| Research Abstract |
研究成果の概要(英文):Practice effect and stability of Japanese version of WISC-IIIwere investigated with students with Developmental Disabilities. In a test-retest interval group within 12 mounts (N=27), significant increases in all IQ score and index score were found ranged from 7.5 to 10.2 points from first to second testing. In ranged from 12 to 23 months (N=71), performance IQ(PIQ) and Full scale IQ(FIQ) were increased from 4.0 to 5.0 point significantly, but verbal IQ(VIQ) wasn't changed significantly. In ranged from 24 to 35 months (N=39), all IQ and index score weren't changed significantly. There were also significant correlations between increases of all IQ score, index score and test-retest interval. Factor structure of DN-CAS and correlations between WISC-III and DN-CAS index scores were investigated with Pervasive Developmental Disorders. The indications for assessment information in tests battery were found by those results.
