Levels Of Pain Catastrophizing Research Articles

Systematic Review: Psychosocial Correlates of Pain in Pediatric Inflammatory Bowel Disease.

Pain is a common symptom in pediatric inflammatory bowel disease (IBD) and is associated with poor health outcomes, yet additional knowledge about the psychosocial correlates of pain is needed to optimize clinical care. The purpose of this study is to systematically review the psychosocial factors associated with pain and pain impact in youth diagnosed with IBD within a developmentally informed framework. Manual and electronic searches yielded 2641 references. Two authors conducted screening (98% agreement), and data extraction was performed in duplicate. Average study quality was rated using the National Institutes of Health Quality Assessment Tool. Ten studies (N = 763 patients; N = 563 Crohn disease, N = 200 ulcerative/ indeterminate colitis) met the inclusion criteria. Findings showed consistent evidence that higher levels of child depression symptoms and child pain catastrophizing were associated with significantly greater pain and pain impact (magnitude of association ranged from small to large across studies). Greater pain and pain impact were also associated with higher levels of child anxiety symptoms, child pain threat, child pain worry, and parent pain catastrophizing. Within the included studies, female sex and disease severity were both significantly associated with pain and pain impact. Study quality was moderate on average. There is evidence that child psychosocial factors are associated with pain and pain impact in pediatric IBD; more studies are needed to examine parent- and family-level psychosocial factors. Youth with IBD should be routinely screened for pain severity, pain impact, and psychosocial risk factors such as anxiety/depression.

Treatment preferences in fibromyalgia patients: A cross-sectional web-based survey.

Therapeutic approaches to fibromyalgia (FM) are shifting towards a combined multi-treatment approach to tackle the variety of symptoms experienced in FM. Importantly, little is known about FM patients' attitude towards the available treatments. A cross-sectional web survey obtained responses from 464 individuals who satisfied diagnostic criteria for FM. Respondents were asked to report which treatments they adopted in their past, present and intend to adopt in the future. They also rated their level of well-being, depression, anxiety and pain catastrophizing. Data revealed a predominantly combined multi-treatment approach in a sample characterized by middle-aged, Caucasian women. Respondents reported pervasive use of pharmacological therapy but had also adopted non-pharmacological treatment in the past. Future intentions clustered on alternative treatment or no treatment. Regression analyses revealed that pharmacological treatment in the past was predictive of both pharmacological and non-pharmacological treatments in the present. However, use of non-pharmacological treatment in the past was uniquely predictive of its reuse in the present and future. This pattern was also accounted for by individual differences in pain magnification and well-being in the past. Treatment preferences of FM individuals reveal an ambivalent combination of heavy reliance on pharmacological treatment with lower but consistent reliance on non-pharmacological treatment for those individuals who used it in the past and present. This finding may inform longitudinal research into the relationship between pharmacological and non-pharmacological treatment preference in FM patients, which could in turn inform guidelines for individualized therapeutic plans for clinicians. Individuals with fibromyalgia reported the use of non-pharmacological and pharmacological treatments in the past but a predominant use of a pharmacological approach overall. Patterns of treatment experienced in the past were differentially related to future preferences. Pharmacological treatment in the past was likely to lead to both pharmacological and non-pharmacological choices in the present. However, non-pharmacological treatment in the past was more likely to be chosen again in the present and future, but unlikely to lead to a pharmacological choice.

Sensory processing patterns affect headache severity among adolescents with migraine

ObjectiveTo evaluate the relationship between pain catastrophizing level, sensory processing patterns, and headache severity among adolescents with episodic migraine.BackgroundCatastrophizing about pain is a critical variable in how we understand adjustment to pain and has a unique contribution in predicting pain intensity. Recent reports found that migraine is also related to enhanced sensory sensitivity. However, the relationship between pain severity, pain catastrophizing level and sensory sensitivity requires greater study especially among adolescents.MethodsParticipants were 92 adolescents aged 13–18 years, 40 with episodic migraine and 52 healthy controls. The migraine patients were prospectively recruited from outpatient pediatric neurology clinics. All participants completed the Adolescent/Adult Sensory Profile (AASP), and the Pain Catastrophizing Scale for children (PCS-ch). The migraine groups also completed the PedMIDAS, which measures Headache related disability.ResultsAdolescents with migraine had significantly lower tendency to seek sensory input than healthy controls. Elevated rumination and helplessness correlated with higher migraine pain severity. Tendency to avoid sensory input predicted the migraine related disability level. They also significantly higher pain catastrophizing level than healthy controls, as seen in enhanced rumination (p ≤ 0.001) and helplessness (p ≤ 0.05).ConclusionsSensory processing difficulties are common among adolescents with episodic migraine. Sensory avoidance may be related to pain experience, and pain catastrophizing and disability level.

