Profiling Communication Ability in Dementia: Validation of a new cognitive-communication assessment tool.

Suzanna Dooley, Tammy Hopper, Rachael Doyle and 2 others

PMID 39736087

WHAT IT FOUND

The P-CAD assessment scores matched established tests for communication and cognition in people with dementia, and different therapists agreed on the ratings.

It reliably profiles communication abilities and support needs, though change over three months was not detected.

Key findings

01P-CAD scores correlated strongly with the MMSE-2 and the FLCI, indicating concurrent validity.

02Inter-rater reliability between two speech-language therapists was high for the P-CAD.

03No significant changes in P-CAD scores were found over a three-month period in a small subgroup.

What it does not show

The study could not prove the P-CAD is sensitive to change over time because the three-month window was too short to detect decline, and the sample size for retesting was small. The participants were mostly white, English-speaking individuals with Alzheimer's disease, so the results may not apply to other cultural, linguistic, or dementia subgroups. People with primary progressive aphasia were excluded.

Declared interests

The authors declare no conflicts of interest.

The easy way to misread this

Do not assume the P-CAD can detect short-term changes in communication ability. The study did not show it is responsive to change over three months, so it should not be used to track rapid progression in that timeframe.
