Abstract Purpose The PEDI-CAT (ASD) is used to assess functioning of children and youth on the autism spectrum; however, current psychometric evidence limited. This study aimed explore reliability, validity acceptability using a large Australian sample. Methods Caregivers 134 spectrum participated in clinical assessments involving administration (ASD), Vineland-3, (Original) feedback instrument. content was compared ICF Core Sets for ASD summarize areas assessed relevance autism. Results demonstrated good excellent internal consistency test-re-test reliability. Parallel forms reliability with included significant correlations (good excellent), t -tests showed significantly higher Social/Cognitive scores version. Convergent results that most Vineland-3 core domains were correlated (poor good). Content analysis revealed covered less than half (mostly Activities Participation codes). Just over codes assigned represented ASD. Feedback measure mixed, but overall it considered user-friendly efficient. Conclusion had adequate properties as codes. However, lacks comprehensiveness when has potential overestimate functioning.
