Key Result

While EQ-5D-5L and SF-6Dv2 showed comparable reliability and validity, their utility values significantly differed, indicating they are not interchangeable.

Key Points

To compare the measurement properties of EQ-5D-5L and SF-6Dv2 among Chinese patients with diabetes.
Analyzed the reliability of both instruments through statistical tests.
Evaluated the validity and sensitivity of EQ-5D-5L and SF-6Dv2.
Compared utility values derived from each measurement tool.
Both EQ-5D-5L and SF-6Dv2 displayed comparable reliability, validity, and sensitivity.
Significant differences in utility values were found between the two instruments.
Findings suggest that EQ-5D-5L and SF-6Dv2 may not be used interchangeably.

Structured PICO

Population

600 Chinese patients with diabetes (90% type 2, 10% type 1), mean age 60 years, 53.67% male, recruited via quota sampling across seven geographical regions.

Intervention

EQ-5D-5L and SF-6Dv2 health-related quality of life instruments

Outcome

Measurement properties including test-retest reliability, agreement, convergent validity, known-group validity, and sensitivitypatient reported

The EQ-5D-5L and SF-6Dv2 show comparable reliability and validity in Chinese patients with diabetes, but yield different utility values and should not be used interchangeably.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

EQ-5D-5L and SF-6Dv2 showed generally comparable reliability, validity, and sensitivity in this sample of Chinese patients with diabetes. However, the utility values derived from the two instruments differed, indicating that they may not be used interchangeably. Further research is needed to evaluate and compare their responsiveness.
