The impact of fear of attacks on pain-related disability in cluster headache: Insights from the fear avoidance model.

OBJECTIVE: This study utilized the theoretical framework of the "fear avoidance model" (FAM) and investigated the role of fear of attack in pain-related disability. To this end, a measurement specific to cluster headache (CH) was used to investigate whether fear of attacks, alongside attack frequency, is a significant predictor of pain-related disability in CH. BACKGROUND: Cluster headache substantially impacts daily functioning, yet empirical research exploring specific contributing factors is limited. METHODS: A cross-sectional online survey was undertaken in patients with CH, gathering sociodemographic, clinical data, and responses on the Cluster Headache Scale and the Depression, Anxiety and Stress Scale. RESULTS: Analysis of data from 640 patients (chronic CH: 287/640 [44.8%]; female: 264/640 [41.3%]; male: 373/640 [58.3%]; gender diverse: three of 640 [0.5%]; age range: 18-86 years; mean [standard deviation] Cluster Headache Scales subscale disability score: 36.9 [9.8]; out of 869 respondents) revealed that both attack frequency and fear of attacks significantly predicted pain-related disability (p < 0.001, percentage of variance explained: R2 = 0.24). More variance was explained by fear of attacks (R2 = 0.22) than by attack frequency (R2 = 0.02). This relationship remained significant even when controlling for depression and anxiety, which were also identified as independent predictors of pain-related disability (p < 0.001, R2 = 0.44). CONCLUSION: This study emphasizes the relevance of psychological factors in CH-related disability. Fear of attacks was found to be an independent predictor, while attack frequency was of minor relevance. Empirical investigation of the FAM in CH could improve the understanding of the mechanisms underlying disability and contribute to the development of CH-specific interventions.

Minocycline Abrogates Individual Differences in Nerve Injury-Evoked Affective Disturbances in Male Rats and Prevents Associated Supraspinal Neuroinflammation.

Chronic neuropathic pain precipitates a complex range of affective and behavioural disturbances that differ markedly between individuals. While the reasons for differences in pain-related disability are not well understood, supraspinal neuroimmune interactions are implicated. Minocycline has antidepressant effects in humans and attenuates affective disturbances in rodent models of pain, and acts by reducing neuroinflammation in both the spinal cord and brain. Previous studies, however, tend not to investigate how minocycline modulates individual affective responses to nerve injury, or rely on non-naturalistic behavioural paradigms that fail to capture the complexity of rodent behaviour. We investigated the development and resolution of pain-related affective disturbances in nerve-injured male rats by measuring multiple spontaneous ethological endpoints on a longitudinal naturalistic foraging paradigm, and the effect of chronic oral minocycline administration on these changes. Disrupted foraging behaviours appeared in 22% of nerve-injured rats - termed 'affected' rats - and were present at day 14 but partially resolved by day 21 post-injury. Minocycline completely prevented the emergence of an affected subgroup while only partly attenuating mechanical allodynia, dissociating the relationship between pain and affect. This was associated with a lasting downregulation of ΔFosB expression in ventral hippocampal neurons at day 21 post-injury. Markers of microglia-mediated neuroinflammation were not present by day 21, however proinflammatory microglial polarisation was apparent in the medial prefrontal cortex of affected rats and not in CCI minocycline rats. Individual differences in affective disturbances following nerve injury are therefore temporally related to altered microglial morphology and hippocampal neuronal activation, and are abrogated by minocycline.

Adverse childhood experience is associated with an increased risk of reporting chronic pain in adulthood: a stystematic review and meta-analysis.

