prediction of Occupational Disability from psychological and neuropsychological evidence in forensic context
International Journal of Law and Psychiatry, 2016Co-Authors: Izabela Z Schultz, Ada K Law, Leanna C CruikshankAbstract:Abstract Within the fields of psychiatry, psychology, and neuropsychology, medical examiners are often tasked with providing an opinion about an injured individual's health prognosis and likelihood of returning to work. Traditionally, examiners have conducted such assessments by employing clinical intuition, expert knowledge, and judgment. More recently, however, an accumulation of research on factors predictive of Disability has allowed examiners to provide prognostications using specific empirically supported evidence. This paper integrates current evidence for four common clinical issues encountered in forensic assessments—musculoskeletal pain, depression, Posttraumatic Stress Disorder, and traumatic brain injury. It discusses an evidence-informed, cross-diagnostic and multifactorial model of predicting Disability that is emerging from the literature synthesis, along with recommendations for best forensic assessment practice.

models of diagnosis and rehabilitation in musculoskeletal pain related Occupational Disability
Journal of Occupational Rehabilitation, 2008Co-Authors: Izabela Z Schultz, Joan Crook, Peter W. Joy, Kerri FraserAbstract:Musculoskeletal, pain-related Occupational injuries are among the most common and disabling impairments in the working population and pose a formidable health care problem for industry. Annually, 2% of the national work force incurs industrialrelated back injuries, with approximately 1.4% of these resulting in a period of work absence (1). Despite the good prognosis for most episodes, musculoskeletal injuries consume considerable resources in medical care, absence from work, productivity losses and compensation benefits. Spitzer (1) found that about three-quarters of workinjured employees return to work in two to three weeks. Only about 7% had not returned by six months; however, these few accounted for about 75% of costs to the compensation system in lost hours, indemnities, and utilization of health services.

models of return to work for musculoskeletal disorders
Journal of Occupational Rehabilitation, 2007Co-Authors: Izabela Z Schultz, Robert J Gatchel, Anna W Stowell, Michael FeuersteinAbstract: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 engines in order to provide an evaluation of the evolution and the state of the art of health and Disability models with a focus on specific models of RTW. Results: The main tenets, implications for diagnosis, treatment, and Disability compensation, are the key perspectives analyzed for the following specific models of RTW: biomedical, psychosocial, forensic, ecological/case management, biopsychosocial, and two more recent models developed by the Institute of Medicine and the World Health Organization, respectively. Conclusions: Future development of models that are truly transdisciplinary, and address temporal and multidimensional aspects of Occupational Disability, remains a goal.

predicting return to work after low back injury using the psychosocial risk for Occupational Disability instrument a validation study
Journal of Occupational Rehabilitation, 2005Co-Authors: Izabela Z Schultz, Joan Crook, Jonathan Berkowitz, Ruth Milner, G R MelocheAbstract: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 selected cohort off work for 4–6 weeks was applied. The questionnaire was completed by 111 eligible workers at 4–6 weeks following injury. Return to work status data at three months was obtained from 100 workers. Sixty-four workers had returned to work (RTW) and 36 had not (NRTW). Results: Stepwise backward elimination resulted in a model with these predictors: Expectations of Recovery, SF-36 Vitality, SF-36 Mental Health, and Waddell Symptoms. The correct classification of RTW/NRTW was 79%, with sensitivity (NRTW) of 61% and specificity (RTW) of 89%. The area under the ROC curve was 84%. Conclusions. New evidence for predictive validity for the Psychosocial Risk-for-Disability Instrument was provided. Implications: The instrument can be useful and practical for prediction of return to work outcomes in the subacute stage after low back injury in the workers’ compensation context.

biopsychosocial multivariate predictive model of Occupational low back Disability
Spine, 2002Co-Authors: Izabela Z Schultz, Joan Crook, Jonathan Berkowitz, Ruth Milner, G R Meloche, Oonagh A Zuberbier, Wendy MelocheAbstract:Low back injury rates have stabilized (Murphy & Volinn, 1999), but the growing economic burden of low back Occupational Disability (Volinn, Van Koevering & Loeser, 1991) has fuelled an extensive international research effort to identify risk factors for this condition. Over 1000 research and review papers were published in the last decade (Crook et al., 2002). Several empirically-based prediction models have been constructed (Feuerstein & Thebarge, 1991; Frymoyer, 1992; Gatchel, Polatin K Halpern et al., 2001; Hazard et al., 1996; Linton&Hallden, 1997) to parallel theoretical models of Occupational musculoskeletal Disability (Schultzet al., 2000). At present, however, a limited convergence remains among different empirically-derived models and between empirical and theoretical models.

