The goal of this clinical trial is to learn if work-focused cognitive behaviour (WCBT) works to treat patients on sick leave due to non-traumatic long-term stress-related disorders. The main questions it aims to answer are:
* Is WCBT more effective in improving work ability compared to standard care? * Do participants in WCBT have less sick leave days than those in standard care? * Is WCBT more effective in improving health outcomes and function than standard care? * Is WCBT a more cost-effective treatment option than standard care? Researchers will compare WCBT to standad care to see if there are differences in effect.
Participants will participate in:
