Exercise and Dietary Recommendations for Women with Chronic Pain: What's Weight and Race Got To Do with It?

Exercise and diet are beneficial for pain, yet many patients do not receive such recommendations from providers. This may be due to biases related to gender, race, and weight. We recruited medical students (N = 90) to view videos of women with chronic back pain performing a functional task; patients varied by weight (overweight/obese) and race (Black/White). For each woman patient, providers rated their likelihood of recommending exercises or dietary changes. Ratings significantly differed across recommendations (F(2.75, 244.72) = 6.19, P < .01) in that providers were more likely to recommend flexibility exercises than aerobic exercises and dietary changes and were more likely to recommend strength exercises than dietary changes. Results also indicated that women with obesity were more likely to receive aerobic (F(1,89) = 17.20, P < .01), strength (F(1,89) = 6.08, P = .02), and dietary recommendations (F(1,89) = 37.56, P < .01) than were women with overweight. Additionally, White women were more likely to receive a recommendation for flexibility exercises (F(1,89) = 4.92, P = .03) than Black women. Collectively, these findings suggest that providers' exercise and dietary recommendations for women with chronic pain are influenced by the weight status and racial identity of the patient. Future studies are needed to identify the reasons underlying these systematic differences, including the stereotypes and attitudes that may be driving these effects. PERSPECTIVE: This article presents results on how patient weight and race impact providers' exercise and diet recommendations for women with chronic back pain. Provider recommendations for these modalities may be systematically biased in a way that impedes care and impacts patient functioning.

The Pain and PRAYER Scale (PPRAYERS): development and validation of a scale to measure pain-related prayer.

OBJECTIVES: Prayer is a devotional practice used across religious traditions to commune with the sacred and has been used as a coping strategy for pain. Previous research on prayer as a pain coping strategy has had mixed results, with prayer associated with both greater and lesser pain depending on prayer type. To date, there has been only 1 measure of pain-related prayer, the prayer subscale of the Coping Strategies Questionnaire-Revised, which measures solely passive prayer, neglecting other types of prayer (eg, active and neutral). To better understand the relationship between pain and prayer, a comprehensive measure of prayer for pain is needed. The aim of this study was to develop and validate the Pain-related PRAYER Scale (PPRAYERS), a questionnaire exploring active, passive, and neutral petitionary prayers to God or a higher power in response to pain. METHODS: Adults with chronic pain (n = 411) completed demographic, health, and pain-related questionnaires, including PPRAYERS. RESULTS: Results of an exploratory factor analysis yielded a 3-factor structure consistent with active, passive, and neutral subscales. A confirmatory factor analysis resulted in adequate fit after the removal of 5 items. PPRAYERS showed good internal consistency and convergent and discriminant validity. DISCUSSION: These results provide preliminary validation for PPRAYERS, a novel measure for pain-related prayer.

Concurrent and longitudinal associations among insomnia symptoms, internalizing problems, and chronic pain in youth.

OBJECTIVE: Although insomnia symptoms and chronic pain are associated, less is known about the temporal nature of the associations between these variables or the impact of internalizing symptoms on the associations. Concurrent and longitudinal associations were examined among insomnia symptoms, internalizing symptoms, and pain in youth with chronic pain in this retrospective analysis of clinical records. We hypothesized the following: (a) pain, insomnia symptoms, and internalizing symptoms would be significantly interrelated at all waves, (b) insomnia symptoms would more strongly predict future pain than the reverse, and (c) internalizing symptoms would mediate the longitudinal association between insomnia symptoms and pain. METHOD: Youth (N = 132; age M = 15.34 years, SD = 1.86 years) were assessed at their initial and two subsequent appointments (time between appointments M = 6.48 months, SD = 4.43 months). At each appointment, youth reported their pain severity, insomnia symptoms, and internalizing symptoms. Confirmatory factor analyses (CFAs) and cross-lagged panel models using structural equation modeling were conducted. CFAs and the cross-lagged panel model with pain and insomnia symptoms as latent constructs converged. RESULTS: Pain and insomnia symptoms were positively correlated within each wave. We found bidirectional longitudinal associations between insomnia symptoms and pain. CONCLUSIONS: Overall, these data demonstrate a bidirectional relationship between insomnia symptoms and pain, as well as weak support for internalizing symptoms mediating the association between pain and insomnia symptoms. Treatment of youth with chronic pain should prioritize concurrent or early treatment of comorbid insomnia symptoms to maximize response to pain treatment.

