Learn More >Pediatric functional abdominal pain disorders (FAPD) are associated with adverse outcomes including increased somatization (e.g., heightened physiological sensations that include gastroenterological and non-gastroenterological symptoms) and increased functional disability. Caregiver distress and child anxiety are separately associated with the adverse outcomes of pediatric FAPD. However, the cumulative role of caregiver (i.e., stress, anxiety, and depression) and child psychological functioning (anxiety) in relation to adverse outcomes associated with FAPD, and particularly somatization, is unclear. Thus, the present investigation sought to examine the role of caregiver distress and child anxiety in relation to pain-related functioning (i.e., somatization, pain intensity, functional disability) in youth with FAPD. Data were gathered as part of a larger study examining a psychological treatment for youth with FAPD. Participants (ages 9-14) with FAPD completed measures of child anxiety, pain, and pain-related functioning. Caregivers completed a measure of caregiver distress (e.g., stress, anxiety, depressive symptoms). Pearson correlations revealed significant positive associations between child anxiety and child functional disability. Additionally, caregiver anxiety, child anxiety, and child somatization were all significantly and positively correlated with one another. Therefore, we assessed whether child anxiety may potentially mediate the relationship between caregiver anxiety and child somatization in this cross-sectional study. The indirect association between caregiver anxiety and child somatization via child anxiety was not significant. Future research including longitudinal designs to further understand the relationship between caregiver anxiety, child anxiety, and child pain-related functioning, would enhance understanding of how these potentially modifiable psychological factors may impact adverse outcomes of FAPD.

Learn More >Pain-related fear is considered a strong psychological predictor for both chronic pain and disability. The aims of this study were to systematically review and critically appraise the concurrent association and the predictive value of pain-related fear affecting both pain intensity and disability in individuals with chronic musculoskeletal pain (MSK). PubMed, AMED, CINAHL, PsycINFO, PubPsych, and the grey literature were searched from inception to January 2019. Observational studies reporting cross-sectional and longitudinal associations between pain-related fear and pain intensity and/or disability were included. The GRADE criteria judged whether the overall quality and strength of the evidence was high or low in terms of risk of bias, inconsistency, indirectness, imprecision and publication bias. Seventy observational studies (97% cross-sectional) were included with a total sample of 15,623 individuals (63.56% females) with chronic MSK. Pain-related fear is composed of fear of pain, pain-related anxiety, and fear-avoidance beliefs. Greater levels of fear of pain, pain-related anxiety, and fear-avoidance beliefs were significantly associated with greater pain intensity and disability. However, the quality and strength of the evidence was very low owing to the imprecision of results, risk of bias, indirectness, and publication bias were common across the included studies. Despite these limitations, these findings highlight the potential role that pain-related fear may play in chronic MSK and disability. The field would benefit from research using higher quality studies and longitudinal designs. PERSPECTIVE: This article presents promising results about the concurrent association between pain-related fear and both pain intensity and disability in individuals with chronic MSK. Nevertheless, the overall quality and strength of the evidence was very low in terms of risk of bias, indirectness, imprecision, and publication bias. Thus, the findings should be taken with caution, and further research is needed. PROSPERO: CRD42018082018.
Learn More >Human beings have long consumed opiates and opioids for pleasure and as a treatment for numerous ailments, most notably pain. North America is currently in the grips of a crisis of opioid-related overdoses, and stigma is considered a major driver of the harms. While it is well established that substance use in general is highly stigmatized, stigma is a complex concept and opioid-related stigma is not well understood. A lack of clarity on opioid-related stigma has practice and policy implications in terms of understanding the sources of opioid stigma, how it manifests in various contexts, its impact on affected groups, and the development of effective strategies to redress it.
Learn More >Stress and pain are interleaved at multiple levels – interacting and influencing each other. Both are modulated by psychosocial factors including fears, beliefs, and goals, and are served by overlapping neural substrates. One major contributing factor in the development and maintenance of chronic pain is threat learning, with pain as an emotionally-salient threat – or stressor. Here, we argue that threat learning is a central mechanism and contributor, mediating the relationship between stress and chronic pain. We review the state of the art on (mal)adaptive learning in chronic pain, and on effects of stress and particularly cortisol on learning. We then provide a theoretical integration of how stress may affect chronic pain through its effect on threat learning. Prolonged stress, as may be experienced by patients with chronic pain, and its resulting changes in key brain networks modulating stress responses and threat learning, may further exacerbate these impairing effects on threat learning. We provide testable hypotheses and suggestions for how this integration may guide future research and clinical approaches in chronic pain.

Learn More >Chronic back pain is a major global health problem, while its treatment is hampered by a lack of efficacy and restricted safety profile of common front-line therapies. The present trial aims to determine whether a 3-week open-label placebo treatment reduces pain intensity, and subjective and objective functional disability in chronic back pain patients. This randomized controlled trial, following a pretest-posttest design, enrolled 127 chronic back pain patients (pain duration > 12 weeks) from the Back Pain Center, Neurology, University Hospital Essen, Germany. Patients randomized to the open-label placebo group received a 3-week open-label placebo treatment. Patients in the treatment as usual group received no intervention. Both groups continued treatment as usual. Primary outcome was the change in pain intensity. Secondary outcomes included patient-reported functional disability, objective measures of spine mobility and depression, anxiety and stress. 122 chronic back pain patients were randomized to the open-label placebo group (N=63) or treatment as usual group (N=59). Open-label placebo application led to a larger reduction of pain intensity (-0.62±0.23 vs. 0.11±0.17, all M ± SE, p=.001, d=-0.44) as well as patient-reported functional disability (3.21±1.59 vs. 0.65±1.15, p=.020, d=-0.45) and depression scores (-1.07±0.55 vs. 0.37±0.39, p=.010, d=-0.50) compared to treatment as usual only. OLP treatment did not affect objective mobility parameters, anxiety and stress. Our study demonstrates that a 3-week open-label placebo treatment is safe, well tolerated and reduces pain, disability and depressive symptoms in chronic back pain.

Learn More >Chronic musculoskeletal pain in adolescence is a significant public health concern with 3-5% of adolescents suffering from significant pain-related disability. Pain-related fear and avoidance of activities has been found to have a significant influence on pain outcomes in children and adolescents and is a risk factor for less favorable response to treatment. To address this need, we developed graded exposure treatment for youth with chronic pain (GET Living). We describe the rationale, design, and implementation of a two-group randomized controlled trial (RCT) enhanced with single-case experimental design (SCED) methodology with a sample of 74 adolescents with chronic musculosketal pain and their parent caregivers. GET Living includes education, behavioral exposures, and parent intervention jointly delivered by pain psychology and physical therapy providers. The multidisciplinary pain management control group includes pain psychology delivered education and pain self-management skills training (e.g., relaxation, cognitive skills) and separate physical therapy. Assessments include brief daily diaries (baseline to discharge, 7-days at 3-month and 6-month follow-up), comprehensive in-person evaluations at baseline and discharge, and questionnaire across all time points (baseline, discharge, 3-month and 6-month follow-up). Primary outcome is pain-related fear avoidance. Secondary outcome is functional disability. We also outline all additional outcomes, exploratory outcomes, covariates, and implementation measures. The objective is to offer a mechanism-based, targeted intervention to youth with musculoskeletal pain to enhance likelihood of return to function.
