How is the Cognitive Performance Scale (CPS) used in InterRAI LTCF, and what does a higher CPS imply?

• A. CPS measures mood; higher means better mood.
• B. CPS is derived from cognitive items and indicates level of cognitive impairment; a higher score means greater impairment.
• C. CPS evaluates nutrition; higher means better intake.
• D. CPS measures physical mobility; higher means more mobility.

Answer: (B)

The Cognitive Performance Scale is a global rating of a resident’s cognitive status that comes from the cognitive items in the InterRAI LTCF assessment. It reflects the level of cognitive impairment, not mood, nutrition, or physical mobility. A higher CPS score indicates greater cognitive impairment, meaning more severe difficulties with memory, attention, decision-making, and communication. This measure helps the care team identify needs, plan appropriate cognitive supports, and monitor changes over time. For example, a resident with intact memory and orientation would have a low CPS, while someone with confusion or impaired ability to understand and express themselves would have a higher CPS.
