Incorporating Family Function into Chronic Pain Disability: The Role of Catastrophizing

Pain intensity and self-perceived burden mediate the relationship between family functioning and pain catastrophizing in patients with neuropathic pain

This cross-sectional study aimed to investigate the relationship between family functioning, pain intensity, self-perceived burden, and pain catastrophizing. Moreover, we also wanted to explore the multiple mediating roles of pain intensity and self-perceived burden. From October 2022 to March 2023, 252 Chinese people with neuropathic pain completed face-to-face questionnaires to assess family functioning, pain intensity, self-perceived burden, and pain catastrophizing. Data analysis was done using descriptive statistics and a structural equation model. The results showed better family functioning was significantly associated with more intense pain, less self-perceived burden, and less pain catastrophizing. Mediation analysis showed that family functioning could indirectly affect pain catastrophizing through pain intensity and self-perceived burden in addition to a direct effect on pain catastrophizing. Moreover, the mediating variable of pain intensity played a masking role. These findings suggest that good family functioning can effectively reduce the self-perceived burden and pain catastrophizing in patients with neuropathic pain. However, family functioning cannot show its maximum effectiveness, and it may be necessary to construct a model of family functioning suitable for patients with neuropathic pain in the future.

The Effect of Family Nursing Conversations as an Add-on to Multidisciplinary Treatment in Patients with Chronic Non-Cancer Pain: A Quasi-Experimental Trial

Introduction

Chronic non-cancer pain (CNCP) is a lifelong condition with radical consequences, calling for management involving patients' families. Interventions based on the family systems nursing framework by Wright and Leahey have proved beneficial in other populations but require investigation in a CNCP population. This trial assumed that family nursing conversations (FNCs) based on the family systems nursing framework would increase patients' and family members' self-efficacy concerning CNCP management.

Objective

To investigate whether an intervention with FNCs as an add-on to the usual multidisciplinary treatment of CNCP would have an effect on patients' and family members' self-efficacy. Additionally, to investigate any impact on family function, health-related quality of life, anxiety, and depression.

Methods

The trial applied a prospective non-blinded quasi-experimental design with two comparable groups of patients and family members: a historical control group (HCG) and an intervention group (IG). The intervention was executed by nurses employed at a multidisciplinary pain center in the Capital Region of Denmark. HCG data were collected before the nurses' intervention training. The primary outcome was self-efficacy. Secondary outcomes were family function, health-related quality of life, anxiety, and depression.

Results

In total, 58 patients and 85 family members were included. The primary outcome, self-efficacy, detected no statistically significant between-group differences in mean change for patients, p = .990, or family members, p = .765. A statistically significant effect in favor of the IG was found in between-group differences in mean change in patients' behavioral family function, p = .034, and anxiety, p = .031. No statistically significant between-group differences were detected in family members' secondary outcomes.

Conclusion

The intervention had no effect on patients' or family members' self-efficacy but a positive effect on patients' behavioral family function and anxiety. The intervention was deeply affected by the COVID-19 pandemic. Hence, any results should be interpreted with caution.

Family strain, but not family support, is linked to worse pain interference among midlife adults reporting new chronic pain

INTRODUCTION

Although family relationship quality has been linked to later chronic pain incidence for aging adults, it is unclear whether the quality of these relationships is linked to the impact of pain. We estimated longitudinal associations between family relationship quality (i.e., family support and family strain) and pain interference for adults who develop novel chronic pain across 10 years of midlife.

METHOD

We conducted a secondary analysis of data from the Midlife in the United States (MIDUS) study. Using path analysis, we tested whether family support and strain reported by participants (54% female, age M = 54.8 years) who denied having chronic pain at the study's second wave (MIDUS 2, 2004-2006) but reported chronic pain 10 years later (MIDUS 3, 2014-2016; N = 406) was associated with the interference of that pain with daily activities after accounting for key covariates, including sociodemographics, depression symptoms, global physical health, and MIDUS 3 reports of family support and strain.

RESULTS

The hypothesized model demonstrated good fit to the data based on multiple model fit indices. Greater family strain at baseline, but not family support, was significantly associated with greater pain interference 10 years later.

DISCUSSION

Findings build on prior studies to suggest that not only are stressful family relationships likely associated with the odds of developing chronic pain, but they are also linked to the interference of that chronic pain when it develops. We recommend biopsychosocial screening in primary care that captures family relationship quality and can inform best practices for nonpharmacological, family-based pain management.

