Hypothesis
The prevalence defined by the WGSS would be lower than that of the EDM overall as well as by sub-groups of different demographic backgrounds because of the narrower scope of the WGSS.
Conclusion
The WGSS in the CSLC had a lower prevalence compared to the EDM, primarily due to its narrower scope and less susceptibility to aging.
Supporting Evidence
- The WGSS defined prevalence was 10.7% and the EDM defined prevalence was 13.1%.
- Older age was associated with a disagreement that lowered the WGSS prevalence.
- Younger age was associated with a disagreement that increased the WGSS prevalence.
- Approximately 12% of respondents showed disagreements in their responses between the two measures.
Takeaway
This study looked at two ways to measure disability in Japan and found that one method showed fewer people with disabilities than the other, especially among older adults.
Methodology
A cross-sectional analysis using secondary data from the comprehensive survey of living conditions (CSLC) in Japan.
Potential Biases
Potential selection bias due to exclusion of individuals with disabilities who could not participate in the survey.
Limitations
The study may have underestimated the prevalence due to lack of reasonable accommodation for PWD and reliance on self-reported data.
