Abstract
Objective The purpose of this study was to increase our understanding of VCPs' impact on the therapeutic factor emotion processing by investigating possible differences in emotional activation during autobiographical recall in VCPs and in person. Methods We recruited 30 adult participants aged 21-53 (M = 26.50, SD = 6.68) with no current psychiatric diagnoses to join a controlled experiment. All participants completed two relaxation sessions and two autobiographical recall sessions. Each type of session was delivered once over a VCP and once in person. Emotional activation was measured by heart rate, skin conductance and self-assessment of affects during each session. Results No significant differences in activation during autobiographical recall between VCP and in person. Conclusions This result may indicate the viability of VCPs for work with emotion processing. We discuss the results in light of clients' and therapists' concerns about using VCPs in emotional work, with the caution that further practical implications should be considered.

Abstract
Background In recent years, mood induction procedures have been developed in experimental settings that are designed to facilitate studying the impact of mood states on biological and psychological processes. The aim of the present study was to conduct a systematic mapping review with the intention of describing the state of the art in the use of different types of autobiographical stimuli for mood induction procedures. Methods Based on a search for publications from the period 2000–2021, conducted in four recognised databases (Scopus, Medline (PubMed), PsycINFO and Web of Science), we analysed a total of 126 published articles. Text mining techniques were used to extract the main themes related. Results The induction of emotions through autobiographical memories is an area under construction and of growing interest. The data mining approach yielded information about the main types of stimuli used in these procedures, highlighting those that only employ a single type of cue, as well as the preference for verbal cues over others such as musical, olfactory and visual cues. This type of procedure has been used to induce both positive and negative emotions through tasks that require access to personal memories of specific events from a cue, requiring the person to set in motion different cognitive processes. The use of the latest technologies (fMRI, EEG, etc.) is also shown, demonstrating that this is a cutting-edge field of study. Conclusions Despite the study of mood induction procedures still being a growing field, the present review provides a novel overview of the current state of the art in the field, which may serve as a framework for future studies on the topic.

The Link between Fibromyalgia Syndrome and Anger: A Systematic Review Revealing Research Gaps. J Clin Med 2022; 11:jcm11030844. [PMID: 35160295 PMCID: PMC8836473 DOI: 10.3390/jcm11030844] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Revised: 01/29/2022] [Accepted: 02/02/2022] [Indexed: 12/19/2022] Open
Abstract
Anger has been associated with increased pain perception, but its specific connection with Fibromyalgia Syndrome (FMS) has not yet been established in an integrated approach. Therefore, the present systematic review focuses on exploring this connection, and based on this connection, delimiting possible gaps in the research, altogether aimed at improving FMS clinical intervention and guiding future research lines. Anger is considered a basic negative emotion that can be divided into two dimensions: anger-in (the tendency to repress anger when it is experienced) and anger-out (the leaning to express anger through verbal or physical means). The current systematic review was performed based on the guidelines of the PRISMA and Cochrane Collaborations. The Prospective Register of Systematic Reviews (PROSPERO) international database was forehand used to register the review protocol. The quality of chosen articles was assessed and the main limitations and research gaps resulting from each scientific article were discussed. The search included PubMed, Scopus, and Web of Science databases. The literature search identified 13 studies eligible for the systematic review. Levels of anger-in have been shown to be higher in FMS patients compared to healthy participants, as well as patients suffering from other pain conditions (e.g., rheumatoid arthritis). FMS patients had also showed higher levels of state and trait anxiety, worry and angry rumination than other chronic pain patients. Anger seems to amplify pain especially in women regardless FMS condition but with a particularly greater health-related quality of life´s impact in FMS patients. In spite of the relevance of emotions in the treatment of chronic pain, including FMS, only two studies have proposed intervention programs focus on anger treatment. These two studies have observed a positive reduction in anger levels through mindfulness and a strength training program. In conclusion, anger might be a meaningful therapeutic target in the attenuation of pain sensitivity, and the improvement of the general treatment effects and health-related quality of life in FMS patients. More intervention programs directed to reduce anger and contribute to improve well-being in FMS patients are needed.