Prevalence of Posttraumatic Stress Symptoms and Associated Characteristics Among Patients With Chronic Pain Conditions in a Norwegian University Hospital Outpatient Pain Clinic.

IntroductionComorbid posttraumatic stress disorder (PTSD) in patients with chronic pain may have a negative effect on the course and outcome of both disorders. Nevertheless, the co-occurrence of the two conditions is often overlooked in clinical settings. Further, little is known about how PTSD is associated with biopsychosocial characteristics in this patient group. The first objective was to assess the prevalence of posttraumatic stress symptoms (PTSS) in patients with chronic pain in a Norwegian university hospital outpatient pain clinic. The second objective was to investigate possible associations between PTSS and adverse outcomes such as pain intensity, disability, and distress. The third objective was to compare the PTSS prevalence rates between primary versus secondary pain conditions.Materials and methodsSix hundred and ninety-two patients meeting for pain assessment completed self-report questionnaires about PTSS and possibly associated factors. The Life Events Checklist and the Stressful Life Events Screening Questionnaire were used to screen for potentially traumatic life events. The Impact of Events Scale – Revised and the PTSD Checklist for DSM-5 were used to assess PTSS. Differences between patients with and without severe PTSS on the possibly associated variables were analyzed by chi-squared-, and t-tests.Results20.7% of the participants reported a level of PTSS qualifying for a PTSD diagnosis. These patients reported higher levels of pain intensity, pain bothersomeness, disability, and psychological distress, as well as lower levels of self-efficacy. They also reported higher levels of pain catastrophizing, perceived injustice, fatigue, and sleep difficulties. Finally, there was not a significant difference in prevalence rates between primary and secondary pain conditions.DiscussionPTSS are frequent in patients with chronic pain, and a range of psychological characteristics is associated with a high level of such symptoms in this patient group. Patients with both conditions report a significantly higher symptom load, and the potential impact on the individual’s life is major. In terms of pain condition, there were no differences in PTSS between primary pain conditions and secondary pain conditions in this pain population. This study emphasizes the importance of increased attention on PTSS when seeing patients with chronic pain conditions in clinical practice.

Everyday Discrimination in Adults with Knee Pain: The Role of Perceived Stress and Pain Catastrophizing.

PurposeResearch indicates pain-related disparities in the impact of knee osteoarthritis (OA) across both sex and ethnicity/race. While several factors likely contribute to these disparities, experiences of discrimination are associated with poor OA-related pain, disability, and functional performance. However, the mechanisms that mediate experiences of discrimination and OA-related outcomes are unclear. The current cross-sectional study examined the associations between everyday experiences of discrimination and clinical pain, disability and functional performance among non-Hispanic Black (NHB) and non-Hispanic White (NHW) persons with or at risk of knee OA and assessed the serial mediated model of perceived stress and pain catastrophizing on these relationships in women only.Patients and MethodsParticipants were 188 community-dwelling adults who presented with unilateral or bilateral knee pain and screened positive for clinical knee pain. Participants completed several measures including experiences of discrimination, Perceived Stress Scale, Coping Strategies Questionnaire-Revised (CSQ-R): Pain Catastrophizing subscale, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Graded Chronic Pain Scale (GCPS), and Short Physical Performance Battery (SPPB).ResultsAs compared to NHW participants, NHB individuals reported experiencing significantly higher levels of discrimination (F(1, 175)=26.660, p<0.001), greater levels of pain catastrophizing (F(1, 180)=12.919, p<0.001), higher levels of clinical pain and disability, and lower levels of physical function (ps<0.05). However, perceived stress was positively correlated with discrimination in the NHW group only (NHW females: r=0.40, p<0.01; NHW males: r=0.37, p<0.05). Further, perceived stress and pain catastrophizing mediated the relationship between discrimination and outcome variables (WOMAC pain, GCPS interference [pain disability], and SPPB function) in female participants after controlling for relevant sociodemographic variables (study site, age, race, income, and body mass index).ConclusionThese results may have implications for the treatment of perceived stress and catastrophizing as a means to reduce the negative impact of experiences of discrimination on the experience of chronic pain, particularly for women.

