Autism spectrum condition (ASC) is a neurodevelopmental condition characterized by a spectrum of neuropsychological and behavioral impairments ranging from mild to severe. Formal diagnostic assessments primarily rely on a comprehensive evaluation of behavioral and developmental factors. However, the self-report assessments currently used have limitations which threaten the scales’ reliability and validity. The purpose of this study was to develop and assess the psychometric properties of the Autism Spectrum Trait Scale (ASTS), a new self-report scale developed to detect ASC in adults. Exploratory factor analysis (EFA) (n = 764) was conducted to develop the factor structure, and confirmatory factor analysis (CFA) (n = 754) was performed to determine model fit. The results indicated a stable six-factor model with good model fit, metric measurement invariance, and relatively high sensitivity and specificity. These findings provide evidence for the utilization of the ASTS as a component of assessment for ASC in adults.
