Although evidence supports the importance of pain-related thoughts (ie, cognitive content, or what people think) as predictors of pain and pain-related function, evidence regarding the role of cognitive processes (ie, how people think about pain, eg, by accepting pain, not making judgments about pain, or being absorbed by the pain experience) in adjustment to chronic pain is in its early stages. Using baseline data from a clinical trial of individuals with chronic low back pain (N = 327), the study aimed to increase knowledge regarding the associations between cognitive processes, pain intensity, pain interference, and depression. The results indicate that a number of cognitive processes are significantly related to pain intensity when controlling for catastrophizing, although the pattern of associations found was opposite to those anticipated. ⋯ Longitudinal and experimental studies to evaluate the causal nature of the associations identified are warranted. PERSPECTIVE: The study findings highlight the potential importance of cognitive process variables (ie, how people think) in adjustment to chronic pain. Research to evaluate cognitive processes as potential mechanism variables in pain treatment is warranted.

Observational Study
Unravelling the Left-Right Judgment Task in Chronic Low Back Pain: Insights through Behavioural, Electrophysiological, Motor Imagery, and Bodily Disruption Perspectives.
Bodily disruptions have been consistently demonstrated in individuals with chronic low back pain. The performance on the left-right judgment task has been purposed as an indirect measure of the cortical proprioceptive representation of the body. It has been suggested to be dependent on implicit motor imagery, although the available evidence is conflicting. ⋯ The absence of differences in the reaction times for the left-right judgment task between both groups, along with inconsistencies in self-reported and quantitative sensory testing data, could question the involvement of implicit motor imagery in solving the task. In conclusion, our results suggest disrupted attentional processing in participants with chronic low back pain to solve the left-right judgment task. PERSPECTIVE: Although there are no differences in the performance of the left-right judgment task (hits, reaction times) between chronic low back pain patients and controls, the analysis of event-related potentials revealed that patients require a higher cognitive load, measured by N1 peak amplitude.

Previous studies have established a core outcome set for pediatric chronic pain clinical trials. The aim of this research was to establish which outcomes young people and parents considered important to measure during treatment for chronic musculoskeletal pain. To the best of our knowledge, this is the first study to explore which outcomes could be used to tailor interventions within a clinical setting. ⋯ Overall, the research highlighted the need for clinical guidance on which outcome domains to measure during the treatment course to gauge treatment effectiveness and optimally tailor interventions. PERSPECTIVE: This study established the range of outcomes that were important to young people and their parents during treatment for chronic musculoskeletal pain. The findings show how young people and parents have different outcome preferences and how their outcome focus changes during the treatment course.

In response to the opioid epidemic and high rates of chronic pain among the veteran population, the U. S. Department of Veterans Affairs implemented the TelePain-Empower Veterans Program (EVP), a nonpharmacological pain management program for veterans. ⋯ These descriptive data should be triangulated with quantitative data to objectively assess participant TelePain-EVP outcomes and associated participant characteristics. PERSPECTIVE: A qualitative evaluation of a telehealth program to manage chronic pain, guided by the CFIR framework, identified determinants of program implementation. Additionally, participants reported improvements in pain management coping skills, interpersonal relationships, and sense of community, but no self-reported reductions in pain or medication use.

Evening chronotype individuals experience pain more often than morning chronotypes, but relationships with pain sensitivity have rarely been studied. We examined whether chronotype is associated with pressure pain sensitivity, with special reference to mental health disorders, insomnia, and chronic musculoskeletal (MSK) pain as potential moderating factors. The study sample consisted of members of the Northern Finland Birth Cohort 1966 aged 46. ⋯ These results emphasize the role of chronotype in pain sensitivity and add an understanding of pain experience in light of innate circadian types. PERSPECTIVE: Male evening chronotypes are more sensitive to pain than morning chronotypes. Diagnosed mental health disorders in particular indicate a low pain threshold for evening chronotype males.
