Understanding Co-occurring Emotion and Pain: The Role of Context Sensitivity from a Transdiagnostic Perspective

Catastrophizing and rumination mediate the link between functional disabilities and anxiety/depression in fibromyalgia. A double-mediation model

Fibromyalgia can be considered to be a model of chronic pain resulting from dysregulation of pain processing. From a psychological point of view, it is possible to consider transdiagnostic processes that would participate in both the dysregulation of pain and associated emotions.

OBJECTIVE

The aim of this study was to test the links that exist between the tendency to Repetitive Negative Thinking (RNT) and the anxious-depressive manifestations in fibromyalgia. More specifically, we wanted to test a double mediation model where RNT would mediate the link between pain and depression/anxiety via catastrophizing.

METHOD

Eighty-two patients with fibromyalgia completed a series of questionnaires evaluating their level of depression, anxiety, disability related to pain, catastrophizing as well as various measures of Repetitive Thoughts.

RESULTS

The results showed strong correlations between RNT levels, pain, and anxious-depressive manifestations in this population. Moreover, the links between pain and depression/anxiety were mediated by catastrophizing and RNT in serial.

CONCLUSION

Results support the interest of studying RNT as a transdiagnostic process in fibromyalgia pain. Considering RNT in fibromyalgia allows a better understanding of tthe links that exist between pain and emotional disorders in this population and thus to better understand the psychopathological comorbidity of fibromyalgia.

Effect of stress on contextual pain sensitivity in the preoperative period- A proof of concept study

Background and Aims

The importance of non-noxious contextual inputs in the interplay of pain with neurophysiologic and behavioral factors is gaining recognition. Stress of impending surgery can act as a negative context, leading to a decrease in pain threshold in patients. This study was conducted to assess the influence of stress conferred by the imminent and other contextual inputs such as anxiety, socioeconomic status, prior painful experience, and the effect of gender on modulation of pain perception in patients undergoing elective surgery.

Material and Methods

In total, 120 patients aged between 18 and 60 years of either gender posted for elective gastrointestinal surgery under general anesthesia were recruited. Data were collected on preoperative anxiety level, socioeconomic status, education, and any prior painful experience. A pressure algometer was used to measure the pressure pain thresholds and pain tolerance on the day before surgery and on the morning of surgery in the preoperative suite.

Results

There was a statistically significant decrease in both pain threshold (P < 0.0001) and pain tolerance in the immediate preoperative period in comparison to the baseline readings taken the day before surgery (P = 0.048). The magnitude of change in pain scalars was greater in females (P < 0.001), those with a high anxiety score, and a history of severe painful experience in the past.

Conclusion

Preoperative surgical stress lowers the pain threshold and pain tolerance. Contextual modulation of pain by factors such as anxiety and memory of prior painful experience, especially in the female gender, could influence postoperative patient outcomes and warrants further research.

Study protocol and methods for Easing Pelvic Pain Interventions Clinical Research Program (EPPIC): a randomized clinical trial of brief, low-intensity, transdiagnostic cognitive behavioral therapy vs education/support for urologic chronic pelvic pain syndrome (UCPPS)

Background

Urologic chronic pelvic pain syndrome (UCPPS) encompasses several common, costly, diagnoses including interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome that are poorly understood and inadequately treated with conventional medical therapies. Behavioral strategies, recommended as a first-line treatment for managing symptoms, are largely inaccessible, time and labor intensive, and technically complex. The Easing Pelvic Pain Interventions Clinical Research Program (EPPIC) is a clinical trial examining the efficacy of low-intensity cognitive behavioral therapy (Minimal Contact CBT or MC-CBT) for UCPPS and its durability 3 and 6 months post treatment. Additional aims include characterizing the operative processes (e.g., cognitive distancing, context sensitivity, coping flexibility, repetitive negative thought) that drive MC-CBT-induced symptom relief and pre-treatment patient variables that moderate differential response.

Methods

UCPPS patients (240) ages 18–70 years, any gender, ethnicity, and race, will be randomized to 4-session MC-CBT or a credible, non-specific education comparator (EDU) that controls for the generic effects from simply going to treatment. Efficacy assessments will be administered at pre-treatment, 2 weeks, and 3 and 6 months post treatment-week acute phase. A novel statistical approach applied to micro-analytic mediator assessment schedule will permit the specification of the most effective CBT component(s) that drive symptom relief.

Discussion

Empirical validation of a low-intensity self-management therapy transdiagnostic in scope has the potential to improve the health of chronic pelvic pain patients refractory to medical therapies, reduce social and economic costs, conserve health care resources, as well as inform evidence-based practice guidelines. Identification of change mechanisms and moderators of treatment effects can provide proactive patient-treatment matching fundamental to goals of personalized medicine.

