Standardization of Chinese Version Kyoto Developmental Test III:A study on the reliability and stability of the assessment in children aged 1-3 years

Abstract

To study the reliability and validity of Chinese Version Kyoto Development Test, we have analyzed the results of the test administered to 1096 Chinese children aged 1-3 years, including 558 boys and 538 girls, and the following conclusions were established. 1. Inter-observer Reliability: A random sample of 50 cases was selected . According to the results of the test of the two observers, it showed that the correlation coefficients between the two observers were 0.95-1.00, which reached significant level (p < 0.001). 2. Test-retest Reliability: The test-retest correlation coefficients of eight children with one week interval were 0.99-1.00, and the test-retest correlation coefficient between developmental quotients (DQ) ranged from 0.83-0.98. In addition, both of the results showed significant level (p <0.001). 3. Split-half Reliability: The correlation coefficient and the reliability coefficient between the scores based on odd-even method were similar to the statistical mark of Chinese Version Kyoto Development Test. 4. Criterion-related Validity: 267 children were tested on Chinese Version Kyoto Development Test and Chinese Developmental Screening Test with one week interval. Except posturalmotor domain, DQ for other domains and DQ for Chinese Version Kyoto Development Test and mental index of Chinese Developmental Screening Test all showed significant level (p < 0.001). Besides the above, Chinese Version Kyoto Development Test and Chinese Version S-M Social Living Ability Test were also carried on 302 subjects at the same time . The scores of each domain obtained from the two tests showed significant level (p < 0.05, p < 0.001). The results suggested that Chinese Version Kyoto Development Test seemed to be an available and effective developmental test.
