Self-Efficacy and Affect as Mediators Between Pain Dimensions and Emotional Symptoms and Functional Limitation in Women With Fibromyalgia

Promoting walking as a self-care strategy in women with fibromyalgia: a cross‑sectional study using accelerometers

INTRODUCTION

Walking is a beneficial healthy lifestyle for fibromyalgia patients as it reduces the intensity of pain and fatigue experienced and improves quality of life. In this context, self-efficacy and commitment are potential predictors of walking for women with fibromyalgia. Present study aims at examining the moderation role of exercise commitment in the association between self-efficacy for walking and walking behavior in this population.

METHOD

It is a cross‑sectional study. A total of 132 women with fibromyalgia participated (mean age = 57.63, SD = 10.44) between January and December 2018. Self-efficacy about walking was assessed through Spanish version of self-efficacy scale for physical activity scale (SEPAS) and exercise commitment through ad-hoc questionnaire (two Likert-type items about the committed action of physical activity). Walking behavior was measured using accelerometers for seven consecutive days. Pain and fatigue prior to placement of the accelerometer were evaluated as possible covariates. Regarding medical history, time since onset of symptoms (i.e. pain, fatigue) and since diagnosis, and medication were also assessed as possible covariates.

RESULTS

A moderation effect of exercise commitment was found in the relationship between self-efficacy on walking behavior (B = 10.48, p = .021, 95%, CI = 0.61 to 6.79). Post-hoc analyses showed a significant and positive relationship between self-efficacy and walking only with high commitment to physical activity (t = 10.08, p = .027, 95%, CI = 3.77 to 5.64).

CONCLUSIONS

Self-efficacy for walking and commitment should be assessed and potentially targeted when focusing on increasing walking in women with fibromyalgia. Key Points • Associations between walking self-efficacy and exercise engagement provide indications of modifiable targets for promoting an active lifestyle in fibromyalgia. • When patients feel engaged in their physical exercise pattern (walking), patients feel more able to perform the behavior. • Rehabilitation interventions, focused on chronic pain, should contemplate the promotion of self-efficacy and engagement.

A secondary analysis of three types of social support in relation to self-efficacy, disease impact, and depression in fibromyalgia

OBJECTIVE

Fibromyalgia (FM) is a chronic pain condition associated with depression. However, self-efficacy (belief in own ability to manage symptoms) and social support may be protective. This study tested three types of social support (emotional, tangible, and instrumental) for moderation of the mediating effect of self-efficacy on the relationship between FM impact and depression over time.

METHODS

Six hundred participants with FM were randomly assigned to no intervention, social support group, or combined self-management and social support. The Fibromyalgia Impact Questionnaire, Norbeck Social Support Questionnaire, FM-modified Arthritis Self-Efficacy Scale, and Center for Epidemiological Studies-Depression surveys were administered at baseline, 6, 12, and 18 months. There were no significant intervention effects on the variables of interest, however, participants' scores were used to assess four longitudinal models.

RESULTS

Self-efficacy showed mediation both between (b = 0.104, p < .001, 95% CI = [0.071, 0.137]) and within (b = 0.89, p < .001, 95% CI = [0.073, 0.106]) individuals. Only tangible support demonstrated moderation of the relationship between FM impact and self-efficacy, and only between individuals (b = 0.154, p = .022, 95% CI = [0.022, 0.287]).

CONCLUSION

The results indicated that self-efficacy attenuated a portion of the effect of FM impact on depression over time. Additionally, higher levels of tangible support (the belief that your social network can provide you with assistance) were related to weaker influence of FM impact on self-efficacy over time. These factors may be important targets for the prevention of depression in people with FM.

How to Generate Self-Efficacy despite Pain: The Role of Catastrophizing and Avoidance in Women with Fibromyalgia

BACKGROUND AND OBJECTIVE

Fibromyalgia-related pain is influenced by numerous factors, including severity, as well as cognitive profiles based on pain catastrophizing or activity patterns. In this context, self-efficacy is identified as a potential predictor for explaining certain health outcomes. This study aimed to contribute to exploring the role of pain avoidance (as activity pattern) between pain severity and self-efficacy along pain catastrophizing.