Psychological Factors Mediate the Relationship between Physical Activity and Goal Attainment for Occupational Therapy Practice: An Observational Study in Japan

Occupational therapy can improve physical activity, anxiety, and goal achievement after high tibial osteotomy. However, the role of psychological factors in physical activity and goal attainment after high tibial osteotomy is unclear. We examined how psychological factors mediate the relationship between physical activity and goal achievement. Participants included 55 individuals post-high tibial osteotomy. Physical activity and performance and satisfaction in everyday tasks had a significant indirect effect on the anxiety and depression. Anxiety and depression mediated the physical activity-goal attainment relationship. Thus, occupational therapy practices focusing on anxiety and depression may be important in post- high tibial osteotomy rehabilitation.

Examining pain severity in women with rheumatoid arthritis: the impact of pain self-efficacy and perceived partner's emotional support

BACKGROUND

Empirical data suggest that psychosocial factors, such as pain self-efficacy (PSE) and emotional support from a partner, may alleviate the suffering caused by rheumatoid arthritis (RA) pain. However, the data are ambiguous and warrant a more comprehensive investigation into the effect of these factors on the severity of RA pain. The objective of the present study was to assess the significance of PSE and emotional support from a partner in relation to pain severity among women with RA.

PARTICIPANTS AND PROCEDURE

The study included a sample of 196 women diagnosed with RA with the mean age of 41.54. The study employed the following measures: Rheumatoid Arthritis Pain Scale, Pain Self-efficacy Questionnaire, and Communication Based Emotional Support Scale.

RESULTS

The analysis revealed that higher PSE emerged as the strongest predictor for lower pain severity across all components of RA pain. However, the impact of the partner's emotional support on pain severity was not as evident and varied depending on the specific pain component. Furthermore, the use of pain medications significantly predicted three out of four pain components. Mediation analysis revealed that perceived emotional support from a partner directly affected women's RA pain intensity, as well as indirectly through the PSE as a mediator. Moderated mediation analysis demonstrated that the association between PSE and pain severity weakened as the duration of RA increased.

CONCLUSIONS

Enhancing women's PSE and providing appropriate training for their partners to offer effective emotional support may play a crucial role in the treatment of RA.

Family dysfunction is associated with chronic pain in a community-dwelling Japanese population: The Hisayama study

BACKGROUND

Poor family functioning has been reported to be associated with the severity of chronic pain in outpatients, but the association has not been fully addressed in general populations. The present study aimed to examine the association between family dysfunction levels and the presence of chronic pain in a community-dwelling Japanese population.

METHODS

A total of 2598 participants aged ≥40 years were classified as having healthy, borderline or unhealthy family functioning. Chronic pain was defined as subjective pain for three months or longer, and further classified by pain intensity, the number of chronic pain sites, pain duration and the extent of pain spread. A logistic regression model was used to compute the odds ratios (ORs) for chronic pain outcomes.

RESULTS

The prevalence of chronic pain was 49%. The age- and sex-adjusted prevalence of total and severe chronic pain were increased significantly with increasing family dysfunction levels (all p for trend <0.01). After adjusting for sociodemographic, physical, social and family structure factors, the ORs (95% confidence intervals [CI]) for having chronic pain among borderline and unhealthy groups were 1.20 (1.01-1.44) and 1.43 (1.15-1.79), respectively, as compared with a healthy family function group. The association was stronger among people who were employed and those who were living with their children. In addition, the ORs for severe chronic pain increased significantly with increasing levels of family dysfunction.

CONCLUSIONS

The family dysfunction level was positively associated with the presence as well as the severity of chronic pain in a community-dwelling population.

SIGNIFICANCE

A biopsychosocial burden due to family relationships could worsen the clinical presentation of pain. Social support or family therapy for dysfunctional families would be a potential initiative for the prevention or management of chronic pain.

Factors that influence the impact of Chronic Non-Cancer Pain on daily life: A partial least squares modelling approach

BACKGROUND

Chronic Non-Cancer Pain is pain of more than three months' duration and is not associated with an oncological condition. There is ample literature that recognises that Chronic Non-Cancer Pain impacts numerous areas of the life of the person who suffers from it. This impact is difficult to determine and quantify because Chronic Pain is a subjective experience.

OBJECTIVE

The objective of this study was to test a recursive model of hypothesised factors that comprise the concept of Chronic Non-Cancer Pain Impact on daily life using Partial Least Squares-Structural Equation Modelling.

