Abstract
Early reading skills assessment can detect children at risk of reading disorders. Kidarn is a child-friendly application designed to help clinicians and teachers conveniently and quickly assess young children’s reading skills in Thai. It consists of five subtests: letter-sound matching, phonological awareness, rapid automatized naming, blending, and segmenting. We evaluated Kidarn’s validity and reliability for use with grade 1 students. Content validity analysis by experts revealed the overall scale content validity (S-CVI) as good (S-CVI/UA = 0.92); scale validity at 0.88, 0.80, 0.73, 0.95 and 0.98 for Subtests 1 to 5, respectively, was also good. Test-retest reliability displayed each subtest’s intraclass correlation coefficient (ICC) to be between 0.6-0.85: within an acceptable range. Spearman’s correlation and total reading scores revealed r = 0.35, 0.59, -0.45, 0.61, and 0.60 for Subtests 1-5, respectively. In conclusion, Kidarn was found to be an acceptable validated instrument for early reading skill screening in Thai. With its minimal evaluator workload, it shows promise for use in the Thai education system.