Abstract
OBJECTIVES Anger is a negative emotion characterized by antagonism toward someone or something, is rooted in an appraisal or attribution of wrongdoing, and is accompanied by an action tendency to undo the wrongdoing. Anger is prevalent in individuals with chronic pain, especially those with chronic primary pain. The associations between anger and pain-related outcomes (e.g., pain intensity, disability) have been examined in previous studies. However, to our knowledge, no systematic review or meta-analysis has summarized the findings of anger-pain associations through a focus on chronic primary pain. Hence, we sought to summarize the findings on the associations of anger-related variables with pain and disability in individuals with chronic primary pain. METHODS All studies reporting at least one association between anger-related variables and the two pain-related outcomes in individuals with chronic primary pain were eligible. We searched electronic databases using keywords relevant to anger and chronic primary pain. Multiple reviewers independently screened for study eligibility, data extraction, and methodological quality assessment. RESULTS Thirty-eight studies were included in this systematic review, of which 20 provided data for meta-analyses (2,682 participants with chronic primary pain). Of the included studies, 68.4% had a medium methodological quality. Evidence showed mixed results in the qualitative synthesis. Most anger-related variables had significant positive pooled correlations with small to moderate effect sizes for pain and disability. CONCLUSIONS Through a comprehensive search, we identified several key anger-related variables associated with pain-related outcomes. In particular, associations with perceived injustice were substantial.

THE JOURNAL OF PAIN 2020; 22:509-519. [PMID: 33253818 DOI: 10.1016/j.jpain.2020.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 09/28/2020] [Accepted: 10/17/2020] [Indexed: 11/16/2022]
Abstract
Emotion has a strong modulatory effect on pain perception and spinal nociception. Pleasure inhibits pain and nociception, whereas displeasure facilitates pain and nociception. Dysregulation of this system has been implicated in development and maintenance of chronic pain. The current study sought to examine whether emotional modulation of pain could be altered through the use of transcranial direct current stimulation (tDCS) to enhance (via anodal stimulation) or depress (via cathodal stimulation) cortical excitability in the dorsolateral prefrontal cortex. Thirty-two participants (15 female, 17 male) received anodal, cathodal, and sham tDCS on three separate occasions, followed immediately by testing to examine the impact of pleasant and unpleasant images on pain and nociceptive flexion reflex (NFR) responses to electrocutaneous stimulation. Results indicated that tDCS modulated the effect of image content on NFR, F(2, 2175.06) = 3.20, P= .04, with the expected linear slope following anodal stimulation (ie, pleasant < neutral < unpleasant) but not cathodal stimulation. These findings provide novel evidence that the dorsolateral prefrontal cortex is critical to emotional modulation of spinal nociception. Moreover, the results suggest a physiological basis for a previously identified phenotype associated with risk for chronic pain and thus a potentially new target for chronic pain prevention efforts. PERSPECTIVE: This study demonstrated that reduction of dorsolateral prefrontal cortical excitability by transcranial direct current stimulation attenuates the impact of emotional image viewing on nociceptive reflex activity during painful electrocutaneous stimulation. This result confirms there is cortical involvement in emotional modulation of spinal nociception and opens avenues for future clinical research.

