Abstract: A novel prognostic approach to defining chronic pain was developed in a US primary care low back pain population, using a combination of information about pain history, current status and likely prognosis. We tested whether this method was generalisable to a UK population. A prospective cohort of 426 patients who consulted with back pain at one of five UK general practices, and who returned follow-up information 1-year later were included. A baseline risk score was calculated based on pain severity and prognostic measures (depression, diffuse pain, pain duration), and cut-points from the US study applied for the risk of future clinically significant back pain, as defined by Chronic Pain Grades 2–4. New cut-points were also derived for the UK population using identical methods. The cut-points for probable and possible chronic pain developed in the US population (80% and 50% probability of future clinically significant back pain, respectively) were appropriate for the UK population, but the cut-point for classifying people at low risk (20% probability) was not replicated in the UK sample. The newly derived cut-points in the UK sample were similar; they remained the same for probable chronic pain, were slightly increased for possible chronic pain, and slightly reduced for those at intermediate or low risk. This method for defining chronic pain prospectively, using risk thresholds for future clinically significant pain, appears to be generalisable to a UK back pain population, particularly for identifying probable chronic pain, and may be generalisable to other primary care low back pain populations.

Background and aims: In the spring of 2019, Professor Steven J. Linton, the founder of the Center for Health and Medical Psychology (CHAMP) at Örebro University, Sweden, formally retired. As a tribute to his scholarly work covering decades of influence and inspiration to the field of pain psychology, the research center organized a topical conference titled "Pain in the 21st century: Where do we come from and where are we going?", which resulted in this state-of the-art synthesis. The aim of this declaration is to highlight lessons learned but not in the least is meant to inspire and guide our continued journey forward, developing pain psychology into the 21st century. Methods: Several collaborators of Professor Linton have summarized and reflected on the current state-of-the-art of pain psychology from the perspective of his input to the field, as well as on developments from the last years of advancements in pain psychology. Results: The topics have been divided into six themed sections covering the fear avoidance model, transdiagnostics, secondary prevention, risk- and protective factors, communication and contextual factors. The sections cover a broad spectrum, from basic experimental studies, integrating emotion and motivational theories into current theoretical models, to applied research on the effect of early interventions as well as sophisticated emotion-focused treatment models for pain patients with concurrent emotional ill-health. Conclusions: There have been major advancements within pain psychology research during the last decades, moving the field towards a more comprehensive picture, taking emotional and motivational aspects into account to understand pain sufferers. Although psychologically informed interventions in general mainly focus on the individual, it has been put forward that pain management is highly influenced by the surrounding environment, including communication with health care providers, and the occupational and social context. Implications: Professor Steven J. Linton has been at the forefront of pain psychology research during the last decades, and inspired by his work this journey will continue into the 21st century, with the ultimate goal of enhancing the understanding and treatment for all people suffering from persistent and disabling pain.

Background: Statistical analysis plans increase the transparency of decisions made in the analysis of clinical trial results. The purpose of this paper is to detail the planned analyses for the PREVENT trial, a randomized, placebo-controlled trial of patient education for acute low back pain. Results: We report the pre-specified principles, methods, and procedures to be adhered to in the main analysis of the PREVENT trial data. The primary outcome analysis will be based on Mixed Models for Repeated Measures (MMRM), which can test treatment effects at specific time points, and the assumptions of this analysis are outlined. We also outline the treatment of secondary outcomes and planned sensitivity analyses. We provide decisions regarding the treatment of missing data, handling of descriptive and process measure data, and blinded review procedures. Conclusions: Making public the pre-specified statistical analysis plan for the PREVENT trial minimizes the potential for bias in the analysis of trial data, and in the interpretation and reporting of trial results.

Abstract: The biopsychosocial model is increasingly accepted in low back pain (LBP) research and clinical practice. In order to assess the role of psychological factors in the development and persistence of pain, a wide array of measures has been developed. Yet there is likely to be considerable conceptual overlap between such measures, and consequently, a lack of clarity about the importance of psychological factors. The aims of this study were to investigate the extent of any such overlap. An observational cohort study of 1591 LBP patients consulting in primary care completed data on a range of psychological instruments. Exploratory and confirmatory factor analyses (EFA and CFA, respectively) were carried out at the subscale level (n=20) to investigate factor structure. The influences of the derived factors on clinical outcomes (pain intensity and self-reported disability) were then tested using linear regression. EFA yielded 4 factors, termed “Pain-related distress,” “Cognitive coping,” “Causal beliefs,” and “Perceptions of the future,” which accounted for 65.5% of the variance. CFA confirmed the validity of these factors models. The pain-related distress factor was found to have the strongest association to LBP patients’ outcomes, accounting for 34.6% of the variance in pain intensity, and 51.1% of the variance in disability. Results confirmed that considerable overlap exists in psychological measures commonly used in LBP research. Most measures tap into patients’ emotional distress. These findings help us to understand how psychological constructs relate together; implications for future research and clinical practice are discussed. [Copyright &y& Elsevier]

