ABSTRACT To assess the reliability and validity of the Sub-health Measurement Scale Version 1.0 (SHMS V1.0).
A spot trial sampling of 2000 individuals was conducted to study the test-retest reliability, Cronbach alpha coefficient, split-half reliability, contract validity, content validity and criterion-related validity of SHMS V1.0.
The spot trial results indicated a test-retest reliability of SHMS V1.0 of 0.644 (P<0.001) with a Cronbach α coefficient of 0.917 and a split-half reliability of 0.831. The results showed a close correlation between each item of SHMS V1.0 and its dimension, but a low correlation between a particular item and other dimensions. The dimension score was significantly correlated to its subscale scores, but not to other subscale scores. The results of factor analysis matched the theoretical conception of SHMS V1.0. The correlation coefficient between SHMS V1.0 and SF-36 was 0.664 (P<0.001).
SHMS V1.0 has a good reliability and validity, and is a reliable and valid measurement scale for sub-health evaluation.
