Using data from the European Social Survey (ESS) 2014, this study presents an update of pain prevalence amongst men and women across Europe and undertakes the first analysis of socioeconomic inequalities in pain. ⋯ This is a pan European study that has explored socioeconomic inequalities in pain. Across Europe, pain is more prevalent in people of lower socioeconomic position; these pain inequalities were most significant for hand/arm pain, and least significant for back/neck pain.

In this eye tracking study, we evaluated pain-related biases in orienting and maintenance of gaze within impending touch versus impending pain tasks and examined features of pain resilience as individual difference influences on potential biases. ⋯ Gaze biases were assessed within a comparatively benign "impending touch" paradigm versus a higher threat, impending pain task. Early capture and maintenance of gaze towards pain images were more pronounced on the latter task, although pain resilient participants were able to disengage more easily from pain images signalling possible pain.

Randomized Controlled Trial Clinical Trial
Differences in Long-Term Physical Activity Trajectories among Individuals with Chronic Widespread Pain: A Secondary Analysis of a Randomized Controlled Trial.
Little is known about long-term physical activity (PA) maintenance in those with chronic widespread pain (CWP) following an exercise intervention. This study examined PA over time to identify the existence and characteristics of subgroups following distinct PA trajectories. ⋯ Chronic pain can be a major barrier to engaging in exercise, a popular self-management strategy. Our findings identify three distinct long-term physical activity trajectories for individuals receiving the same exercise intervention. This suggests an approach by health care providers which identifies individuals who would benefit from additional support to enhance initiation and long-term physical activity maintenance could deliver better outcomes for such patients.

Cutting is the most common method of non-suicidal self-injury (NSSI) to reduce inner tension in patients with Borderline Personality Disorder (BPD). Aim of this study was to compare pain perception induced by an incision and by application of a surrogate model for sharp mechanical pain (a non-invasive "blade") in BPD. ⋯ Patients with Borderline Personality Disorder (BPD) who engage in non-suicidal self-injury (NSSI) report less pain in response to phasic nociceptive stimuli. In comparing an invasive pain stimulus to phasic nociceptive stimuli in BPD patients, the "blade" as non-invasive surrogate model for sharp mechanical pain in psychiatric patients is used. In contrast to healthy volunteers, BPD patients do not report significant affective ratings and specifically display a reduced sensory component for sharpness.

As a complex multidimensional construct, fatigue may play an important role in the physical and psychosocial functioning of youth with chronic pain. Based on a model previously tested in adults, the current study similarly utilized patient-reported outcomes measurement system (PROMIS) to examine how fatigue contributes to functional outcomes for youth with chronic pain. The model tested self-reported ratings of pain intensity, depressive symptoms and sleep disturbance as predictors of outcomes (mobility, pain-related interference and school functioning) as mediated by ratings of fatigue. ⋯ This cross-sectional study highlights fatigue as a potential clinical target by applying a path analytic model to understand its possible significance and distinction from overlapping constructs such as pain intensity, depression and sleep disturbance. Further study of fatigue may be important in understanding its importance in treatment of paediatric chronic pain.