DESIGN

A cross-sectional study was carried out. The sample size was calculated using G*Power V.3.1.9.4 with five parameters (two-tailed, large effect size (f² = 0.35), power of 0.95, statistical significance of 95% (α = 0.05) and 36 predictors). The minimum number of subjects was considered to be 137.

METHODS

A recursive model was built based on data from a sample of 395 people over 18 years of age with Chronic Non-Cancer Pain. Data collection was conducted between January and March 2020 at Pain Units and Primary Healthcare Centres belonging to the Spanish Public Health System in the province of Seville (Spain). Analyses were based on Partial Least Squares-Structural Equation Modelling. The internal consistency, convergent validity and discriminant validity of the internal measurement model were assessed. For the external measurement model, global model adjustment and structural validity were assessed. The predictive capacity of the final model was also evaluated. All analyses were performed using SmartPLS version 3.3.2 in consistent mode.

RESULTS

Findings showed an adequate validity of the proposed model, which comprised nine factors: pain catastrophising, hopelessness due to pain, support network, proactivity, treatment compliance, self-care, mobility, resilience, and sleep. The internal validity of the model (Cronbach's alpha and rho_A > 0.70; Average Variance Extracted>0.50; standardised outer loadings>0.60; Heterotrait-Monotrait-Ratio < 0.85), goodness of fit (Standardised Root Mean Square Residuals<0.08; Geodesic and Euclidean distance p-value<0.05) and predictive power with out-of-sample values (Stone-Geisser test>0.5) were adequate. The hypothesised structure of the instrument has also been confirmed (path coefficients>0.3; R² > 0.1; f² > 0.2).

CONCLUSIONS

The results have shown an adequate internal consistency, convergent validity and discriminant validity of the model. Likewise, the model has shown an adequate goodness of fit, and the validity of its structure and the hypothesis have been confirmed. However, more research is needed in this regard as the possible interaction between the different factors evaluated in the model with the confounding or moderating variables that may exist.

Evaluating the Relationship Between Depression and Pain Anxiety with Pain Catastrophizing in Patients with COVID-19

Background

This study aimed to investigate the relationship between depression and pain anxiety with pain catastrophizing in patients with coronavirus disease 2019 (COVID-19).

Methods

In this descriptive, correlational study, 180 patients with COVID-19 in Akhtar and Imam Hossein hospitals in Tehran, Iran, were included from March 2019 to April 2020. All participants completed three questionnaires, including the Pain Catastrophizing Scale (PCS), Pain Anxiety Symptoms Scale (PASS), and Beck’s Depression Inventory (BDI). The data were analyzed using Pearson correlation coefficient and multivariate regression.

Results

There was a positive and significant relationship between the dimensions of rumination, magnification, and helplessness with total score of pain catastrophizing, as well as moderate to severe dimensions with total pain anxiety and depression in patients with COVID-19.

Conclusions

According to the results of regression analysis, pain anxiety based on pain catastrophizing dimensions was statistically significant, so that rumination, magnification, and helplessness could predict pain anxiety and explain a total of 15.1% of changes in pain anxiety. Also, depression was statistically significant based on dimensions of pain catastrophizing, so rumination, magnification, and helplessness could predict the patients’ depression and explain 13.6% of depression changes.

Parental Pain Catastrophizing, Communication Ability, and Post-surgical Pain Outcomes Following Intrathecal Baclofen Implant Surgery for Patients With Cerebral Palsy

There is strong evidence that psychosocial variables, including pain catastrophizing, influence parental and child ratings of pain, pain expression, and long-term outcomes among children with chronic pain. The role of these factors among children who have communication deficits due to cerebral palsy (CP) and other intellectual and developmental disabilities is currently unclear. In this study, parental pain catastrophizing was assessed before intrathecal baclofen (ITB) pump implantation for spasticity management in 40 children and adolescents with CP, aged 4 to 24 years. Pain was assessed before and after surgery with two methods: a parent-reported pain interference scale, and behavioral pain signs during a standardized range of motion exam. Linear mixed models with clinical/demographic factors and scores from the Pain Catastrophizing Scale for Parents (PCS-P), and child spoken language ability as predictors and the pain variables as the outcomes were implemented. On average, both pain outcomes improved after surgery. Only child spoken language ability predicted change in behavioral reactivity scores, with children with phrase speech showing an increase in reactivity at follow-up compared to pre-surgery levels, on average. A significant interaction between PCS-P scores and spoken language ability on change in pain interference scores over time showed that dyads with children with phrase speech whose parents reported high PCS-P scores reported the least improvement in pain interference at follow-up. Due to the preliminary nature of the study, future work is needed to investigate the parental behaviors that mediate the relationships between parental catastrophizing and pain outcomes in this population.

