Cognitive-Affective-Behavioral Pathways Linking Adversity and Discrimination to Daily Pain in African-American Adults

Racism and cannabis-related problems among Black adults who smoke cigarettes: The role of negative emotions in responses to experiencing racism

Black Americans who use cannabis appear at greater risk for negative cannabis-related outcomes, and cannabis use is more common among individuals who smoke cigarettes. Race-based health disparities concerning cannabis outcomes indicate a need to identify psycho-socio-cultural factors that may play a role in cannabis use and related problems among Black Americans to inform prevention and treatment efforts. Minority stress-based models posit that stressors such as racism increase negative emotions, which may be associated with using substances such as cannabis to cope with negative emotions. Yet, no known research has directly assessed whether negative emotions experienced in response to racism play a role in cannabis-related behaviors. Participants were 254 (50.2% female) Black Americans who endorsed current cigarette smoking and were aged 18-73 (M = 42.1, SD = 14.1). Participants completed an online survey regarding their experiences with racism, smoking, and cannabis-related behaviors. Negative emotions in response to racism were assessed via the Racial Trauma Scale (RTS). Experiencing more frequent racism was related to greater RTS and cannabis-related problems. When entered simultaneously, frequency of racism was related to more cannabis-related problems via RTS, but not anxiety or depression broadly. Racism was related to more cannabis problems via the sequential effects of RTS and a greater quantity of cannabis used. These data indicate that the experience of negative emotions that occur after experiencing racism may play an important role in cannabis misuse among Black Americans.

Using intensive longitudinal assessment to study mechanisms of the Native American pain inequity among persons experiencing depression and/or anxiety: The role of interpersonal discrimination and stress

Native Americans (NA) experience higher rates of chronic pain than other U.S. racial/ethnic groups. Our research has indicated discrimination and stress play a role in chronic pain onset. However, chronic pain research has mostly relied on retrospective reports that may be impacted by recall bias. The current study was a secondary analysis of data from 208 NA, 206 Black, 202 Latinx, and 206 non-Hispanic White (NHW) participants from an efficacy trial of a mobile health intervention for depression and anxiety. Participants were prompted to complete 6 months of twice daily ecological momentary assessments (EMAs) that included stress and pain. Discrimination was assessed at baseline. Pain EMAs were used to reduce recall bias and estimate chronic pain prevalence. Dynamic structural equation modeling assessed the impact of race/ethnicity and discrimination on stress-pain relationships, as well as pain and stress dynamics. To assess chronic pain (pain ≥3-months), participants had to complete ≥3-months of consecutive EMAs, leaving 578 participants available for primary analyses (there were no racial/ethnic differences in EMA completion). Results showed NAs had the highest rate of chronic pain that was statistically significantly higher than NHW and Black participants. Controlling discrimination eliminated the NA-NHW, but not the NA-Black, pain inequity. Moreover, a reciprocal stress-pain relationship was found and was stronger in NAs than other groups. Discrimination did not exacerbate stress-pain relationships but was associated with higher rates of chronic pain and greater pain fluctuations, regardless of race/ethnicity. These findings indicate that targeting stress and discrimination could help reduce the NA pain inequity. PERSPECTIVE: Native Americans experienced a self-reinforcing stress-pain cycle in which stress predicted future pain and pain predicted future stress. This cycle was stronger than Black, Latinx, and non-Hispanic White groups. Discrimination was associated with chronic pain but not stronger stress-pain relationships. These findings have implications for treatment.

Temporal summation of pain in sickle cell disease: comparison of adolescents and young adults with chronic vs. infrequent pain

OBJECTIVE

This study examined the role of central sensitization in the experience of pain among adolescents and young adults with the most severe genotypes of sickle cell disease (SCD). We hypothesized that adolescents and young adults with chronic SCD pain would demonstrate a higher perceptual response to repeated stimulation of identical intensity (i.e., temporal summation of pain, TSP) compared to counterparts with infrequent pain. We also examined psychological risk factors that can impact pain sensitivity.

