The intervention and control groups are compared in terms of well-being, work-related satisfaction, and return to the workplace.

Improving the diagnostic procedure for injured patients: a randomised controlled trial
1. A significant difference in psychological and work-related outcome is expected between groups (OptiFAB and FABpur). Specifically, it is assumed that the group with the psychological and/or work-related intervention will have better outcomes in terms of psychological functioning (well-being) and a faster reintegration into the workplace.
2. A difference in term of a better triage is expected between groups (FABplus and FABpur). As above, it is assumed that the group with a GAS training and a manual will have better and faster triage process.
