Immediately afterward, you code the behaviours observed. As you administer activities you observe the examinee and take notes. Standardised Administration, Coding and ScoringĮach ADOS-2 module has its own Protocol Booklet which structures the administration and guides you through coding and scoring. Module 4-for verbally fluent older adolescents and adultsĮach module engages the examinee in a series of activities involving interactive stimulus materials (all included in the ADOS-2 Kit).Module 3-for verbally fluent children and young adolescents.Module 2-for children of any age who use phrase speech who are not verbally fluent.Module 1-for children 31 months and older who do not consistently use phrase speech.Toddler Module-for children between 12 and 30 months of age who do not consistently use phrase speech.The individual being evaluated is given only one module, selected on the basis of his or her expressive language level and chronological age. The ADOS-2 includes five modules, each requiring just 40 to 60 minutes to administer. By observing and coding these behaviours, you may obtain information that informs diagnosis, intervention, treatment planning and educational placement. Like its predecessor, the ADOS-2 is a semi-structured, standardized assessment of communication, social interaction, play and restricted and repetitive behaviours.
It may be used to evaluate almost anyone suspected of having ASD-from 1-year-olds with no speech to adults who are verbally fluent. 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. This revision improves an instrument already viewed as the "gold standard" for observational assessment of autism spectrum disorders (ASDs). Authors: Catherine Lord, PhD Michael Rutter, MD.
