Perceived Injustice as a Determinant of the Severity of Post-traumatic Stress Symptoms Following Occupational Injury.

BACKGROUND: The present study assessed the role of perceived injustice in the experience and persistence of post-traumatic stress symptoms (PTSS) following work-related musculoskeletal injury. METHODS: The study sample consisted of 187 individuals who were absent from work as a result of a musculoskeletal injury. Participants completed measures of pain severity, perceived injustice, catastrophic thinking, post-traumatic stress symptoms, and disability on three occasions at three-week intervals. RESULTS: Consistent with previous research, correlational analyses revealed significant cross-sectional relations between pain and PTSS, and between perceived injustice and PTSS. Regression analysis on baseline data revealed that perceived injustice contributed significant variance to the prediction of PTSS, beyond the variance accounted for by pain severity and catastrophic thinking. Sequential analyses provided support for a bi-directional relation between perceived injustice and PTSS. Cross-lagged regression analyses showed that early changes in perceived injustice predicted later changes in PTSS and early changes in PTSS predicted later changes in perceived injustice. CONCLUSIONS: Possible linkages between perceived injustice and PTSS are discussed. The development of effective intervention techniques for targeting perceptions of injustice might be important for promoting recovery of PTSS consequent to musculoskeletal injury.

Qualitative Examination of the Experience of Perceived Injustice Following Disabling Occupational Injury.

PURPOSE: The primary objective of this study was to explore individuals' perspectives on the factors, situations or events that contributed to their perceptions of injustice following occupational injury. MATERIALS AND METHODS: The study sample consisted of 30 participants (18 women, 12 men) who had submitted a time-loss claim for a work-related musculoskeletal injury. Participants with elevated scores on a measure of perceived injustice were interviewed about the factors that contributed to their sense of injustice. A thematic analysis was conducted to identify the broad classes of situations or events that participants experienced as unjust in the weeks following occupational injury. RESULTS: Three dominant themes emerged from the interviews: (1) Invalidation, (2) Undeserved suffering and (3) Blame. Inductively derived subthemes reflected specific dimensions of post-injury experiences that contributed to participants' sense of injustice. CONCLUSIONS: Given that suffering and invalidating communication are potentially modifiable factors, there are grounds for optimism that intervention approaches can be developed to prevent or reduce perceptions of injustice in the aftermath of debilitating injury. The development of intervention approaches that are effective in preventing or reducing perceptions of injustice holds promise of contributing to more positive recovery outcomes in individuals who have sustained debilitating work injuries.

Nursing students' academic conditions, psychological distress, and intention to leave school: A cross-sectional study.

BACKGROUND: Psychological distress and intention to leave school are highly prevalent among nursing students. Academic conditions, including psychosocial stressors and school-work-life conflicts, could contribute to psychological distress and intention to leave school. OBJECTIVE: To explore the associations between academic conditions and 1) psychological distress and 2) intention to leave school. DESIGN: Cross-sectional correlational design. SETTINGS: Data collection was performed in February and October 2021 in two nursing schools in Canada: Cegep (publicly funded college, technical degree) and university (bachelor's degree). PARTICIPANTS: 230 nursing students (Cegep 131, university 99). METHODS: A self-administered online questionnaire assessed academic conditions (psychosocial stressors (Demand-Control-Support, Effort-Reward Imbalance and Overcommitment scales) and school-work-life conflicts (single item)), psychological distress (Kessler-6 scale), intention to leave school, and several covariates. Poisson robust multivariate regression models were built to explore the associations between academic conditions and 1) psychological distress and 2) intention to leave school. RESULTS: A large proportion of participants experienced high efforts, school-work-life conflicts, overcommitment, and psychological distress (49.5-84.7 %). One out of five participants had had intention to leave school "many times" (Cegep 20.61 %; university 22.22 %). In adjusted analysis, overcommitment and school-work-life conflicts were associated with a higher prevalence of psychological distress (Prevalence ratio = 2.10; 95 % Confidence Intervals = 1.15-3.84 and Prevalence ratio = 2.32; 95 % Confidence Intervals = 1.24-4.32, respectively). Adverse associations were observed between effort-reward imbalance (Prevalence ratio = 2.32; 95 % Confidence Intervals = 1.09-4.94) as well as school-work-life conflicts (Prevalence ratio = 2.40; 95 % Confidence Intervals = 1.05-5.45) and intention to leave school. CONCLUSIONS: Academic conditions might be risk factors for psychological distress and intention to leave school among nursing students. Interventions targeting modifiable academic conditions might improve nursing students' mental health and retention.