Background: Adverse childhood experiences (ACEs) have been shown to negatively affect health in adulthood. Estimates of associations between ACEs and chronic painful conditions are lacking.Objectives: This systematic review and meta-analysis aimed to evaluate associations between exposure to ACEs and chronic pain and pain-related disability in adults.Methods: We searched 10 electronic databases from inception to February 2023. We included observational studies assessing associations between direct ACEs (childhood sexual, physical, emotional abuse, or neglect) alone or in combination with indirect ACEs (witnessing domestic violence, household mental illness), and adult chronic pain (≥3 months duration) and pain-related disability (daily activities limited by chronic pain). Pairs of reviewers independently extracted data and assessed study risks of bias. Random-effect models were used to calculate pooled adjusted odds ratios [aOR]. Tau square [T2], 95% prediction intervals [95%PI] and I2 expressed the amount of heterogeneity, and meta-regressions and subgroup meta-analyses investigated sources of heterogeneity (PROSPERO: CRD42020150230).Results: We identified 85 studies including 826,452 adults of which 57 studies were included in meta-analyses. Study quality was generally good or fair (n = 70). The odds of reporting chronic pain in adulthood were significantly higher among individuals exposed to a direct ACE (aOR, 1.45, 95%CI, 1.38-1.53). Individuals reporting childhood physical abuse were significantly more likely to report both chronic pain (aOR, 1.50, 95CI, 1.39-1.64) and pain-related disability (1.46, 95CI, 1.03-2.08) during adulthood. Exposure to any ACEs alone or combined with indirect ACEs significantly increase the odds of adult chronic painful conditions (aOR, 1.53, 95%CI, 1.42-1.65) and pain-related disability (aOR, 1.29; 95%CI, 1.01-1.66). The risk of chronic pain in adulthood significantly increased from one ACE (aOR, 1.29, 95%CI, 1.22-1.37) to four or more ACEs (1.95, 95%CI, 1.73-2.19).Conclusions: Single and cumulative ACEs are significantly associated with reporting of chronic pain and pain-related disability as an adult.

Previous meta-analyses highlighted the negative impact of adverse childhood experiences on physical, psychological, and behavioural health across the lifespan.We found exposure to any direct adverse childhood experience, i.e. childhood sexual, physical, emotional abuse, or neglect alone or combined, increased the risk of reporting chronic pain and pain-related disability in adulthood.The risk of reporting chronic painful disorders increased with increasing numbers of adverse childhood experiences.

Fear avoidance, fear of falling, and pain disability in hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorders.

PURPOSE: Hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD) are understudied conditions characterized by hallmark hypermobility and chronic pain. Disease manifestations lead to significant disability. Understanding predictors of disability, over and above the univariate construct of pain severity, is necessary to tailor treatment. Thus, the current study examined the impact of the Fear-Avoidance Model [FAM] on disability in hEDS/HSD. Fear of falling was included as a novel fear-avoidance factor impacting disability. METHODS: A total of 168 individuals with hEDS/HSD answered a cross-sectional online survey regarding FAM constructs, fear of falling, disability, and clinical-demographic factors. A hierarchical regression analysis was used to assess whether FAM constructs and fear of falling significantly predicted disability, over and above pain severity and age. RESULTS: Pain catastrophizing, anxiety, and fear of falling contributed significant unique predictive relations, above age and average pain severity. Pain severity and fear of falling were the strongest unique predictors of disability. CONCLUSIONS: This is the first study to assess the relations among FAM constructs, pain severity, and disability in hEDS/HSD, and introduces fear of falling as a novel fear-avoidance factor specific to this population. Future research should apply these findings towards individualized interventions to improve disability in hEDS/HSD.

Disability is significant in hypermobile Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorders, and may be predicted by psychosocial factors of anxiety, pain catastrophizing, and fear of falling.Our findings suggest that improving disability in hypermobile Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorders involves the consideration of physical factors, such as pain severity, along with psychosocial factors, the latter of which are amenable to change through individualized intervention plans.Fear of falling is a novel fear-avoidance construct that should be considered in future research and clinical settings to increase functionality in this frequently falling population.

Pain-Related Cognitive Processes, Pain Interference, and Alexithymia in Patients With Primary Headaches.

