This revision improves an instrument already viewed as “the gold standard” for the observational assessment of autism spectrum disorder (ASD). With updated protocols, revised algorithms, a new Comparison Score, and a Toddler Module, the ADOS-2 provides a highly accurate picture of current symptoms, unaffected by language. It can be used to evaluate almost anyone suspected of having ASD–from 1-year-olds with no speech to adults who are verbally fluent. Like its predecessor, the ADOS-2 is a semi-structured, standardized assessment of communication, social interaction, play, and restricted and repetitive behaviours. It presents various activities that elicit behaviours directly related to a diagnosis of ASD. By observing and coding these behaviours, you can obtain information that informs diagnosis, treatment planning, and educational placement. The individual being evaluated is given only one module, selected on the basis of his or her expressive language level and chronological age. Following the guidance provided in the manual, you choose the module that’s appropriate for the individual