Exposure to Potentially Traumatic Events, Posttraumatic Stress Symptoms, Pain Catastrophizing, and Functional Somatic Symptoms Among Individuals With Varied Somatic Symptoms: A Moderated Mediation Model

The relationships between exposure to potentially traumatic events (PTEs), as well as posttraumatic stress symptoms (PTSS) and somatic syndromes, have recently been exemplified. Exposure to PTEs can also set in motion complex psychological processes such as pain catastrophizing that is associated with PTSS and somatic syndromes. However, the specific moderating role of pain catastrophizing in these links remains relatively unexamined. The present study aims to assess a moderated mediation model in which catastrophizing will moderate the indirect effect of exposure to PTEs on the number of somatic symptoms and chronic pain severity via PTSS, among individuals with somatic syndromes. A volunteers' sample of 175 Israeli adults with varied somatic symptoms responded to online validated self-report questionnaires in a cross-sectional designed study. Participants' self-reported PTSS rates (57.1%) were high. PTSS and pain catastrophizing, but not exposure to PTEs, were related to chronic pain severity. Interestingly, a moderated mediation analysis indicated that the indirect effect of catastrophizing in the relation between exposure to PTEs and the number of somatic symptoms via PTSS existed only among those with high levels of catastrophizing. The present study highlights the assumption that functional somatic syndromes (FSS) have much in common. Our findings support a moderated mediation model that begins with exposure to PTEs that leads to PTSS, which in turn increase the number of somatic symptoms. Higher levels of pain catastrophizing might attenuate this indirect link by affecting the interpretation of PTSS and create a vulnerability to more somatic symptoms. Thus, changes in cognitive-sensory processing in the form of catastrophic thinking can affect psychobiological processes and heighten sensitivity to stimuli arising in the body and should be considered as possible target for future research and psychological interventions.

The influence of nociceptive and neuropathic pain states on the processing of acute electrical nociceptive stimulation: A dynamic causal modeling study

IntroductionDespite the worldwide increase in prevalence of chronic pain and the subsequent scientific interest, researchers studying the brain and brain mechanisms in pain patients have not yet clearly identified the exact underlying mechanisms. Quantifying the neuronal interactions in electrophysiological data could help us gain insight into the complexity of chronic pain. Therefore, the aim of this study is to examine how different underlying pain states affect the processing of nociceptive information. MethodsTwenty healthy participants, 20 patients with non-neuropathic low back-related leg pain and 20 patients with neuropathic failed back surgery syndrome received nociceptive electrical stimulation at the right sural nerve with simultaneous electroencephalographic recordings. Dynamic Causal Modeling (DCM) was used to infer hidden neuronal states within a Bayesian framework. ResultsPain intensity ratings and stimulus intensity of the nociceptive stimuli did not differ between groups. Compared to healthy participants, both patient groups had the same winning DCM model, with an additional forward and backward connection between the somatosensory cortex and right dorsolateral prefrontal cortex. DiscussionThe additional neuronal connection with the prefrontal cortex as seen in both pain patient groups could be a reflection of the higher attention towards pain in pain patients and might be explained by the higher levels of pain catastrophizing in these patients. ConclusionIn contrast to the similar pain intensity ratings of an acute nociceptive electrical stimulus between pain patients and healthy participants, the brain is processing these stimuli in a different way.