Background. The IMPaCT Back study (IMplementation to improve Patient Care through Targeted treatment for Back pain) is a quality improvement study which aims to investigate the effects of introducing and supporting a subgrouping for targeted treatment system for patients with low back pain (LBP) in primary care. This paper details the subgrouping for targeted treatment system and the clinical training and mentoring programmes aimed at equipping clinicians to deliver it.The subgrouping and targeted treatment system. This system differs from ‘one-size fits all’ usual practice as it suggests that first contact health care practitioners should systematically allocate LBP patients to one of the three subgroups according to key modifiable prognostic indicators for chronicity. Patients in each subgroup (those at low, medium or high risk of chronicity) are then managed according to a targeted treatment system of increasing complexity.The subgrouping tools. Subgrouping tools help guide clinical decision-making about treatment and onward referral. Two subgrouping tools have been used in the IMPaCT Back study, a 9-item version used by participating physiotherapists and a 6-item version used by GPs.The targeted treatments. The targeted treatments include a minimal intervention delivered by GPs (for those patients at low risk of poor outcome) or referral to primary care physiotherapists who can apply physiotherapy approaches to addressing pain and disability (for those at medium risk) and additional cognitive-behavioural approaches to help address psychological and social obstacles to recovery (for those at high risk).The training packages. Building on previous interventions for other pilot studies and randomized trials, we have developed and delivered clinical training and support programmes for GPs and physiotherapists.Discussion. This paper describes in detail the IMPaCT Back study’s subgrouping for targeted treatment system and the training and mentoring packages aimed at equipping clinicians to deliver it, within the IMPaCT Back study.Study registration.

The article presents a randomised controlled study which compares the clinical and cost-effectiveness of stratified primary care management for low back pain. The study examined 851 patients who were divided into intervention and control groups. The results show the significant implications of a stratified approach for future primary care management of back pain.

Originally the term "yellow flags" was used to describe psychosocial prognostic factors for the development of disability following the onset of musculoskeletal pain. The identification of yellow flags through early screening was expected to prompt the application of intervention guidelines to achieve secondary prevention. In recent conceptualizations of yellow flags, it has been suggested that their range of applicability should be confined primarily to psychological risk factors to differentiate them from other risk factors, such as social and environmental variables. This article addresses 2 specific questions that arise from this development: (1) Can yellow flags influence outcomes in people with acute or subacute low back pain? and (2) Can yellow flags be targeted in interventions to produce better outcomes? Consistent evidence has been found to support the role of various psychological factors in prognosis, although questions remain about which factors are the most important, both individually and in combination, and how they affect outcomes. Published early interventions have reported mixed results, but, overall, the evidence suggests that targeting yellow flags, particularly when they are at high levels, does seem to lead to more consistently positive results than either ignoring them or providing omnibus interventions to people regardless of psychological risk factors. Psychological risk factors for poor prognosis can be identified clinically and addressed within interventions, but questions remain in relation to issues such as timing, necessary skills, content of treatments, and context. In addition, there is still a need to elucidate mechanisms of change and better integrate this understanding into the broader context of secondary prevention of chronic pain and disability.

