Both race and socioeconomic status (SES) contribute to disparities. We assessed the relative roles of neighborhood socioeconomic status (nSES) and race in the chronic pain experience for young adults (<50 years old). Data from a tertiary care pain center was matched to 2000 US Census data to examine the role of race and nSES on chronic pain and its sequelae in 3,730 adults (9.7% black, 61% female) 18 to 49 years old (37 ± 8 years). Blacks had significantly more pain and disability and lived in lower SES neighborhoods. Living in a lower SES neighborhood was associated with increased sensory, affective, and "other" pain, pain-related disability, and mood disorders. Race was independently associated with affective and "other" pain on the McGill Pain Questionnaire scales, and both disability factors. Racial disparities in sensory pain and mood disorders were mediated by nSES. In every case, race and neighborhood SES played important roles in the outcomes for chronic pain. Age was related to both disability outcomes. Gender was associated with voluntary disability and mood disorders, with men displaying worse outcomes. ⋯ Important racial- and SES-related variability in pain related outcomes in young adults with chronic pain were defined. Black race was associated with neighborhood SES, and black race plays an important role in pain outcomes beyond neighborhood SES.

Parental responses to children with chronic pain have been shown to influence the extent of the child's functional disability, but these associations have not been well studied in relation to children's pain-related school functioning. The current study tests the hypothesis that parental pain catastrophizing and parental protective responses to child pain influence the extent of school impairment in children with chronic pain. A mediational model was tested to determine whether parental protective behaviors serve a mediating role between parental pain catastrophizing and child school impairment. ⋯ Results show that, controlling for the known influences of pain intensity and child depressive symptoms, parental pain catastrophizing and parental protective responses to child pain each independently predict child school attendance rates and reports of overall school impairment. Parental protectiveness was found to mediate the association between parental cognitions (i.e., parent pain catastrophizing) and child school functioning outcomes. These findings underscore the importance of intervening with parents to foster parental responses to child pain that help children engage and succeed in the school environment despite pain.

The postthoracotomy pain syndrome (PTPS) has a prevalence of 30% to 40%. Although intraoperative nerve damage during thoracotomy has been demonstrated, it has not been clearly linked to PTPS and detailed quantitative sensory characterization data have so far not been presented, comparing PTPS and pain-free patients. ⋯ Neurophysiological assessments indicate nerve injury to be common in pain and pain-free patients after thoracotomy. The combination of increased thresholds together with hyperesthesia, suggests consequences of nerve injury to be more pronounced in PTPS patients.

Expanding the social communication model of pain: are adult attachment characteristics associated with observers' pain-related evaluations?
Evaluations of another's pain can have important implications in medical, employment, and social settings. Influenced by the Social Communication Model of Pain, this vignette-based study investigated the potential influence of characteristics of the person being evaluated (viz., the coping strategy used by an individual with chronic pain depicted in a vignette) and characteristics of those making evaluations (viz., self-reported attachment anxiety and avoidance of the study participants). The main hypothesis was that participants higher in attachment avoidance would be more critical in their evaluations than those lower in attachment avoidance. ⋯ The current findings suggest that chronic pain patients' coping styles influence evaluations made about them, and that evaluators' gender and attachment characteristics also have important effects on such evaluations.

The Japanese version of the 2010 American College of Rheumatology Preliminary Diagnostic Criteria for Fibromyalgia and the Fibromyalgia Symptom Scale: reliability and validity.
The aim of this study was to investigate the reliability and the validity of the Japanese version of the 2010 American College of Rheumatology Preliminary Diagnostic Criteria for Fibromyalgia (ACR 2010-J), and its quantification scale, the Fibromyalgia Symptom Scale (FS-J). In this study, we divided patients with chronic pain without psychiatric disorders other than depression into two groups according to the 1990 ACR Diagnostic Criteria for Fibromyalgia, a fibromyalgia group and a non-fibromyalgia group (rheumatoid arthritis, osteoarthritis, and gout). Patients in both groups were assessed using the ACR 2010-J and FS-J. ⋯ With a cutoff score of 10, the positive likelihood ratio was 10.1. Our findings indicate that the ACR 2010-J and FS-J have high reliability and validity, and are useful for assessing fibromyalgia in Japanese populations with chronic pain. As regards the positive likelihood ratio, that of the FS-J might be suitable as a positive test.
