Pain-related fear predicts disability, but not pain severity: a path analytic approach of the fear-avoidance model.

Two studies are reported that tested the fear-avoidance (FA) model using path analytic techniques. In study 1, 429 employees with back pain at baseline and back pain at 18 months follow-up completed questionnaires assessing sociodemographic information, pain severity, negative affect, pain-related fear, and disability. Results indicated that pain severity at baseline predicted pain-related fear and disability at follow-up, and that pain-related fear is rather a consequence than an antecedent of pain severity.

Self-discrepancies in work-related upper extremity pain: relation to emotions and flexible-goal adjustment.

Recurrent pain not only has an impact on disability, but on the long term it may become a threat to one's sense of self. This paper presents a cross-sectional study of patients with work-related upper extremity pain and focuses on: (1) the role of self-discrepancies in this group, (2) the associations between self-discrepancies, pain, emotions and (3) the interaction between self-discrepancies and flexible-goal adjustment. Eighty-nine participants completed standardized self-report measures of pain intensity, pain duration, anxiety, depression and flexible-goal adjustment.

A content analysis of ideal, ought, and feared selves in patients with chronic low back pain.

Patients with chronic pain are not only faced with disabilities but are also challenged to maintain a valued sense of self. This sense of self is in part determined by the extent to which patients can accomplish their identity-related goals. The present study explores the content of three domains of the self, namely the ideal, ought and feared self and examines how the content relates to disability and depression.

Dimensional and componential structure of a hierarchical organization of pain-related anxiety constructs.

Research has identified several anxiety and fear constructs that contribute directly or indirectly to the chronic course of pain. One way to gain insight into the frequently observed interrelations between these constructs may be by conceptualizing them within a hierarchical structure. In this structure, general and specific constructs are proposed at different levels of a hierarchical tree.

Active avoidance but not activity pacing is associated with disability in fibromyalgia.

Activity pacing has been suggested as a behavioural strategy that may protect patients with fibromyalgia (FM) against activity dysregulation and disability. The aim of the present study was to empirically test whether the construct of activity pacing is distinct from other behavioural strategies assessed with the Chronic Pain Coping Inventory (CPCI), such as guarding, resting, asking for assistance, relaxation, task persistence, exercise/stretch, seeking social support, and coping self-statements. The second objective was to test whether pacing was associated with physical disability when controlling for pain catastrophizing, pain severity and the other behavioural strategies as measured with CPCI.

Treatments addressing pain-related fear and anxiety in patients with chronic musculoskeletal pain: a preliminary review.

This review covers the current cognitive behavioural treatments available to address fear-avoidance beliefs in patients with chronic musculoskeletal pain (CMP). Four types of treatment protocols were identified for inclusion in the review: (a) graded in vivo exposure (GivE); (b) graded activity (GA); (c) acceptance and commitment therapy (ACT); and (d) mixed cognitive behavioural protocols. Most of the research suggests that GivE and ACT result in the best outcomes for treating fear-avoidance beliefs in patients with CMP.

The role of current mood and stop rules on physical task performance: an experimental investigation in patients with work-related upper extremity pain.

Patients with work-related upper extremity pain (WRUED) experience disability in daily life activities. The factors that influence levels of disability are still unclear. Both excessive avoidance and persistence have been suggested, but the affective and motivational processes that underlie these behaviours have not been scrutinized.

Falls and catastrophic thoughts about falls predict mobility restriction in community-dwelling older people: A structural equation modelling approach.

Objectives: How and when concerns about falls emerge is not yet completely known, because these concerns are present in both people with and without a falls history. The aim of this study was to investigate the role of catastrophic beliefs about falls and previous falls in the development of concerns about falls and resulting mobility restrictions (MR).

Method: Within a cross-sectional design, 896 older people (mean age 76.

Threat of pain influences social context effects on verbal pain report and facial expression.

Current theoretical models of pain catastrophizing have diverging predictions regarding the role of social context and perceived threat on pain expression. The communal coping model of catastrophizing predicts that high pain catastrophizers display more pain expression in the presence of another, regardless of the threat value of the pain, while a cognitive appraisal model predicts high pain catastrophizers to express more pain when pain has increased threat value, regardless of social context. A 2 x 2 factorial design was used to test the validity of both predictions.

Cost-effectiveness of multidisciplinary management of Tinnitus at a specialized Tinnitus centre.

Background: Tinnitus is a common chronic health condition that affects 10% to 20% of the general population. Among severe sufferers it causes disability in various areas. As a result of the tinnitus, quality of life is often impaired.

The psychology of fatigue in patients with multiple sclerosis: a review.

