Abstract:  本研究ではASDのある子ども116名のWISC-IVのデータを収集し,従来のWISC-IVの4因子モデルとCHC理論に準拠した5因子モデルを想定した確認的因子分析を行い,その適合度及び下位検査構成を検証した。どのモデルも高い適合度を示したが,「結晶性能力」「視覚空間」「流動性推理」「短期記憶」「処理速度」で構成されるCHCモデルが最も当てはまりがよかった。下位検査構成では「行列推理」が「視覚空間」に負荷する結果となり,海外における因子分析の結果とは異なるものであったが,日本における先行研究と一致した。また,5つのCHCモデルによる合成得点を用いて,クラスター分析を行い5つのクラスターを抽出した。言語能力-視覚空間能力の優位性と処理速度の低さに特徴がある自閉性障害及びアスペルガー障害で従来から報告されてきたプロフィールが確認されたものの,「短期記憶」や「処理速度」に強みがあるクラスターも同定された。また,「視覚空間」と「流動性推理」の得点に乖離があるクラスターもあり,WISCモデルよりもCHCモデルでASDのある子どもの個人内差をより詳細に把握できることを示した。
 After children with autism spectrum disorder (N=116; mean age, 9.37 years, SD, 2.63) completed the Japanese version of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), the data were analyzed using confirmatory factor analyses to evaluate the goodness of fit and factor construction (factor loadings of subtests) based on the traditional WISC-IV 4-factor model, and the 5-factor model derived from the Cattell-Horn-Carroll theory: crystallized ability, fluid reasoning, visual spatial ability, short-term memory, and processing speed. The results indicated that although both models had high goodness of fit, the Cattell-Horn-Carroll model had better fit. With respect to factor construction, matrix reasoning loaded on visual spatial ability, rather than on fluid reasoning. This finding relating to factor construction is different from the results reported in studies done outside of Japan, but is consistent with the results of a previous study conducted on a standardized sample in Japan. Additionally, 5 clusters were extracted from the Cattell-Horn-Carroll model. The autism and Asperger profiles reported in previous studies were also identified in the present research. Furthermore, 2 clusters were identified, which were: (a) a cluster with relatively high scores on short-term memory, and (b) a cluster with relatively high scores on processing speed. Among those clusters, significant differences were found between the scores on visual spatial ability and the scores on fluid reasoning. These results suggest that this version of the Cattell-Horn-Carroll model may provide a more detailed understanding of individual differences among children with autism spectrum disorder than the WISC-IV model does.
