INTRODUCTION AND METHODS This study examined 85 parental-reports with 85 self-reports of autistic symptoms with the 84-item Coolidge Autistic Symptom Survey (CASS). The CASS covers all of the diagnostic criteria for autism spectrum disorder (ASD) in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), as no studies to date have compared the self-reports of individuals with autism with parent- or significant-other-reports of those individuals using the complete DSM-5. RESULTS The CASS-Parental-Report and CASS-Self-Report exhibited excellent internal reliability (α = 0.97 and 0.96, respectively). There was support for the hypothesis that parental-reports and self-reports would be similar (r = 0.66, p < 0.001). DISCUSSION In conclusion, the CASS should be considered a promising tool for assessing autistic symptoms from both parent- and self-perspectives.
