| Summary: | Having adequate knowledge, attitude, practice, and realistic perception (KAP2) of food
poisoning prevention will minimize the risk of food poisoning while dining out. However,
there is no validated KAP2 questionnaire on the prevention of food poisoning during
dining out, notably among consumers. Throughout the current research, a validated KAP2
questionnaire on food poisoning and prevention during dining was developed. A crosssectional pilot survey was conducted among 30 selected consumers in Kuala Nerus,
Terengganu. Convenience sampling was applied to the recruitment of consumers based on
inclusion and exclusion criteria. The KAP2 questionnaire comprised the knowledge
section (42 questions), attitude (15 questions), practice (13 questions) and the perception
(15 questions). Knowledge questions were analysed using difficulty and discrimination
index, while attitude, practice, and perception were analysed by construct validity and
reliability analysis. The difficulty index with less than 0.3 is considered as difficult,
between 0.30-0.70 as an acceptable value, and more than 0.70 as easy. The discrimination
index below than 0.2 is considered poor, between 0.2-0.24 as good, more than 0.35 as
excellent items. The construct validity was conducted by referring to the value of
Cronbach's alpha, inter-item correlation (˃ 0.30), item-total correlation (˃ 0.30), and
Cronbach's alpha if item deleted. The results were found from 42 knowledge items, 29
easy items, ten acceptable items and three difficult questions. The discrimination index
revealed that 25 items were poor, 11 items were excellent, three items had a good
discrimination index and three items needed to be revised. Based on construct validity,
five attitude’s items, three practice’s items and ten perception’s items were removed due
to inter-item correlation and item-total correlation value < 0.30. The reliability analysis of
the attitude portion was 0.848 which is a good reliability, 0.780 practice, and 0.611
perceptions to be found an acceptable value of reliability. Overall, the developed KAP2
questionnaire is a valid and reliable questionnaire that can serve as an evaluation tool for
measuring knowledge, attitudes, practice and perception in the prevention of food
poisoning during dining out among consumers. |