Abstract: Many psychological factors have been suggested to be important obstacles to recovery from low back pain, yet most studies focus on a limited number of factors. We compared a more comprehensive range of 20 factors in predicting outcome in primary care. Consecutive patients consulting 8 general practices were eligible to take part in a prospective cohort study; 1591 provided data at baseline and 810 at 6months. Clinical outcome was defined using the Roland and Morris Disability Questionnaire (RMDQ). The relative strength of the baseline psychological measures to predict outcome was investigated using adjusted multiple linear regression techniques. The sample was similar to other primary care cohorts (mean age 44years, 59% women, mean baseline RMDQ 8.6). The 20 factors each accounted for between 0.04% and 33.3% of the variance in baseline RMDQ score. A multivariate model including all 11 scales that were associated with outcome in the univariate analysis accounted for 47.7% of the variance in 6months RMDQ score; rising to 55.8% following adjustment. Four scales remained significantly associated with outcome in the multivariate model explaining 56.6% of the variance: perceptions of personal control, acute/chronic timeline, illness identify and pain self-efficacy. When all independent factors were included, depression, catastrophising and fear avoidance were no longer significant. Thus, a small number of psychological factors are strongly predictive of outcome in primary care low back pain patients. There is clear redundancy in the measurement of psychological factors. These findings should help to focus targeted interventions for back pain in the future. [Copyright &y& Elsevier]

Background A number of factors influence an individual's decision to take sickness absence or to remain at work while ill. The relationship between health, work characteristics, individual perceptions of work and sickness absence and performance is complex and further clarification of the interactions between these factors is necessary.

The article focuses on the importance of Work and Organization Assessment Questionnaire (WOAQ) in evaluating public sector development. It cites the cross-sectional survey which is designed to measure demographics, characteristics and work organizations in the public sector. It demonstrates how WOQA, with the scoring method, develops the manufacturing sector. It claims that WOQA is the most useful and potential transferable tool to examine the work and organization factors in the public sector.

As the experience of stigma and its psychological dimensions require careful measurement, the purpose of this study was to examine the psychometric properties and factor structure of the Feelings of Stigmatization Questionnaire (FSQ). A total of 170 participants with psoriasis and 124 with atopic dermatitis (AD) completed the FSQ. AD participants self-rated AD severity, while psoriasis severity was determined by a clinician. Confirmatory (CFA) and exploratory factor analytic (EFA) techniques were used to examine the factor structure of the FSQ. The FSQ total score was not related to age, age at onset, illness duration or psoriasis severity but it was negatively associated with AD severity ( r = −.25, p < .01). The original six-factor structure of the FSQ was not replicated in our sample. Using EFA, a fixed three-factor solution proved the most stable, with the dimensions of feeling flawed, anticipation of rejection and secrecy, and positive attitudes towards skin disease being identified.

Abstract: Objective: The objective of this study was to examine the psychometric properties and clinical correlates of the 20-item Toronto Alexithymia Scale (TAS-20) in patients with psoriasis. Methods: Three hundred patients with psoriasis completed the TAS-20 and had the severity of their psoriasis clinically assessed. Test–retest reliability was assessed over 10 weeks in a subset of 71 patients receiving standard medical treatment for their psoriasis. Examination of the factor structure employed both exploratory (EFA) and confirmatory (CFA) factor analysis techniques. Results: The overall prevalence of alexithymia in this population of psoriasis patients, as indicated by the TAS-20, was 33%. The TAS-20 total score was not related to clinical severity, age, age at onset or duration of psoriasis. The 10-week test–retest reliability on a sample of 71 psoriasis patients, pre- and posttreatment with photochemotherapy, was found to be acceptable (r=.69; P<.001). EFA produced no stable solutions. The three-factor structure of the TAS-20 using CFA was also not replicable in this sample. Conclusions: The findings of this study support the contention that alexithymia is not significantly influenced by either disease severity or chronicity in patients with psoriasis. It is recommended that when employing the TAS-20 in patients with psoriasis, caution is exercised in the interpretation of the scale scores and that further psychometric evaluation of the scale is undertaken as appropriate.

Information processing biases relate to the manner in which people attend to particular types of information more readily than others. This bias, which is central to cognitive models of disorder, has not been explored in patients with psoriasis. The purpose of this study was to examine whether patients with psoriasis show an automatic attentional bias to classes o fin formation relative to controls. Sixty patients and 60 age- and sex-matched controls completed a computer-based attentional interference task (the modified Stroop task). Patients with psoriasis showed significant interference for disease-specific, self-referent, and others' behavior stimuli relative to controls. In terms of information processing biases, the relationship between subject status (psoriasis patient vs. control) and color-naming interference was significantly stronger than that between anxiety, depression and worry, and interference. Recall bias was limited to disease-specific stimuli only. The observed bias to threat is more appropriately accounted for by participant's status (i.e., psoriasis patient or control) than by psychological distress. [ABSTRACT FROM AUTHOR]

