ABSTRACT

Introduction: Child injury is a leading cause of mortality and morbidity worldwide. Preschool teachers have the ability to prevent childhood injury and ensuring a safer environment. The aim of this study is to determine the reliability and validity of the Knowledge, Attitude and Practice on Child Safety Questionnaire for preschool teachers in Melaka.

Methods: A cross-sectional study was conducted from November 2013 to March 2014 on preschool teachers at 10 Jabatan Agama Islam Melaka (JAIM) preschools in Melaka. The development of the questionnaire took six months after extensive literature reviews as well as further discussion in an expert panel meeting. To verify the content validity of the questionnaire, a series of meetings and discussions was carried out with the members of panel made up of three experts from Universiti Sains Malaysia (USM), preschool teachers and representatives from Melaka Education Department. The face validity session was conducted among twelve preschool teachers in Kubang Kerian, Kelantan. Exploratory factor analysis was used to determine construct validity of the questionnaire. Cronbach’s alpha and ICC (test-retest) was used to determine internal consistency and reliability.

Results: Reliability and validity of the questionnaire was obtained through a pilot study involving 80 preschools teachers from selected (JAIM) preschools in Melaka. The 13 items in attitude domain were categorised into two subdomains: cognitive and behavioural with factor loading range 0.385-0.807. While the 12 items in practice domain were categorised into two subdomains: reaction and prevention with factor loading range 0.419-0.868. The internal consistency was acceptable for the domains of knowledge (0.828), attitude (0.934) and practice (0.908). All items were reproducible with test-retest scores ranged from 0.706-0.876.

Conclusion: The new Malay-language version of questionnaire on child safety is reliable and valid to assess the child injury knowledge, attitude and practice among preschool JAIM teachers in Melaka.
