[Integration of subjective and objective methods for stress related risks evaluation in the health care sector]

One of the most relevant aspects in the evaluation of occupational stress is concerned with the survey methodology. Several studies adopted subjective and objective methods of evaluation and the debate about the benefits and limitations of both approaches has continued for several years (Frese et al. 1988, Hurrell et al. 1998). To choose an appropriate, specific and focused-on-context evaluation, it is necessary to identify the sources of risk in the investigated area. Then, it is necessary to choose the methods, subjective and objective, more suitable for stress evaluation. In this study we reviewed the psychosocial risk factors that are specific to the health sector and the instruments, objective and subjective, most used in this context. We considered also the methods for the detection of episodes of violence. Finally, we presented the results of a study conducted in the health care sector, which has adopted and compared objective parameters, as potential stressors, and subjective symptoms. The study revealed statistically significant correlations between objective and subjective indicators, suggesting the importance of integrated methods of evaluation.
