Assessing the mediating role of disenfranchising talk on the well-being of female patients with chronic overlapping pain conditions

OBJECTIVE

Disenfranchising talk (DT) occurs when health care providers discredit, silence, and stereotype patients. Although ample research has suggested associations among negative patient-provider interactions and poorer well-being, this study is the first to investigate the mediating role of patient-provider DT in exacerbating poorer pain-related health correlates.

METHODS

Female patients living with chronic overlapping pain conditions (N = 348) completed a cross-sectional survey including measures of DT, pain severity, pain catastrophizing, and pain disability, as well as demographic information. Structural equation modeling in AMOS 29 assessed whether DT mediated the relationship between age, educational attainment, and sexual orientation (demographics), and pain severity, catastrophizing, and disability (pain-related health correlates).

RESULTS

Structural equation modeling revealed that DT mediated the relationship between age, educational attainment, and sexual orientation on pain-related health correlates, such that younger and LGBQA+ patients and those with less educational attainment reported heightened pain severity, catastrophizing, and disability when they also reported DT.

CONCLUSION

In contrast to scholarship assessing how demographics and pain-related variables influence patient-provider communication, this study instead investigated the mediating role of DT in pain-related health correlates.

PRACTICE IMPLICATIONS

Providers should avoid discrediting, silencing, or stereotyping female chronic pain patients' pain to potentially avoid exacerbating pain-related health correlates.

The Spider: a visual, multisystemic symptom impact questionnaire for people with hypermobility-related disorders-validation in adults

INTRODUCTION

Hypermobility spectrum disorders (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS) are often accompanied by varied and complex multisystemic comorbid symptoms/conditions. The Spider questionnaire was developed to evaluate the presence and impact of eight common multisystemic comorbidities. Thirty-one questions across eight symptom domains assess neuromusculoskeletal, pain, fatigue, cardiac dysautonomia, urogenital, gastrointestinal, anxiety, and depression symptoms. This study aimed to evaluate the Spider's construct validity in adults.

METHOD

A cross-sectional observational study was conducted over four stages. Three international patient charities aided recruitment of participants through social media and website advertisements. Adults aged 18 to 65 years, with and without HSD/hEDS, were invited to participate. Validated, frequently used comparator questionnaires were used to establish convergent validity of Spider symptom domains. A control group was recruited for known-group validity analysis. Participants answered each Spider domain and the corresponding comparator questionnaire via surveys hosted by REDCap. Anonymous data were analysed using SPSS. Convergent validity was assessed through Spearman's correlational analysis and known-group validity through Mann-Whitney U analysis.

RESULTS

A total of 11,151 participants were recruited across the four stages. Statistically significant, moderate-to-strong correlations were found between all Spider domains and their comparators (p < 0.001, r = 0.63 to 0.80). Known-group validity analysis showed statistically significant differences (p < 0.001) between the hypermobile and control groups in all eight domains.

CONCLUSIONS

Convergent and known-group validity of the Spider was established with adults. These results suggest the Spider can measure the presence and impact of multisystemic comorbid symptoms/conditions in adults with HSD/hEDS, providing a tool which guides multidisciplinary management. Key Points • The Spider questionnaire is a novel tool assessing the presence and impact of the multisystemic comorbid symptoms/conditions associated with HSD/hEDS. • Convergent and known-group validity of the Spider questionnaire was established in adults aged 18 to 65. • This tool provides a quick and easy method to visualise the symptom profile of those with HSD/hEDS to guide symptom management.

Associations Between Adult Attachment, Pain Catastrophizing, Psychological Inflexibility and Disability in Adults with Chronic Pain

We investigated whether attachment insecurity (anxiety and avoidance) moderated the association between satisfaction with social support and pain disability. We also tested whether the relationship between insecure attachment and pain disability was serially mediated by pain catastrophising and psychological inflexibility. A large-scale cross-sectional correlational design was employed. Data were collected using an online survey. Correlation, serial mediation and moderated regression analyses were used. Data from 894 people with self-reported chronic pain were analysed. Based on correlations, age, depression, and pain intensity were included as covariates. No direct effect of satisfaction with social support on pain disability was observed in the moderation. Attachment anxiety was positively associated with pain disability (b = 1.20, t = 2.03, p < .05), but attachment avoidance was not (b = -0.08, t = -0.13, p = .90). The association between attachment anxiety and pain disability was partially mediated by pain catastrophising and psychological inflexibility (c = 1.21, t = 4.37, p < .001; a1db2 = 0.33, t = 5.15, p < .001). The relationship between attachment avoidance and pain disability was fully mediated by pain catastrophising and psychological inflexibility (c = 0.15, t = 0.54, p = .59; a1db2 = 0.13, t = 2.24, p < .05). This study provided initial evidence that pain catastrophising and psychological inflexibility mediate the association between insecure attachment and pain disability. Follow-up research using a longitudinal design is recommended.

Case Report: Methylphenidate and venlafaxine improved abdominal nociplastic pain in an adult patient with attention deficit hyperactivity disorder, autism spectrum disorder, and comorbid major depression

Introduction

Nociplastic pain (NP), classified as a third type of pain alongside nociceptive and neuropathic pain, is chronic pain arising from the amplification of nociceptive stimuli through central sensitization, despite the absence of tissue damage, sensory nerve damage, or disease. An important clinical feature of NP is that it is not only associated with pain but also with sensory hypersensitivity to sound and light and cognitive dysfunction, including mood and attention disorders. Recent studies have suggested that depression and developmental disorders, such as attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), coexist with NP at high frequency. Additionally, cognitive impairment in individuals with NP may be associated with these psychiatric comorbidities. However, to our knowledge, there are no reports on (1) multidimensional evaluation and diagnostic details of abdominal NP in adults with ADHD/ASD; (2) how ADHD drugs and antidepressants are administered when ADHD and depression coexist with NP; and (3) how central sensitization, brain function, and family relationship problems underlying NP are altered by treatments of ADHD and depression.

Case presentation

Herein, we present the case of a 51-year-old woman with abdominal NP. She developed severe right lower abdominal pain and underwent a thorough medical examination; however, the physical, medical cause remained unknown, making treatment challenging. Additionally, she took time off work as she began to complain of insomnia and anxiety. She was referred to our pain center, where a diagnosis of depression, ADHD, and ASD was confirmed, and treatment with ADHD medication was initiated. While ADHD medications alone did not yield sufficient improvement, a combination of methylphenidate and the antidepressant venlafaxine eventually led to improvements in abdominal NP, depression, ADHD symptoms, central sensitization, and family relationship issues. During treatment, cerebral blood flow in the anterior cingulate, prefrontal, and parietal cortices also improved.

Conclusion

The treatment of comorbid depression is important while treating NP, and venlafaxine may be effective, especially in cases of comorbid ADHD/ASD. Screening for developmental disorders and depression is required in patients with abdominal NP.

A prospective investigation of the prognosis of noncardiac chest pain in emergency department patients

OBJECTIVES

This study sought to describe the 2-year evolution of the intensity and frequency of noncardiac chest pain (NCCP), NCCP-related disability and health-related quality of life in a cohort of emergency department (ED) patients. It also aimed to identify and characterize subgroups of patients who share similar NCCP trajectories.

METHODS

672 consecutive patients with NCCP were prospectively recruited in two EDs. NCCP, physical and mental health-related quality of life and pain-related impairment were assessed at baseline and 6 months, 1 year and 2 years after the index ED visit.

RESULTS

Significant reductions in the intensity and frequency of NCCP and in NCCP-related disability were observed over time, with 58.1% of patients being considered NCCP-free at the 2-year follow-up. Four trajectories of NCCP intensity were identified through latent class growth mixture modelling: Worsening Trajectory (6.8%), Persistence Trajectory (20.5%), Limited Improvement Trajectory (13.1%) and Remission Trajectory (59.5%). Physical quality of life was significantly higher in the latter two trajectories at all assessment points. Patients in the Remission Trajectory reported a better mental quality of life and a greater decrease in NCCP-related disability over time than those in the other trajectories.

CONCLUSIONS

Over 40% of ED patients with NCCP experienced persistent biopsychosocial morbidity that warrants further clinical attention.

The relationship between pain, quality of life and physical activity in older community living Australians

The objective of this analysis was to investigate the relationship between pain and quality of life and physical activity as a mediator in the relationship between pain and quality of life. This study utilised a combination of questionnaire data from 503 community-living people aged 70-years and over concerning quality of life, pain, and physical activity. Participants with higher levels of pain intensity experienced lower quality of life and engaged in lessphysical activity (P < 0.05). Physical activity was a mediator in the relationship between pain and quality of life(6.5 %). This study confirms an association between pain and quality of life and highlights physical activ-ity as an essential component of this relationship; further research is needed to understand the mechanism of this relationship.

