High prevalence of autism spectrum disorders (ASD) has been reported in 22q11.2DS, although this has been based solely on parent report measures. This study describes the presence of ASD using a procedure more similar to that used in clinical practice by incorporating history (Social Communication Questionnaire) AND a standardized observation measure (Autism Diagnostic Observation Schedule) and suggests that ASD is not as common as previously reported in 22q11.2DS. Differences in methodology, along with comorbid conditions such as anxiety, likely contribute to false elevations in ASD prevalence and information from multiple sources should be included in the evaluation of ASD.
