Young adults report chronic pain at rates of around 12% but lack access to clinical services. There is interest in learning how this emerging adult population engages with and responds to treatment. Using data from young adults aged 18 to 30 years (Mage = 25.8, SD = 3.2), taken from 4 previous randomised controlled trials, the current study investigated the feasibility, acceptability, and efficacy of an internet-delivered psychological pain-management intervention for young adults with chronic pain. ⋯ Findings indicate young adults can engage with and show improvements following a psychological pain-management intervention designed for all adults with chronic pain. Future research is encouraged to examine outcomes related to role functioning of young adults, and moderators of treatment acceptability and efficacy for this population. PERSPECTIVE: Secondary analysis of data from 4 RCTs found an Internet-delivered psychological pain-management intervention acceptable and clinically efficacious for improving disability, anxiety, depression and pain intensity in young adults (18-30) with chronic pain.

Although psychological factors such as anxiety, depression, and pain catastrophizing are known to influence pain outcomes in chronic pain populations, there are mixed results regarding whether they influence experimental pain outcomes in pain-free individuals. The objectives of this study were to determine the associations between psychological factors and experimental pain outcomes in pain-free adolescents and adults. Relationships between anxiety, depression, and pain catastrophizing and experimental pain outcomes across 8 different studies (total N = 595) were examined in different populations of pain-free adult and adolescent participants. ⋯ The overall negative findings suggest that in pain-free individuals, anxiety, depression, and pain catastrophizing are not meaningfully related to experimental pain outcomes. PERSPECTIVE: Psychological variables have been shown to predict pain outcomes in chronic pain populations but these relationships may not generalize to pain-free populations. An analysis of 595 pain-free individuals across 8 studies in our lab revealed that anxiety, depression, and pain catastrophizing were not meaningfully related to experimental pain outcomes.

Chronic low back pain (cLBP) is one of the leading causes of disability globally and represents an enormous burden to aging adults. While numerous factors contribute to cLBP, dysregulation in the hypothalamic-pituitary-adrenal axis and autonomic nervous system functioning have been implicated in its pathogenesis. It is well documented that negative psychological states can modulate biological stress responsivity in chronic pain; however, little is known regarding the influence of positive psychological factors in this relationship. ⋯ Overall, findings highlight the role of psychological risk and resilience factors in modulating physiological stress reactivity. PERSPECTIVE: This article investigated whether psychosocial risk and resilience factors were associated with stress reactivity and recovery in response to laboratory-based pain testing in older adults with chronic low back pain. Results indicate that high resilience factors may be protective by modulating adrenocortical reactivity and recovery profiles.

Review Meta Analysis
Athletes and Experimental Pain: A systematic review and meta-analysis.
The evidence that athletes respond to and report indices of experimental pain differently to non-athlete populations was analysed. Databases screened were SPORTDiscus, PubMED, PsycArticles, the Cochrane Library (Cochrane Database of Systematic Reviews), Web of Science, Scopus, and CINAHL. Studies that compared experimentally induced pain responses (threshold, tolerance, intensity, unpleasantness, bothersomeness, and effect on performance) in athletes and controls were included. ⋯ This study was registered on the PROSPERO site in January 2019 (ref ID: CRD42019119611). PERSPECTIVE: This review examined differences in pain outcomes (threshold, tolerance, intensity, unpleasantness, bothersomeness) and the effect of pain on performance, in athletes versus controls. Meta-analyses revealed athletes had higher threshold and tolerance and found pain less intense than controls; there was some evidence of differences in bothersomeness and performance.

Low back pain (LBP) significantly affects global health, with associated detrimental outcomes such as physical impairment, emotional distress, and exacerbated mental health symptoms. This study evaluated the representation of marginalized groups, including racialized, gender minority, pregnant/lactating, and elderly individuals in randomized controlled trials for pharmacological interventions treating LBP from 2011 to 2020. We searched Embase, MEDLINE, and CINAHL in December 2021, and 139 studies were eligible. ⋯ This review was registered with prospective register of systematic reviews (PROSPERO), ID 296017. PERSPECTIVE: This systematic review investigates patient representation in pharmacological-based clinical trials for low back pain, LBP, the most prevalent pain condition worldwide. Improvements in reporting demographic data and recruiting diverse participant populations-across different racialized, gender and sexual minority, and age groups-will help clinical research generalizability and provide equitable benefits.
