Objectives The study aims to identify individual and workplace factors associated with early return to work (RTW)—defined as within 3 months—and factors associated with later RTW—between 3 and 12 months after being sick-listed—in a cohort of newly sick-listed individuals with common mental disorders. Methods In a prospective cohort study, a cross-sectional analysis was performed on baseline measures of patients granted sick leave due to common mental disorders. A total of 533 newly sick-listed individuals fulfilled the inclusion criteria and agreed to participate. A baseline questionnaire was sent by post within 3 weeks of their first day of certified medical sickness; 354 (66 %) responded. Those who were unemployed were excluded, resulting in a study population of 319 individuals. Sick leave was recorded for each individual from the Social Insurance Office during 1 year. Analyses were made with multiple Cox regression analyses. Results Early RTW was associated with lower education, better work ability at baseline, positive expectations of treatment and low perceived interactional justice with the supervisor. RTW after 3 months was associated with a need to reduce demands at work, and turnover intentions. Conclusions Early RTW among sick-listed individuals with common mental disorders seems to be associated with the individual’s need to secure her/his employment situation, whereas later RTW is associated with variables reflecting dissatisfaction with work conditions. No health measures were associated with RTW. The study highlights the importance of considering not only health and functioning, but also workplace conditions and relations at the workplace in implementing RTW interventions.
