Happy despite pain: Pilot study of a positive psychology intervention for patients with chronic pain

The Effect of Patient Resilience on Postoperative Scores After One- and Two-Level Anterior Cervical Discectomy and Fusion

OBJECTIVE

To investigate the association between resilience and outcomes of pain and neck-related disability after single- and double-level anterior cervical discectomy and fusion (ACDF).

METHODS

Patients who underwent single- or double-level ACDF were sent a survey between 6 months and 2 years after surgery. The survey included the Brief Resilience Scale (BRS), visual analogue scale (VAS) for pain, Neck Disability Index (NDI), and Pain Self-Efficacy Questionnaire (PSEQ-2). Patients completed the VAS and NDI twice, once describing preoperative pain and disability and once describing current pain and disability. Respondents were classified as high resilience (HR), medium resilience (MR), or low resilience (LR). Demographics, PSEQ-2 scores, pre- and postoperative VAS and NDI scores, and change in VAS (ΔVAS) and NDI (ΔNDI) scores were compared between groups.

RESULTS

Thirty-three patients comprised the HR group, 273 patients comprised the MR group, and 47 patients comprised the LR group. All groups demonstrated postoperative improvement in VAS and NDI scores that exceeded previously established MCID values. The HR group demonstrated greater improvement in pain compared with the LR group (ΔVAS: -5.8 for HR vs. -4.4 for LR, P = 0.05). Compared with the MR group, the LR group demonstrated greater postoperative pain (VAS: 3.2 for LR vs. 2.5 for MR, P = 0.02) and disability (NDI: 11.9 for LR vs. 8.6 for MR, P = 0.02).

CONCLUSIONS

Patients demonstrated improvement in pain and neck-related disability after single- and double-level ACDF, regardless of resilience score. Patients with greater resilience may be expected to demonstrate more improvement in pain after ACDF.

Positive psychology interventions can improve mental health for chronic pain patients: a systematic review and meta-analysis

OBJECTIVE

This study examines the efficacy of positive psychology interventions (PPIs) for patients with chronic pain through a systematic review and meta-analysis. PPIs are defined as strategies that involve focusing on positive emotions, thoughts, and behaviors that improve mental health by increasing mental well-being and reducing psychological distress.

DESIGN

The search was conducted using the PubMed, Scopus, PsycINFO, and Cochrane Library databases.

MAIN OUTCOME MEASURES

Subjective, psychological, and social well-being were used as indicators of mental well-being, and depression, anxiety, and stress symptoms were used as indicators of psychological distress. Results: Nine studies were included. Eight studies evaluated subjective well-being, seven evaluated depression, and three evaluated anxiety symptoms. No studies examined psychological well-being, social well-being, or stress. PPIs were found to be effective in promoting subjective well-being post-treatment (Hedges' g = 0.40; 95% CI [0.06, 0.73]) and reducing anxiety (Hedges' g = -0.32, 95% CI [-0.59, -0.06]), but no significant results were found for depression (Hedges' g = -0.23, 95% CI [-0.50, 0.04]).

CONCLUSION

The included investigations, while limited, suggest the utility of PPIs in mitigating the psychological consequences of chronic pain. Researchers and practitioners are encouraged to implement PPI practices.

When It Hurts, a Positive Attitude May Help. The Moderating Effect of Positive Affect on the Relationship Between Walking, Depression, and Symptoms in Women with Fibromyalgia

BACKGROUND

Increased exercise is a marker of health in fibromyalgia (FM). However, patients frequently avoid physical activity as a way of minimizing the pain they feel. This deprives them of opportunities to obtain positive reinforcement, increasing functional impact.

AIMS

This study examines the mediating role of depressive symptoms between walking (as physical exercise), functional impact, and pain, at different levels of positive affect (PA) among women with fibromyalgia.

DESIGN

Cross-sectional correlational study.

SETTINGS

Mutual aid associations for fibromyalgia in Spain.

PARTICIPANTS

231 women diagnosed with FM.

