Trauma matters: psychological interventions for comorbid psychosocial trauma and chronic pain

The pain of PTSD: integrating persistent or chronic pain within emotional processing theory of posttraumatic stress disorder

Background: Posttraumatic stress disorder (PTSD) and chronic pain are devastating conditions that often co-occur. Current understanding of comorbid PTSD and chronic pain is limited, and treatment options are undereffective.Objective: This paper presents a theoretical basis for conceptualising chronic pain symptoms within Emotional Processing Theory (EPT), the foundation for Prolonged Exposure (PE), an effective treatment for PTSD. EPT conceptualises the development and treatment of PTSD using a trauma structure that strongly overlaps with pain's neurobiology.Method: This paper proposes a model of shared aetiology and treatment of comorbid PTSD and chronic pain, emphasising these shared neurobiological underpinnings. Discussion details how the comorbidity is maintained through parallel avoidance processes focused on: (1) trauma memories and reminders in PTSD preventing reduction of negative affect (extinction) and inhibitory learning, and (2) physical pain in chronic pain fuelling increased pain and reduced function.Results: A conceptualisation is presented on how PTSD and chronic pain symptomology can be addressed within the EPT framework, increasing the confidence of providers and patients while addressing an important gap in the literature. Finally, recommendations for providers using PE with patients with PTSD and pain are provided including a case example and treatment plan based on real patients.Conclusions: This model provides a clinically useful understanding of the underlying neurobiology for the co-occurrence of PTSD and chronic pain and offers direction for future research.

"I am not pain, I have pain": A pilot study examining iRest yoga nidra as a mind-body intervention for persistent pain

PURPOSE

This pilot study was the first of its kind to examine the experiences of people with persistent pain engaging in a six-week iRest for Pain group program as part of multidisciplinary pain care.

METHOD

The present study used a qualitative, phenomenological design and reflexive thematic analysis to gain an understanding of the firsthand experience of patients who participated in the iRest for Pain group program. This program was offered in a specialist outpatient pain management service within a regional public hospital in Victoria, Australia.

RESULTS

Participants reported they experienced iRest Yoga Nidra as personal and therapeutic, that the practice facilitated deep relaxation and restoration; for some participants trauma reprocessing and integration; improved pain self-management and self-efficacy, as well as dis-identification from persisting pain as personal identity. Additionally, some participants reported motivation and confidence to use iRest instead of medication, to reduce dependence on opioid medications.

CONCLUSION

The iRest for Pain group program presents a personally therapeutic and innovative mind-body intervention, which could be offered at various phases from primary to tertiary specialised pain care.

Associations of abuse experiences in childhood/adolescence and adulthood to pain, sexual functioning, and mental health among women with urogenital pain

OBJECTIVE

Urogenital pain affects 14-25 % of women and is predicted by prior abuse. The purpose of this study was to investigate associations of abuse type (sexual, physical, emotional, verbal) and timing (childhood, adolescence, adulthood) on outcomes (depression, anxiety, pain, sexual functioning).

METHODS

Women (N = 350; age M = 48.44) presenting with pain at a tertiary women's urology center reported whether they had experienced each type of abuse at each time point and completed outcome measures.

RESULTS

Latent class analysis of abuse types and timings identified a 4-class solution which differed primarily in phase of life for which abuse types (verbal, emotional, and physical, but not sexual) were elevated: 1) little or no abuse throughout life (66.6 %), 2) childhood/adolescent abuse only (14.6 %), 3) adulthood abuse only (8.3 %), or 4) abuse across the life course (10.6 %). Statistical comparisons between classes revealed abuse throughout life or in childhood/adolescence only was associated with depression and abuse throughout life, with anxiety (p < .001, d = 0.48-1.40), compared to no abuse. However, abuse over life or in adulthood only, but not childhood/adolescent only, was associated with pain interference, pain intensity, and low sexual satisfaction (p < .05, d = 0.38-0.77).

CONCLUSION

These patterns suggest that when abuse occurs may matter differentially in terms of mental and physical health; abuse (especially emotional/verbal and physical) in both childhood and adulthood may predispose to poor mental health, whereas adulthood abuse may be more associated with pain and functioning. One should assess when abuse occurs-including adulthood-in addition to type of abuse to understand its association with outcomes.

Physical health correlates of co-occurring chronic pain and PTSD Among U.S. Veterans: Results from a nationally representative study

Co-occurring chronic pain and posttraumatic stress disorder (PTSD) affects between 4%-8% of the U.S. veteran population. A large body of research has documented the psychosocial burden of the co-occurrence, but fewer studies have examined physical health conditions and functioning. The current study aimed to address this gap by examining physical health conditions and functioning of co-occurring chronic pain and PTSD. Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 4,069 (age=62.2 years) U.S. veterans in 2019-2020. The sample was predominantly male (N = 3,564; 90.2%) and non-Hispanic White (N = 3,318; 78.0%). PTSD diagnoses were determined using the PTSD Checklist for DSM-5 and chronic pain and other physical health conditions using self-report and validated measures. Logistic regression analyses revealed that veterans with co-occurring chronic pain and PTSD were generally more likely to have a physical health condition (ORs 2.79-9.53) or a cognitive disorder (OR=16.55) relative to controls (ORs 2.79-9.53). ANCOVA analyses revealed that relative to veterans with chronic pain or PTSD only, those with both chronic pain and PTSD had worse physical functioning across several domains (ds=0.32-1.13). Results underscore the importance of approaching co-occurring chronic pain and PTSD using a whole person approach to care that targets both physical and mental health concerns.