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.

Understanding suicidal ideation and behaviour in individuals with chronic pain: a review of the role of novel transdiagnostic psychological factors

Individuals with chronic pain are at an elevated risk of suicide, yet psychosocial factors that might be involved in increasing or decreasing vulnerability for suicidal ideation and behaviour have received little attention. Extant literature on the topic of suicide in individuals with chronic pain incorporates only a few of the wide array of known vulnerability and protective factors. This Review focuses on transdiagnostic psychological processes, (ie, those of relevance for both chronic pain and suicide). We reviewed a selection of published literature on chronic pain and suicide, concentrating on previously unexplored and underexplored lines of research, including future orientation, mental imagery, and psychological flexibility. A greater degree of crosspollination between the fields of chronic pain and suicide research is required to progress our understanding of why some people with chronic pain become suicidal and others do not.

The mechanisms of pain tolerance and pain-related anxiety in acute pain

This study emphasizes the role of pain catastrophizing and state anxiety on pain tolerance and pain-related anxiety. Response expectancies for pain tolerance and pain intensity were tested as potential mediators. A cold-pressor task was used on a healthy sample. Measures were taken before and after cold-pressor procedure, while aversive versus neutral information regarding the cold-pressor task was given prior to the pain induction. An exploratory path model was conducted. Similar paths for pain tolerance and for pain-related anxiety were shown in aversive condition. Also, psychological measures may explain pain experience in aversive context.

"When I feel the worst pain, I look like shit" - body image concerns in persistent pain

Background and aims Persistent pain is a pervasive condition that is often associated with a distorted body image. Most research into pain and body image investigated neural or physiological correlates (e.g. phantom limb pain), and much less is known about the psychological experience of body image changes in response to pain such as appearance concerns. The aim was to examine body image concerns in people with persistent pain, in particular appearance concerns and related coping behaviours and appearance-related emotions such as anger and shame. Methods Design was cross-sectional and data was collected through in-depth semi-structured interviews with people suffering from persistent musculoskeletal pain (n=7; six females; age=19-56), and analysed with inductive thematic analysis (TA). Results Two main themes were identified: "Relationship to the painful body" and "Dissatisfaction with the body", each containing three subthemes, along with the side-theme "Appearance concerns affected by pain and mood". All participants reported appearance concerns, predominantly about their weight and related coping behaviours such as avoidance of mirrors, exercising or dieting and pain-induced mood changes that were associated with a negative body image. Conclusions People with persistent pain report appearance concerns, often related to pain-induced negative mood changes, and reduced functioning. It remains unclear to what extent attitudes towards the body change over time in accordance with pain. A wider concept of body image is required, including the perception of reduced functioning, related appraisals (e.g. "I look weak and old") and appearance investment.

Responding to social cues: An experimental paradigm exploring the link between context sensitivity and pain

Objectives

The term context sensitivity refers to whether a response is in tune with the ever changing demands of the context, while insensitivity is the lack of responding to these cues. To date, we know little about how well patients with pain respond emotionally to changes in the cues provided by the social context, that is, how emotionally context (in)sensitive they are and if this is related to problem severity. The aim of this experimental study was to test a method for determining levels of context sensitivity in individuals with subacute and chronic pain and to explore the link between context (in)sensitivity and pain‐related problems. We operationalized context (in)sensitivity as participants’ emotional responses (observed facial expressions and self‐reported affect) and pain bothersomeness in these contexts and explored the association between these context‐(in)sensitive social‐emotional responses and pain‐related problems.

Methods

Sixty‐two participants with pain were cued to talk openly about three different topics consecutively in a counterbalanced order: (1) their pain, (2) a negative non‐pain topic, and (3) a positive non‐pain topic. We measured the participants’ emotional responses (observed facial expressions and self‐reported affect) and pain bothersomeness across these contexts and explored the effect of social‐emotional responding on pain‐related problems.

Results

The results showed that, irrespective of individuals’ baseline levels of pain bothersomeness, positive affect, and negative affect, those who reacted with more negative affect and pain bothersomeness when prompted to discuss a positive topic had higher levels of pain‐related problems. Moreover, those who showed more negative facial expressions and pain bothersomeness when prompted to discuss a negative non‐pain topic also had higher levels of pain‐related problems.

Conclusions

These findings highlight a link between sensitivity to the social context and the severity of a pain problem. We showed that individuals with greater problem severity were less sensitive to social cues in their emotional responses, as compared to individuals with less pain‐related problems. As predicted, context‐insensitive responding appears to be most strongly associated with pain‐related problems when dealing with negative emotions. Although the cross‐sectional nature of the study prohibits causal conclusions, our findings demonstrate a link and future research is clearly needed to unravel the role of context sensitivity in the development of pain over time.