METHODS

Moderate mediation analyses were conducted using PROCESS.

RESULTS

First, a simple mediation model showed that depression mediated the effect of walking on functional impact, but not on pain. Additionally, the moderated mediated model showed that this effect was significant at medium and high levels of PA, but not when levels of PA were low.

CONCLUSIONS

Provision of resources focused on positive affect seem to increase the positive effects of walking on functional impact through the reduction of depressive symptoms. Nurses can improve adherence of patients with FM to walking behavior through increasing positive affect.

The Influence of the Fear of Negative Evaluation on Activity Avoidance in Fibromyalgia: Exploring Pain Acceptance and Positive Affect as Resilience Variables

To examine the mediating role of pain acceptance (PAcc) between fear of negative evaluation (FNE) and activity avoidance (AV) at different levels of positive affect (PA) (moderator) among women diagnosed with fibromyalgia (FM) (moderate mediation model). This study was cross-sectional in design. A convenience sample of women with FM (n = 231) completed measures of pain severity, FNE, PAcc, AV, and PA. A simple mediation model and a moderate mediation model was constructed and analyzed using the SPSS macro-PROCESS. First, PAcc mediated the effect of FNE on AV (β = .02, SE = 0.008; [95% CI [0.0075, 0.0394]). Second, a mediated effect of PAcc between FNE and AV moderated by PA at medium and high levels of PA were found (m: 0.23; β = -.22, p = .0006; h: 9.59; β = -.34, p = .0002. Future work should seek to validate study findings in diverse samples of FM patients. Additionally, future work should explore how FM self-management interventions that include PAcc can promote increased activity among women suffering from FM with medium to high levels of PA.

Adaptability and Resilience in Aging Adults (ARIAA): protocol for a pilot and feasibility study in chronic low back pain

Background

Chronic low back pain (cLBP) is the leading cause of disability among older adults and one of the top reasons for seeking healthcare, resulting in significant decrements in physical functioning. Because older adults are among the fastest growing cohorts in the USA, both the incidence and burden of cLBP are expected to increase considerably, rendering geriatric pain management a top health priority. Resilience is defined as a process allowing individuals to adapt and recover from adverse and stressful conditions, and it has been highlighted as a crucial factor in positive health-related functioning. While a growing body of literature supports the use of resilience-based interventions in chronic pain, research examining their effectiveness in older adults with cLBP remains limited. The primary aims of the study are to assess the feasibility and acceptability of a psychologically oriented resilience intervention among aging adults with cLBP.

Methods

In this article, we describe the rationale and design of the Adaptability and Resilience in Aging Adults (ARIAA) study, a single-arm intervention in which 60 participants (ages ≥ 60 years) with cLBP will be recruited to participate in a 7-week group-based program aimed at enhancing psychological resilience. Intervention sessions will target positive psychology concepts (e.g., positive affect, pain acceptance, hopeful thinking, pain self-efficacy) and cognitive behavioral techniques that have established benefits in pain management. Primary study outcomes include intervention feasibility and acceptability as measured by treatment engagement, intervention credibility and satisfaction, ability to meet recruitment and retention metrics, and the feasibility of questionnaire and home activity completion. Outcomes will be assessed at baseline, immediately at posttreatment, and at the 3-month follow-up period.

Discussion

This study will establish the feasibility and acceptability of a novel intervention aimed at enhancing positive, psychological functioning, and resilience in older adults with cLBP. Achievement of these aims will provide a rich platform for future intervention research targeting improvements in pain and disability among geriatric populations and will serve as a foundation for a fully powered trial to examine treatment efficacy of the proposed intervention.