Prevalence of Depression and Anxiety Among Adults With Chronic Pain: A Systematic Review and Meta-Analysis

Importance

Depression and anxiety are common among adults with chronic pain, but their prevalence is unclear.

Objectives

To evaluate the prevalence of depression and anxiety among adults with chronic pain and identify factors that moderate prevalence.

Data Sources

A literature search was conducted of MEDLINE, Embase, PsycINFO, and Cochrane Library from January 2013 to October 2023.

Study Selection

Studies reporting the prevalence of depression or anxiety using a validated assessment tool among adults with chronic pain (excluding chronic headache disorders).

Data Extraction and Synthesis

A total of 31 159 initial records were identified, and 5177 full texts were screened. Data were extracted per the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline using Covidence. Two independent reviewers completed abstract screening, full-text review, and data extraction and rated risk of bias. Random-effects meta-analyses were applied to pool prevalence, assess moderation, and compare prevalence of depression or anxiety among samples with chronic pain vs control samples.

Main Outcomes and Measures

Prevalence of depression and anxiety based on clinically significant symptoms or diagnosis. The moderators of prevalence identified were pain condition, recruitment setting, continent, age, percentage female, and pain duration.

Results

The search identified 376 studies from 50 countries comprising 347 468 individuals (mean [SD] age, 51.3 [9.5] years; 70.0% female) with chronic pain. Among adults with chronic pain, clinical symptoms of depression were present in 39.3% (95% CI, 37.3%-41.1%; I2 = 98.9%), and clinical symptoms of anxiety were present in 40.2% (95% CI, 38.0%-42.4%; I2 = 99.0%). Prevalence differed by pain condition (highest among samples of people with fibromyalgia [depression, 54.0% (95% CI, 48.5%-59.4%); anxiety, 55.5% (95% CI, 50.4%-60.4%)]; lowest among samples of people with arthritis conditions [eg, osteoarthritis: depression, 29.1% (95% CI, 20.3%-39.7%); anxiety, 17.5% (95% CI, 6.6%-38.8%)]) and was highest among younger people (depression, β = -0.02 [95% CI, -0.03 to -0.01]; anxiety, β = -0.02 [95% CI, -0.03 to -0.01]) and women (depression, β = 0.69 [95% CI, 0.31-1.08]; anxiety, β = 0.90 [95% CI, 0.48-1.33]). With regard to diagnoses, 36.7% (95% CI, 29.0%-45.1%) had a major depressive disorder, and 16.7% (95% CI, 11.8%-23.2%) had generalized anxiety disorder. Women, younger people, and people with nociplastic pain (ie, pain arising from altered nociception without tissue damage) were most likely to have depression and anxiety.

Conclusions and Relevance

In this systematic review and meta-analysis of depression and anxiety among individuals with chronic pain, approximately 40% of adults had clinically significant depression and anxiety. Women, younger people, and people with nociplastic pain were most likely to have depression and anxiety. The co-occurrence of chronic pain with depression and anxiety is a significant public health concern necessitating routine screening in clinical settings, equitable access to specialty care, and innovative treatment development.

Multisite pain among United States Veterans with posttraumatic stress disorder: Prevalence, predictors, and associations with symptom clusters

Persistent pain in multiple distinct body sites is associated with poorer functional outcomes above and beyond pain intensity and interference. Veterans, and especially those with posttraumatic stress disorder (PTSD), may be at risk for multisite pain. However, the research to date characterizing this presentation is limited. This secondary analysis examined the prevalence of multisite pain in a cross-sectional sample of Veterans and explored demographic, military service-related, and PTSD symptom cluster variables associated with multisite pain among those with clinically significant PTSD symptoms. Participants were 4303 post-9/11 U.S. Veterans (16.55% female gender, 58.45% White/Caucasian, Mage = 35.52), of whom 1375 (31.95%) had clinically significant PTSD symptoms. Multisite pain was defined as endorsing pain that "bothered [me] a lot" in ≥3 body sites out of 5 on the Patient Healthcare Questionnaire-15. A total of 20.03% of all participants, and 40.00% of those with likely PTSD, reported multisite pain. Female gender (OR = 1.55), older age (OR = 1.70), minority race identification (White/Caucasian racial identity OR = 0.75), history of military sexual trauma (OR = 1.99), and spine, abdomen and joint/muscle injuries (ORs = 1.66-3.68) were associated with higher odds of multisite pain. Adjusting for these potential confounders, higher z-scores on the PTSD arousal/reactivity (OR = 1.58, p <.001) subscale was associated with higher multisite pain odds. In summary, multisite pain was common among Veterans with PTSD, especially those who experienced military sexual trauma or certain physical injuries. Multisite pain and PTSD may be associated due to a shared threat reactivity mechanism. PERSPECTIVE: This study investigates the rates and factors associated with having pain in three or more distinct body sites (multisite pain) among United States Veterans. The study findings highlight the unique importance of specific posttraumatic stress symptoms and experiences associated with multisite pain.

Trauma Erodes Financial Returns of Educational Attainment

Background

Educational attainment is often regarded as a pathway to economic stability and social mobility. However, the Minorities' Diminished Returns (MDRs) framework has demonstrated that the effects of educational attainment on various economic, behavioral, and health outcomes are weaker for marginalized populations, including racial/ethnic minorities, immigrants, LGBTQ+ individuals, and those living in disadvantaged areas. While MDRs have been documented for various marginalized demographic groups, the role of trauma in moderating socioeconomic outcomes remains underexplored.

