Psychometric Properties of the Parent-Rated Anxiety Scale in Spanish Individuals with Autism Spectrum Disorder

This validation study examined the Parent-Rated Anxiety Scale (PRAS-ASD) in 221 Spanish-speaking children with autism (mean age 8.6 years), finding strong internal consistency, test-retest reliability, and meaningful correlations with related constructs. The scale demonstrated valid measurement of anxiety across varying severity levels of autism and intellectual disability, though future research should examine invariance across demographic groups.
