Multilevel Analysis of Individual and Contextual Factors as Predictors of Return to Work

Objective: The objective of this study was to examine if individual and contextual levels of work environment factors predict return to work (RTW). Methods: Baseline data from 52 workplaces was linked to a national absence register. Four hundred twenty-eight persons with more than 2 weeks of sickness absence during a 2-year period were identified. Follow up was 1 year to examine three RTW outcomes. Multilevel logistic and Poisson regression models were used. Results: At the individual level, significant associations were found between one psychosocial and four physical factors and RTW within 4 weeks. Two physical factors predicted RTW within 1 year. Two psychosocial and two physical factors significantly prolonged duration of sickness absence. No significant contextual level risk factors were found. Conclusion: At the individual level, both the psychosocial and physical work environment factors are important independent predictors of RTW.
