So, Pety; Greaves-Lord, Kirstin; van der Ende, Jan; Verhulst, Frank C.; Rescorla, Leslie; de Nijs, Pieter F. A. – Autism: The International Journal of Research and Practice, 2013
This study evaluated the ability of the Child Behavior Checklist and the Teacher's Report Form to identify children with autism spectrum disorders (ASD), using a sample of children with ASD (n = 458), referred children without ASD (n = 1109) and children from the general population (n = 999). A ten items ASD scale was constructed using half of the…
