The reliability and validation of simplified version
Tucker-Lewis
Due to the 23 items removed, the overall Cronbach’s alpha coefficient for simplified version was 0.87 (95%CI: 0.86–0.88), slightly lower than that of original version (0.90, 95%CI: 0.89–0.90), but still considered better reliability (Reliability of the original version and the simplified version of the Chinese Resident Health Literacy Scale in Sample B.The results in Goodness-of-fit of the CFA models of the original version and the simplified version of the Chinese resident health literacy scale in Sample B.CFI, Comparative fit index; TLI, Tucker-Lewis index; GFI, Goodness of Fit Index; RMSEA, root mean square error of approximation.*modified original version with five specified error covariances: A01 with A03; A09 with A10; B18 with B20; C06 with C10; D01 with D02.**modified simplified version with two specified error covariances: A01 with A03; D01 with D02.The test information and measurement error curves in simplified version.
