Patients with chronic pain demonstrate interpretational bias to pain and models of pain suggest interpretational bias affects subsequent pain experience. This study developed an interpretation bias modification for pain (IBM-P) and examined its efficacy. A total of 48 patients with chronic pain were recruited and randomly assigned to either the training group (n = 24) or the control group (n = 24). Interpretational bias, negative emotions, and attentional bias to pain-related stimuli were assessed before and after conducting IBM-P. The main results indicated that the training group showed less interpretational bias and negative emotions after IBM-P than the control group. The training group also gazed at neutral words longer than at "new" affective pain words after IBM-P than they did prior to the intervention. Furthermore, significant mediating effects of post-interpretational bias were found in the relationship between the group type and post-negative emotions and post-dwell time bias. These results suggest that IBM-P can modify interpretational bias which leads to changes in negative emotions and attentional bias. Future research is needed to confirm the effect of modifying interpretational bias and its clinical utility in the field of pain management. Perspective: This article investigated the efficacy of IBM-P and suggested that modifying interpretational bias is followed by changes in negative emotions and attentional bias. These findings may help health professionals understand the role of interpretational bias in chronic pain and encourage the potential use of IBM in pain management.

Pain problems tend to run in families and children of individuals with chronic pain (ICPs) have been found to report lower functioning. Drawing upon a social learning perspective, the current study examined how diverse maternal pain coping responses (i.e., pain catastrophizing and distraction) may, via corresponding child pain coping responses, act as a vulnerability or protective factor for child functioning in the context of parental chronic pain (CP).

The present study investigates how participants' locus of control and their family and friends' validation of their pain influences participants' chronic pain experiences. Four thousand, 25 adults were recruited through the Chronic Pain In America survey. Results show that individuals who endorse an internal locus of control and experience family and friends' validation of their chronic pain reported better chronic pain outcomes and less negative life impact due to chronic pain. The current results indicate the locus of control and family and friends' validation of chronic pain experience plays an important role in chronic pain and the impact of chronic pain across the life course.

The present study examined how multiple chronic pain conditions and pain sites are associated with socio-demographics, chronic pain adjustment profiles, and emotional distress. A total of 2407 individuals who reported at least six months of having consistent pain severity, pain interference, and/or emotional burden due to pain were recruited through random digit dialing across the United States. Participants' chronic pain adjustment profiles (i.e., pain intensity, pain interference, emotional burden, pain catastrophizing, pain coping, pain attitudes, and social resources) were assessed. Anxiety and depressive symptoms were also measured using a subsample of 181 participants who provided three-month follow-up data. More than 60% of individuals with chronic pain reported having multiple pain conditions. Middle-aged single women with fibromyalgia, disability and of low socioeconomic status reported a greater number of pain conditions and pain sites. Structural equation modeling revealed that a higher number of pain conditions and sites was associated with more dysfunctional chronic pain adjustment profiles. The subsample analyses showed that reporting a greater number of pain conditions predicted a higher level of depression and anxiety three months later, controlling for pain-related anxiety and depressive symptoms, pain severity and interference at baseline. Having multiple pain conditions and sites may represent a psychosocial barrier to successful adjustment to chronic pain. Perspectives: This article argues for the importance of assessing the number of co-occurring chronic pain conditions and bodily areas that are affected by pain in both pain research and clinical settings. Measuring and incorporating such information could potentially enhance our nascent understanding of the adjustment processes of chronic pain.

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, SE=.71, 95% 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, 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 (i.e., pain distress/pain interference) and treatment (i.e., 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.
