A Sensibility Assessment of the Job Demands and Accommodation Planning Tool (JDAPT): A Tool to Help Workers with an Episodic Disability Plan Workplace Support.

Purpose Sensibility refers to a tool's comprehensiveness, understandability, relevance, feasibility, and length. It is used in the early development phase to begin assessing a new tool or intervention. This study examined the sensibility of the job demands and accommodation planning tool (JDAPT). The JDAPT identifies job demands related to physical, cognitive, interpersonal, and working conditions to better target strategies for workplace supports and accommodations aimed at assisting individuals with chronic health conditions. Methods Workers with a chronic health condition and workplace representatives were recruited from health charities, workplaces, and newsletters using convenience sampling. Cognitive interviews assessed the JDAPT's sensibility. A 70% endorsement rate was the minimum level of acceptability for sensibility concepts. A short screening tool also was administered, and answers compared to the complete JDAPT. Results Participants were 46 workers and 23 organizational representatives (n = 69). Endorsements highly exceeded the 70% cut-off for understandability, relevance, and length. Congruence between screening questions and the complete JDAPT suggested both workers and organizational representatives overlooked job demands when completing the screener. Participants provided additional examples and three new items to improve comprehensiveness. The JDAPT was rated highly relevant and useful, although not always easy to complete for someone with an episodic condition. Conclusions This study highlights the need for tools that facilitate accommodations for workers with episodic disabilities and provides early evidence for the sensibility of the JDAPT.

Disclosure, Privacy and Workplace Accommodation of Episodic Disabilities: Organizational Perspectives on Disability Communication-Support Processes to Sustain Employment.

Purpose Employers increasingly are asked to accommodate workers living with physical and mental health conditions that cause episodic disability, where periods of wellness are punctuated by intermittent and often unpredictable activity limitations (e.g., depression, anxiety, arthritis, colitis). Episodic disabilities may be challenging for workplaces which must comply with legislation protecting the privacy of health information while believing they would benefit from personal health details to meet a worker's accommodation needs. This research aimed to understand organizational perspectives on disability communication-support processes. Methods Twenty-seven participants from diverse employment sectors and who had responsibilities for supporting workers living with episodic disabilities (e.g., supervisors, disability managers, union representatives, occupational health representatives, labour lawyers) were interviewed. Five participants also had lived experience of a physical or mental health episodic disability. Participants were recruited through organizational associations, community networks and advertising. Semi-structured interviews and qualitative content analysis framed data collection and analyses, and mapped communication-support processes. Results Seven themes underpinned communication-support process: (1) similarities and differences among physical and mental health episodic disabilities; (2) cultures of workplace support, including contrasting medical and biopsychosocial perspectives; (3) misgivings about others and their role in communication-support processes; (4) that subjective perceptions matter; (5) the inherent complexity of the response process; (6) challenges arising when a worker denies a disability; and (7) casting disability as a performance problem. Conclusions This study identifies a conceptual framework and areas where workplace disability support processes could be enhanced to improve inclusion and the sustainability of employment among workers living with episodic disabilities.

How Do Organizational Policies and Practices Affect Return to Work and Work Role Functioning Following a Musculoskeletal Injury?

Purpose Organizational-level policies and practices that promote safety leadership and practices, disability management and ergonomic policies and practices are considered key contextual determinants of return to work. Our objective was to examine the role of worker-reported organizational policies and practices (OPPs) in return to work (RTW) and work role functioning (WRF) and the mediating role of pain self-efficacy and work accommodation. Methods A worker cohort (n = 577) in Ontario, Canada was followed at 1, 6 and 12 months post injury. Both RTW (yes/no) and WRF (WLQ-16) status (3 levels) were measured. OPPs were measured (high vs. low) at 1 month post-injury. Pain self-efficacy (PSE) and work accommodation (WA) were included in mediation analyses. Results OPPs predicted RTW at 6 months (adjusted OR 1.77; 95 % CI 1.07-2.93) and 12 months (adjusted OR 2.07; 95 % CI 1.18-3.62). OPPs predicted WRF at 6 months, but only the transition from working with limitations to working without limitations (adjusted OR 3.21; 95 % CI 1.92-5.39). At 12 months, OPPs predicted both the transition from not working to working with and without limitations and from not working or working with limitations to working without limitations (adjusted OR 2.13; 95 % CI 1.37-3.30). Offers of WA mediated the relationship between OPPs and both RTW and WRF at 6 months follow-up. PSE mediated the relationship between OPPs and RTW and WRF at 6 months. At 12 months neither mediated the relationship. Conclusions The findings support worker-reported OPPs as key determinants of both RTW and WRF. These results point to the importance of WA and PSE in both RTW and WRF at 6 months.