Design and preliminarily validation of a tool to assess the impact of chronic non-cancer pain on people's daily life in Spanish-language: PAIN_Integral Scale©

AIM

To build and preliminarily validate a Spanish-language instrument to assess the impact that CNCP has on the daily lives of people who suffer from it.

BACKGROUND

The experience of pain is multifactorial and a correct assessment of it helps to control the intensity of pain. Although there are instruments that evaluate areas on which Chronic Non-Cancer Pain impacts, it would be necessary to include other aspects that scientific literature identifies as relevant.

DESIGN

Instrument and construct cross-sectional study for psychometric validation.

METHODS

A total of 157 items based on items from validated questionnaires were evaluated by a group of 21 chronic pain experts using Delphi methodology in three evaluation rounds. A final questionnaire of 55 items with a 5-point Likert-type scale was formed. This questionnaire was piloted on a total of 30 patients to assess their understanding of the items and the psychometric validation process was carried out (January to March 2020) on a subsequent sample of 395 people, all of whom attended Pain Units and Primary Care Centres of the Public Health System in Spain.

RESULTS

The PAIN_Integral Scale^© showed acceptable internal consistency scores measured by Cronbach's alpha. Exploratory Factor Analysis indicated a structure of nine factors that explain 71.02% of the total variance, from 157 to a final total of 36 items. Confirmatory Factor Analysis showing adequate values confirmed this structure. The effect size was used to calculate the cut-off points for the overall scale, setting them at scores of 130 and 135.

CONCLUSION

This instrument would allow to assess other constructs and dimensions not included in the instruments previously available such as treatment compliance, proactivity, resilience, hopelessness due to pain and pain catastrophizing. However, despite the fact that the preliminary analysis shows good results, it is necessary to continue with its validation process in subsequent studies.

IMPACT

The PAIN_Integral Scale^© , once the validation process is finished, could be a complete enough instrument to allow a comprehensive healthcare assessment of Chronic Non-Cancer Pain's impact on daily nursing clinical practice and other healthcare professionals.

Implementation of the McMaster Model in Family Therapy: Effects on Family Function in Married Couples

Objective: Family function is one of the main effective factors on stability of the family. Family therapy can promote family function and performances. This study aimed to assess the effects of family therapy on family function among couples in Yazd province (Iran) based on the McMaster model.

Method: The research population was selected from volunteer couples in Yazd in 2017 who were invited by publicity announcement to participate in this research. Finally, 40 couples were selected and randomly divided into 2 intervention and control groups. Participants answered to the demographic and Family Assessment Device (FAD) questionnaires. The acquired information was analyzed using inferential and descriptive statistics and SPSS 21 software.

Results: The outcomes showed significant differences between the intervention and control groups in problem-solving (p = 0.01), communication (p < 0.0001), emotional responsiveness (p = 0.01), emotional involvement (p < 0.0001), and general function (p = 0.04). The roles and behavior control domains were improved after the intervention in 2 groups, but the differences were not significant.

Conclusion: Family therapy based on McMaster model can promote the skills of problem- solving, family communication, emotional responsiveness, emotional involvement, and general function in couples. Healthy family functioning is a substantial domain of concern for mental health specialists who provide family interventions. Our findings enhance considerably to family professionals’ knowledge about patterns of family function in Iranian families.

Prevalence and Associated Factors of Depressive Symptoms Among Patients With Chronic Low Back Pain: A Cross-Sectional Study

Background: Few studies have focused on depressive symptoms among patients with chronic low back pain in China. The aim of this cross-sectional study was to assess the prevalence and associated factors of depressive symptoms in patients with chronic low back pain. Methods: From May to August 2021, 1,172 patients with chronic low back pain were recruited in China. Depressive symptoms were assessed through the Patient Health Questionnaire. Associations of demographic characteristics, clinical characters and social-psychological factors with depressive symptoms were investigated among patients with chronic low back pain. Results: The prevalence of depressive symptoms was 25.00%. Logistic regression analysis found that duration of pain in 1-5 years (1-3 years: OR = 2.91, 95%CI: 1.65-5.14, 3-5 years: OR = 3.09, 95%CI: 1.55-6.15) and more severe pain (OR = 1.13, 95%CI: 1.10-1.17) were associated with higher risks of depressive symptoms. Better family function (good family function: OR = 0.25, 95%CI: 0.15-0.41, moderate family dysfunction: OR = 0.47, 95%CI: 0.29-0.77) and higher pain self-efficacy (OR = 0.94, 95%CI: 0.93-0.95) were associated with lower risks of depressive symptoms. Conclusion: Patients with chronic low back pain have a high prevalence of depressive symptoms in China. Duration of pain, pain severity, family function and pain self-efficacy were predictors of depressive symptoms among chronic low back pain patients in China. Early identification of the associated factors may be helpful for the timely management of depressive symptoms.

