A comprehensive psychometric analysis of autism-spectrum quotient factor models using two large samples: Model recommendations and the influence of divergent traits on total-scale scores / Michael C. W. ENGLISH in Autism Research, 13-1 (January 2020)

Titre : A comprehensive psychometric analysis of autism-spectrum quotient factor models using two large samples: Model recommendations and the influence of divergent traits on total-scale scores Type de document : Texte imprimé et/ou numérique Auteurs : Michael C. W. ENGLISH, Auteur ; Gilles E. GIGNAC, Auteur ; Troy A. W. VISSER, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; Murray T. MAYBERY, Auteur Article en page(s) : p.45-60 Langues : Anglais (eng) Mots-clés : Aq Raine study autism autism-spectrum quotient autistic traits confirmatory factor analysis factor model Index. décimale : PER Périodiques Résumé : The Autism-Spectrum Quotient (AQ) is a psychometric scale that is commonly used to assess autistic-like traits and behaviors expressed by neurotypical individuals. A potential strength of the AQ is that it provides subscale scores that are specific to certain dimensions associated with autism such as social difficulty and restricted interests. However, multiple psychometric evaluations of the AQ have led to substantial disagreement as to how many factors exist in the scale, and how these factors are defined. These challenges have been exacerbated by limitations in study designs, such as insufficient sample sizes as well as a reliance on Pearson, rather than polychoric, correlations. In addition, several proposed models of the AQ suggest that some factors are uncorrelated, or negatively correlated, which has ramifications for whether total-scale scores are meaningfully interpretable-an issue not raised by previous work. The aims of the current study were to provide: (a) guidance as to which models of the AQ are viable for research purposes, and (b) evidence as to whether total-scale scores are adequately interpretable for research purposes. We conducted a comprehensive series of confirmatory factor analyses on 11 competing AQ models using two large samples drawn from an undergraduate population (n = 1,702) and the general population (n = 1,280). Psychometric evidence largely supported using the three-factor model described by Russell-Smith et al. [Personality and Individual Differences 51(2), 128-132 (2011)], but did not support the use of total-scale scores. We recommend that researchers consider using AQ subscale scores instead of total-scale scores. Autism Res 2020, 13: 45-60. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We examined 11 different ways of scoring subscales in the popular Autism-Spectrum Quotient (AQ) questionnaire in two large samples of participants (i.e., general population and undergraduate students). We found that a three-subscale model that used "Social Skill," "Patterns/Details," and "Communication/Mindreading" subscales was the best way to examine specific types of autistic traits in the AQ. We also found some weak associations between the three subscales-for example, being high on the "Patterns/Details" subscale was not predictive of scores on the other subscales. This means that meaningful interpretation of overall scores on the AQ is limited.

However, some aspects of the AQ are questionable. To test its scale properties, the AQ was translated into Swedish, and data were collected from 349 adults, 130 with autism spectrum disorder (ASD) and 219 without ASD, and analysed with Rasch. Several scale properties of the AQ were satisfactory but it did not meet the criterion of a unidimensional measure of autistic traits. The Rasch analysis showed that the 50-item AQ could be reduced to a 12-item subset with little loss of explanatory power, with the potential to efficiently measure the degree to which adults with and without ASD show autistic traits.

However, the language of the questionnaire might influence non-native English speakers' answering tendency. In the current study we compared the responses on the AQ of multilingual Malaysians (96 participants filled out the AQ in English and Mandarin, and 79 participants filled out English and Bahasa Malaysia). Participants scored higher on the English AQ compared to the Mandarin AQ, whereas there was no difference between the English and Bahasa Malaysia AQ score. Analysis of the response style suggests the same person might display discrepant response styles in different languages, which seems to be related to language proficiency.

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.

JING, Auteur Article en page(s) : p.303-315 Langues : Anglais (eng) Mots-clés : autism spectrum disorder autism-spectrum quotient autistic traits children sex differences Index. décimale : PER Périodiques Résumé : A Simplified Chinese translation of the Autism Spectrum Quotient-Children's Version (AQ-C) is needed for research in mainland China. Autism Spectrum Disorder (ASD) is a condition that differs in presentation and prevalence by sex. Thus, evaluating the psychometric validity of the AQ-C in males and females is an important step in its validation. The present study aims to develop a Chinese translation of the parent-report AQ-C, and test its psychometric properties among Mandarin Chinese speaking boys and girls. A total of 1,020 non-clinical children and 134 children with ASD were assessed. Factor analyses were performed for the whole sample, as well as for girls and boys separately. A 30-item, 5-factor model (the Chinese AQ-C) showed adequate goodness of fit (root mean square error of approximation [RMSEA] = 0.037; comparative fit index [CFI] = 0.907; Tucker-Lewis index [TLI] = 0.901) for the whole sample. According to parents' reports, non-clinical boys had significantly higher scores than non-clinical girls on the Chinese AQ-C. Sex-specific factor structures were identified resulting in a 4-factor model with 32 items for girls (the Chinese AQ-Girls), and a 4-factor model with 34 items for boys (the Chinese AQ-Boys). The cut-off scores of the Chinese AQ-C, AQ-Girls, and AQ-Boys were 44.5, 42.5, and 46.5, respectively. These three Chinese versions of the AQ-C all showed satisfactory internal consistency (alpha = 0.786-0.840) and concurrent validity with the Social Responsiveness Scale (r = 0.789-0.814) for the total scale. Differences have been found in the sex-specific factor structures of the AQ-C which would be more reliable to use for future research when measuring autistic traits in the general population.

LAY SUMMARY: This study developed Chinese versions of the Autism Spectrum Quotient-Children's Version (AQ-C) in Chinese boys and girls together and separately. The AQ-C showed good psychometric properties in boys and girls together and separately. There were differences in sex-specific factor structures of the AQ-C. These results suggest that the sex-specific Chinese versions of the AQ-C provide reliable and valid measurement of autistic traits.