Objective

This study examines whether lifetime trauma exposure diminishes the positive association between educational attainment and poverty-to-income ratio (PIR), a key indicator of economic well-being.

Methods

Using data from the National Survey of American Life (NSAL), we analyzed a nationally representative sample of 6,008 adults, including Black, White, Latino, and Other racial/ethnic groups. We employed linear regression models to evaluate the association between the independent variable educational attainment and the outcome PIR. We then tested lifetime trauma as a moderator of this association. Models controlled for age, gender, employment, and race/ethnicity.

Results

Educational attainment was positively associated with PIR across all groups, but the strength of this association was significantly attenuated for individuals with a history of lifetime trauma. These effects were independent of covariates.

Conclusions

These findings extend the MDRs framework by highlighting trauma as a potential contributor to diminished returns of education on socioeconomic well-being. Structural inequities that increase trauma exposure in minoritized populations may also limit the economic benefits of education, particularly for groups with multiple trauma exposures. Policies aimed at addressing economic inequality must integrate social policies that reduce trauma and stress.

The Impact of Stressful Life Events on Centralized Pain and Pain Intensity: A Combined Model Examining the Mediating Roles of Anger and Perceived Injustice Among Racially Minoritized Adults With Chronic Pain

Stressful life events are highly associated with chronic pain. Yet, research is needed to identify the psychological mechanisms that link life adversity and pain, especially studies that test comprehensive models, recruit racially diverse samples, and measure varied pain-related symptoms. This study examined the relationship between stressful life events and pain in a racially diverse sample and tested the potential mediating roles of both anger and perceived injustice. Both centralized pain symptoms and pain intensity were the outcomes. Analyses consisted of 2 cross-sectional, mediation models among 673 adults with self-reported chronic pain who were racially diverse (Black: n = 258, Latine: n = 254, Asian American: n = 161). The results indicated a positive relationship between stressful life events and centralized pain symptoms (b = 2.53, P < .001) and pain intensity (b = .20, P < .001). In parallel mediation analyses, anger (b = .91, 95% CI = .67, 1.17) and perceived injustice (b = .86, 95% CI = .64, 1.11) acted as partial mediators on centralized pain symptoms. Also, anger (b = .05, 95% CI = .03, .08) and perceived injustice (b = .11, 95% CI = .08, .14) acted as full mediators on pain intensity. The combined psychosocial variables accounted for 51% of centralized pain symptoms and 26% of pain intensity. The findings suggest that psychosocial factors are significantly associated with pain outcomes. Future research is needed to investigate exposure to adversity in life, anger, and perceived injustice together as psychosocial mechanisms of pain symptoms. PERSPECTIVE: Among racially minoritized adults with chronic pain, this article presents empirical evidence that stressful life events, anger, and perceived injustice are associated with centralized pain symptoms and pain intensity. This could guide psychological intervention to focus on anger and perceived injustice, especially when addressing centralized pain.

Childhood trauma, PTSD/CPTSD and chronic pain: A systematic review

BACKGROUND

Despite the growing body of literature on posttraumatic stress disorder (PTSD) and chronic pain comorbidity, studies taking into account the role of childhood exposure to traumatic and adverse events remains minimal. Additionally, it has been well established that survivors of childhood trauma may develop more complex reactions that extend beyond those observed in PTSD, typically categorized as complex trauma or CPTSD. Given the recent introduction of CPTSD within diagnostic nomenclature, the aim of the present study is to describe associations between childhood trauma in relation to PTSD/CPTSD and pain outcomes in adults with chronic pain.

METHODS

Following PRSIMA guidelines, a systematic review was performed using the databases Pubmed, PsychInfo, Psychology and Behavioral Sciences Collection, and Web of Science. Articles in English or French that reported on childhood trauma, PTSD/CPTSD and pain outcomes in individuals with chronic pain were included. Titles and abstracts were screened by two authors independently and full texts were consequently evaluated and assessed on methodological quality using JBI checklist tools. Study design and sample characteristics, childhood trauma, PTSD/CPTSD, pain outcomes as well as author's recommendations for scientific research and clinical practice were extracted for analyses.

RESULTS

Of the initial 295 search records, 13 studies were included in this review. Only four studies explicitly assessed links between trauma factors and pain symptoms in individuals with chronic pain. Findings highlight the long-term and complex impact of cumulative childhood maltreatment (e.g., abuse and neglect) on both PTSD/CPTSD and chronic pain outcomes in adulthood.

CONCLUSION

This review contributes to current conceptual models of PTSD and chronic pain comorbidity, while adding to the role of childhood trauma and CPTSD. The need for clinical and translational pain research is emphasized to further support specialized PTSD/CPTSD treatment as well as trauma-informed pain management in routine care.

Integrating mechanistic-based and classification-based concepts into perioperative pain management: an educational guide for acute pain physicians

Chronic pain begins with acute pain. Physicians tend to classify pain by duration (acute vs chronic) and mechanism (nociceptive, neuropathic and nociplastic). Although this taxonomy may facilitate diagnosis and documentation, such categories are to some degree arbitrary constructs, with significant overlap in terms of mechanisms and treatments. In clinical practice, there are myriad different definitions for chronic pain and a substantial portion of chronic pain involves mixed phenotypes. Classification of pain based on acuity and mechanisms informs management at all levels and constitutes a critical part of guidelines and treatment for chronic pain care. Yet specialty care is often siloed, with advances in understanding lagging years behind in some areas in which these developments should be at the forefront of clinical practice. For example, in perioperative pain management, enhanced recovery protocols are not standardized and tend to drive treatment without consideration of mechanisms, which in many cases may be incongruent with personalized medicine and mechanism-based treatment. In this educational document, we discuss mechanisms and classification of pain as it pertains to commonly performed surgical procedures. Our goal is to provide a clinical reference for the acute pain physician to facilitate pain management decision-making (both diagnosis and therapy) in the perioperative period.

