Exploratory Factor Analysis of SRS-2 Teacher Ratings for Youth with ASD / Andrew T. NELSON in Journal of Autism and Developmental Disorders, 46-9 (September 2016)

Results of the exploratory factor analysis yielded a four-factor correlated solution. The individual factors and total score demonstrated satisfactory internal consistency reliability for screening purposes. When applying the lowest pre-established cut score (T ? 60; minimum indication of clinically significant symptoms/impairments), 85 % of the sample had ratings in that range or higher (more severe). Implications for assessment and future research are provided.

Exploratory factor analysis of the Adapted Skillstreaming Checklist for children with autism spectrum disorder / Christopher LOPATA in Autism, 24-2 (February 2020)

Prior studies provided support for the reliability and criterion-related validity of the Adapted Skillstreaming Checklist total score for these children; however, no studies have examined the Adapted Skillstreaming Checklist factor structure. This exploratory factor analysis examined the factor structure and internal consistency of parent ratings on the Adapted Skillstreaming Checklist for a sample of 331 children, ages 6-12 years, with autism spectrum disorder without intellectual disability. Results yielded a correlated three-factor solution. The individual factors and total score demonstrated very good internal consistency reliability. Findings supported the presence and interpretability of three subscales, as well as derivation of a total composite reflecting overall prosocial and adaptive skills and behaviors. Implications for assessment and research are discussed.

A Distinct Three-Factor Structure of Restricted and Repetitive Behaviors in an Epidemiologically Sound Sample of Preschool-Age Children with Autism Spectrum Disorder / L. HIRUMA in Journal of Autism and Developmental Disorders, 51-10 (October 2021)

This study examined RRBs among 827 preschool-age children, ages 35 to 71 months, through an exploratory factor analysis of RRB items from the Autism Diagnostic Interview-Revised (ADI-R) collected through the Study to Explore Early Development. The factor structures of RRBs among children with confirmed ASD versus those with non-autism developmental concerns were qualitatively compared. Correlations between RRB factors and participant characteristics were examined in the ASD group. Three conceptually well-defined factors characterized as repetitive sensorimotor behaviors (RSMB), insistence on sameness (IS), and a novel stereotyped speech (SPEECH) factor emerged for the ASD group only. Distinct factors were supported by different clinical correlates. Findings have implications for improving differential diagnosis and understanding of ASD symptomatology in this age range.

Anxiety scale for children with autism spectrum disorders: Translation, cross-cultural adaptation and psychometric evaluation / Maryam KHAN ; Dr Sabahat HAQQANI ; Muqqadas SABA in Research in Autism, 123 (May 2025)  

Public ISBD [article]  inResearch in Autism > 123 (May 2025) . - 202548 Titre : Anxiety scale for children with autism spectrum disorders: Translation, cross-cultural adaptation and psychometric evaluation Type de document : Texte imprimé et/ou numérique Auteurs : Maryam KHAN, Auteur ; Dr Sabahat HAQQANI, Auteur ; Muqqadas SABA, Auteur Article en page(s) : 202548 Langues : Anglais (eng) Mots-clés : Anxiety  Autism  Assessment  Anxiety Scale for children with Autism Spectrum Disorders  Exploratory Factor Analysis Index. décimale : PER Périodiques Résumé : Background Anxiety is one of the most common co-occurring disorders in children with autism spectrum disorder (ASD) that adversely affect quality of life. Accurate assessment of anxiety in ASD is crucial in the behavioral management of autistic children. Most of the anxiety assessment measures are developed for non-ASD and or for the Western population. In Pakistan, assessment of anxiety in children with ASD is a huge concern, specifically due to the paucity of research and shortage of valid and reliable measures available in Urdu language. Understanding the need to have a psychometrically sound measure to assess anxiety in children with ASD, we aimed to translate and evaluate psychometric properties of the anxiety scale for children with ASD (ASC-ASD-C) for Pakistani population. Method ASC-ASD-C was translated by using Brislin's translation methods (Brislin, 1970; Gregoire, 2018; Beaton et. al., 2000). A cross-sectional survey consisted of demographic information sheet and Urdu-ASC-ASD-C was administered on 109 clinically diagnosed autistic children and adolescents aged 8-16 years, seeking treatment in special education schools. Descriptive and reliability statistics were analyzed using SPSS-26 and Jamovi. Results Semantic, content, technical, and conceptual equivalence were established between original English and Urdu versions of ASC-ASD-C. Exploratory factor analysis revealed the four-factor structure similar to the original English version, however, slight variations were reported in the allocation of items to corresponding factors. McDonald?s omega coefficient of the complete scale was ? = .959; ? = .897 for Uncertainty; ? = .771 for Performance anxiety; ? = .939 for Anxious arousal; and ? = .885 for separation anxiety subscales. Conclusions Urdu ASC-ASD-C is a valid and a reliable measure for the predictive assessment of clinical anxiety among children with ASD; future research; intervention and management of autistic children and adolescents.

Excitability and irritability in preschoolers predicts later psychopathology: The importance of positive and negative emotion dysregulation / Alecia C. VOGEL in Development and Psychopathology, 31-3 (August 2019)  

Public ISBD [article]  inDevelopment and Psychopathology > 31-3 (August 2019) . - p.1067-1083 Titre : Excitability and irritability in preschoolers predicts later psychopathology: The importance of positive and negative emotion dysregulation Type de document : Texte imprimé et/ou numérique Auteurs : Alecia C. VOGEL, Auteur ; Joshua J. JACKSON, Auteur ; Deanna M. BARCH, Auteur ; Rebecca TILLMAN, Auteur ; Joan L. LUBY, Auteur Article en page(s) : p.1067-1083 Langues : Anglais (eng) Mots-clés : depression  emotion dysregulation  exploratory factor analysis  mood lability  preschool Index. décimale : PER Périodiques Résumé : Emotion dysregulation is a risk factor for the development of a variety of psychopathologic outcomes. In children, irritability, or dysregulated negative affect, has been the primary focus, as it predicts later negative outcomes even in very young children. However, dysregulation of positive emotion is increasingly recognized as a contributor to psychopathology. Here we used an exploratory factor analysis and defined four factors of emotion dysregulation: irritability, excitability, sadness, and anhedonia, in the preschool-age psychiatric assessment collected in a sample of 302 children ages 3–5 years enriched for early onset depression. The irritability and excitability factor scores defined in preschoolers predicted later diagnosis of mood and externalizing disorders when controlling for other factor scores, social adversity, maternal history of mood disorders, and externalizing diagnoses at baseline. The preschool excitability factor score predicted emotion lability in late childhood and early adolescence when controlling for other factor scores, social adversity, and maternal history. Both excitability and irritability factor scores in preschoolers predicted global functioning into the teen years and early adolescence, respectively. These findings underscore the importance of positive, as well as negative, affect dysregulation as early as the preschool years in predicting later psychopathology, which deserves both further study and clinical consideration.