There has been increasing interest in the secondary prevention of chronic pain and pain-associated disability over the past 3 decades. In 2011, psychologically informed practice (PiP) was suggested as a framework for managing persistent and recurrent pain, and, since then, it has underpinned the development of stratified care linking risk identification (screening). Although PiP research trials have demonstrated clinical and economic advantage over usual care, pragmatic studies have been less successful, and qualitative studies have identified implementation difficulties in both system delivery and individual clinical management. Effort has been put into the development of screening tools, the development of training, and the assessment of outcomes; however, the nature of the consultation has remained relatively unexplored. In this Perspective, a review of the nature of clinical consultations and the clinician-patient relationship is followed by reflections on the nature of communication and the outcome of training courses. Consideration is given to the optimization of communication, including the use of standardized patient-reported measures and the role of the therapist in facilitating adaptive behavior change. Several challenges in implementing a PiP approach in day-to-day practice are then considered. Following brief consideration of the impact of recent developments in health care, the Perspective concludes with a brief introduction to the PiP Consultation Roadmap (the subject of a companion paper), the use of which is suggested as a way of structuring the consultation with the flexibility required for a patient-centered approach to guided self-management of chronic pain conditions., (© The Author(s) 2023.

Psychologically informed practice (PiP) includes a special focus on psychosocial obstacles to recovery, but research trials have revealed significant difficulties in implementing PiP outside of research environments. Qualitative studies have identified problems of both competence and confidence in tackling the psychosocial aspects of care, with a tendency to prefer dealing with the more mechanical aspects of care. In PiP, the distinction between assessment and management is not clear-cut. Analysis of the problem is part of the intervention, and guided self-management begins with the initial detective work by the patient, who is encouraged to develop successful and relevant behavior change. This requires a different style and focus of communication that some clinicians find difficult to enact. In this Perspective, the PiP Consultation Roadmap is offered as a guide for clinical implementation to establish a therapeutic relationship, develop patient-centered communication, and guide effective pain self-management. These strategies are illustrated through the metaphor of the patient learning to drive, with the therapist as a driving instructor and the patient as a student driver. For convenience, the Roadmap is depicted in 7 stages. Each stage represents aspects of the clinical consultation in a recommended order, although the Roadmap should be viewed as a general guide with a degree of flexibility to accommodate individual differences and optimize PiP interventions. It is anticipated that the experienced PiP clinician will find it progressively easier to implement the Roadmap as the building blocks and style of consultation become more familiar., (© The Author(s) 2023.

There has been growing interest in psychologically oriented pain management over the past 3 to 4 decades, including a 2011 description of psychologically informed practice (PIP) for low back pain. PIP requires a broader focus than traditional biomechanical and pathology-based approaches that have been traditionally used to manage musculoskeletal pain. A major focus of PIP is addressing the behavioral aspects of pain (ie, peoples' responses to pain) by identifying individual expectations, beliefs, and feelings as prognostic factors for clinical and occupational outcomes indicating progression to chronicity. Since 2011, the interest in PIP seems to be growing, as evidenced by its use in large trials, inclusion in scientific conferences, increasing evidence base, and expansion to other musculoskeletal pain conditions. Primary care physicians and physical therapists have delivered PIP as part of a stratified care approach involving screening and targeting of treatment for people at high risk for continued pain-associated disability. Furthermore, PIP is consistent with recent national priorities emphasizing nonpharmacological pain management options. In this perspective, PIP techniques that range in complexity are described, considerations for implementation in clinical practice are offered, and future directions that will advance the understanding of PIP are outlined.

Objectives: To test whether change in fear-avoidance beliefs was a mediator of the effect of treatment on disability outcome, and to test an analytical approach, latent growth modeling, not often applied to mediation analysis., Methods: Secondary analysis was carried out on a randomized controlled trial designed to compare an intervention addressing fear-avoidance beliefs (n=119) with treatment as usual (n=121) for patients with low back pain, which found the intervention to be effective. Latent growth modelling was used to perform a mediation analysis on the trial data to assess the role of change in fear-avoidance beliefs on disability outcome. The product of coefficients with bias-corrected bootstrapped confidence intervals was used to calculate the mediating effect., Results: A statistically significant mediating effect of fear-avoidance beliefs on the effect of treatment on disability outcome was found (standardized indirect effect -0.35; bias-corrected 95% CI, -0.47 to -0.24). Poor fit of the model to the data suggested that other factors not accounted for in this model are likely to be part of the same mediating pathway., Discussion: Fear-avoidance beliefs were found to mediate the effect of treatment on disability outcome. Measurement of all potential mediator variables in future studies would help to more strongly identify which factors explain observed treatment effects. Latent growth modelling was found to be a useful technique to apply to studies of treatment mediation, suggesting that future studies could use this approach.