Abstract
Experiencing pain, especially when chronic, is an excruciating condition that should be regarded as a syndrome, if not a disease. People suffering from chronic pain tend to develop psychological discomfort mostly due to lack of acceptance, disbelief, blame. The complexity of pain pathophysiology, plus a wide range of negative psychosocial factors, leads to a more complex suffering that deserves attention and multidisciplinary treatments. The possibility that chronic pain may occur following physical aggression, torture, or persecution raises the issue of evil as a major contributor to pain in its worst representation - when individuals or groups are attacked based on racial, social, gender, religious, political, or other grounds. To explore the complex issue of chronic pain following physical or psychological harm, and to underscore the need for a multidisciplinary approach to reduce the burden of chronic pain, we discuss the biological mechanisms underlying pain state. We seek to clarify those factors leading to pain chronification, as well as personal and social attitudes that confound patients with chronic pain. The importance of family and social environment is also investigated, as well as personality traits of chronic pain patients that may further hamper successful treatment. The presence of chronic pain, modulated by, for example, acceptance of being a victim of premeditated physical and social violence, makes the issue more difficult to comprehend.

Abstract
BACKGROUND The tendency to inhibit anger (anger-in) is associated with increased pain. This relationship may be explained by the negative affectivity hypothesis (anger-in increases negative affect that increases pain). Alternatively, it may be explained by the cognitive resource hypothesis (inhibiting anger limits attentional resources for pain modulation). METHODS A well-validated picture-viewing paradigm was used in 98 healthy, pain-free individuals who were low or high on anger-in to study the effects of anger-in on emotional modulation of pain and attentional modulation of pain. Painful electrocutaneous stimulations were delivered during and in between pictures to evoke pain and the nociceptive flexion reflex (NFR; a physiological correlate of spinal nociception). Subjective and physiological measures of valence (ratings, facial/corrugator electromyogram) and arousal (ratings, skin conductance) were used to assess reactivity to pictures and emotional inhibition in the high anger-in group. RESULTS The high anger-in group reported less unpleasantness, showed less facial displays of negative affect in response to unpleasant pictures, and reported greater arousal to the pleasant pictures. Despite this, both groups experienced similar emotional modulation of pain/NFR. By contrast, the high anger-in group did not show attentional modulation of pain. CONCLUSIONS These findings support the cognitive resource hypothesis and suggest that overuse of emotional inhibition in high anger-in individuals could contribute to cognitive resource deficits that in turn contribute to pain risk. Moreover, anger-in likely influenced pain processing predominantly via supraspinal (e.g., cortico-cortical) mechanisms because only pain, but not NFR, was associated with anger-in.

Abstract
In a novel pilot study, we investigated how emotional state is related to inflammatory responses to acute pain among women with rheumatoid arthritis. Nine women completed four 5-hour visits that varied only by manipulation of emotion (anger, sadness, happiness, vs. control); in each visit, acute pain was elicited, with blood draws at baseline, 10 minutes, 60 minutes, and 100 minutes post-pain. We examined the effects of within-subjects factors on circulating inflammatory biomarkers interleukin (IL)-6, IL-10, tumor necrosis factor-α, C-reactive protein, and cortisol. There was a main effect of state anger on IL-6, with higher reported anger associated with higher IL-6 across conditions. Further, there were several interactions between state emotion and condition. For example, when individuals reported higher state anger in the sadness condition compared to their own average, they showed higher levels of IL-6 and cortisol. Findings are discussed within a larger literature suggesting that mixed emotional states can contribute to psychological stress and inflammatory responses.

Abstract
BACKGROUND Anger expression styles are associated with physical health, and may affect health by modulating anger experience in daily life. Research examining this process in the daily lives of clinically relevant populations, such as patients with chronic disease, is needed. METHOD Community adults with asthma (N = 97) or rheumatoid arthritis (RA; N = 31) completed measures of trait-level anger expression styles (anger-in and anger-out), followed by ecological momentary assessments of anger and physical health five times daily for 7 days. RESULTS High anger-in predicted greater momentary anger, physical limitations, and greater asthma symptoms. High anger-out predicted reduced RA symptoms. Momentary anger was robustly associated with more severe symptoms in daily life. Three-way interactions showed that anger-in moderated these momentary anger-symptom associations more consistently in men. CONCLUSIONS Anger expression styles, particularly anger-in, may affect the day-to-day adjustment of patients with chronic disease in part by altering the dimensions of everyday anger experience, in ways that appear to differ by gender.

