Randomized Controlled Trial
Randomized Trial of a Low-Literacy Chronic Pain Self-Management Program: Analysis of Secondary Pain and Psychological Outcome Measures.
Based on input of rural, largely Hispanic persons with chronic pain, a low-literacy, 6-month self-management program was developed, drawing on elements of existing pain toolkits. In a randomized trial, low-income, primarily Hispanic patients with chronic pain received the program in 6 sessions of 1-on-1 meetings with a trained health educator in clinic or in 8 group lectures by experts in the community. Intention-to-treat analyses in linear mixed-effects models were conducted for 5 secondary outcomes at 6 months, including Brief Pain Inventory pain severity and interference, Patient Health Questionnaire-9, 12-Item Short-Form Survey Mental Component Summary, and Tampa Scale for Kinesiophobia-11. ⋯ In intention-to-treat analyses, both arms improved on 4 of 5 measures (all P ≤ .001) versus baseline, with clinically significant changes in Brief Pain Inventory pain severity and interference. Improvement in multiple outcomes after this chronic pain self-management program for low-income patients warrants further study. PERSPECTIVE: In an evaluation of a low-literacy, 6-month chronic pain self-management program, similar improvements were observed among primarily Hispanic participants whether the intervention was delivered by a health educator or in groups with lectures from experts.

Athletes seem to have higher pain tolerance than the normally active population. It is unknown whether psychological factors contribute to their supranormal pain tolerance. The aim of this pilot study was to examine pain-related psychological processes in ultramarathon runners ('ultrarunners') and to explore whether psychological factors mediate the elevated pain tolerance displayed by ultrarunners. ⋯ Our results suggest that ultrarunners have lower levels of pain-related anxiety than the general population and that their supranormal pain tolerance is partially mediated by reduced pain-related escape and avoidance behaviors. PERSPECTIVE: This study investigated whether psychological factors contribute to the supranormal pain tolerance displayed by ultrarunners. It found that ultrarunners have lower levels of pain-related anxiety than nonrunning controls and that reduced pain-related escape and avoidance behaviors partially mediate their elevated pain tolerance.

Randomized Controlled Trial
The Pain Course: 12- and 24-Month Outcomes From a Randomized Controlled Trial of an Internet-Delivered Pain Management Program Provided With Different Levels of Clinician Support.
Little is known about the long-term outcomes of emerging Internet-delivered pain management programs. The current study reports the 12- and 24-month follow-up data from a randomized controlled trial (n = 490) of an Internet-delivered pain management program, the Pain Course. The initial results of the trial to the 3-month follow-up have been reported elsewhere. ⋯ PERSPECTIVE: This article presents the long-term outcome data of an established Internet-delivered pain management program for adults with chronic pain. The clinical improvements observed during the program were found to be maintained at the 12- and 24-month follow-up marks. This finding indicates that these programs can have lasting clinical effects.

Persistent Post-Mastectomy Pain (PPMP) is a common condition that can follow surgeries for breast cancer, the most common cancer in women. Because of the frequency of PPMP and its potential severity, it has received increasing research attention. This manuscript reviews the recent research literature, beginning with a brief history and then relevant medical, surgical, demographic, and psychosocial risk factors. ⋯ The review concludes with a discussion of directions for future research and treatment that might reduce the incidence and impact of PPMP on breast cancer survivors. PERSPECTIVE: This article describes current research literature involving mechanisms, risks, and treatments related to persistent post-mastectomy pain. Implications of research findings also are discussed for pre- and post-surgical approaches to pain management, current treatments, and promising research directions.

Older adults frequently report pain; cross-sectional studies have shown that pain is associated with worse cognitive function. However, longitudinal studies are lacking. We prospectively studied 441 participants without dementia, including 285 with pain, aged 65 years and older, enrolled in the Central Control of Mobility in Aging study, a prospective cohort study. ⋯ We did not find that pain is associated with incident cognitive impairment in general, but among older adults with pain, a high level of pain is associated with increased risk of developing incident memory impairment. PERSPECTIVE: Our study results suggest that high levels of pain may contribute to incident memory impairment. Further research is needed to determine whether a high level of chronic pain is a modifiable risk factor for cognitive impairment in older adults.