Fatigue is a frequent and disabling symptom in patients with multiple sclerosis (MS), but it is difficult to define and measure. Today, MS-related fatigue is not fully understood, and evidence related to explanatory pathophysiological factors are conflicting. Here, we evaluate the contribution of psychological factors to MS-related fatigue.

Reduction of pain-related fear and disability in post-traumatic neck pain: a replicated single-case experimental study of exposure in vivo.

Unlabelled: For patients with acute post-traumatic neck pain (PTNP), pain-related fear has been identified as a potential predictor of chronic disability. If such is the case, fear reduction should enhance the prevention of further pain disability and distress after traumatic neck pain disability. However, exposure-based treatments have not been tested in patients with PTNP.

The fidelity of treatment delivery can be assessed in treatment outcome studies: a successful illustration from behavioral medicine.

Objectives: Treatment outcome studies ought to assess the fidelity of their treatments, including treatment delivery, but practical guidelines and examples for this are lacking. Based on general recommendations in available literature, this study proposes and illustrates the design and application of a Method of Assessing Treatment Delivery (MATD) in a behavioral medicine trial comparing two treatments for chronic low back pain.

Study Design And Setting: In designing MATD, two experts identified several feasible treatment elements.

The influence of fear of movement and pain catastrophizing on daily pain and disability in individuals with acute whiplash injury: a daily diary study.

Previous research supports the fear-avoidance model in explaining the transition from acute to chronic non-specific musculoskeletal pain. However, there is still little knowledge on when this vicious circle of pain, disability, pain catastrophizing and fear of movement starts. We performed a daily diary study in 42 patients with acute whiplash injury.

General practitioners' treatment orientations towards low back pain: influence on treatment behaviour and patient outcome.

Background: In low back pain (LBP) treatment and research attention has shifted from a biomedical towards a biopsychosocial approach. Patients' LBP beliefs and attitudes were found to predict long-term outcome, and recently it has been suggested that the health care providers' ideas about LBP are also important predictors of treatment behaviour and outcome.

Aims: In the present study we examined whether (1) differences in General Practitioners' (GP) LBP treatment orientation are associated with differences in actual treatment behaviour and (2) whether treatment orientation is related to LBP outcome in patients.

Long-term effectiveness and costs of a brief self-management intervention in women with pregnancy-related low back pain after delivery.

Background: Pregnancy-related low back pain is considered an important health problem and potentially leads to long-lasting pain and disability. Investigators draw particular attention to biomedical factors but there is growing evidence that psychosocial and social factors might be important. It prompted us to start a large cohort study (n = 7526) during pregnancy until one year after delivery and a nested randomized controlled intervention study in the Netherlands.

More is not always better: cost-effectiveness analysis of combined, single behavioral and single physical rehabilitation programs for chronic low back pain.

Several treatment principles for the reduction of chronic low back pain associated disability have been postulated. To examine whether a combination of a physical training and operant-behavioral graded activity with problem solving training is cost-effective compared to either alone one year post-treatment, a full economic analysis alongside a randomized controlled trial was conducted. In total 172 patients with chronic disabling non-specific low back pain referred for rehabilitation treatment, were randomized to 10 weeks of aerobic training and muscle strengthening of back extensors (active physical treatment; APT), 10 weeks of gradual assumption of patient relevant activities based on operant-behavioral principles and problem solving training (graded activity plus problem solving training; GAP), or APT combined with GAP (combination treatment; CT).

Treatment expectancy and credibility are associated with the outcome of both physical and cognitive-behavioral treatment in chronic low back pain.

Introduction: Patients' initial beliefs about the success of a given pain treatment are shown to affect final treatment outcome. The Credibility/Expectancy Questionnaire (CEQ) has recently been developed as measure of treatment credibility and expectancy.

Objective: The objectives of this study were (1) to investigate the factor structure of the CEQ in a sample of chronic low back pain (CLBP) patients by means of a confirmatory factor analysis, (2) to examine the association between treatment credibility and expectancy and patient characteristics, and (3) to assess whether treatment expectancy and credibility are associated with the outcome of rehabilitation treatment.

Exposure in vivo versus operant graded activity in chronic low back pain patients: results of a randomized controlled trial.

Since pain-related fear may contribute to the development and maintenance of chronic low back pain (CLBP), an exposure in vivo treatment (EXP) was developed for CLBP patients. We examined the effectiveness as well as specific mediating mechanisms of EXP versus operant graded activity (GA) directly and 6 months post-treatment in a multi-centre randomized controlled trial. In total, 85 patients suffering from disabling non-specific CLBP reporting at least moderate pain-related fear were randomly allocated to EXP or GA.
