Exploratory study of predictors of decreased ability to perform activities of daily living in people living with hand osteoarthritis
Authors' conclusion
The findings suggest that variables representing body functions, perceived health, and quality of life do not predict ADL ability among people living with hand OA.
Study context
- Population
- Adults with hand osteoarthritis (OA) in the COLOR trial
- Participants
- 62 adults
- Outcome
- Clinical predictors of decreased ADL ability: self-reported (ADL Interview) and observed (Assessment of Motor and Process Skills)
Methodological detailsexploratory, independent add-on to the COLOR randomised controlled trial, correlational analyses and prediction models
- Exploratory
- Independent add-on to the COLOR randomised controlled trial
- Correlational analyses and prediction models
Main finding
As reported in the abstract
Predictors of ADL ability
- Prediction model root mean square error (RMSE), observed activities of daily living (ADL) motor ability
- 0.3
- Prediction model RMSE, observed ADL process ability
- 0.2
- Prediction model RMSE, self-reported ADL ability
- 0.6
- Variance explained, observed ADL motor ability (adjusted Rs = 0.163)
- 16%
- Variance explained, observed ADL process ability (adjusted Rs = 0.120)
- 12%
Observational data: associations, not effects.