Abstract
STUDY DESIGN Randomized, controlled pilot trial. OBJECTIVE The present study is the first randomized, double-blind, sham-controlled pilot clinical trial of transcranial direct current stimulation (tDCS) for pain and patient-controlled analgesia (PCA) opioid usage among patients receiving spine surgery. SUMMARY OF BACKGROUND DATA Lumbar spinal surgeries are common, and while pain is often a complaint that precedes surgical intervention, the procedures themselves are associated with considerable postoperative pain lasting days to weeks. Adequate postoperative pain control is an important factor in determining recovery and new analgesic strategies are needed that can be used adjunctively to existing strategies potentially to reduce reliance on opioid analgesia. Several novel brain stimulation technologies including tDCS are beginning to demonstrate promise as treatments for a variety of pain conditions. METHODS Twenty-seven patients undergoing lumbar spine procedures at Medical University of South Carolina were randomly assigned to receive four 20-minute sessions of real or sham tDCS during their postsurgical hospital stay. Patient-administered hydromorphone usage was tracked along with numeric rating scale pain ratings. RESULTS The effect of tDCS on the slope of the cumulative PCA curve was significant (P < 0.001) and tDCS was associated with a 23% reduction in PCA usage. In the real tDCS group a 31% reduction was observed in pain-at-its-least ratings from admission to discharge (P = 0.027), but no other changes in numeric rating scale pain ratings were significant in either group. CONCLUSION The present pilot trial is the first study to demonstrate an opioid sparing effect of tDCS after spine surgical procedures. Although this was a small pilot trial in a heterogeneous sample of spinal surgery patients, a moderate effect-size was observed for tDCS, suggesting that future work in this area is warranted.

Abstract
The claim that listening to extreme music causes anger, and expressions of anger such as aggression and delinquency have yet to be substantiated using controlled experimental methods. In this study, 39 extreme music listeners aged 18-34 years were subjected to an anger induction, followed by random assignment to 10 min of listening to extreme music from their own playlist, or 10 min silence (control). Measures of emotion included heart rate and subjective ratings on the Positive and Negative Affect Scale (PANAS). Results showed that ratings of PANAS hostility, irritability, and stress increased during the anger induction, and decreased after the music or silence. Heart rate increased during the anger induction and was sustained (not increased) in the music condition, and decreased in the silence condition. PANAS active and inspired ratings increased during music listening, an effect that was not seen in controls. The findings indicate that extreme music did not make angry participants angrier; rather, it appeared to match their physiological arousal and result in an increase in positive emotions. Listening to extreme music may represent a healthy way of processing anger for these listeners.

Abstract
BACKGROUND AND PURPOSE Stress contributes to headaches, and effective interventions for headaches routinely include relaxation training (RT) to directly reduce negative emotions and arousal. Yet, suppressing negative emotions, particularly anger, appears to augment pain, and experimental studies suggest that expressing anger may reduce pain. Therefore, we developed and tested anger awareness and expression training (AAET) on people with headaches. METHODS Young adults with headaches (N = 147) were randomized to AAET, RT, or a wait-list control. We assessed affect during sessions, and process and outcome variables at baseline and 4 weeks after treatment. RESULTS On process measures, both interventions increased self-efficacy to manage headaches, but only AAET reduced alexithymia and increased emotional processing and assertiveness. Yet, both interventions were equally effective at improving headache outcomes relative to controls. CONCLUSIONS Enhancing anger awareness and expression may improve chronic headaches, although not more than RT. Researchers should study which patients are most likely to benefit from an emotional expression or emotional reduction approach to chronic pain.

Anger regulation style, anger arousal and acute pain sensitivity: evidence for an endogenous opioid "triggering" model. J Behav Med 2013; 37:642-53.

