Reliability and Validity of the Chinese Version of SF-36 Scale in Guangdong Occupational Rehabilitation
Abstract
Objective:To evaluate the reliability and validity of the Chinese version of SF-36 scale in occupational rehabilitation patients in Guangdong Province.Methods:A total of 1,129 patients who participated in occupational rehabilitation were selected and filled in the SF-36 (Chinese version) by self-filling or interviewing.Results:The physiologic function (RP) ICC was 0.670.Twice repeat evaluations showed that the IFC of the total and other seven dimensions were all greater than 0.75 (P<0.001);The Cronbach's alpha coefficients of the total and eight dimensions were all higher than 0.7;Split-half reliability coefficient was higher than 0.6 (P<0.001) and split-half reliability was higher than 0.7 in eight dimensions (P<0.001).The success rate of the pooled validity was 94.3%,and the success rate of discriminant validity was 100%.Factor analysis produced a total of two common factors. Both factors were able to explain 62.724%of the total variance and had a stronger factor load (>0.4) in the corresponding project. The social function (SF) load values on the two common factors were all higher than 0.4,suggesting that the project's significance was not clear and the scale had poor structural validity in this population.Conclusion:The Chinese version of SF-36 scale has good test-retest reliability, internal reliability, half-half reliability, set and discriminant validity, and poor construct validity in occupational injury rehabilitation workers.