Absenteeism screening questionnaire (ASQ): a new tool for predicting long-term absenteeism among workers with low back pain.

INTRODUCTION: Over the last decades, psychosocial factors were identified by many studies as significant predictive variables in the development of disability related to common low back disorders, which thus contributed to the development of biopsychosocial prevention interventions. Biopsychosocial interventions were supposed to be more effective than usual interventions in improving different outcomes. Unfortunately, most of these interventions show inconclusive results. The use of screening questionnaires was proposed as a solution to improve their efficacy. The aim of this study was to validate a new screening questionnaire to identify workers at risk of being absent from work for more than 182 cumulative days and who are more susceptible to benefit from prevention interventions. METHODS: Injured workers receiving income replacement benefits from the Quebec Compensation Board (n = 535) completed a 67-item questionnaire in the sub-acute stage of pain and provided information about work-related events 6 and 12 months later. Reliability and validity of the 67-item questionnaire were determined respectively by test-retest reliability and internal consistency analysis, as well as by construct validity analyses. The Cox regression model and the maximum likelihood method were used to fix a model allowing calculation of a probability of absence of more than 182 days. Criterion validity and discriminative capacity of this model were calculated. RESULTS: Sub-sections from the 67-item questionnaire were moderately to highly correlated 2 weeks later (r = 0.52-0.80) and showed moderate to good internal consistency (0.70-0.94). Among the 67-item questionnaire, six sub-sections and variables (22 items) were predictive of long-term absence from work: fear-avoidance beliefs related to work, return to work expectations, annual family income before-taxes, last level of education attained, work schedule and work concerns. The area under the ROC curve was 73%. CONCLUSIONS: The significant predictive variables of long-term absence from work were dominated by workplace conditions and individual perceptions about work. In association with individual psychosocial variables, these variables could contribute to identify potentially useful prevention interventions and to reduce the significant costs associated with LBP long-term absenteeism.

Stressors experienced by nurses providing end-of-life palliative care in the intensive care unit.

The purpose of this study was to describe stressors experienced by nurses in providing end-of-life palliative care (EoL/PC) in intensive care units (ICUs). A descriptive qualitative design was used. A total of 42 nurses from 5 ICUs in the province of Quebec, Canada, participated in 10 focus groups. Stressors were found to be clustered in 3 categories: organizational, professional, and emotional. The major organizational stressors were lack of a palliative care approach, interprofessional difficulty, lack of continuity in life-support and treatment plans, and conflicting demands. Professional stressors included lack of EoL/PC competencies and difficulty communicating with families and collaborating with the medical team. Emotional stressors were described as value conflicts, lack of emotional support, and dealing with patient and family suffering.The authors conclude that providing EoL/PC is stressful for ICU nurses and that education and support programs should be developed to ensure quality EoL/PC in the critical care environment.

Use of Mobile Apps and Online Programs of Mindfulness and Self-Compassion Training in Workers: A Scoping Review.

