Introduction: Food security can be defined as the availability of and accessibility to food, acquired in an acceptable means at any given time and place in a way that could maintain health and wellbeing. One critical dimension of food security is continued access to adequate food. To measure this dimension, the Food and Agriculture Organization (FAO) developed the latest measurement tool, namely the Food Insecurity Experience Scale (FIES), the first instrument to measure people who experience food insecurity globally. This study aimed to validate the construct validity and reliability of the Malay version of FIES (M-FIES) for Malaysians. Methods: This cross-sectional study was conducted among 145 households in Kuantan, Pahang. Rasch analysis was used to analyse the construct validity of FIES. Results: FIES met the Rasch model assumptions with all items having an infit value of between 0.7- 1.3 and an outfit value of <2.0. The item and person reliability were 0.97 and 0.71, respectively; while the item and person separation were 5.59 and 1.58, respectively. The FIES item severity indicated that the items “few food”, “healthy”, “skipped”, “ate less”, and “runout” were disordered. Conclusion: The M-FIES is a valid and reliable measurement tool for the food insecurity situation among households based on its construct validity assessed using the Rasch model. Furthermore, the severity of item in M-FIES was different in terms of order from the original FIES, suggesting that the same items may be interpreted differently due to cultural or societal differences.

Introduction: Food insecurity has a complex and multifaceted concept and definition, thus assessing it has been an ongoing challenge for researchers, health practitioners, and policy makers. Previous studies reported inconsistent findings on the prevalence and severity of food insecurity, depending on the measuring tools used. To overcome this limitation, this study aimed to translate and validate the Food Insecurity Experience Scale (FIES) for Malaysians, which has been used as a standard measurement by Food and Agriculture Organization (FAO). Methods: Two forward and backward translations involving experts in food insecurity studies and experts in language were done, as well as the pre-test and cognitive interview stipulated in World Health Organization (WHO) translation guidelines. Content and face validity were conducted as part of the validation process. Content Validity Index (CVI) was done to analyse content validity. Results: The harmonised Malay version of FIES was produced with 1.0 CVI, which was above the 0.8 criteria. Face validity showed good understandability and clarity of FIES. Conclusion: The translated Malay version of FIES had good acceptability, as well as good face validity when tested among the target audience. Thus, a full validation study of the Malay version FIES should be done before it is widely used to measure food insecurity in the population, specifically the Malaysian population.