Subjective suffering in patients with low back pain

AIM

Low back pain (LPB) is a prevalent rheumatic and musculoskeletal disease and patients often experience physical discomfort and functional limitations. This study aimed to evaluate how subjective suffering relates to illness perceptions, pain intensity and psychological morbidity as well as to understand the mediator (direct and indirect) effects on functional disability.

METHODS

A cross-sectional study with 125 patients who received physiotherapy and answered the following instruments: Illness Perception Questionnaire-Revised; Illness Subjective Suffering Inventory; Hospital Anxiety and Depression Scale and the Oswestry LBP Incapacity Questionnaire.

RESULTS

In the structural equation modeling analysis, subjective suffering totally mediated the relationship between both emotional response (estimate = 0.068, 95% highest posterior density interval [HPDI] = [0.017, 0.133]), consequences (estimate = 0.118, 95% HPDI = [0.035, 0.211]) and functional disability. The relationship between coherence and disability was partially mediated by subjective suffering (estimate = -0.067, 95% HPDI = [-0.134, -0.016]). Only identity and pain intensity showed direct effects on functional disability.

CONCLUSION

Intervention in patients with LBP should focus on subjective suffering to reduce functional disability, providing information and promoting the acceptance of disease and pain.

The Relationship Between Ruminating the Catastrophic Consequences of Bodily Changes and Positive Reappraisal and Practical Problem-Solving Strategies in Individuals With Illness Anxiety Disorder

Introduction:

Cognitive emotion regulation is suggested to contribute to Illness Anxiety Disorder (IAD). Reappraisal and suppression are essential ER strategies with controversial data about their roles in IAD. Relevant studies are mostly limited to exploring these two strategies in individuals without such disorder. Therefore, we aimed to study the role of emotion regulation in the psychopathology of IAD by evaluating other ER strategies in illness-anxious individuals. Furthermore, we investigated the relationship between IAD and emotion regulation by targeting the role of interpretation bias for health-related information.

Methods:

The study participants were 60 university students. They underwent a semi-structured clinical interview to assess the presence or absence of IAD symptoms (n=30/group). They completed a battery of questionnaires measuring IAD, emotion regulation, and interpretation bias.

Results:

The illness-anxious group applied significantly less reappraisal and refocus on planning and more rumination, catastrophizing, and acceptance strategies, compared to the controls. Besides, interpretation bias was positively correlated with rumination and catastrophizing; while its association with reappraisal and planning was negative.

Conclusion:

Both functional (e.g. reappraisal & planning) and dysfunctional strategies (e.g. rumination & catastrophizing) contributed to the psychopathology of IAD. The biased interpretation of bodily information could make individuals prone to ruminate about the catastrophic consequences of bodily changes; such conditions interrupt fostering more positive reappraisal or practical problem-solving strategies.

Attentional control moderates the relationship between pain catastrophizing and selective attention to pain faces on the antisaccade task

Cognitive models of chronic pain emphasize the critical role of pain catastrophizing in attentional bias to pain-related stimuli. The aim of this study was (a) to investigate the relationship between pain catastrophizing and the ability to inhibit selective attention to pain-related faces (attentional bias); and (b) to determine whether attentional control moderated this relationship. One hundred and ten pain-free participants completed the anti-saccade task with dynamic facial expressions, specifically painful, angry, happy, and neutral facial expressions and questionnaires including a measure of pain catastrophizing. As predicted, participants with high pain catastrophizing had significantly higher error rates for antisaccade trials with pain faces relative to other facial expressions, indicating a difficulty disinhibiting attention towards painful faces. In moderation analyses, data showed that attentional control moderated the relationship between attentional bias to pain faces and pain catastrophizing. Post-hoc analyses demonstrated that it was shifting attention (not focusing) that accounted for this effect. Only for those with high self-reported ability to shift attention was there a significant relationship between catastrophizing and attentional bias to pain. These findings confirm that attentional control is necessary for an association between attentional bias and catastrophizing to be observed, which may explain the lack of relationships between attentional bias and individual characteristics, such as catastrophizing, in prior research.