determinants of Occupational Disability following a low back injury a critical review of the literature
Journal of Occupational Rehabilitation, 2002Co-Authors: Joan Crook, Izabela Z Schultz, Ruth Milner, Bernadette StringerAbstract: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 participants had an injury of the back, the article was based on original research, published in English, and involved a cohort with back pain less than 6 months post injury with at least one follow up assessment. Each article was independently reviewed by two “blinded” reviewers using 19 appraisal criteria for methodological quality of prognostic studies. Nineteen studies met the methodological standard to be included. Time since onset, demographic factors, functional Disability, psychological distress, pain reports, previous episodes, and work environment were identified as important prognostic factors. Most studies compartmentalized the factors they considered. What is needed is a comprehensive multivariate biopsychosocial job-related model of work Disability.

Models of Diagnosis and Rehabilitation in Musculoskeletal Pain-Related Occupational Disability
Journal of Occupational Rehabilitation, 2000Co-Authors: Izabela Z Schultz, Joan Crook, Kerri Fraser, Peter W. JoyAbstract: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 identify current conceptual models of diagnosis and rehabilitation. Five relevant conceptual models were chosen for review: the biomedical model, the psychiatric model, the insurance model, the labor relations model, and the biopsychosocial model. The analysis focused on the key theoretical tenets of each model, underlying values, implications for clinical practice, and management by compensation and health care systems.

the relation between perceived injustice and symptom severity in individuals with major depression a cross lagged panel study
Journal of Affective Disorders, 2020Co-Authors: Michael J L Sullivan, Keiko Yamada, Yasuhiko Kubota, Heather Adams, Tamra Ellis, Pascal ThibaultAbstract:Abstract Background: Perceived injustice has been associated with problematic recovery outcomes in individuals with debilitating health conditions. However, the relation between perceived injustice and recovery outcomes has not been previously examined in individuals with debilitating mental health conditions. The present study examined the relation between perceived injustice and symptom severity in individuals undergoing treatment for Major Depressive Disorder (MDD). Methods: The study sample consisted of 253 work-disabled individuals with MDD who were referred to an Occupational rehabilitation service. Participants completed measures of depressive symptom severity, perceived injustice, catastrophic thinking, pain and Occupational Disability at three time-points (pre-, mid- and post-treatment) during a 10-week behavioural activation intervention. Results: Regression analysis on baseline data revealed that perceived injustice contributed significant variance to the prediction of depressive symptom severity, beyond the variance accounted for by time since diagnosis, pain severity and catastrophic thinking. Prospective analyses revealed that early treatment reductions in perceived injustice predicted late treatment reductions in depressive symptom severity. Limitations: The study sample consisted of work-disabled individuals with MDD who had been referred to an Occupational rehabilitation service. This selection bias has implications for the generalizability of findings. Conclusion: The findings suggest that perceived injustice is a determinant of symptom severity in individuals with MDD. The inclusion of techniques designed to reduce perceived injustice might augment positive treatment outcomes for individuals receiving treatment for MDD.

sensitivity to movement evoked pain and multi site pain are associated with work Disability following whiplash injury a cross sectional study
Journal of Occupational Rehabilitation, 2017Co-Authors: Tsipora Mankovskyarnold, Timothy H Wideman, Pascal Thibault, Christian Lariviere, Pierre Rainville, Michael J L SullivanAbstract:Objectives Previous research has shown that sensitivity to movement-evoked pain is associated with higher scores on self-report measures of Disability in individuals who have sustained whiplash injuries. However, it remains unclear whether sensitivity to movement-evoked pain is associated with work-Disability. The aim of the present study was to examine the relation between sensitivity to movement-evoked pain and Occupational status in individuals receiving treatment for whiplash injury. Methods A sample of 105 individuals with whiplash injuries participated in a testing session where different measures of pain (i.e. spontaneous pain, multi-site pain, sensitivity to movement-evoked pain) were collected during the performance of a simulated Occupational lifting task. Results Hierarchical logistic regression analysis revealed that the measures of multisite pain and sensitivity to movement-evoked pain made significant independent contributions to the prediction of work-Disability. Discussion The findings suggest that including measures of multisite pain and sensitivity to movement evoked pain in assessment protocols has the potential to increase the value of pain assessments for the prediction of Occupational Disability associated with whiplash injury. Clinical and theoretical implications of the findings are addressed.