Pain psychology in the 21st century: lessons learned and moving forward

Background and aims In the spring of 2019, Professor Steven J. Linton, the founder of the Center for Health and Medical Psychology (CHAMP) at Örebro University, Sweden, formally retired. As a tribute to his scholarly work covering decades of influence and inspiration to the field of pain psychology, the research center organized a topical conference titled "Pain in the 21st century: Where do we come from and where are we going?", which resulted in this state-of the-art synthesis. The aim of this declaration is to highlight lessons learned but not in the least is meant to inspire and guide our continued journey forward, developing pain psychology into the 21st century. Methods Several collaborators of Professor Linton have summarized and reflected on the current state-of-the-art of pain psychology from the perspective of his input to the field, as well as on developments from the last years of advancements in pain psychology. Results The topics have been divided into six themed sections covering the fear avoidance model, transdiagnostics, secondary prevention, risk- and protective factors, communication and contextual factors. The sections cover a broad spectrum, from basic experimental studies, integrating emotion and motivational theories into current theoretical models, to applied research on the effect of early interventions as well as sophisticated emotion-focused treatment models for pain patients with concurrent emotional ill-health. Conclusions There have been major advancements within pain psychology research during the last decades, moving the field towards a more comprehensive picture, taking emotional and motivational aspects into account to understand pain sufferers. Although psychologically informed interventions in general mainly focus on the individual, it has been put forward that pain management is highly influenced by the surrounding environment, including communication with health care providers, and the occupational and social context. Implications Professor Steven J. Linton has been at the forefront of pain psychology research during the last decades, and inspired by his work this journey will continue into the 21st century, with the ultimate goal of enhancing the understanding and treatment for all people suffering from persistent and disabling pain.

A Systematic Review of Self-Compassion in Chronic Pain: From Correlation to Efficacy

Chronic pain (CP) is a common condition affecting millions of people worldwide. Compassion-related interventions are proving to be advantageous in CP, and self-compassion (SC) is hypothesized to be related with pain regulation physiological processes, as well as with psychological benefits in CP. We aimed to review scientific literature on: 1) Compassion-based psychological interventions and their changes in pain outcomes; and 2) associations between SC and pain-related outcomes. We performed a systematic research in four electronic databases: MEDLINE, EMBASE, PsycINFO and the Cochrane Library from inception until April 2020. In Question 1, we included studies involving adult patients with CP who participated in compassion-based psychological interventions. In Question 2, we included studies that examined the associations between SC and pain outcomes in adults with CP. We identified 16 studies. For Question 1, we included seven studies focused on different compassion-based interventions that assessed at least one pain outcome, in a total of 253 participants with CP associated with multiple conditions. For Question 2, we included nine studies, in a total of 1,430 participants, with eight different pain outcomes: Intensity, acceptance, catastrophizing, self-efficacy, disability, distress, pain related coping and anxiety. Considering the high heterogeneity between studies and the poor-quality assessment, we could not draw definitive conclusions on the efficacy of compassion-based interventions nor on the association between SC and pain outcomes. Studies are further discussed in detail. This review can be a starting point for large-scale and high-quality trials in this area as it provides an organized overview of the current literature on this topic.

Bouncing back after lumbar spine surgery: early postoperative resilience is associated with 12-month physical function, pain interference, social participation, and disability

BACKGROUND CONTEXT

Positive psychosocial factors early after surgery, such as resilience and self-efficacy, may be important characteristics for informing individualized postoperative care.

PURPOSE

To examine the association of early postoperative resilience and self-efficacy on 12-month physical function, pain interference, social participation, disability, pain intensity, and physical activity after lumbar spine surgery.

STUDY DESIGN/SETTING

Pooled secondary analysis of prospectively collected trial data from two academic medical centers.

PATIENT SAMPLE

Two hundred and forty-eight patients who underwent laminectomy with or without fusion for a degenerative lumbar condition.

OUTCOME MEASURES

Physical function, pain inference, and social participation (ability to participate in social roles and activities) were measured using the Patient Reported Outcomes Measurement Information System. The Oswestry Disability Index, Numeric Rating Scale, and accelerometer activity counts were used to measure disability, pain intensity, and physical activity, respectively.

