Battle of the Appraisals: Pain-Related Injustice Versus Catastrophizing as Mediators in the Relationship Between Pain Intensity and 3-Month Outcomes in Adolescents with Chronic Pain

Perceived injustice and pain-related outcomes in children with pain conditions: A systematic review

OBJECTIVE

Research indicates that perceived injustice significantly influences pain-related outcomes and is associated with delayed recovery in adults. This systematic review examines the relationship between perceived injustice and pain-related outcomes in children with pain conditions.

METHODS

A search of published studies in English in PubMed, PsychInfo, and Cochrane Database of Systematic Reviews from database inception through December 2022 were performed. The search criteria focused on studies that measured perceived injustice and pain-related outcomes in children with pain conditions. Out of 56 articles screened, 8 met the inclusion criteria, providing data on 1240 children with pain conditions.

RESULTS

The average age of participants across all studies was 14.12 years (SD = 2.25), with 68.2% being female. There was strong evidence that higher perceived injustice is associated with worse pain intensity, functional disability, mental health outcomes, and emotional, social, and school functioning.

CONCLUSION

The results of this study underscore how perceptions of injustice are associated various pain-related outcomes across different domains of children's lives. The findings highlight the need for screening and treatments targeting injustice appraisals in pediatric populations with pain conditions. The discussion addresses possible determinants and mechanisms of perceived injustice, along with implications for research and clinical practice.

Perceived Injustice and Anger in Fibromyalgia With and Without Comorbid Mental Health Conditions: A Hebrew Validation of the Injustice Experience Questionnaire

OBJECTIVES

Perceived injustice (PI), assessed by the Injustice Experience Questionnaire (IEQ), is an important trigger of anger. Both PI and anger are associated with adverse chronic pain outcomes, and with comorbid mental health severity. We aimed examined the roles of PI and anger in mediating pain across Fibromyalgia patients, with and without comorbid anxiety/depression (FM+A/D, FM-A/D, respectively), as well as rheumatoid arthritis (RA), and pain-free controls (PFC). We hypothesized the highest levels of PI, anger, and pain in FM+A/D patients, followed by FM-A/D, RA, and PFC, thus also validating a Hebrew version of the IEQ.

METHODS

We translated the IEQ using the forward-backward method and collected data online. Based on self-reported anxiety/depression, the sample comprised 66 FM+A/D patients, 64 FM-A/D, 34 RA, and 32 PFCs. Assessments included the IEQ, state and trait anger, pain intensity, anxiety, depression, and pain catastrophizing. The structure and reliability of the Hebrew IEQ were examined using factor analysis and Cronbach alpha. Bootstrapped-based modeling was used to test the roles of state and trait anger in mediating and moderating the relationship between PI and pain intensity.

RESULTS

We confirmed a one-factor structure of the IEQ, with excellent reliability. FM+A/D patients demonstrated the highest scores in all measures. Within this group, trait anger moderated the mediating effect of state anger in the relationship between PI and pain intensity.

DISCUSSION

Our findings validate a Hebrew IEQ and highlight the importance of PI and state and trait anger in the differential manifestation of mental health comorbidity in FM.

Individual Dimensions of Pain Catastrophizing Do Not Mediate the Effect of Sociodemographic and Psychological Factors on Chronic Orofacial Pain Severity, Interference, and Jaw Limitation: A Structural Equation Modeling Approach

Pain catastrophization (PC), involving rumination, magnification, and helplessness, can be viewed as a coping strategy associated with chronic pain. PC is considered a driving force in mediating pain-related outcomes, but it is still unclear whether PC mediates the relationship between psychological and sociodemographic factors with chronic pain when considered in a single model. Using baseline data from a parent study, this study examined the effect of positive and negative psychological and sociodemographic factors on pain severity, interference, and jaw limitation mediated by the PC dimensions in a sample of 397 temporomandibular disorder (TMD) participants using structural equation modeling (SEM). SEM revealed that pain severity regressed on age, sex, education, and income; interference regressed on positive and negative psychological factors, education, and income; and jaw limitation regressed on age. The PC dimensions did not individually mediate these relationships. Although they jointly mediated the relationships between negative psychological factors and pain severity and between age and pain interference, the effect size was small, suggesting that PC is not a critical factor in mediating TMD pain outcomes. Reducing negative cognitions, not just PC, may be of greatest benefit to the most vulnerable TMD populations. PERSPECTIVE: This study examines sociodemographic and psychological factors that affect orofacial pain, finding that the pain catastrophizing dimensions do not mediate these relationships. Understanding which factors most strongly affect pain outcomes will help identify targets for intervention to produce the greatest benefit for the most vulnerable persons suffering from pain.

