Prognostic Factors for the Work Participation of Sick-Listed Unemployed and Temporary Agency Workers with Psychological Problems

Introduction Among the working population, unemployed and temporary agency workers are a particularly vulnerable group, at risk for sickness absence due to psychological problems. Knowledge of prognostic factors for work participation could help identify sick-listed workers with a high-risk for work disability and provide input for sickness absence counseling. The purpose of this study was to identify prognostic factors for the work participation of medium- and long-term sick-listed unemployed and temporary agency workers with psychological problems. Methods A cohort of 932 sick-listed unemployed and temporary agency workers with psychological problems was followed for one and a half years. Data collection was conducted at three time-frames: 10 months, 18 months and 27 months after reporting sick. Univariate and multiple logistic regression analyses were performed. Results Perceived health, full return-to-work (RTW) expectations, age and work status at 18 months were strong prognostic factors for work participation at subsequent time-frames in the univariate analyses. Multiple logistic regression revealed that full RTW expectation was a prognostic factor for future work participation in both the medium- and long-term, whereas moderate-to-good perceived health was a prognostic factor for work participation in the medium-term. Being under 45 years of age and having a positive work status at 18 months were prognostic factors for work participation in the long-term. Conclusions Workers' self-appraisal of health, age and work status were strong prognostic factors for the future work participation of sick-listed unemployed and temporary agency workers with psychological problems. These findings could help occupational and insurance physicians identify high-risk sick-listed workers for sickness absence counseling
