Primary outcome
Secondary outcomes
-
Partial RTW is defined as the number of calendar days between the first day of sickness absence due to CMD and the first day of RTW, irrespective of the number of working hours per week.
-
Total number of calendar days of sick leave is calculated for the 1-year follow-up period.
-
CMD symptoms are measured by the Four Dimensional Symptoms Questionnaire (4DSQ), a self-report questionnaire measuring the four dimensions of common psychopathology: distress, depression, anxiety and somatisation. The 4DSQ consists of 50 items (each scored on a 5-point scale) and refers to symptoms during the past week. The 4DSQ has good psychometric properties [18].
-
Burnout symptoms are measured by the Utrechtse Burnout Scale-General Survey (UBOS) [19], which is the Dutch version of the Maslach Burnout Inventory (MBI). The UBOS is a self-report questionnaire which measures three subscales: emotional exhaustion, mental distance, and competence. Higher scores on exhaustion and distance and lower scores on competence indicate burnout. The UBOS is a reliable and valid instrument [20].
Prognostic measures
-
Personal characteristics such as age, gender, level of education, sick leave in the previous year, history of mental disorders, and expectations about full RTW are measured at baseline.
-
Work characteristics such as number of working hours, contract type, type of work, profession and job content are measured at baseline. Job content is measured with the Dutch version of the Job Content Questionnaire (JCQ) [25], a self-report questionnaire which measures the social and psychological characteristics of jobs. The JCQ assesses the following scales: psychological job demands, decision latitude, social support, physical demands and job insecurity.
Additional measures
-
Coping style is measured with the shortened 19-item version of the Utrecht Coping List (UCL) [26], a self-report questionnaire which measures coping behaviour. The 19-item version assesses the following scales: 1) active problem solving, 2) seeking social support, 3) palliative reaction pattern, 4) avoidance behaviour, and 5) expression of emotions.
-
Self-efficacy with regard to RTW is measured by the RTW-SE for workers with mental problems. The RTW-SE is a self-report questionnaire which assesses the self-efficacy in the RTW process. The RTW-SE shows promising reliability, validity and prediction of actual RTW within 3 months [27].
-
Remoralization (perception of recovery) is measured with the 12-item Remoralization Scale (RS-12). The RS-12 is a self-report questionnaire which indicates the level of morale in mental health care and has shown promising reliability and validity [28].
-
Workers’ experiences with the consultations with their OP, and the contact with their supervisor, are measured. For example, the number and content of the consultations, and the topics of the conversations. Satisfaction with the counselling by the OP is measured with an adapted version of the Patient Satisfaction with Occupational Health Professionals Questionnaire (PSOHPQ) [29].
-
Experiences of the supervisor are measured using self-formulated questions. This questionnaire includes topics such as the contact with worker and the OP, previous experience with CMD and sick leave in general, and policy on sick leave and RTW [see Additional file 1].