The impact of maternal child- and self-oriented pain-related injustice appraisals upon maternal attention to child pain, attention to anger, and pain-attending behavior.

Objectives: The current study investigated the role of maternal child- and self-oriented injustice appraisals about child pain in understanding maternal attention for child pain and adult anger cues and pain-attending behavior. Methods: Forty-four children underwent a painful cold pressor task (CPT) while their mother observed. Eye tracking was used to measure maternal attention to child pain and adult anger cues. Initial attention allocation and attentional maintenance were indexed by probability of first fixation and gaze duration, respectively. Maternal pain-attending behaviors toward the child were videotaped and coded after CPT completion. Mothers also rated the intensity of pain and anger cues used in the free-viewing tasks. All analyses controlled for maternal catastrophizing about child pain. Results: Neither child-oriented nor self-oriented injustice was associated with maternal attentional bias toward child pain. Regarding attention toward self-relevant anger cues, differential associations were observed for self- and child-oriented injustice appraisals, with maternal self-oriented injustice being associated with a greater probability of first fixating on anger and with higher anger ratings, whereas maternal child-oriented injustice was associated with enhanced attentional maintenance toward anger. Neither type of maternal injustice appraisals was associated with maternal pain-attending behavior, which was only associated with maternal catastrophizing. Conclusions: The current study sheds light on potential differential mechanisms through which maternal self- vs. child-oriented injustice appraisals may exert their impact on parent and child pain-related outcomes. Theoretical implications and future directions are discussed.

The influence of perceived racial bias and health-related stigma on quality of life among children with sickle cell disease.

Objectives: Individuals with sickle cell disease (SCD) experience significant health problems that may result in unpredictable pain episodes and frequent healthcare utilization. Disparities in clinical care may contribute to health-related stigma and racial bias for this majority African-American/Black population. There is less known about the influence of health-related stigma and racial bias on the health-related quality of life (HRQOL) of children with SCD. In the present study, we assessed these relationships and identified differences across demographic factors (i.e. age, gender).Design: Data was collected from African American children with SCD aged 8-16 years (57% male, 63% HbSS). Children completed the Childhood Stigma Scale (adapted for SCD), the Child Perceptions of Racism in Children and Youth scale, and the Pediatric Quality of Life Inventory Sickle Cell Disease Module. Caregivers provided demographic information.Results: In the first regression model, health-related stigma (p = .007) predicted HRQOL, but neither age nor gender were significant predictors. In the second regression model, age (p = .03) predicted HRQOL, but neither gender nor racial bias were significant predictors. Of interest, there was a significant interaction between age, gender, and racial bias (p = .02). Specifically, older girls who reported high levels of perceived racial bias had poorer HRQOL.Conclusions: Our study highlights the need for increased awareness about the effects of health-related stigma and racial bias on HRQOL for children with SCD, particularly for older girls who endorse racial bias. Our findings will guide future stigma and bias reduction interventions that may meet the needs of older girls with SCD.

Anger as a Mechanism of Injustice Appraisals in Pediatric Chronic Pain.

Mechanisms explaining the relationship between pain-related injustice appraisals and functional outcomes in youth with chronic pain have yet to be examined. In studies of adults, greater pain-related injustice is associated with worse depressive symptoms and greater pain through greater anger. No study to date has examined anger expression as a mediator in the relationships between pain-related injustice appraisals and physical and psychosocial functioning in youth with chronic pain. The current sample consisted of 385 youth with varied pain conditions (75% female, 88% White, Mage=14.4 years) presenting to a university-affiliated pain clinic. Patients completed self-report measures assessing anger expression (anger-out and anger-in), pain-related injustice, pain intensity, functional disability, and emotional, social, and school functioning. Bootstrapped mediation analyses indicated that only anger-out (indirect effect= -.12, 95% CI: -.21, -.05) mediated the relationship between pain-related injustice and emotional functioning, whereas both anger-out (indirect effect= -.17, 95% CI: -.27, -.09) and anger-in (indirect effect= -.13, 95% CI: -.09, -.001) mediated the relationship between pain-related injustice and social functioning. Neither mode of anger expression mediated the relationship between pain-related injustice and pain intensity, functional disability, or school functioning. Collectively, these findings implicate anger as one mechanism by which pain-related injustice impacts psychosocial outcomes for youth with chronic pain. PERSPECTIVE: Anger expression plays a mediating role in the relationship between pain-related injustice appraisals and psychosocial outcomes for youth with chronic pain. Anger represents one target for clinical care to decrease the deleterious impact of pain-related injustice on emotional and social functioning.