METHODS

Through a cross-sectional study, a total of 264 women with fibromyalgia completed self-report measures of pain severity, pain avoidance, pain catastrophizing, and self-efficacy. The severity of the symptoms, the time elapsed since diagnosis, and the time elapsed since the onsets of symptoms were included as covariates to control. Regression-based moderated-mediation analysis was used to test the conditional effect of pain severity on self-efficacy via pain avoidance at varying levels of pain catastrophizing.

RESULTS

Pain avoidance mediated the effect of pain severity on self-efficacy. The indirect effects showed a moderated effect when patients scored high on the pain catastrophizing scale. The model evaluated, where catastrophic pain moderates the indirect effect of pain intensity on self-efficacy through pain avoidance, explained 49% of the variance.

CONCLUSIONS

Catastrophic beliefs associated with pain as being uncontrollable increase the relationship between pain severity and pain avoidance. In turn, pain avoidance is associated with a low perception of capacity.

Pain Catastrophizing as a Mediator Between Pain Self-Efficacy and Disease Severity in Patients with Fibromyalgia

BACKGROUND

Fibromyalgia (FM) is characterized by chronic widespread pain, fatigue, sleep disturbances, cognitive impairment, and mood disturbance. Both pain catastrophizing and pain self-efficacy have been found to be mediators of pain treatment effectiveness. However, whether pain catastrophizing mediates the association between pain self-efficacy and FM severity remains unclear.

AIM

To examine whether pain catastrophizing mediates the association between pain self-efficacy and disease severity in patients with FM.

METHODS

This cross-sectional study included the baseline data of 105 people with FM from a randomized controlled trial. Hierarchical linear regression analysis was performed to examine the predictive ability of pain catastrophizing for FM severity. Furthermore, we examined the mediating effect of pain catastrophizing on the association between pain self-efficacy and FM severity.

RESULTS

Pain self-efficacy was negatively associated with pain catastrophizing (β = -.4043, p < .001). FM severity was positively associated with pain catastrophizing (β = .8290, p < .001) and negatively associated with pain self-efficacy (β = -.3486, p = .014). Pain self-efficacy had a direct effect on FM severity (β = -.6837, p < .001) and an indirect effect on FM severity through the effect of pain catastrophizing (β = -.3352, 95% CI bootstrapping -.5008 to -.1858).

CONCLUSION

Pain catastrophizing independently predicts FM severity and mediates the association between pain self-efficacy and FM severity. Pain catastrophizing should be monitored through interventions aimed at improving pain self-efficacy to reduce symptom burden in patients with FM.

Revealing the Role of Social Support on Cognitive Deficits in Fibromyalgia Syndrome

Despite the relevance of cognitive deficits in fibromyalgia syndrome (FMS) and the attempts to elucidate the influence of the disorder symptoms in the cognitive decline reported by patients, no studies have explored the specific role of social support on cognition in FMS. Social support has been shown to be an essential modulator factor on cognitive performance in other diseases. Sixty-four women with FMS and 32 healthy women participated in the study and completed questionnaires pertaining to anxiety, depression, fatigue, insomnia, clinical pain, and social support, along with a neuropsychological battery assessing verbal memory, organization, strategic and planning abilities, self-regulation, processing speed, attention, and cognitive flexibility. Results showed that FMS patients exhibited lower values in all social support dimensions in comparison with healthy individuals, especially in the socializing dimension. Despite the lower social support observed in FMS, all social support dimensions showed a positive impact on verbal memory, organization and planning abilities, strategic planning, self-regulation, processing speed, attention, and cognitive flexibility in these patients. In fact, social support was associated with greater correct responses and processing speed and minor number of errors in all the neuropsychological battery tests. Socializing was the main predictor of organization and planning abilities, strategic planning, and self-regulation. In sum, results suggest that social support may be a key factor in buffering the cognitive decline observed in FMS. Designing psychoeducation programs and intervention programs directed not only to FMS patients but also relatives, health care workers, and the general population might be essential to improve the social support of FMS patients and positively impact on patient's cognitive status.

