Psychometric properties of the adapted Malay Eating Disorder Examination-Questionnaire 6.0 (EDE-Q 6.0) among university students in Malaysia Nasehah Mohd Taib a , Jamilah Hanum Abdul Khaiyom b, * , Jusmawati Fauzaman b a Faculty of Business, Communication and Law, INTI International University, Persiaran Perdana BBN, Putra Nilai, 71800 Nilai, Negeri Sembilan, Malaysia b Department of Psychology, International Islamic University Malaysia, Jalan Gombak, 53100 Kuala Lumpur, Malaysia A R T I C L E INFO Keywords: Eating disorder Reliability Validity Malay University students ABSTRACT The “Eating Disorder Examination-Questionnaire” (EDE-Q) is a cost-effective eating disorder (ED) screening tool that has a signifcant relationship with the gold standard “Eating Disorder Examination” (EDE) interview. Though it has been widely used for clinical and research purposes, there is a dearth of effort to establish psy- chometric properties of the latest EDE-Q 6.0 in the Malaysian sample. The extant study adapted and validated EDE-Q 6.0 on Malaysian university's student population (N = 595) from a public university in the Klang Valley, Malaysia. Four factors of Restraint, Shape and Weight Concerns, Eating Concerns, and Shape/Weight Over- valuation were constituted from exploratory factor analysis. Still, they failed to indicate apparent replication of the original English EDE-Q 6.0. Malay EDE-Q 6.0 exhibited high internal consistency reliability (α = 0.93), acceptable test-retest reliability over 14 days, and acceptable equivalence reliability of its items with the original English version items. The Malay EDE-Q 6.0 global and subscales scores attained acceptable validity with the global scores of Malay EAT-26 (another ED scale) as evidence of convergent validity and with quality of life (QoL) scale for divergent validity. Accordingly, the adapted EDE-Q 6.0 Malay version is considered a valid and reliable instrument for assessing eating disorder psychopathology among Malaysian university students. 1. Introduction Before the 1990s, eating disorders (ED), specifcally anorexia nerv- osa cases, were reported in Malaysia (Buhrich, 1981) and anticipated to increase because of globalization and westernization (Pike & Dunne, 2015). Unfortunately, Malaysia lacks recent epidemiological data owing to the paucity of ED experts and psychometrically sound screening and diagnostic tools. The Eating Disorder Examination-Questionnaire (EDE- Q) (Fairburn & Beglin, 1994) is a self-reporting indicator of the Eating Disorder Examination interview, which is considered as a ‘gold stan- dard’ assessment. Moreover, EDE-Q is practical and inexpensive, exhibiting a signifcant correlation with the Eating Disorder Examina- tion interview, as reported in several comparative studies (Fairburn & Beglin, 1994). Though widely used for research and clinical purposes, scant research has addressed the latest EDE-Q 6.0 psychometric aspects (Fairburn & Beglin, 2008) in the Malaysian population sample. There- fore, this study aims to adapt EDE-Q 6.0 for Malaysian use. In general, the use of EDE-Q 6.0 in the United Kingdom (UK) (Barnes et al., 2012; White et al., 2014), the United States (US) (Darcy et al., 2013; Rand-Giovannetti et al., 2017; Rose et al., 2013), and Australia (AU) (Parker et al., 2015) successfully produced indicators of good reliability and validity. Several adapted EDE-Q 6.0 (Japanese, Italian, French, and Norwegian) also reported internal reliability that ranged between 0.70 and 0.96 (Mohd Taib & Abdul Khaiyom, 2019, 2020). The Italian EDE-Q 6.0 recorded good test-retest reliability indicators for its global (r = 0.80) and subscale scores (r = 0.66–0.83), at a mean interval of 10.1 days (Calugi et al., 2017). The Japanese EDE-Q 6.0 (Mitsui et al., 2017) with a restructured subscale recorded moderate validity with measures of a similar construct, which are Eating Attitude Test-26 (EAT- 26; Garner et al., 1982) and Eating Disorder Inventory-II (EDI-II; Garner, 1991). However, the structure of the underlying factor of EDE-Q 6.0 in these studies is highly controversial, when its limited ft is compared to the original four-factor model (Mohd Taib & Abdul Khaiyom, 2019). A factor analysis review of EDE-Q 6.0 by Rand-Giovannetti et al. (2017) highlighted that most research failed in replicating the original four- * Corresponding author at: Department of Psychology, International Islamic University Malaysia, Jalan Gombak, 53100 Kuala Lumpur, Malaysia.
