Validation of a French Canadian version of the Organizational Policies and Practices (OPP) questionnaire.

Organizational factors are potentially powerful in accounting for work-related chronic disability following a musculoskeletal disorder. This study documents the psychometric qualities of the French Canadian version of the Organizational Policies and Practices questionnaire (OPP) [1] on a population of nurses (N=124). By excluding the two items composing the ergonomic practices factor, a factorial structure identical to that obtained by the OPP's authors is obtained for the disability management policies and practices factor, the people-oriented culture factor and the safety climate factor. The internal consistency coefficients (Cronbach's alpha) are satisfactory while the coefficients intraclass are less than those obtained by the authors in the test-retest. However, the test-retest interval is greater in this study. Consistent relationships are observed between the dimensions of the OPP and three job-related psychosocial indicators: perceived stress, social support and satisfaction. This suggests a good construct validity for the OPP. Although additional validation efforts are recommended, all of the results obtained support the validity and reliability of the French Canadian version of the OPP. This version can be used to examine the importance of organizational aspects in studies on the prevention of chronic disability.
