The test of occupational stress inventory revised edition

Abstract

Objective To test reliability and validity of occupational stress inventory revised edition(OSI R). Methods 319 participants were sampled from various kinds of occupations,such as factory,office,school,service and commerce,etc with randomized cluster sampling.The inter item consistency,split half reliability and retest reliability were used to test the reliability of OSI R;the Pearson's correlation analysis was used to test the item differentiation of OSI R;the factor analysis and multi regression analysis were used to test the structure and content validity. Results α coefficients of OSI R(0.59～0.86) were consistent with Osipow's results(0.70～ 0.93) indicating OSI R had a good homogeneity;the correlation coefficient retest reliability( P 0.05) of OSI R was 0.95, implying OSI R had good retest reliability;the result of half split reliability test showed that the correlation coefficient of the inventory was 0.78,meanwhile the correlation coefficients of three questionnaires were ranged from 0.76 ～0.84;the correlation coefficient among items ranged from 0.44～0.79( P 0.01);the correlation coefficients of OSI R and items ranged from 0.14～0.74 ( P 0.05),while the correlation coefficients of OSR I and items were 0.40～0.86,indicating that the interference among OSI R items was little;the results of factor analyses and multi regression showed that there was a good structure and content validity in three questionnaires of OSI R. Conclusion OSI R may be used as an ideal tool for studying the occupational stress in China after proper revision.