The Added Value of Collecting Information on Pain Experience When Predicting Time on Benefits for Injured Workers with Back Pain.

Objectives Some injured workers with work-related, compensated back pain experience a troubling course in return to work. A prediction tool was developed in an earlier study, using administrative data only. This study explored the added value of worker reported data in identifying those workers with back pain at higher risk of being on benefits for a longer period of time. Methods This was a cohort study of workers with compensated back pain in 2005 in Ontario. Workplace Safety and Insurance Board (WSIB) data was used. As well, we examined the added value of patient-reported prognostic factors obtained from a prospective cohort study. Improvement of model fit was determined by comparing area under the curve (AUC) statistics. The outcome measure was time on benefits during a first workers' compensation claim for back pain. Follow-up was 2 years. Results Among 1442 workers with WSIB data still on full benefits at 4 weeks, 113 were also part of the prospective cohort study. Model fit of an established rule in the smaller dataset of 113 workers was comparable to the fit previously established in the larger dataset. Adding worker rating of pain at baseline improved the rule substantially (AUC = 0.80, 95 % CI 0.68, 0.91 compared to benefit status at 180 days, AUC = 0.88, 95 % CI 0.74, 1.00 compared to benefits status at 360 days). Conclusion Although data routinely collected by workers' compensation boards show some ability to predict prolonged time on benefits, adding information on experienced pain reported by the worker improves the predictive ability of the model from 'fairly good' to 'good'. In this study, a combination of prognostic factors, reported by multiple stakeholders, including the worker, could identify those at high risk of extended duration on disability benefits and in potentially in need of additional support at the individual level.

Course of Depressive Symptoms Following a Workplace Injury: A 12-Month Follow-Up Update.

Introduction To estimate the prevalence, incidence and course of depressive symptoms, their relationship with return-to-work, and prevalence of depression diagnosis/treatment 12 months following a lost-time workplace musculoskeletal injury. Methods In a prospective cohort study, 332 workers' compensation claimants with a back or upper extremity musculoskeletal disorder completed interviews at 1, 6 and 12 months post-injury. Participants self-reported they had not received a depression diagnosis 1 year pre-injury. Cutoff of 16 on the CES-D defined a high level of depressive symptoms. Self-reported data on depression diagnosis and treatment and work status since injury were collected. Results Cumulative incidence of high depressive symptom levels over 12 months was 50.3 % (95 % CI 44.9-55.7 %). At 12 months, 24.7 % (95 % CI 20.1-29.3 %) of workers exhibited high levels. Over 12 months, 49.7 % (95 % CI 44.3-55.1 %) had low levels at all 3 interviews, 14.5 % (95 % CI 10.7-18.2 %) had persistently high levels, and 25.6 % (95 % CI 20.9-30.3 %) demonstrated improvements. Among workers with low baseline levels, incidence of high levels at 12 months was 6.0 % (95 % CI 2.7-9.3 %). For workers with high baseline levels, 36.1 % (95 % CI 27.9-44.3 %) exhibited persistent high symptoms at 6 and 12 months, while 38.4 % (95 % CI 30.1-46.6 %) experienced low levels at 6 and 12 months. Problematic RTW outcomes were common among workers with a poor depressive symptom course. Among workers with persistent high symptoms, 18.8 % (95 % CI 7.7-29.8 %) self-reported receiving a depression diagnosis by 12 months and 29.2 % (95 % CI 16.3-42.0 %) were receiving treatment at 12 months. Conclusions Depressive symptoms are common in the first year following a lost-time musculoskeletal injury and a poor depressive symptom course is associated with problematic RTW outcomes 12 months post-injury. While symptoms appear to improve over time, the first 6 months appear to be important in establishing future symptom levels and may represent a window of opportunity for early screening.

