This study aimed to develop and validate whole grain KAP questionnaire among children. A
guided self-administered questionnaire was developed. In this cross sectional study, a total
of 207 children aged 9 to 11 years in Kuala Lumpur, Malaysia were recruited. Knowledge

was acceptable for knowledge (KR20=0.70), attitude (CA=0.72) and practice (CA=0.73).
Test-retest reliability intra-class correlation coefficients for knowledge, attitude and practice
domains were 0.80, 0.78 and 0.79 (p