METHODS

Patients ages 12-21 years, diagnosed with SCD type Hb SS or Hb S Beta0Thalasemia, who reported infrequent pain (≤2 pain days/month; n = 25) or met AAPT criteria for chronic SCD pain (n = 25) were enrolled. Patients were age- and sex-matched, with similar proportions receiving chronic blood transfusion and hydroxyurea. Patients completed static quantitative sensory testing (QST) and dynamic TSP testing to assess pain sensitivity. Patients and a caregiver completed demographic and psychological measures (depression, anxiety, pain interference, pain catastrophizing).

RESULTS

Simple slope analysis revealed differentially elevated heat TSP among adolescents and young adults with chronic SCD pain (b = 3.14, p = .002) but not those with infrequent pain (b = 0.45, p = .61). Faster habituation was further observed for those with chronic compared to infrequent pain. Adolescents and young adults with chronic pain reported more frequent depression, anxiety, and pain interference symptoms; however, psychological symptoms and pain catastrophizing were not associated with QST or TSP (ps >.17).

CONCLUSION

Current results demonstrate that a well-established, prognostic, QST risk marker (i.e., TSP) may distinguish chronic from infrequent pain subgroups of adolescents and young adults with SCD.

Health Care Discrimination Affects Patient Activation, Communication Self-Efficacy, and Pain for Black Americans

This study examines whether a key psychosocial factor-perceiving racial discrimination in health care-is associated with worse patient activation, communication self-efficacy, and physical health outcomes for Black veterans with chronic pain. Moreover, we explore the role of physician-patient working alliance as a moderator that may alleviate the potential consequences of perceiving racial discrimination. This work is a secondary analysis of baseline data from a clinical trial with 250 U.S. Black veterans with chronic musculoskeletal pain. Participants were recruited from primary care clinics at a Midwestern VA hospital between 2018 and 2021. Perceiving racial discrimination in health care was associated with lower patient activation, lower self-efficacy in communicating with one's physician, higher pain intensity, and lower pain management self-efficacy (ps < .049) but was unrelated to reports of pain interference or use of pain coping strategies (ps > .157). Although the relationship between perceived discrimination and patient activation was moderated by working alliance (P = .014), having a stronger working alliance improved patient activation to varying degrees across levels of perceived discrimination (rather than buffering against negative outcomes when perceiving higher levels of discrimination). Moderation was not significant on any other measures. This study deepens our understanding of the broad range of health outcomes that are (not) associated with perceiving racial discrimination in health care. Contrary to prior theorizing, this work also indicates that having a strong working alliance does not attenuate the consequences of perceiving discrimination among Black individuals living with pain. These results highlight the need for system-level interventions to address perceptions of racial mistreatment in health care. PERSPECTIVE: This work has important public health implications by identifying the broad range of outcomes associated with perceived discrimination in health care among Black Americans. Importantly, a strong physician-patient relationship did not buffer Black individuals from the consequences of perceiving discrimination. These findings inform intervention targets to mitigate racial health disparities.

Chronic Low Back Pain Causal Risk Factors Identified by Mendelian Randomization: a Cross-Sectional Cohort Analysis

Background Context

There are a number of risk factors- from biological, psychological, and social domains- for non-specific chronic low back pain (cLBP). Many cLBP treatments target risk factors on the assumption that the targeted factor is not just associated with cLBP but is also a cause (i.e, a causal risk factor). In most cases this is a strong assumption, primarily due to the possibility of confounding variables. False assumptions about the causal relationships between risk factors and cLBP likely contribute to the generally marginal results from cLBP treatments.

Purpose

The objectives of this study were to a) using rigorous confounding control compare associations between modifiable causal risk factors identified by Mendelian randomization (MR) studies with associations in a cLBP population and b) estimate the association of these risk factors with cLBP outcomes.

Study Design/Setting

Cross sectional analysis of a longitudinal, online, observational study.

