Organizational and Individual Outcomes of Health Promotion Strategies-A Review of Empirical Research.

The main purpose of the paper is to identify the outcomes for employers and employees indicated in research related to workplace health promotion interventions (WHPIs). We investigated what methods are used and what types of organization this type of research is most often carried out in. In addition, the authors attempted to assess to what extent the methods used in the previous research prove the effectiveness of the implemented WHPIs. A systematic review of English-language papers (2000-2020) focused on types of health-promoting interventions in the workplace, and outcomes for employers and employees were conducted using the SCOPUS database (n = 260). As a result, 29 texts qualified for a final qualitative synthesis of the results. The analyses were most frequently conducted in small and medium-sized enterprises (SMEs) based on both quantitative and qualitative methods. In order to draw conclusions, analyses were made by classifying the research presented in the texts according to the type of intervention implemented, classifying the outcomes identified, and indicating the type of evaluation made by the researcher. The analysis showed that most of the outcomes presented refer to changes in the strategy and organizational culture, as well as the behavior of employees. In 18 studies, the indication of outcomes resulted directly from the evaluation outcomes. In other cases, the outcomes were identified by an evaluation of the process or structure of WHPI. The conducted analysis showed significant diversity in terms of the outcomes measured and the research methods used. The quasi-experimental methods, randomly controlled cluster trials, or cross-sectorial studies used in the study to confirm the effectiveness of WHPI were used only in every third study. In these studies, measurements were usually performed twice: at baseline and after intervention. The majority of studies confirmed that WHPIs led to a positive change in the healthy behavior of employees and effected an organizational change, and more rarely led to savings or a reduction in costs resulting from sickness absenteeism, presentism, turnover, etc., and return on investment (ROI). The article shows the need to conduct further research towards the development of guidelines for the evaluation of the effectiveness of implemented programs.
