Confirmatory factor analytic structure and measurement invariance of quantitative autistic traits measured by the Social Responsiveness Scale-2 / Thomas W. FRAZIER in Autism, 18-1 (January 2014)  

Public ISBD [article]  inAutism > 18-1 (January 2014) . - p.31-44 Titre : Confirmatory factor analytic structure and measurement invariance of quantitative autistic traits measured by the Social Responsiveness Scale-2 Type de document : Texte imprimé et/ou numérique Auteurs : Thomas W. FRAZIER, Auteur ; Kristin R. RATLIFF, Auteur ; Chris GRUBER, Auteur ; Yi ZHANG, Auteur ; Paul A. LAW, Auteur ; John N. CONSTANTINO, Auteur Article en page(s) : p.31-44 Langues : Anglais (eng) Mots-clés : Asperger syndrome  autism  factor structure  pervasive developmental disorder Index. décimale : PER Périodiques Résumé : Understanding the factor structure of autistic symptomatology is critical to the discovery and interpretation of causal mechanisms in autism spectrum disorder. We applied confirmatory factor analysis and assessment of measurement invariance to a large (N = 9635) accumulated collection of reports on quantitative autistic traits using the Social Responsiveness Scale, representing a broad diversity of age, severity, and reporter type. A two-factor structure (corresponding to social communication impairment and restricted, repetitive behavior) as elaborated in the updated Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) criteria for autism spectrum disorder exhibited acceptable model fit in confirmatory factor analysis. Measurement invariance was appreciable across age, sex, and reporter (self vs other), but somewhat less apparent between clinical and nonclinical populations in this sample comprised of both familial and sporadic autism spectrum disorders. The statistical power afforded by this large sample allowed relative differentiation of three factors among items encompassing social communication impairment (emotion recognition, social avoidance, and interpersonal relatedness) and two factors among items encompassing restricted, repetitive behavior (insistence on sameness and repetitive mannerisms). Cross-trait correlations remained extremely high, that is, on the order of 0.66–0.92. These data clarify domains of statistically significant factoral separation that may relate to partially—but not completely—overlapping biological mechanisms, contributing to variation in human social competency. Given such robust intercorrelations among symptom domains, understanding their co-emergence remains a high priority in conceptualizing common neural mechanisms underlying autistic syndromes.

The Autism-Spectrum Quotient (AQ) Adolescent's Version in Turkey: Factor Structure, Reliability and Validity / Elif CETINOGLU in Journal of Autism and Developmental Disorders, 52-7 (July 2022)

Three assessment groups of adolescents, aged 11-18, were: 80 with Asperger syndrome/high-functioning autism (AS/HFA), 71 with other psychiatric disorders (PDs; 35 major depression, 18 obsessive-compulsive disorder, 18 social phobia), and 249 healthy controls. The scores of the AS/HFA group were significantly higher than the healthy control and PD groups. Cronbach ? value was 0.829. Ordinal alpha value was 0.90. We showed the AQ-adolescent four-factor structure in the factor analysis. In the test-retest of AQ-adolescent and subscale scores, "very strong" significant correlation values were detected. A cut-off score of 24 best distinguished the autism group from healthy controls with 0.975 sensitivity and 0.991 specificity.

The Strengths and Difficulties Questionnaire (SDQ) – Self-Report. An analysis of its structure in a multiethnic urban adolescent sample / Jörg RICHTER in Journal of Child Psychology and Psychiatry, 52-9 (September 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-9 (September 2011) . - p.1002-1011 Titre : The Strengths and Difficulties Questionnaire (SDQ) – Self-Report. An analysis of its structure in a multiethnic urban adolescent sample Type de document : Texte imprimé et/ou numérique Auteurs : Jörg RICHTER, Auteur ; Ase SAGATUN, Auteur ; Sonja HEYERDAHL, Auteur ; Brit OPPEDAL, Auteur ; Espen ROYSAMB, Auteur Année de publication : 2011 Article en page(s) : p.1002-1011 Langues : Anglais (eng) Mots-clés : Self-report SDQ  factor structure  CFA  adolescents  ethnic minorities Index. décimale : PER Périodiques Résumé : Background:  The SDQ is currently one of the internationally most frequently used screening instruments for child and adolescent mental health purposes. However, its structure, cross-cultural equivalence, and its applicability in ethnic minority groups is still a matter of discussion. Methods:  SDQ self-report data of 5,379 ethnic Norwegian and 865 ethnic minority adolescents with a variety of national origins was analysed by means of confirmatory factor analysis (CFA). Multi-group comparisons considering equal thresholds combined with more in-depth analyses on factor loadings, residuals, composite reliability, and average amount of variance explained by indicators of respective constructs were performed. Results:  CFA suggested a good fit of the five-factor model of the SDQ self-report in the subsample of ethnic Norwegian adolescents and an acceptable fit in ethnic minority subsamples without substantial differences between ethnic Norwegian SDQ data and data of Pakistani or those of ‘other ethnic minority’ adolescents. When assuming equal thresholds between response categories of the items as well as equal factor loadings the structure in the data significantly differed between ethnic Norwegian and both ethnic minority samples. Some factor loadings and some correlations between constructs significantly differed between ethnic Norwegian and both ethnic minority samples. The correlation coefficients between the hyperactivity factor and the conduct problems factor were too high in all three subsamples in order to establish distinct constructs. Composite reliability and average explained variance of the emotional symptoms factor were good in all samples, whereas they were low for some of the other factors. Conclusions:  To some extent the theoretically proposed five-factor structure of the Norwegian version of the SDQ self-report was supported in 15- to 16-year-old adolescents. However, the results of more detailed analyses raise questions about the interpretation of some subscales. When applying this screening method to Norwegian adolescents, our results suggest that the use of the total difficulty score of the SDQ in screening youth should be preferred over the subscale scores.

Temperament Similarities and Differences: A Comparison of Factor Structures from the Behavioral Style Questionnaire in Children with and Without Autism Spectrum Disorder / Brian D. BARGER in Journal of Autism and Developmental Disorders, 49-5 (May 2019)

The present study examined a widely used measure of temperament, the Behavioral Style Questionnaire (McDevitt and Carey in Behavioral Styles Questionnaire, Behavioral-Developmental Initiatives Scottsdale, AZ, 1975) to determine whether it contains the temperament traits theorized by its creators. Neither confirmatory nor exploratory factor analysis, using a sample of children with ASD and a population comparison group, identified the theorized nine temperament factors; many items did not strongly load on any of the original factors. A 10 factor solution best described the ASD data and a 9 factor solution best described the typical group's data. There were substantial similarities in the 9 factor solutions, but groups differed from one another enough to question construct similarity for several factors. These results highlight that more basic psychometric research is needed to better understand the BSQ in children with ASD.

A bifactor model with one general ASD factor and two specific factors (interaction-communication; restricted, repetitive behaviors) provided an adequate data fit. Internal consistencies of the SCL-ASD subscales and the total scale were >?.70. Correlations with measures of ASD traits were higher than correlations with measures of externalizing and internalizing symptoms. The results support a factor structure consistent with DSM-5/ICD-11 criteria. The SCL-ASD has sound psychometric properties.