Pain Severity and Depressive Symptoms in Endometriosis Patients: Mediation of Negative Body Awareness and Interoceptive Self-Regulation

Endometriosis-related pain may be associated with depressive symptoms. Although a growing body of evidence supports this association, the underlying mechanisms are still largely unclear. Impaired perceptions of bodily external and internal stimuli may be involved in this process. This study aims to assess the mediating role of 2 facets of interoception-the awareness of negative body signals and interoceptive self-regulation-in the association between pain severity and depressive symptoms among women with endometriosis. A total of 301 patients who reported a diagnosis of endometriosis were recruited from an endometriosis and chronic pelvic pain outpatient university clinic and through patient associations and completed self-reported instruments. A parallel mediation analysis was conducted. Almost half of women (48.2%) reported depressive symptoms above the self-rating scale cutoff values. Pain severity significantly predicted depressive symptoms (β = .39, 95% bootstrap confidence interval [CI] [.719, 1.333]). Negative body awareness (β = .121, 95% bootstrap CI [.174, .468]) and interoceptive self-regulation (β = .05, 95% bootstrap CI [.035, .252]) partially mediated this relationship. Our findings indicated that pain may interfere with the perception of the body as a source of calmness and safety, limiting the individual's ability to effectively regulate emotions. Future research should further explore these mechanisms and evaluate the efficacy of interventions focusing on interoceptive sensibility to enhance the psychological well-being of endometriosis patients. PERSPECTIVE: This article investigates for the first time the potential role of 2 facets of interoceptive sensibility in the relationship between pain severity and depressive symptoms in women with endometriosis. These findings may contribute to advancing knowledge about the mechanisms involved in the complex pain-depression cycle.

Perspectives of people with spinal cord injury on a pain education resource

Introduction

Spinal cord injury (SCI) often leads to neuropathic pain that negatively affects quality of life. Several qualitative research studies in individuals with SCI who experience neuropathic pain indicate the lack of adequate information about pain. We previously developed an educational resource, the SeePain, based on scientific literature and a series of qualitative interviews of people with SCI, their significant others/family members, and SCI healthcare providers.

Methods

However, to quantitatively evaluate the utility of this educational resource in a larger sample, we examined the agreement and usefulness ratings of statements regarding clarity/comprehensibility, content, and format of the SeePain, derived from the thematic analysis of our previous qualitative interviews. Participants completed a survey that provided a digital version of the SeePain and then rated their agreement/usefulness with the statements using numerical rating scales.

Results

There were overall high perceived agreement and usefulness ratings regarding the SeePain's clarity, content, and format. A factor analysis reduced the agreement and usefulness ratings into 4 components (content, clarity, format, and delivery medium). Group comparisons showed that individuals with higher education were more likely to endorse electronic and website formats, and the usefulness of a shorter version of the SeePain; females and younger individuals showed greater endorsement for clarity. Finally, higher pain intensity ratings were associated with greater agreement and usefulness of the content of the SeePain.

Discussion

Overall, these results support the utility of the SeePain as a source of information regarding pain that may facilitate communication about pain and its management following SCI.

A Network Analysis of the Fear Avoidance Model of Genital Pain

Using a novel data-driven network approach, this study aimed to examine the interconnection between the key elements of the Fear-Avoidance Model of female genital pain - sexual arousal, fear-avoidant cognitions, and motivational coping - and its associated factors to predict the intensity and frequency of genital pain across women over time. Network modeling allowed for a comprehensive evaluation of the Fear-Avoidance model while capturing the dynamic features of genital pain. We estimated a cross-sectional and a temporal, contemporaneous, and between-persons network model on convenience-based data of 543 female students (mean age = 23.7 years, SD = 3.6) collected at three time points. Results showed that lubrication, pain catastrophizing, pain avoidance, fear-avoidance beliefs, sexual satisfaction, anxiety, and frequency of coital and non-coital sex predicted pain, with lubrication being the most consistent predictor across estimations. The network of women with recurrent genital pain showed a similar pattern as the network of the total sample, except that pain avoidance and fear-avoidance beliefs rather than pain catastrophizing predicted pain directly, and frequency of coital and non-coital sexual activities played a more prominent role. These results suggest that the main problem of genital pain centers around women not being sufficiently aroused during intercourse and inadequate ways of pain coping, which are critical targets of cognitive-behavioral therapy treatment and should be developed further.

Arthroscopy versus arthrocentesis and versus conservative treatments for temporomandibular joint disorders: a systematic review with meta-analysis and trial sequential analysis

The aim of this systematic review was to assess the efficacy of arthroscopy compared to arthrocentesis and to conservative treatments for temporomandibular joint disorders. Thirteen controlled studies on various patient outcomes were included after a systematic search in seven electronic databases. Meta-analyses were conducted separately for arthroscopic surgery (AS) and arthroscopic lysis and lavage (ALL), and short-term (<6 months), intermediate-term (6 months to 5 years), and long-term (≥5 years) follow-up periods were considered. No significant differences in pain reduction and complication rates were found between AS or ALL and arthrocentesis. Regarding improvement in maximum mouth opening (MMO), both AS at intermediate-term and ALL at short-term follow-up were equally efficient when compared to arthrocentesis. However, at intermediate-term follow-up, ALL was superior to arthrocentesis for MMO improvement (mean difference 4.9 mm, 95% confidence interval 2.7-7.1 mm). Trial sequential analysis supported the conclusion of the meta-analysis for MMO improvement for ALL versus arthrocentesis studies at intermediate-term follow-up, but not for the other meta-analyses. Insufficient evidence exists to draw conclusions regarding other patient outcomes or about comparisons between arthroscopy and conservative treatments. Due to the low quality of the primary studies, further research is warranted before final conclusions can be drawn regarding the management of temporomandibular joint disorders.

Experiential Avoidance as a Factor in Generalized Psychological Vulnerability: In the Relationship Between Chronic Pain and Pain Anxiety With Pain Disability

BACKGROUND

Pain is a major socio-psychological problem worldwide. Chronic pain has a negative effect on areas of psychological functioning such as depression, anxiety, and perceived stress.

AIM

The present study investigated the mediating role of experiential avoidance in the relationship between chronic pain and pain anxiety with pain disability.

METHODS

Participants were treatment-seeking patients (N = 361) at an outpatient pain clinic in Shiraz (Fars, Iran). The Multidimensional Pain Inventory (MPI), Pain Anxiety Symptom Scale (PASS-20), Pain Disability Questionnaire (PDQ), and Acceptance and Action Questionnaire-II (AAQ-II) were used to measure multidimensional pain, anxiety, pain disability, experiential avoidance, and pain severity.

RESULTS

The results of the correlation revealed that a significant relationship exists between multidimensional pain and pain anxiety, pain disability, and experiential avoidance. Experiential avoidance mediated the associations from multidimensional pain and pain disability significantly. Also, experiential avoidance moderated associations between pain anxiety and pain disability significantly. In general, Structural Equation Modeling (SEM) showed that experiential avoidance mediated the relationship between multidimensional pain and pain anxiety with pain disability.

CONCLUSION

In general, the results revealed that experiential avoidance can mediate the relationship among pain, pain anxiety, and pain disability as a maladaptive regulation strategy. The results obtained from this study seem to introduce experiential avoidance as a vulnerability factor effectively.

Nursing students' empathic communication: Role in recognizing and treating chronic pain patients

OBJECTIVE

A substantial body of research supports what many nurses know from experience: empathy is at the heart of providing quality care. The major objective of this study was to identify unique mechanisms through which higher empathy translates into greater intentions to treat patients in pain employing novel methodology.

METHODS

Using an ecologically-valid scenario methodology, student nurses (N = 156) reviewed the narrative of a patient in chronic pain. They completed standard, valid measures of empathy toward the patient, perception of the patient's pain, and intention to provide pain-relieving treatment. Nursing student's personality traits were assessed and perception of patients' age and sex were experimentally manipulated.

RESULTS

Empathy was associated with higher intention to treat the patient in chronic pain irrespective of patients' age or sex. A moderated-mediation analysis confirmed that nursing students with higher empathy perceived the patient in the scenario as being in greater pain. This was correspondingly associated with higher intention to provide treatment. Nursing students' trait Extraversion was a moderator.

CONCLUSION

Empathy not only improves rapport between patients and providers but is related to intentions to provide pain-relieving treatment.

PRACTICE IMPLICATIONS

The clinical and educational importance of empathy in patient-provider relationships are discussed.

Psychometric properties and domains covered by patient-reported outcome measures used in trials assessing interventions for chronic pain

OBJECTIVES

To identify the patient-reported outcome measures (PROMs) used in clinical trials assessing interventions for chronic pain, describe their psychometric properties, and the clinical domains they cover.

STUDY DESIGN AND SETTING

We identified phase 3 or 4 interventional trials: on adult participants (aged >18 years), registered in clinicaltrials.gov between January 1, 2021 and December 31, 2022, and which provided "chronic pain" as a keyword condition. We excluded diagnostic studies and phase 1 or 2 trials. In each trial, one reviewer extracted all outcomes registered and identified those captured using PROMs. For each PROM used in more than 1% of identified trials, two reviewers assessed whether it covered the six important clinical domains from the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT): pain, emotional functioning, physical functioning, participant ratings of global improvement and satisfaction with treatment, symptoms and adverse events, and participant disposition (eg, adherence to medication). Second, reviewers searched PubMed for both the initial publication and latest review reporting the psychometric properties of each PROM and assessed their content validity, structural validity, internal consistency, reliability, measurement error, hypotheses testing, criterion validity, and responsiveness using published criteria from the literature.

