The current cross-sectional study investigates whether pain catastrophizing mediates the relationship between ethnicity/race and pain, disability and physical function in individuals with knee osteoarthritis. Furthermore, this study examined mediation at 2-year follow-up. Participants included 187 community-dwelling adults with unilateral or bilateral knee pain who screened positive for knee osteoarthritis. ⋯ The findings are discussed in light of structural/systemic factors that may contribute to greater self-reports of pain catastrophizing among NHB individuals. PERSPECTIVE: The current study examines whether pain catastrophizing mediates the relationship between ethnicity/race and OA-related pain, disability, and functional impairment at baseline and during a 2-year follow-up period in non-Hispanic Black and non-Hispanic White adults with knee pain. These results point to the need for interventions that target pain catastrophizing.

Native Americans (NAs) experience higher rates of chronic pain than the general U. S. population, but the risk factors for this pain disparity are unknown. NAs also experience high rates of stressors and cardiovascular and metabolic health disparities (eg, diabetes, cardiovascular disease) consistent with allostatic load (stress-related wear-and-tear on homeostatic systems). ⋯ This suggests cardiometabolic allostatic load may promote spinal sensitization in healthy NAs, that is not concomitant with pain sensitization, perhaps representing a unique pain risk phenotype in NAs. PERSPECTIVE: Healthy, pain-free Native Americans experienced greater cardiometabolic allostatic load that was associated with a pronociceptive pain phenotype indicative of latent spinal sensitization (ie, spinal sensitization not associated with hyperalgesia). This latent spinal sensitization could represent a pain risk phenotype for this population.

Review Meta Analysis
The prevalence, characteristics and impact of chronic pain in people with muscular dystrophies: A systematic review and meta-analysis.
Chronic pain is a frequent, yet under-recognized and under-assessed problem in people with muscular dystrophies (MDs). Knowledge of the prevalence and characteristics of chronic pain, and its impact on function and quality of life is limited and lacks systematic exploration. This article aims to systematically review and synthesize existing literature that addresses chronic pain prevalence, characteristics and impact in people with different types of MDs. ⋯ The protocol for this review has been published on PROSPERO (CRD42020168096). PERSPECTIVES: This is the first systematic review and meta-analysis exploring the prevalence, and nature and impact of chronic pain in people with MDs. The present study demonstrates how common chronic pain is across various MD populations and highlights the need for better recognition and understanding of the nature and impact of pain from health professionals.

Review Meta Analysis
Efficacy of online-based Acceptance and Commitment Therapy for chronic pain: A systematic review and meta-analysis.
Acceptance and Commitment Therapy (ACT) has been widely tested for chronic pain, with demonstrated efficacy. Nevertheless, although there is meta-analytical evidence on the efficacy of face-to-face ACT, no reviews have been performed on online ACT in this population. The aim of this meta-analysis is to determine the efficacy of online ACT for adults with chronic pain, when compared with controls. ⋯ PERSPECTIVE: This is the first meta-analytical review on the efficacy of online ACT for people with chronic pain. It comprises 5 RCTs that compared online ACT with active and/or inactive controls. Online ACT was more efficacious than controls regarding pain interference, pain intensity, depression, anxiety, mindfulness, and psychological flexibility.

Randomized Controlled Trial
The Effect of Literacy-Adapted Psychosocial Treatments on Biomedical and Biopsychosocial Pain Conceptualization.
This is a secondary data analysis of a subgroup of participants who received the Learning About My Pain (LAMP) intervention (clinicaltrials.gov identifier NCT01967342). We examined the effects of LAMP on pre-to-post changes in biomedical and biopsychosocial pain conceptualization and whether those changes in pain conceptualization were associated with physical and psychological functioning. Participants were randomized into three conditions: Cognitive Behavioral Therapy (CBT), Pain Psychoeducation (EDU), or Usual Medical Care (UC). ⋯ Overall, results of this study suggest the need for targeting specific pain beliefs that influence pain-related outcomes. PERSPECTIVE: This article presents the potential benefits of providing literacy-adapted psychosocial treatments to expand pain conceptualization beyond a biomedical-only understanding and toward a biopsychosocial conceptualization of the experience of pain. Furthermore, the association of changes in pain conceptualization and pain-related functioning argues for its potential clinical relevance.
