Can people catastrophize barriers? An exploratory analysis of the association between pain catastrophizing and perceptions of environmental factors

Background

Measurement of the environment is taking on increased importance for understanding variability in participation. Most measures of the environment use subjective ratings, yet little is known about how people appraise the environment.

The psychological burden of disease among patients undergoing cervical spine surgery: Are we underestimating our patients’ inherent disability?

BackgroundStudies have utilized psychological questionnaires to identify the psychological distress among certain surgical populations.Research QuestionIs there an additional psychological burden among patients undergoing surgical treatment for their symptomatic degenerative cervical disease?Materials and methodsPatients > 18 years of age with symptomatic, degenerative cervical spine disease were included and prospectively enrolled. Correlations and multivariable logistic regression analysis assessed the relationship between these mental health components (PCS, FABQ) and the severity of disability described by the NDI, EQ-5D, and mJOA score. Patient distress scores were compared to previously published benchmarks for other diagnoses.Results47 patients were enrolled (age: 56.0 years,BMI: 29.7 kg/m²). Increasing neck disability and decreasing EQ-5D were correlated with greater PCS and FABQ(all P < 0.001). Patients with severe psychological distress at baseline were more likely to report severe neck disability, while physician-reported mJOA had weaker associations. Compared to historical controls of lumbar patients, patients in our study had greater levels of psychological distress, as measured by FABQ (40.0 vs. 17.6; P < 0.001) and PCS (27.4 vs. 19.3;P < 0.001).Discussion and ConclusionDegenerative cervical spine patients seeking surgery were found to have a significant level of psychological distress, with a large portion reporting severe fear avoidance beliefs and catastrophizing pain at baseline. Strong correlation was seen between patient-reported functional metrics, but less so with physician-reported signs and symptoms. Additionally, this population demonstrated higher psychological burden in certain respects than previously identified benchmarks of patients with other disorders. Preoperative treatment to help mitigate this distress, impact postoperative outcomes, and should be further investigated.Level of EvidenceLevel III.     

Pain in childbirth and postpartum recovery – The role of catastrophizing

This prospective study investigated how pain catastrophizing was related to labor pain intensity and physical recovery after childbirth. Eighty‐eight women giving birth for the first time completed the first questionnaire before delivery. Eighty‐two of those returned the second questionnaire after delivery. Participants were classified as catastrophizers (n=38) or non‐catastrophizers (n=44) based on their scores on the Pain Catastrophizing Scale. Comparison of the groups showed that catastrophizers anticipated and experienced more intense pain (p<.0125) and had poorer physical recovery (p<.0125), measured as the level of self‐reported functioning in activities of daily living, than non‐catastrophizers. These results extend the association between catastrophizing and pain, to pain and recovery in childbirth and provide support for the fear‐avoidance model. It is concluded that pain catastrophizing plays a role in the experience of pain in childbirth and postpartum recovery. Further research is needed to identify appropriate interventions for catastrophizing women during the latter part of pregnancy.     

Spinal cord injury‐related pain in rehabilitation: A cross‐sectional study of relationships with cognitions,mood and physical function

Although psychological aspects of SCI‐related pain have been investigated in those with chronic pain, little data is available regarding these factors in those early in the course of the injury. Using a sample admitted for SCI rehabilitation, this paper describes the relationships between usual pain intensity, mood, disability and both pain and SCI‐related psychological factors. The sample were largely similar to other samples of individuals with SCI‐related chronic pain in terms of mood, but were noted to be less catastrophic in their thinking about pain than a comparative pain clinic sample. They also reported SCI self‐efficacy and acceptance scores consistent with other SCI samples. Compared with other SCI populations there were mixed findings in relation to physical disability. Consistent with previous findings in chronic pain SCI samples, usual pain intensity was found to have a strong relationship with symptoms of anxiety and depression, and pain‐related life interference. SCI acceptance was significantly negatively associated with depression scores, pain catastrophizing was significantly positively associated with both anxiety and depression scores, and SCI self‐efficacy was significantly negatively associated with both anxiety and depression scores. SCI self‐efficacy was also significantly positively associated with physical function scores. These findings suggest that pain‐related psychological factors may have importance even early in the clinical course following SCI, but that it is important, however, to consider more general SCI‐related psychological factors alongside them. In addition, these findings suggest the possibility that early interventions based upon the cognitive behavioural treatment of pain may be integrated into SCI rehabilitation programmes.     

