“…Eaves and Milner (1993), who did not have a nonautistic group, found the sensitivity (percentage of correct positives) of the ABC to be 88%. Five studies (Eaves et al, 2000;Sevin et al, 1991;Teal & Wiebe, 1986;Volkmar at al., 1988;Wadden et al, 1991) provided complete classification accuracy statistics. Across all studies, the mean sensitivity was 80%, the mean specificity (percentage of correct negatives) was 86%, and the overall percent of correct classification was 79%.…”

The reliability and construct validity of ratings for the Autism Behavior Checklist were examined with a sample of 198 children diagnosed with autistic disorder and conditions often confused with autism. Alpha coefficients for the five scales of the ABC as well as the Total Score were reported and the factor structure of the ABC was examined through confirmatory factor analysis. The results of the reliability analyses indicated that the Total Score alpha coefficient of the ABC was adequate for screening purposes, but the reliabilities of the scales were not. Confirmatory factor analyses indicated some support for alternate four-and five-factor models. © 2006 Wiley Periodicals, Inc. This investigation evaluated the reliability and construct validity of the Autism Behavior Checklist (ABC; Krug, Arick, & Almond, 1993), a widely used screening device for autistic disorder. The ABC was originally published in 1980 and it has not been revised since that date (Krug, Arick, & Almond, 1980). The 57 items of the ABC are grouped into five scales: Sensory, Relating, Body and Object Use, Language, and Social and Self-Help. The Total Score is the sum of all items in the five scales.Ordinarily, only the ABC Total Score, in raw score form, is used in the screening of autism; after inspecting the mean scores of five age groups (range ϭ 3 to 35 years of age), the authors determined that the use of separate standard scores for different age groups was unnecessary. A Total Score of 68, or one-half standard deviation below the autistic sample mean, is used as the "high-probability cut-off point for the classification of autism" (Krug et al., 1993, p. 27). On the other hand, the presence of a summary profile was intended to relate scale scores to diagnosis. For instance, when the Total Score falls in the range of 54 to 67, or when scale scores vary widely (e.g., scores of 0 for Sensory, Relating, and Social and Self-Help; scores of Ն37 for Relating; and scores ϭ 31 in Language), Krug et al. (1993) recommended that the rest of the ASIEP be administered to clarify further the ABC results.The use of the ABC scale scores in profile analysis implies that each scale contributes some degree of unique variance in the classification of autistic disorder. One of the more commonly used methods for evaluating the scale integrity of a measurement instrument is factor analysis. To date, three exploratory factor analyses of the ABC have been published (Miranda-Linné, 2001;Volkmar et al., 1988;Wadden, Bryson, & Rodger, 1991). Volkmar and his colleagues (1988) used the five-scale scores, chronological ages, and mental ages of 94 clinically diagnosed individuals with autism and 63 nonautistic individuals in a principal components analysis. Three factors resulted. The five ABC scales had salient loadings on first factor (range ϭ .56 to .80). Factor two contained two robust loadings: chronological age (Ϫ.80) and the ABC Language score (Ϫ.48). Only mental age loaded saliently on the third factor (.83). Based on this evidence, one may infer that the fi...

A b s t r a c t Objective: To examine the concurrent and criterion validity of the Autism Behavior Checklist (ABC). Methods: Three groups, comprising 38 mothers of children previously diagnosed with autism (DSM IV-TR, 2002), 43 mothers of children with language disorders other than autism, and 52 mothers of children who had no linguistic or behavioral complaints, were interviewed. In order to minimize the effect of maternal level of education, the questionnaire was completed by the researcher. To determine the concurrent validation, ANOVA and discriminant analysis were used. The ROC curve was used to establish the cutoff score of the sample and to examine the criterion validity. Results: The mean total score was significantly higher in the group of mothers of autistic children than in the other groups. The ABC correctly identified 81.6% of the autistic children. The ROC curve cutoff score was 49, and the sensitivity was 92.1%, higher than the 57.89% found when a cutoff score of 68 was used. The specificity was 92.6%, similar to the 94.73% obtained with a cutoff score of 68. Conclusions: The ABC shows promise as an instrument for identifying children with autistic disorders, both in clinical and educational contexts, especially when a cutoff score of 49 is used.

The Behavioral Summarized Evaluation (BSE), is a 20-item paper-and-pencil rating scale specifically designed for the measurement of behavioral parameters which could be related to biological data in autistic children involved in educational programs, neurophysiological studies, and therapeutic trials. The development of the scale, the validity, and reliability studies are presented in this paper. The results suggest that the BSE is an acceptable tool for the assessment of autistic behaviors, easy to handle, and accessible to both professionals and paraprofessionals of the medico-educative staff. It is a useful addition to the bioclinical researcher's evaluation battery for bioclinical and therapeutic studies. However, more work is suggested to further investigate the psychometric properties of this behavior assessment instrument.