Objectives This study aims to investigate the effects of pain-related cognitive processes (PRCPs) and emotional state on pain-related disability (PRD) and pain interference (difficulty in performing daily routines, difficulty in engaging in social activities [the enjoyment of life], and the impact on work and/or school performance) in patients with primary headaches (PHs). Methodology PRCPs were evaluated with the Pain Anxiety Symptom Scale-20 (PASS-20), Pain Catastrophizing Scale (PCS), and Pain Belief Questionnaire (PBQ). Anxiety, depression, and alexithymia were investigated to assess the emotional state. PRD was assessed by Headache Impact Test-6 (HIT-6). Health-related quality of life (HRQoL) was evaluated under three headings: daily activities (with Short Form-36 [SF-36] Question [Q] 22), social activities (with Graded Chronic Pain Scale-Revised [GCPS-R] Q 4), as well as the working ability (with GCPS-R Q 5). Two separate models were constructed to identify the factors influencing PRD and HRQoL in PHP: M1 to reveal the factors affecting PRD and M2 to determine the independent factors affecting pain interference. In both models, correlation analysis was applied first and the significant data were then evaluated with regression analysis. Results A total of 364 participants (74 healthy controls [HCs] and 290 PHPs) completed the study. In M1, the following domains were significantly associated with PRD: cognitive anxiety (ß = 0.098; 95% confidence interval [CI] = 0.001-0.405; P = 0.049); helplessness (ß = 0.107; 95% CI = 0.018-0.356; P = 0.031); alexithymia (ß = 0.077; 95% CI = 0.005-0.116; P = 0.033); depression (ß = 0.083; 95% CI = 0.014-0.011; P = 0.025). In M2, factors associated with impairment in daily activities for PHP were as follows: duration of pain, pain intensity, alexithymia, escape-avoidance response, psychological anxiety, anxiety, and poor sleep quality (R = 0.770; R2 = 0.588). The independent factors affecting social activities for PHP were pain intensity and pain-related anxiety (R = 0.90; R2 = 0.81). Independent risk factors that affected the ability to work for PHP were pain intensity, cognitive anxiety, escape-avoidance response, and pain anxiety (R = 0.90; R2 = 0.81). Conclusions This study highlights the importance of cognitive and emotional processes that help increase our understanding of the patient with PHs. This understanding may help to reduce disability and improve the quality of life in this population by helping to guide multidisciplinary treatment goals.

The role of co-occurring insomnia and mental distress in the association between lumbar disc degeneration and low back pain related disability.

BACKGROUND: Lumbar disc degeneration (LDD) is associated with low back pain (LBP). Although both insomnia and mental distress appear to influence the pain experience, their role in the association between LDD and LBP is uncertain. Our objective was to investigate the role of co-occurring insomnia and mental distress in the association between LDD and LBP-related disability. METHODS: A total of 1080 individuals who had experienced LBP during the previous year underwent 1.5-T lumbar magnetic resonance imaging, responded to questionnaires, and participated in a clinical examination at the age of 47. Full data was available for 843 individuals. The presence of LBP and LBP-related disability (numerical rating scale, range 0-10) were assessed using a questionnaire. LDD was assessed by a Pfirrmann-based sum score (range 0-15, higher values indicating higher LDD). The role of insomnia (according to the five-item Athens Insomnia Scale) and mental distress (according to the Hopkins Symptom Check List-25) in the association between the LDD sum score and LBP-related disability was analyzed using linear regression with adjustments for sex, smoking, body mass index, education, leisure-time physical activity, occupational physical exposure, Modic changes, and disc herniations. RESULTS: A positive association between LDD and LBP-related disability was observed among those with absence of both mental distress and insomnia (adjusted B = 0.132, 95% CI = 0.028-0.236, p = 0.013), and among those with either isolated mental distress (B = 0.345 CI = 0.039-0.650, p = 0.028) or isolated insomnia (B = 0.207, CI = 0.040-0.373, p = 0.015). However, among individuals with co-occurring insomnia and mental distress, the association was not significant (B = -0.093, CI = -0.346-0.161, p = 0.470). CONCLUSIONS: LDD does not associate with LBP-related disability when insomnia and mental distress co-occur. This finding may be useful when planning treatment and rehabilitation that aim to reduce disability among individuals with LDD and LBP. Future prospective research is warranted.

The role of pain-related disability on treatment outcome and psychosocial symptoms in patients with temporomandibular disorders - a pilot study.