RESULTS

In total, 596 trials assessing 4843 outcomes were included in the study (median sample size 60, interquartile range 40-100). Trials evaluated behavioral (22%), device-based (21%), and drug-based (10%) interventions. Of 495 unique PROMs, 55 were used in more than 1% trials (16 were generic pain measures; 8 were pain measures for specific diseases; and 30 were measures of other symptoms or consequences of pain). About 50% PROMs had more than 50% of psychometric properties rated as sufficient. Scales often focused on a single clinical domain. Only 25% trials measured at least three clinical domains from IMMPACT.

CONCLUSION

Half of PROMs used in trials assessing interventions for chronic pain had sufficient psychometric properties for more than 50% of criteria assessed. Few PROMs assessed more than one important clinical domain. Only 25% of trials measured more than 3/6 clinical domains considered important by IMMPACT.

Cognitive Therapy, Mindfulness-Based Stress Reduction, and Behavior Therapy for the Treatment of Chronic Pain: Predictors and Moderators of Treatment Response

Psychosocial interventions for people with chronic pain produce significant improvements in outcomes, but these effects on average are modest with much variability in the benefits conferred on individuals. To enhance the magnitude of treatment effects, characteristics of people that might predict the degree to which they respond more or less well could be identified. People with chronic low back pain (N = 521) participated in a randomized controlled trial which compared cognitive therapy, mindfulness-based stress reduction, behavior therapy and treatment as usual. Hypotheses regarding predictors and/or moderators were based on the Limit, Activate, and Enhance model; developed to predict and explain moderators/predictors of psychosocial pain treatments. Results were: 1) low levels of cognitive/behavioral function at pre-treatment predicted favorable pre- to post-treatment outcomes; 2) favorable expectations of benefit from treatment and sound working alliances predicted favorable pre- to post-treatment outcomes; 3) women benefited more than men. These effects emerged without regard to treatment condition. Of note, high levels of cognitive/behavioral function at pre-treatment predicted favorable outcomes only for people in the treatment as usual condition. Analyses identified a set of psychosocial variables that may act as treatment predictors across cognitive therapy, mindfulness-based stress reduction and behavior therapy, as hypothesized by the Limit, Activate, and Enhance model if these 3 treatments operate via similar mechanisms. Findings point toward people who may and who may not benefit fully from the 3 psychosocial treatments studied here, and so may guide future research on matching people to these kinds of psychosocial approaches or to other (eg, forced-based interventions) non-psychosocial approaches. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT02133976. PERSPECTIVE: This article examines potential predictors/moderators of response to psychosocial treatments for chronic pain. Results could guide efforts to match people to the most effective treatment type or kind.

Prognostic subgroups of chronic pain patients using latent variable mixture modeling within a supervised machine learning framework

The present study combined a supervised machine learning framework with an unsupervised method, finite mixture modeling, to identify prognostically meaningful subgroups of diverse chronic pain patients undergoing interdisciplinary treatment. Questionnaire data collected at pre-treatment and 1-year follow up from 11,995 patients from the Swedish Quality Registry for Pain Rehabilitation were used. Indicators measuring pain characteristics, psychological aspects, and social functioning and general health status were used to form subgroups, and pain interference at follow-up was used for the selection and the performance evaluation of models. A nested cross-validation procedure was used for determining the number of classes (inner cross-validation) and the prediction accuracy of the selected model among unseen cases (outer cross-validation). A four-class solution was identified as the optimal model. Identified subgroups were separable on indicators, predictive of long-term outcomes, and related to background characteristics. Results are discussed in relation to previous clustering attempts of patients with diverse chronic pain conditions. Our analytical approach, as the first to combine mixture modeling with supervised, targeted learning, provides a promising framework that can be further extended and optimized for improving accurate prognosis in pain treatment and identifying clinically meaningful subgroups among chronic pain patients.

Optimising recovery after perineal trauma: Implementation of an evidence-based patient-centred care and clinical practice guideline

BACKGROUND

Perineal trauma and pain can affect the quality of life of women who experience vaginal birth.

AIM

To investigate the effect of perineal care and pain management on women's postpartum recovery.

METHODS

This was a Quasi-experimental study. In Phase 1 women were treated using our old postnatal perineal care management guideline. In Phase 2 an updated guideline was introduced (regular administration of icepacks and analgesia during the first 24-48 h postpartum). During Phase 1, pregnant women planning a vaginal birth completed a baseline questionnaire. Those who sustained perineal trauma completed a survey at 24-48 h, seven days and 12 weeks after birth. In Phase 2 we continued recruiting participants, using the same procedure, and investigated the efficacy of pain relief approaches using the new guideline.

RESULTS

In Phase 1, 111 women (Group 1), and Phase 2, 146 women (Group 2) were recruited. No statistically significant differences were found between the two groups in terms of the women's pain catastrophising, their partner's responses to pain behaviours, or birth outcomes. At 24-48 h and seven days postpartum, women in Group 2 were less likely than women in Group 1 to be bothered by back or perineal pain, headache, sleeping difficulties and dizziness (p < 0.05). More women in Group 2 received regular paracetamol and perineal icepacks during their hospital stay, with less use of oxycodone in Group 2 than Group 1.

CONCLUSION

The implementation of the guideline's recommendations was associated with decrease back and perineal pain, headache, sleeping difficulties and dizziness during the first seven days postpartum.

Biobehavior Life Regulation (BLR) scale for living well in chronic pain: Preliminary scale development and validation

Currently available pain assessment scales focus on pain-related symptoms and limitations imposed by pain. Validated assessment tools that measure how pain is regulated by those who live well with pain are missing. This study seeks to fill this gap by describing the development and preliminary validation of the Biobehavior Life Regulation (BLR) scale. The BLR scale assesses engagement, social relatedness, and self-growth in the presence of chronic pain and the unpredictability of chronic pain. Sources for items included survivor strategies, patient experiences, existing scales, and unpredictable pain research. Review for suitability yielded 52 items. Validation measures were identified for engagement, social relatedness, self-growth, and unpredictability of pain. The study sample (n = 202) represented patients treated in the Phoenix VA Health Care System (n = 112) and two community clinics (n = 90). Demographic characteristics included average age of 52.5, heterogeneous in ethnicity and race at the VA, mainly Non-Hispanic White at the community clinics, 14 years of education, and pain duration of 18 years for the VA and 15.4 years for community clinics. Exploratory factor analysis using Oblimin rotation in the VA sample (n = 112) yielded a two-factor solution that accounted for 48.23% of the total variance. Confirmatory factor analysis (CFA) in the same sample showed high correlations among items in Factor 1, indicating redundancy and the need to further reduce items. The final CFA indicated a 2-factor solution with adequate fit to the data. The 2-factor CFA was replicated in Sample 2 from the community clinics (n = 90) with similarly adequate fit to the data. Factor 1, Pain Regulation, covered 8 items of engagement, social relatedness, and self-growth while Factor 2, Pain Unpredictability, covered 6 items related to the experience of unpredictable pain. Construct validity showed moderate to higher Pearson correlations between BLR subscales and relevant well-established constructs that were consistent across VA and community samples. The BLR scale assesses adaptive regulation strategies in unpredictable pain as a potential tool for evaluating regulation resources and pain unpredictability.

Effects of Receiving Pain-Related Support on Psychological Well-Being: The Moderating Roles of Emotional Responses to Support

OBJECTIVES

We investigated whether receiving greater pain-related instrumental support is associated with poorer psychological well-being among chronic pain patients who report less positive (e.g., grateful) or more negative (e.g., angry) emotional responses to support.

METHODS

We conducted regression analyses, utilizing data from two waves of interviews with 152 knee osteoarthritis patients. Three indicators of psychological well-being were examined: depressive symptoms, positive affect, and negative affect.

RESULTS

Receiving greater support was associated with poorer psychological well-being at baseline, as well as higher depressive symptoms and negative affect at the 18-month follow-up, only among patients with low positive emotional responses to support. Furthermore, receiving greater support was related to poorer psychological well-being at baseline only among patients with high negative emotional responses to support.

DISCUSSION

Care recipients' less positive emotional responses to support may be a risk factor for poorer psychological well-being in both the short- and long-term, when receiving greater support.

My Catastrophizing and Your Catastrophizing: Dyadic Associations of Pain Catastrophizing and the Physical, Psychological, and Relational Well-being of Persons With Endometriosis and Their Partners

OBJECTIVES

Endometriosis, a painful chronic gynecologic condition, contributes to disruptions in multiple areas of life for both those affected and their partner. Pain catastrophizing has been associated with worse pain outcomes and quality of life for women with endometriosis and with more cognitive load for partners. Examining both partners' pain catastrophizing dyadically with our variables of interest will enhance understanding of its associations with the distressing nature of experiencing and responding to pain during sex for couples with endometriosis.

METHODS

Persons with endometriosis experiencing pain during sex and their partners (n=52 couples; 104 individuals) completed online self-report measures of pain catastrophizing, depressive symptoms, sexual satisfaction, and partner responses to pain. Persons with endometriosis reported on pain during sexual activity. Analyses were guided by the Actor-Partner Interdependence Model.

RESULTS

Persons with endometriosis' pain catastrophizing was associated with their higher pain intensity and unpleasantness during sex. When persons with endometriosis reported more pain catastrophizing, they were less sexually satisfied and reported their partners responded more negatively to their pain. When partners reported higher catastrophizing, they were more depressed and responded more negatively to the pain.