Mindfulness and self-compassion interventions are two strategies helpful in preventing and reducing burnout and work stress. However, professionals with overburdened schedules can experience obstacles in learning and practicing these interventions, originally taught with lengthy programs. The use of digital technologies could make these interventions more accessible to workers, as studied in a recent, growing body of evidence. The evidence available is diverse in terms of interventions, designs, outcomes, and populations. This calls for a review that can take into consideration this diversity while still rigorously synthesize it. Scoping reviews are designed to examine emerging evidence and summarize the evidence on a specific topic of interest. The present scoping review aims to assess the current state of the literature on the use of online programs and mobile applications of self-compassion, mindfulness, and meditation (digital mindfulness-based interventions; dMBIs) by workers. More specifically, information on the type of intervention, population, advantages, and disadvantages, measured outcomes, and advice for future research are gathered. MEDLINE (PubMed; Ovid), PsychInfo (Ovid), and Web of Science (Clarivate) were searched to identify all relevant articles. The screening process resulted in 56 articles being included in this scoping review. Inclusion criteria were (1) participants are workers; (2) the intervention is individual, digital, and mindfulness/self-compassion/meditation-based; and (3) articles were available in French or English language at the time of the review. Interventions used were mostly mindfulness-based, equally categorized under web-based and app-based interventions. Most interventions included information on mindfulness, meditation or self-compassion, meditation exercises, other types of exercises, instructions on how to use, and reminders. dMBIs are often studied in the healthcare population and predominantly in female samples. Although dMBIs present advantages (low cost, accessibility, practicality, feasibility), obstacles can arise in their implementation (low engagement and motivation, concerns about confidentiality). Included articles measured outcomes related to work, mindfulness or self-compassion, and other psychological variables (stress/anxiety, depression, resilience, wellbeing). Articles provided important directions to further research on dMBIs regarding methodological aspects, modality and intervention, and individual and organizational questions. dMBIs are becoming more popular and interventions are diverse. Although not without limitations, this scoping provided a synthesis on different aspects of the use of dMBIs within workers and highlighted pertinent future research directions.

Associations between psychosocial stressors at work and moral injury in frontline healthcare workers and leaders facing the COVID-19 pandemic in Quebec, Canada: A cross-sectional study.

Healthcare workers (HCWs) on the frontline of the COVID-19 pandemic exhibit a high prevalence of depression and psychological distress. Moral injury (MI) can lead to such mental health problems. MI occurs when perpetrating, failing to prevent, or bearing witness to acts that transgress deeply held moral beliefs and expectations. Since the start of the pandemic, psychosocial stressors at work (PSWs) might have been exacerbated, which might in turn have led to an increased risk of MI in HCWs. However, research into the associations between PSWs and MI is lacking. Considering these stressors are frequent and most of them are modifiable occupational risk factors, they may constitute promising prevention targets. This study aims to evaluate the associations between a set of PSWs and MI in HCWs during the third wave of the COVID-19 pandemic in Quebec, Canada. Furthermore, our study aims to explore potential differences between urban and non-urban regions. The sample of this study consisted of 572 HCWs and leaders from the Quebec province. Prevalence ratios (PR) of MI and their 95% confidence intervals (CI) were modelled using robust Poisson regressions. Several covariates were considered, including age, sex, gender, socio-economic indicators, and lifestyle factors. Results indicated HCWs exposed to PSWs were 2.22-5.58 times more likely to experience MI. Low ethical culture had the strongest association (PR: 5.58, 95% CI: 1.34-23.27), followed by low reward (PR: 4.43, 95% CI: 2.14-9.16) and high emotional demands (PR: 4.32, 95% CI: 1.89-9.88). Identifying predictors of MI could contribute to the reduction of mental health problems and the implementation of targeted interventions in urban and non-urban areas.

Predict, prevent and manage moral injuries in Canadian frontline healthcare workers and leaders facing the COVID-19 pandemic: Protocol of a mixed methods study.

Moral injuries can occur when perpetrating, failing to prevent, or bearing witness to acts that transgress deeply held moral beliefs and expectations. The COVID-19 crisis highlighted the fact that psychosocial stressors at work, such as high emotional demands, are placing Canadian healthcare workers at risk of moral injuries. Evidence linking psychosocial stressors at work to moral injuries are needed to better predict, prevent and manage moral injuries, as these stressors are frequent and modifiable occupational risk factors. This protocol presents a study aiming to: 1) understand workplace events having the potential to either cause or reduce moral injuries, 2) predict the risk and severity of moral injuries using a disease prevention model, 3) identify biological signatures (biomarkers) associated with psychosocial stressors at work and moral injuries and 4) elaborate preliminary guidelines of organizational practices for frontline healthcare workers to reduce and manage moral injuries. This study is a mixed methods research with three components: qualitative, quantitative and biological. The data collection has been completed and because of the COVID-19 pandemic, it was adjusted to allow for gathering qualitative and quantitative data remotely. Frontline healthcare workers and leaders were included. Through focus groups and individual interviews, and an online questionnaire, events and psychosocial working conditions that may increase the risk of moral injuries will be documented. In addition, blood samples which were collected from a sub-sample of volunteer participants will measure an innovative set of biomarkers associated with vulnerability to stress and mental health. Data analyses are ongoing. We anticipate to identify workplace events that may trigger moral injuries. We expect that potential predictors of moral injury risk occurrence and severity will be identified from psychosocial stressors at work that can be improved by implementing organizational practices. We also expect to observe a different mental health state and biological inflammation signature across workers exposed compared to workers not exposed to psychosocial stressors at work. Based on these future findings, we intend to develop preliminary recommendations of organizational practices for managers. This research will contribute to expand our knowledge of the events in the workplace likely to generate or lessen the impact moral injuries, to build a model for predicting the risk of moral injuries at work, all in the specific context of the COVID-19 health crisis among healthcare workers.

