The results were quite disappointing, revealing that more than 60% of children were not correctly screened for autism. The MCHAT, which is widely accepted as a valid screening tool for autism, was recently examined in a large-scale community-based study published in Pediatrics. The most popular screening tool is the Modified Checklist for Autism in Toddlers (MCHAT), which was developed to assess children between 16 and 30 months of age. Screening tools have been developed to determine whether or not a child should receive extensive evaluation for autism. The main goal of screening, especially during the first two years of development, is to begin early intervention services. The American Academy of Pediatrics urges that all children be evaluated for autism between the ages of 18 months and 24 months. Examples include anxiety, gastrointestinal distress, immunological and metabolic impairment, and sleep problems. It is now becoming clear that physical symptoms often associated with autism, including medical comorbidities, should be included as part of an autism diagnosis. These include the Autism Diagnostic Interview (ADI), the Autism Diagnostic Observation Scales (ADOS), the Child Autism Spectrum Test (CAST), the Childhood Autism Rating Scale (CARS), and the Gilliam Autism Rating Scale (GARS).

Additional changes to the criteria for autism were made in DSM-IV (1994), DSM-IVR (2000), and DSM-V (2013).Ĭurrently, several diagnostic assessment tools are based on the criteria established by the American Psychiatric Association. Seven years after that, autism was more clearly defined in the revised edition (DSM-IIIR, 1987). It was not until 12 years later that “infantile autism” had its own category (DSM-III, 1980). In their first mention of autism, the American Psychiatric Association described children who exhibited “autistic, atypical and withdrawn behavior,” but this was part of the diagnostic criteria for childhood schizophrenia ( Diagnostic and Statistical Manual, DSM-II, 1968). Unfortunately, most investigations have included children on the entire autism spectrum rather than those clinically assessed as having classical autism or Kanner syndrome.

Rimland published a revised version which appeared in later editions of his book and is still distributed and scored free of charge by the Autism Research Institute. The first version, titled the Diagnostic Checklist for Behavior-Disturbed Children, appeared in his 1964 seminal book Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior. Bernard Rimland developed a checklist for professionals and parents that was designed specifically to diagnose Kanner’s syndrome or classical autism.