DISCUSSION

Consistent with the Communal Coping Model of pain catastrophizing, although meant to elicit support from the environment, the often-deleterious cognitive process of magnifying, ruminating, and feeling helpless about one's pain (or one's partner's pain) is associated with poorer outcomes for the individual with pain and their romantic partner. Implications for pain management include the relevance of involving the partner and attending to the pain cognitions of both members of the couple.

The contribution of pain catastrophizing, depression and anxiety symptoms among patients with persistent pain and opioid misuse behaviours

BACKGROUND

Anxiety, depression and pain catastrophizing are independently associated with risk of opioid misuse in patients with persistent pain but their relationship to current opioid misuse, when considered together, is poorly understood. This study will assess the relative contribution of these modifiable, and distinct psychological constructs to current opioid misuse in patients with persistent pain.

METHODS

One hundred and twenty-seven patients referred to a specialized opioid management clinic for prescription opioid misuse within a tertiary pain service were recruited for this study. The Pain Catastrophizing Scale, Depression, Anxiety and Stress Scales and the Current Opioid Misuse Measure were administered pre-treatment. Pain severity and morphine equivalent dose based on independent registry data were also recorded.

RESULTS

Higher levels of pain catastrophizing, depression, and anxiety were significantly associated with higher current opioid misuse (r = .475, 0.599, and 0.516 respectively, p < .01). Pain severity was significantly associated with pain catastrophizing (r = .301, p < .01). Catastrophizing, depression, and anxiety explained an additional 11.56% of the variance (R2 change = 0.34, p < .01) over and above age, gender, pain severity and morphine equivalent dose. Depression was the only significant variable at Step 2 (β = 0.62, p < .01).

CONCLUSION

Findings show that in a sample of people with persistent pain referred for treatment for opioid misuse, depression contributes over and above that of anxiety and pain catastrophizing. Theoretical and clinical practice implications are presented.

Orthopaedic Hand Patient Support Systems Have Valuable Insight to Patient Function and Pain

Patient-reported outcome measures (PROs) are increasingly used in clinical assessment. Research on how patient support systems contribute to physician understanding of patient condition is limited. Thus, insights from significant others may provide value, especially when concerns exist regarding patient response validity. Patients recruited from the pre-operative environment undergoing orthopaedic hand procedures responded to PROMIS-Pain Interference (PI), PROMIS-Upper Extremity (UE), PROMIS-Depression (D), and QuickDASH. They then selected a significant other (SO) to do the same. Patients and SOs were also asked to complete the West Haven-Yale Multidimensional Pain Inventory (WHYMPI) as a measure of support-related responses. Patient and SO responses were compared, and support-related responses were added in subsequent analyses to examine their effect on SO PRO assessment.

Development and Initial Validation of the First Questionnaire to Evaluate Performance-related Pain Among Musicians with Different Backgrounds: Performance-related Pain Among Musicians Questionnaire (PPAM)

AIM

To develop and perform the expert's content validation and pretesting of the first questionnaire specifically designed to evaluate performance-related pain among musicians with different backgrounds.

METHODS

The development of the Performance-related Pain Among Musicians Questionnaire (PPAM) was carried out in 4 phases: (1) item generation, (2) experts' panel evaluation and content validation (3) pretesting, and (4) conceptualization of the final version. For item generation we conducted two systematic reviews to identify the existing tools evaluating similar constructs and the predictive factors of performance-related pain. Four expert panel meetings and three pilot tests were performed, with a total of 94 musicians.

RESULTS

From the 1154 articles initially found in the literature search, 153 were included (65 related to pain tools and 88 related to predictive factors) and a pool of 115 items were created. After expert panel evaluation and pretesting, a final self-report questionnaire was defined, comprising 33 core items to evaluate 3 constructs (pain intensity, pain interference in general activities and pain interference in performance), as well as 32 additional items (optional module - predictive factors).

CONCLUSIONS

The PPAM Questionnaire is specifically designed and validated for musicians and can be applied for all types of musicians (professional, amateur and music students), allowing the development of comparative studies between musicians. It is a new enriched tool, easy to respond and disseminate to large, multicentre, and international samples. PPAM is suitable for research and clinical practice purposes and will allow the improved assessment and monitoring of pain in this occupational context.

The Contribution of Psychological Symptoms to Cognitive Difficulties in Youth With Postural Orthostatic Tachycardia Syndrome and Chronic Pain

INTRODUCTION

Subjectively experienced cognitive difficulties are common in youth with postural orthostatic tachycardia syndrome. The pathophysiological and psychological contributions of these cognitive impairments remain unclear.

METHOD

Participants were 96 adolescents and young adults diagnosed with postural orthostatic tachycardia syndrome and admitted to an intensive pain treatment program. Participants completed cognitive assessment and measures of postural orthostatic tachycardia syndrome symptoms, pain intensity, pain catastrophizing, anxiety, depression, and functional disability.

RESULTS

Self-reported autonomic symptom intensity, but not severity of heart rate change, was associated with cognitive performance. Symptoms of depression were associated with decreases in most measures of cognitive functioning. Pain intensity, pain catastrophizing, and depression but not cognitive scores and physiological measures, were significant predictors of disability.

CONCLUSION

Depression appears to be a significant contributor to the cognitive difficulties in youth with postural orthostatic tachycardia syndrome. These findings highlight the importance of assessing and treating affective symptoms in this population along with medical and lifestyle approaches to treating postural orthostatic tachycardia syndrome symptoms.

The mediating role of posttraumatic stress disorder symptoms in pain cognitions among Veterans with chronic pain

Symptoms of posttraumatic stress disorder (PTSD) are highly prevalent among Veterans with chronic pain. Considerable research has examined the intersection of chronic pain and PTSD symptoms. However, it remains unclear whether changes in PTSD may potentially serve a mechanistic role in improving unhelpful pain cognitions for individuals with chronic pain. The present research contributes to the foundational knowledge by addressing this question. Baseline data from a randomized controlled trial targeting pain-related disability for Veterans (n = 103; mean age 43.66; SD = 10.17) with musculoskeletal pain and depression and/or PTSD symptoms were used. Cross-sectional mediation analyses showed that PTSD symptoms mediated the relationship between pain severity and pain catastrophizing, and between pain severity and pain acceptance. After controlling for depression, the mediation involving pain catastrophizing remained significant, while the mediation for pain acceptance did not. Although limitations exist, results point to several treatment recommendations, including ensuring that depressive affect, PTSD-specific symptoms, and attention to both body and mind are included in treatment. Results also provide preliminary evidence for examining these associations longitudinally to improve our understanding of this population and corresponding treatment recommendations.

Benefits, Recruitment, Dropout, and Acceptability of the Strength Back Digital Health Intervention for Patients Undergoing Spinal Surgery: Nonrandomized, Qualitative, and Quantitative Pilot Feasibility Study

BACKGROUND

Patients undergoing spinal surgery report high levels of insecurity, pain, stress, and anxiety before and after surgery. Unfortunately, there is no guarantee that surgery will resolve all issues; postsurgical recovery often entails moderate to severe postoperative pain, and some patients undergoing spinal surgery do not experience (long-term) pain relief after surgery. Therefore, focusing on sustainable coping skills and resilience is crucial for these patients. A digital health intervention based on acceptance and commitment therapy (ACT) and positive psychology (PP) was developed to enhance psychological flexibility and well-being and reduce postsurgical pain.

OBJECTIVE

The objective of this study was 3-fold: to explore the potential benefits for patients undergoing spinal surgery of the digital ACT and PP intervention Strength Back (research question [RQ] 1), explore the feasibility of a future randomized controlled trial in terms of recruitment and dropout (RQ 2), and assess the acceptability of Strength Back by patients undergoing spinal surgery (RQ 3).

METHODS

We used a nonrandomized experimental design with an intervention group (n=17) and a control group (n=20). To explore the potential benefits of the intervention, participants in both groups filled out questionnaires before and after surgery. These questionnaires included measurements of pain intensity (Numeric Pain Rating Scale), pain interference (Multidimensional Pain Inventory), anxiety and depression (Hospital Anxiety and Depression Scale), valued living (Engaged Living Scale), psychological flexibility (Psychological Inflexibility in Pain Scale), and mental well-being (Mental Health Continuum-Short Form). Semistructured interviews combined with log data and scores on the Twente Engagement With eHealth Technologies Scale were used to assess the acceptability of the intervention.

RESULTS

A significant improvement over time in emotional (V=99; P=.03) and overall (V=55; P=.004) well-being (Mental Health Continuum-Short Form) was observed only in the intervention group. In addition, the intervention group showed a significantly larger decline in pain intensity (Numeric Pain Rating Scale) than did the control group (U=75; P=.003). Of the available weekly modules on average 80% (12/15) was completed by patients undergoing spinal fusion and 67% (6/9) was completed by patients undergoing decompression surgery. A total of 68% (17/25) of the participants used the intervention until the final interview. Most participants (15/17, 88%) in the intervention group would recommend the intervention to future patients.