Parental Psychological Factors and Quality of Life of Children With Inflammatory Bowel Disease

Parents have a central role in the management of children with inflammatory bowel disease (IBD). Alterations in parental psychological well-being may affect the patient's health-related quality of life (HRQoL). This study aimed to evaluate the correlation between maternal and paternal distress, anxiety, depression and pain catastrophizing and the HRQoL of patients with IBD. Children with IBD ages 8 to 18 years and their parents were prospectively recruited. Children answered questionnaires on HRQoL while parents completed an assessment of distress, anxiety, depression, and pain catastrophizing. Univariate and multivariate regression models analysis were used to evaluate correlations between parental measures and patient's HRQoL and between the factors related to children health and parental psychological suffering. One hundred patients (45 Crohn disease, 55 ulcerative colitis), 90 mothers and 62 fathers were enrolled. Parents had high levels of distress while anxiety, depression, and pain catastrophizing levels were relatively low. Parental distress had the most substantial correlation with children's HRQoL and was associated with patients' disease activity and recent flares. On multivariate regression analysis, parental factors explained less than 20% of the variance in the children's HRQoL scores. Mothers suffered from psychological alterations more frequently than fathers, but the parental inter-rater agreement was strong in regards to distress and anxiety. Parental distress is high and correlates with the HRQoL of children with IBD. Interventions aimed at evaluating and managing parental distress should be considered during the management of children with IBD.

Longitudinal Impact of Parental Catastrophizing on Child Functional Disability in Pediatric Amplified Pain.

ObjectiveChildren with amplified musculoskeletal pain (AMPS) experience significant functional disability, with impairment in their ability to participate in age-appropriate activities of daily living. Parental factors play an important role in a child’s pain symptoms and treatment outcomes, with parental pain catastrophizing and protective behaviors linked to several maladaptive outcomes for children. Aims of the current study were to examine how parental pain catastrophizing, child pain catastrophizing, and parental protective behaviors longitudinally impacted functional disability for children with AMPS.MethodsArchival data were examined from parent-child dyads presenting to a tertiary pain clinic for treatment of AMPS. Over 1 year, parents completed measures assessing the level of pain catastrophizing, common behavioral responses to child pain, and child functional disability. Children completed measures of pain catastrophizing and functional disability. Measures were collected at initial evaluation, 6-months, and 12-months. Latent growth models (LGM) were conducted to examine how to study variables longitudinally impacted the rate of change in child functional disability.ResultsExamining a comprehensive LGM of study variables, parental catastrophizing emerged as the sole contributing factor to slower improvement in functional disability.ConclusionsThe strong influence of parental pain catastrophizing on functional disability may relate to parents limiting behaviors that promote adaptive coping in children with pain. As such, parents who catastrophize may benefit from specific interventions to increase their use of adaptive behavioral responses, such as redirecting children to complete functional activities and encouraging the use of positive coping skills for pain-related distress.

Pain catastrophizing and medication overuse in patients with chronic migraine

Migraine is a frequent and debilitating primary headache. Pain catastrophizing is a negative set activated in response to anticipated or actual pain. The anticipatory fear of pain, one of its characteristics, has been associated with a greater prescription and use of analgesics. To explore the pain catastrophizing in relation to analgesic overuse and the headache impact on quality of life in patients with chronic migraine. An observational cross-sectional analytical study was performed. Patients older than 18 years with chronic migraine were included, who were given anonymously the Pain Catastrophizing Scale and the Head Impact Test-6. When comparing the incidence of analgesic overuse among patients with clinical pain catastrophizing levels and those without pain catastrophizing, the probability of analgesic overuse was 16 times higher in the first group (odds ratio = 16.06; 95% CI = 5.91-43.61; p < 0.0001). When comparing the presence of a severe migraine impact in patients with and without pain catastrophizing, the probability of a severe migraine impact is approximately eight times greater in the first group (odds ratio = 8.27; 95% CI = 3.19-21.42; p < 0.0001). Clinical levels of pain catastrophizing in patients with chronic migraine might be associated with a higher incidence of analgesic overuse and a greater headache impact on quality of life.

