The children with ASD were diagnosed with Autism (n1 = 27) or High-Functioning ASD (n2 = 26). The three subscales of the SCQ were confirmed and the modification indices produced an acceptable fit. The Cronbach-a coefficient was high and acceptable for all subscales and the total SCQ score. Roc analysis yielded an optimal cut-off point of 15 for the Autism group versus the Non-ASD group with a sensitivity of 96.3% and a specificity of 98.7%. For both the ASD group as a total and the High-Functioning ASD group the optimal cut-off point was found to be 11 with a satisfactory balance between sensitivity and specificity. The Greek version of SCQ seems to be a valid and reliable instrument for 7 to 10 year-old children. The findings support the need for adjusting the cut-off point to the subject's level of functioning.

New Interview and Observation Measures of the Broader Autism Phenotype: Description of Strategy and Reliability Findings for the Interview Measures / Jeremy R. PARR in Autism Research, 8-5 (October 2015)  

Public ISBD [article]  inAutism Research > 8-5 (October 2015) . - p.522-533 Titre : New Interview and Observation Measures of the Broader Autism Phenotype: Description of Strategy and Reliability Findings for the Interview Measures Type de document : Texte imprimé et/ou numérique Auteurs : Jeremy R.

BAILEY, Auteur Article en page(s) : p.522-533 Langues : Anglais (eng) Mots-clés : broader autism phenotype  informant interview  self-report interview  interrater reliability  retest reliability Index. décimale : PER Périodiques Résumé : Clinical genetic studies confirm the broader autism phenotype (BAP) in some relatives of individuals with autism, but there are few standardized assessment measures. We developed three BAP measures (informant interview, self-report interview, and impression of interviewee observational scale) and describe the development strategy and findings from the interviews. International Molecular Genetic Study of Autism Consortium data were collected from families containing at least two individuals with autism. Comparison of the informant and self-report interviews was restricted to samples in which the interviews were undertaken by different researchers from that site (251 UK informants, 119 from the Netherlands). Researchers produced vignettes that were rated blind by others. Retest reliability was assessed in 45 participants. Agreement between live scoring and vignette ratings was very high. Retest stability for the interviews was high. Factor analysis indicated a first factor comprising social-communication items and rigidity (but not other repetitive domain items), and a second factor comprised mainly of reading and spelling impairments. Whole scale Cronbach's alphas were high for both interviews. The correlation between interviews for factor 1 was moderate (adult items 0.50; childhood items 0.43); Kappa values for between-interview agreement on individual items were mainly low. The correlations between individual items and total score were moderate. The inclusion of several factor 2 items lowered the overall Cronbach's alpha for the total set. Both interview measures showed good reliability and substantial stability over time, but the findings were better for factor 1 than factor 2. We recommend factor 1 scores be used for characterising the BAP. Autism Res 2015, 8: 522–533. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

The sample studied included families containing at least two individuals with autism spectrum disorder; observations were undertaken by the researcher who interviewed the subject. An exploratory factor analysis suggested a single factor was most appropriate (Cronbach’s ? of 0.78). There was a modest but significant retest correlation of 0.42. Correlations between live ratings and blind consensus ratings of vignettes were high (0.93). Correlations with the interview measures were moderate but statistically significant. In conclusion, the observational scale provides a promising start but further work is required before general use can be recommended.

Using the Autism Diagnostic Interview-Revised and the Autism Diagnostic Observation Schedule-Generic for the Diagnosis of Autism Spectrum Disorders in a Greek Sample with a Wide Range of Intellectual Abilities / Katerina PAPANIKOLAOU in Journal of Autism and Developmental Disorders, 39-3 (March 2009)

The agreement of the ADOS-G and the ADI-R with the clinical diagnosis was estimated as satisfactory and moderate, respectively, while both instruments presented with excellent sensitivity for the diagnosis of autistic disorder along with satisfactory specificity. ADOS-G/ADI-R agreement was estimated as fair. Our results confirm the discriminant validity of ADI-R and ADOS-G in diagnosing pervasive developmental disorders in children and adolescents with a wide range of intellectual abilities.