Workplace interventions to prevent work disability in workers on sick leave.

BACKGROUND: Work disability has serious consequences for individuals as well as society. It is possible to facilitate resumption of work by reducing barriers to return to work (RTW) and promoting collaboration with key stakeholders. This review was first published in 2009 and has now been updated to include studies published up to February 2015. OBJECTIVES: To determine the effectiveness of workplace interventions in preventing work disability among sick-listed workers, when compared to usual care or clinical interventions. SEARCH METHODS: We searched the Cochrane Work Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and PsycINFO databases on 2 February 2015. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of workplace interventions that aimed to improve RTW for disabled workers. We only included studies where RTW or conversely sickness absence was reported as a continuous outcome. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed risk of bias of the studies. We performed meta-analysis where possible, and we assessed the quality of evidence according to GRADE criteria. We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included 14 RCTs with 1897 workers. Eight studies included workers with musculoskeletal disorders, five workers with mental health problems, and one workers with cancer. We judged six studies to have low risk of bias for the outcome sickness absence.Workplace interventions significantly improved time until first RTW compared to usual care, moderate-quality evidence (hazard ratio (HR) 1.55, 95% confidence interval (CI) 1.20 to 2.01). Workplace interventions did not considerably reduce time to lasting RTW compared to usual care, very low-quality evidence (HR 1.07, 95% CI 0.72 to 1.57). The effect on cumulative duration of sickness absence showed a mean difference of -33.33 (95% CI -49.54 to -17.12), favouring the workplace intervention, high-quality evidence. One study assessed recurrences of sick leave, and favoured usual care, moderate-quality evidence (HR 0.42, 95% CI 0.21 to 0.82). Overall, the effectiveness of workplace interventions on work disability showed varying results.In subgroup analyses, we found that workplace interventions reduced time to first and lasting RTW among workers with musculoskeletal disorders more than usual care (HR 1.44, 95% CI 1.15 to 1.82 and HR 1.77, 95% CI 1.37 to 2.29, respectively; both moderate-quality evidence). In studies of workers with musculoskeletal disorders, pain also improved (standardised mean difference (SMD) -0.26, 95% CI -0.47 to -0.06), as well as functional status (SMD -0.33, 95% CI -0.58 to -0.08). In studies of workers with mental health problems, there was a significant improvement in time until first RTW (HR 2.64, 95% CI 1.41 to 4.95), but no considerable reduction in lasting RTW (HR 0.79, 95% CI 0.54 to 1.17). One study of workers with cancer did not find a considerable reduction in lasting RTW (HR 0.88, 95% CI 0.53 to 1.47).In another subgroup analysis, we did not find evidence that offering a workplace intervention in combination with a cognitive behavioural intervention (HR 1.93, 95% CI 1.27 to 2.93) is considerably more effective than offering a workplace intervention alone (HR 1.35, 95% CI 1.01 to 1.82, test for subgroup differences P = 0.17).Workplace interventions did not considerably reduce time until first RTW compared with a clinical intervention in workers with mental health problems in one study (HR 2.65, 95% CI 1.42 to 4.95, very low-quality evidence). AUTHORS' CONCLUSIONS: We found moderate-quality evidence that workplace interventions reduce time to first RTW, high-quality evidence that workplace interventions reduce cumulative duration of sickness absence, very low-quality evidence that workplace interventions reduce time to lasting RTW, and moderate-quality evidence that workplace interventions increase recurrences of sick leave. Overall, the effectiveness of workplace interventions on work disability showed varying results. Workplace interventions reduce time to RTW and improve pain and functional status in workers with musculoskeletal disorders. We found no evidence of a considerable effect of workplace interventions on time to RTW in workers with mental health problems or cancer.We found moderate-quality evidence to support workplace interventions for workers with musculoskeletal disorders. The quality of the evidence on the effectiveness of workplace interventions for workers with mental health problems and cancer is low, and results do not show an effect of workplace interventions for these workers. Future research should expand the range of health conditions evaluated with high-quality studies.

