PMID 37877957WHAT IT FOUND
The Greek Modified Barthel Index was stable and matched other daily function scores well in stroke and spinal cord injury rehab, but it did not fit as a single score.
Use transfers and daily activities plus mobility separately.
Key findings
01The original single-factor model was rejected, and the two-factor model was adopted.
02Scores were very highly related to the Katz Index and highly related to the SF-36 physical functioning score.
03The mobility subscale had a floor effect, with 21% of patients at the lowest possible score, above the 15% threshold used.

What it does not show
Inter-rater reliability was not examined, so the study does not show whether different clinicians would score the same patient similarly. Only 41 of the 100 patients were reassessed after 3 days, and the authors said this test-retest sample was smaller than ideal. Patients were inpatients and outpatients, and time since injury ranged from 1 month to 15 years, so scores may reflect different rehabilitation stages. There were fewer women than men, and the authors considered the sample representative of Greek neurorehabilitation patients.
Declared interests
The authors declared no conflict of interest with any financial organization regarding the material discussed.
The easy way to misread this
Do not treat the Modified Barthel Index total score as a single measure of a single underlying ability. The original single-factor model was rejected, and Rasch analysis found misfit for stair climbing, ambulation, bathing and personal hygiene.