Factorial Validity of the English-Language Version of the Pain Catastrophizing Scale–Child Version

The Pain Catastrophizing Scale (PCS) was developed in English to assess 3 components of catastrophizing (rumination, magnification, helplessness). It has been adapted for use and validated with Flemish-speaking children (Pain Catastrophizing Scale for Children [PCS-C]) and French-speaking adolescents. The PCS-C has been back-translated to English and used extensively in research with English-speaking children; however, the factorial validity of the English PCS-C has not been empirically examined. This study assessed the factor structure of the English PCS-C among a community sample of 1,006 English-speaking children (aged 8–18 years). Exploratory factor analysis was conducted using a random subsample (n = 504) to assess the underlying factor structure. Items with poor factor loadings were removed. Confirmatory factor analysis, using the second subsample (n = 502), was used to cross-validate the factor structure revealed by exploratory factor analysis and compare it to the original 3-factor model and other model variants. Exploratory factor analysis revealed that the original PCS-C and a revised 3-factor model comprising 11 of the original 13 PCS-C items, all loading on their original factors, provided adequate fit to the data. The revised model provided statistically better fit to the data compared to all other model variants, suggesting that the English PCS-C may be better understood using a revised 11-item oblique 3-factor model.     

Contextual determinants of pain judgments

The objective of this study was to examine the influence of variations in contextual features of a physically demanding lifting task on the judgments of others' pain. Healthy undergraduates (n=98) were asked to estimate the pain experience of chronic pain patients who were filmed while lifting canisters at different distances from their body. Of interest was whether contextual information (i.e., lifting posture) contributed to pain estimates beyond the variance accounted for by pain behavior. Results indicated that the judgments of others' pain varied significantly as a function of the contextual features of the pain-eliciting task; observers estimated significantly more pain when watching patients lifting canisters positioned further away from the body than canisters closest from the body. Canister position contributed significant unique variance to the prediction of pain estimates even after controlling for observers' use of pain behavior as a basis of pain estimates. Correlational analyses revealed that greater use of the contextual features when judging others' pain was related to a lower discrepancy (higher accuracy) between estimated and self-reported pain ratings. Results also indicated that observers' level of catastrophizing was associated with more accurate pain estimates. The results of a regression analysis further showed that observers' level of catastrophizing contributed to the prediction of the accuracy of pain estimates over and above the variance accounted for by the utilisation of contextual features. Discussion addresses the processes that might underlie the utilisation of contextual features of a pain-eliciting task when estimating others' pain.     

Mindfulness, functioning and catastrophizing after multidisciplinary pain management for chronic low back pain

We examined mindfulness in people with chronic low back pain who were attending a multidisciplinary pain management programme. Participants completed questionnaires at baseline (n=116) and after a 3-month cognitive-behaviourally informed multidisciplinary intervention (n=87). Self-reported mindfulness was measured before and after the intervention, and relationships were explored between mindfulness, disability, affect and pain catastrophizing. Mindfulness increased following participation in the intervention, and greater mindfulness was predictive of lower levels of disability, anxiety, depression and catastrophizing, even when pain severity was controlled. Mediator analyses suggested that the relationship between mindfulness and disability was mediated by catastrophizing. It is possible that cognitive-behavioural interventions and processes can affect both catastrophizing and mindfulness.     

Medical evaluation of children with chronic abdominal pain: Impact of diagnosis,physician practice orientation,and maternal trait anxiety on mothers’ responses to the evaluation

This study examined the effects of diagnosis (functional versus organic), physician practice orientation (biomedical versus biopsychosocial), and maternal trait anxiety (high versus low) on mothers’ responses to a child’s medical evaluation for chronic abdominal pain. Mothers selected for high (n = 80) and low (n = 80) trait anxiety imagined that they were the mother of a child with chronic abdominal pain described in a vignette. They completed questionnaires assessing their negative affect and pain catastrophizing. Next, mothers were randomly assigned to view one of four video vignettes of a physician-actor reporting results of the child’s medical evaluation. Vignettes varied by diagnosis (functional versus organic) and physician practice orientation (biomedical versus biopsychosocial). Following presentation of the vignettes, baseline questionnaires were re-administered and mothers rated their satisfaction with the physician. Results indicated that mothers in all conditions reported reduced distress pre- to post-vignette; however, the degree of the reduction differed as a function of diagnosis, presentation, and anxiety. Mothers reported more post-vignette negative affect, pain catastrophizing, and dissatisfaction with the physician when the physician presented a functional rather than an organic diagnosis. These effects were significantly greater for mothers with high trait anxiety who received a functional diagnosis presented by a physician with a biomedical orientation than for mothers in any other condition. Anxious mothers of children evaluated for chronic abdominal pain may be less distressed and more satisfied when a functional diagnosis is delivered by a physician with a biopsychosocial rather than a biomedical orientation.