Abstract
Findings suggest that greater tendency to express anger is associated with greater sensitivity to acute pain via endogenous opioid system dysfunction, but past studies have not addressed the role of anger arousal. We used a 2 × 2 factorial design with Drug Condition (placebo or opioid blockade with naltrexone) crossed with Task Order (anger-induction/pain-induction or pain-induction/anger-induction), and with continuous Anger-out Subscale scores. Drug × Task Order × Anger-out Subscale interactions were tested for pain intensity during a 4-min ischemic pain task performed by 146 healthy people. A significant Drug × Task Order × Anger-out Subscale interaction was dissected to reveal different patterns of pain intensity changes during the pain task for high anger-out participants who underwent pain-induction prior to anger-induction compared to those high in anger-out in the opposite order. Namely, when angered prior to pain, high anger-out participants appeared to exhibit low pain intensity under placebo that was not shown by high anger-out participants who received naltrexone. Results hint that people with a pronounced tendency to express anger may suffer from inadequate opioid function under simple pain-induction, but may experience analgesic benefit to some extent from the opioid triggering properties of strong anger arousal.

Associations between daily chronic pain intensity, daily anger expression, and trait anger expressiveness: an ecological momentary assessment study. Pain 2012; 153:2352-2358. [PMID: 22940462 DOI: 10.1016/j.pain.2012.08.001] [Citation(s) in RCA: 54] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2012] [Revised: 07/03/2012] [Accepted: 08/01/2012] [Indexed: 11/24/2022]
Abstract
Links between elevated trait anger expressiveness (anger-out) and greater chronic pain intensity are well documented, but pain-related effects of expressive behaviors actually used to regulate anger when it is experienced have been little explored. This study used ecological momentary assessment methods to explore prospective associations between daily behavioral anger expression and daily chronic pain intensity. Forty-eight chronic low back pain (LBP) patients and 36 healthy controls completed electronic diary ratings of momentary pain and behavioral anger expression in response to random prompts 4 times daily for 7 days. Across groups, greater trait anger-out was associated with greater daily behavioral anger expression (P<0.001). LBP participants showed higher levels of daily anger expression than controls (P<0.001). Generalized estimating equation analyses in the LBP group revealed a lagged main effect of greater behavioral anger expression on increased chronic pain intensity in the subsequent assessment period (P<0.05). Examination of a trait×situation model for anger-out revealed prospective associations between elevated chronic pain intensity and later increases in behavioral anger expression that were restricted largely to individuals low in trait anger-out (P<0.001). Trait×situation interactions for trait anger suppression (anger-in) indicated similar influences of pain intensity on subsequent behavioral anger expression occurring among low anger-in persons (P<0.001). Overlap with trait and state negative affect did not account for study findings. This study for the first time documents lagged within-day influences of behavioral anger expression on subsequent chronic pain intensity. Trait anger regulation style may moderate associations between behavioral anger expression and chronic pain intensity.

Abstract
Suppression of anger may be linked to heightened pain report and pain behavior during a subsequent painful event among chronic low back patients, but it is not clear whether these effects are partly accounted for by increased physiological reactivity during suppression. Chronic low back pain patients (N = 58) were assigned to Suppression or No Suppression conditions for a "cooperative" computer maze task during which a confederate harassed them. During baseline and maze task, patients' lower paraspinal and trapezius muscle tension, blood pressure and heart rate were recorded. After the maze task, patients underwent a structured pain behavior task (behaviors were videotaped and coded). Results showed that: (a) Suppression condition patients revealed greater lower paraspinal muscle tension and systolic blood pressure (SBP) increases during maze task than No Suppression patients (previously published results showed that Suppression condition patients exhibited more pain behaviors than No Suppression patients); (b) residualized lower paraspinal and SBP change scores were related significantly to pain behaviors; (c) both lower paraspinal and SBP reactivity significantly mediated the relationship between Condition and frequency of pain behaviors. Results suggest that suppression-induced lower paraspinal muscle tension and SBP increases may link the actual suppression of anger during provocation to signs of clinically relevant pain among chronic low back pain patients.