No effect of cognitive behavioral patient education for patients with pain catastrophizing before total knee arthroplasty: a randomized controlled trial

Background and purpose — Pain catastrophizing contributes to acute and long-term pain after total knee arthroplasty (TKA) but currently there are only limited treatment options. This study investigates the effectiveness of patient education in pain coping among patients with moderate to high pain catastrophizing score before TKA. Secondary outcomes were physical function, quality of life, self-efficacy, and pain catastrophizing.Patients and methods — The study was a parallel-group randomized controlled trial including patients with moderate to high levels of pain catastrophizing. 60 patients were recruited from December 2015 to June 2018. The mean age of the patients was 66 (47–82) years and 40 were women. The patients were randomized to either cognitive-behavioral therapy (CBT) based pain education or usual care. The primary outcome measure was pain under activity measured with the Visual Analog Scale (VAS). All outcomes were measured preoperatively, at 3 months, and at 1 year after surgery.Results — We found no difference in the primary outcome measure, VAS during activity, between the 2 groups but both groups had large reductions over time. The CBT-based pain education group reduced their VAS score by 37 mm (95% CI 27–46) and the control group by 40 mm (CI 31–49). We found no statistically significantly differences between the 2 groups in any of the secondary outcomes.Interpretation — Future research is warranted to identify predictors of persistent pain and interventions for the approximately 20% of patients with persisting pain after a TKA.

Factors influencing health status in older people with knee osteoarthritis.

To examine a causal model of health status among older people with knee osteoarthritis. A cross-sectional, correlational design was used with a convenience sample of 220 older Thai people with knee osteoarthritis (mean age 68.96 years; SD = 6.22). Participants were asked to complete a demographic questionnaire, the Pain Catastrophizing Scale, the Tampa Scale of Kinesiophobia, The Medical Outcomes Study Social Support Survey, and the Arthritis Impact Measurement Scales 2-Short Form. Structural Equation Model was used to examine a hypothesized model. Using Chi-square, hypothesized model was statistically nonsignificant. A model of health status fitted with the empirical data and explained 19.2% of variance. Pain catastrophizing had negative direct effect on self-efficacy and health status. Pain catastrophizing also had negative indirect effect on health status through self-efficacy. Self-efficacy and social support had positive direct effects on health status. However, pain-related fear had no direct or indirect effect on health status. Lower level of pain catastrophizing can improve self-efficacy. Increasing of self-efficacy and social support can then lead to improvement on health status. This study highlighted the effect of psychosocial factors on health status. It is necessary to develop a program to minimize pain catastrophizing, improve social support, and promote self-efficacy to improve the health status of older people with knee osteoarthritis.

The Role of Distress and Pain Catastrophizing on the Health-related Quality of Life of Children With Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) can be particularly challenging during the pediatric age with a relevant impact on patient's health-related quality of life (HRQoL). Disease activity accounts for only a small part of the variability in HRQoL, and psychological factors can play a significant role. We aimed to evaluate the impact of patient's distress and pain catastrophizing on children and adolescents with IBD. We prospectively recruited children aged 8 to 18 with IBD and recorded demographic and disease characteristics. Patients answered questionnaires on HRQoL (IMPACT III), distress (distress thermometer [DT]), and pain catastrophizing (Pain Catastrophizing Scale-Children [PCS-C]). Univariate and multivariate regression models analysis were used to evaluate correlations between patients' characteristics, disease activity, distress, pain catastrophizing, and HRQoL. Seventy-one patients were enrolled (median age 13.6, 49.3% Crohn disease, 50.7% ulcerative colitis). Median HRQoL, DT, and PCS-C scores were 78.6 (interquartile range 68.0-87.1), 3.0 (1.0-5.0), and 12.0 (4.0-23.0), respectively. Patient's distress and pain catastrophizing levels significantly correlated with HRQoL. Pain catastrophizing had the strongest impact on HRQoL (Spearman correlation coefficient, ρ = 0.73), followed by distress (ρ = 0.67), and ulcerative colitis severity (ρ = 0.67). The DT and the PCS-C scores were significantly associated (ρ = 0.46). Distress and pain catastrophizing have a significative impact on HRQoL in young patients with IBD. Physicians should recognize the role of these psychological factors and consider cognitive-behavioral therapy to optimize the patient's health.

Interpersonal problems as a predictor of pain catastrophizing in patients with chronic pain.