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.

Pain appraisals are closely tied to pain and functional outcomes. Pain-related injustice and pain catastrophizing appraisals have both been identified as important cognitive-emotional factors in the pain experience of youth. Although pain-related injustice and catastrophizing have been linked to worse pain outcomes - as primary predictors and intermediary variables - little is known about whether they operate as independent or parallel mediators of the relationship between pain and functioning in youth. We tested pain-related injustice and catastrophizing appraisals as candidate mediators of the relationship between baseline pain intensity and 3-month functional outcomes in adolescents. Youth with chronic pain (N = 89, 76% female, 89% White, average age = 15 years) completed measures assessing pain intensity, pain-related injustice, and catastrophizing at baseline, as well as measures assessing functional disability and overall quality of life 3 months later. Multiple mediation analyses indicated that injustice mediated the relationship between pain intensity and 3 month quality of life. Exploratory analyses of specific quality of life domains indicated that injustice mediated the relationship between pain intensity and 3 month emotional functioning, whereas catastrophizing mediated the relationship between pain intensity and 3 month social functioning. The findings suggest these pain-related appraisals play different intermediary roles in the relationships among pain and future psychosocial outcomes. PERSPECTIVE: Pain-related injustice and catastrophizing appraisals play different intermediary roles in the relationships among pain and future psychosocial outcomes in youth with chronic pain. Treatments targeting pain-related injustice appraisals in pediatric populations are needed to complement existing treatments for catastrophizing.

Cross-Sectional Associations among Components of Injustice Appraisals and Functioning in Adolescents With Chronic Pain.

OBJECTIVE: Pain-related appraisals, including pain-related injustice, impact the development and maintenance of chronic pain. This cross-sectional study aimed to examine the relationship between the cognitive-emotional components of pain-related injustice-blame/unfairness and severity/irreparability of loss-and functioning in a mixed sample of adolescents with chronic pain. METHODS: Pediatric patients age 11-18 years (N = 408) completed forms assessing pain-related injustice, pain intensity, and physical and psychosocial functioning as part of their routine assessment in a pediatric chronic pain clinic between January 2014 and January 2019. A series of hierarchical regressions were used to evaluate the relationships among the separate components of pain-related injustice appraisals and functioning. RESULTS: Pain intensity and blame/unfairness appraisals were significantly associated with emotional functioning with blame/unfairness being the stronger association (ß = -.27). Blame/unfairness appraisals, severity/irreparability appraisals, and pain intensity were significantly associated with physical functioning with pain intensity being the strongest association (ß = .36). Pain intensity, blame/unfairness appraisals, and severity/irreparability appraisals were significantly associated with social functioning with blame/unfairness being the strongest association (ß = -.34). Pain intensity and severity/irreparability appraisals were significantly associated with school functioning with severity/irreparability being the stronger association (ß = -.19). CONCLUSIONS: These results lend further support to incorporating pain-related injustice appraisals in standard clinical pain assessments. Treatment practices should target the specific injustice appraisals and domains of functioning impacted for each pediatric patient with chronic pain.

Opioid-related risk perceptions in chronic pain: influence of patient gender and previous misuse behaviors.

