The Autism Diagnostic Interview-Revised (ADI-R) is a comprehensive tool used for diagnosing autism spectrum disorder, and one of its limitations is indeed the requirement for extensive training for administration and interpretation. This involves not only understanding the diagnostic criteria but also being proficient in how to conduct interviews effectively and interpret the nuanced responses that individuals with autism may provide. This expertise is crucial to ensure the reliability and validity of the diagnosis, as the misinterpretation of responses can lead to incorrect conclusions about an individual’s symptoms and needs.

While the other options suggest limitations in the ADI-R’s age applicability, specific developmental focuses, and its ability to reflect cognitive development, these do not accurately represent the primary barriers practitioners face when utilizing this tool. The method's complexity and the necessity for skilled practitioners to administer it ensure that the resulting data is meaningful and applicable for diagnostic purposes.
