Abstract: Objective　To analyze the reliability and validity of Sub-health Measurement Scale Version 1.0（SHMS V1.0） in measuring the sub-health status of urban residents in Anhui Province.Methods　We carried out this study from November 2016 to March 2017.The 1 150 urban residents（selected based on male to female ratio of 1∶1） enrolled in accordance with the inclusion and exclusion criteria of the study，were from a stratified random sample of 3 prefecture-level cities of Anhui Province（400 from Hefei，400 from Tongling，and 350 from Fuyang）．We used a self-designed Sub-health Questionnaire（consisting of Urban Resident Demographic Questionnaire and SHMS V1.0） for collecting the data about sub-health.Psychometric properties of SHMS V1.0 including the reliability（internal consistency reliability and split-half reliability），content validity（item-dimension correlation，correlation between dimension and subscale，Cronbach's ɑ for each dimension，dimension-total correlation） and structural validity（exploratory factor analysis and confirmatory factor analysis） were assessed.Results　A total of 1 078（93.74%） residents returned responsive questionnaires.The Cronbach's ɑ for SHMS V1.0，physiological sub-health scale（PS），mental sub-health subscale（MS），and social sub-health subscale（SS） was 0.928，0.847，0.875 and 0.857，respectively.The Spearman-Brown coefficients for them were 0.847，0.749，0.809 and 0.742，respectively.The Guttman coefficients for them were 0.847，0.745，0.807 and 0.731，respectively.The item-to-own-dimension correlation coefficients of SHMS V1.0 ranged from 0.711 to 0.901（P<0.05）．The correlation coefficients of dimension to its corresponding subscale were 0.642-0.906（P<0.05）．The Cronbach 's ɑ of each dimension is greater than the correlation coefficients of this dimension with other dimensions or the SHMS V1.0（P<0.05）．The KMO of SHMS V1.0=0.901，the Bartlett's spherical test χ2=8 753.858，and the degrees of freedom was 595（P<0.001），indicating that it was suitable for factor analysis.Totaled 8 common factors were extracted from exploratory factor analysis，explaining 63.319% of the total variance，and each item had a large loading value on one of the common factors（>0.400）．Confirmatory factor analysis confirmed that the fitting effect of the final model was ideal：the degrees of freedom ratio（CMIN/DF）=2.009，the normed fit index（NFI）=0.858，the relative fit index（RFI）=0.835，the incremental fit index（IFI）=0.907，tucker-lewis index（TLI）=0.891，comparative fit index（CFI）=0.906，root mean square error of approximation（RMSEA）=0.055.Conclusion　SHMS V1.0 could accurately，reliably and sensitively measure the sub-health status of Anhui urban residents，demonstrating its good reliability and validity，so it can be used for further study of the status and associated factors of sub-health among this population.