Pain Catastrophizing Thoughts Explain the Link Between Perceived Caregiver Responses and Pain Behaviors of Patients With Chronic Musculoskeletal Pain

PURPOSE

Caregivers' responses to pain behaviors of patients with chronic pain have an essential role in how patients perceive their pain condition. The current study investigated the mediating role of pain catastrophizing on the link between perceived caregiver responses and patient pain behaviors.

MATERIALS AND METHODS

The sample of this cross-sectional study consisted of 200 patients with chronic pain (mean of age = 44.6; 71.5% were female). Participants responded to measures assessing their perception of their caregiver responses to their pain, their pain catastrophizing thoughts, and their pain behaviors.

RESULTS

The mediation analyses showed that perceived distracting responses were negatively related to pain catastrophizing level in patients, which in turn was positively associated with expressing pain behaviors. Besides, perceived caregiver negative responses were positively associated with catastrophizing thoughts, which in turn was positively related to expressing pain behaviors.

CONCLUSION

Patients' perceptions regarding how their caregiver responds to their pain condition can be related to their thoughts about their pain and how they react to their pain situation. Investigating the external sources that might have an impact on patients' reactions to their pain, especially when those external sources are caregivers who, in most situations, are with the patients for a prolonged duration, is essential.

Consequences of Chronic Non-Cancer Pain in adulthood. Scoping Review

OBJECTIVE

To examine and map the consequences of chronic pain in adulthood.

METHOD

Documents addressing the impact of chronic pain on the psychological and social spheres of people suffering from chronic pain, published in Spanish and English between 2013 and 2018, were included. Those who addressed pharmacological treatments, chronic pain resulting from surgical interventions or who did not have access to the full text were excluded. Finally, 28 documents from the 485 reviewed were included

RESULTS

Studies show that pain is related to high rates of limitation in daily activities, sleep disorders and anxiety-depression spectrum disorders. People in pain have more problems to get the workday done and to maintain social relationships. Chronic pain is also associated with worse family functioning.

CONCLUSIONS

This review shows that limitations in the ability to perform activities of daily living, sleep, psychological health, social and work resources and family functioning are lines of interest in published articles. However, knowledge gaps are detected in areas such as the influence of having suffered pain in childhood or adolescence, the consequences of non-fulfillment of working hours and gender inequalities.

Development and Validation of Fear of Relapse Scale for Relapsing-Remitting Multiple Sclerosis: Understanding Stressors in Patients

Chronic diseases are associated with patients' long-term stress and development of fear to things related to the source of stress. Better management of a patients' condition requires investigation of the underlying mechanisms that contribute to the process of development of chronic stress. Multiple Sclerosis (MS) is a debilitating chronic disease in most cases diagnosed after a relapse and characterized by the periodic occurrence of relapses in most patients. Due to the unpredictable course of the disease and relapses, patients with Relapsing-Remitting MS (RRMS) may deal with the stress of anticipation of relapse and its unpredictable consequences. The role of relapses and related stress on patients' quality of life has not been previously investigated. This study is the first effort to develop a self-report measure of Fear of Relapse (FoR) in patients with RRMS. Thirty-one items were extracted from in-depth clinical interviews with 33 RRMS patients to develop the preliminary version of the scale. Subsequently, 168 RRMS patients completed the questionnaire, the Intolerance of Uncertainty Scale (IUS) and Depression, Anxiety, and Stress Scale (DASS). Fifty-one patients completed the scale one more time a month later. Factor analysis revealed three components, and five items failed to load on any of them. To test the FoR's independence from similar measures, responses to 26 items were pooled once with DASS items and once with IUS items, and each time were subjected to confirmatory factor analysis (two-component solution). Despite significant correlations between FoR, DASS, and IUS Independent loadings of items belonging to FoR and DASS, and FoR and IUS revealed independence and unique contribution of FoR to the evaluation of patients. Cronbach's alpha for the 26-item version was 0.92. Test-retest reliability for total score was equal to 0.74. These findings provide preliminary evidence of the validity and reliability of the measure. This scale can help researchers and clinicians to have a more comprehensive understanding of patients' experience with the uncertain nature of MS, which is necessary for future efforts to address this stressor by targeting the underlying mechanism.

The mediating effect of psychological factors on the relationship between pain intensity and wrist joint function: a longitudinal study with mediation analysis

PURPOSE

Psychological factors and pain intensity are associated with wrist function. However, the mediating role of psychological factors in the relationship between pain intensity and wrist function in distal radius fractures remains unclear. We performed mediation analysis to investigate how psychological factors mediate the relationship between pain intensity and wrist function.