OBJECTIVE: The aim of the pilot study was to investigate the association of pain-related disability with the outcome of conservative treatment of temporomandibular disorders (TMD) and with depressive and non-specific physical symptoms among TMD pain patients utilizing Graded Chronic Pain Scale 1.0 (GCPS1.0) as a screening instrument. MATERIAL AND METHODS: The study included 80 adult patients who were referred to the Oral and Maxillofacial Department, Oulu University Hospital, Finland, due to TMD pain. At baseline, pain-related disability was assessed by using the GCPS1.0 according to the Research Diagnostic Criteria for TMD (RDC/TMD), and the patients were categorized into three TMD subtypes, 1-3. Patients were given conservative TMD treatment. At follow-up visits (1, 3, 6, and 12 months), patients evaluated the pain intensity on an NRS and described the treatment outcome and the severity of the TMD symptoms on a numerical scale. RESULTS AND CONCLUSIONS: Patients with TMD subtype 3 (moderate/severe disability) had the highest NRS scores and described their symptoms as most severe at each time point, statistically significantly so at 1-month and 6-month follow-up (p < .05). The highest proportion of depressive symptoms was found in TMD subtype 3 (p < .05). The current pilot study showed that moderate/severe TMD-related disability, based on the GCPS 1.0 as a screening tool, may be linked with poor treatment outcome and depressive symptoms. Studies with larger samples are needed to confirm the results.

The Dutch language version of the Pain Disability Index (PDI-DLV): psychometric properties in breast cancer patients.

BACKGROUND: Pain after breast cancer surgery is a common and disabling problem. A reliable and valid questionnaire to assess pain-related disability is the Pain Disability Index (0-70). However, properties of the Dutch version (PDI-DLV) have never been investigated in this population. OBJECTIVE: To assess psychometric properties of the PDI-DLV after breast cancer surgery. METHODS: For reliability, relative and absolute reliability were calculated with a one-week test-retest interval, as well as internal consistency. Moreover, content and construct validity were examined to evaluate validity. RESULTS: One hundred twenty-three women were included. Relative reliability was good (intraclass correlation coefficient = 0.80). Standard error of measurement and minimal detectable change (absolute reliability) were 5.57 and 15.45 points, respectively. The mean difference between two measurements was -1.98 points, with 95% limits of agreement equal to 13.19 and -17.15. The within-subjects coefficient of variation was 59%. Internal consistency was confirmed (α = 0.87). The PDI-DLV was scored as understandable and complete (content validity). Construct validity was supported by confirmation of more than 75% of the tested hypotheses and of the one-factor model. CONCLUSION: The PDI-DLV is a valid questionnaire to assess pain-related disability 1 year after breast cancer surgery. Although absolute reliability is disputable, its good relative reliability allows evaluating changes between subjects.

[Treatment expectations of multimodal pain therapy inpatients]. / Behandlungserwartungen bei Patienten einer stationären multimodalen Schmerztherapie.

BACKGROUND: Apart from rehabilitation research, there have been no studies regarding the expectations of patients with chronic back pain in terms of inpatient multimodal pain therapy. The aim of this naturalistic longitudinal study is to explore treatment expectations, their fulfilment, and influence on the treatment success of inpatient multimodal pain therapy. METHODS: This study included 118 patients with chronic back pain who were physically examined and assessed for their psychological comorbidity. They were interviewed pre and post pain therapy. Treatment expectations were recorded via the questionnaire for assessing rehabilitational expectations and motivations (FREM-17), and further variables via the Pain Disability Index (PDI, german version) and the german Hospital Anxiety and Depression Scale (HADS-D). RESULTS: The results show that treatment expectations have an impact on therapy success or failure. In particular, patients' expectations of coping with illness and recovery could be met by inpatient multimodal pain therapy, whereas health and pension-related expectations remained unfulfilled. In addition to the treatment expectations, the therapy result was primarily determined by the patient's ability to perform before the therapy. CONCLUSIONS: From the clinical side, treatment expectations should be explored and checked for feasibility to avoid patient disappointment.

[Chronic pain in elderly people during the COVID-19 pandemic]. / Chronische Schmerzen im Seniorenalter vor dem Hintergrund der COVID-19-Pandemie.

BACKGROUND: International studies have shown negative effects of the COVID-19 pandemic on mood and levels of distress. Correlations between the pandemic and higher levels of pain as well as greater pain-related disability have also been found; however, studies report ambiguous results about whether elderly people cope differently with the pandemic and its effects. METHODS: The University Hospital of Würzburg offers multimodal pain therapy for older adults. The current study performed a retrospective analysis of routine data measured during an interdisciplinary multimodal assessment. We compared n = 75 patients taking part in the therapy during 2018 and 2019 to n = 42 patients assessed in 2020-2021. We measured pain, mental distress and physical functioning using the German Pain Questionnaire, clinical diagnosis, and geriatric tests of physical fitness. RESULTS: Both subgroups did not differ in demographic characteristics, neither did we find significant differences regarding pain intensity, pain-related disability, and mental health; however, patients before the pandemic reported a higher number of days on which they felt limited due to pain. In the physical performance test, we even found significantly better results during the COVID-19 pandemic. DISCUSSION: The current data do not support an aggravation of pain or mental and physical well-being. Possible explanations could be better resilience in elderly people due to their experience of life, financial security or less change in their daily life.

