Countries of recruitment Netherlands
Disease/condition/study domain Sick leave due to common mental disorders
Participants - inclusion criteria 1. A common mental disorder, i.e. anxiety, depression, burnout or emotional distress, is the primary reason for sick leave at the time of inclusion. Physical problems may be present, but should not cause absenteeism.
2. Dutch speaking
3. Counseled by an OP that takes part in the study
Participants - exclusion criteria 1. Acute crisis or suicidality
2. Sick leave duration of less than 4 weeks, as a quick recovery of part of this group may dilute the statistical power of the study
3. Sick leave duration of more than 8 weeks, as the study aims to prevent long term sick leave

Target number of participants 232
Interventions OPs in the experimental condition are trained in the Dutch guideline 'management of workers with common mental health problems by occupational physicians'. OPs will be divided into groups of 6 - 10 OPs, and will gather for monthly meetings of approximately 1 hour, over 1 year. Using action research and focus group discussions it will be investigated which barriers OPs encounter in using the guideline. Subsequently, barriers will be explored and possible solutions will be discussed by means of a 'plan, do, check, act' cycle.

OPs from the control group provide care as usual.

The total duration of follow up will be 12 months.
Primary outcome measure(s) Time to full return to work, defined as the number of days between the first day of sickness absence and the first day of full return to work
Secondary outcome measure(s) 1. Partial return to work
2. Total days of sick leave at 12 months
3. Patient satisfaction, assessed by a short questionnaire developed for this study
4. Symptoms, measured using the 4DSQ (Terluin 2002)

Outcomes will be assessed at baseline, 3, 6 and 12 months.