METHODS

Participants completed validated outcome questionnaires at 6 weeks (baseline) and 12 months after surgery. Baseline positive psychosocial factors included resilience (Brief Resilience Scale) and self-efficacy (Pain Self-Efficacy Questionnaire). Multivariable linear regression analyses were used to assess the associations between early postoperative psychosocial factors and 12-month outcomes adjusting for age, sex, study site, randomized group, fusion status, fear of movement (Tampa Scale for Kinesiophobia), and outcome score at baseline. This study was funded by Patient-Centered Outcomes Research Institute and Foundation for Physical Therapy Research. There are no conflicts of interest.

RESULTS

Resilience at 6 weeks after surgery was associated with 12-month physical function (unstandardized beta=1.85 [95% confidence interval [CI]: 0.29; 3.40]), pain interference (unstandardized beta=-1.80 [95% CI: -3.48; -0.12]), social participation (unstandardized beta=2.69 [95% CI: 0.97; 4.41]), and disability (unstandardized beta=-3.03 [95% CI: -6.04; -0.02]). Self-efficacy was associated with 12-month disability (unstandardized beta=-0.21 [95% CI: -0.37; -0.04].

CONCLUSIONS

Postoperative resilience and pain self-efficacy were associated with improved 12-month patient-reported outcomes after spine surgery. Future work should consider how early postoperative screening for positive psychosocial characteristics can enhance risk stratification and targeted rehabilitation management in patients undergoing spine surgery.

The effect of optimism on the facial expression of pain: Implications for pain communication

BACKGROUND

There is a broad range of evidence on optimism dampening the pain experience, as assessed by subjective self-report. Facial expression of pain conveys supplementary information about the pain experience, is an integral part of pain communication and assists psychosocial pain coping. Nevertheless, the effect of induced optimism on facial activity during pain has to our knowledge not been examined.

METHODS

In our experiment, 40 healthy participants underwent two blocks of thermal stimulation containing phasic non-painful and painful stimuli. Between the two blocks, the Best Possible Self imagery and writing task was performed to induce situational optimism, while a control group wrote about their typical day. Facial activity and self-report ratings of intensity and unpleasantness were recorded. Facial activity was analysed using the Facial Action Coding System.

RESULTS

The optimism manipulation was successful in increasing state optimism. It did not affect self-report ratings, but resulted in a stronger facial expression of pain, caused especially by increases in Action Units 4 (furrowed brows) and 6_7 (narrowed eyes).

CONCLUSIONS

All Action Units, which were affected by the optimism induction, are known to be prevalent during pain stimulation. The increase in facial expression might reflect reduced inhibition of pain communication in temporarily optimistic participants. Optimism might lead to expecting positive and helpful reactions from others and, by that, to great readiness to elicit these reactions by non-verbal social behaviour.

SIGNIFICANCE

This study is the first to indicate that state optimism increases the facial expression of pain as a social signal for help and empathy without concomitant changes in the subjective pain experience.

Psychosocial Correlates of Objective, Performance-Based, and Patient-Reported Physical Function Among Patients with Heterogeneous Chronic Pain

BACKGROUND

Improving all aspects of physical function is an important goal of chronic pain management. Few studies follow recent guidelines to comprehensively assess physical function via patient-reported, performance-based, and objective/ambulatory measures.

PURPOSE

To test 1) the interrelation between the 3 types of physical function measurement and 2) the association between psychosocial factors and each type of physical function measurement.

METHODS

Patients with chronic pain (N=79) completed measures of: 1) physical function (patient-reported disability; performance-based 6-minute walk-test; objective accelerometer step count); 2) pain and non-adaptive coping (pain during rest and activity, pain-catastrophizing, kinesiophobia); 3) adaptive coping (mindfulness, general coping, pain-resilience); and 4) social-emotional dysfunction (anxiety, depression, social isolation and emotional support). First, we tested the interrelation among the 3 aspects of physical function. Second, we used structural equation modeling to test associations between psychosocial factors (pain and non-adaptive coping, adaptive coping, and social-emotional dysfunction) and each measurement of physical function.