ABSTRACT: Little is known about the factors that influence providers' perceptions of patient risk for aberrant opioid use. Patient gender may interact with previous opioid misuse to influence these perceptions. We asked 131 physicians to view videos and vignettes for 8 virtual patients with chronic pain. Gender (male/female) and previous prescription opioid misuse (present/absent) varied across patients; the vignettes were otherwise balanced on demographic and clinical characteristics. For each patient, providers assessed 4 risk domains: opioid-related adverse events, opioid misuse or abuse, opioid addiction, and opioid diversion. Results indicated a significant gender-by-misuse interaction for risk of opioid misuse orabuse. When previous misuse behaviors were absent, providers rated men at higher risk; there was no gender difference when previous misuse behaviors were present. A significant gender-by-misuse interaction was found for risk of opioid-related adverse events. Providers perceived men to be at higher risk when previous misuse behaviors were absent; there was no gender difference when previous misuse behaviors were present. A significant gender-by-misuse interaction was found for risk of opioid addiction. Providers rated women at higher risk when previous misuse behaviors were present and men at higher risk when previous misuse behaviors were absent. There were significant main effects of gender and misuse for risk of opioid diversion. Providers rated men and those with previous misuse behaviors at higher risk. These results demonstrate that patient gender and previous opioid misuse have unique and interactive effects on provider perceptions of prescription opioid-related risks. Studies are needed to identify the mechanisms underlying these effects, such as gender-based stereotypes about risk-taking and drug abuse.

Pain-Related Injustice Appraisals in Youth with Sickle Cell Disease: A Preliminary Investigation.

OBJECTIVES: Sickle cell disease (SCD) is a genetic disorder that affects approximately 100,000 Americans, the majority of whom are African American. SCD-related pain often has deleterious effects on functioning and quality of life. The inherited nature of SCD, SCD-related stigma, and serious physical and functional impact of SCD-related pain create a situation ripe for individuals to appraise their SCD-related pain as unfair or unjust. The aim of this preliminary investigation is to explore the extent to which pediatric patients with SCD appraise their pain as unjust and how these appraisals relate to functioning. METHODS: Participants were youth with SCD (N = 30, mean age = 11.3, 57% boys) who attended a hematology clinic visit. Patients were invited to complete paper-based questionnaires assessing pain-related injustice appraisals, pain catastrophizing, pain and hurt, functional disability, depression, anxiety, and peer relationships. RESULTS: Results of hierarchical regressions indicate that pain-related injustice significantly predicted functional disability, depression, and anxiety after controlling for patient pain and catastrophizing. CONCLUSIONS: These findings suggest that pain-related injustice appraisals are an important contributor to the pain experience of youth with SCD. Early identification and remediation of pain-related injustice appraisals could have long-term functional benefits for youth with SCD.

Patient race and opioid misuse history influence provider risk perceptions for future opioid-related problems.

In response to the dual public health crises of chronic pain and opioid use, providers have become more vigilant about assessing patients for risk of opioid-related problems. Little is known about how providers are making these risk assessments. Given previous studies indicating that Black patients are at increased risk for suboptimal pain care, which may be related to stereotypes about drug abuse, the current study examined how patient race and previous opioid misuse behaviors impact providers' risk assessments for future prescription opioid-related problems. Physician residents and fellows (N = 135) viewed videos and read vignettes about 8 virtual patients with chronic pain who varied by race (Black/White) and history of prescription opioid misuse (absent/present). Providers rated patients' risk for future prescription opioid-related adverse events, misuse/abuse, addiction, and diversion, and also completed measures of implicit racial attitudes and explicit beliefs about race differences in pain. Two significant interactions emerged indicating that Black patients were perceived to be at greater risk for future adverse events (when previous misuse was absent) and diversion (when previous misuse was present). Significant main effects indicated that Black patients and patients with previous misuse were perceived to be at greater risk for future misuse/abuse of prescription opioids, and that patients with previous misuse were perceived to be at greater risk of addiction. These findings suggest that racial minorities and patients with a history of prescription opioid misuse are particularly vulnerable to any unintended consequences of efforts to stem the dual public health crises of chronic pain and opioid use.

The Unique and Interactive Effects of Patient Race, Patient Socioeconomic Status, and Provider Attitudes on Chronic Pain Care Decisions.