The Predictive Validity of the Return-to-Work Self-Efficacy Scale for Return-to-Work Outcomes in Claimants with Musculoskeletal Disorders.

PURPOSE: To examine the predictive validity of the Return-to-Work Self-Efficacy (RTWSE) Scale in terms of the scale's baseline absolute values and of changes in self-efficacy scores, with the outcome of return-to-work (RTW) status in a sample of injured workers with upper extremity and back musculoskeletal disorders. METHODS: RTWSE was measured with a 10-item scale assessing Overall RTWSE and three self-efficacy subdomains: (1) ability to cope with pain, (2) ability to obtain help from supervisor and (3) ability to obtain help from co-workers. Outcome measures included RTW status (yes/no) measured at 6- and 12-month follow-up. RTWSE improvement was defined as an increase in self-efficacy scores between baseline and 6-month follow-up time points. Logistic regression analyses were performed with RTW status as the dependent variable and adjusted for age, gender, educational level, personal income, pain site, pain severity, functional status, and depressive symptoms, and for baseline RTWSE scores in the improvement score analyses. RESULTS: A total of 632 claimants completed the baseline telephone interview 1 month post-injury; 446 subjects completed the 6-month interview (71 %) and 383 subjects completed the 12-month interview (61 %). The baseline Pain RTWSE scores were found to be useful to predict RTW status 6 months post-injury, with a trend for baseline Overall RTWSE. Improvements over time in Overall RTWSE and in Co-worker RTWSE were found to be useful to predict 12-month RTW status, with trends for improvements in Supervisor RTWSE and Pain RTWSE. CONCLUSION: The study found evidence supporting the predictive validity of the RTWSE scale within 12 months after injury. The RTWSE scale may be a potentially valuable scale in research and in managing work disabled claimants with musculoskeletal disorders.

Pain-related work interference is a key factor in a worker/workplace model of work absence duration due to musculoskeletal conditions in Canadian nurses.

OBJECTIVE: To examine the role of pain experiences in relation to work absence, within the context of other worker health factors and workplace factors among Canadian nurses with work-related musculoskeletal (MSK) injury. METHODS: Structural equation modeling was used on a sample of 941 employed, female, direct care nurses with at least one day of work absence due to a work-related MSK injury, from the cross-sectional 2005 National Survey of the Work and Health of Nurses. RESULTS: The final model suggests that pain severity and pain-related work interference mediate the impact of the following worker health and workplace factors on work absence duration: depression, back problems, age, unionization, workplace physical demands and low job control. The model accounted for 14 % of the variance in work absence duration and 46.6 % of the variance in pain-related work interference. CONCLUSIONS: Our findings support a key role for pain severity and pain-related work interference in mediating the effects of workplace factors and worker health factors on work absence duration. Future interventions should explore reducing pain-related work interference through addressing workplace issues, such as providing modified work, reducing physical demands, and increasing job control.

When health care workers experience mental ill health: institutional practices of silence.

Based on findings from an institutional ethnography in a large mental health organization, we explore how institutional forces shape the experiences of health care workers with mental health issues. We interviewed 20 employees about their personal experiences with mental health issues and work and 12 workplace stakeholders about their interactions with workers who had mental health issues. We also reviewed organizational texts related to health, illness, and productivity. In analyzing transcripts and texts, silence emerged as a core underlying process characterizing individual and organizational responses to employees with mental health issues. Silence was an active practice that took many forms; it was pervasive, complex, and at times, paradoxical. It served many functions for workers and the organization. We discuss the theoretical and practical implications of the findings for workers with mental health issues.

Workplace-based work disability prevention interventions for workers with common mental health conditions: a review of the literature.

