Health status of civil servants in Tianjin and reliability and validity of Sub-Health Measurement Scale Version 1.0(SHMS V1.0)

ObjectiveTo assess the health status of civil servants in Tianjin and the reliability,validity of SHMS V1.0.MethodsThe participants were randomly selected from civil servants in Tianjin with stratified cluster sampling method and investigated with SHMS V1.0 and MOS 36-item short-form health survey(SF-36)scales among 3 610 valid participants.The reliability and validity of SHMS V1.0 was evaluated by calculating the test-retest reliability,split-half reliability,Cronbach's alpha coefficient,construct validity,and criterion-related validity.Results The mean score of SHMS V1.0 was 68.482±11.726 with the scores of 69.400±13.345,68.972±14.380,and 66.400±14.217 for physical,psychological,and social sub-scales,respectively.The test-retest reliability of SHMS V1.0 was 0.853;the split-half reliability was 0.959,and Cronbach'sα coefficient was 0.928.Factor analysis showed eight components,explaining 64.43% of total variance.Factor analyses demonstrated that the results were consistent with the original theoretical conception of SHMS V1.0.The Spearman correlation coefficient between SHMS V1.0 and SF-36 was 0.786(P<0.001).ConclusionThe sub-health is prevalent among the civil servants in Tianjin city.SHMS V1.0 is good in reliability and validity and is suitable for sub-health evaluation among Tianjin civil servants.
