Mindful eating practices could enhance one's mental well-being and increase one's enjoyment of food as well as their sense of satisfaction with their bodies. Hence, mindful eating was positively related to mental well-being, implying that those who were more mindful eaters also had higher levels of mental well-being. However, no previous research had directly applied "mindful eating" to the eating habits of sports science students and their relationship to mental well-being. Thus, the objective of this study was to determine the validity of the instrument in assessing the relationship between mindful eating and mental well-being among sports science students. There were 3 sections of the questionnaire that involved demographic information, Mindful Eating Questionnaire (MEQ) and Warwick-Edinburgh Mental Well-Being Scale (WEMWBS), which were validated by 5 experts. The content validity index (CVI) was determined to validate each question. The findings stated that all the questionnaires were interpreted as appropriate since the values of the I-CVI scores ranged between 0.8 to 1 and S-CVI/UA was 1. This study conveyed the good validity of the questionnaire, making it applicable in determining the relationship between mindful eating and mental well-being among sports science students in UiTM Sarawak.