Insurers' perspective on barriers and facilitators for return to work after occupational injuries.

BACKGROUND: Despite the importance of the legislative and insurance systems in the return to work process after an occupational injury, the perspective of the insurer on what influences return to work has rarely been documented. OBJECTIVE: To understand the barriers or facilitators for return to work, from the perspective of the insurer. METHODS: A comprehensive qualitative approach was used. Semi-directed interviews were done with nineteen (19) insurers (claims adjudicator and rehabilitation case manager) from a Canadian workers' compensation board. A thematic analysis was done using QDA Minor Software. RESULTS: Fourteen themes (e.g. family reaction, quality of work relationship) were classified into four categories representing the main stakeholders: worker with disability, workplace, healthcare system and compensation system. Emotional, cognitive, and adaptive reactions from the worker and his family were identified. We observed that good work relations and support practices, lack of access to medical resources, focus on the employee's ability, and complexity and consequences of the compensation process are the main barriers and facilitators from the insurers' perspective. Many of the perceived elements are coherent with the compensation system's administrative and legal context. CONCLUSIONS: The results enable us to better understand the insurers' perspective regarding what influences return to work. It reinforces the necessity to consider the administrative and legal context to better understand the insurers' perspective.

An interdisciplinary clinical practice model for the management of low-back pain in primary care: the CLIP project.

BACKGROUND: Low-back pain is responsible for significant disability and costs in industrialized countries. Only a minority of subjects suffering from low-back pain will develop persistent disability. However, this minority is responsible for the majority of costs and has the poorest health outcomes. The objective of the Clinic on Low-back pain in Interdisciplinary Practice (CLIP) project was to develop a primary care interdisciplinary practice model for the clinical management of low-back pain and the prevention of persistent disability. METHODS: Using previously published guidelines, systematic reviews and meta-analyses, a clinical management model for low-back pain was developed by the project team. A structured process facilitating discussions on this model among researchers, stakeholders and clinicians was created. The model was revised following these exchanges, without deviating from the evidence. RESULTS: A model consisting of nine elements on clinical management of low-back pain and prevention of persistent disability was developed. The model's two core elements for the prevention of persistent disability are the following: 1) the evaluation of the prognosis at the fourth week of disability, and of key modifiable barriers to return to usual activities if the prognosis is unfavourable; 2) the evaluation of the patient's perceived disability every four weeks, with the evaluation and management of barriers to return to usual activities if perceived disability has not sufficiently improved. CONCLUSION: A primary care interdisciplinary model aimed at improving quality and continuity of care for patients with low-back pain was developed. The effectiveness, efficiency and applicability of the CLIP model in preventing persistent disability in patients suffering from low-back pain should be assessed.

Psychosocial and socio-demographic factors associated with outcomes for patients undergoing rehabilitation for chronic whiplash associated disorders: a pilot study.