RESULTS

Performance-based and objective physical function were significantly interrelated (r=0.48, p<0.001) but did not correlate with patient-reported disability. Pain and non-adaptive coping (β=0.68, p<0.001), adaptive coping (β=-0.65, p<0.001) and social-emotional dysfunction (β=0.65, p<0.001) were associated with patient-reported disability but not to performance-based or objective physical function (ps>0.1).

CONCLUSION

Results suggest that patient-reported physical function may provide limited information about patients' physical capacity or ambulatory activity. While pain and non-adaptive reactions to it, adaptive coping, and social-emotional dysfunction may potentially improve patient-reported physical function, additional targets may be needed to improve functional capacity and ambulatory activity.

Optimism and the Experience of Pain: A Systematic Review

A growing body of literature provides evidence of the health-promoting effects of optimism, including its protective role in acute and chronic pain. Optimists are characterized by positive expectations concerning the future. These positive outcome expectancies lead to more and longer goal-directed efforts and the use of approach coping strategies. No systematic review on the effects of optimism on the experience of pain has so far been conducted. A search in the databases PubMed, Web of Science and PsycInfo, and the scanning of reference lists identified 69 eligible studies. These were categorized according to sample size, participants' age and sex, design, optimism-pain relation as primary vs. secondary study objective, and level of study/publication quality. Overall percentages of positive, zero, and negative associations between optimism and pain as well as relative frequencies of these associations in the different categories were analyzed. About 70% of the studies showed a positive, i.e., beneficial association between optimism and at least one pain outcome. A larger percentage of beneficial associations was found in studies with experimental designs, in studies with the optimism-pain relation as primary objective, in high-quality studies/publications, and in studies including participants with a higher average age. The review suggests that optimism is associated with less acute and chronic pain, especially since a higher percentage of beneficial associations was found with high study/publication quality and with the primary focus on this relationship. For the moderating role of age, different explanations are proposed. Further research on causal relationships and on optimism-fostering clinical interventions is needed.

The Effects of Positive Psychological Interventions on Medical Patients' Anxiety: A Meta-analysis

OBJECTIVE

Positive psychology interventions, which involve systematic completion of activities designed to promote well-being, are being increasingly studied in medically ill patients. However, the extent to which these interventions ameliorate patient anxiety remains unclear. Therefore, the aim of the study was to conduct a meta-analysis to determine the efficacy of positive psychology interventions in reducing anxiety in medical patients.

METHODS

Electronic databases Medline, PsycINFO, SciELO, Cochrane (Central), and ClinicalTrials.gov were searched from inception to June 18, 2018, to identify studies of positive psychology interventions that included a validated measure of anxiety as an outcome measure.

RESULTS

The search generated a total of 1024 studies. Twelve randomized controlled trials (n = 1131) delivered to medical patients were included in the review, and a further 11 nonrandomized trials (n = 300) were included in a secondary analysis. Positive psychology interventions were effective at reducing patient anxiety relative to a control with a small to medium effect size (g = -0.34, 95% confidence interval = -0.50 to -0.18), and results were maintained at a mean of 8-week follow-up (g = -0.31, 95% confidence interval = -0.54 to -0.08). Clinician-led interventions seemed to be more effective than self-administered interventions, and longer interventions were more effective than shorter interventions. Secondary analysis of nonrandomized trials also found that positive psychology interventions are associated with reduced anxiety.

CONCLUSIONS

Positive psychology interventions seem to be effective at reducing medical patient anxiety. Future research is needed to determine optimal intervention characteristics, including dose and intervention content, that maximize the observed treatment effects.

Optimizing resilience in orofacial pain: a randomized controlled pilot study on hope

Introduction:

Over recent years, there has been growing interest in the role of positive, psychological resources that promote resilience and optimal functioning in chronic pain. Although multiple factors comprise resilience, hope is a strength-based motivational state known to contribute to positive psychosocial adjustment and adaptive pain coping. Emerging evidence supports the viability of therapeutic approaches that foster resilience; however, interventions designed to target hope in the context of pain have been remarkably understudied.