BACKGROUND: Compared to White and high socioeconomic status (SES) patients, Black and low SES patients receive less adequate pain care. Providers may contribute to these disparities by making biased decisions that are driven, in part, by their attitudes about race and SES. PURPOSE: We examined the effects of patient race and SES on providers' chronic pain decisions and the extent to which providers' implicit and explicit attitudes about race and SES were related to these decisions. METHODS: Physician residents/fellows (n = 436) made pain care decisions for 12 computer-simulated patients with chronic back pain that varied by race (Black/White) and SES (low/high). Physicians also completed measures assessing implicit and explicit attitudes about race and SES. RESULTS: There were three significant race-by-SES interactions: (a) For high SES patients, Black (vs. White) patients were rated as having more pain interference; the opposite race difference emerged for low SES patients. (b) For high SES patients, Black (vs. White) patients were rated as being in greater distress; no race difference emerged for low SES patients. (c) For low SES patients, White (vs. Black) patients were more likely to be recommended workplace accommodations; no race difference emerged for high SES patients. Additionally, providers were more likely to recommend opioids to Black (vs. White) and low (vs. high) SES patients, and were more likely to use opioid contracts with low (vs. high) SES patients. Providers' implicit and explicit attitudes predicted some, but not all, of their pain-related ratings. CONCLUSION: These results highlight the need to further examine the effects of patient race and SES simultaneously in the context of pain care.

Intergroup anxiety in pain care: impact on treatment recommendations made by white providers for black patients.

Race disparities in pain care are well-documented. Given that most black patients are treated by white providers, patient-provider racial discordance is one hypothesized contributor to these disparities. Research and theory suggest that providers' trait-level intergroup anxiety impacts their state-level comfort while treating patients, which, in turn, impacts their pain treatment decisions. To test these hypothesized relationships, we conducted a planned secondary analysis of data from a randomized controlled trial of a perspective-taking intervention to reduce pain treatment disparities. Mediation analyses were conducted on treatment decision data from white providers for black virtual patients with chronic pain. Results indicated that white providers with higher trait-level intergroup anxiety reported lower state-level comfort treating black patients and were thereby more likely to recommend opioid (indirect effect = 0.76, 95% confidence interval [CI]: 0.21-1.51) and pain specialty (indirect effect = 0.91, 95% CI: 0.26-1.78) treatments and less likely to recommend nonopioid analgesics (indirect effect = -0.45, 95% CI: -0.94 to -0.12). Neither trait-level intergroup anxiety nor state-level comfort significantly influenced provider decisions for physical therapy. This study provides important new information about intrapersonal and interpersonal contributors to race disparities in chronic pain care. These findings suggest that intergroup anxiety and the resulting situational discomfort encroach on the clinical decision-making process by influencing white providers' decisions about which pain treatments to recommend to black patients. Should these findings be replicated in future studies, they would support interventions to help providers become more aware of their trait-level intergroup anxiety and manage their state-level reactions to patients who are racially/ethnically different from themselves.

Assessment and Treatment Recommendations for Pediatric Pain: The Influence of Patient Race, Patient Gender, and Provider Pain-Related Attitudes.

Previous studies have documented that racial minorities and women receive poorer pain care than their demographic counterparts. Providers contribute to these disparities when their pain-related decision-making systematically varies across patient groups. Less is known about racial and gender disparities in children with pain or the extent to which providers contribute to these disparities. In a sample of 129 medical students (henceforth referred to as "providers"), Virtual Human methodology and a pain-related version of the Implicit Association Test (IAT) were used to examine the effects of patient race/gender on providers' pain assessment/treatment decisions for pediatric chronic abdominal pain, as well as the moderating role of provider implicit pain-related race/gender attitudes. Findings indicated that providers rated Black patients as more distressed (mean difference [MD] = 2.33, P < .01, standard error [SE] = .71, 95% confidence interval [CI] = .92, 3.73) and as experiencing more pain-related interference (MD = 3.14, P < .01, SE = .76, 95% CI = 1.63, 4.64) compared to White patients. Providers were more likely to recommend opioids for Black patients than White patients (MD = 2.41, P < .01, SE = .58, 95% CI = 1.05, 3.76). Female patients were perceived to be more distressed by their pain (MD = 2.14, P < .01, SE = .79, 95% CI = .58, 3.70) than male patients, however there were no gender differences in treatment recommendations. IAT results indicated that providers held implicit attitudes that Black Americans (M = .19, standard deviation [SD] = .29) and males (M = .38, SD = .29) were more pain-tolerant than their demographic counterparts; however, these implicit attitudes did not significantly moderate their pain assessment/treatment decisions. Future studies are needed to elucidate specific paths through which the pain experience and care of children differ across racial and gender groups. PERSPECTIVE: Providers' pain assessment (ie, pain distress/pain interference) and treatment (ie, opioids) of pediatric pain differs across patient race and to a lesser extent, patient gender. This study represents a critical step in research on pain-related disparities in pediatric pain.