Stepped collaborative care for pain and posttraumatic stress disorder after major trauma: a randomized controlled feasibility trial

PURPOSE

To examine feasibility and acceptability of providing stepped collaborative care case management targeting posttraumatic stress disorder (PTSD) and pain symptoms after major traumatic injury.

MATERIALS AND METHODS

Participants were major trauma survivors in Victoria, Australia, at risk of persistent pain or PTSD with high baseline symptoms. Participants were block-randomized, stratified by compensation-status, to the usual care (n = 15) or intervention (n = 17) group (46% of eligible patients). The intervention was adapted from existing stepped collaborative care interventions with input from interdisciplinary experts and people with lived experience in trauma and disability. The proactive case management intervention targeted PTSD and pain management for 6-months using motivational interviewing, cognitive behavioral therapy strategies, and collaborative care. Qualitative interviews explored intervention acceptability.

RESULTS

Intervention participants received a median of 7 h case manager contact and reported that they valued the supportive and non-judgmental listening, and timely access to effective strategies, resources, and treatments post-injury from the case manager. Participants reported few disadvantages from participation, and positive impacts on symptoms and recovery outcomes consistent with the reduction in PTSD and pain symptoms measured at 1-, 3- and 6-months.

CONCLUSIONS

Stepped collaborative care was low-cost, feasible, and acceptable to people at risk of PTSD or pain after major trauma.IMPLICATIONS FOR REHABILITATIONAfter hospitalization for injury, people can experience difficulty accessing timely support to manage posttraumatic stress, pain and other concerns.Stepped case management-based interventions that provide individualized support and collaborative care have reduced posttraumatic stress symptom severity for patients admitted to American trauma centers.We showed that this model of care could be adapted to target pain and mental health in the trauma system in Victoria, Australia.The intervention was low cost, acceptable and highly valued by most participants who perceived that it helped them use strategies to better manage post-traumatic symptoms, and to access clinicians and treatments relevant to their needs.

Pain neuroscience education improves post-traumatic stress disorder, disability, and pain self-efficacy in veterans and service members with chronic low back pain: Preliminary results from a randomized controlled trial with 12-month follow-up

Post-traumatic stress disorder (PTSD) and chronic low back pain (CLBP) are frequently co-morbid. Some research suggests that PTSD and CLBP may share common neurobiological mechanisms related to stress. Traditional biomedical education may be ineffective for PTSD and CLBP, especially when co-morbid. The purpose of this study is to determine if pain neuroscience education (PNE) is more effective than traditional education in reducing PTSD, disability, pain, and maladaptive beliefs in patients with CLBP. Participants with CLBP and possible PTSD/PTSD-symptoms were recruited for this study. Participants were randomly allocated to a PNE group or a traditional education group. The intervention included 30 minutes of education followed by a standardized exercise program once a week for 4-weeks with a 4 and 8-week follow-up and healthcare utilization assessed at 12-months. Forty-eight participants consented for this research study with 39 allocated to treatment (PNE n = 18, traditional n = 21). PNE participants were more likely to achieve a clinically meaningful reduction in PTSD symptoms and disability at short-term follow-up. At 12-months, the PNE group utilized healthcare with 76% lower costs. In participants with CLBP, PNE may reduce hypervigilance toward pain and improve PTSD symptoms. Participants who received PNE were more confident body-tissues were safe to exercise. These beliefs about pain could contribute to a decrease in perceived disability and healthcare consumption for CLBP.

Emotional Awareness and Expression Therapy vs Cognitive Behavioral Therapy for Chronic Pain in Older Veterans: A Randomized Clinical Trial

Importance

Chronic pain is common and disabling in older adults, and psychological interventions are indicated. However, the gold standard approach, cognitive-behavioral therapy (CBT), produces only modest benefits, and more powerful options are needed.

Objectives

To evaluate whether emotional awareness and expression therapy (EAET) is superior to CBT for treatment of chronic pain among predominantly male older veterans and whether higher baseline depression, anxiety, or posttraumatic stress disorder (PTSD) symptoms-key targets of EAET-moderate treatment response.

Design, Setting, and Participants

This 2-arm randomized clinical trial was conducted from May 16, 2019, to September 14, 2023, in the US Department of Veterans Affairs Greater Los Angeles Healthcare System. The trial included a racially and ethnically diverse group of veterans aged 60 to 95 years with at least 3 months of musculoskeletal pain.

Interventions

Emotional awareness and expression therapy or CBT, conducted concurrently, each presented as one 90-minute individual session followed by eight 90-minute group sessions.

Main Outcomes and Measures

The primary outcome was Brief Pain Inventory pain severity (range, 0 to 10) from baseline to posttreatment (week 10, primary end point) and 6-month follow-up. Secondary outcomes included Patient Reported Outcomes Institute Measurement System Anxiety, Depression, Fatigue, General Life Satisfaction (NIH Toolbox), Pain Interference, and Sleep Disturbance Short Forms, Patient Global Impression of Change (PGIC), and Satisfaction with Therapy and Therapist Scale-Revised. A subset of participants completed the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition). All analyses were for the intention-to-treat population and included all randomized participants.