Pain acceptance and illness intrusiveness in low-back pain: A longitudinal study.

Background: In chronic pain syndromes, acceptance of pain may be a better approach than pain control. So far, little data have been available on how pain and its acceptance affect illness intrusiveness among patients with low-back pain (LBP). Objective: The present longitudinal study evaluates the impact of pain acceptance on illness intrusiveness in patients with LBP. Methods: Study participants were asked to complete the following questionnaires during their visit (T1) at one of four diverse rheumatologic outpatient clinics, and then 2-3 months later (T2) via phone or online: Chronic Pain Acceptance Questionnaire (CPAQ), Illness Intrusiveness Rating Scale (IIRS), Roland-Morris Disability Questionnaire (RMDQ), Patient Health Questionnaire Depression subscale (PHQ9), and socioeconomic data. Results: One hundred and twenty-seven individuals completed the questionnaires at baseline (31 having acute, 15 subacute and 81 chronic low back pain) and 97 at follow-up. Illness intrusiveness was negatively correlated with chronic pain acceptance both at T1 (r = -0.39) and T2 (r = -0.44). Illness intrusiveness scores have not changed significantly from T1 (M = 28.59 SD = 13.08) to T2 (M = 28.24, SD = 15.76). In a multiple regression model-including pain intensity, functional status, pain acceptance, depression severity, age, sex and educational level-the independent predictors of follow-up illness intrusiveness scores were lower pain acceptance and higher depression scores. Conclusions: In our study, patients with acute, subacute and chronic low back pain reported similar levels of illness intrusiveness. In addition, illness intrusiveness scores have not changed significantly during the 2-month follow-up period and pain acceptance proved to be a significant independent predictor of illness intrusiveness among patients with chronic low-back pain.

Psychosocial profiles and their correlation with physical diagnosis in temporomandibular disorders, a preliminary report.

OBJECTIVE: To assess representative psychosocial features in a group of temporomandibular disorder (TMD) patients from Jordan using Axis II of the Diagnostic Criteria for TMD (DC/TMD) protocol. METHODS: Ninety-eight TMD patients were examined according to Axis I DC/TMD protocol in addition to assessment of their pain-related disability, psychological distress, and stress reactivity. RESULTS: Just under half of the patients (49%) had high intensity of characteristic pain (self-reported TMJ-related pain) and one-third (32%) had high levels of pain-related disability. Furthermore, significant proportions of patients expressed moderate-severe degrees of distress and stress reactivity (41% and 39%, respectively). Significant correlations were identified between the Graded Chronic Pain Scale (GCPS) and each of the pain-related TMD subgroups. CONCLUSION: TMD patients are susceptible to high levels of pain-related psychosocial impairment, and clinicians should be aware of the possible correlations between the physical TMD diagnosis and specific psychosocial features during treatment planning.

Mindfulness Facets Associated with Orofacial Pain Outcomes.

Mindfulness can help improve chronic pain outcomes. This cross-sectional study is the first to test associations between specific mindfulness facets and pain-related outcomes (pain intensity, pain-related disability, anxiety, and depression) in individuals with chronic orofacial pain (N = 303). "Nonjudging" was associated with positive pain-related outcomes. "Observing" was associated with worse pain-related disability and anxiety outcomes. Multiple regressions revealed that "nonjudging" was the only facet independently associated with pain-related disability, anxiety, and depression beyond the other facets and clinical/demographic variables. Cultivating a nonjudgmental stance may facilitate positive orofacial pain outcomes.

Association Between Coping Strategies and Pain-Related Outcomes Among Individuals with Chronic Orofacial Pain.

