online media access in Thailand 4.0, measurement tool, health problems of school-age children


Development of an instrument for measuring health problem levels of school-aged children who have access to online media in the Thailand 4.0 (Instrument for measuring health problem levels of school-aged children: IMHP-SaC) requires high levels of reliability and validity, in order to achieve the maximum benefit of the measurement. This research aimed to create a tool to measure health problem levels of school-aged children who have access to online media in the Thailand 4.0 era.

Sample consisted of five experts for the instrumental verification, and 30 parents of school-age children who were purposively selected. Research tools were an expert opinion assessment form and a questionnaire for experimental groups in research. The study comprised three steps: defining objectives, creating questions, and checking quality of the measuring instruments. The data were analyzed for the Content validity index (CVI), the Index of-item-objective congruence (IOC), and the confidence value was the Cronbach-alpha coefficient.

The study results revealed that the created health problem scale of school-age children with access online media in the Thailand 4.0 has a CVI value of 0.93, an IOC value greater than or equal to 0.60, and
a Cronbach-alpha coefficient of 0.93. This developed measurement tool was reliable and suitable for further use to measure health problem levels of school-aged children who have access to online media
in the Thailand 4.0.