Results

Among 126 randomized participants (66 in the EAET group and 60 in the CBT group; mean [SD] age, 71.9 [5.9] years; 116 [92%] male), 111 (88%) completed posttreatment, and 104 (82%) completed the 6-month follow-up. The EAET was superior to CBT for the primary outcome of reduction in pain severity at posttreatment (estimate, -1.59 [95% CI, -2.35 to -0.83]; P < .001) and follow-up (estimate, -1.01 [95% CI, -1.78 to -0.24]; P = .01). A greater percentage of participants in EAET vs CBT had clinically significant (at least 30%) pain reduction (63% vs 17%; odds ratio, 21.54 [95% CI, 4.66-99.56]; P < .001) at posttreatment. In addition, EAET was superior to CBT on 50% pain reduction (35% vs 7%; odds ratio, 11.77 [95% CI, 2.38-58.25]; P = .002), anxiety (estimate, -2.49 [95% CI, -4.30 to -0.68]; P = .006), depression (estimate, -3.06 [95% CI, -5.88 to -0.25]; P = .03), general life satisfaction (estimate, 1.23 [95% CI, 0.36-2.10]; P = .005), PTSD symptoms (estimate, -4.39 [95% CI, -8.44 to -0.34]; P = .03), PGIC score (estimate, 1.46 [95% CI, 0.77-2.15]; P < .001), and global treatment satisfaction (estimate, 0.28 [95% CI, 0.12-0.45]; P < .001) at posttreatment. Higher baseline depression (estimate, -1.55 [95% CI, -0.37 to 2.73]; P < .001), anxiety (estimate, -1.53 [95% CI, -2.19 to -0.88]; P < .001), and PTSD symptoms (estimate, -1.69 [95% CI, -2.96 to -0.42]; P = .009) moderated greater reduction in pain severity after EAET but not CBT.

Conclusions and Relevance

The results of this randomized clinical trial suggest that EAET may be a preferred intervention for medically and psychiatrically complex patients with pain. The societal burden of chronic pain could be improved by further incorporating the principles of EAET into mainstream clinical pain medicine.

What Happens Next? Maintenance of Gains After Discharge From VA Residential PTSD Treatment

ABSTRACT

Residential posttraumatic stress disorder (PTSD) treatment in the Department of Veterans Affairs is helpful for many Veterans, yet the majority experience symptom rebound after discharge. This study examined a national cohort of Veterans (n = 1872) who completed VA residential PTSD treatment and identified factors associated with maintenance of gains from discharge to 4-month follow-up. We generated three logistic regression models based on response profiles during residential treatment. In the "marginal responders" group, 1-3 "booster" sessions of PTSD treatment were associated with decreased odds of maintenance of gains (odds ratio [OR], 0.42), whereas in the "clinically significant responders" group, these sessions were associated with increased odds of maintenance of gains (OR, 2.89). Greater pain severity was associated with decreased odds of maintenance of gains in the "clinically significant responder" group (OR, 0.90). Results demonstrate several avenues for intervention including targeting pain severity and matching aftercare psychotherapy to Veteran residential treatment response.

Broadening the Scope of Resilience in Chronic Pain: Methods, Social Context, and Development

PURPOSE OF REVIEW

A wellspring of new research has offered varying models of resilience in chronic pain populations; however, resilience is a multifaceted and occasionally nebulous construct. The current review explores definitional and methodological issues in existing observational and clinical studies and offers new directions for future studies of pain resilience.

RECENT FINDINGS

Definitions of pain resilience have historically relied heavily upon self-report and from relatively narrow scientific domains (e.g., positive psychology) and in narrow demographic groups (i.e., Caucasian, affluent, or highly educated adults). Meta-analytic and systematic reviews have noted moderate overall quality of resilience-focused assessment and treatment in chronic pain, which may be attributable to these narrow definitions. Integration of research from affiliated fields (developmental models, neuroimaging, research on historically underrepresented groups, trauma psychology) has the potential to enrich current models of pain resilience and ultimately improve the empirical and clinical utility of resilience models in chronic pain.

Group eye movement desensitization and reprocessing (EMDR) in chronic pain patients

The prevalence of chronic pain is increasing, and conventional pain therapies often have limited efficacy in individuals with high levels of psychological distress and a history of trauma. In this context, the use of Eye Movement Desensitization and Reprocessing (EMDR), an evidence-based psychotherapy approach for the treatment of posttraumatic stress disorder, is becoming increasingly important. EMDR shows promising results, particularly for patients with pain and high levels of emotional distress. Although group therapy is becoming increasingly popular in pain management, EMDR has mainly been studied as an individual treatment. However, a systematic review suggests that group therapy can be an effective tool for improving mental health outcomes, especially when trauma is addressed together. Based on these findings, an outpatient EMDR group program was developed for patients with chronic pain. The program consists of a total of four treatment days with 5-5.5 h therapy sessions each day and provides patients with a supportive environment in which they can learn effective pain management strategies and interact with other patients with similar experiences. Initial pilot evaluations indicate high efficacy and adequate safety for patients with chronic pain.

Associations of Chronic Pain With Psychosocial Outcomes After Traumatic Brain Injury: A NIDILRR and VA TBI Model Systems Collaborative Project

OBJECTIVE

To examine the differences in participation, life satisfaction, and psychosocial outcomes among individuals with traumatic brain injury (TBI) endorsing current, past, or no chronic pain.

SETTING

Community.