Objectives:

The objectives of this pilot study were to test the feasibility and preliminary efficacy of a resilience-oriented hope intervention for clinical pain, as well as psychosocial outcomes and experimental pain sensitivity in individuals with orofacial pain.

Methods:

Twenty-nine participants with temporomandibular disorder were randomized to a 3-session intervention intended to increase hope or a control intervention (EDU) involving education about pain and stress. Before and after the intervention, participants attended 2 laboratory sessions whereby they completed psychosocial questionnaires and sensitivity to heat, cold, and pressure pain was assessed. Hope was measured using the Adult State Hope Scale.

Results:

Compared with EDU, the Hope group exhibited an increase in state hope, lower heat pain sensitivity, higher pressure pain thresholds at the temporomandibular joint, and reductions in pain catastrophizing.

Conclusion:

Although preliminary, results suggest that a resilience-based hope intervention may be beneficial in reducing pain sensitivity and catastrophizing and could serve as a target for pain management.

Mindful Learning Improves Positive Feelings of Cancer Patients' Family Caregivers

Positive feelings are an important health dimension for family caregivers of cancer patients. The aim of this study was to investigate whether Langerian mindfulness is a valid proactive method to increase the positive feelings of family caregivers for cancer patients. Participants were randomly assigned to either a mindfulness group or a mindlessness group and completed the Caregiver Reaction Assessment (CRA) as a measure of caregivers' feelings before the intervention. Subsequently, both groups were given four sessions of mindfulness training using "innovation classification". Finally, participants completed the Langer Mindfulness Scale (LMS) and the Positive Aspects of Caregiving (PAC) scale as post-intervention measures. The results revealed that participants in the mindfulness and mindlessness groups differed significantly in LMS and PAC scores, with the mindfulness group having higher levels of positive feelings than those in the mindlessness group. The results also indicated that mindfulness level significantly predicted positive feelings of caregivers. Thus mindful interventions may play a meaningful role in promoting family caregivers' spirituality and faith, improving the willingness of sharing their thoughts, beliefs, and grief, which could be useful for increasing the positive feelings of caregivers.

[Psychological factors predictive of healthy lifestyles]

OBJECTIVE

To present a robust statistical model that considers some psychological factors as predictors of healthy lifestyle.

MATERIALS AND METHODS

A battery composed of validated instruments was applied to evaluate beliefs, healthy practices, coping styles, positive mental health and perceived self-efficacy in a sample of 570 university students from Bogotá, Colombia. Based on the information obtained, descriptive, variance and correlation analyzes were developed, as well as a structural equations model.

RESULTS

High scores were obtained in the categories 'optimal psychological factors', 'beliefs and healthy practices', except for the 'physical activity practice' and 'less adaptive coping factors' categories. Likewise, significant differences were found in most of the variables measured, as well as important correlations between adaptive psychological factors and healthy practices and beliefs. Finally, the structural equations model that showed the greatest adjustment predicts by 89% the variance of positive mental health based on the interaction between the variables 'coping directed to the problem', 'general satisfaction', 'pro social attitude', 'social skills' and 'self-efficacy'. In turn, the presence of positive mental health, when interacting with healthy beliefs, predicts the occurrence of healthy lifestyles by 63%.

CONCLUSION

Even when the model is not conclusive, it can provide empirical support to possible health interventions to be implemented in higher education institutions, based on the strengthening of psychological predictive factors.

Happy Despite Pain: A Randomized Controlled Trial of an 8-Week Internet-delivered Positive Psychology Intervention for Enhancing Well-being in Patients With Chronic Pain

Supplemental Digital Content is available in the text.

Objectives:

There is preliminary evidence for the efficacy of positive psychology interventions for pain management. The current study examined the effects of an internet-based positive psychology self-help program for patients with chronic musculoskeletal pain and compared it with an internet-based cognitive-behavioral program.

