M-CHAT: Autism Questionnaire

The M-CHAT is an expanded American version of the original CHAT from the U.K (Baron-Cohen et al., 1992; 1996). The M-CHAT has 23 questions using the original nine from the CHAT as its basis. The goal of the ongoing M-CHAT research is to demonstrate adequate psychometric properties of the M-CHAT (sensitivity, specificity, positive and negative predictive power).

The M-CHAT is available for clinical and research use, withthe following caveats:
  1. Clinical use should proceed with caution, given that the current
    scoring system is designed to maximize sensitivity (i.e., identify as
    many children with autism spectrum disorders as possible), which
    results in a number of false positive cases (i.e., children who will
    not be diagnosed with an autism spectrum disorder, although they fail
    the M-CHAT). Once cross-validation of the M-CHAT iscomplete, the
    scoring may be revised.
  2. The M-CHAT is not designed to detect all possible developmental
    disorders. Any parents who have concerns about their child should see
    their child’s physician, regardless on the child’s score on the M-CHAT.

Not all children who fail the checklist will meet criteria for a diagnosis on the autism spectrum. However, children who fail the checklist should be evaluated in more depth by the physician or referred for a developmental evaluation with a specialist.