PARTICIPANTS

Three thousand eight hundred four TBI Model Systems participants 1 to 30 years of age postinjury classified into 1 of 3 groups based on their pain experience: current pain, past pain, no pain completed a Pain Survey at their usual follow-up appointment which on average was approximately 8 years postinjury.

DESIGN

Multisite, cross-sectional observational cohort study.

MAIN OUTCOME MEASURES

Sociodemographic and injury characteristics and psychosocial outcomes (ie, satisfaction with life, depression, anxiety, posttraumatic stress disorder [PTSD], sleep quality, community participation).

RESULTS

Persons with current chronic pain demonstrated higher scores on measures of PTSD, anxiety, and depression, and the lower scores on measures of sleep quality, community participation and satisfaction with life. Those with resolved past pain had mean scores for these outcomes that were all between the current and no chronic pain groups, but always closest to the no pain group. After adjusting for sociodemographic and function in multivariate analysis, having current chronic pain was associated with more negative psychosocial outcomes. The largest effect sizes (ES; in absolute value) were observed for the PTSD, depression, anxiety, and sleep quality measures (ES = 0.52-0.81) when comparing current pain to past or no pain, smaller ES were observed for life satisfaction (ES = 0.22-0.37) and out and about participation (ES = 0.16-0.18). When comparing past and no pain groups, adjusted ES were generally small for life satisfaction, PTSD, depression, anxiety, and sleep quality (ES = 0.10-0.23) and minimal for participation outcomes (ES = 0.02-0.06).

CONCLUSIONS

Chronic pain is prevalent among individuals with TBI and is associated with poorer psychosocial outcomes, especially for PTSD, depression, anxiety, and sleep disturbance. The results from this study highlight the presence of modifiable comorbidities among those with chronic pain and TBI. Persons who experience persistent pain following TBI may be at greater risk for worse psychosocial outcomes.

Emotion-Focused Psychodynamic Interview for People with Chronic Musculoskeletal Pain and Childhood Adversity: A Randomized Controlled Trial

Childhood adversity and emotional conflicts are associated with the presence and severity of chronic musculoskeletal pain (CMP), yet common treatments for CMP do not address such risk factors. We developed a single session, emotion-focused psychodynamic interview, based on Emotional Awareness and Expression Therapy and Intensive Short-term Psychodynamic Therapy, and we tested the interview's effects on pain-related outcomes and potential psychological mediators in a randomized, controlled trial. Adults (N = 91; ages 21-70, M = 44.64; 87.9% women) reporting CMP and at least 3 adverse childhood experiences completed measures at baseline and 6-week follow-up. Participants were randomized to immediate interview or waitlist control conditions. The 90-minute interview was conducted via videoconference, and the interviewer elicited disclosure of adversities and conflicts, linked these with pain, and encouraged the experience and expression of adaptive emotions. Analyses indicated that conditions did not differ significantly on change in pain severity; however, compared to control, the interview led to a significantly greater reduction in pain interference (P = .016, ηp2 = .05) and a similar trend for anxiety (P = .058, ηp2 = .04). The interview also significantly changed several potential mediators: pain-related anxiety (P = .008, ηp2 = .06), pain controllability (P = .016, ηp2 = .06), and psychological (P < .001, ηp2 = .15) and brain attributions (P = .022, ηp2 = .05) for pain. Participants viewed the interview as very valuable. We conclude that addressing childhood adversities and conflicts in a psychodynamic interview is beneficial for people with CMP. PERSPECTIVE: This study found that, compared to waitlist control, a 90-minute, remotely-administered, emotion-focused, psychodynamic interview improved pain interference, and anxiety among adults with chronic musculoskeletal pain and childhood adversity. Intensive emotional work can be done in a single session to the benefit of patients with chronic musculoskeletal pain.

Occupational Therapists' Beliefs and Experiences Managing Chronic Pain, Wellness, and Occupational Performance

Chronic disease prevention, health, and wellness have become primary practice areas for occupational therapy. Occupational therapists (OTs) in pain rehabilitation are established as essential members of comprehensive and multidisciplinary pain management teams, focusing on increasing occupational performance through participation. This study's purpose was to investigate OTs' experiences managing chronic pain and to explore OTs' effectiveness in supporting clients' wellness and occupational performance through interventions. Eleven OTs (n = 11) participated with three themes emerging on chronic pain, interventions, and holistic teams. Findings suggest that OTs are successful at treating chronic pain, supporting wellness and occupational performance when their interventions are health-promoting, and clients are enabled to take an active role in their chronic pain management. This study demonstrates the critical impact OTs can have in multidisciplinary teams on clients' outcomes, such as increased occupational performance, wellness, and quality of life (QOL) through engagement in meaningful occupations.

Hidden family rules: perspective on a dysfunctional paternalistic system and the persistence of pain

This article explores how paternalistic control and power reside within the family system and how this may influence pain and its persistence. Drawing upon clinical case studies and existing literature, this exploration emphasises the role of paternal dysfunction in creating emotional memory images and delves into how this may influence the chronification and treatment resistance of pain (i.e., making pain "sticky"). We argue that a dysfunctional paternalistic family system, often characterised by authoritarian dynamics, emotional neglect, and abuse, results in adverse experiences and emotional memory images that create a fertile ground for the entrenchment and propagation of psychosomatic symptoms, including pain. Further, the paper emphasizes the potential intergenerational effects of such a scenario, where inherited "Family Rules" drive maladaptive coping mechanisms, which contribute to the persistence of psychological and physiological distress across generations. Understanding these complexities offers new perspectives on treating psychological disorders and their physiological ramifications. It also highlights the urgency of addressing dysfunctional familial dynamics in psychotherapeutic interventions for both immediate and long-term psychophysiological health outcomes.

