Methodology
Methodology notes
Autism spectrum disorder (ASD) is defined as a constellation of behaviors indicating social, communicative, and behavioral impairment or abnormalities. The essential features of ASD are (a) impaired reciprocal social interactions, (b) delayed or unusual communication styles, and (c) restricted or repetitive behavior patterns.
History
Comparable HP2020 objective
Modified, which includes core objectives that are continuing from Healthy People 2020 but underwent a change in measurement.
Changes between HP2020 and HP2030
This objective differs from Healthy People 2020 objective MICH-29.1 in that objective MICH-29.1 tracked children aged 10 to 35 months who had been screened for developmental delays, while this objective tracks children aged 9 to 35 months who have received developmental screening.
1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
