Objective To evaluate the reliability and validity of the Quality of Working Life Scale (QWL7-32).
Methods The QWL7-32 scale was used to survey 487 drilling workers. The presence of chronic diseases was regarded as an effector for evaluating physical health, and the result of SCL-90 measurement was regarded as an effector for evaluating psychological health. The reliability and validity of the scale were statistically analyzed.
Results The results of the Pearson correlation coefficient was 0.713, the Cronbach's alpha coefficient was 0.920, and the Splithalf reliability coefficient was 0.942. The result of confirmatory factor analysis showed that the construct validity of scale was good, and the accumulative rate of 7 variances was 62.59%. The results of correlation analysis and t test showed that the validity of scale criterion was also good. In QWL7-32 scale, each dimension showed a good correlation with its relevant item but poor correlation with any other items.
Conclusion The QWL7-32 has a good reliability and validity.
