Study protocol of an effect and process evaluation of the Stamina model; a Structured and Time-effective Approach through Methods for an Inclusive and Active working life

BACKGROUND: The working environment should be a naturally integrated part of business development. Provisions are in place that address the employer’s obligations to investigate, carry out and follow up activities in such a way that ill health and accidents at work are prevented and a satisfactory working environment is achieved. Still, there are organizations that not properly perform systematic work environment management. In order to improve adherence, interventions and models focused on these issues need to be easy to understand and provide rapid feedback of results in order to be implemented. The Stamina model has recently been implemented in Sweden. The model is a participatory organizational systematic model facilitating the work environment, productivity and quality. It is a support model that provides structured and recurrent feedback in the systematic work environment management. The aim of the present paper is to thoroughly describe the Stamina model and the studies that are designed to investigate the effect, to increase the understanding of how and why the model was or was not effective, and to identify factors that facilitate implementation. METHODS: The paper presents a project consisting of two related evaluation parts. Part one is an effect evaluation with an active group applying the Stamina model and a control group. This part investigate effects on proxy outcomes that are relevant for health and productivity. Part two is a process evaluation with a qualitative design. This part will be based on semi-structured interviews with various stakeholders, such as employees, first line managers, project managers, facilitators and representatives from the management group, in the organizations. DISCUSSION: Many interventions found to be effective in research projects fail to translate into meaningful outcomes across multiple contexts. In this project a participatory approach will be adopted, including the possibility to modify the model according to organizational needs and preconditions. Valuable knowledge regarding the design and implementation of the model will be generated in order to develop a model that is suitable and sustainable in organizations.
