Improving psychological detachment from work and well-being with online cognitive-behavioral therapy and mindfulness

INTERVENTION: The intervention will consist of two treatments (cognitive‐behavioral therapy and mindfulness‐based stress reduction) and a waitlist control group. Both interventions will take place online and last for 6 weeks, with two active sessions per week (accompanied by an equal amount of homework). Block randomization (based on demographical data) will be used. Participants will be blinded to the intervention they were allocated to (both interventions will be advertised as occupational stress‐reduction interventions) and control group participants will not be aware that they are part of the control group. Outcomes will be assessed before the intervention (T1), directly after the intervention (T2) and at follow‐up approximately 3 months later (T3).