METHODS

Twenty-one patients with distal radius fractures were included in this longitudinal study. Patient-rated wrist evaluation, one pain intensity-related outcome measure (numerical rating scale), and three psychological outcome measures (pain catastrophizing scale, hospital anxiety and depression scale, and pain self-efficacy questionnaire) were assessed. The mediation analysis with a bootstrap sampling procedure was used to assess indirect effects. The level of significance was set at 5%.

RESULTS

Mediation analysis showed that the pain intensity, as measured by patient-rated wrist evaluation, had significant indirect effects on the hospital anxiety and depression scale-anxiety (95% bootstrapped confidence interval: 0.96-9.62) and pain self-efficacy questionnaire (95% bootstrapped confidence interval: 0.43-8.11) scores.

CONCLUSIONS

The relationship between pain intensity and wrist function was mediated by anxiety and self-efficacy. Our findings suggest that interventions focused on psychological factors, particularly anxiety and self-efficacy, may be important in distal radius fractures rehabilitation.IMPLICATIONS FOR REHABILITATIONIn patients with distal radius fractures, early post-operative pain mediates psychological factors and affects wrist function.Anxiety and self-efficacy are psychological factors that should be noted, and rehabilitation, including self-management, should be considered.Rehabilitative interventions for distal radius fractures should focus on psychological factors and management of post-operative pain.

Time course of attentional bias to painful facial expressions and the moderating role of attentional control: an eye-tracking study

Introduction

This study investigated the time course of attention to pain and examined the moderating effect of attentional control in the relationship between pain catastrophizing and attentional bias in chronic pain patients.

Methods

A total of 28 patients with chronic pain and 29 pain-free individuals observed pictures of pain, happy and neutral facial expressions while their gaze behaviour was recorded. Pain intensity and duration, anxiety, depression, stress, attentional control and pain catastrophizing were assessed by questionnaires.

Results

In all subjects, the pattern of attention for pain faces was characterized by initial vigilance, followed by avoidance. No significant difference was found between the two groups in terms of orientation towards the stimuli, the duration of first fixation, the average duration of fixation or number of fixations on the pain stimuli. Attentional control moderated the relationship between catastrophizing and overall dwell time for happy faces in pain patients, indicating that those with high attentional control and high catastrophizing focused more on happy faces, whereas the reverse was true for those with low attentional control.

Conclusion

This study supported the vigilance-avoidance pattern of attention to painful facial expressions and a moderation effect of attentional control in the association between pain catastrophizing and attentional bias to happy faces among pain patients.

Pain Intensity Is Not Always Associated with Poorer Health Status: Exploring the Moderating Role of Spouse Personality

Background

Past decades have seen a surge of studies investigating the role of spouses in chronic illness. The present study explored an interpersonal model of health-related quality of life in chronic pain settings. Spouse personality was tested as a moderator of pain intensity-to-health associations in patients with chronic pain.

Methods

This is a cross-sectional study. Participants were 185 noncancer chronic pain patients and their spouses. Patients were mostly females (58.4%). Mean age was approximately 56 years for patients and spouses. Patients completed a measure of pain intensity, health-related quality of life, and personality. Spouses also reported on their personality characteristics. Spouse personality was used as the moderator in the relationship between patients' pain intensity and health status. Patient personality was used as a covariate in the moderation analyses.

Results

Spouse neuroticism moderated the relationship between pain intensity and physical health status, while spouse introversion moderated the pain-to-mental health association.

Conclusions

Results support the idea that the relationship between a chronic stressor, namely, chronic pain, and health-related quality of life may be complex and contextually determined by spousal characteristics. Clinical implications are discussed in the context of couples.

Attentional Bias to Threat-Related Information Among Individuals With Dental Complaints: The Role of Pain Expectancy