Abstract
OBJECTIVE Elevated trait anger (TRANG; heightened propensity to experience anger) is associated with greater pain responsiveness, possibly via associations with deficient endogenous opioid analgesia. This study tested whether acute anger arousal moderates the impact of TRANG on endogenous opioid analgesia. METHODS Ninety-four chronic low back pain (LBP) participants and 85 healthy controls received opioid blockade (8 mg of naloxone) or placebo in a randomized, counterbalanced order in separate sessions. Participants were randomly assigned to undergo either a 5-minute anger recall interview (ARI) or a neutral control interview across both drug conditions. Immediately after the assigned interview, participants engaged sequentially in finger pressure and ischemic forearm pain tasks. Opioid blockade effects were derived (blockade minus placebo condition pain ratings) to index opioid antinociceptive function. RESULTS Placebo condition TRANG by interview interactions (p values < .05) indicated that TRANG was hyperalgesic only in the context of acute anger arousal (ARI condition; p values < .05). Blockade effect analyses suggested that these hyperalgesic effects were related to deficient opioid analgesia. Significant TRANG by interview interactions (p values < .05) for both pain tasks indicated that elevated TRANG was associated with smaller blockade effects (less endogenous opioid analgesia) only in the ARI condition (p values < .05). Results for ischemic task visual analog scale intensity blockade effects suggested that associations between TRANG and impaired opioid function were most evident in LBP participants when experiencing anger (type by interview by TRANG interaction; p < .05). CONCLUSIONS Results indicate that hyperalgesic effects of TRANG are most prominent when acute anger is aroused and suggest that endogenous opioid mechanisms contribute.

Abstract
BACKGROUND Suppression of anger is linked to subsequent pain intensity among chronic low back patients, but it is not clear whether anger regulation style (trait anger-out, anger-in) moderates these effects or if aroused anger accounts for links between anger regulation style and pain. METHOD Chronic low back pain patients (N=58) were assigned to Suppression or No Suppression conditions for a task with harassing confederate and then underwent structured pain behavior procedures. Spielberger Anger Expression Inventory tapped trait anger-out (AOS) and anger-in (AIS). RESULTS Regressions tested Emotion Regulation condition × AOS and AIS effects on outcomes. AOS was related to grimacing and sighing for Suppression condition patients. AIS was related negatively to guarding and bracing for Suppression condition patients. Anger report partly mediated effects for AOS and AIS. CONCLUSIONS Anger regulation style moderated effects of state anger suppression on subsequent pain behaviors, effects that were partly explained by aroused anger.

Abstract
OBJECTIVES To compare self-reports of five basic emotions across four samples: healthy, chronic pain, depressed and post-traumatic stress disorder (PTSD), and to investigate the extent to which basic emotion reports discriminate between individuals in healthy or clinical groups. METHODS In total, 439 participants took part in this study: healthy (n = 131), chronic pain (n = 220), depressed (n = 24) and PTSD (n = 64). The participants completed the trait version of the Basic Emotion Scale. Basic emotion profiles were compared both within each group and between the healthy group and each of the three other groups. Discriminant analysis was used to assess the extent to which basic emotions can be used to classify the participants as belonging to the healthy group or one of the clinical groups. RESULTS In the healthy group, happiness was experienced more than any other basic emotion. This was not found in the clinical groups. In comparison to the healthy participants, the chronic pain group experienced more fear, anger and sadness, the depressed group reported more sadness and the PTSD group experienced all of the negative emotions more frequently. Discriminant analysis revealed that happiness was the most important variable in determining whether an individual belonged to the healthy group or one of the clinical groups. Anger was found to further discriminate between depressed and chronic pain individuals. CONCLUSION The findings demonstrate that basic emotion profile analysis can provide a useful foundation for the exploration of emotional experience both within and between healthy and clinical groups.