Understanding the Associations across Fibromyalgia-Related Fatigue, Depression, Anxiety, Self-Esteem Satisfaction with Life and Physical Activity in Portuguese and Brazilian Patients: A Structural Equation Modeling Analysis

Background and Objectives: Fibromyalgia are heterogeneous and differ from patient to patient; however, the most reported are general myalgia and at specific points associated with fatigue and certain psychological adversities. Physical activity can mitigate the effects of the symptoms. However, the associations between fibromyalgia-related fatigue, self-esteem, anxiety, depression, satisfaction with life and physical activity are unclear. Therefore, the aim of the present study was to understand the associations between these symptoms and whether there are differences between these associations across two distinct cultures. Materials and Methods: A total of 473 women aged between 28 and 75 years (M = 49.27; SD ± 8.28) completed five questionnaires about fibromyalgia-related fatigue, physical activity, anxiety, depression, self-esteem, and satisfaction with life. Results: Fibromyalgia-related fatigue was positively associated with depression and anxiety, depression and anxiety were negatively associated with self-esteem, self-esteem was positively associated with satisfaction with life, satisfaction with life was positively associated with physical activity and there were no differences in terms of the perceptions and associations of these variables between Portuguese and Brazilian patients. Conclusions: Our results showed the significant role of associations between these variables and a similarity in the perception and relationship of the variables between the two cultures.

Total Pain and Illness Acceptance in Pelvic Cancer Patients: Exploring Self-Efficacy and Stress in a Moderated Mediation Model

Cancer patients experience pain not only in its physical dimension, but also in a broader context that includes psychological, social, and spiritual aspects due to a higher level of anxiety and stress. The present prospective, longitudinal study examined the relationship between total pain and illness acceptance among pelvic cancer patients, taking into consideration the moderated mediation effects of self-efficacy and stress. The study involved a sample of pelvic cancer patients receiving radiotherapy treatment. Assessments were completed at T1 (before radiotherapy), T2 (after 3-4 weeks), and T3 (after radiotherapy) to assess the psychosocial dynamics of illness acceptance (N = 267). The more physical, psychological, social, and spiritual pain symptoms the patients experienced, the less they accepted negative health conditions and the effects of their illness. Stress moderated the indirect effect between total pain dimensions and illness acceptance through self-efficacy, but it did not moderate the relationship between total pain and illness acceptance. The relationships between total pain dimensions and illness acceptance thus depend on both the mediating effect of self-efficacy and the moderating effect of stress. This highlights the need to control one's motivation and behavior and manage emotional strain or tension.

Behavioral Medicine Physiotherapy in the Context of Return to Work for Chronic Pain: A Single-Case Experimental Design Study

Effective interventions are needed for return-to-work (RTW) for individuals with chronic pain on long-term sick leave. In this study, a behavioral medicine physiotherapy protocol was systematically replicated and added to workplace components. The intervention was evaluated for fidelity and effects on target activities and work ability. A single-case experimental design was used with five participants. Daily and weekly ratings of personalized target activities at work as well as work ability were carried out throughout the study period of 26–28 weeks. Effects of the behavioral medicine physiotherapy intervention were evaluated for each individual using visual analysis of displayed graphs and quantitative non-overlap methods. Goal achievement for target activities was reviewed. Three participants completed the intervention. The results indicated an effect from the behavioral medicine physiotherapy intervention on task-specific self-efficacy for target activities, but no consistent effect on experience of target activities or work ability. All three participants had increased function in target activities in line with pre-defined goals. Fidelity to the intervention manual was good. Behavioral medicine physiotherapy can be successfully adapted to work disability and was here replicated in an RTW context for individuals with chronic pain. The intervention protocol should be further evaluated in large-scale studies.

Metacognitions on Pain, Functionality and Intensity of Pain in Women with Fibromyalgia

To determine the explanatory capacity of pain metacognitions and beliefs over the functionality, coping and pain intensity, following the Model of Self-Regulatory Executive Functions (S-REF) in a sample of women with fibromyalgia from Medellín and its Metropolitan Area. Method: Metacognitions Scale on Symptom Control, Pain Self-efficacy Questionnaire, Chronic Pain Catastrophizing Scale, Chronic Pain Coping Questionnaire, WHODAS 2.0 Scale, and Pain Intensity Numerical Scale. The sample was represented by 108 women between 24 and 60 years old with a diagnosis of fibromyalgia. A modeling process was carried out through an analysis of structural equations. Results: The final model fails to fit. Despite this, the analysis suggests that negative metacognitions and pain self-efficacy have an effect over the tendency to catastrophizing. The latter and the pain self-efficacy are the main mediators in the effects of functionality. The intensity of pain is not determined by the metacognitions related to it.