INTRODUCTION: To summarize evidence on workplace-based work disability prevention (WDP) interventions in workers with common mental health conditions (CMHCs). Primary outcomes of interest were work absence duration and work functioning; secondary outcomes were quality of life, and economic costs. METHODS: We conducted a systematic literature search in 5 electronic databases (MEDLINE, EMBASE, CINAHL, PsychINFO, Web of Science) for studies published from 2007 to 2009. Two reviewers screened for studies: (1) Targeting workers with CMHCs absent from, or struggling at, work; (2) evaluating workplace-based WDP interventions; (3) assessing our primary outcome(s); and (4) with controlled trials. Quality assessment (using 29 criteria) was performed by two reviewers. RESULTS: Our search yielded 671 abstracts: 8 eligible studies and of sufficient quality. We identified three main intervention elements: (a) Facilitation of access to clinical treatment; (b) Workplace-based high-intensity psychological intervention; and (c) Facilitation of navigation through the disability management system. Moderate evidence was found that facilitation of treatment improved work functioning, quality of life and economic outcomes, with limited evidence for work absence duration. Moderate evidence was found that psychological interventions, primarily cognitive-behavioral therapy, improved work functioning, quality of life, and economic outcomes. Moderate evidence indicated that facilitation of navigation through the disability management system improved work absence duration. CONCLUSIONS: Workplace-based interventions could improve work disability outcomes for workers with CMHCs. Facilitation of access to clinical treatment, and workplace-based high-intensity psychological intervention were most effective in improving work functioning and quality of life, and in reducing costs.

Return-to-work self-efficacy: development and validation of a scale in claimants with musculoskeletal disorders.

INTRODUCTION We report on the development and validation of a 10-item scale assessing self-efficacy within the return-to-work context, the Return-to-Work Self-Efficacy (RTWSE) scale. METHODS Lost-time claimants completed a telephone survey 1 month (n = 632) and 6 months (n = 446) after a work-related musculoskeletal injury. Exploratory (Varimax and Promax rotation) and confirmatory factor analyses of self-efficacy items were conducted with two separate subsamples at both time points. Construct validity was examined by comparing scale measurements and theoretically derived constructs, and the phase specificity of RTWSE was studied by examining changes in strength of relationships between the RTWSE Subscales and the other constructs at both time measures. RESULTS Factor analyses supported three underlying factors: (1) Obtaining help from supervisor, (2) Coping with pain (3) Obtaining help from co-workers. Internal consistency (alpha) for the three subscales ranged from 0.66 to 0.93. The total variance explained was 68% at 1-month follow-up and 76% at 6-month follow-up. Confirmatory factor analyses had satisfactory fit indices to confirm the initial model. With regard to construct validity: relationships of RTWSE with depressive symptoms, fear-avoidance, pain, and general health, were generally in the hypothesized direction. However, the hypothesis that less advanced stages of change on the Readiness for RTW scale would be associated with lower RTWSE could not be completely confirmed: on all RTWSE subscales, RTWSE decreased significantly for a subset of participants who started working again. Moreover, only Pain RTWSE was significantly associated with RTW status and duration of work disability. With regard to the phase specificity, the strength of association between RTWSE and other constructs was stronger at 6 months post-injury compared to 1 month post-injury. CONCLUSIONS A final 10-item version of the RTWSE has adequate internal consistency and validity to assess the confidence of injured workers to obtain help from supervisor and co-workers and to cope with pain. With regard to phase specificity, stronger associations between RTWSE and other constructs at 6-month follow-up suggest that the association between these psychological constructs consolidates over time after the disruptive event of the injury.

Validation of a risk factor-based intervention strategy model using data from the readiness for return to work cohort study.