BACKGROUND: Chronic orofacial pain is associated with substantial pain-related disability and emotional distress. Understanding the relationship between individuals' coping strategies and pain-related outcomes is important yet understudied in this population. PURPOSE: To test the cross-sectional association of three coping strategies (pain catastrophizing, kinesiophobia and mindfulness) to four pain-related outcomes (depression, anxiety, pain intensity, and pain-related disability) among individuals with chronic orofacial pain, after accounting for relevant demographic and clinical variables. METHODS: Individuals (N=303) with heterogeneous chronic orofacial pain (eg, trigeminal neuralgia, other trigeminal neuropathic pain, persistent idiopathic facial pain and other types) completed self-report measures of coping (Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia, and the 15-item Five Facet Mindfulness Questionnaire), pain intensity and pain-related disability (Graded Chronic Pain Scale), and PROMIS measure of anxiety and depression. We conducted 4 two-step hierarchical regressions for each of the four pain-related and emotional outcomes, with the first step including demographic and clinical covariates, and the second step including the three coping variables together. RESULTS: Pain catastrophizing was the only coping variable significantly associated with pain intensity (B=0.362, SE=0.115, p=0.002, 3% variance explained) and pain-related disability (B =0.813, SE=0.162, p<0.001, 7% variance explained). Pain catastrophizing (B=0.231-0.267, SE=0.046-0.051-0.050, p<0.001), kinesiophobia (B=0.201-0.316, SE=0.081-0.084, p<0.001-0.018), and mindfulness (B=0.231-0.306, SE=0.046-0.067, p<0.001) were each independently associated with symptoms of anxiety and depression, with the largest incremental variance added by catastrophizing (5-8%) and mindfulness (5%). CONCLUSION: Pain catastrophizing appears to be an important intervention target to improve pain intensity, pain-related disability, anxiety and depression among individuals with chronic orofacial pain. Kinesiophobia and mindfulness may be additional treatment targets for interventions to improve anxiety and depression.

Pain-related disability, PTSD symptoms, and mood among a comorbid chronic pain and PTSD sample prior to and during the COVID-19 pandemic.

There is a knowledge gap when treating comorbid chronic pain and posttraumatic stress disorder (PTSD) during the COVID-19 pandemic. Addressing this gap, 169 individuals (57.4% female), aged 39.8 years were recruited based on levels of pain-related disability and PTSD symptoms. Participants were assessed prior to, and during, the COVID-19 pandemic. Improvements in pain-related disability were marginally attenuated for the comorbid group, compared to the chronic pain group. Results show that some condition-specific symptoms may not have been affected by the COVID-19 pandemic. Cautious interpretation is warranted due to only two time points and the lack of a diverse sample.

The role of identity in chronic pain cognitions and pain-related disability within a clinical chronic pain population.

OBJECTIVE: Chronic pain has a significant impact on functioning and results in the disruption of one's assumed life trajectory, potentially altering their self-perceived identity. The present research is designed to determine whether identity-related issues are associated with common chronic pain cognitions and pain-related disability, which may help inform understanding of clinical chronic pain populations. METHOD: Ninety-eight adult chronic pain patients were assessed at a local pain clinic during a regularly scheduled appointment focusing on pain management. Multivariate hierarchal regression was used to determine whether issues related to identity and death anxiety were associated with pain catastrophizing, pain acceptance, and pain-related disability, above and beyond pain severity, fear-avoidance, and age. RESULTS: Self-concept clarity was significantly related to pain catastrophizing and pain acceptance, above and beyond death anxiety, pain severity, fear-avoidance, and age. Death anxiety was associated with pain catastrophizing, pain acceptance, and pain-related disability above and beyond pain severity, fear-avoidance, and age. CONCLUSIONS: To the best of our knowledge, the present study is the first examination of self-concept clarity and death anxiety as they relate to pain catastrophizing, pain acceptance, and pain-related disability. These descriptive results support the inclusion of identity and death anxiety within the pain experience and could serve as a foundation for future directions relevant to clinical applications.

Authenticity as a Resilience Factor Against CV-19 Threat Among Those With Chronic Pain and Posttraumatic Stress Disorder.

