It is challenging to synthesize findings across studies of pain impact. This study develops a link to estimate the Patient-Reported Outcomes Measurement Information System (PROMIS) global health measure from the 3-item Pain intensity, interference with Enjoyment of life, interference with General activity (PEG) scale. The PROMIS and PEG items were administered to 795 adults (average age = 51; 54% female, 79% White). ⋯ This study makes it possible to estimate the average global physical health for group-level comparisons in research that includes the PEG. PERSPECTIVE: This article describes an empirical link of the PEG to the PROMIS global physical health scale that makes it possible to estimate the average global physical health in studies that include the PEG. This link can facilitate comparisons among studies that have not administered the PEG or the PROMIS global health scale.

Despite a rapid expansion of cannabis use for pain management, how cannabis and prescription opioids are co-used and whether co-use improves analgesia and promotes reduction of opioid use in the daily lives of individuals with chronic pain is poorly understood. Based upon ecological momentary assessment (EMA), the present study examined 1) how pain and use of opioids and/or cannabis in the previous moment is associated with individuals' choice of opioids and/or cannabis in the next moment, 2) the effects of co-use on pain severity and pain relief, and 3) whether daily total opioid consumption differs on days when people only used opioids versus co-used. Adults with chronic pain (N = 46) using both opioids and cannabis who were recruited online completed a 30-day EMA. ⋯ PERSPECTIVE: This article presents the overall patterns and effects of co-using cannabis and prescription opioids among individuals with chronic pain employing ecological momentary assessment. There were conflicting findings on the association between co-use and analgesia. Co-use was not associated with a reduction in daily opioid consumption in this sample.

The experiences of injustice and their impacts on pain among Latinx Americans are overlooked and understudied. Multidimensional and consequential experiences of racialized discrimination are common for Latinx Americans but have not been considered as factors relevant for enhanced pain experience or risk. In this study, we focused on the experiences of Latinx Americans living in Texas by assessing multiple dimensions of racialized discrimination (total lifetime discrimination, racialized exclusion, stigmatization, discrimination in the workplace or school, and racism-related threat and aggression) and a laboratory marker of central sensitization of pain (temporal summation of mechanical pain, MTS). ⋯ PERSPECTIVE: Racialized discrimination is multidimensional. Latinx Texans experience frequent discrimination that is associated with enhanced temporal summation of pain in the laboratory. Results indicate the importance of societal factors in pain processing and may reflect a mechanism of racism-related pre-clinical central sensitization observable before chronic pain onset.

Randomized Controlled Trial
Comparing the effects of thought suppression and focused distraction on pain-related attentional biases in men and women.
Increasing attentional focus away from pain can affect pain experience, suggesting that cognitive strategies that move attentional allocation may be a moderator of pain. In a pre-post-design, the present study examined the effects of 2 cognitive strategies used in pain contexts, thought suppression and focused distraction, on subsequent pain-related attention. Thought suppression was hypothesized to increase pain-related attention, whereas focused distraction was expected to reduce it. ⋯ PERSPECTIVE: Cognitive strategies could help with pain through changing attention allocation. In this study, the effects of the 2 cognitive strategies thought suppression and focused distraction on pain-related attention in men and women were examined. Elucidating mechanisms that lie behind pain strategies that focus on changing attention may help improve treatments.

Observational Study
Profiles of Pain Acceptance and Values-Based Action in the Assessment and Treatment of Chronic Pain.
Pain acceptance and values-based action are relevant to treatment outcomes in those with chronic pain. It is unclear if patterns of responding in these 2 behavioral processes can be used to classify patients into distinct classes at treatment onset and used to predict treatment response. This observational cohort study had 2 distinct goals. ⋯ In the smaller treated sample, participants in the Low AV and Moderate AV class demonstrated improvements across all outcome variables, whereas those in the High AV class did not. These findings support the role of pain acceptance and values-based action in those with chronic pain. PERSPECTIVE: Individuals with chronic pain can be classified with respect to pain acceptance and values-based action and these groups may respond differently to treatment.