BACKGROUND: Low back pain (LBP) is a common and in some cases disabling condition. Until recently, workers presenting with non-specific LBP have generally been regarded as a homogeneous population. If this population is not homogeneous, different interventions might be appropriate for different subgroups. We hypothesized that (1) Clusters of individuals could be identified based on risk factors, (2) These clusters would predict duration and recurrences 6 months post-injury. METHODS: The study focuses on the 442 LBP claimants in the Readiness for Return-to-Work Cohort Study. Claimants (n = 259) who had already returned to work, approximately 1 month post-injury were categorized as the low risk group. A latent class analysis was performed on 183 workers absent from work, categorized as the high risk group. Groups were classified based on: pain, disability, fear avoidance beliefs, physical demands, people-oriented culture and disability management practice at the workplace, and depressive symptoms. RESULTS: Three classes were identified; (1) workers with 'workplace issues', (2) workers with a 'no workplace issues, but back pain', and (3) workers having 'multiple issues' (the most negative values on every scale, notably depressive symptoms). Classes 2 and 3 had a similar rate of return to work, both worse than the rate of class 1. Return-to-work status and recurrences at 6 months were similar in all 3 groups. CONCLUSION: This study largely confirms that several subgroups could be identified based on previously defined risk factors as suggested by an earlier theoretical model by Shaw et al. (J Occup Rehab 16(4):591-605, 2006). Different groups of workers might be identified and might benefit from different interventions.

Workplace interventions for preventing work disability.

BACKGROUND: Work disability has serious consequences for all stakeholders and society. Workplace interventions are considered appropriate to facilitate return to work by reducing barriers to return to work, involving the collaboration of key stakeholders. OBJECTIVES: To determine the effectiveness of workplace interventions compared to usual care or clinical interventions on work-related outcomes and health outcomes; and to evaluate whether the effects differ when applied to musculoskeletal disorders, mental health problems, or other health conditions. SEARCH STRATEGY: We searched the Cochrane Occupational Health Field Trials Register, CENTRAL, MEDLINE and EMBASE (EMBASE.com), and PsycINFO databases (to November 2007). SELECTION CRITERIA: We included randomized controlled trials of workplace interventions aimed at return to work for workers where absence from work because of sickness was reported as a continuous outcome. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data and assessed risk of bias of the studies. Meta-analysis and qualitative analysis (using GRADE levels of evidence) were performed. MAIN RESULTS: We included six randomized controlled trials (749 workers): three on low back pain, one on upper-extremity disorders, one on musculoskeletal disorders, and one on adjustment disorders. Five studies were rated as having low risk of bias for the sickness absence outcome. The results of this review show that there is moderate-quality evidence to support the use of workplace interventions to reduce sickness absence among workers with musculoskeletal disorders when compared to usual care. However, workplace interventions were not effective to improve health outcomes among workers with musculoskeletal disorders. The lack of studies made it impossible to investigate the effectiveness of workplace interventions among workers with mental health problems and other health conditions. A comparison of a workplace intervention with a clinical intervention, in one study only, yielded similar results for sickness absence and symptoms for workers with mental health problems. AUTHORS' CONCLUSIONS: As a result of the few available studies, no convincing conclusions can be formulated about the effectiveness of workplace interventions on work-related outcomes and health outcomes regardless of the type of work disability. The pooled data for the musculoskeletal disorders subgroup indicated that workplace interventions are effective in the reduction of sickness absence, but they are not effective in improving health outcomes. The evidence from the subgroup analysis on musculoskeletal disorders was rated as moderate-quality evidence. Unfortunately, conclusions cannot be drawn on the effectiveness of these interventions for mental health problems and other health conditions due to a lack of studies.

Course, diagnosis, and treatment of depressive symptomatology in workers following a workplace injury: a prospective cohort study.

OBJECTIVES: To estimate prevalence, incidence, and course of depressive symptoms and prevalence of mental health treatment following a workplace injury, and to estimate the association between depressive symptoms and return-to-work (RTW) trajectories. METHOD: In a prospective cohort study, workers filing a lost-time compensation claim for a work-related musculoskeletal disorder of the back or upper extremity were interviewed 1 month (n = 599) and 6 months (n = 430) postinjury. A high level of depressive symptoms was defined as 16 or more on the self-reported Center for Epidemiologic Studies-Depression (CES-D) Scale. The following estimates are reported: prevalence of high depressive symptom levels at 1 and 6 months postinjury; incidence, resolution, and persistence of high depressive symptom levels between 1 and 6 months; and prevalence of self-reported mental health treatment and depression diagnosis at 6 months postinjury. RESULTS: Prevalence of high depressive symptom levels at 1 month and 6 months postinjury were 42.9% (95% CI 38.9% to 46.9%) and 26.5% (95% CI 22.3% to 30.7%), respectively. Among participants reporting high depressive symptom levels at 1 month postinjury, 47.2% (95% CI 39.9% to 54.5%) experienced a persistence of symptoms 6 months postinjury. By 6 months, 38.6% of workers who never returned to work or had work disability recurrences had high depressive symptom levels, compared with 17.7% of those with a sustained RTW trajectory. At 6-month follow-up, 12.9% (95% CI 5.8% to 20.1%) of participants with persistently high depressive symptom levels self-reported a depression diagnosis since injury and 23.8% (95% CI 14.7% to 32.9%) were receiving depression treatment. CONCLUSIONS: Depressive symptoms are pervasive in workers with musculoskeletal injuries, but transient for some, and seldom diagnosed as depression or treated.