OBJECTIVE: The novel coronavirus (2019; CV-19) is linked to increases in emotional distress and may be particularly problematic for those with pre-existing mental and physical conditions, such as chronic pain and posttraumatic stress disorder (PTSD). However, little empirical research has been published on resilience factors in these individuals. The present study aims to examine authenticity as a resilience factor among those with chronic pain and/or PTSD. METHODS: Prior to the national response to the pandemic (January 10-24, 2020), participants were screened for pain-related disability (Oswestry Disability Index; ODI) and PTSD symptoms (Posttraumatic Checklist for DSM-5; PCL-5), and on the basis of those responses were categorized into one of four groups: healthy, chronic pain only, PTSD only, or comorbid chronic pain and PTSD. During the CV-19 pandemic (May 5-May 13, 2020), participants responded again to the ODI and PCL-5, in addition to the Wood Authenticity Scale, Brief Pain Inventory, and items related to the CV-19 pandemic. RESULTS: A total of 110 participants (54.55% women), aged 42.19 (SD = 13.16), completed the survey during the pandemic. The comorbid group endorsed higher levels of CV-19 Threat and Impact compared to all other groups. Authenticity moderated this relationship relevant to CV-19 Threat among those in the chronic pain only group, and not in any other group. CONCLUSION: The comorbid group endorsed higher levels of CV-19 Threat and Impact compared to all other groups. Importantly, greater authenticity was associated with less CV-19 Threat in the chronic pain only group, and not in any other group. The present study also highlights the importance of engaging authentically for those with chronic pain during the pandemic.

Youth and parent perceptions on participating in specialized multidisciplinary pain rehabilitation options: A qualitative timeline effect analysis.

Background: Little is known about how the specialized treatment journey is perceived by youth with pain-related disability and their parents. Aims: Describe and compare the treatment effects and outcomes as perceived by youth and their parents enrolled in intensive interdisciplinary pain treatment (IIPT) or multimodal treatment (MMT). Methods: Eleven IIPT youth and five parents and three MMT youth and five parents were recruited. All were asked to complete a treatment journey timeline, followed by separately conducted semistructured interviews. Transcribed interviews were analyzed using reflective thematic analysis. Results: The main themes spanned the treatment trajectory. All participants described similar initial struggles (Theme 1). Positive and negative treatment effects associated with acquisitions and disruptions (Theme 2), and outcomes post-discharge related to supports and realities (Theme 3) emerged. Knowledge, skills, and support acquisition during treatment and feeling empowered and confident to self-manage postdischarge were identified as IIPT benefits. However, the change effort and life disruptions required and the difficulty transitioning to real life postprogram were acknowledged as detrimental IIPT impacts. Continuing with life as usual and maintaining supports in daily contexts (e.g., school personnel, friends) were reported MMT benefits. However, the challenges of managing pain, treatment adherence within the competing demands of daily realities, and the lack of support to integrate strategies were emphasized as detrimental MMT impacts. Conclusions: Detailed impacts of two specialized multidisciplinary pain rehabilitation interventions on the lives of youth with pain-related disability and their parents are described. The treatments benefits and previously unexplored detrimental effects are unveiled.

Contexte: On en sait peu sur les parcours de traitement spécialisés tels que perçus par les jeunes ayant une incapacité liée à la douleur et par leurs parents.Objectifs: Décrire et comparer les effets et les résultats du traitement tels qu'ils sont perçus par les jeunes inscrits à un traitement interdisciplinaire intensif de la douleur ou à un traitement multimodal, ainsi que par leurs parents.Méthodes: Onze jeunes inscrits à un traitement interdisciplinaire intensif de la douleur et cinq parents, ainsi que trois jeunes inscrits à un traitement multimodal et cinq parents, ont été recrutés. Tous ont été invités à décrire le calendrier de leur parcours de traitement, puis à participer à des entrevues semi-structurées menées séparément. Les entrevues transcrites ont été analysées à l'aide d'une analyse thématique réflexive.Résultats: Les principaux thèmes couvraient la trajectoire du traitement. Tous les participants ont décrit des difficultés initiales similaires (Thème 1). L'association des effets positifs et négatifs du traitement avec les acquis et les perturbations (Thème 2), et les issues liées au soutien et aux réalités suite à leur congé (Thème 3) ont émergé. L'acquisition de connaissances et d'habiletés, l'accès à du soutien et le sentiment d'autonomisation et de confiance en sa capacité d'autoprise en charge après le congé ont été répertoriés comme des avantages du traitement interdisciplinaire intensif de la douleur. Toutefois, les efforts de changement requis et les perturbations de la vie nécessaires, ainsi que les difficultés de la vie réelle après le programme, ont été considérés comme des répercussions négatives du traitement interdisciplinaire intensif de la douleur. La possibilité de poursuivre la vie comme d'habitude et de conserver le soutien dans des contextes de la vie quotidienne (ex. : personnel scolaire, amis) ont été rapportés comme des avantages du traitement multimodal. Toutefois, les défis liés à la prise en charge de la douleur, l'adhésion au traitement dans le cadre des exigences concurrentes des réalités quotidiennes, ainsi que le manque de soutien pour intégrer les stratégies, ont été mis en relief comme des effets néfastes du traitement multimodal.Conclusions: Les effets détaillés de deux interventions multidisciplinaires spécialisées en matière de réadaptation pour la douleur dans la vie de jeunes atteints d'une incapacité liée à la douleur et de leurs parents ont été décrits. Les avantages des traitements et leurs effets néfastes qui n'avaient pas encore été étudiés ont été dévoilés.

