Objective: To investigate the effectiveness of a combined social and physical environmental intervention as well as the effectiveness of both separate interventions.
Methods: In a 2 × 2 factorial design, 412 office employees were allocated to the combined social and physical environmental intervention, to the social environmental intervention only, to the physical environmental intervention only, or were part of the control group. Data on presenteeism, absenteeism, work performance, and work engagement were obtained with questionnaires at baseline, 6, and 12 months. Multilevel analyses were performed.
Results: The combined intervention showed a decrease in contextual performance and dedication. The social environmental intervention showed an improvement in task performance. The physical environmental intervention revealed an improvement in absorption.
Conclusion: Although the study showed some promising results, it is not recommended to implement the current interventions.
