Abstract

Background: There are limited available or published questionnaires that suit the Malay-speaking population to screen or assess child development, such as physical development, behaviour, emotions, cognition, communication skills, or socialisation. Standardised questionnaires completed by parents and teachers can provide different perspectives on the children with behaviour and developmental needs. It can be a supporting assessment for the professionals to support the diagnosis of the children. Thus, the current study focuses on other psychometric properties to validate the initial version of Malay-5-15R. Methods: The initial version of the Malay Version-Revised Five-To-Fifteen (5-15R) questionnaire has been content validated by the experts from the previous study. The validity of Malay-5-15R was further examined by conducting 1) pre-testing and face validity; 2) proofreading; and 3) pilot study. Results: The initial version of the Malay-5-15R questionnaire was found to be easily understood by participants during pre-testing. A pilot study was conducted on the two groups of population: parents with normally developing children and parents with children having a secondary diagnosis. Results showed that the initial version of the Malay-5-15R exhibited sufficient internal consistency (α > 0.93) and demonstrated an excellent coefficient of stability with a correlation coefficient value of 0.98. For convergent validity, most of the Malay-5-15R items have a significant correlation with items in the sub-domains, with r-values of greater than 0.30 (p < 0.05). Regarding divergent validity, about 99% of the items were correlated with r-values below 0.85 (p < 0.05). Conclusion: This study concluded that the Malay 5-15R questionnaire has good face validity, internal consistency reliability, test-retest reliability, convergent validity, and divergent validity, which are part of the psychometric properties. Therefore, it shows that the Malay 5-15R questionnaire is valid and reliable for use in the Malay-speaking population.