CONCLUSIONS

This pilot feasibility study showed that combining ACT and PP in a digital health intervention is promising for patients undergoing spinal surgery as the content was accepted by most of the participants and (larger) improvements in pain intensity and well-being were observed in the intervention group. A digital intervention for patients undergoing (spinal) surgery can use teachable moments, when patients are open to learning more about the surgery and rehabilitation afterward. A larger randomized controlled trial is now warranted.

The relationship of affective and bodily states with goals and plans to increase physical activity: An 8-day study in students

Planning is an important tool to translate intentions into physical activity (PA) behavior. Affective and bodily states are known to influence how much PA individuals perform, but their impact on to formulation of PA plans is not yet known. The aim of the current study is to explore the effect of within- and between-subject variations in affective and bodily states on the content of PA goals and plans. Over eight consecutive days, 362 students created action and coping plans to achieve their daily PA goals. They also reported their affective and bodily states. Generalized linear mixed effect models were used to analyze the associations between these states and the content of the goals and plans. The results showed that both between- and within-subject variations in affective and bodily states were associated with goals formulated in terms of minutes, the intensity and context of planned activities, and anticipated barriers, though more effects were found for within-subject differences. Affective and bodily states impact daily PA goals and plans, highlighting the dynamic nature of planning. Our findings can be a first step toward personalized suggestions for goals, action plans, and coping strategies that are based on individual affective and bodily states.

Factors associated with racial and ethnic disparities in chronic pain after acute traumatic injury

BACKGROUND

Chronic pain represents a substantial health burden and source of disability following traumatic injury. This study investigates factors associated with racial and ethnic disparities in chronic pain.

METHODS

Prospective, longitudinal, panel study. Seriously injured patients were recruited from two trauma centres in the Northeastern and Southwestern USA. Data from medical records and individual surveys were collected in-hospital, and at 3-month and 12-month postinjury from a balanced cohort of non-Hispanic black, non-Hispanic white and Hispanic patients. We used linear regression to estimate the associations between race and ethnicity and 3-month and 12-month pain severity outcomes. We grouped all available cohort data on factors that theoretically influence the emergence of chronic pain after injury into five temporally ordered clusters and entered each cluster sequentially into regression models. These included: participant race and ethnicity, other demographic characteristics, preinjury health characteristics, acute injury characteristics and postinjury treatment.

RESULTS

650 participants enrolled (Hispanic 25.6%; white 38.1%; black 33.4%). Black participants reported highest relative chronic pain severity. Injury-related factors at the time of acute hospitalisation (injury severity, mechanism, baseline pain and length of stay) were most strongly associated with racial and ethnic disparities in chronic pain outcomes. After controlling for all available explanatory factors, a substantial proportion of the racial and ethnic disparities in chronic pain outcomes remained.

CONCLUSION

Racial and ethnic disparities in chronic pain outcomes may be most influenced by differences in the characteristics of acute injuries, when compared with demographic characteristics and postacute treatment in the year after hospitalisation.

THE USE OF DENTAL PATIENT-REPORTED OUTCOMES AMONG COMPARATIVE OBSERVATIONAL STUDIES IN ORTHODONTICS: A METHODOLOGICAL STUDY

OBJECTIVE

To identify and summarize the presence and characteristics of dental patient-reported outcomes (dPROs) and dental patient-reported outcome measures (dPROMs) within comparative observational studies published in 5 leading orthodontic journals.

METHODS

Electronic searching was performed to identify intervention (therapeutic or preventive) related comparative observational studies published in selected journals between 2015 and 2021. Two authors extracted the characteristics of each included study independently and in duplicate and summarized the dPROs and dPROMs used in these studies. All dPROs were classified into 2 general types (oral health-related quality of life [OHRQoL] and others), while dPROMs were divided into 3 categories (single-item questionnaires, generic multiple-item questionnaires, and specific multiple-item questionnaires). In addition, dPROMs were examined, if they evaluated the 4 dimensions of OHRQoL (oral function, orofacial pain, orofacial appearance, and psychosocial impact).

RESULTS

A total of 683 observational studies were eligible and included of which 117 (17.1%) used dPROs and dPROMs. Seven different dPROs (OHRQoL, patients' satisfaction with treatment, preferences, concerns, compliance, duration, and unwanted events) and 33 different dPROMs (including 8 single-item questionnaires, 11 generic multiple-item questionnaires, and 14 specific multiple-item questionnaires) were identified in these studies. OHRQoL was the most commonly used dPRO (92/117, 78.6%), while Oral Health Impact Profile 14 (OHIP-14) was the most frequently used dPROM (20/92, 21.7%). In terms of study design, cross-sectional studies had the highest proportion of dPRO usage (62/148, 41.9%), followed by cohort studies (63/505, 12.5%) and case-control studies (1/30, 3.3%).

CONCLUSIONS

Only one-sixth of comparative observational studies published in leading orthodontic journals could reflect patients' perspectives. Observational studies in orthodontics need to provide more patient-important information through the use of dPROs and dPROMs.

Dependency, Detachment, and Health-Related Behavior in Adult Primary Care Patients

This investigation examined links between three related personality styles as assessed with the Relationship Profile Test-destructive overdependence, dysfunctional detachment, and healthy dependency-and indices of health and health-related behavior in a mixed-sex (74% female) sample of 100 primary care patients with a mean age of 38.62 (SD = 12.99). Fourteen primary care physicians also participated. As hypothesized, destructive overdependence and dysfunctional detachment scores were positively correlated with number of contacts with the emergency department; healthy dependency scores were inversely related to emergency department contacts and number of overnight hospitalizations. Healthy dependency scores were associated with an array of positive health behaviors; destructive overdependence scores were negatively associated with positive health behaviors. In addition, healthy dependency scores were inversely related to physician ratings of a difficult doctor-patient relationship. These results demonstrate that destructive overdependence, dysfunctional detachment and healthy dependency scores are associated in expected ways with indices of health and health-related behavior, and help illuminate the underlying factors that contribute to comparatively poor health and variations in health service use among overdependent and detached medical patients.

Psychological Treatment Targeting Acceptance and Compassion in Patients With Chronic Pain: A Randomized Controlled, Internet-delivered, Treatment Trial

OBJECTIVES

Chronic pain is often associated with lower function. Self-criticism is associated with depressive symptoms. The purpose of this study was to explore if fusing Acceptance and Commitment Therapy and compassion-focused therapy could improve psychological well-being and disability in individuals with chronic pain with high levels of self-criticism in comparison to a wait-list control group.

METHODS

Individuals with chronic pain (n=71) were randomly assigned to an 8-week internet-based intervention focused on acceptance and compassion or a wait-list condition. Primary treatment outcomes were the Chronic Pain Acceptance Questionnaire, Self-Compassion Scale, and Pain Disability Index. Secondary outcomes were the Montgomery Åsberg Depression Rating Scale, Anxiety Sensitivity Index, Quality of Life Inventory, Multidimensional Pain Inventory, and Perseverative Thinking Questionnaire.

RESULTS

Missing data at postintervention were 22.5%. Intention-to-treat analyses were conducted using linear mixed models. The results revealed greater levels of acceptance and self-compassion for the treatment group, which were primary outcomes, with effect sizes ranging from small to large, and these results were maintained at 6-month follow-up. The rates of clinically significant improvements were also greater for the treatment group in comparison to the wait-list control group on acceptance and compassion. The treatment group also improved in the third primary outcome, pain disability. Significant differences were found in several of the secondary outcomes, in favor of the treatment group.

DISCUSSION

Internet-based Acceptance and Commitment Therapy with compassion-focused therapy components shows promise as a viable treatment option in the management of chronic pain.

Shifting quality chronic pain treatment measures from processes to outcomes

OBJECTIVE

Misapplication of the 2016 Centers for Disease Control (CDC) opioid prescribing guidelines has led to overem-phasis of morphineequivalent daily dose (MEDD) as a "metric of success" in chronic noncancer pain (CNCP), resulting in unintentional harms to patients. This article reviews CNCP-related guidelines and patient preferences in order to identify pragmatic, patient-centered metrics to assess treatment response and safety in opioid-treated CNCP.

METHODS

We reviewed the clinical (CDC), research (Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials), and implementability-related guidelines (GuideLine Implementability Appraisal), along with relevant patient-identified treatment goals. From these, we summarize a guideline-concordant, patient-centered, implementable set of measures to aid the clinical management of opioid-treated CNCP.

RESULTS

We identify metrics across three domains of care: (1) treatment response metrics, which align with the CNCP care goals (pain intensity, pain interference including function and quality of life, and global impression of change); (2) risk assessment ("safety") metrics, eg, MEDD, benzodiazepine-opioid or naloxone-opioid coprescribing, and severity of mental health disorders, which evaluate the risk-benefit profile of opioid therapy; and (3) adherence ("process") metrics, which assess clinician/patient adherence to the guideline-recommended opioid therapy monitoring practices, eg, the presence of completed treatment agreement or urine toxicology testing. All metrics should be informed by implementability principles, eg, be decidable, executable, and measurable.

CONCLUSIONS

This article summarizes guideline-concordant, patient-centered, implementable metrics for assessing treatment response, safety, and adherence in opioid-treated CNCP. Regardless of which specific treatment guidelines are applied, this approach could help conceptualize and standardize the collection and reporting of CNCP-relevant metrics, compare them across health systems, and optimize care and treatment outcomes in opioid-treated CNCP.