Patient Sample

1,376 participants in BACKHOME, a longitudinal observational e-Cohort of U.S. adults with cLBP that is part of the NIH Back Pain Consortium (BACPAC) Research Program.

Outcome Measures

Pain, Enjoyment of Life, and General Activity (PEG) Scale.

Methods

Five risk factors were selected based on evidence from MR randomization studies: sleep disturbance, depression, BMI, alcohol use, and smoking status. Confounders were identified using the ESC-DAG approach, a rigorous method for building directed acyclic graphs based on causal criteria. Strong evidence for confounding was found for age, female sex, education, relationship status, financial strain, anxiety, fear avoidance and catastrophizing. These variables were used to determine the adjustment sets for the primary analysis. Potential confounders with weaker evidence were used for a sensitivity analysis.

Results

Participants had the following characteristics: age 54.9 ± 14.4 years, 67.4% female, 60% never smokers, 29.9% overweight, 39.5% obese, PROMIS sleep disturbance T-score 54.8 ± 8.0, PROMIS depression T-score 52.6 ± 10.1, Fear-avoidance Beliefs Questionnaire 11.6 ± 5.9, Patient Catastrophizing Scale 4.5 ± 2.6, PEG 4.4 ± 2.2. In the adjusted models alcohol use, sleep disturbance, depression, and obesity were associated with PEG, after adjusting for confounding variables identified via a DAG constructed using a rigorous protocol. The adjusted effect estimates- the expected change in the PEG outcome for every standard deviation increase or decrease in the exposure (or category shift for categorical exposures) were the largest for sleep disturbance and obesity. Each SD increase in the PROMIS sleep disturbance T-score resulted in a mean 0.77 (95% CI: 0.66, 0.88) point increase in baseline PEG score. Compared to participants with normal BMI, adjusted mean PEG score was slightly higher by 0.37 points (95% CI: 0.09, 0.65) for overweight participants, about 0.8 to 0.9 points higher for those in obesity classes I and II, and 1.39 (95% CI: 0.98, 1.80) points higher for the most obese participants. Each SD increase in the PROMIS depression T-score was associated with a mean 0.28 (95% CI: 0.17, 0.40) point increase in baseline PEG score, while each SD decrease in number of alcoholic drinks per week resulted in a mean 0.12 (95%CI: 0.01, 0.23) increase in baseline PEG score in the adjusted model.

Conclusions

Several modifiable causal risk factors for cLBP - alcohol use, sleep disturbance, depression, and obesity- are associated with PEG, after adjusting for confounding variables identified via a DAG constructed using a rigorous protocol. Convergence of our findings for sleep disturbance, depression, and obesity with the results from MR studies, which have different designs and biases, strengthens the evidence for causal relationships between these risk factors and cLBP (1). The estimated effect of change in a risk factors on change in PEG were the largest for sleep disturbance and obesity. Future analyses will evaluate these relationships with longitudinal data.

Biobehavioral Predictors of Pain Intensity, Pain Interference, and Chronic Pain Episodes: A Prospective Cohort Study of African-American Adults

Racial disparities in pain experiences are well-established, with African-American (AA) adults reporting higher rates of daily pain, increased pain severity, and greater pain-related interference compared to non-Hispanic Whites. However, the biobehavioral factors that predict the transition to chronic pain among AA adults are not well understood. This prospective cohort study provided a unique opportunity to evaluate predictors of chronic pain onset among 130 AA adults (81 women), ages 18 to 44, who did not report chronic pain at their baseline assessment and subsequently completed follow-up assessments at 6- and 12-months. Outcome measures included pain intensity, pain-related interference, and chronic pain status. Comprehensive assessments of sociodemographic and biobehavioral factors were used to evaluate demographics, socioeconomic status, stress exposure, psychosocial factors, prolonged hypothalamic-pituitary-adrenal secretion, and quantitative sensory testing responses. At baseline, 30 adults (23.1%) reported a history of prior chronic pain. Over the 12-month follow-up period, 13 adults (10.0%) developed a new chronic pain episode, and 18 adults (13.8%) developed a recurrent chronic pain episode. Whereas socioeconomic status measures (ie, annual income, education) predicted changes in pain intensity over the follow-up period, quantitative sensory testing measures (ie, pain threshold, temporal summation of pain) predicted changes in pain interference. A history of chronic pain and higher depressive symptoms at baseline independently predicted the onset of a new chronic pain episode. The present findings highlight distinct subsets of biobehavioral factors that are differentially associated with trajectories of pain intensity, pain-related interference, and onset of chronic pain episodes in AA adults. PERSPECTIVE: This prospective study sought to advance understanding of biobehavioral factors that predicted pain outcomes over a 12-month follow-up period among AA adults without chronic pain at their initial assessment. Findings revealed distinct subsets of factors that were differentially associated with pain intensity, pain-related interference, and onset of chronic pain episodes.