Evaluation of the Arabic version of the Chronic Pain Grade scale: Psychometric properties.

To increase our understanding of chronic pain in clinical and research contexts, an assessment of its dimensions using reliable and valid self-reported pain measures is imperative. However, well-validated Arabic chronic pain assessment scales are lacking. The Chronic Pain Grade (CPG) scale has been used worldwide, yet an Arabic version of the CPG scale has not yet been validated. Thus, we conducted this study to demonstrate the psychometric properties, including reliability, convergent validity, and construct validity of the Arabic CPG scale. A cross-sectional study was conducted in two hospitals in Saudi Arabia. Data were collected from a convenience sample of 233 chronic pain patients. The confirmatory factor analysis showed an excellent fit with the factor structure of the CPG scale and, thus, supported construct validity. The two identified subscales were pain intensity and pain disability. Convergent validity was supported by having significant correlations between the short-form McGill Pain Questionnaire and CPG subscales. Internal consistency reliability was demonstrated, as Cronbach's α was 0.916 for pain intensity and 0.815 for pain disability. This study provides evidence that the Arabic CPG scale is a reliable and valid measure of chronic pain dimensions, including pain intensity, and pain-related disability. This Arabic version of the CPG scale has the potential to expand research and clinical assessment in the Arab world. Future studies are required for further validation.

Exploring the underlying mechanism of pain-related disability in hypermobile adolescents with chronic musculoskeletal pain.

OBJECTIVES: A significant proportion of adolescents with chronic musculoskeletal pain (CMP) experience difficulties in physical functioning, mood and social functioning, contributing to diminished quality of life. Generalized joint hypermobility (GJH) is a risk factor for developing CMP with a striking 35-48% of patients with CMP reporting GJH. In case GJH occurs with one or more musculoskeletal manifestations such as chronic pain, trauma, disturbed proprioception and joint instability, it is referred to as generalized hypermobility spectrum disorder (G-HSD). Similar characteristics have been reported in children and adolescents with the hypermobile Ehlers-Danlos Syndrome (hEDS). In the management of CMP, a biopsychosocial approach is recommended as several studies have confirmed the impact of psychosocial factors in the development and maintenance of CMP. The fear-avoidance model (FAM) is a cognitive-behavioural framework that describes the role of pain-related fear as a determinant of CMP-related disability. CONTENT: Pubmed was used to identify existing relevant literature focussing on chronic musculoskeletal pain, generalized joint hypermobility, pain-related fear and disability. Relevant articles were cross-referenced to identify articles possibly missed during the primary screening. In this paper the current state of scientific evidence is presented for each individual component of the FAM in hypermobile adolescents with and without CMP. Based on this overview, the FAM is proposed explaining a possible underlying mechanism in the relations between GJH, pain-related fear and disability. SUMMARY AND OUTLOOK: It is assumed that GJH seems to make you more vulnerable for injury and experiencing more frequent musculoskeletal pain. But in addition, a vulnerability for heightened pain-related fear is proposed as an underlying mechanism explaining the relationship between GJH and disability. Further scientific confirmation of this applied FAM is warranted to further unravel the underlying mechanism.In explaining disability in individuals with G-HSD/hEDS, it is important to focus on both the physical components related to joint hypermobility, in tandem with the psychological components such as pain-related fear, catastrophizing thoughts and generalized anxiety.