Behavioral determinants as predictors of return to work after long-term sickness absence: an application of the theory of planned behavior.

BACKGROUND: The aim of this prospective, longitudinal cohort study was to analyze the association between the three behavioral determinants of the theory of planned behavior (TPB) model--attitude, subjective norm and self-efficacy--and the time to return-to-work (RTW) in employees on long-term sick leave. METHODS: The study was based on a sample of 926 employees on sickness absence (maximum duration of 12 weeks). The employees filled out a baseline questionnaire and were subsequently followed until the tenth month after listing sick. The TPB-determinants were measured at baseline. Work attitude was measured with a Dutch language version of the Work Involvement Scale. Subjective norm was measured with a self-structured scale reflecting a person's perception of social support and social pressure. Self-efficacy was measured with the three subscales of a standardised Dutch version of the general self-efficacy scale (ALCOS): willingness to expend effort in completing the behavior, persistence in the face of adversity, and willingness to initiate behavior. Cox proportional hazards regression analyses were used to identify behavioral determinants of the time to RTW. RESULTS: Median time to RTW was 160 days. In the univariate analysis, all potential prognostic factors were significantly associated (P < 0.15) with time to RTW: work attitude, social support, and the three subscales of self-efficacy. The final multivariate model with time to RTW as the predicted outcome included work attitude, social support and willingness to expend effort in completing the behavior as significant predictive factors. CONCLUSIONS: This prospective, longitudinal cohort-study showed that work attitude, social support and willingness to expend effort in completing the behavior are significantly associated with a shorter time to RTW in employees on long-term sickness absence. This provides suggestive evidence for the relevance of behavioral characteristics in the prediction of duration of sickness absence. It may be a promising approach to address the behavioral determinants in the development of interventions focusing on RTW in employees on long-term sick leave.

"So, are you back to work yet?" Re-conceptualizing 'work' and 'return to work' in the context of primary bone cancer.

People with primary bone cancer typically are young (usual age-at-onset 16-35 years old) and undergo arduous treatments. The current standard of care (tumour resection and limb reconstruction with or without chemotherapy) results in survival rates in excess of 60%, but also results in significant disability at a time when patients are choosing career paths, establishing their independence and embarking on new roles. To date, the nature of the relationship between experiences of osteosarcoma illness and experiences of vocation has remained unclear. This study sought to examine this relationship using qualitative narrative methodology. In-depth audiotaped interviews were conducted with 14 osteosarcoma survivors (8 men, 6 women) who were being treated at Mount Sinai Hospital, Toronto, Canada. Interview transcripts were analyzed for story typology and thematic content via constant comparison. Respondents reported engaging in three types of 'work': 'illness work', 'identity work' and 'vocational work'. Osteosarcoma illness represented a crisis for respondents, one which necessitated considerable illness work. Illness work was portrayed as all-consuming, whereby respondents were forced to stop vocational work for considerable periods. The illness crisis also precipitated 'identity work'. Respondents recounted a transformative process, of 'becoming other' to whom they had been prior to illness. As a result, respondents told of re-entering the vocational sphere with a different sense of themselves from when they left it. When patients return for surgical follow up, clinicians routinely ask, "So, are you back to work yet?" expecting simple 'yes/no' answers. This study suggests that the answer is instead highly complex, and that patients could be seen as having been 'working' all along. This study offers a re-conceptualization of 'work' and 'return to work' in the context of osteosarcoma, with implications for clinical and return-to-work practices.