Predictive Model of Anxiety and Depression Perception in Multiple Sclerosis Patients: Possible Implications for Clinical Treatment

Multiple Sclerosis (MS) is a neurodegenerative disease characterized by motor and non-motor symptoms, including emotional distress, anxiety, and depression. These emotional symptoms currently have a pharmacological treatment with limited effectiveness; therefore, it is necessary to delve into their relationship with other psychological, functional, or prefrontal alterations. Additionally, exploring non-pharmacological therapeutic alternatives that have shown benefits in addressing emotional distress in MS patients is essential.

AIM

To establish a predictive model for the presence of anxiety and depression in MS patients, based on variables such as psychological well-being, functional activity, and prefrontal symptoms. Additionally, this study aimed to propose non-pharmacological therapeutic alternatives based on this model.

MATERIALS AND METHODS

A descriptive, observational, and cross-sectional study was conducted with a sample of 64 diagnosed MS patients who underwent functional and cognitive assessments using the following questionnaires and scales: Functional Activities Questionnaire (FAQ), Acceptance and Action Questionnaire (AAQ-II), Experiences Questionnaire (EQ), Self-Compassion Scale Short Form (SCS-SF), Beck Depression Inventory II (BDI-II), State-Trait Anxiety Inventory (STAI), and Prefrontal Symptoms Inventory (PSI).

RESULTS

The model showed an excellent fit to the data and indicated that psychological well-being was the most significant predictor of the criteria (β = -0.83), followed by functional activity (β = -0.18) and prefrontal symptoms (β = 0.15). The latter two are negatively related to psychological well-being (β = -0.16 and β = -0.75, respectively).

CONCLUSIONS

Low psychological well-being is the variable that most significantly predicts the presence of anxiety and depression in MS patients, followed by functional activity and prefrontal alterations. Interventions based on mindfulness and acceptance are recommended, along with nutritional interventions such as antioxidant-enriched ketogenic diets and moderate group physical exercise.

Adversity type and timing predict temporal summation of pain in African-American adults

African Americans are disproportionately exposed to adversity across the lifespan, which includes both stressful and traumatic events. Adversity, in turn, is associated with alterations in pain responsiveness. Racial differences in pain responsiveness among healthy adults are well established. However, the extent to which adversity type and timing are associated with alterations in pain responsiveness among healthy African-American adults is not well understood. The present study included 160 healthy African-American adults (98 women), ages 18 to 45. Outcome measures included pain tolerance and temporal summation of pain to evoked thermal pain. Composite scores were created for early-life adversity (childhood trauma, family adversity) and recent adversity (perceived stress, chronic stress burden). A measure of lifetime racial discrimination was also included. Higher levels of recent adversity were associated with higher temporal summation of pain, controlling for gender, age, and education. Neither early-life adversity nor lifetime racial discrimination were associated with temporal summation of pain. The present findings suggest that heightened temporal summation of pain among healthy African-American adults is associated with exposure to recent adversity events. Improved understanding of how recent adversity contributes to heightened temporal summation of pain in African Americans could help to mitigate racial disparities in pain experiences by identifying at-risk individuals who could benefit from early interventions.
