating Disorder Examination-Questionnaire 6.0 (EDE-Q 6.0), across cultures, in terms of their psychometric properties. Electronic search engines and databases, namely, Scopus, OvidMedline, Google Scholar, and reference tracking were used. The search terms used were eating disorder examination-questionnaire , EDE-Q , psychometrics , reliability , validity, and utility. Studies were included if they conducted psychometric evaluations on the EDE-Q 6.0 (i.e., English version) or adapted EDE-Q 6.0. The PRISMA guideline was also applied in selection of articles for review. Nineteen papers were retrieved on EDE-Q, specifically, the sixth version of the test has been translated and adapted to various languages and psychometrically evaluated on Japanese, Portuguese, American, Finnish, French, Norwegian, British, Australian, Italian, Iranian, and German populations. EDE-Q 6.0 has recorded good to excellent internal reliability across languages and cultures. Mixtures of findings were found in relation to its stability and validity. EDE-Q 6.0 on its factorial structure is very controversial with limited fitness into its initial theoretical four-factor structure. Nonetheless, EDE-Q 6.0 recorded a high utility values. However, the EDE-Q 6.0 is yet to be adapted into Malay, hence, calls for further research on its adaptation and its psychometric properties.