Materials and Methods:

A randomized controlled trial was carried out with 3 conditions: an internet-delivered positive psychology program, an internet-delivered cognitive-behavioral program and waitlist control. A total of 276 patients were randomized to 1 of the 3 conditions and posttreatment data were obtained from 206 patients. Primary outcomes were happiness, depression, and physical impairments at posttreatment and at 6-month follow-up. Intention-to-treat analyses were carried out using mixed regression analyses.

Results:

Both treatments led to significant increases in happiness and decreases in depression. Physical impairments did not significantly decrease compared with waitlist. Improvements in happiness and depression were maintained until 6-month follow-up. There were no overall differences in the efficacy of the 2 active interventions but effects seemed to be moderated by education. Patients with a higher level of education profited slightly more from the positive psychology intervention than from the cognitive-behavioral program.

Discussion:

The results suggest that an internet-based positive psychology and cognitive-behavioral self-help interventions for the management of chronic pain are clinically useful. Because the self-help exercises as used in the current program do not require therapist involvement, dissemination potential is large. Further studies should examine whether it can best be used as stand-alone or add-on treatment combined with established pain treatment programs.

Pain catastrophizing mediates the relationship between trait happiness and depressive symptoms in individuals with current pain

OBJECTIVE

There is an extensive relationship between chronic pain and depression; however, there is less research examining whether pain-specific factors, such as pain intensity, predict depression, above and beyond the role of normative factors, such as positive emotions. The current study characterized the independent contributions of pain intensity, pain catastrophizing, and a trait measure of happiness to self-rated depressive symptoms.

METHODS

We recruited and enrolled 70 volunteers across 3 groups of participants: two groups of patients with current low back pain (one group on opioids and one group opioid-naïve), and individuals in a methadone maintenance treatment program.

RESULTS

Of note, participants reporting concurrent opioid use reported significantly higher levels of depressive symptomatology, although study groups did not differ on any other clinical variables. In our path model, we failed to find direct relationships between pain (intensity or duration) and either trait happiness or depressive symptoms (p > .05). However, our analysis did reveal that individuals with chronic back pain who reported higher levels of trait happiness reported lower levels of depressive symptomatology; this effect was significantly mediated by lower levels of pain catastrophizing (standardized ab = -.144, p = .002).

CONCLUSION

Our analysis suggests that trait happiness, while unrelated to ongoing pain, may predict a decreased vulnerability to depressive symptoms in individuals with chronic pain, which may operate via lower levels of pain catastrophizing.

Affect and Low Back Pain: More to Consider Than the Influence of Negative Affect Alone

OBJECTIVES

Affect balance style, a measure of trait positive affect (PA) and negative affect (NA), is predictive of pain and functioning in fibromyalgia and healthy individuals. The purpose of this study was to evaluate the distribution of affect balance styles and the relationship between these styles and clinical factors in low back pain.

METHODS

In this cross-sectional study, patients with low back pain (N=443) completed questionnaires and were categorized as having 1 of 4 distinct affect balance styles: Healthy (high levels of PA and low levels of NA), Low (low PA/low NA), Reactive (high PA/high NA), and Depressive (low PA/high NA). Comparisons between groups were made in regard to pain, functioning, and psychiatric comorbidity.

RESULTS

High NA was observed in 63% (n=281), whereas low PA was present in 81% (n=359). We found that having a Depressive style was associated with greater pain severity, increased odds for comorbid fibromyalgia, and worse functioning compared with having a Healthy or Low style. Yet, those with a Low style were at increased risk for depression compared with a Healthy style, whereas patients with a Reactive style had similar levels of pain, functioning, and depression as those with a Healthy affective style.

CONCLUSIONS

Our study revealed that there are important differences between trait affect balance styles in regard to pain, mood, and functioning in low back pain. Findings related to Reactive and Low affective styles suggest that relationships between affect, pain, and disability in low back pain extend beyond considering NA alone.

