Objective: This study aims to investigate the psychometric properties of the Malay version of the Dutch Eating Behaviour Questionnaire (DEBQ) among Malaysian adults. Method: The Malay version of the DEBQ instrument was administered to 398 outpatients (269 women and 129 men) at the University of Malaya Medical Centre (UMMC). Confirmatory Factor Analysis (CFA) was conducted to study the construct validity of the instrument. Composite reliability coefficient, Raykov's rho, was used to determine the internal consistency. Results: The proposed three-factor structure for the DEBQ instrument was appropriate, although three items (Items 21, 14 and 27) showed problematic loadings with inappropriate model fit and were removed. The modified version had an appropriate model fit χ2/df = 2.129, TLI = 0.908, CFI = 0.918, RMSEA = 0.053 (90%CI = 0.048–0.058), close-fit P-value = 0.136 and satisfactory internal consistency of 0.914 for emotional eating scale, 0.819 for external eating scale and 0.856 for restrained eating scale. Discussion: The Malay version of the DEBQ is a valid instrument to study eating behaviour traits among Malaysian adults. Further research is warranted to determine if Items 14 and 27 are appropriate for the Malaysian population.