The Role of Positive Psychological Factors in the Association between Pain Intensity and Pain Interference in Individuals with Chronic Musculoskeletal Pain: A Cross-Sectional Study

This study aimed to test the cross-sectional mediating and moderating role that positive psychological factors play in the association between pain intensity and pain interference in individuals with chronic musculoskeletal pain. A descriptive cross-sectional study using mediation analyses was conducted, including 186 individuals with chronic musculoskeletal pain. We conducted cross-sectional mediation and moderation analyses to determine whether the positive psychological factors mediated or moderated the association between pain intensity and pain interference. Pain acceptance, pain self-efficacy, and optimism were all significantly and weakly related to pain interference when controlling for pain intensity. Pain self-efficacy and pain acceptance partially mediated the association between pain intensity and pain interference. On the other hand, the multiple mediation model did not show significant effects. The three positive psychological factors were not found to significantly moderate the association between pain intensity and pain interference. The findings suggest that in chronic musculoskeletal pain patients, the treatments may focus on [i] what they are capable of doing to manage the pain (i.e., pain self-efficacy) and [ii] being better able to accept the pain as pain waxes and wanes might be also particularly helpful. However, these results must be tested in longitudinal studies before drawing any causal conclusion.

Pain Neuroscience Education Plus Usual Care Is More Effective Than Usual Care Alone to Improve Self-Efficacy Beliefs in People with Chronic Musculoskeletal Pain: A Non-Randomized Controlled Trial

Self-efficacy beliefs are associated with less physical impairment and pain intensity in people with chronic pain. Interventions that build self-efficacy beliefs may foster behavioral changes among this population. A non-randomized trial has been carried out to evaluate the effectiveness of pain neuroscience education (PNE) plus usual care in modifying self-efficacy beliefs, pain intensity, pain interference and analgesics consumption in people with chronic musculoskeletal pain. Participants were allocated to an experimental (PNE plus usual care, n = 49) and a control (usual care alone, n = 51) group. The primary outcome was self-efficacy beliefs (Chronic Pain Self-Efficacy Scale), and the secondary outcomes were pain intensity, pain interference (Graded Chronic Pain Scale) and analgesics consumption. The participant's pain knowledge (revised Neurophysiology of Pain Questionnaire) after PNE intervention was also assessed to analyze its influence on every outcome measure. All the outcome measures were assessed at the baseline and at four-week and four-month follow-ups. PNE plus usual care was more effective than usual care alone to increase self-efficacy beliefs and decrease pain intensity and pain interference at all follow-up points. No differences between groups were found in terms of analgesics consumption. Knowledge of pain neurophysiology did not modify the effects of PNE plus usual care in any of the outcome measures. These results should be taken with caution because of the non-randomized nature of this design, the limited follow-ups and the uncertainty of the presence of clinical changes in self-efficacy for participants. Larger, methodological sound trials are needed.

Profiles of Women With Fibromyalgia and Social Comparison Processes

Background

Due to uncertainty regarding chronic pain in Fibromyalgia (FM) patients, there has been a growing interest in social comparison and its influence on emotional responses.

Aims

to analyze profiles in FM patients according to pain perception, social comparison strategies and anxiety and depression.

Methods

The sample consisted of 131 FM outpatients (Mean age: 50.15, SD = 11.1). Two scales were used: the Social Comparison Illness Scale and the Hospital Anxiety and Depression Scale.

Results

Two profiles were found by cluster analysis (K-means method): one (66%) with a higher level of pain perception, anxiety and depression and greater use of upward contrast and downward identification social comparison; and another (34%) with lower levels of pain perception, anxiety and depression and greater use of upward identification and downward contrast.

Conclusion

These profiles underline the interest in social comparison strategies and their role in FM.

Evaluation of Learned Helplessness, Perceived Self-efficacy, and Functional Capacity in Patients With Fibromyalgia and Rheumatoid Arthritis

OBJECTIVES

The aims of this study were to compare learned helplessness (LH) and perceived self-efficacy (SE) in patients with fibromyalgia (FM) and rheumatoid arthritis (RA) and to assess their correlation with functional disability, level of perceived pain, and fatigue.

