Introduction: The Asthma Knowledge Questionnaire developed by C. Rodriguez Martinez in 2005 was proved to be a valid instrument for asthma knowledge assessment for parents of children with asthma. 17 items were included in the questionnaire including their myths and beliefs, knowledge, and associated aspects. The objective of this study is to analyse the validity and reliability of the Malay version of the questionnaire. Methods: Forward-Backward translation method was used by language experts to obtain the Malay version of the questionnaire. The questionnaire was then given to twenty respondents at the Paediatric Institute Hospital Kuala Lumpur to ensure the clarity and relevance of the questionnaire as a pilot study. Subsequently, 60 respondents who fulfilled the inclusion and exclusion criteria were selected to proceed with the reliability test of the Malay version questionnaire. The results were analysed with SPSS version 26.0. The reliability and internal consistency were confirmed by intra-class correlation and Cronbach’s alpha coefficient. Results: There were 60 respondents to the questionnaire consisting of parents and caretaker who has child with asthma at the Institute of Paediatric Hospital Kuala Lumpur. The mean age of respondents was 34 ± 7.5year old. 91.7% of the respondents were female. The overall Cronbach’s alpha coefficient of the questionnaire was 0.84. Conclusion: The Malay version of the Asthma Knowledge Questionnaire has a good degree of validity, reliability and is culturally acceptable equivalent to the original version.