PURPOSE: Identify psychosocial and socio-demographic factors (measured prior to treatment) that were associated with post-treatment self-perceived pain and disability and two secondary outcomes: psychological distress, and return to work in patients undergoing multidisciplinary rehabilitation for chronic whiplash associated disorders (WAD). METHOD: Interviews were conducted with 28 patients with chronic WAD at entry to and completion of an intensive rehabilitation program, and a telephone interview was carried out three months later. Participants completed pain and disability, and psychological distress questionnaires, at baseline and at both follow-ups. They also completed psychosocial questionnaires and provided socio-demographic information. The effect of each of the independent variables on the outcomes was first evaluated by simple regressions, and then subsequently by multiple regression analysis. RESULTS: Higher baseline pain and disability predicted higher pain and disability at both follow-ups (p < 0.001), and higher psychological distress at program completion (p = 0.003). Younger age (p = 0.028) and higher baseline psychological distress (p = 0.002) were associated with higher psychological distress three months post-rehabilitation. Greater social support at work was prognostic of return to work at program completion (p = 0.04). CONCLUSIONS: Baseline pain and disability was the only factor that affected pain and disability post-rehabilitation. Psychosocial factors played a role in the prognosis of psychological distress and return to work.

The Chronic Pain Coping Inventory: confirmatory factor analysis of the French version.

BACKGROUND: Coping strategies are among the psychosocial factors hypothesized to contribute to the development of chronic musculoskeletal disability. The Chronic Pain Coping Inventory (CPCI) was developed to assess eight behavioral coping strategies targeted in multidisciplinary pain treatment (Guarding, Resting, Asking for Assistance, Task Persistence, Relaxation, Exercise/Stretch, Coping Self-Statements and Seeking Social Support). The present study had two objectives. First, it aimed at measuring the internal consistency and the construct validity of the French version of the CPCI. Second, it aimed to verify if, as suggested by the CPCI authors, the scales of this instrument can be grouped according to the following coping families: Illness-focused coping and Wellness-focused coping. METHOD: The CPCI was translated into French with the forward and backward translation procedure. To evaluate internal consistency, Cronbach's alphas were computed. Construct validity of the inventory was estimated through confirmatory factor analysis (CFA) in two samples: a group of 439 Quebecois workers on sick leave in the sub-acute stage of low back pain (less than 84 days after the work accident) and a group of 388 French chronic pain patients seen in a pain clinic. A CFA was also performed to evaluate if the CPCI scales were grouped into two coping families (i.e. Wellness-focused and Illness-focused coping). RESULTS: The French version of the CPCI had adequate internal consistency in both samples. The CFA confirmed the eight-scale structure of the CPCI. A series of second-order CFA confirmed the composition of the Illness-focused family of coping (Guarding, Resting and Asking for Assistance). However, the composition of the Wellness-focused family of coping (Relaxation, Exercise/Stretch, Coping Self-Statements and Seeking Social Support) was different than the one proposed by the authors of the CPCI. Also, a positive correlation was observed between Illness and Wellness coping families. CONCLUSION: The present study indicates that the internal consistency and construct validity of the French version of the CPCI were adequate, but the grouping and labeling of the CPCI families of coping are debatable and deserve further analysis in the context of musculoskeletal and pain rehabilitation.

Work-related factors contributing to chronic disability in low back pain.

Low back pain is a costly and incapacitating musculoskeletal disorder. Prospective studies documenting the capacity of work-related factors to predict chronicity are few in number, the methodology used is very diversified, and the results obtained diverge. The aim of the present study is to investigate the capacity of work-related objective (non-psychosocial) and psychosocial factors to predict chronic disability related to low back pain. A longitudinal prospective study with two measurement times was carried out. The sample (N = 258) consisted of workers with subacute low back pain who were on sick leave and receiving compensation from the CSST (Quebec Workers' Compensation Board). Of all the work-related variables measured, perceived stress and fears and beliefs about work were associated with return to work status at the six-month follow-up. The results obtained show the importance of considering fears and beliefs about work when identifying people in the subacute phase of low back pain who are at risk of developing chronic disability.

Predictive validity of the Chronic Pain Coping Inventory in subacute low back pain.

