Measures 
Self-rating
Sick leave data were collected from the Swedish Social Insurance Agency. Self-rating questionnaires (Swedish versions) were completed online via Örebro University’s secure survey system. The baseline assessments were sent out four weeks before intervention, the post intervention assessment was provided immediately after, and the follow-up 6-months after the intervention. Non-responders were reminded via e-mail and a maximum of two phone calls from a research coordinator. At the post intervention and 6-months follow-up, all participants received a movie ticket for completed questionnaires. Demographic information about age, sex, education level, social and occupational status were assessed at baseline. Program participation was assessed by self-report at post intervention. For supervisors, individuals with missing information on program participation were contacted through email and/or telephone calls.The following outcomes were evaluated for the individual employees.