METHODS

This multicenter, cross-sectional study included consecutive patients (aged ≥18 years) with RA, according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria, and FM, according to 2010 American College of Rheumatology criteria. Learned helplessness was measured by the Rheumatology Attitude Index, Spanish version; SE with the Arthritis Self-efficacy Scale, Spanish version; functional capacity with the Health Assessment Questionnaire (HAQ), Argentine version; depression with Center for Epidemiological Studies-Depression Scale 7-item version and perceived pain and fatigue by the visual analog scale. Disease activity was measured by the Clinical Disease Activity Index (CDAI) and disease impact with the Fibromyalgia Impact Questionnaire (FIQ).

RESULTS

A total of 215 patients, 100 with FM and 115 with RA, were included. Mean age was 59 (SD, 14) years and 58 (SD, 13) years for FM and RA, patients respectively. Whereas LH and depression were significantly higher, SE was significantly lower in FM patients. We found a positive correlation between LH and HAQ, pain, depression, fatigue, FIQ, and CDAI in FM and RA patients. We observed a negative correlation between SE and HAQ, pain, depression, fatigue, FIQ (FM), and CDAI (RA) in both groups.

CONCLUSIONS

Both LH and SE correlate significantly with functional capacity, perceived pain, disease activity, and disease impact in RA and FM patients. Learned helplessness was higher in patients with active disease or high disease impact, as opposed to those in remission or with low disease impact, and the reverse was true for SE. Patients with FM had significantly more LH, pain, fatigue, and depression and less SE compared with those with RA.

Assessment of hand function and disability in fibromyalgia

OBJECTIVE

Fibromyalgia, a potentially debilitating chronic pain syndrome, is a chronic disease. We aimed to compare the hand function of fibromyalgia (FM) patients and healthy individuals and to demonstrate the relationship between hand disability and FM.

PATIENTS AND METHODS

The study was consisted of 40 female patients with FM and 30 healthy controls. All participants were evaluated for pain threshold measurements, handgrip strength, and pinch strength. Functional states, hand disability, and hand skills and coordination were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) form, the Disability of Arm-Shoulder-Hand (DASH) questionnaire and the Purdue Pegboard Test, respectively.

RESULTS

Handgrip strength values, DASH score, lateral pinch strength test, Pegboard placement time, and Pegboard collection time of the patient group were significantly lower than those of the control group (all p < 0.05). A negative correlation was found between FIQ score and handgrip strength, two-point pinch strength test, three-point pinch strength test, and lateral pinch strength test in patients with moderate FM (all p < 0.05). Furthermore, a correlation was observed between DASH score and handgrip strength, lateral pinch strength test, Purdue Pegboard placement time, and Purdue Pegboard collection time in patients with moderate FM (all p < 0.05).

CONCLUSIONS

Our results show that hand function was decreased in patients with FM compared to healthy controls and decreasing hand function was influenced by FIQ score. As a result, the evaluation of hand function should be taken into consideration in the management of FM.

Benefits of a Home Treatment Program Using Guided Imagery Relaxation Based on Audio Recordings for People With Fibromyalgia

Despite the plethora of treatments available for patients with fibromyalgia, there is insufficient evidence to date as to what the ideal treatment approach is. This study sought to determine the effectiveness of a home program of audio-recorded guided imagery relaxation on people with fibromyalgia. This experimental 8-week longitudinal trial design was undertaken with 60 people diagnosed with fibromyalgia who were randomly assigned to either a guided imagery intervention group or a control group. Pain at tender points, anxiety, self-efficacy, quality of sleep, quality of life, and the impact of the fibromyalgia were determined at baseline, at 4 weeks, and at 8 weeks. After the guided imagery intervention, we found significant differences regarding trait anxiety, sleep quality, and tenderness at some of the tender points. There is a need, therefore, to develop and evaluate interventions that may enhance the quality of life of those affected by this disorder.