Background and aims Pain catastrophizing has consistently been related to a variety of negative outcomes within chronic pain conditions, but competing models exist explaining the role of catastrophizing. According to the fear-avoidance model (FAM), catastrophizing is primarily related to the appraisal of pain (i.e. "intrapersonal"), whereas the communal coping model (CCM) suggests that catastrophizing is a strategy to elicit support (i.e. "interpersonal"). In order to examine the interpersonal nature of catastrophizing, this cross-sectional study examined interpersonal problems as a predictor of pain catastrophizing in a sample of patients (n = 97) with chronic pain. Methods Self-report data was taken from patients entering a multidisciplinary, inpatient rehabilitation program. The four quadrants of the Inventory of Interpersonal Problems circumplex model (Hostile-Dominant, Hostile-Submissive, Friendly-Submissive, Friendly-Dominant) were used as predictors of pain catastrophizing in a series of separate, hierarchical regression analyses. Results After controlling for relevant confounding variables such as demographics (gender, age), pain severity, psychiatric symptoms (anxiety/depression, fatigue, insomnia), adverse life experiences and perceived social support, higher levels of Hostile-Dominant interpersonal problems predicted higher levels of pain catastrophizing (p ≤ 0.01, d = 0.56). Conclusions The results add support to the notion that pain catastrophizing may serve a communicative functioning, as predicted by the CCM, with cold, dominant and controlling behaviors as a maladaptive interpersonal strategy to elicit support. It may thus be useful to consider the broader interpersonal context of the individual, and not only the patient's appraisal of pain, when conceptualizing the role of pain catastrophizing in patients with chronic pain. Implications Future psychosocial research and treatment of chronic pain could be informed by including interpersonal theory as a useful theoretical framework, which may help shed more light on how interpersonal problems relates to pain catastrophizing.

Linking Nonrestorative Sleep and Activity Interference Through Pain Catastrophizing and Pain Severity: An Intraday Process Model Among Individuals With Fibromyalgia

Nonrestorative sleep is a key diagnostic feature of the musculoskeletal pain disorder fibromyalgia and is robustly associated with poor physical functioning, including activity interference. However, the mechanisms through which nonrestorative sleep elicits activity interference among individuals with fibromyalgia at the within-person level remain unclear. The present study tested the following 3-path mediation model, using data gathered from a 21-day electronic daily diary in 220 individuals with fibromyalgia: previous night nonrestorative sleep → morning pain catastrophizing → afternoon pain severity → end-of-day activity interference. Results of multilevel structural equation modeling supported the 3-path mediation model. Previous night's nonrestorative sleep and morning pain catastrophizing were also directly related to end-of-day activity interference. Previous night nonrestorative sleep did not significantly predict afternoon pain severity while controlling for the effect of morning pain catastrophizing. Greater nonrestorative sleep during the previous night and a higher level of morning pain catastrophizing appear to serve as risk factors for experiencing greater daily pain and activity interference later in the day. These findings point to the potential utility of targeted interventions that improve both sleep quality and pain catastrophizing to help individuals with chronic pain engage in important daily activities despite experiencing pain. PerspectiveThis study provides a better understanding of how nonrestorative sleep is associated with daily activity interference among individuals with fibromyalgia. An intervention that targets attenuating nonrestorative sleep and pain catastrophizing may help improve daily physical functioning of this population.

The association between pain catastrophizing, physical function and pain in a cohort of patients undergoing knee arthroplasty

BackgroundPain catastrophizing contributes to acute and long-term pain after knee arthroplasty (KA), but the association between pain catastrophizing and physical function is not clear.We examined the association between preoperative pain catastrophizing and physical function one year after surgery, as well as differences in physical function, pain and general health in two groups of patients with high and low preoperative pain catastrophizing score.MethodsWe included 615 patients scheduled for KA between March 2011 and December 2013. Patients completed The Pain Catastrophizing Scale (PCS) prior to surgery. The Oxford Knee Score (OKS), Short Form-36 (SF-36) and the EuroQol-5D (EQ-5D) were completed prior to surgery, and 4 and 12 months after the surgery.ResultsOf the 615 patients, 442 underwent total knee arthroplasty (TKA) and 173 unicompartmental knee arthroplasty (UKA). Mean age was 67.3 (SD: 9.7) and 53.2% were females. Patients with PCS > 21 had statistically significantly larger improvement in mean OKS for both TKA and UKA than patients with PCS < 11; 3.2 (95% CI: 1.0, 5.4) and 5.4 (95% CI: 2.2, 8.6), respectively. Furthermore, patients with preoperative PCS > 21 had statistically significantly lower OKS, SF-36 and EQ-5D and higher pain score than patients with PCS < 11 both preoperatively and 4 and 12 months postoperatively.ConclusionsPatients with high levels of preoperative pain catastrophizing have lower physical function, more pain and poorer general health both before and after KA than patients without elevated pain catastrophizing.

