**5. Conclusions and Practice Implications**

This study of vocational rehabilitation in men and women on long-term sick leave due to mental illness and/or chronic pain showed that multidisciplinary team assessments and individually adapted rehabilitation interventions increased RTW and employability. Sole ACT intervention increased employability.

The study implies that it is possible to increase RTW among people on long-term sick leave due to mental illness and/or chronic pain with a multidisciplinary rehabilitation intervention. Multidisciplinary team rehabilitation and sole ACT also seem to be useful for increasing employability and gradually moving people in a stepwise positive direction, through the welfare system, and eventually toward RTW.