Purpose Research of employer policies and practices to manage and prevent disability spans many disciplines and perspectives, and there are many challenges related to stakeholder collaboration, data access, and interventions. The purpose of this article is to synthesize the findings from a conference and year-long collaboration among a group of invited researchers intended to spur new research innovations in this field. Methods A multidisciplinary team of 26 international researchers with published research in employer-based disability management or related fields were invited to attend a 3-day conference in Hopkinton, Massachusetts, USA. The conference goals were to review the status of current research of workplace disability management and prevention, examine its relevance for employer decision-making, compare conceptual frameworks or theoretical perspectives, and recommend future research directions. In this paper, we summarize key points from the 6 resulting papers, compare them with an earlier 2005 conference on improving return-to-work research, and conclude with recommendations for further overarching research directions. Results/Conclusion In comparison with the 2005 conference, a greater emphasis was placed on organizational and social factors, employer roles and responsibilities, methods of implementation, non-clinical approaches, and facilitating stay-at-work as well as return-to-work. A special panel of employer consultants and representatives who were featured at the 2015 conference reinforced the importance of organizational culture, leadership style, and financial decision-making strategies at the employer level. Based on the conference proceedings, we recommend that future research in this area should strive for: (a) broader inclusion of workers and workplaces; (b) attention to multilevel influences in the workplace;, Competing Interests: Chris J. Main and William S. Shaw declare that they have no conflict of interest. Ethical Approval This article does not contain any studies with human participants or animals performed by any of the authors, so there was no need for ethical approval or informed consent. In summarizing overall conclusions of the conference, no personally identifiable or confidential information is shared, and preparation of this manuscript adhered strictly to the research ethics embodied by the Declaration of Helsinki., ((c) a focus on social as well as physical aspects of work; (d) earlier employer collaboration efforts; (e) more attention to implementation factors; and (f) a broader assessment of possible outcome domains.)

Purpose Employer policies and practices have been shown to impact workplace disability, but research in this area has waned in recent years despite an aging workforce, a growing prevalence of chronic health conditions, and a larger proportion of working-age adults on permanent work disability in many jurisdictions. The purpose of this article is to describe the background rationale and methodology for an invited conference designed to improve research of employer strategies to curtail work disability. Methods A multidisciplinary team of 26 international researchers with published research in employer-based disability management or related fields were invited to attend a 3-day conference in Hopkinton, Massachusetts, USA. The overall goal was to review the status of current research of workplace disability management and prevention, examine its relevance for employer decision-making, compare conceptual frameworks or theoretical perspectives, and recommend future research directions. Working groups were organized and draft manuscripts were prepared in advance. Conference activities included working group presentations and critiques, discussions with a panel of industry consultants and advisors, group interaction and debate, generation of final recommendations, and manuscript revision. Results/Conclusion Six principal domains were established with respect to future research: (a) further elucidation of the key workplace factors that buffer the disabling effects of injury and illness; (b) more innovative and feasible options for workplace intervention; (c) measurement of workplace-relevant disability outcomes; (d) a stronger theoretical framework for understanding the factors behind employer uptake and implementation; (e) a focus on special clinical populations and occupations where disability risk is most troubling; and (f) better representation of workers and employers that reflect the diverse and changing nature of work. Final comments and recommendations of the working groups are presented in the following six articles in this special issue of the Journal of Occupational Rehabilitation. Conference attendees recommended changes in methodology, collaboration strategies, and theoretical perspectives to improve the practical and scientific impact of future research of employer practices., Competing Interests: William S. Shaw declares that he has no conflict of interest. Chris J. Main declares that he has no conflict of interest. Michael K. Nicholas declares that he has no conflict of interest. Glenn Pransky declares that he has no conflict of interest. Johannes R. Anema declares that he has no conflict of interest. Steven J. Linton declares that he has no conflict of interest. Ethical Approval This article does not contain any studies with human participants or animals performed by any of the authors, so there was no need for ethical approval or informed consent.

