Abstract


Disability sport is becoming more popular worldwide as shown by increased participation from athletes. The increase participation exerted pressure on the athletes to achieve better sports performance. One of the factors in enhancing sports performances is nutrition. A proper diet is needed for athletes, as it is an essential component in optimizing physical development and sports performance. Identifying the nutritional knowledge and supplement habits among disabled athletes will help maximize the benefits of nutrition. Despite the importance of nutrition, there is no validated questionnaire for identifying nutritional knowledge and supplement habits among disabled athletes in Malaysia. Thus, this study aims to develop and validate a questionnaire on nutritional knowledge and supplement habits among Malaysian disabled athletes and to examine the reliability of the questionnaire. This paper intends to discuss the validation of the developed questionnaire specifically on expert validation. The target population of this study is Malaysian disabled athletes. Firstly, the questionnaire is developed and adapted from previous literature on both nutritional knowledge and supplement habits for disabled athletes. Then, the developed questionnaire undergoes translation process before proceeding with validation and reliability process. Expert validation requires a panel of experts in sports nutrition, nutrition and dietitian fields. The questionnaire will be analyzed in terms of content validity ratio (CVR). The expected result of this study is a questionnaire validated by an expert panel on nutritional knowledge and supplement habits among Malaysian disabled athletes. In future research, the reliability of the questionnaire will be tested on 23 Malaysian disabled athletes, and their nutritional status will be identified. Hence, this study will help to promote the growth of disability sports in Malaysia and enhance the sports performance of disabled athletes in Malaysia through nutrition.
