Intervention studies in the health care work environment : Lessons learned

TLDR: Five different methods of integration are proposed: a qualitative approach as a foundation for the design of a quantitative study, qualitative studies to gain deeper insight and better analyses of the results from a qualitative study, quantitative research to study frequencies and distributions of phenomena discovered by qualitative approaches, parallel and integrated use of qualitative and quantitative approaches, and quantifying qualitative data.

Abstract: The old controversy between qualitative and quantitative approaches to the study of workplace stressors and workers ́ health may be bypassed by looking at them as complementary to each other. Especially, intervention research would profit from the integrated use of both approaches when it comes to validity and reliability of the data. This applies to assessment of both the work and health related problems as well as the effects of the intervention. Also quite practical issues must be considered, such as the question of status for the two approaches within the research group, the possibility to integrate the two methods, not only conduct them in separate and parallel processes, and the sequencing of the approaches. Five different methods of integration are proposed: 1) a qualitative approach as a foundation for the design of a quantitative study, 2) qualitative studies to gain deeper insight and better analyses of the results from a quantitative study, 3) quantitative research to study frequencies and distributions of phenomena discovered by qualitative approaches, 4) parallel and integrated use of qualitative and quantitative approaches, and 5) quantifying qualitative data.
