Abstract
This pragmatic randomized controlled trial examined the effectiveness of reviga, a self-guided digital intervention based on cognitive behavioral therapy, in reducing work-related stress symptoms. A total of 290 adults experiencing significant stress and burnout were assigned to the intervention group (reviga + treatment as usual [TAU]; n = 147) or the control group (TAU only; n = 143). Intent-to-treat analyses showed that 3 months post-randomization, participants in the intervention group experienced significant positive effects on the primary outcome, perceived stress (Cohen's d = 0.36), as well as on the secondary outcomes anxiety (d = 0.28), burnout (d = 0.31), occupational and social functioning (d = 0.31) and health-related quality of life (d = 0.35) compared to TAU. No effect was found for absenteeism quantified as the number of sick days. Effect sizes increased at 6 month follow-up. This study demonstrates that reviga represents a promising and scalable tool for workplace mental health support.
