| Résumé : |
The broad autism phenotype is the phenotypic expression of the primary characteristics of autism. However, currently available tests do not agree with the two-domain operationalization of broad autism phenotype or autism, and their internal structure has shown instability across applications. This study presents the Broad Autism Phenotype-International Test, the first such test designed to target a two-domain operationalization in Spain and the United Kingdom. A broad pilot study was conducted in three community samples, two from Spain (ES1, N = 970; ES2, N = 460) and one from the United Kingdom (N = 530). The Broad Autism Phenotype-International Test consists of 20 items distributed into the SOCIAL-BAP and RIRE-BAP dimensions, representing the seven autistic subdomains. Common factor approaches were used to find a simple and invariant factor structure between countries. The Broad Autism Phenotype-International Test presents full metric invariance between two Spanish samples, partial invariance between countries, and adequate omega reliability estimation. Evidence-based results on the relationships of the SOCIAL-BAP and RIRE-BAP to other variables (the Social Responsiveness Scale-2 and the Broad Autism Phenotype Questionnaire) support the interpretation of its scores for the intended uses. The evidence provided in this article shows that the Broad Autism Phenotype-International Test functions adequately compared to other available broad autism phenotype tests, such as the Broad Autism Phenotype Questionnaire. Lay abstract The broad autism phenotype refers to a group of behaviors related to autism spectrum disorder, but that appear to a lesser extent. Its assessment has been performed through outdated broad autism phenotype/autism spectrum disorder definitions and tests. To address this problem, this study presents the development of a new test, the Broad Autism Phenotype-International Test, a 20-item measure consisting of two dimensions, SOCIAL-BAP and RIRE-BAP, targeting the two-domain operationalization of autism spectrum disorder in Spain and the United Kingdom. Unlike the Broad Autism Phenotype Questionnaire, this test received empirical support as a quick and effective broad autism phenotype measure that can facilitate both broad autism phenotype/autism spectrum disorder research and interventions. This is the first step to studying the BAP in several Spanish and English-speaking countries. |