A Network Analysis of Potential Antecedents and Consequences of Pain-Related Activity Avoidance and Activity Engagement in Adolescents.

This study sets out to identify potential daily antecedents and consequences of pain-related activity avoidance and engagement behavior in adolescents with chronic pain. Adolescents (N = 65, Mage = 14.41) completed baseline self-reports and a diary for 14 days. Afternoon and evening reports were used to infer a network structure of within-day associations between pain intensity, pain-related fear, pain catastrophizing, affect, and pain-related activity avoidance and engagement behavior. Baseline psychological flexibility was examined as a potential resilience factor. Activity avoidance in the evening was predicted by pain-related fear and avoidance earlier that afternoon. Activity engagement was predicted by positive affect and activity engagement in the afternoon. Pain-related behavior in the afternoon was not related to subsequent changes in pain intensity, pain-related fear, pain catastrophizing, or affect. Pain-related fear in the afternoon was predictive of increased levels of pain and pain catastrophizing in the evening. Both pain-related fear and pain catastrophizing in the evening were predicted by negative affect in the afternoon. Psychological flexibility was associated with lower levels of daily activity avoidance and buffered the negative association between pain intensity and subsequent activity engagement. This study provides insight into unique factors that trigger and maintain activity avoidance and engagement and into the role of psychological flexibility in pediatric pain. Future work should focus on both risk and resilience factors and examine the role of psychological flexibility in chronic pediatric pain in greater detail.

Multiple diagnoses, increased kinesiophobia? - Patients with high kinesiophobia levels showed a greater number of temporomandibular disorder diagnoses

ObjectivesThe aim of this study was to empirically derive subgroups according to pain-related fear of movement beliefs using cluster analysis within a sample of TMD patients and asymptomatic volunteers. Methods129 volunteers participated in this cross-sectional study (34.78, standard deviation [SD]: 12.49 years; 92 TMD patients and 37 symptom-free volunteers). Mechanical pain sensitivity through pressure pain threshold (PPT) on orofacial and remote sites, kinesiophobia, pain catastrophizing, anxiety and depression were assessed. A cluster analysis was used to derive subgroups according to kinesiophobia scores (TSK/TMD). ResultsThree subgroups were derived: cluster 1 (high kinesiophobia [n = 53], TSK score: 33, SD[standard deviation] = 2.9), cluster 2 (moderate kinesiophobia [n = 50], TSK score: 26.2, SD = 2.14) and cluster 3 (no/low kinesiophobia [n = 26], TSK score 12.12, SD = 2.08) which included patients with higher overall PPT and lower scores on psychosocial variables. The group with high kinesiophobia showed high levels of pain catastrophizing, anxiety, and orofacial pain-related disability compared to the other subgroups and mechanical pain hyperalgesia in remote site compared to the low-kinesiophobia group. Also, we found a greater prevalence of triple diagnosis for the high-kinesiophobia subgroup compared to the moderate kinesiophobia group - odds ratio: 12.6 (95% confidence interval [CI]: 3.31–43.52, p < 0.01). ConclusionThese results suggested that patients with TMD and higher levels of kinesiophobia beliefs may show a more complex clinical feature, with high psychosocial distress, widespread mechanical pain sensitivity, and a more complex TMD disorder. In this way, we suggest a relationship between the number of TMD diagnoses and kinesiophobia severity.

