Abstract: While many studies of interventions have focused on their content and immediate effects, less research has focused on the processes that may explain these effects. The purpose of this study was to show how process evaluation can be used to interpret the results of an intervention study in four industrial canteens in Denmark. Two canteens acted as intervention groups and two as comparison groups. Effects were measured by surveys before and after interventions, and observations and interviews were conducted to provide an in-depth understanding of processes. Analyses were conducted based on the responses from 118 employees. Results showed, contrary to expectations, improvements in working conditions and well-being in one intervention group and in one comparison group, whereas no improvements were found in the two remaining groups. Data from the process evaluation enabled a meaningful interpretation of these results, raising the possibility of programme failure rather than theory failure, and thereby constituting an example of how process evaluation can shed light over the factors that may influence outcomes in controlled intervention studies.

TL;DR: The findings suggest transformational leadership style may improve perceptions of work-life balance and employee wellbeing.

TL;DR: In this article, the authors explored the main, mediating and moderating role of sense of coherence on stress symptoms and on the association between perceived psychosocial work environment and stress symptoms.

TL;DR: In this paper, the authors used structural equation modeling to explore the impact of employees' direct appraisals of the intervention itself on intervention outcomes and found that participants' appraisal of the activities within an intervention can play an important role in determining the success or failure of a variety of organizational level interventions.

TL;DR: The results supported the overall hypothesis that the work environment influences aspects of smoking behavior and recommendations are made for more intervention studies where changes in work environment are carried out in combination with health promotion interventions.