An mHealth Intervention for Persons with Diabetes Type 2 Based on Acceptance and Commitment Therapy Principles: Examining Treatment Fidelity

Background

Web-based interventions are becoming an alternative of treatment aimed to support behavioral changes and several advantages over traditional treatments are reported. New ways of delivering an intervention may result in new challenges regarding monitoring of treatment fidelity (TF) which is essential to ensure internal and external validity. Despite the importance of the theme, only a few studies in this field are reported.

Objective

To examine TF of a mobile phone delivered intervention based on Acceptance and Commitment Therapy (ACT) with electronic diaries and written situational feedback for persons with diabetes mellitus type 2, the recommendations from the Behavior Change Consortium (BCC) established by The National Institutes of Health (NHI) were applied. To analyze fidelity, they recommend 5 areas to be investigated (1) design of the study, (2) provider training, (3) delivery of treatment, (4) receipt of treatment, and (5) enactment of treatment. In the current study, these areas were examined based on the analysis of therapists’ adherence to the treatment protocol and participants’ and therapists’ experience with the intervention.

Methods

To investigate the therapists’ adherence to the treatment protocol, a total of 251 written feedback text messages were divided into text segments. Qualitative thematic analyses were then performed to examine how ACT and other therapeutic processes were used in the feedback by the therapists. For the therapists’ and participants’ experience analysis, participants answered a self-reported questionnaire and participated in 2 interviews. The therapists continuously reported their experiences to the researcher responsible for the project.

Results

The results show high adherence to the TF strategies 20/21 (95%) applicable items of the fidelity checklist recommended by NHI BCC were identified in the present study. Measured provider skill acquisition post-training was the only item absent in the fidelity checklist. The results also show high therapists’ adherence to the treatment protocol. All ACT processes (values, committed action, acceptance, contact with the present moment, self as context and cognitive defusion) were found in the coded text segments of the feedback in addition to communication and motivation strategies. For 336/730 (46%) of total possible text segments coded independently by 2 researchers, the interrater reliability measured by Cohen’s kappa was .85. The evaluation of participants’ and therapists’ experience with the intervention was generally positive.

Conclusions

Based on the analyses of therapists’ adherence to the treatment protocol grounded by ACT-principles and participants’ and therapists’ experience with the intervention, the 5 areas of TF recommended by NHI BCC were analyzed indicating a high level of TF. These results ensure an appropriate level of internal and external validity of the study and reliable intervention results and facilitate a precise replication of this intervention concept. Web-based psychological interventions to support people with chronic conditions are becoming increasingly more common. This study supports the results from a previous study which indicated that ACT could be reliably delivered in a written web-based format.

Understanding the Etiology of Chronic Pain From a Psychological Perspective

The etiology of chronic pain-related disability is not fully understood, particularly from a clinical perspective. Investigations to date have identified risk factors and elucidated some important processes driving the development of persistent pain problems. Yet this knowledge and its application are not always accessible to practicing physical therapists or other clinicians. This article aims to summarize the main psychological processes involved in the development of chronic pain disability and to derive some guidelines for treatment and future research. To this end, the focus is on the paradox of why coping strategies that are helpful in the short term continue to be used even when-ironically-they maintain the problem in the long term. To aid in summarizing current knowledge, 4 tenets that elucidate the etiology of chronic pain are described. These tenets emphasize that chronic pain disability is a developmental process over time, contextual factors set the stage for this development, underlying transdiagnostic psychological factors fuel this development, and the principles of learning steer the development of pain behaviors. With these tenets, an explanation of how a chronic problem develops for one person but not another is provided. Finally, hypotheses that can be empirically tested to guide clinical application as well as basic research are generated. In conclusion, understanding the psychological processes underlying the etiology of chronic pain provides testable ideas and a path forward for improving treatment interventions.

Avoiding or enduring painful sex? A prospective study of coping and psychosexual function in vulvovaginal pain

BACKGROUND

Recurring vulvovaginal pain is common, with evident effects on affected women's lives. Little is known about how affected women cope with painful sexual activities and how coping relates to pain intensity and psychosexual functioning over time. This prospective study explored the impact of avoidance and endurance on sexual function over time. Additionally, patterns of coping were studied on an individual level to increase knowledge about coping and its relation to psychosexual functioning.

METHODS

One hundred and seventeen women, 18-35 years old, with recurring vulvovaginal pain answered questionnaires at two measurement points, five months apart, assessing avoidance and endurance coping, pain intensity and psychosexual functioning. A multiple regression model explored the predictive value of avoidance and endurance on sexual function over time. Cluster analyses investigated patterns of coping and stability within the clusters. These subgroups were compared on psychosexual outcomes.

