The alliance of adaptive behavior and social competence: an examination of relationship between the scales of Independent Behavior and the Social Skills Rating System.

The team gave two checklists to elementary students with disabilities. One was the Scales of Independent Behavior. It tracks daily living skills like brushing teeth or using the bus. The other was the Social Skills Rating System. It tracks skills like sharing or following directions.

They wanted to see if scores on the two forms move together. If they do, both tools are likely measuring related parts of real life.

The numbers lined up in the middle range. Higher adaptive scores went with higher social scores. This match gives you confidence that both tools are valid for K-3 students with disabilities.

Wang et al. (2011) later asked the same question in preschoolers with autism. They still found good reliability, but warned the SSRS may miss small day-to-day changes after you start teaching.

Levin et al. (2014) looked at three autism severity tools in preschoolers. They saw only partial overlap, much like the middle-range links found here.

Wanchisen et al. (1989) compared two older adaptive scales in autistic youth. They also found solid concurrent validity, setting the stage for this newer SIB-SSRS pairing.

You can feel safe using either the SIB or the SSRS for first-round screening in early elementary grades. If a child scores low on one, check the other domain before writing goals. The moderate link means you are not double-testing, but you are also not missing a gap.