Effect on orofacial pain in patients with chronic pain participating in a multimodal rehabilitation programme - a pilot study

OBJECTIVES

Orofacial pain in patients taking part in a multimodal rehabilitation programme (MMRP) due to chronic bodily pain is common but it is not known whether such a rehabilitation programme can also have an effect on the presence of orofacial pain. The first aim of this study was to evaluate the effect of an MMRP on orofacial pain frequency. The second aim was to evaluate differences in the effect on quality of life and on psychosocial factors related to chronic pain.

METHODS

MMRP was evaluated through validated questionnaires from the Swedish Quality Registry for Pain Rehabilitation (SQRP). Fifty-nine patients participating in MMRP filled out the two screening questions for orofacial pain in addition to the SQRP questionnaires before and after participation in MMRP during the period August 2016 to March 2018.

RESULTS

Pain intensity decreased significantly after the MMRP (p=0.005). Fifty patients (69.4 %) reported orofacial pain before MMRP and no significant decrease after the programme (p=0.228). Among individuals with orofacial pain, the self-reported level of depression decreased after participation in the programme (p=0.004).

CONCLUSIONS

Even though orofacial pain is common among patients with chronic bodily pain, participation in a multimodal pain programme was not enough to reduce frequent orofacial pain. This finding implies that specific orofacial pain management including information about jaw physiology could be a justified component of patient assessment prior to a multimodal rehabilitation programme for chronic bodily pain.

Interpersonal Experiences with Persistent Genital Arousal: Connections between Symptom Disclosure, Partner Responses, and Catastrophizing on Relationship Adjustment and Symptom Severity

Increased research attention to interpersonal factors in genitopelvic pain conditions, such as vulvodynia, have led to more comprehensive understanding of couple dynamics in pain, sexual, and relationship outcomes. There has been very little examination of interpersonal factors in Persistent Genital Arousal Disorder/Genitopelvic Dysesthesia (PGAD/GPD), a distressing condition involving persistent sensations of arousal and often pain. The aims of the present study were to examine whether individuals disclose their symptoms to intimate partners and whether interpersonal variables (e.g., partner responses, symptom disclosure, and catastrophizing) are related to relationship adjustment and symptom severity. Seventy-six individuals with symptoms of PGAD/GPD participated in a one-time anonymous online survey. Over three-quarters (85.5%) of the sample disclosed their symptoms to their partners in some way. Greater supportive partner responses and lower symptom catastrophizing were related to better relationship adjustment among participants with PGAD/GPD symptoms. Greater symptom catastrophizing also predicted greater PGAD/GPD symptom severity. Partner responses were not related to PGAD/GPD symptom severity. Although interpersonal factors have been linked to symptom severity in chronic pain and genitopelvic pain conditions, the results of the current study suggest that interpersonal factors may play a slightly different role in PGAD/GPD symptom experiences and in the conceptualization of PGAD/GPD more broadly.

Identifying chronic low back pain phenotypic domains and characteristics accounting for individual variation: a systematic review

ABSTRACT

Interpatient variability is frequently observed among individuals with chronic low back pain (cLBP). This review aimed at identifying phenotypic domains and characteristics that account for interpatient variability in cLBP. We searched MEDLINE ALL (through Ovid), Embase Classic and EMBASE (through Ovid), Scopus, and CINAHL Complete (through EBSCOhost) databases. Studies that aimed to identify or predict cLBP different phenotypes were included. We excluded studies that focused on specific treatments. The methodological quality was assessed using an adaptation of the Downs and Black tool. Forty-three studies were included. Although the patient and pain-related characteristics used to identify phenotypes varied considerably across studies, the following were among the most identified phenotypic domains and characteristics that account for interpatient variability in cLBP: pain-related characteristics (including location, severity, qualities, and duration) and pain impact (including disability, sleep, and fatigue), psychological domains (including anxiety and depression), behavioral domains (including coping, somatization, fear avoidance, and catastrophizing), social domains (including employment and social support), and sensory profiling (including pain sensitivity and sensitization). Despite these findings, our review showed that the evidence on pain phenotyping still requires further investigation. The assessment of the methodological quality revealed several limitations. We recommend adopting a standard methodology to enhance the generalizability of the results and the implementation of a comprehensive and feasible assessment framework to facilitate personalized treatments in clinical settings.

The Roles of Depression, Life Control and Affective Distress on Treatment Attendance and Perceived Disability in Chronic Back Pain Sufferers throughout the Duration of the Condition

The aims of this study were to examine psychological factors that predict treatment seeking and disability over the total duration of experiencing back pain. A sample of 201 adults experiencing chronic back pain was recruited through health professionals and completed the Depression, Anxiety and Stress Scale (DASS), the Oswestry Back Pain Disability Questionnaire (ODQ), the McGill Pain Questionnaire (MPQ) and the life control and affective distress variables of the West Haven-Yale Multidimensional Pain Inventory (WHYMP), and participants disclosed the number of treatment sessions attended over the course of the illness. Depression, life control and affective distress were tested as indirect predictors of disability severity that were mediated by treatment attendance. Each unit increase in life control predicted attending nearly 30 more treatment sessions, each unit increase in affective distress predicted attending 16 fewer treatments and each unit increase in depression predicted 4 fewer treatments, together explaining 44% of variance in treatment seeking. The effects of life control and affective distress on disability were explained by treatment attendance, whereas depression retained a direct effect on disability. Treatment attendance had an effect on disability. The findings show that participants with lower life control and higher affective distress and depression had higher levels of pain and disability, in part due to due to their treatment-seeking behaviour.

Therapeutic Lifestyle Intervention Targeting Enhanced Cardiometabolic Health and Function for Persons with Chronic Spinal Cord Injury in Caregiver/Care-Receiver Co-Treatment: A Study Protocol of a Multisite Randomized Controlled Trial

BACKGROUND

Chronic spinal cord injury (SCI) significantly accelerates morbidity and mortality, partly due to the increased risk of cardiometabolic diseases (CMD), including neurogenic obesity, dyslipidemia, and impaired glucose metabolism. While exercise and dietary interventions have shown some transient benefits in reducing CMD risk, they often fail to improve clinically relevant disease markers and cardiovascular events. Moreover, SCI also places caregiving demands on their caregivers, who themselves experience health and functional decline. This underscores the need for more substantial interventions that incorporate appropriate physical activity, heart-healthy nutrition, and behavioral support tailored to the SCI population.

OBJECTIVES

This randomized clinical trial (RCT) protocol will (1) assess the health and functional effects, user acceptance, and satisfaction of a 6-month comprehensive therapeutic lifestyle intervention (TLI) adapted from the National Diabetes Prevention Program (DPP) for individuals with chronic SCI and (2) examine the impact of a complementary caregiver program on the health and function of SCI caregivers and evaluate user acceptance and satisfaction. Caregivers (linked with their partners) will be randomized to 'behavioral support' or 'control condition'.

METHODS

Dyadic couples comprise individuals with SCI (18-65 years, >1-year post-injury, ASIA Impairment Scale A-C, injury levels C5-L1) and non-disabled SCI caregivers (18-65 years). Both groups undergo lock-step circuit resistance training, a calorie-restricted Mediterranean-style diet, and 16 educational sessions focused on diet/exercise goals, self-monitoring, psychological and social challenges, cognitive behavioral therapy, and motivational interviewing. The outcome measures encompass the cardiometabolic risks, cardiorespiratory fitness, inflammatory stress, multidimensional function, pain, life quality, independence, self-efficacy, program acceptance, and life satisfaction for SCI participants. The caregiver outcomes include multidimensional function, pain, quality of life, independence, and perceived caregiver burden.

DISCUSSION/CONCLUSIONS

This study evaluates the effects and durability of a structured, multi-modal intervention on health and function. The results and intervention material will be disseminated to professionals and consumers for broader implementation.

Neuropsychological Function in Traumatic Brain Injury and the Influence of Chronic Pain

Cognitive dysfunction, pain, and psychological morbidity all present unique challenges to those living with traumatic brain injury (TBI). In this study we examined (a) the impact of pain across domains of attention, memory, and executive function, and (b) the relationships between pain and depression, anxiety, and post-traumatic stress disorder (PTSD) in persons with chronic TBI. Our sample included 86 participants with a TBI and chronic pain (n = 26), patients with TBI and no chronic pain (n = 23), and a pain-free control group without TBI (n = 37). Participants visited the laboratory and completed a comprehensive battery of neuropsychological tests as part of a structured interview. Multivariate analysis of covariance using education as a covariate, failed to detect a significant group difference for neuropsychological composite scores of attention, memory, and executive function (p = .165). A follow-up analysis using multiple one-way analysis of variance (ANOVA) was conducted for individual measures of executive function. Post-hoc testing indicated that those in both TBI groups preformed significantly worse on measures of semantic fluency when compared to controls (p < 0.001, ηρ2 = .16). Additionally, multiple ANOVAs indicated that those with TBI and pain scored significantly worse across all psychological assessments (p < .001). We also found significant associations between measures of pain and most psychological symptoms. A follow-up stepwise linear regression among those in the TBI pain group indicated that post concussive complaints, pain severity, and neuropathic pain symptoms differentially contributed to symptoms of depression, anxiety, and PTSD. These findings suggest deficits in verbal fluency among those living with chronic TBI, with results also reinforcing the multidimensional nature of pain and its psychological significance in this population.