Psychological impact of fibromyalgia: current perspectives

Fibromyalgia syndrome (FMS) is a chronic disorder characterized by widespread and persistent musculoskeletal pain and other frequent symptoms such as fatigue, insomnia, morning stiffness, cognitive impairment, depression, and anxiety. FMS is also accompanied by different comorbidities like irritable bowel syndrome and chronic fatigue syndrome. Although some factors like negative events, stressful environments, or physical/emotional traumas may act as predisposing conditions, the etiology of FMS remains unknown. There is evidence of a high prevalence of psychiatric comorbidities in FMS (especially depression, anxiety, borderline personality, obsessive-compulsive personality, and post-traumatic stress disorder), which are associated with a worse clinical profile. There is also evidence of high levels of negative affect, neuroticism, perfectionism, stress, anger, and alexithymia in FMS patients. High harm avoidance together with high self-transcendence, low cooperativeness, and low self-directedness have been reported as temperament and character features in FMS patients, respectively. Additionally, FMS patients tend to have a negative self-image and body image perception, as well as low self-esteem and perceived self-efficacy. FMS reduces functioning in physical, psychological, and social spheres, and also has a negative impact on cognitive performance, personal relationships (including sexuality and parenting), work, and activities of daily life. In some cases, FMS patients show suicidal ideation, suicide attempts, and consummated suicide. FMS patients perceive the illness as a stigmatized and invisible disorder, and this negative perception hinders their ability to adapt to the disease. Psychological interventions may constitute a beneficial complement to pharmacological treatments in order to improve clinical symptoms and reduce the impact of FMS on health-related quality of life.

Postural counseling represents a novel option in pain management of fibromyalgia patients

Background

Chronic pain is a key symptom in fibromyalgia (FM), and its management is still challenging for rheumatologists in daily practice. FM patients show psychological and psychiatric manifestations, going from mood and emotional disorders to depression and alexithymia that negatively impact their quality of life, limiting their daily activities. Since pharmacological strategies have a limited efficacy in FM pain, alternative or complementary non-pharmacological approaches have been introduced in the clinical management of FM.

Patients and methods

This is a retrospective study on FM patients (n=52) treated with a novel integrated postural counseling (PC) rehabilitation program carried out by a counselor physiotherapist. The clinical impact of PC was evaluated by 1) a semi-structured interview using an ad hoc modified questionnaire McGill Illness Narrative Interview (MINI) 1 to obtain data on pain management by highlighting everyday experience of living with pain and 2) an FM impact questionnaire (FIQ) total score.

Results

Two main structures of narrative emplotment of FM illness were recognized: 1) the cumulative life narrative structure (46.15%) and 2) the broken life (53.85%) narrative structure. Baseline FIQ score was 77.38±7.77, and it was significantly reduced after PC to 39.12±13.27 (P<0.0001). Although well-being still requires further definition as outcome in pain management, it is important for FM patients, dealing with pain-related sensations, thoughts and feelings and limiting their daily activities. In our study, 87.5% of interviewed FM patients reported an improvement in their well-being after PC.

Conclusion

Our data suggest that an integrated PC program positively impacts chronic pain and fatigue based on self-management strategies. PC allows FM patients to resume their own life and regenerate their own image. Finally, we propose the introduction of the evaluation of the ability to resume daily activities as the target of rehabilitation programs in FM.

You get used to it, or do you: symptom length predicts less fibromyalgia physical impairment, but only for those with above-average self-efficacy

To determine whether the effects of symptom duration on fibromyalgia physical impairment are moderated by symptom self-efficacy, data from 572 female participants, who were members of a large health maintenance organization and had a diagnosis of fibromyalgia syndrome (FMS) were assessed. Age, symptom duration, history of physical, sexual, and emotional abuse, fibromyalgia-specific self-efficacy (Arthritis Self-Efficacy Scale adapted for FMS [ASES]), depression (Centers for Epidemiological Studies Depression Scale [CES-D]), fibromyalgia physical impairment (Fibromyalgia Impact Questionnaire [FIQ]), and pain (McGill Present Pain Index [PPI]) were measured five times across 18 months. Linear regressions were performed to predict baseline FIQ and PPI cross-sectionally. Of primary interest was a hypothesized interaction between ASES and symptom duration, which was significant in relation to FIQ but not PPI. Multilevel mixed models were performed to determine whether the same pattern existed longitudinally controlling for baseline symptom duration as an effect of time and ASES. The interaction was significant in the models for both FIQ and PPI. These results suggest that the effects of age and symptom duration on FMS are unique, and that self-efficacy plays a crucial role in moderating disease course (measured by symptom duration or time) in FMS.

