In an attempt to explain how and why some individuals with musculoskeletal pain develop a chronic pain syndrome, Lethem et al. (Lethem J, Slade PD, Troup JDG, Bentley G. Outline of fear-avoidance model of exaggerated pain perceptions. Behav Res Ther 1983; 21: 401-408).ntroduced a so-called 'fear-avoidance' model. The central concept of their model is fear(More)
The authors argued that emotions characterized by certainty appraisals promote heuristic processing, whereas emotions characterized by uncertainty appraisals result in systematic processing. The 1st experiment demonstrated that the certainty associated with an emotion affects the certainty experienced in subsequent situations. The next 3 experiments(More)
Research studies focusing on the fear-avoidance model have expanded considerably since the review by Vlaeyen and Linton (Vlaeyen J. W. S. & Linton, S. J. (2000). Fear-avoidance and its consequences in chronic musculoskeletal pain: a state of the art. Pain, 85(3), 317--332). The fear-avoidance model is a cognitive-behavioral account that explains why a(More)
Abstract Fear-avoidance beliefs and catastrophizing have been implicated in chronic pain and theoretical models have been developed that feature these factor in the transition from acute to chronic pain. However, little has been done to determine whether these factors occur in the general population or whether they arc associated with the inception of an(More)
OBJECTIVES The aim of this study was to investigate the one-year development of self-reported sleep problems in workers with no sleep problem at baseline, and to evaluate the role of work stress in the etiology of a new episode. DESIGN A prospective design was employed. METHODS A total of 816 employees with no sleeping problems during the past three(More)
Given the demand for interventions that may prevent the development of persistent musculoskeletal pain problems, we investigated the effects of a cognitive-behavioral program in a group of non-patients with neck or back pain symptoms. Two hundred and fifty-three people selected from a population study were invited to participate. These people had(More)
OBJECTIVES To establish whether review articles provide consistent conclusions on associations between workplace psychosocial factors and musculoskeletal pain and, if differences exist, to explore whether this is related to the methods used. METHODS Reviews, reported up to February 2007, that included consideration of workplace psychosocial factors and(More)
Operant conditioning of pain reports was studied in two laboratory experiments. In the first one 5 subjects were given the same pain stimulus on 15 trials and their recorded pain ratings gave no systemic trends across subjects. 8 other subjects received the same pain tests but on some of the trials increases or decreases in pain ratings were verbally(More)
