| Résumé : |
Purpose The Childhood Autism Rating Scale, Second Edition – Standard Version (CARS2-ST; Schopler et al., 2010) is commonly used for autism diagnostic decision making. Factor analytic investigations of the CARS2-ST, and the CARS, have produced various solutions, ranging from a single factor to five factors. We aimed to summarize factor analyses from published articles to develop and evaluate a consensus-based model. Methods We identified 13 published articles examining the factor structure of the CARS and CARS2-ST. The primary author grouped 38 factors from the 13 articles into three categories (Social Communication, 8 items; Restrictive/Repetitive Behavior/Sensory, 3 items; Emotion and Behavioral Dysregulation, 4 items) and subjected grouping decisions to inter-rater reliability analysis. The proposed model was tested via confirmatory factor analysis (CFA) with 302 children referred to a tertiary autism assessment clinic that included the CARS2-ST as part of the evaluation. The proposed model was evaluated against several other models using Δχ2 tests. Results Coding decisions were reliable across three raters (κ range.69–.80). The proposed model demonstrated good fit (e.g., Comparative Fit Index =.93; Root Mean-Square Error of Approximation =.06) and better fit the data than three other models, all Δχ2, p < .01. Conclusions A three-factor model consisting of Social Communication, Restrictive/Repetitive Behavior/Sensory, and Emotional and Behavioral Dysregulation domains fit CARS2-ST items well. The model fit CARS2-ST items better than four other models, including the two-factor model presented in the CARS2-ST manual. Implications for CARS2-ST interpretation and directions for future research are discussed. |