Surgeon identification of pain catastrophizing versus the Pain Catastrophizing Scale in orthopedic patients after routine surgical consultation

A high level of pain catastrophizing has negative influences on outcomes in many surgical disciplines. Our purpose was to determine whether surgeons are able to accurately identify high catastrophizing in orthopedic patients after routine clinical consultation. In this prospective study, English-literate patients aged 18 years or older were assessed by 1 of 11 orthopedic surgeons. Patients completed the Pain Catastrophizing Scale (PCS), and the surgeon rated each patient as having a high or low level of catastrophizing after the clinical encounter. We calculated accuracy and agreement of surgeon assessment with the PCS at a cut-off score of 30 (score ≥ 30 = high level of catastrophizing) and used multivariate testing to determine whether patient age or sex, surgeon experience or subscores of the PCS (rumination, magnification and helplessness) influenced surgeon accuracy. Among 203 patients (109 women and 94 men), the mean PCS score was 18.4 (standard deviation 12.9), with no sex difference and no significant correlation to patient age. Of the 40 patients who scored 30 or more on the PCS, 22 (55%) were not identified as having high levels of catastrophizing by their surgeon. Accuracy was 0.72, and agreement was 0.2. Female patients were more likely than male patients to be identified as high catastrophizing regardless of PCS score (odds ratio 2.0, 95% confidence interval 1.04–4.0). Surgeons were not able to accurately identify patients with high levels of pain catastrophizing during routine initial consultation. In considering which patients may most benefit from interventions to improve coping and reduce catastrophizing, explicitly measuring pain catastrophizing will be required.

Pain catastrophizing, anxiety, and depression in hip pathology.

Psychological factors play a critical role in patient presentation, satisfaction, and outcomes. Pain catastrophizing, anxiety, and depression are important to consider, as they are associated with poorer outcomes and are potentially modifiable. The aim of this study was to assess the level of pain catastrophizing, anxiety, and depression in patients with a range of hip pathology and to evaluate their relationship with patient-reported psychosocial and functional outcome measures. Patients presenting to a tertiary-centre specialist hip clinic were prospectively evaluated for outcomes of pain catastrophizing, anxiety, and depression. Validated assessments were undertaken such as: the Pain Catastrophizing Scale (PCS), the Hospital Anxiety Depression Scale (HADS), and the 12-Item Short-Form Health Survey (SF-12). Patient characteristics and demographics were also recorded. Multiple linear regression modelling, with adaptive least absolute shrinkage and selection operator (LASSO) variable selection, was used for analysis. A total of 328 patients were identified for inclusion, with diagnoses of hip dysplasia (DDH; n = 50), femoroacetabular impingement (FAI; n = 55), lateral trochanteric pain syndrome (LTP; n = 23), hip osteoarthrosis (OA; n = 184), and avascular necrosis of the hip (AVN; n = 16) with a mean age of 31.0 years (14 to 65), 38.5 years (18 to 64), 63.7 years (20 to 78), 63.5 years (18 to 91), and 39.4 years (18 to 71), respectively. The percentage of patients with abnormal levels of pain catastrophizing, anxiety, or depression was: 22.0%, 16.0%, and 12.0% for DDH, respectively; 9.1%, 10.9%, and 7.3% for FAI, respectively; 13.0%, 4.3%, and 4.3% for LTP, respectively; 21.7%, 11.4%, and 14.1% for OA, respectively; and 25.0%, 43.8%, and 6.3% for AVN, respectively. HADS Anxiety (HADSA) and Hip Disability Osteoarthritis Outcome Score Activities of Daily Living subscale (HOOS ADL) predicted the PCS total (adjusted R2 = 0.4599). Age, HADS Depression (HADSD), and PCS total predicted HADSA (adjusted R2 = 0.4985). Age, HADSA, patient's percentage of perceived function, PCS total, and HOOS Quality of Life subscale (HOOS QOL) predicted HADSD (adjusted R2 = 0.5802). Patients with hip pathology may exhibit significant pain catastrophizing, anxiety, and depression. Identifying these factors and understanding the impact of psychosocial function could help improve patient treatment outcomes. Perioperative multidisciplinary assessment may be a beneficial part of comprehensive orthopaedic hip care. Cite this article: Bone Joint J 2019;101-B:800-807.
