A lengthier list of autism screening tools, especially more in depth tools not designed for a primary care office visit, are available in the article, Identification and Evaluation of Children With Autism Spectrum Disorders by Chris Plauché, Scott M. Myers and the Council on Children With Disabilities. Pediatrics 2007; 120: 1183-1215.
Another useful resource is accessible in the 2006 AAP Policy statement, Identifying Infants and Young Children With Developmental Disorders in the Medical Home: An Algorithm for Developmental Surveillance and Screening. Council on Children With Disabilities et al. Pediatrics, 2006; 118: 405-420.
