Note: This table only includes studies that stated a domain was an area of strength or weakness. Studies that just indicated a domain as higher or lower in comparison to one another were not included.
a
Most studies of adaptive behavior using the VABS have not examined the motor skills domain because the samples were older than 60 months.
