Abstract (English): |
The short-form of the Autism Spectrum Screening Questionnaire (ASSQ) was administered to 1,919 5-year-old children (1,002 boys/917 girls) and 4,374 school-aged children (ages 7-14, 2,221 boys/2,153 girls) from the same city to verify applicability of the ASSQ short-form in 5-year-old children. Fifty-nine of the 5-year-olds were diagnosed with autism spectrum disorder (ASD, 37 boys/22 girls). The results of confirmatory factor analysis confirmed factor structure to be the same for 5-year-olds as it was for school-aged children; however, multiple-group analysis demonstrated that estimates of factor loadings differed among groups. Furthermore, two-way (age (5-year-olds: school-age) ×gender (male: female)) analysis of variance found main effects of age and gender, but no significant effects of interaction. Meanwhile, multiple linear regression analysis with ASD diagnosis as the dependent variable and the three factors of the ASSQ short-form as independent variables demonstrated that each factor could significantly predict a diagnosis. Further, Receiver Operating Characteristic analysis by gender demonstrated favorable accuracy of identification (AUC=boys .92, girls .91), demonstrating the possibility that the ASSQ short-form can identify ASD in 5-year-old children with a certain degree of accuracy despite differences in scores and modes from school-age children. The findings suggested validity of cut-off scores of 3 for boys (sensitivity .94, specificity .81) and 4 for girls (sensitivity .73, specificity. 94) for screening purposes, and a cut-off score of 8 for both boys (sensitivity .49, specificity .99) and girls( sensitivity .54, specificity .98) for identifying cases strongly suspected of ASD. Positive precision value at the latter cutoff score was 61% for boys and 53% for girls, suggesting functionality of the cut-off score indicating a relatively strong suspicion of ASD.

5 歳児に対するASSQ 短縮版の妥当性について検証することを目的とし, 5 歳児群1919名(男 児1002名,うちASD の診断のあるもの59名(男児37名)と小学校2 年生から中学校2 年生4374名 (男児2221名)を対象にASSQ 短縮版を施行し,分析を行った。確認的因子分析の結果から, 5 歳 児での因子構造は,学齢期と同様であることが確認されたが,多母集団同時分析から,群間で因子 負荷量が異なることが示された。また,年齢群( 5 歳児:学齢期)×性別(男:女)の2 要因分散 分析では,年齢,性別に主効果が見られ,交互作用は有意ではなかった。一方,ASD の有無を従 属変数,ASSQ 短縮版の3 因子を独立変数とする重回帰分析からは,それぞれの因子が診断を有意 に予測することが示された。さらに男女別のROC 分析からは,良好な識別精度が示され(AUC= 男児.92,女児.91),学齢期での得点と様相が異なるものの,ASSQ 短縮版は5 歳児のASD を一 定の精度で識別できる可能性が示された。 5 歳児におけるスクリーニングを目的としたカットオフ 値は,男児で3 点(感度.94,特異度.81),女児で4 点(感度.73,特異度.94),ASD が強く疑 われるカットオフ値は,男女ともに8 点(男児=感度.49,特異度.99;女児=感度.54,特異度 .98)という設定が妥当であると考えられた。後者のカットオフ値での陽性的中率は,男児で61%, 女児で53%であり,ASD の比較的強い疑いを示すカットオフ値として機能すると考えられる。 [ABSTRACT FROM AUTHOR] |