Understanding the gaps in headache and migraine treatment with psychological and behavioral interventions: A narrative review

OBJECTIVE

In this narrative review, we summarize relevant literature pertaining to psychosocial risk factors for headache and migraine progression, current behavioral and psychological treatments, and consider promising treatments.

BACKGROUND

Headache and migraine are common and associated with significant burden and disability. Current treatments targeting psychosocial risk factors show modest outcomes and do not directly address the impact of early life adversity, including the development of maladaptive emotional processing. An intervention that could address these factors and include components of current evidence-based interventions may lead to improved outcomes.

METHODS

We searched PubMed and Google Scholar for articles through December 2022. Search terms included headache, migraine, psychological interventions, behavioral interventions, cognitive-behavioral therapy, mindfulness, psychiatric comorbidities, adverse childhood experiences, trauma, and emotional processing.

RESULTS

Trauma and childhood adversity show a correlation with headache and migraine progression. Developmental adversity and trauma interfere with adaptive emotional processing, which may worsen headache and migraine symptoms, while adaptive ways of experiencing emotions are shown to improve symptoms. Current behavioral and psychological interventions, such as cognitive-behavioral and mindfulness therapies, are effective treatments for headache, but they produce small to medium effect sizes and do not directly address the impact of trauma and emotional conflicts-common factors that contribute to chronicity and disability, especially among certain subpopulations of headache patients such as those with migraine. Thus, there exists a gap in current treatment.

CONCLUSION

There is a gap in headache and migraine treatment for those patients who have a history of trauma, childhood adversity, and maladaptive emotional processing. We suggest that an integrated psychological treatment that includes components of current evidence-based interventions and addresses gaps by focusing on processing trauma-related emotions may improve chronic and debilitating symptoms.

Perspectives on emotional memory images and the persistence of pain

Multiple influences prevent recovery from pain. Our viewpoint is that non-conscious emotional memory images (EMIs) triggers outdated stress responses contributing to the intractability of pain. In this perspectives article we explore the concept that EMIs contribute to the persistence of pain. We contend that psychophysiological "stress" responses, resulting from first-time, novel and unprecedented pernicious or adverse events form EMIs within very short time frames (split-second learning). Subsequently, these EMIs are re-triggered in daily living, "re-playing" stress responses. We postulate that EMIs continually "raise the alarm" to socio-ecological stimuli by re-triggering the HPA-axis and amplifying neural input associated with threat, fear, anxiety, and pain, creating a debilitating state of psychophysiological dis-ease. We position the EMI within a philosophical debate on the nature and locus of memory and explain how the EMI, irrespective of whether it is a "thing" or a metaphor, can create a basis of understanding for the client to grasp. We describe a therapeutic approach (Split-Second Unlearning) to "clear" EMIs and the "stickiness" of pain and help people embark on a healing journey. This involves surveillance of clients for micro-expression(s) signifying an in-the-moment stress response, representative of the presence of an EMI, and encouraging the client to become a curious observer within/of their own experience. This helps the client detach their EMI from its stress response. We contend that this occurs rapidly without the need to get bogged down in a whole-life narrative. We advocate further exploration of our EMI model of dis-ease in the context of intractable pain.

Perceived Injustice as a Determinant of the Severity of Post-traumatic Stress Symptoms Following Occupational Injury

BACKGROUND

The present study assessed the role of perceived injustice in the experience and persistence of post-traumatic stress symptoms (PTSS) following work-related musculoskeletal injury.

METHODS

The study sample consisted of 187 individuals who were absent from work as a result of a musculoskeletal injury. Participants completed measures of pain severity, perceived injustice, catastrophic thinking, post-traumatic stress symptoms, and disability on three occasions at three-week intervals.

RESULTS

Consistent with previous research, correlational analyses revealed significant cross-sectional relations between pain and PTSS, and between perceived injustice and PTSS. Regression analysis on baseline data revealed that perceived injustice contributed significant variance to the prediction of PTSS, beyond the variance accounted for by pain severity and catastrophic thinking. Sequential analyses provided support for a bi-directional relation between perceived injustice and PTSS. Cross-lagged regression analyses showed that early changes in perceived injustice predicted later changes in PTSS and early changes in PTSS predicted later changes in perceived injustice.

CONCLUSIONS

Possible linkages between perceived injustice and PTSS are discussed. The development of effective intervention techniques for targeting perceptions of injustice might be important for promoting recovery of PTSS consequent to musculoskeletal injury.

Mental Health Diagnoses are Not Associated With Indicators of Lower Quality Pain Care in Electronic Health Records of a National Sample of Veterans Treated in Veterans Health Administration Primary Care Settings

Prior research has demonstrated disparities in general medical care for patients with mental health conditions, but little is known about disparities in pain care. The objective of this retrospective cohort study was to determine whether mental health conditions are associated with indicators of pain care quality (PCQ) as documented by primary care clinicians in the Veterans Health Administration (VHA). We used natural language processing to analyze electronic health record data from a national sample of Veterans with moderate to severe musculoskeletal pain during primary care visits in the Fiscal Year 2017. Twelve PCQ indicators were annotated from clinician progress notes as present or absent; PCQ score was defined as the sum of these indicators. Generalized estimating equation Poisson models examined associations among mental health diagnosis categories and PCQ scores. The overall mean PCQ score across 135,408 person-visits was 8.4 (SD = 2.3). In the final adjusted model, post-traumatic stress disorder was associated with higher PCQ scores (RR = 1.006, 95%CI 1.002-1.010, P = .007). Depression, alcohol use disorder, other substance use disorder, schizophrenia, and bipolar disorder diagnoses were not associated with PCQ scores. Overall, results suggest that in this patient population, presence of a mental health condition is not associated with lower quality pain care. PERSPECTIVE: This study used a natural language processing approach to analyze medical records to determine whether mental health conditions are associated with indicators of pain care quality as documented by primary care clinicians. Findings suggest that presence of a diagnosed mental health condition is not associated with lower quality pain care.