Abstract
This case report presents data regarding endogenous opioid analgesia in a healthy female subject prior to developing chronic pain, and again 4 and 13 months following onset of chronic daily back pain. At each assessment period, the subject underwent identical protocols involving two sessions one week apart with randomized double-blind crossover administration of saline placebo and naloxone, an opioid antagonist. Each session included a 5-min anger recall interview, followed by finger pressure and ischemic acute pain tasks. Increases in acute pain ratings induced by opioid blockade were interpreted as reflecting endogenous opioid analgesia. When the subject was healthy and pain-free, naloxone produced a mean overall 16% decrease in pain ratings relative to placebo. However, 4 months after onset of chronic pain, a mean naloxone-induced increase of 22% in pain ratings over placebo was observed, consistent with presence of endogenous opioid analgesia. The mean magnitude of this opioid blockade effect for the finger pressure task exceeded the 99% confidence interval for the healthy control population based on a previous study using a similar opioid blockade protocol [4]. At 13-month follow-up, naloxone produced a mean 45% decrease in acute pain ratings compared to placebo, arguing against presence of endogenous opioid analgesia. Although results must be interpreted cautiously, findings are consistent with the hypothesis that chronic pain may initially be associated with upregulation of endogenous opioid analgesic systems which then may become dysfunctional over time.

Abstract
Evidence suggests that anger and pain are related, yet it is not clear by what mechanisms anger may influence pain. We have proposed that effects of anger states and traits on pain sensitivity are partly opioid mediated. In this study, we test the extent to which analgesic effects of acute anger arousal on subsequent pain sensitivity are opioid mediated by subjecting healthy participants to anger-induction and pain either under opioid blockade (oral naltrexone) or placebo. Participants were 160 healthy individuals. A double-blind, placebo-controlled, between-subjects opioid blockade design is used, with participants assigned randomly to one of two drug conditions (placebo or naltrexone), and to one of two Task Orders (anger-induction followed by pain or vice versa). Results of ANOVAs show significant Drug Condition x Task Order interactions for sensory pain ratings (MPQ-Sensory) and angry and nervous affect during pain-induction, such that participants who underwent anger-induction prior to pain while under opioid blockade (naltrexone) reported more pain, and anger and nervousness than those who underwent the tasks in the same order, but did so on placebo. Results suggest that for people with intact opioid systems, acute anger arousal may trigger endogenous opioid release that reduces subsequent responsiveness to pain. Conversely, impaired endogenous opioid function, such as that found among some chronic pain patients, may leave certain people without optimal buffering from the otherwise hyperalgesic affects of anger arousal, and so may lead to greater pain and suffering following upsetting or angry events.

Abstract
OBJECTIVES To examine whether high trait anger-out chronic low back (CLBP) patients would show exceptionally large symptom-specific lower paraspinal (LP) responses, compared with healthy nonpatients, during pain induction, a subsequent mental stressor, and recovery when they were urged to suppress awareness of pain and suffering. METHODS CLBP patients (n = 93) and nonpatients (n = 105) were assigned randomly to one of four attention strategy conditions for use during pain induction: sensory-focus, distraction, suppression, or control. All participants underwent a cold pressor, and then performed mental arithmetic. They completed the anger-out (AOS) and anger-in (AIS) subscales of the Anger Expression Inventory. RESULTS General Linear Model procedures were used to test Attention Strategy Condition x Patient/Nonpatient Status x AOS (or AIS) x Period interactions for physiological indices. Significant interactions were found such that: a) high trait anger-out patients in the Suppression condition seemed to show the greatest LP reactivity during the mental arithmetic followed by the slowest recovery compared with other conditions; b) high trait anger-out patients and nonpatients in the Suppression condition seemed to show the slowest systolic blood pressure recoveries compared with other conditions. CONCLUSIONS Results extend previous work by suggesting that an anger-out style moderates effects of how attention is allocated during pain on responses to and recovery from a subsequent mental stressor. Results provide further evidence that trait anger-out and trait anger-in among CLBP patients are associated with increased LP muscle tension during and after pain and mental stress.

