Test-Retest Reliability of a Measure of Independence in Everyday Activities: The ADL Profile.
Élisabeth Dutil, Carolina Bottari, Claudine Auger
PMID 29097964WHAT IT FOUND
The ADL Profile produced stable scores when the same therapist retested 20 people with severe TBI.
Three community tasks were less stable, so a better score on those tasks may not mean change.
Key findings
01Task scores were stable across two administrations, with agreement ranging from moderate to almost perfect.
02Community tasks were least stable, especially making a budget, calling for information, and shopping.
03The sample was 20 participants, and small samples can make agreement results unstable.

What it does not show
The sample was only 20 participants, which can make agreement results unstable. The target interval was one to two weeks, but the average interval was 22.9 days. Three tasks had only moderate agreement, and two tasks showed slightly higher scores at the second test. This may reflect familiarity or memory. The study did not show that the ADL Profile can detect real change after intervention.
The easy way to misread this
Do not use this study to say a treatment worked. It tested whether ADL Profile scores stayed the same across repeat testing in 20 people with severe TBI. It did not test treatment effects, and some community tasks may look better on retesting because of familiarity or memory.