Expecting pain can be perceived as a threat may involve recruitment of cognitive strategies (such as attentional avoidance) which might help the person to reduce distress. The ecological validity of the paradigms aiming to study the attentional biases toward or away from threatening stimuli by manipulating the perception of threat in experimental settings has been questioned. Therefore, the current study aims to investigate the attentional bias toward or away from the threat when a confrontation with a real threatening and painful condition would be expected (i.e., dental treatment). One hundred and twenty-seven patients referred to three dentistry clinics for a dental treatment (experiment participants) and 30 individuals with no dental complaints (control participants) completed this study. Patients were randomly allocated to a high pain expectancy (HPE: n = 65) or a low pain expectancy (LPE: n = 62) expectancy condition. All participants completed questionnaires of distress, fear of pain, and fear of dental pain. Furthermore, they participated in a dot-probe task that assessed their attention to painful faces, dental pictures, and happy faces. In addition, before the treatment, participants reported their anticipated pain intensity and after the treatment, they reported the pain intensity that they perceived during the treatment using two separate visual analog scales. Patients in the HPE group showed a bias away from dental pictures compared to LPE and control group participants. HPE group patients also reported greater pain intensity during the treatment compared to LPE patients. Greater attentional bias away from dental pictures among HPE patients was associated with higher levels of fear of pain, fear of dental pain, and stress. Avoidance of highly salient threatening images can be seen as an unhelpful emotion-regulation strategy that individuals use to manage their fears. However, in this study, avoidance was associated with poorer outcomes.

Improved health-related quality of life, participation, and autonomy in patients with treatment-resistant chronic pain after an intensive social cognitive intervention with the participation of support partners

Despite the availability of various specific treatments, most patients with chronic pain (CP) consider their pain problem as undertreated. Recently, multiple sclerosis (MS) patients who were given an intensive 3-day social cognitive treatment with the participation of support partners experienced lasting improvements in health-related quality of life (HRQoL) and self-efficacy. In this study, a similar intervention was given to treatment-resistant CP patients with stressors, relational problems with support partner, and distress, anxiety or depression. Before and 1, 3, and 6 months after the intervention, patients completed the Euro-Qol 5 Dimensions 5 Levels (EQ-5D-5L) and Impact on Participation and Autonomy (IPA) questionnaires (primary outcomes), and the Survey Of Pain Attitudes (SOPA), the Four-Dimensional Symptom Questionnaire (4DSQ) (distress, depression, anxiety, and somatization), and Visual Analog Scale for pain intensity, whereas the support partners completed the Caregiver Strain Index (CSI) questionnaire. Differences between baseline and post-treatment were tested via paired t-tests (significance level 0.05). Of the 39 patients who were included, 34 (87.2%) completed the 3-day treatment. At 1, 3, and 6 months, improvements were seen in EQ-5D-5L-Index (+40.6%; +22.4%; +31.7%), Health Today (+61.8%; +36.3%; +46.8%), Control attitude (+45.8%; not significant [NS]; +55.0%) and decreases in IPA-Problems (−14.8%; NS; −20.4%), Harm attitude (−18.9%; −15.0%; −17.7%), Distress (−17.7%; −31.8%; −37.1%), and Depression (−37.4%; −31.4%; −35.7%) scores. The CSI score had decreased by −29.0%, −21.4%, and −25.9%, respectively. In conclusion, after an intensive 3-day social cognitive intervention, treatment-resistant CP patients experienced substantial and lasting improvements in HRQoL and in problematic limitations to participation and autonomy, in association with improvements in pain attitudes, depression, and distress. To assess whether this innovative approach may be an effective treatment for this subgroup of CP patients, future randomized controlled studies are needed.

Chronic Pain and Selective Attention to Pain Arousing Daily Activity Pictures: Evidence From an Eye Tracking Study

Introduction

According to the pain research literature, attentional bias for pain is the mechanism responsible for the development and maintenance of fear of pain in patients with chronic pain. However, there is still some debate about the exact mechanism and the role of faster engagement versus difficulty in disengagement in the development of attentional bias.

Methods

To investigate attentional bias in patients with chronic pain, we used an eye-tracker with the pictures of pain-provoking activities and compared the results with an age- and gender-matched group of pain-free participants. In addition, other measures of pain-related cognition and pain severity ratings were included to assess their contribution to the attentional bias toward pain-related information.

Results

Calculating the frequency of the first fixations showed that both groups fixated initially on pain-provoking pictures compared to neutral one. Calculating the speed of fixations showed that control participants were faster in fixating on neutral stimuli, but patients with pain were faster in fixating on pain-provoking pictures, indicating a relative vigilance for the pain-related stimuli among them. These patients reported that the intensity of pain in the previous week was positively correlated with the speed of their fixation on the painful stimuli.

Conclusion

Although these results did not provide unequivocal support for the vigilance-avoidance hypothesis, they are generally consistent with the results of studies using eye tracking technology. Furthermore, our findings put a question over characterization of attentional biases in patients with chronic pain by simply relating that to difficulty in disengaging from pain-related stimuli.
