A system of assessment for adaptive behavior, social skills, behavioral function, medication side-effects, and psychiatric disorders.

Katz et al. (2003) built a one-stop informant interview. It covers adaptive skills, social skills, behavior function, med side-effects, and mental health.

The battery is meant for adults with intellectual disability. One caregiver answers all sections. The goal is a cheap, wide-angle snapshot before treatment planning.

The paper does not give outcome data. It simply lays out the tool and says it saves time and money.

DiStefano et al. (2020) extends this idea. They warn that people with severe-profound ID often floor out on standard items. They add tips like adapting language and using yes-no cards.

Hoyle et al. (2022) seem to contradict the 2003 paper. They say direct observation is scarce and needed for med effects. In truth, both papers agree: start with a quick informant screen, then add direct measures if meds change.

Hilton et al. (2010) zoom in on the side-effect part. They back the 2003 choice to include a med scale, but push for structured forms like MEDS or DISCUS for finer tracking.

You can copy the 2003 battery today. Run it during intake to flag risks in five zones at once. If scores hint at med issues, add the 2010 scales and direct data the 2022 review calls for. This keeps your assessment both broad and deep without extra staff hours.
