Research Article: Psychometric Properties of the Chinese Version of the Comprehensive Autistic Trait Inventory

Date Published: 2023-06-15

Abstract:
A systematic review reveals an increase in the global prevalence of autism. Autism spectrum disorder (ASD) affects approximately % of children worldwide, with the prevalence of autism in China close to that in the West. ASD is a neurodevelopmental disorder that is defined by deficits in social communication and restricted, repetitive patterns of interests and behaviors. The severity and scope of these core behavioral traits can vary based on where an individual falls on the autism continuum. Autistic traits refer to personality traits, social interaction characteristics, and behaviors similar to autism, first observed among parents and relatives of autistic children, continuously distributed in individuals on the autism spectrum, and the general population.– Autistic traits can be considered a sixth factor of personality in addition to the Big Five., Increasing numbers of studies have found that autistic traits are prevalent in the general population,– indicating that the construct of autism might form a continuum in the general population based on trait-like characteristics. More and more studies have demonstrated the continuum model. According to the twin concordance study, autistic traits and ASD may share a genetic etiology,, and it is estimated that the heritability of autistic traits is .–.. Substantial and replicable etiological overlap between ASD and typical variations in social and communication abilities among the general population was found using large ASD consortiums and population-based resources through linkage disequilibrium score regression and de novo variant analysis. Using a dual Weibull mixture model, researchers provide perspectives on how autism traits are distributed along a continuum. The meta-analysis of four population-based genome-wide association studies investigating autistic-like traits in the general population has shown the role of immune-related genes in specific autistic-like traits. More and more refined evidence demonstrates that the continuum view of autistic traits in the general population merits further research.,