Pain Intensity And Attribution Mediate The Impact Of Patient Weight And Gender On Activity Recommendations For Chronic Pain.

BACKGROUND AND PURPOSE: Despite the notable benefits of physical activity for chronic pain, a large proportion of patients with chronic pain report that they do not receive activity-related recommendations from their providers. Research suggests that patient factors such as weight and gender influence activity-related recommendations for chronic pain. Research also suggests that appraisals of the intensity and cause of pain may explain these weight and gender effects. We investigated the influence of patient weight and gender on observers' likelihood of recommending activity-related treatments for pain. We also explored the mediating effects of observers' ratings of pain severity and the extent to which pain was due to medical and lifestyle factors (pain attribution). PATIENTS AND METHODS: Healthy young adults (N=616; 76% female) viewed videos (Ghent Pain Videos of Daily Activities) and vignettes of 4 patients with chronic back pain performing a standardized functional task. Patients varied by gender (female, male) and weight (normal, obese), but were otherwise equivalent on demographic characteristics and pain behaviors. Participants rated how much pain they perceived the patients to be experiencing, the extent to which they attributed the pain to medical and lifestyle factors, and their likelihood of recommending exercise, physical therapy (PT), and rest. RESULTS: Patient weight and gender significantly interacted to influence exercise, PT, and rest recommendations. Both pain intensity and pain attribution mediated the relationships between patient weight and activity recommendations; however, these mediation effects differed across gender and recommendation type. CONCLUSION: Patient weight and gender influenced laypeople's activity recommendations for chronic pain. Moreover, the results suggest that observers' perceptions of pain intensity and pain attributions are mechanisms underlying these effects. If these findings are replicated in providers, interventions may need to be developed to reduce provider biases and increase their recognition of the benefits of physical activity for chronic pain.

A randomized controlled trial testing a virtual perspective-taking intervention to reduce race and socioeconomic status disparities in pain care.

We conducted a randomized controlled trial of an individually tailored, virtual perspective-taking intervention to reduce race and socioeconomic status (SES) disparities in providers' pain treatment decisions. Physician residents and fellows (n = 436) were recruited from across the United States for this two-part online study. Providers first completed a bias assessment task in which they made treatment decisions for virtual patients with chronic pain who varied by race (black/white) and SES (low/high). Providers who demonstrated a treatment bias were randomized to the intervention or control group. The intervention consisted of personalized feedback about their bias, real-time dynamic interactions with virtual patients, and videos depicting how pain impacts the patients' lives. Treatment bias was re-assessed 1 week later. Compared with the control group, providers who received the tailored intervention had 85% lower odds of demonstrating a treatment bias against black patients and 76% lower odds of demonstrating a treatment bias against low SES patients at follow-up. Providers who received the intervention for racial bias also showed increased compassion for patients compared with providers in the control condition. Group differences did not emerge for provider comfort in treating patients. Results suggest an online intervention that is tailored to providers according to their individual treatment biases, delivers feedback about these biases, and provides opportunities for increased contact with black and low SES patients, can produce substantial changes in providers' treatment decisions, resulting in more equitable pain care. Future studies should examine how these effects translate to real-world patient care and the optimal timing/dose of the intervention.

Impairment of Inhibition of Trigeminal Nociception via Conditioned Pain Modulation in Persons with Migraine Headaches.

