[Application of SF-36 scale in the survey of quality of life of occupational disease patients].

Objective: To explore the application of the Short Form of Quality of Life (SF-36) scale in the investigation of quality of life of occupational disease patients. Methods: In May 2019, SF-36 scale was used to investigate the occupational disease patients diagnosed in Hangzhou. The reliability of the scale was evaluated by Cronbach's α coefficient, and the validity of the scale was evaluated by exploratory factor analysis. Results: The Cronbach's α coefficients of PF, RP, BP, GH, VT, SF, RE and MH were 0.937, 0.977, 0.870, 0.908, 0.815, 0.701, 0.967 and 0.863 respectively, and the half reliability coefficient α=0.905. The two factor statistics representing physiological and psychological aspects were 0.870, and the approximate chi square value was 1784.337 (P<0.01) . Compared with the national norm, the scores of each dimension of quality of life of occupational disease patients were significantly lower, and the differences were statistically significant (P<0.01) ; Compared with the scores of each dimension of quality of life of pneumoconiosis patients, the scores of PF, RP and GH of occupational disease patients were significantly higher, and the differences were statistically significant (P<0.05) . Conclusion: SF-36 scale has good reliability and validity in measuring the quality of life of patients with occupational diseases, which can be used to evaluate the quality of life of patients with occupational diseases.