Psychological predictors of health anxiety and pain in ambulatory presentations in a hospital emergency department

BACKGROUND

Health anxiety in attendees of out-patient medical clinics is well established; however, there has been a lack of research into health anxiety within emergency settings.

AIMS

This study explored the prevalence of health anxiety in ambulatory presentations in a tertiary emergency department (ED) as well as the factors associated with pain and health anxiety in this setting.

METHOD

A cross-sectional questionnaire design was used to gather data from adult ED ambulatory attendees across a 4-day sampling period to assess psychological and physical health variables. Number of attendances to ED over the previous 12 months was accessed through healthcare records.

RESULTS

Of the final sample (n = 106), 77% were white British, 54% were male, and 14% presented with severe health anxiety as measured by the Short Health Anxiety Inventory (≥18). Participants with pre-existing health conditions had significantly higher levels of health anxiety (M = 12.36, SE = 1.59) compared with those without (M = 7.79, SE = 0.66). Stepwise multiple regression analyses identified anxiety sensitivity and pain catastrophizing as significant independent predictors of health anxiety, explaining 51% of the variance in health anxiety. Pain catastrophizing was also a significant independent predictor of pain level, accounting for 20% of the variance.

CONCLUSION

This study provides insight into the prevalence of health anxiety in ED ambulatory presentations and key psychological predictors of health anxiety and pain. This has implications for treatment in an ED setting whereby patients may benefit from referral to medical psychology or mental health services.

Traumatic Life Experience and Pain Sensitization: Meta-analysis of Laboratory Findings

OBJECTIVES

Psychological trauma often co-occurs with pain. This relationship has been explored using laboratory pain measures; however, findings have been mixed. Previous studies have limited operationalization of trauma (eg, posttraumatic stress disorder) or pain (eg, pain thresholds), which may contribute to conflicting results. Further, prior reviews likely underrepresent trauma experiences among people who are not receiving clinical care, limiting generalizability.

MATERIALS AND METHODS

We systematically reviewed the existing literature on the relationship between psychological trauma (eg, car accidents, sexual assault, childhood abuse, neglect) and laboratory pain (ie, quantitative sensory testing measures of pain threshold, intensity, summation, modulation), using inclusive criteria. The direction of the relationship between psychological trauma and pain sensitivity was evaluated, and moderation by purported pain mechanism (ie, pain detection, suprathreshold pain, central sensitization, inhibition) was explored.

RESULTS

Analyses were conducted using 48 studies that provided 147 effect sizes. A multivariate random-effects model with robust variance estimation resulted in a small but statistically significant overall effect size of g=0.24 (P=0.0002), reflecting a positive association between psychological trauma and enhanced laboratory pain sensitivity. Upon examination of mechanistic moderators, this relationship appears driven by effects on pain detection (g=0.28, P=0.002) and central sensitization (g=0.22, P=0.04). While effect sizes were similar across all moderators, effects on suprathreshold pain and inhibition were not statistically significant.

DISCUSSION

Findings demonstrate an overall pattern of trauma-related pain enhancement and point to central sensitization as a key underlying mechanism.

"Pain, Stress, and Emotions": Uncontrolled trial of a single-session, telehealth, emotional awareness and expression therapy class for patients with chronic pain

Objectives

Trauma- and emotion-focused chronic pain interventions, particularly Emotional Awareness and Expression Therapy (EAET), show much promise for reducing pain and improving functioning. We developed a novel, single-session, telehealth-delivered EAET class ("Pain, Stress, and Emotions"; PSE) and tested it on adults with chronic pain of mixed etiology.

Methods

After an initial developmental phase, we conducted an uncontrolled trial, providing PSE to 74 individuals with chronic pain (63.5% female; 64.9% White; 60.8% with pain duration >5 years) in four class administrations. Participants completed self-report measures (primary outcomes: pain intensity and pain interference) at baseline and multiple follow-ups to 12 weeks. Linear mixed-models examined changes over time, and effect sizes were calculated on change from baseline to 4-week (primary endpoint) and 12-week follow-ups. The trial was registered with clinicaltrials.gov (NCT05014126).

Results

Participants reported high satisfaction with the PSE class. Pain intensity showed a significant, medium reduction across time (p < .001; d = 0.60 at 4 weeks); one-quarter of participants had clinically meaningful pain reduction (≥30%). Pain interference had a large reduction (p < .001; d = 0.74). There were significant but smaller improvements in most secondary outcomes (ds = 0.15 to 0.55; ps < .01). Effects were generally maintained or increased at 12-week follow-up. Higher education and baseline ambivalence over emotional expression predicted greater pain reductions.

Conclusions

People taking this EAET class had reduced pain severity and interference and improvements in other pain-related outcomes. The single-session, telehealth class holds promise as an easily delivered, efficient, and potentially impactful intervention for some patients with chronic pain, although controlled trials are needed.