Purpose For work disability research to have an impact on employer policies and practices it is important for such research to acknowledge and incorporate relevant aspects of the workplace. The goal of this article is to summarize recent theoretical and methodological advances in the field of Implementation Science, relate these to research of employer disability management practices, and recommend future research priorities. Methods The authors participated in a year-long collaboration culminating in an invited 3-day conference, "Improving Research of Employer Practices to Prevent Disability", held October 14-16, 2015, in Hopkinton, MA, USA. The collaboration included a topical review of the literature, group conference calls to identify key areas and challenges, drafting of initial documents, review of industry publications, and a conference presentation that included feedback from peer researchers and a question/answer session with a special panel of knowledge experts with direct employer experience. Results A 4-phase implementation model including both outer and inner contexts was adopted as the most appropriate conceptual framework, and aligned well with the set of process evaluation factors described in both the work disability prevention literature and the grey literature. Innovative interventions involving disability risk screening and psychologically-based interventions have been slow to gain traction among employers and insurers. Research recommendations to address this are : (1) to assess organizational culture and readiness for change in addition to individual factors; (2) to conduct process evaluations alongside controlled trials; (3) to analyze decision-making factors among stakeholders; and (4 ) to solicit input from employers and insurers during early phases of study design. Conclusions Future research interventions involving workplace support and involvement to prevent disability may be more feasible for implementation if organizational decision-making factors are imbedded in research designs and interventions are developed to take account of these influences., Competing Interests: Chris J. Main declares that he has no conflict of interest. Michael K. Nicholas declares that he has no conflict of interest. William S. Shaw declares that he has no conflict of interest. Lois E. Tetrick declares that she has no conflict of interest. Mark G. Ehrhart declares that he has no conflict of interest. Glenn Pransky declares that he has no conflict of interest.

The McGill pain questionnaire (MPQ) and its later derivative the short form-MPQ have been used widely both in experimental and clinical pain studies. They have been of considerable importance in stimulating research into the perception of pain and now, with the publication of its latest variant, the short form-MPQ-2, it is appropriate to appraise their utility in the light of subsequent research into the nature of pain and the purpose of pain assessment. Following a description of the content and development of the questionnaires, issues of validity, reliability, and utility are addressed, not only in terms of the individual pain descriptors and the scales, but also in terms of methods of quantification. In addition, other methods of pain depiction are considered. In the second part of the review, advances in pain measurement and methodology, in the elucidation of pain mechanisms and pathways, in the psychology of pain, and in the nature of pain behavior are presented and their implications for pain assessment in general and the MPQ family of measures in particular will be addressed. It is suggested that pain assessment needs to be cast in its social context. We need to understand the influences on pain expression using a socio-communication model of pain that recognizes the function of pain and the importance of both innate pain responses and the effects of social learning. The review concludes with recommendations for future use of the MPQ and identifies a number of research challenges which lie ahead.

Background: A considerable proportion of work absence is attributed to back pain, however prospective studies in working populations with back pain are variable in setting and design, and a quantitative summary of current evidence is lacking., Objective: To investigate the extent to which differences in setting, country, sampling procedures and methods for data collection are responsible for variation in estimates of work absence and return to work., Methods: Systematic searches of seven bibliographic databases. Inclusion criteria were: adults in paid employment, with back pain, work absence or return to work during follow-up had been reported. Random effects meta-analysis and meta-regression analysis was carried out to provide summary estimates of work absence and return to work rates., Results: 45 studies were identified for inclusion in the review; 34 were included in the meta-analysis. The pooled estimate for the occurrence of work absence in workers with back pain was 15.5% (95% CI 9.8% to 23.6%, n=17 studies, I(2) 98.1%) in studies with follow-up periods of ≤6 months. The pooled estimate for the proportion of people with back pain returning to work was 68.2% (95% CI 54.8% to 79.1%, n=13, I(2) 99.2%), 85.6% (95% CI 78.2% to 90.7%, n=13, I(2) 98.7%) and 93.3% (95% CI 84.0% to 94.7%, n=10, I(2) 99%), at 1 month, 1-6 months and ≥6 months, respectively. Differences in setting, risk of participation bias and method of assessing work absence explained some of the heterogeneity., Conclusions: Pooled estimates suggest high return to work rates, with wide variation in estimates of return to work only partly explained by a priori defined study-level variables. The estimated 32% not back at work at 1 month are at a crucial point for intervention to prevent long term work absence.

