School refusal is more prevalent in children on the autism spectrum than among their peers. The function of school refusal can be explored using the school refusal assessment scale--revised (SRAS-R) but its relevance to children on the spectrum has not been investigated. Parents of 121 children ("M" age 11.9 years) on the autism spectrum completed the SRAS-R and provided feedback on it applicability. Confirmatory factor analysis suggests unsuitability of the original four-factor structure proposed for neurotypical students. Only 41.7% of parents considered the questionnaire an adequate method for reporting on school refusal in children on the autism spectrum with the majority (90%) identifying additional questions to evaluate factors associated with school refusal in autism.