Cognitive Impairments in Fibromyalgia Syndrome: Associations With Positive and Negative Affect, Alexithymia, Pain Catastrophizing and Self-Esteem

Fibromyalgia syndrome (FMS) is a chronic condition characterized by widespread pain accompanied by symptoms like depression, anxiety, sleep disturbance and fatigue. In addition, affected patients frequently report cognitive disruption such as forgetfulness, concentration difficulties or mental slowness. Though cognitive deficits in FMS have been confirmed in various studies, not much is known about the mechanisms involved in their origin. This study aimed to investigate the contribution of affect-related variables to cognitive impairments in FMS. For this purpose, 67 female FMS patients and 32 healthy control subjects completed a battery of cognitive tests measuring processing speed, attention, visuospatial and verbal memory, cognitive flexibility and planning abilities. In addition, participants completed self-report questionnaires pertaining to positive and negative affect, alexithymia, pain catastrophizing and self-esteem. Clinical characteristics including pain severity, symptoms of depression and anxiety, insomnia and fatigue were also assessed. FMS patients showed markedly poorer performance than healthy controls in all of the cognitive domains assessed, in addition to greater levels of depression, anxiety, negative affect, alexithymia and pain catastrophizing, and lower self-esteem and positive affect. In exploratory correlation analysis in the FMS sample, lower cognitive performance was associated with higher pain severity, depression, anxiety, negative affect, alexithymia and pain catastrophizing, as well as lower self-esteem and positive affect. However, in regression analyses, pain, self-esteem, alexithymia, and pain catastrophizing explained the largest portion of the variance in performance. While interference effects of clinical pain in cognition have been previously described, the present findings suggest that affective factors also substantially contribute to the genesis of cognitive impairments. They support the notion that affective disturbances form a crucial aspect of FMS pathology, whereas strategies aiming to improve emotional regulation may be a beneficial element of psychological therapy in the management of FMS.

Pain, Racial Discrimination, and Depressive Symptoms among African American Women

African American women with osteoarthritis (OA) are at high risk of experiencing pain. They report more pain than non-Hispanic White women and men of other racial/ethnic groups. This pain can limit independence and diminish their quality of life. Despite the detrimental effects that pain can have on older African American women with OA, there is a dearth of literature examining factors beyond the OA pathology that are associated with pain outcomes within this population. The purpose of this study was to examine the relationships between racial discrimination and depressive symptoms with pain intensity in African American women with OA. The sample comprised of 120 African American women, aged 50-80 years, with OA, from Texas and New Mexico. The women completed survey booklets to answer study questionnaires. We used multiple linear regression to test associations between racial discrimination, depressive symptoms, and pain intensity. We tested whether depressive symptoms mediated the relationship between racial discrimination and pain intensity by using bootstrapping. Results indicated that racial discrimination was significantly associated with pain intensity and that this relationship was mediated by depressive symptoms, even after controlling for body mass index, years of education, and length of time with OA. Both depressive symptoms and racial discrimination may be modifiable. If these modifiable factors are addressed in this population, there may be decreased pain in middle-aged and older African American women.

Illness beliefs among patients with chronic widespread pain - associations with self-reported health status, anxiety and depressive symptoms and impact of pain

Background

Chronic widespread pain (CWP) is a disabling condition associated with a decrease in health. Illness beliefs are individual and are acquired during life. Constraining beliefs may prevent patients from regaining health. Understanding these patients’ illness beliefs may be a way to improve the health care they are offered. The aim of this study was to describe illness beliefs among patients with CWP and associations with self-reported health, anxiety and depressive symptoms, and impact of pain.

Method

In this cross-sectional study, questionnaires were sent by mail to 330 patients including socio-demographic information, the Illness Perception Questionnaire (IPQ-R), the Short-Form General Health Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS). Data were analysed using descriptive statistics, non-parametric tests and linear regression analyses.

Results

Patients experienced and related a high number of symptoms to CWP (mean (SD) 9 (3)). The patients believed their illness to be long lasting, to affect their emotional well being, and to have negative consequences for their lives. Some 72% reported having severe or very severe pain, and impact of pain according to SF-36 was negatively correlated to several illness beliefs dimensions, anxiety- and depressive symptoms. In regression analyses, the Identity, Consequences and Personal control dimensions of IPQ-R and Anxiety- and Depressive symptoms explained 32.6–56.1% of the variance in the two component scores of SF-36.

Conclusion

Constraining illness beliefs in patients with CWP are related to worse health status, especially in cases of high number of physical or mental symptoms, beliefs of negative consequences or the illness affecting them emotionally. Identification and understanding of these beliefs may reduce patients’ suffering if they are taken into consideration in rehabilitation programs and in development of new evidence-based interventions aimed at increasing health in patients with CWP.