Effectiveness of music therapy within community hospitals: an EMMPIRE retrospective study

Introduction

Given the challenges health systems face in providing effective nonpharmacologic treatment for pain and psychological distress, clinical effectiveness studies of evidence-based strategies such as music therapy (MT) are needed.

Objectives

This study examined changes in patient-reported outcomes (PROs) after MT and explored variables associated with pain reduction of ≥2 units on a 0 to 10 numeric rating scale (NRS).

Methods

A retrospective review was conducted on initial MT interventions provided to adults receiving community hospital care between January 2017 and July 2020. Sessions were included if participants reported pre-session pain, anxiety, and/or stress scores of ≥4 on the NRS. Data analysis included a bootstrap analysis of single-session changes in PROs and a logistic regression exploring variables associated with pain reduction (ie, ≥2 units vs <2 units).

Results

Patients (n = 1056; mean age: 63.83 years; 76.1% female; 57.1% White; 41.1% Black/African American) reported clinically significant mean reductions in pain (2.04 units), anxiety (2.80 units), and stress (3.48 units). After adjusting for demographic, clinical, and operational characteristics in the model (c-statistic = 0.668), patients receiving an MT session in which pain management was a goal were 4.32 times more likely (95% confidence interval 2.26, 8.66) to report pain reduction of ≥2 units than patients receiving an MT session in which pain management was not a session goal.

Conclusion

This retrospective study supports the clinical effectiveness of MT for symptom management in community hospitals. However, additional research is needed to determine which characteristics of MT interventions and patients influence pain change.

The Experience of BIPOC Living with Chronic Pain in the USA: Biopsychosocial Factors that Underlie Racial Disparities in Pain Outcomes, Comorbidities, Inequities, and Barriers to Treatment

PURPOSE OF REVIEW

This review synthesizes recent findings related to the biopsychosocial processes that underlie racial disparities in chronic pain, while highlighting opportunities for interventions to reduce disparities in pain treatment among BIPOC.

RECENT FINDINGS

Chronic pain is a prevalent and costly public health concern that disproportionately burdens Black, Indigenous, and people of color (BIPOC). This unequal burden arises from an interplay among biological, psychological, and social factors. Social determinants of health (e.g., income, education level, and lack of access or inability to utilize healthcare services) are known to affect overall health, including chronic pain, and disproportionately affect BIPOC communities. This burden is exacerbated by exposure to psychosocial stressors (i.e., perceived injustice, discrimination, and race-based traumatic stress) and can affect biological systems that modulate pain (i.e., inflammation and pain epigenetics). Further, there are racial/ethnic disparities in pain treatment, perpetuating the cycle of undermanaged chronic pain among BIPOC.

Bias in Musculoskeletal Pain Management and Bias-Targeted Interventions to Improve Pain Outcomes: A Scoping Review

Bias in healthcare negatively impacts disparities in care, treatment, and outcomes, especially among minority populations. A scoping review of the literature was performed to provide a deeper understanding of how bias influences musculoskeletal pain and potential effects of bias-targeted interventions on reducing pain disparities, as well as identify gaps and make suggestions for further research in this area. Publications from peer-reviewed journals were searched using the databases PubMed/MEDLINE, PsycINFO, CINAHL, and Scopus, with 18 studies identified. The literature review revealed that clinician-based bias and discrimination worsen pain and disability by reducing access to treatment and increasing patient pain-related injustice, catastrophizing, depression, and perceived stress. In contrast, clinician education and perspective-taking, patient decision tools, and community outreach interventions can help reduce bias and disparities in musculoskeletal pain outcomes. Increasing the diversity of the healthcare workforce should also be a priority. Models of care focused on health equity may provide an ideal framework to reduce bias and provide sustainable improvement in musculoskeletal pain management.
