Improving the Mental Health of Working Adults in Dutch Small and Medium-Sized Enterprises (SMEs): A Cluster RCT of WHO's Doing What Matters in Times of Stress (DWM)
The goal of this cluster randomized controlled trial is to explore if mental health in Dutch small and medium-sized enterprises (SMEs) can be improved by the World Health Organization's online program Doing What Matters in Times of Stress (DWM). The main questions it aims to answer are: * Does DWM improve the mental health of employees working in Dutch SMEs? * Does DWM improve work-related outcomes in employees working in Dutch SMEs? * How can DWM be implemented at a large scale in Dutch SMEs? Researchers will compare two groups to see if the DWM program is effective. One group will receive the DWM program and Care-as-Usual (group 1), and the other group will receive Care-as-Usual only (group 2). Participants will: * Follow the online DWM program for 5 weeks (only group 1). * Take part in 6 telephone appointments with a facilitator (helper) that provides extra support to complete the program (only group 1). * Complete 3 sets of questionnaires. Each set of questionnaire takes about 15 minutes to be completed (group 1 and group 2).