the relation between catastrophizing and Occupational Disability in individuals with major depression concurrent and prospective associations
Journal of Occupational Rehabilitation, 2017Co-Authors: Heather Adams, Pascal Thibault, Tamra Ellis, Emily Moore, Michael J L SullivanAbstract:Background Catastrophic thinking has been associated with Occupational Disability in individuals with debilitating pain conditions. The relation between catastrophic thinking and Occupational Disability has not been previously examined in individuals with debilitating mental health conditions. The present study examined the relation between catastrophic thinking and Occupational Disability in individuals with major depression. Methods The study sample consisted of 80 work-disabled individuals with major depressive disorder (MDD) who were referred to an Occupational rehabilitation service. Participants completed measures of depressive symptom severity, catastrophic thinking and Occupational Disability at admission and termination of a rehabilitation intervention. Return-to-work outcomes were assessed 1 month following the termination of the rehabilitation intervention. Results Cross-sectional analyses of admission data revealed that catastrophic thinking contributed significant variance to the prediction of self-reported Occupational Disability, beyond the variance accounted for by depressive symptom severity. Prospective analyses revealed that reductions in catastrophic thinking predicted successful return to work following the rehabilitation intervention, beyond the variance accounted for by reductions in depressive symptom severity. Conclusions The findings suggest that catastrophic thinking is a determinant of Occupational Disability in individuals with major depressive disorder. The findings further suggest that interventions designed to reduce catastrophic thinking might promote Occupational re-integration in individuals with debilitating mental health conditions.

further validation of a measure of injury related injustice perceptions to identify risk for Occupational Disability a prospective study of individuals with whiplash injury
Journal of Occupational Rehabilitation, 2013Co-Authors: Whitney Scott, Zina Trost, Maria Milioto, Michael J L SullivanAbstract:Purpose Emerging evidence suggests that perceptions of injustice negatively impact return to work following whiplash injury. The Injustice Experiences Questionnaire (IEQ) is a recently developed measurement tool that may be used to assess injury-related perceptions of injustice following injury. To date, although research has supported the predictive validity of the IEQ, a clinical cut off for interpreting this measure has not been established. Increased support for the validity and clinical interpretation of the IEQ represents a first step towards identifying patients that might benefit from targeted intervention to mitigate the impact of perceived injustice. Methods The IEQ was completed by 103 whiplash-injured patients upon commencement and completion of a standardized multidisciplinary rehabilitation program. One year later, individuals reported on their employment activity, pain severity, and use of narcotics. A receiver operating characteristic (ROC) curve analysis was conducted to identify the post-treatment IEQ score that was optimally associated with unemployment status at the follow-up. Secondary ROC curve analyses examined IEQ scores best associated with high pain severity and narcotic use 1 year following treatment. Results Results indicated that IEQ scores significantly discriminated individuals who returned and did not return to work at the follow-up. An IEQ score of 19 optimally identified participants in terms of follow-up employment status. IEQ scores at the end of treatment also discriminated individuals with high and low pain severity ratings and narcotic use status at the follow-up. Post-treatment IEQ scores of 18 and 20 optimally identified participants who had high pain severity ratings and who were using narcotics at the follow-up, respectively. Conclusions These results further support the validity of the IEQ and provide a guideline for its clinical interpretation in patients with persistent pain and Disability following musculoskeletal injury. IEQ scores above the identified cut off may represent a barrier to work return and may warrant targeted intervention.

pain chronicity and Disability
2013Co-Authors: Michael J L Sullivan, Marc O Martel, Zina TrostAbstract:Pain is a central element of the experience of musculoskeletal injury. In a small but significant proportion of individuals who sustain musculoskeletal injury, pain symptoms will persist indefinitely. In recent years, efforts have been made to identify factors that might predispose individuals to the development of chronic pain. This chapter briefly discusses research that has addressed the neurophysiological and psychological factors that might play a role in the transition from acute to chronic pain. The role of chronic pain in prolonged Occupational Disability is explored and treatment implications are addressed.
