This research investigated the role of coping strategies in reducing the pain experience of rheumatoid arthritis (RA) patients over a seven-day period. Sixty-three patients completed a twice-daily structured dairy consisting of an eight scale revision of the Ways of Coping (WOC), the depression subscale of the Affects Balance Scale (ABS), and a pain visual analogue scale (VAS). Multivariate analyses for repeated measures identified two coping strategies, Self-Care and Positive Reappraisal, as significantly effective in pain reduction. Self-Care includes behavioral attempts to manage the symptoms of RA. Positive Reappraisal involves cognitive efforts to redefine pain experience in positive terms. The other six coping strategies also demonstrated a trend to increased use on days when pain decreased. These data imply that intraindividual approaches in examining the coping/pain association have potential benefit for determining a causal relation between coping and pain. / Medicine, Faculty of / Cellular and Physiological Sciences, Department of / Graduate

BACKGROUND: Pain intensity, functional status and beliefs and attitudes towards pain are dynamic elements involved in the experience of chronic pain. Lidocaine infusion (LI) is a therapeutic intervention used to relieve pain. OBJECTIVES: The primary objective of this study was to determine if people with chronic pain who received LI and reported a decrease in pain intensity at 4 days post-infusion differed from those who did not report a decrease in pain intensity with respect to the following: a) baseline beliefs and attitudes towards pain; b) changes in belief and attitudes towards pain; c) and changes in functional status. This study also investigated if these differences were associated with being a novel or repeat LI user. A secondary objective was to estimate the sample size required for a larger study. METHODS: This project was an exploratory study. Thirty-three subjects were monitored for pain intensity using the Visual Analogue Scale (VAS) just before the infusion, and then at four days, two weeks, and three weeks after the infusion. The subjects were separated into groups depending on the criteria of whether or not they had: a) criterion-based pain intensity decrease or not on the fourth day post infusion, and b) received a previous LI or not. Since no subjects who received their first LI reported pain intensity decrease four days later, three groups emerged from this classification: first time LI users with no pain decrease, repeat LI users with no pain decrease, and repeat LI users with pain decrease. The subjects completed two self-administered questionnaires the Survey of Pain Attitudes (SOPA-32) and the Short Musculoskeletal Function Assessment (SMFA) - before the infusion, and at two and three weeks post-infusion. The most important change at two or three weeks post-infusion was used for comparison purposes. RESULTS: No significant changes in function (SMFA) were found. However, changes in specific beliefs and attitudes towards pain (SOPA-32) were associated with the group variable as follows: 1) All three groups showed a significantly stronger belief that 'others, especially family members, should be solicitous in response to their experience of pain' after the infusion. 2) Those who received their first LI and did not report pain intensity decrease also showed a significantly stronger belief that 'medications are an appropriate treatment for chronic pain' after the infusion. 3) Subjects who had previous LI and did not report pain intensity decrease were the only ones to believe significantly less that 'medications are an appropriate treatment for chronic pain' and more 'in a medical cure for their pain problem' after the infusion. 4) Subjects who had previous LI and did report pain intensity decrease had a significantly stronger belief in the appropriateness of medications and that 'that they should avoid exercise' after the infusion. 5) Finally, subjects who believed more that 'medications are an appropriate treatment for chronic pain' and less 'that they should avoid exercise' at baseline, had significantly higher chances of experiencing decrease in pain intensity 4 days after a LI. CONCLUSION: The impact of a LI on the individuals' beliefs and attitudes towards pain differs depending if their pain intensity decreased or not four days after the infusion, and if they had previous LI or not. By contrast, their pre-infusion beliefs and attitudes profile impacts on the efficacy of this intervention. Because of the small sample size, the heterogeneity of the subjects in terms of the localization of their pain, and our choice of measurement tool, it is not possible to determine if LI impacts on function. Nevertheless, this exploratory study generated some novel observations and questions that are of great interest for future research. A particular question of interest would be to determine if repeated LI fosters a more passive attitude towards pain management. It was also determined that a sample size of 70 subjects per group would be necessary for future research on this question. / Keywords: Chronic pain, lidocaine, beliefs and attitudes towards pain, function, pain intensity.

This dissertation presents three experiments designed to demonstrate the effects of cognitive, emotional and psychosocial factors on pain perception in humans and to identify potential neuroanatomical substrates of attentional and emotional pain modulation. / The first two chapters provide an introduction, including the statement of the rationale and objectives of this Ph.D. project (Chapter 1) and an overview of the relevant background literature (Chapter 2). / Chapter 3 presents a voxel-based morphometry study on the neural correlates of attentional and emotional pain modulation. In agreement with the observation that manipulations of emotion and attention differentially affect pain perception, the results of this experiment suggest that separate neuroanatomical substrates may underlie these pain modulations: the right lateral orbitofrontal, left medial prefrontal, and bilateral entorhinal cortices appear to be implicated in emotional pain modulation, while the right putamen appears to be involved in attentional pain modulation. / The study described in Chapter 4 shows that the experimental manipulation of mood using emotionally-laden visual stimuli preferentially alters pain unpleasantness, leaving pain intensity unaffected. This study replicates the psychophysical observations presented in the study of Chapter 3 (and in previous reports), which used odors to manipulate emotional state, therefore suggesting the independence of this phenomenon from the mood induction technique employed. / The study in Chapter 5 shows that empathy has an effect on pain perception as well, which cannot be explained by mood effects. Participants for whom a state of high empathy was evoked rated painful stimuli applied to themselves as more intense and unpleasant than did those in a state of low empathy; furthermore, the state empathy ratings correlated with the pain ratings. / By showing that emotional state, attention and empathy can influence pain perception, the work in this thesis provides evidence demonstrating that the pain experience can be significantly molded by top-down factors, and is therefore far from being solely determined by the physical properties of the noxious stimulation. These observations might partially explain why the pain response in certain situations appears disproportionately large, or surprisingly small, in relation to the noxious stimulation, and support the utility of psychological methods in the management of pain symptoms.
