Hypothesis
Are measures of disability and health-related quality of life interchangeable when compared to disease-related impairments?
Conclusion
Patient's impairments are better reflected in disability measures than in health-related quality of life instruments.
Supporting Evidence
- The relationship between impairment and disability was stronger than between impairment and HRQL.
- Impairment measures were significantly higher related with the physical component of HRQL than with the mental component.
- The study included 31 studies with an average sample size of 401 persons.
Takeaway
This study found that how sick someone feels affects their ability to do daily activities more than it affects how happy they feel about their life.
Methodology
A systematic literature search was conducted, and studies were included if they reported associations between impairment, disability, and health-related quality of life.
Potential Biases
There was no clear indication of publication bias.
Limitations
The study may not have included all relevant studies due to the complexity of distinguishing between impairment, disability, and HRQL.
Participant Demographics
The studies included a variety of conditions such as arthritis, multiple sclerosis, and Parkinson's disease.
