This paper focuses on the identification and testing of potential psychosocial factors contributing to an integrated multivariate predictive model of occupational low back disability. Psychosocial predictors originate from five traditions of psychosocial research: psychopathological, cognitive, diathesis-stress, human adaptation and organizational(More)
Background: Musculoskeletal pain disorders are the most prevalent, costly, disabling, and commonly researched conditions in the workplace, yet the development of overarching conceptual models of return to work (RTW) in these conditions has been lagging. Method: A critical review of the literature was performed using multiple medical and health search(More)
STUDY DESIGN To establish outcome, 253 workers with subacute and chronic low back conditions were assessed with a comprehensive multimethod biopsychosocial protocol at baseline, 3 days after the initial examination, and 3 months later. OBJECTIVE To validate empirically a biopsychosocial model for prediction of occupational low back disability. SUMMARY(More)
The aim of this research was to determine prognostic indicators of work disability in occupational back pain as reported in the literature, by systematically searching the research literature, assessing the methodological quality of the research, and synthesizing the findings into a concise summary. An article was considered eligible for review if research(More)
Introduction: This paper reports on the predictive validity of a Psychosocial Risk for Occupational Disability Scale in the workers’ compensation environment using a paper and pencil version of a previously validated multimethod instrument on a new, subacute sample of workers with low back pain. Methods: A cohort longitudinal study design with a randomly(More)
Introduction: Screening procedures based on prognostic data are an important prerequisite for prevention of disability due to low-back pain. This paper reviews the research on prognosis to delineate the most pertinent research challenges, and outlines directions for future research to improve the scientific quality and screening accuracy of prognostic(More)
Several systems for measuring pain behaviour have been developed for clinical settings. The present study reports on a real-time system for coding five categories of pain behaviour for low-back pain patients: guarding, touching, sounds, words, and facial expression. Unique features of the system are the use of refined measures of facial expression and(More)
There does not exist an agreed-upon, unifying model of diagnosis and rehabilitation of pain-related occupational disability; rather, multiple, often competing and conflicting models currently operate, both in the literature and in practice. A systematic analysis of the theoretical and empirical literature on pain-related disability was undertaken to(More)
STUDY DESIGN One hundred fifty-nine subacute low back work-injured patients completed a full medical assessment at baseline. A full repeat examination was performed 3 months later, when return-to-work status was determined. OBJECTIVE To determine the prognostic value of a comprehensive medical assessment for the prediction of return-to-work status. (More)
Introduction: Little is known about the formation of expectations of return to work (RTW) from the perspective of injured workers with back injuries. This modified grounded theory study uses a biopsychosocial approach that considers the workers’ complex social circumstances, to unpack the multidimensional construct of expectations of RTW from the injured(More)
