Comparative StudyInvestigating risk factors for chronicity: the importance of distinguishing between return-to-work status and self-report measures of disability.
The objective of this study was to examine whether the outcome of psychosocial risk factor analyses varied as a function of whether the outcome variable was return-to-work status or self-reported functional disability. ⋯ Given the important theoretical, clinical, and policy implications of the outcome of risk factor research, more research is needed to further clarify the respective advantages and limitations to using self-reported versus return to work-based measures of disability.
