The Delphi technique is a widely used and accepted method to obtain consensus among the experts. This technique uses a judgement to prove the accuracy of the content item when evaluating instrument. The objective of this study is to discuss the process of the three rounds Delphi technique to obtain consensus of concept mapping care plan and multiple choice questions (MCQ) in Diabetic Mellitus subject. In the first round, participants were given a structured questionnaire regarding item of concept mapping care plan and MCQ in Diabetic Mellitus subject. In the second round, the mean and median values of round one were added. In the third round, the mean and median values of round two were added. Participants were asked to rate the categorised responses from Round 1 on a scale of 1 to 5, with 1 being "Very Irrelevant" and 5 being "Very Relevant". This technique does not require that participants be collocated or meet face-to-face, thereby making it useful to conduct surveys with qualified people over a wide geographic area. The feedback process allows and encourages the selected Delphi participants to reassess their initial judgements about the information provided in previous iterations. The analysis of consensus data of the experts was done based on median, inter quartile range and quartile deviation on round one, two and three data. The median score was used to analyse the level of consensus of experts and result shows that in all three rounds Delphi the medium result more than 4. It reported that level of importance of the statements were high. As a conclusion, the concept mapping care plan and MCQ have meets the consensus by using three rounds of Delphi techniques. Therefore, the Delphi technique is the best method to obtain consensus in health care education research.

Foodborne diseases are one of the greatest public health threats, but they can be prevented by maintaining food safety practices. Although the food safety literature has been awash with studies from various food operations, there is very limited information on food safety in the food truck business. Therefore, this study aims to assess the level of knowledge, attitude, and practices related to food safety among food truck vendors. A cross-sectional study was conducted among 396 Malaysian food truck vendors using convenience sampling. Data was collected during the Recovery Movement Control Order due to the COVID-19 pandemic through a validated self-administered questionnaire and analyzed using SPSS version 25. The findings indicated that food truck vendors generally have fair knowledge (M = 78.8, SD = 9.09), a positive attitude (M = 94.8, SD = 5.95), and good practices (M = 84.7, SD = 6.62) regarding food safety during the COVID-19 pandemic. Hierarchical regression analysis further showed that food truck vendors’ level of education and knowledge of food safety are significant predictors of their food safety practices. This study provides an initial understanding of the food safety knowledge, attitude, and practices among food truck vendors and yields important information in promoting the food safety culture.

Self-efficacy plays an essential role in increasing health-promoting behaviour among older adults with chronic illness. Chronic illness requires high self-efficacy to manage the disease appropriately. Hence, the purpose of this study is to identify the relationship between self-efficacy and health-promoting behaviour among older adults with chronic illness. A cross-sectional study was conducted using a self-administered questionnaire to 218 older adults. The results from this study found a relationship between self-efficacy and health-promoting behaviour exists at rho 0.28 and p-value 0.001. This study revealed that self-efficacy strongly relates to health-promoting behaviour among older adults.eISSN: 2398-4287 © 2019. The Authors.
