Description

Description

Although there have been numerous studies investigating the increased prevalence or "epidemic" of autism spectrum disorders (ASD), it is still not clear whether this relates to a true increase in ASD. Factors such as increased awareness by parents and clinicians, methods of reporting, and changing diagnostic criteria may account for this apparent increase. This study will analyze population-based records of ASD diagnoses which used diagnostic criteria that remained constant over time. Two datasets of ASD diagnoses will be analyzed: one from Denmark, and one from Western Australia. These datasets used different diagnostic criteria consistently (the Diagnostic and Statistical Manual of Mental Disorders (DSM) for Western Australia, and the International Statistical Classification of Diseases and Related Health Problems (ICD) for Denmark). This study will determine whether the criteria used affected the age at which ASD is first diagnosed, and thus affected the perceived incidence.

Strategic Plan Objective

Green dot: Objective has greater than or equal to the recommended funding. 1SB. Validate and improve the sensitivity and specificity of new or existing screening and diagnostic tools, including comparison of general developmental screening versus autism-specific screening tools, in both high risk and population-based samples through studies of the following community populations that are diverse in terms of age, socio-economic status, race, ethnicity, characteristics of ASD, and general level of functioning by 2012. IACC Recommended Budget: $5,400,000 over 3 years.