The benefits of making peace with pain: chronic pain acceptance moderates the indirect effect of perceived burdensomeness between pain severity and suicidal cognitions

OBJECTIVE

The purpose of this study was (1) to examine the degree to which perceived burdensomeness mediates the relationship between pain severity and suicidal cognitions and (2) to determine whether this mediated relationship was moderated by pain acceptance. We predicted that high levels of pain acceptance would buffer relationships on both paths of the indirect effect.

METHODS

Two-hundred seven patients with chronic pain completed an anonymous self-report battery of measures, including the Chronic Pain Acceptance Questionnaire, the Interpersonal Needs Questionnaire, the Suicidal Cognitions Scale, and the pain severity subscale of the West Haven-Yale Multidimensional Pain Inventory. Conditional process models were examined with Mplus.

RESULTS

Chronic pain acceptance significantly moderated both paths of the mediation model. Results from the conditional indirect effect model indicated that the indirect effect was significant for those with low (b = 2.50, P = .004) and medium (b = 0.99, P = .01) but not high (b = 0.08, P = .68) levels of pain acceptance and became progressively stronger as pain acceptance scores decreased. The nonlinear indirect effect became nonsignificant at acceptance scores 0.38 standard deviation above the mean-a clinically attainable treatment target.

CONCLUSIONS

Higher acceptance mitigated the relationship between pain severity and perceived burdensomeness and the relationship between perceived burdensomeness and suicidal cognitions in this clinical sample of patients experiencing chronic pain. Findings indicate that any improvement in pain acceptance can be beneficial, and they provide clinicians with a clinical cut-point that might indicate lower vs higher suicide risk.

Relations between PTSD symptom clusters and pain in three trauma-exposed samples with pain

OBJECTIVES

Little is known about how the individual PTSD symptom clusters relate to intensity and interference of pain and whether these relationships differ across clinical groups. The present study examines relations between PTSD symptom clusters and pain in three trauma-exposed, unique clinical groups: 1) adults seeking treatment for chronic pain with current symptoms of PTSD, 2) trauma affected refugees seeking treatment for PTSD and chronic pain; and 3) individuals identified at admission to the emergency ward after whiplash injury.

METHODS

Network analysis was used to assess unique relations between pain intensity, pain interference, re-experiencing, avoidance, numbing, hyperarousal, depression, and anxiety separately in each sample. Links between PTSD clusters and pain were then compared within and between samples.

RESULTS

No within-group differences were identified for the links between pain and any of PTSD clusters in the chronic pain and refugee groups. In the whiplash group, hyperarousal was more strongly related to pain than re-experiencing, avoidance, and numbing. Between group comparisons revealed a more pronounced relationship between hyperarousal and pain in the whiplash group, with no between-group differences between the chronic pain and refugee groups.

CONCLUSIONS

The findings suggest that when depression and anxiety are accounted for, few unique associations are found between pain and the PTSD symptom clusters in trauma-exposed samples with pain, with the exception of a link between pain and hyperarousal in individuals with whiplash-related PTSD symptoms.

Development of a pain education resource for people with spinal cord injury

Many people with spinal cord injury (SCI) develop chronic pain, including neuropathic pain. Unfortunately, current treatments for this condition are often inadequate because SCI-associated neuropathic pain is complex and depends on various underlying mechanisms and contributing factors. Multimodal treatment strategies including but not limited to pharmacological treatments, physical rehabilitation, cognitive training, and pain education may be best suited to manage pain in this population. In this study, we developed an educational resource named the SeePain based on published pain literature, and direct stakeholder input, including people living with SCI and chronic pain, their significant others, and healthcare providers with expertise in SCI. The SeePain was then 1) systematically evaluated by stakeholders regarding its content, comprehensibility, and format using qualitative interviews and thematic analysis, and 2) modified based on their perspectives. The final resource is a comprehensive guide for people with SCI and their significant others or family members that is intended to increase health literacy and facilitate communication between SCI consumers and their healthcare providers. Future work will quantitatively validate the SeePain in a large SCI sample.

Outcomes of Osteoid Osteoma Treated by Percutaneous CT-Guided Radiofrequency Ablation

Introduction Osteoid osteomas are the most frequent true benign bone tumor in the adolescent age group and the third most prevalent benign bone tumor overall. This study was designed to assess the effectiveness of the procedure and correlate it with the analgesia offered because of the significant burden of this illness and new literature supporting the successful outcomes of image-guided percutaneous radiofrequency ablation (RFA) in osteoid osteoma. Methodology  This hospital-based interventional trial was carried out in a tertiary care referral center. Forty-two patients with osteoid osteoma, ranging in age from 9 to 30, were included in the study. The patients received RFA guided by computed tomography (CT), and they were postoperatively monitored at one, two, and four weeks and three, six months, and 12 months. A numerical pain scale (NPS) was used to evaluate the patient's pain both before and after the procedure. The preoperative and postoperative results were contrasted. Results A total of 42 participants were enrolled in the study. Eight (19.05%) women and 34 (80.95%) men made up the group. Complete pain alleviation (NPS=0) was attained in 42.8% and 96.4% of the study group in the first and second weeks post-procedure. Almost all patients began protected weight-bearing at one week, according to their level of pain tolerance. Osteoid osteoma of the talus was a remnant lesion in one patient that required further treatment after two weeks. During the duration of the follow-up, no problems were recorded. Conclusion Percutaneous CT-guided RFA of osteoid osteoma is a safe, minimally invasive procedure and greatly reduces the duration of hospitalization. It has excellent functional outcomes and no known complications.

MicroRNA-Related Polymorphism and Their Association with Fibromyalgia

MicroRNAs are tissue-specific expressed short RNAs that serve post-transcriptional gene regulation. A specific microRNA can bind to mRNAs of different genes and thereby suppress their protein production. In the context of the complex phenotype of fibromyalgia, we used the Axiom miRNA Target Site Genotyping Array to search genome-wide for DNA variations in microRNA genes, their regulatory regions, and in the 3'UTR of protein-coding genes. To identify disease-relevant DNA polymorphisms, a cohort of 176 female fibromyalgia patients was studied in comparison to a cohort of 162 healthy women. The association between 48,329 markers and fibromyalgia was investigated using logistic regression adjusted for population stratification. Results show that 29 markers had p-values < 1 × 10^-3, and the strongest association was observed for rs758459 (p-value of 0.0001), located in the Neurogenin 1 gene which is targeted by hsa-miR-130a-3p. Furthermore, variant rs2295963 is predicted to affect binding of hsa-miR-1-3p. Both microRNAs were previously reported to be differentially expressed in fibromyalgia patients. Despite its limited statistical power, this study reports two microRNA-related polymorphisms which may play a functional role in the pathogenesis of fibromyalgia. For a better understanding of the disease pattern, further functional analyses on the biological significance of microRNAs and microRNA-related polymorphisms are required.

A systematic review of the psychosocial factors associated with pain in children with juvenile idiopathic arthritis

BACKGROUND

Pain is one of the most frequently reported experiences amongst children with Juvenile Idiopathic Arthritis (JIA); however, the management of JIA pain remains challenging. As pain is a multidimensional experience that is influenced by biological, psychological, and social factors, the key to effective pain management lies in understanding these complex relationships. The objective of this study is to systematically review the literature on psychosocial factors of children with JIA and their caregivers 1) associated with and 2) predictive of later JIA pain intensity, frequency, and sensitivity in children 0-17 years of age.

METHODS

The Joanna Briggs Institute methodology for etiology and risk and Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement guided the conduct and reporting of this review. Terms related to pain and JIA were searched in English without date restrictions across various databases (PubMed, CINAHL, PsycINFO, Embase, Scopus, and the Cochrane Central Register of Controlled Trials) in September 2021. Two independent reviewers identified, extracted data from, and critically appraised the included studies. Conflicts were resolved via consensus.

RESULTS

Of the 9,929 unique studies identified, 61 were included in this review and reported on 516 associations. Results were heterogeneous, likely due to methodological differences and moderate study quality. Results identified predominantly significant associations between pain and primary and secondary appraisals (e.g., more child pain beliefs, lower parent/child self-efficacy, lower child social functioning), parent/child internalizing symptoms, and lower child well-being and health-related quality of life. Prognostically, studies had 1-to-60-month follow-up periods. Fewer beliefs of harm, disability, and no control were associated with lower pain at follow-up, whereas internalizing symptoms and lower well-being were predictive of higher pain at follow-up (bidirectional relationships were also identified).

CONCLUSIONS

Despite the heterogeneous results, this review highlights important associations between psychosocial factors and JIA pain. Clinically, this information supports an interdisciplinary approach to pain management, informs the role of psychosocial supports, and provides information to better optimize JIA pain assessments and interventions. It also identifies a need for high quality studies with larger samples and more complex and longitudinal analyses to understand factors that impact the pain experience in children with JIA.

Brain morphometric changes in fibromyalgia and the impact of psychometric and clinical factors: a volumetric and diffusion-tensor imaging study

BACKGROUND

Previous studies have repeatedly found distinct brain morphometric changes in patients with fibromyalgia (FM), mainly affecting gray and white matter abnormalities in areas related to sensory and affective pain processing. However, few studies have thus far linked different types of structural changes and not much is known about behavioral and clinical determinants that might influence the emergence and progression of such changes.