Are the changes in observed functioning after multi-disciplinary rehabilitation of patients with fibromyalgia associated with changes in pain self-efficacy?

OBJECTIVE

To examine the hypothesis that change in pain self-efficacy is associated with observed and self-reported activity, pain intensity, catastrophizing, and quality of life after multi-disciplinary rehabilitation of fibromyalgia patients.

DESIGN

In-depth analyses of secondary outcomes of a randomized-controlled trial.

SUBJECTS

Women (N = 187) with fibromyalgia.

METHODS

Outcomes were Pain Self-Efficacy, Assessment of Motor and Process Skills (AMPS), SF-36 Physical Function (SF-36-PF), pain intensity, and SF-36 Mental Composite Score (SF-36-MCS) to assess quality of life and pain catastrophizing. Individual and group associations between outcomes were examined.

RESULTS

Individual changes in pain self-efficacy were not associated with changes in observed activity: AMPS motor (r_s = 0.08, p = 0.27) and process (r_s = 0.12, p = 0.11), not even in those patients with a clinically relevant improvement in observed functioning (38.5%), and only weakly or moderatly with changes in SF-36-PF; (r_s = 0.31, p < 0.0001), SF-36-MSC; (r_s = 0.41, p < 0.0001), and pain catastrophizing (r_s = -0.31, p < 0.0001). No differences in pain self-efficacy were observed between the rehabilitated group and controls (difference: 1.61; 95% CI: -0.84 to 4.06; p = 0.24). However, a subgroup (34%) had a clinically relevant improvement in pain self-efficacy. This group was younger (mean age 41.4 vs. 45.8, p = 0.01), more recently diagnosed (1.8 vs. 2.8 years, p = 0.003), but had an unresolved welfare situation (59% vs. 40%, p = 0.02).

CONCLUSION

The main hypothesis was falsified, as there was no association between pain self-efficacy and actual performance of activity. The relation to functioning may be limited to perceived, cognitive-emotional aspects, as indicated by the weak to moderate correlations to the self-reported measures. Implications for Rehabilitation Improvement in observed activity post multi-disciplinary rehabilitation was not associated with change in pain self-efficacy. Patients performed better after rehabilitation, but did not perceive to have improved their capacity. The relationship between pain self-efficacy and functioning may be limited to cognitive-emotional aspects rather than actual activity. Both observational and self-reported measures should be included in evaluating outcomes of rehabilitation for patients with fibromyalgia.

Self-Regulatory Fatigue: A Missing Link in Understanding Fibromyalgia and Other Chronic MultiSymptom Illnesses

OBJECTIVE

Patients with chronic multisymptom illnesses such as fibromyalgia syndrome (FMS) are experiencing a multitude of physical and mental challenges. Facing such challenges may drain capacity to self-regulate, and research suggests patients with these illnesses may experience self-regulatory fatigue (SRF). This study sought to examine whether SRF can be associated with quality of life (QoL) in patients with FMS.

METHODS

Patients (N = 258) diagnosed with FMS completed self-report measures related to demographics, SRF (Self-Regulatory Fatigue 18 [SRF-18]), anxiety (Generalized Anxiety Disorder questionnaire [GAD-7]), depression (Patient Health Questionnaire [PHQ-9]), physical fatigue (Multidimensional Fatigue Inventory [MFI]), symptoms related to FMS (Fibromyalgia Impact Questionnaire [FIQ]), and QoL (36-Item Short-Form Health Survey [SF-36]).

RESULTS

Hierarchical regressions showed higher SRF to be associated with lower QoL in terms of lower overall physical QoL, with subscales related to physical functioning, role limitations-physical, bodily pain, and general health (all P's > 0.001), as well as lower overall mental QoL, with subscales related to vitality, social functioning, role limitations-emotional, and mental health (all P's > 0.001). Including traditional predictors such as anxiety, depression, physical fatigue, and FMS-related symptoms as covariates in the analyses reduced the link between SRF and QoL somewhat, but the associations remained generally strong, particularly for SRF and mental QoL.

CONCLUSION

This is the first study to show higher SRF relating to lower QoL for patients with FMS. Results suggest that SRF is distinct from anxiety, depression, and fatigue, and predicts QoL above and beyond these traditional factors in the area of chronic multisymptom illnesses such as FMS. SRF may be a "missing link" in understanding the complex nature of chronic multisymptom illnesses.
