Constructing the program impact theory for an evidence-based work rehabilitation program for workers with low back pain.

Abstract

PURPOSE: Several low back pain work rehabilitation programs have been developed and evaluated for their outcomes. Unfortunately, the program impact theory for these programs is not described, and consequently, the exact mechanisms of action by which these programs intend to increase the probability of return to work remain unknown. This lack of knowledge jeopardizes the implementation of effective programs by health professionals and managers. The objective of this paper is to present the results of an exploratory study aimed at building the program impact theory for the PREVICAP work rehabilitation program. METHODS: The program impact theory was develop by conducting: unpublished documents and scientific literature analyses, individual and group discussions with multiple stakeholders and observation of program reality by reviewing the files of workers who completed the program. RESULTS: The PREVICAP program's impact theory was elaborated based on an ecological approach to work rehabilitation. Program goals and objectives were defined for the three dimensions of the model: the worker, the work environment and the interaction between the worker and his work environment. Two program action mechanisms were defined and describe how the program was intended to achieve its expected outcomes. CONCLUSIONS: This study made explicit the PREVICAP program impact theory and can help rehabilitation practitioners to address work disability according to an ecological model.