Calidad de vida, emociones negativas, autoeficacia y calidad del sueño en pacientes con dolor crónico: efectos de un programa de intervención psicológica

El dolor crónico es un problema de salud que afecta a entre el 10 y el 30% de la población. El objetivo del presente estudio consiste en evaluar la eficacia de un programa de intervención grupal en dolor crónico. Se realizó un estudio cuasi experimental. La muestra estuvo compuesta por 105 participantes de la Unidad de Dolor del Hospital General Universitario de Alicante. Se administró una batería de cuestionarios pre y post a la aplicación del programa. En el estudio se midió el nivel de dolor, la calidad de vida, ansiedad, depresión, atributos del sueño y autoeficacia. Se obtuvieron mejoras significativas en los niveles de ansiedad, depresión calidad de vida física, autoeficacia en todas sus dimensiones (control de síntomas, funcionamiento físico y control del dolor) y aspectos de los atributos del sueño, como cantidad y alteraciones del sueño. El programa protocolizado y realizado por profesionales entrenados es efectivo para disminuir la percepción del dolor, aumentar la calidad de vida en su componente físico, mejorar la autoeficacia y los atributos del sueño en pacientes con dolor crónico.

Can positive affect attenuate (persistent) pain? State of the art and clinical implications

Purpose of Review

Pain is an intense experience that can place a heavy burden on peoples’ lives. The identification of psychosocial risk factors led to the development of effective pain treatments. However, effect sizes are modest. Accumulating evidence suggests that enhancing protective factors might also impact on (well-being despite) pain. Recent findings on positive affect (interventions) towards pain-related outcomes will be reviewed, and new avenues for treatment of persistent pain will be discussed.

Recent Findings

Positive affect significantly attenuates the experience of pain in healthy and clinical populations. Positive affect interventions effectively reduce pain sensitivity and bolster well-being despite pain. Through both psychological and (neuro-)biological pathways, but also through its effect on central treatment processes such as inhibitory learning, positive affect can optimize the efficacy of existing treatments.

Summary

Comprehensive understanding of the unique roles and dynamic interplay of positive and negative affect in moderating pain may optimize the treatment of (persistent) pain.

Towards a science and practice of resilience in the face of pain

The primary objective of this paper is to discuss how a resilience approach to (chronic) pain may advance our current understanding of (mal)adaptation to pain. Different resilience perspectives are described, and future challenges for research, prevention and treatment of (chronic) pain are discussed. Literature searches were performed in Web of Science and PubMed to identify relevant literature on risk and resilience in the context of pain. Resilience can be best defined as the ability to restore and sustain living a fulfilling life in the presence of pain. The Psychological Flexibility Model, the Broaden-and-Build Theory, and Self-Determination Theory are described as theories that may provide insight into resilience within the context of (chronic) pain. We describe how a resilience paradigm shifts the outcomes to pursue in pain research and intervention and argue the need for including positive outcomes in addition to negative outcomes. Psychological flexibility, positive affect and basic psychological needs satisfaction are described as potentially important resilience mechanisms with the potential to target both sustainability and recovery from pain. A resilience approach to chronic pain may have important implications for the prevention and treatment of chronic pain problems, as it may give specific indications on how to empower patients to continue living a fulfilling life (in the presence of pain).

SIGNIFICANCE

The resilience approach put forward in this review spotlights sustainability of positive outcomes (e.g. engagement in meaningful activities) in the presence of pain as an outcome to pursue beyond recovery of negative outcomes. We illuminate the evidence-base and practical application of promising resilience mechanisms (positive emotions, psychological flexibility, needs satisfaction). For this article, a commentary is available at the Wiley Online Library.

Social pain and physical pain: shared paths to resilience

Although clinical models have traditionally defined pain by its consequences for the behavior and internal states of the sufferer, recent evidence has highlighted the importance of examining pain in the context of the broader social environment. Neuroscience research has highlighted commonalities of neural pathways connecting the experience of physical and social pain, suggesting a substantial overlap between these phenomena. Further, interpersonal ties, support and aspects of the social environment can impair or promote effective adaptation to chronic pain through changes in pain perception, coping and emotional states. The current paper reviews the role of social factors in extant psychological interventions for chronic pain, and discusses how greater attention to these factors may inform future research and clinical care.