The Chronic Pain Coping Inventory (CPCI) was developed to assess eight behavioral coping strategies hypothesized to be important for pain adaptation. But the predictive validity of the CPCI has yet to be tested in a longitudinal study. Here, 321 workers on sick leave after a work accident affecting the low back pain (LBP) region completed the CPCI during the subacute stage (T1) of LBP as well as the Catastrophizing scale of the Coping Strategies Questionnaire (CSQ). Disability, pain intensity and depressive mood were assessed simultaneously as well as 6 months later (T2). Work status was also determined at follow-up. Hierarchical regression analyses revealed that the CPCI (Guarding scale) predicted T1 disability and T2 disability (Relaxation scale), but T1 disability was the best predictor of T2 disability. For T1 pain intensity, the CSQ's Catastrophizing dimension was the best predictor and the CPCI Guarding scale added a small contribution. T1 pain intensity was the best predictor of T2 pain intensity. Catastrophizing and Guarding were the most strongly associated with depressive mood at T1 but at T2, only depressive mood at T1 predicted this same variable. Results indicated also that the Guarding and Catastrophizing scales were able to predict future work status. The present study clearly reveals the usefulness of Guarding from the CPCI and Catastrophizing from the CSQ, when predicting different outcomes of adjustment to low back pain.

Effects of patient--clinician disagreement in occupational low back pain: a pilot study.

PURPOSE: To determine (1) patient--physical therapist and patient--physician agreement on clinical management of LBP, (2) patient perception of agreement between physical therapist and physician, (3) association between agreement and outcome (return to work, self-perceived disability). METHOD: Thirty-five workers compensated for LBP responded to a telephone interview within 1 week of referral to physical therapy. They were asked about agreement with the physical therapist and the physician regarding the clinical management of their LBP and whether they thought the physical therapist was providing the treatment the physician would have thought appropriate. They completed a second interview upon returning to work or after 3 months. They answered questionnaires on self-perceived disability, psychological distress, coping strategies, and job satisfaction at both baseline and follow-up. RESULTS: Nearly all patients (97.1%) agreed with the physical therapist and all believed the physical therapist was providing the treatment the physician would have thought appropriate. The 10 (28.6%) patients who disagreed with their physician on medical management of their LBP were less satisfied with the medical care (P=0.05), technical quality of the visit (P=0.01), and catastrophized more about their pain (P=0.03) than those who agreed. Disagreement was not associated with greater time off-work or greater self-perceived disability. CONCLUSION: Patients who disagreed with their physician were less satisfied with their medical management, and catastrophized more about their pain than those who agreed, but disagreement was not associated with chronicity or disability. Studies with larger sample sizes should investigate the role of other factors, such as patient expectations, in the transition to chronicity.

Validation of a French Canadian version of the Organizational Policies and Practices (OPP) questionnaire.

Organizational factors are potentially powerful in accounting for work-related chronic disability following a musculoskeletal disorder. This study documents the psychometric qualities of the French Canadian version of the Organizational Policies and Practices questionnaire (OPP) [1] on a population of nurses (N=124). By excluding the two items composing the ergonomic practices factor, a factorial structure identical to that obtained by the OPP's authors is obtained for the disability management policies and practices factor, the people-oriented culture factor and the safety climate factor. The internal consistency coefficients (Cronbach's alpha) are satisfactory while the coefficients intraclass are less than those obtained by the authors in the test-retest. However, the test-retest interval is greater in this study. Consistent relationships are observed between the dimensions of the OPP and three job-related psychosocial indicators: perceived stress, social support and satisfaction. This suggests a good construct validity for the OPP. Although additional validation efforts are recommended, all of the results obtained support the validity and reliability of the French Canadian version of the OPP. This version can be used to examine the importance of organizational aspects in studies on the prevention of chronic disability.

Validation of an adaptation of the stress process model for predicting low back pain related long-term disability outcomes: a cohort study.

STUDY DESIGN: Twelve-month cohort study. OBJECTIVE: The aim of the study was to examine the ability of an adaptation of the stress process model to predict different outcomes among low back pain (LBP) sufferers. SUMMARY OF BACKGROUND DATA: Recently, the stress process model was adapted and was shown to be useful to partially explain long-term disability related to low back pain, an important occupational health problem. METHODS: French-speaking compensated workers on sick leave because of subacute common LBP (N=439) completed a questionnaire including the adapted stress process model's factors: life events and appraisal, cognitive appraisal of LBP, emotional distress, avoidance coping strategies, and functional disability. Six and 12 months later, participants gave information about their work status, number of days of absence, and functional disability. Regression analyses were performed to identify significant predictive factors of these outcomes. Pain intensity, fear of work, gender, and presence of pain radiating below the knee were used as control variables. RESULTS: Number of days of absence, functional disability, and absence from work were predicted at 6 and 12 months by cognitive appraisal of LBP and emotional distress. Functional disability was predicted in addition by functional disability at study entry (T1). When the control variables were considered, number of days of absence was predicted at 6 months by cognitive appraisal, fear of work, and being a male, and, in addition, by emotional distress at 12 months. Functional disability was predicted by functional disability t1, emotional distress, cognitive appraisal of LBP, and fear of work at 6 months, and by the same factors and variables at 12 months, except for functional disability t1. Regarding absence from work, it was predicted at 6 months by fear of work and being a male, and at 12 months by cognitive appraisal of LBP and fear of work. CONCLUSION: In association with fear of work, 2 factors from the adapted stress process model are significantly useful for predicting LBP related long-term disability outcomes and could be targeted by preventive interventions.

