“…The BAPQ was developed to measure broad autism phenotypes (BAP) in non-autistic relatives of autistic individuals, with high sensitivity for detecting BAP when comparing relatives of autistic individuals to non-autistic controls (22,38). Although the BAPQ categorizes behaviors into three domains, recent work, including the current study, point to the possibility that shared mechanisms contribute to dysfunction across each domain.…”

“…We applied sparse canonical correlation analysis (sCCA), a well established and popular method to find associations across multiple sets of multivariate data. The main goal of sCCA is to find pairs of linear combinations which would maximize the correlations between two datasets with a sparseness parameter control, and how many dimensions are required for those correlations (38). The pairs of linear combinations represent canonical variables, and the correlation between them are defined as canonical correlations.…”

Autism spectrum disorder (ASD) is most often defined by social communication challenges and behavioral rigidity, but executive function deficits have long been considered potential contributors to autism-related impairments across these domains. Autism is a spectrum, with a broad range of phenotypes presenting below the diagnostic threshold, raising the possibility that variability in executive function may contribute to individual differences in autistic traits in the general population. Value based decision making tasks access aspects of executive function, and critically are amenable to computational approaches to dissect the latent variables that most contribute to individual differences in cognition. We capitalize on this approach to uncover the relationship between autistic traits as measured by the Broad Autism Phenotype Questionnaire (BAPQ) and explore-exploit balance in a three-armed restless bandit decision making task in a large (1001 participants) sample. We find that the BAPQ aloof subscale, which primarily describes social behavior related phenotypes, most strongly explains changes in choice behaviors, including sensitivity to outcomes, changes in choice flexibility, and level of exploration as inferred from a Hidden Markov Model. Canonical correlation analysis reveals that the strongest loading for these non-social reward related measures are in fact socially coded items. These findings suggest that different aspects of executive function challenges may be related to social and nonsocial autism-related behaviors in the general population, and that social components of behavior produce measurable differences in nonsocial tasks.

Applying a Rasch model to the Broad Autism Phenotype Questionnaire: item severity analysis and differential test functioning of the English and Spanish versions

et al. 2022

The broad autism phenotype (BAP) represents the elevated but nonclinical levels of autism-related expressions expanding them beyond the disorder threshold towards the general population and it is assessed worldwide using the Broad Autism Phenotype Questionnaire. In this study, we applied a Rasch item response approach to the Spanish and the English BAPQ versions. This approach allows us to test the proper functioning of each version, estimate which BAP behaviours are more likeable at different levels of severity, and study whether BAPQ item’s severities and orders could be considered equivalent between both versions. A Spanish community sample of 970 participants and an English of 533 ones completed either the Spanish or the English version of the BAPQ. The results revealed a lack of unidimensionality of the Pragmatic Language subscale in both tests and the Rigid subscale in the English version. Both Aloof subscale versions and the Spanish Rigid demonstrated adequate properties but with several items showing differential functioning in the case of Aloof. We conclude by highlighting the necessity of BAP measurements paralleling the current autism spectrum disorder structure, following the severity-dimensional conceptualization (behaviours are continuously distributed according to their severity), and suitable for being adapted to different languages.
