The study had two purposes: (a) to examine the relationships among coping strategies measured by the Coping Strategies Questionnaire (CSQ) (1), the Vanderbilt Pain Management Inventory (VPMI) (2), and the Ways of Coping Inventory (WOC) (3) and identify the higher-order composite factors representing these relationships; and (b) to determine the degree to which individual coping scale scores and composite coping factor scores could explain variability in the pain intensity and pain-related activity interference reported by young adults. Measures of pain coping were collected from 206 young adults using the CSQ, VPMI, and WOC, along with measures of pain intensity, pain location, and the extent to which pain interfered with daily activities. Results indicated considerable variability in the reported frequency of use of pain-coping strategies and in pain intensity, location, and activity interference. ⋯ The degree to which individual scale scores and composite factor scores explained variability in pain intensity and activity interference variables was determined through a series of multiple regression analyses. The results revealed that individual scale scores, particularly the CSQ scales of catastrophizing and praying or hoping, were best able to explain the variance in measures of pain and activity interference. Taken together, these findings provide further support for the importance of coping variables in explaining the experience of pain and adjustment in young adults.

We have previously reported that patients with temporomandibular disorders (TMD) exhibit enhanced sensitivity to experimentally evoked pain (1); however, the clinical relevance of this increased pain sensitivity remains unclear. The purpose of this study was to investigate the relationship of experimental pain sensitivity to clinical and psychosocial variables among patients with TMD. ⋯ The results suggest that ischemic pain tolerance is a clinically relevant marker of pain sensitivity in TMD patients. These findings are consistent with the hypothesis that impairments in CNS inhibitory pathways may contribute to the pain associated with TMD.

Gender differences in reports of chronic pain, in coping responses to the consequences of painful conditions, and in the use of health care services have recently received considerable attention. This report examines the gender effects of referral practices to a chronic pain specialty clinic and the nature of the relationship between health care needs and use of health care services. This historical cohort analytic survey of 571 patients referred to the pain clinic assessed them by gender for selected referral variables through a chart review, and randomly sampled (n = 222) these patients' current adjustment and health service use through mailed questionnaires or telephone interview. ⋯ Men's use of services, on the other hand, was explained in part by meaning alone. The importance of gender, differences in the role that social support and meaning variables play in predicting psychosocial adjustment to chronic pain is elaborated in this study. The interaction effects between health care need and gender to explain variations in use of health care services indicates that users of services varied in ways that suggest a bias or barrier of their own or of service providers to access services.

This study was designed to test the stability of recent findings by the authors showing that 40% of the McGill Pain Questionnaire (MPQ) descriptors of pain sensation were not classifiable in any MPQ subcategory because of incomprehension, underuse, or ambiguity of usage. The study also was intended to determine the pain intensity ratings for the descriptors and how they relate to the original ratings provided by Melzack and Torgerson. ⋯ A parsimonious set of 32 words can be adopted from the MPQ for efficient and unambiguous use in the clinical assessment of pain.

Randomized Controlled Trial Clinical Trial
Manipulation of transcutaneous electrical nerve stimulation variables has no effect on two models of experimental pain in humans.
Two separate studies investigated the hypoalgesic effect of manipulation of Transcutaneous Electrical Nerve Stimulation (TENS) parameters on two models of experimental pain: the Submaximal Effort Tourniquet Technique and cold-pressor pain. For the first study, 32 healthy subjects (16 male and 16 female) attended once for the purpose of cold-pressor pain induction that involved immersion of the nondominant hand in a water bath at 0 degree C. Subjects were allocated to Control, Placebo, or 1 of 2 treatment groups (110 or 4-Hz TENS). ⋯ Measurements of "current pain intensity" and "worst pain experienced" were obtained via the Visual Analogue Scale (VAS) and the McGill Pain Questionnaire (MPQ), respectively. Analysis of variance performed on both sets of collected data revealed no significant differences between any of the groups, thus indicating no apparent relevance of manipulation of TENS parameters using these models of pain. Several hypotheses are suggested to explain these findings.
