Evaluation of the Psychometric Properties of the Scale A-ONE: An Italian Cross-Sectional Study.
Margherita Cerone, Marco Tofani, Giovanni Fabbrini and 6 others
PMID 33824630WHAT IT FOUND
In 70 Italian adults with brain disorders, A-ONE daily-living scores were stable when rated by trained occupational therapists and matched Barthel scores except communication.
The communication domain tracked Barthel scores poorly, so it can support OT assessment, not prove treatment works.
Key findings
01The study evaluated 70 people with neurological disorders, aged 60 to 89 years.
02When the same rater assessed patients one day later, agreement across domains ranged from 0.984 to 0.997; when two certified occupational therapists rated the same patient together, agreement ranged from 0.979 to 0.998.
03The communication domain had a value of 0.634 for item consistency and a value of 0.261 for its association with the Barthel index.

What it does not show
The study included only 70 Italian patients aged 60 to 90 with neurological CNS disorders, and excluded people with other medical conditions or comorbidities. The paper reports only the Functional Independence scale, not the Neurobehavioral Impairment scale. Responsiveness was measured in only 36 patients because only they received occupational therapy. The small sample size does not allow differences between populations to be understood. The Barthel index was used as the comparison measure, but it does not measure communication, so the communication domain result is hard to interpret against that standard. Only certified occupational therapists performed the ratings, so results may not apply to therapists without A-ONE training.
The easy way to misread this
Do not read this as evidence that the A-ONE improves patient outcomes. It was tested in 70 Italian adults aged 60 to 89, and the paper reports only the Functional Independence scale, not the Neurobehavioral Impairment scale.