METHODS

We used voxel-based morphometry (VBM) and diffusion-tensor imaging (DTI) to detect regional patterns of (micro)structural gray (GM) and white matter (WM) alterations in 23 patients with FM compared to 21 healthy controls (HC), while considering the influence of demographic, psychometric, and clinical variables (age, symptom severity, pain duration, heat pain threshold, depression scores).

RESULTS

VBM and DTI revealed striking patterns of brain morphometric changes in FM patients. Bilateral middle temporal gyrus (MTG), parahippocampal gyrus, left dorsal anterior cingulate cortex (dACC), right putamen, right caudate nucleus, and left dorsolateral prefrontal cortex (DLPFC) showed significantly decreased GM volumes. In contrast, increased GM volume was observed in bilateral cerebellum and left thalamus. Beyond that, patients displayed microstructural changes of WM connectivity within the medial lemniscus, corpus callosum, and tracts surrounding and connecting the thalamus. Sensory-discriminative aspects of pain (pain severity, pain thresholds) primarily showed negative correlations with GM within bilateral putamen, pallidum, right midcingulate cortex (MCC), and multiple thalamic substructures, whereas the chronicity of pain was negatively correlated with GM volumes within right insular cortex and left rolandic operculum. Affective-motivational aspects of pain (depressive mood, general activity) were related to GM and FA values within bilateral putamen and thalamus.

CONCLUSIONS

Our results suggest a variety of distinct structural brain changes in FM, particularly affecting areas involved in pain and emotion processing such as the thalamus, putamen, and insula.

Fear network and pain extent: Interplays among psychological constructs related to the fear-avoidance model

OBJECTIVE

Psychological constructs related to the fear-avoidance model such as fear of movement, pain catastrophizing, and affective distress have been found to be inter-related among patients with chronic pain. However, relationships of these constructs have mostly been examined using regression-based analyses. This cross-sectional study employs a novel analytical approach, network analysis, to illustrate the complex interplays among these variables as well as pain intensity and pain interference.

METHODS

This study utilized the Swedish Quality Registry for Pain Rehabilitation, including data from 10,436 participants (76.0% women; M_age = 45.0 years). Networks were analyzed separately for patients with different pain extents (i.e., numbers of pain locations) as the interplays may differ qualitatively depending on pain extent.

RESULTS

We found that patients with a larger pain extent showed a worse clinical presentation (i.e., more depression and anxiety, increased fear of movement and pain interference), and their network differed from the patients with a smaller number of pain extent in terms of how strongly key variables were interconnected. In all network models, pain interference and catastrophizing showed consistently influential roles.

CONCLUSION

Our findings highlight the interactive nature of psychological aspects of pain and how interrelated associations differ depending on pain extent. Findings are discussed based on ideas on how both fear and pain become overgeneralized.

TFOS Lifestyle: Impact of lifestyle challenges on the ocular surface

Many factors in the domains of mental, physical, and social health have been associated with various ocular surface diseases, with most of the focus centered on aspects of dry eye disease (DED). Regarding mental health factors, several cross-sectional studies have noted associations between depression and anxiety, and medications used to treat these disorders, and DED symptoms. Sleep disorders (both involving quality and quantity of sleep) have also been associated with DED symptoms. Under the domain of physical health, several factors have been linked to meibomian gland abnormalities, including obesity and face mask wear. Cross-sectional studies have also linked chronic pain conditions, specifically migraine, chronic pain syndrome and fibromyalgia, to DED, principally focusing on DED symptoms. A systematic review and meta-analysis reviewed available data and concluded that various chronic pain conditions increased the risk of DED (variably defined), with odds ratios ranging from 1.60 to 2.16. However, heterogeneity was noted, highlighting the need for additional studies examining the impact of chronic pain on DED signs and subtype (evaporative versus aqueous deficient). With respect to societal factors, tobacco use has been most closely linked to tear instability, cocaine to decreased corneal sensitivity, and alcohol to tear film disturbances and DED symptoms.

Cognitive and mental fatigue in chronic pain: cognitive functions, emotional aspects, biomarkers and neuronal correlates-protocol for a descriptive cross-sectional study

INTRODUCTION

Chronic pain (CP) is one of the most frequently presenting conditions in health care and many patients with CP report mental fatigue and a decline in cognitive functioning. However, the underlying mechanisms are still unknown.

METHODS AND ANALYSIS

This study protocol describes a cross-sectional study aimed at investigating the presence of self-rated mental fatigue, objectively measured cognitive fatigability and executive functions and their relation to other cognitive functions, inflammatory biomarkers and brain connectivity in patients with CP. We will control for pain-related factors such as pain intensity and secondary factors such as sleep disturbances and psychological well-being. Two hundred patients 18-50 years with CP will be recruited for a neuropsychological investigation at two outpatient study centres in Sweden. The patients are compared with 36 healthy controls. Of these, 36 patients and 36 controls will undergo blood sampling for inflammatory markers, and of these, 24 female patients and 22 female controls, between 18 and 45 years, will undergo an functional MRI investigation. Primary outcomes are cognitive fatigability, executive inhibition, imaging and inflammatory markers. Secondary outcomes include self-rated fatigue, verbal fluency and working memory. The study provides an approach to study fatigue and cognitive functions in CP with objective measurements and may demonstrate new models of fatigue and cognition in CP.

ETHICS AND DISSEMINATION

The study has been approved by the Swedish Ethics Review Board (Dnr 2018/424-31; 2018/1235-32; 2018/2395-32; 2019-66148; 2022-02838-02). All patients gave written informed consent to participate in the study. The study findings will be disseminated through publications in journals within the fields of pain, neuropsychology and rehabilitation. Results will be spread at relevant national and international conferences, meetings and expert forums. The results will be shared with user organisations and their members as well as relevant policymakers.

Patient-reported outcome measurements (PROMs): Use during the physical therapy practice and associated factors

OBJECTIVE

To assess the current level of routine use of psychosocial-related patient-reported outcome measurements (PROMs) in physical therapy practice and which physical therapist-level factors are associated with the use of these measurement instruments.

METHODS

We conducted an online survey study among Spanish physical therapists involved in the treatment of LBP patients in Public Health Service, Mutual Insurance Companies, and private practice during 2020. Descriptive analyses were conducted for reporting the number and instruments utilized. Thus, sociodemographic and professional features differences between PTs using and not using PROM were analyzed.

RESULTS

From 485 physiotherapists completing the questionnaire nationwide, 484 were included. A minority of therapists routinely used psychosocial-related PROMs (13.8%) in LBP patients and only 6.8% did so through standardized measurements instruments. The Tampa Scale for Kinesiophobia (28.8%) and the Pain Catastrophizing Scale (15.1%) were used most frequently. Physiotherapists working in Andalucía and País Vasco regions, in private practice environments, educated in psychosocial factors evaluation and management, considering psychosocial factors during the clinical practice and expecting patients' collaborative attitudes demonstrated significantly greater use of PROMS (p < 0.05).

CONCLUSIONS

This study showed that the majority of physiotherapists in Spain do not use PROMs for evaluating LBP (86.2%). From those physiotherapists using PROMs, approximately the half use validated instruments such as the Tampa Scale for Kinesiophobia or the Pain Catastrophizing Scale while the other half limit their evaluation to anamnesis and non-validated questionnaires. Therefore, developing effective strategies to implement and facilitate the use of psychosocial-related PROMs would enhance the evaluation during the clinical practice.

Interaction analyses: Enhancing understanding of chronic low back pain

BACKGROUND

Chronic low back pain (CLBP) is complex. Statistical examination of influences of exposures (e.g. characteristics) upon outcomes (e.g. pain) facilitates understanding of complexity and personalized care. Psychological factors may be associated with higher disability following exercise in CLBP. Examining interactions of psychological variables with exercise on disability might further understanding of CLBP.

OBJECTIVES

Secondary analysis of data from a CLBP cohort evaluating interactions between psychological variables and exercise on disability.

DESIGN

Longitudinal cohort study.

METHOD

Variables from a published prognostic model for disability: disability (baseline/one-year follow-up), psychological principal component scores (principal component score two (PC2) - Fear-avoidance beliefs, pain catastrophizing, pain self-efficacy; principal component score three (PC3) - thought suppression, behavioral endurance), exercise (during follow-up), forward-bending time, punishing significant other responses. Differences between exercisers and non-exercisers were assessed using Chi-Squared/Mann-Whitney tests. Multivariable linear regression models for follow-up disability included a term examining interaction between principal component scores and exercise.

RESULTS

Exercisers had significantly different scores for PC2 (p = .02) and PC3 (p = .03), lower baseline (p = .005) and follow-up pain intensity (p < .001), follow-up disability (p < .001) and faster forward-bend times (p = .014). There was no significant interaction between exercise and PC2 (p = .92) or PC3 (p = .75).

CONCLUSIONS

This study showed no interaction between psychological factors and exercise on disability at follow-up. These findings suggest that the disability outcome of people with CLBP who undertake exercise as an intervention does not differ from those who do not undertake exercise, irrespective of their baseline psychological status.