Examining Exposure Assessment in Shift Work Research: A Study on Depression Among Nurses.

Introduction: Coarse exposure assessment and assignment is a common issue facing epidemiological studies of shift work. Such measures ignore a number of exposure characteristics that may impact on health, increasing the likelihood of biased effect estimates and masked exposure-response relationships. To demonstrate the impacts of exposure assessment precision in shift work research, this study investigated relationships between work schedule and depression in a large survey of Canadian nurses. Methods: The Canadian 2005 National Survey of the Work and Health of Nurses provided the analytic sample (n = 11450). Relationships between work schedule and depression were assessed using logistic regression models with high, moderate, and low-precision exposure groupings. The high-precision grouping described shift timing and rotation frequency, the moderate-precision grouping described shift timing, and the low-precision grouping described the presence/absence of shift work. Final model estimates were adjusted for the potential confounding effects of demographic and work variables, and bootstrap weights were used to generate sampling variances that accounted for the survey sample design. Results: The high-precision exposure grouping model showed the strongest relationships between work schedule and depression, with increased odds ratios [ORs] for rapidly rotating (OR = 1.51, 95% confidence interval [CI] = 0.91-2.51) and undefined rotating (OR = 1.67, 95% CI = 0.92-3.02) shift workers, and a decreased OR for depression in slow rotating (OR = 0.79, 95% CI = 0.57-1.08) shift workers. For the low- and moderate-precision exposure grouping models, weak relationships were observed for all work schedule categories (OR range 0.95 to 0.99). Conclusions: Findings from this study support the need to consider and collect the data required for precise and conceptually driven exposure assessment and assignment in future studies of shift work and health. Further research into the effects of shift rotation frequency on depression is also recommended.

Systematic review of the qualitative literature on return to work after injury.

OBJECTIVES: This paper reports on a systematic review of the international qualitative research literature on return to work. This review was undertaken in order to better understand the dimensions, processes, and practices of return to work. Because return to work often includes early return before full recovery while a person is undergoing rehabilitation treatment, physical recovery is embedded in complicated ways with workplace processes and practices and social organization. These process-oriented dimensions of return to work are well described in the qualitative literature. METHODS: This systematic review of the literature covered peer-reviewed papers that focused on musculoskeletal and pain-related injuries and were published in English or French between 1990 and 2003. Findings from papers meeting relevance and quality criteria were synthesized using the meta-ethnographic approach. RESULTS: This review found that return to work extends beyond concerns about managing physical function to the complexities related to beliefs, roles, and perceptions of many players. Good will and trust are overarching conditions that are central to successful return-to-work arrangements. In addition, there are often social and communication barriers to return to work, and intermediary players have the potential to play a key role in facilitating this process. CONCLUSIONS: This paper identifies key mechanisms of workplace practice, process, and environment that can affect the success of return to work. The findings illustrate the contribution that qualitative literature can make to important aspects of implementation in relation to return to work.

Examining the relationship between work-family spillover and sleep quality.

The present study examined the relationship between work-family spillover, job characteristics, and sleep quality in a sample of health care workers (N = 168) recruited from 3 Canadian hospitals. A multiple regression analysis revealed that positive family-to-work spillover is associated with better sleep quality, after controlling for age, physical health, depressive symptomatology, work situation, and number of children. These findings are discussed within a theoretical framework drawing on the concepts of effort and recovery.

Cardiac rehabilitation I: review of psychosocial factors.

Cardiovascular disease (CVD) is the leading cause of death and disability for women and men. There are gender differences in recovery from coronary events, which may be due physiological, sociodemographic, or psychosocial factors. Cardiac rehabilitation programs have beneficial effects on coronary recovery. The following presents a review of the literature from MedLine (1997-2001) and PsychInfo (1984-2001) on gender differences in participation in cardiac rehabilitation programs, with a focus on depression, anxiety, self-efficacy and social support. A critical analysis of gaps in the literature as well as areas for future research are presented.