OBJECTIVE: To assess conditioned pain modulation efficiency in persons with and without migraine headaches. DESIGN: Cross-sectional assessment of experimental pain. SETTING: University campus and surrounding community in a large Midwestern US city. SUBJECTS: Twenty-three adults with and 32 without a history of migraine headaches participated in the study. Participants were mostly female (N = 40) with an average age of 23 years. METHODS: Four electrocutaneous stimulations of the supraorbital branch of the left trigeminal nerve were delivered at 150% of an individually determined pain threshold. Conditioned pain modulation was assessed by applying a noxious counterstimulus (forearm ischemia) and delivering four more electrocutaneous stimulations. After each stimulation, pain and the nociceptive blink reflex were assessed. Depression and pain catastrophizing were assessed to control for the potential influence of these variables on pain modulation. RESULTS: Participants with and without migraine headaches had similar baseline pain responsivity, without significant differences in pain report or nociceptive blink reflexes. Pain report was inhibited by conditioned pain modulation in both the migraine and control groups. However, unlike nonmigraine controls, participants with migraines did not exhibit an inhibition of nociceptive blink reflexes during the ischemia task. This pattern persisted after controlling for level of pain catastrophizing and depression. CONCLUSIONS: Migraine sufferers exhibited impaired conditioned pain modulation of the nociceptive blink reflex, suggesting a deficiency in inhibition of trigeminal nociception, which may contribute to the development of migraine headaches.

Spreading the News: History, Successes, Challenges and the Ethics of Effective Dissemination.

Behavior analysts are responsible for disseminating behavior analysis by making information about the science available to the public, professional peers, and government officials. The purposes of the current paper are to outline the dissemination efforts of professional associations in the field of behavior analysis; to highlight the parallel efforts to disseminate and establish behavior analysis as a profession, including the evolution and growth of certification; to share examples of dissemination successes; to describe some challenges that have been faced when disseminating behavior analysis internationally; and to suggest some strategies for ethical and effective dissemination of behavior analysis.

Catastrophizing, pain, and functional outcomes for children with chronic pain: a meta-analytic review.

Pediatric chronic pain is associated with numerous negative outcomes including increased physical disability, increased rates of depression and anxiety, and decreased quality of life (QOL). Pain catastrophizing-broadly conceptualized as including rumination, magnification, and helplessness cognitions surrounding one's pain-has been linked with poor functional outcomes in children with chronic pain. Pain catastrophizing in pediatric chronic pain is often considered a key factor on which to focus treatment efforts. However, absent a systematic review that integrates the relevant literature, this call for routine assessment and targeted treatment may be premature. This study aimed to: (1) meta-analytically quantify the relationship between catastrophizing and pain and functional/psychosocial outcomes (functional disability/physical functioning, anxiety, depression, and QOL) in children with chronic pain, and (2) examine potential moderators of these relationships. Using a random-effects model, a total of 111 effect sizes from 38 studies were analyzed. Effect sizes ranged from medium to large, with anxiety, depression, and QOL demonstrating a strong association with catastrophizing. Pain intensity and physical disability had a moderate association with catastrophizing. These relationships were robust, minimizing potential publication bias. None of the examined moderators were significant. The strong relationships found between catastrophizing and anxiety, depression, and QOL suggest that successfully intervening on catastrophizing could have far reaching implications in improving pain outcomes in pediatric chronic pain.

Injustice perceptions about pain: parent-child discordance is associated with worse functional outcomes.

Pain is experienced within and influenced by social environments. For children with chronic pain, the child-parent relationship and parental beliefs about pain are particularly important and may influence pain outcomes. Pain-related injustice perceptions have recently been identified as an important cognitive-emotional factor for children with pain. The current study aimed to better understand the pain-related injustice perceptions of children with chronic pain and their parents. The sample consisted of 253 pediatric chronic pain patients (mean age = 14.1 years, 74% female) presenting to a tertiary pain clinic. Patients completed measures of pain intensity, pain-related injustice perceptions, stress, functional disability, and quality of life. Parents completed a measure of pain-related injustice perceptions about their child's pain. Child-parent dyads were categorized into 1 of 4 categories based on the degree of concordance or discordance between their scores on the injustice measures. One-way analysis of variances examined differences in pain intensity, stress, functional disability, and quality of life across the 4 dyad categories. Our findings indicated that both the degree (concordant vs discordant) and direction (discordant low child-high parent vs discordant high child-low parent) of similarity between child and parent injustice perceptions were associated with child-reported pain intensity, stress, functional disability, and quality of life. The poorest outcomes were reported when children considered their pain as highly unjust, but their parents did not. These findings highlight the important role of parents in the context of pain-related injustice perceptions in pediatric chronic pain.