Introduction: Common health problems have a significant impact on work productivity (presenteeism), and sickness absence. The aim of this study was to examine the attitudes and beliefs of employees in the public sector about common health problems and work using the Flags system as a conceptual framework to identify problems and potential solutions., Method: 63 employees took part in 14 focus groups in two public sector organisations. Discussions were audio-recorded, transcribed, and analysed thematically using NVivo., Results: The study confirmed the importance of heath-focused clinical factors (Yellow flags), perceptions of work (Blue flags), and more objective characteristics of work and organisational policies (Black flags), which emerged as major themes. The social and moral norms surrounding sickness absence and presenteeism were frequently discussed, including the impact of absence on colleagues, guilt, legitimising illness, and trust. There were interactions between the different Flags, often mediated by managers via their relationships with employees and their role in implementing organisational policy., Conclusions: The Flags system was useful as a conceptual framework in this context for identifying a number of obstacles to working with health problems, many of which were potentially modifiable on worker, workplace, or wider systems levels.

There is mounting evidence that occupational factors influence the extent of sickness absence following an episode of low back pain, but there have been limited efforts to integrate the identification and management of occupational factors into the routine practice of physical therapists. Systematic reviews suggest that a client's report of heavy physical demands, inability to modify job tasks, work stress, lack of organizational support, job dissatisfaction, poor expectations for resuming usual work, and fear of reinjury are indications of significant barriers to returning to work. Recommended strategies for evaluating and addressing occupational factors are explored with respect to the physical therapist's role in client assessment, development of activity and lifestyle recommendations, therapeutic exercise, communication with other providers, and summary reports. Primary recommendations include: (1) administration of self-report questionnaires to assess a client's perspective of physical job demands, (2) client-centered interviewing to highlight individual return-to-work concerns, (3) early discussions with clients about possible job modifications, and (4) incorporation of clients' workplace concerns in progress reports and summaries. These strategies may improve low back pain outcomes by encouraging effective communication with key stakeholders and by developing clients' ability to resolve obstacles to returning to work.

In this perspective article, a number of conclusions and recommendations are offered based on the articles in this special issue of PTJ. In this special issue, a new approach to physical therapy, termed "psychologically informed practice," is offered as a "middle way" between narrowly focused standard physical therapist practice based on biomedical principles and the more cognitive-behavioral approaches developed originally for the treatment of mental illness. This new approach uses the "flags" framework, with psychologically informed practice requiring routine and specific consideration of "yellow flags" and "blue flags" (depending on clinical setting) for determining risk of poor outcome and identifying the potential for treatment modification-but with cognizance of the overall environment or context in which the clinician must operate. This context includes professional culture, health care policy, and insurance reimbursement (potential "black flags"). The primary goal of this approach is to prevent the development of unnecessary pain-associated activity limitations. The approach is based on the identification of normal psychological processes that affect the perception of pain and the response to it as an expected and normal part of the musculoskeletal pain experience and that are potentially modifiable. The potential for linking risk identification with targeted treatment has been discussed, this article focuses on the potential implications for training and implementation, drawing on experience in developing training programs in which the trainees have welcomed this new approach, viewing it as a helpful extension of their basic professional training. Indeed, this new approach can be viewed as evolutionary rather than revolutionary, in that it builds upon the established professional expertise of physical therapists, but incorporates systematic attention to the psychosocial factors that are associated with outcome of treatment.

Introduction: Musculoskeletal complaints can impact on work in terms of productivity, sickness absence and long term incapacity for work. While employee attitudes and knowledge can drive absenteeism and presenteeism behaviour, managers also play an important role in influencing this via the quality of their relationships with employees and their role in implementing organisational policies and procedures. The aims of this study were to investigate the beliefs and attitudes of managers and employees with musculoskeletal pain about sickness absence, presenteeism, and return to work and to identify areas of consensus and conflict., Methods: 18 employees with musculoskeletal pain and 20 managers from two large public sector organisations in South Wales, UK, took part in individual face-to-face interviews. Data were analysed thematically using NVivo., Results: Employees' and managers' reports indicated that there was a strong culture of presenteeism in these organisations. Establishing the legitimacy of complaints was a salient theme for both managers and employees, although their views were in conflict. Employees reported feeling that contact with employers was intrusive when sickness absence was legitimate. Managers were supportive of those who they felt were 'genuinely' unwell, but also cited examples of people 'working the system' and not reporting absences appropriately., Conclusions: These issues require careful consideration of the rights and responsibilities of both employees and employers, where strategies for improving communication, trust, and creating an environment conducive to successful return to work need to be investigated.