Low-back-pain related disability: an integration of psychological risk factors into the stress process model.

The purpose of this study was to verify the usefulness of an adaptation of the stress process model in organizing the psychological variables associated with the development of low-back-pain related disability. French-speaking Canadian workers on compensated sick leave (N=439) due to recent occupational low back pain (LBP) were evaluated during the sub-acute stage of LBP (between 30 and 83 days after injury). They were assessed for the following factors: life events, injury-specific cognitive appraisal, emotional distress, avoidance coping, and functional disability. Confirmatory factor analyses were used to test and modify the measurement model. An important modification in the measurement model was the association of catastrophizing with the emotional distress factor. During the sub-acute stage, path analyses revealed a satisfactory fit of the following model (the following coefficients are standardized): (a) life events (.30) and cognitive appraisal (.42) explained emotional distress (r(2)=.30); (b) emotional distress (.42) and cognitive appraisal (.36) explained the use of avoidance coping (r(2)=.45); and (c) emotional distress (.24) and avoidance coping (.56) explained functional disability (r(2)=.53). The stress model tested here reaffirms the importance of life events in the development of disability through the more established emotional distress factor. Also, cognitive appraisal appears to have an indirect effect on disability through activity avoidance and distress. This adaptation of the stress model makes it possible to integrate risk factors into a reduced set of meaningful factors and proposes a more general adaptation explanation of disability than the specific fear-avoidance model.

An interdisciplinary guideline development process: the Clinic on Low-back pain in Interdisciplinary Practice (CLIP) low-back pain guidelines.

BACKGROUND: Evaluation of low-back pain guidelines using Appraisal of Guidelines Research and Evaluation (AGREE) criteria has shown weaknesses, particularly in stakeholder involvement and applicability of recommendations. The objectives of this project were to: 1) develop a primary care interdisciplinary clinical practice guideline aimed at preventing prolonged disability from low-back pain, using a community of practice approach, and 2) assess the participants' impressions with the process, and evaluate the relationship between participant characteristics and their participation. METHODS: Ten stakeholder representatives recruited 136 clinicians to participate in this community of practice. Clinicians were drawn from the following professions: physiotherapists (46%), occupational therapists (37%), and family physicians (17%). Using previously published guidelines, systematic reviews, and meta-analyses, a first draft of the guidelines was presented to the community of practice. Four communication tools were provided for discussion and exchanges with experts: a web-based discussion forum, an anonymous comment form, meetings, and a symposium. Participants were prompted for comments on interpretation, clarity, and applicability of the recommendations. Clinical management recommendations were revised following these exchanges. At the end of the project, a questionnaire was sent to the participants to assess satisfaction towards the guidelines and the development process. RESULTS: Twelve clinical management recommendations on management of low-back pain and persistent disability were initially developed. These were discussed through 188 comments posted on the discussion forum and 103 commentary forms submitted. All recommendations were modified following input of the participants. A clinical algorithm summarizing the guidelines was also developed. A response rate of 75% was obtained for the satisfaction questionnaire. The majority of respondents appreciated the development process and agreed with the guideline content. Most participants thought recommendations improved between versions, and that participant comments contributed to this improvement. All stakeholders officially endorsed the guidelines. CONCLUSION: The community of practice approach was a successful method to develop guidelines on low-back pain, with participants providing information to improve guideline recommendations. The information technology infrastructure that was developed remains for continuous interdisciplinary exchanges and updating of the guidelines.
