Psychometric Properties of the Autism-Spectrum Quotient for Assessing Low and High Levels of Autistic Traits in College Students / Jennifer L. STEVENSON in Journal of Autism and Developmental Disorders, 47-6 (June 2017)
[article]
Titre : Psychometric Properties of the Autism-Spectrum Quotient for Assessing Low and High Levels of Autistic Traits in College Students Type de document : Texte imprimé et/ou numérique Auteurs : Jennifer L. STEVENSON, Auteur ; Kari R. HART, Auteur Article en page(s) : p.1838-1853 Langues : Anglais (eng) Mots-clés : Autism-Spectrum Quotient Autistic traits Internal consistency Test–retest reliability Scoring method Subscale scores Index. décimale : PER Périodiques Résumé : The current study systematically investigated the effects of scoring and categorization methods on the psychometric properties of the Autism-Spectrum Quotient. Four hundred and three college students completed the Autism-Spectrum Quotient at least once. Total scores on the Autism-Spectrum Quotient had acceptable internal consistency and test–retest reliability using a binary or Likert scoring method, but the results were more varied for the subscales. Overall, Likert scoring yielded higher internal consistency and test–retest reliability than binary scoring. However, agreement in categorization of low and high autistic traits was poor over time (except for a median split on Likert scores). The results support using Likert scoring and administering the Autism-Spectrum Quotient at the same time as the task of interest with neurotypical participants.

Titre : Reliability and validity of the Psychoeducational Profile-third edition Caregiver Report in children with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Chung-Pei FU, Auteur ; Kuan-Lin CHEN, Auteur ; Mei-Hui TSENG, Auteur ; Fu-Mei CHIANG, Auteur ; Ching-Lin HSIEH, Auteur Année de publication : 2012 Article en page(s) : p.115-122 Langues : Anglais (eng) Mots-clés : Psychoeducational Profile-third edition Caregiver Report Autism Spectrum Disorders Internal consistency Inter-respondent reliability Convergent validity Index. décimale : PER Périodiques Résumé : The aim of this study was to examine the internal consistency, inter-respondent reliability, and convergent and divergent validity of the Psychoeducational Profile-third edition Caregiver Report (PEP3-CR) in children with Autism Spectrum Disorders (ASD). We examined the internal consistency on 66 mothers of children with ASD who completed the PEP3-CR. Inter-respondent reliability was examined on 46 pairs of mothers and fathers who completed the PEP3-CR independently within one week. Moreover, 64 children were administered the Psychoeducational Profile-third edition Performance Test (PEP3-PT) and 20 children and their parents were administered the Childhood Autism Rating Scale (CARS) and the Vineland Adaptive Behavior Scale (VABS) to examine the convergent and divergent validity of the PEP3-CR. The Cronbach's alpha of the PEP3-CR subtests, ranging from 0.83 to 0.85, indicated sufficient internal consistency. The intra-class correlation coefficient (ICC) of the two parents, ranging from 0.66 to 0.79, indicated moderate inter-respondent reliability. The correlations between the PEP3-PT, CARS, VABS and the PEP3-CR supported the convergent and divergent validity of the PEP3-CR. Therefore, the PEP3-CR is a reliable and valid caregiver report for assessing adaptive functioning and autistic behaviors in children with ASD.

CROUDACE, Auteur Article en page(s) : p.2855-2865 Langues : Anglais (eng) Mots-clés : Internal consistency Meta-analysis Psychometrics Questionnaires Reliability generalisation Reproducibility of results Score stability Index. décimale : PER Périodiques Résumé : The Childhood Autism Rating Scale (CARS) is a popular behavior-observation instrument that was developed more than 34 years ago and has since been adopted in a wide variety of contexts for assessing the presence and severity of autism symptomatology in both children and adolescents. This investigation of the reliability of CARS scores involves meta-analysis and meta-regression of empirical data from reports of original research that made use of CARS between 1980 and 2012. Findings of good internal consistency (.896, 95 % CI .877–.913) and good interrater reliability (.796, 95 % CI .736–.844) support use of CARS at least in early-phase, exploratory research. Evidence of heterogeneity among literature data indicates that reliability is a property of CARS scores and is not intrinsic to the instrument itself. As the first of its kind pertaining to autism, this investigation provides guidance for reviews of other instruments’ ratings.

GUASTELLA, Auteur Année de publication : 2019 Article en page(s) : p.1101-1111 Langues : Anglais (eng) Mots-clés : Whodas autism spectrum disorder disability internal consistency validity Index. décimale : PER Périodiques Résumé : The World Health Organization Disability Assessment Schedule II (WHODAS-II) is one of the most widely used generic assessments for measuring disability levels in both clinical and nonclinical populations, with sound psychometrics that is also aligned with the International Classification of Functioning framework. However, its psychometric properties have not been explored extensively in individuals with autism spectrum disorder (ASD). This study examined the psychometric properties of the 36-item and 12-item Self-Report WHODAS-II from 109 individuals diagnosed with ASD and without intellectual disability (IQ >/= 70). Participants were consecutively recruited from the Brain and Mind Centre in New South Wales, Australia. The WHODAS-II showed adequate internal consistency for all domain scores (alpha = 0.78-0.97 for 36-item) and for the summary scale (alpha = 0.95 for 36-item; 0.86 for 12-item). All items also exhibited satisfactory correlations with their respective domain (r = 0.39-0.94 for 36-item) and summary scores (r = 0.42-0.71 for 36-item; 0.42-0.67 for 12-item), except item 4.5 "sexual activity" from the 36-item WHODAS-II (r = 0.19). Concurrent validity was shown by moderate correlations between similar constructs across the WHODAS-II and the World Health Organization Quality of Life BREF (Ps < 0.05). The second-order 7-factor model showed the best fit for the 36-item WHODAS-II, while the second-order 6-factor model demonstrated an acceptable fit for the 12-item WHODAS-II. The model fit could be improved with some modifications. The Schmid-Leiman transformation further confirmed the appropriateness of the second-order factor structure. Overall, the results indicated that the WHODAS-II is a viable generic self-report measure for disability in autistic individuals without ID. Autism Res 2019, 12: 1101-1111. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The majority of autistic people have a disability with a profound or severe limitation in their core activities. However, there is currently limited research identifying reliable and valid self-report measures for disability in the autistic population. This study examined the psychometric properties of the World Health Organization Disability Assessment Schedule II (WHODAS-II) from 109 autistic individuals without intellectual disability. Our results suggest that the WHODAS-II is a viable generic self-report measure for disability in autistic individuals.