RESULTS

Avoidance at baseline was the only significant predictor of sexual function five months later. Distinct and stable subgroups with different patterns of coping were identified, where avoidance and endurance coping were used both separately and combined. Women who both avoided and endured had the most unfavourable outcomes in terms of psychosexual functioning.

CONCLUSIONS

Avoidance of sexual activities was related to reduced sexual function over time, which calls for attention and clinical interventions targeting avoidance. Additionally, women who both avoid and endure sexual activities despite pain possibly need tailored interventions, as women with this coping pattern reported the lowest levels of psychosexual functioning.

SIGNIFICANCE

In this prospective study, avoidance of sexual activities predicted sexual function over time, when controlling for pain intensity. Subgroups of women using distinct patterns of coping were identified. Those who both avoided and endured had the lowest levels of psychosexual functioning.

Context sensitive regulation of pain and emotion: Development and initial validation of a scale for context insensitive avoidance

BACKGROUND AND AIMS

Context insensitivity has been put forward as a potential mechanism explaining the high co-occurrence of pain and emotional distress. In the pain literature, the concept has only been introduced at a theoretical level and an assessment tool for exploring its impact is lacking. In an interpersonal setting, a core aspect of context sensitivity and insensitivity concerns when to disclose and when to avoid expressing pain and related distress. Both context insensitive disclosure and context insensitive avoidance may hamper interpersonal support and fuel the problem. This exploratory study describes an attempt to develop a self-report instrument to assess tendencies to disclose vs. avoid expressions of pain and related distress, as well as self-perceived adjustment of disclosure vs. avoidance to the context.

METHODS

A pool of items was systematically developed to assess different aspects of context insensitivity, including disclosure vs. avoidance of expression. 105 participants with persistent pain were recruited at pain rehabilitation clinics (80% of the sample) and in a university setting (20% of the sample). The participants responded to the pool of items as well as to a number of validated self-report instruments covering pain, pain-related disability, pain catastrophizing, emotion regulation tendencies, self-compassion and pain acceptance. The analyses explored the factorial structure of the initial instrument, as well as the criterion and construct validity.

RESULTS

The analyses confirmed a stable underlying structure of the initial scale, with four distinct factors explaining 64.4% of the total variance. However, the criterion and construct validity could only be confirmed for one of the factors, which contained items reflecting context insensitive avoidance of expression. Consequently, only this factor, demonstrating very good internal consistency, was kept in the final version of the instrument which was named context insensitive avoidance (CIA).

CONCLUSIONS

We found support for the final version of our instrument, capturing one prominent aspect of context insensitivity. Avoidance of expression was related to higher ratings of pain, disability, catastrophizing and suppression as well as to lower levels of self-compassion. We encourage further studies to explore the impact of context insensitive avoidance for regulating pain and associated negative emotions. Yet, more research is needed that goes beyond self-report and includes other aspects of context. It is urgent to develop systematic ways for assessing context insensitivity, as it will enhance our understanding of regulatory strategies as potential transdiagnostic mechanisms in pain and emotion.

IMPLICATIONS

This tool for assessing contextually insensitive avoidance of expression could potentially be used both clinically and in future research to advance our understanding of comorbid problems with pain and emotional distress. Further research is needed to develop methods for assessing other aspects of context insensitivity to fully understand its impact in patients suffering from pain.

Can training in empathetic validation improve medical students' communication with patients suffering pain? A test of concept

Objective data show that medical students can learn empathetic validation techniques readily. Validation improves communication and satisfaction and may be appropriate for training medical professionals.

Introduction:

Patient-centered, empathetic communication has been recommended as a means for improving the health care of patients suffering pain. However, a problem has been training health care providers since programs may be time-consuming and difficult to learn. Validation, a form of empathetic response that communicates that what a patient experiences is accepted as true, has been suggested as an appropriate method for improving communication with patients suffering pain.

Objectives:

We study the immediate effects of providing medical students with a 2-session (45-minute duration each) program in validation skills on communication.

Methods:

A one group, pretest vs posttest design was employed with 22 volunteer medical students. To control patient variables, actors simulated 1 of 2 patient scenarios (randomly provided at pretest and posttest). Video recordings were blindly evaluated. Self-ratings of validation and satisfaction were also employed.

Results:

Observed validation responses increased significantly after training and corresponded to significant reductions in invalidating responses. Both the patient simulators and the medical students were significantly more satisfied after the training.

Conclusions:

We demonstrated that training empathetic validation results in improved communication thus extending previous findings to a medical setting with patients suffering pain. Our results suggest that it would be feasible to provide validation training for health care providers and this warrants further investigation in controlled studies.