Abstract
BACKGROUND Fibromyalgia is characterized by an amplified pain response to various physical stimuli. Through biological and behavioural mechanisms, patients with fibromyalgia may also show an increase of pain in response to emotions. Anger, and how it is regulated, may be particularly important in chronic pain. AIM To examine, among patients with fibromyalgia, whether anger during everyday life amplifies pain and whether general and situational anger inhibition and anger expression modulate the anger-pain link. METHODS For 28 consecutive days, 333 women with fibromyalgia (mean age 47+/-12years) reported their transient anger and state anger inhibition (anger-in) and expression (anger-out) responses regarding a significant emotional event during the day as well as end-of-day pain. Trait anger inhibition and expression were assessed by questionnaire. Multilevel regression analyses were performed. RESULTS State anger predicted higher end-of-day pain (p<.001) in half of the patients, but lower pain in one-quarter of patients. State anger inhibition was unrelated to pain. Trait anger inhibition was related to more pain (p=.02). The lowest pain level was observed among patients with high trait anger expression who actually expressed their anger in an anger-arousing situation (p=.02). CONCLUSIONS Our study suggests that anger and a general tendency to inhibit anger predicts heightened pain in the everyday life of female patients with fibromyalgia. Psychological intervention could focus on healthy anger expression to try to mitigate the symptoms of fibromyalgia.

Abstract
Literature is reviewed indicating that greater tendency to manage anger via direct verbal or physical expression (trait anger-out) is associated with increased acute and chronic pain responsiveness. Neuroimaging data are overviewed supporting overlapping neural circuits underlying regulation of both pain and anger, consisting of brain regions including the rostral anterior cingulate cortex, orbitofrontal cortex, anterior insula, amygdala, and periaqueductal gray. These circuits provide a potential neural basis for observed positive associations between anger-out and pain responsiveness. The role of endogenous opioids in modulating activity in these interlinked brain regions is explored, and implications for understanding pain-related effects of anger-out are described. An opioid dysfunction hypothesis is presented in which inadequate endogenous opioid inhibitory activity in these brain regions contributes to links between trait anger-out and pain. A series of studies is presented that supports the opioid dysfunction hypothesis, further suggesting that gender and genetic factors may moderate these effects. Finally, possible implications of interactions between trait anger-out and state behavioral anger expression on endogenous opioid analgesic activity are described.

Abstract
OBJECTIVES We examined whether "state" anger regulation-inhibition or expression-among chronic low back pain (CLBP) patients would affect lower paraspinal (LP) muscle tension following anger-induction, and whether these effects were moderated by trait anger management style. METHOD Eighty-four CLBP patients underwent harassment, then they regulated anger under one of two conditions: half expressed anger by telling stories about people depicted in pictures, whereas half inhibited anger by only describing objects appearing in the same pictures. They completed the anger-out and anger-in subscales (AOS; AIS) of the anger expression inventory. RESULTS General Linear Model procedures were used to test anger regulation condition by AOS/AIS by period interactions for physiological indexes. Significant three-way interactions were found such that: a) high trait anger-out patients in the inhibition condition appeared to show the greatest LP reactivity during the inhibition period followed by the slowest recovery; b) high trait anger-out patients in the expression condition appeared to show the greatest systolic blood pressure (SBP) reactivity during the expression period followed by rapid recovery. CONCLUSIONS Results implicate LP muscle tension as a potential physiological mechanism that links the actual inhibition of anger following provocation to chronic pain severity among CLBP patients. Results also highlight the importance of mismatch situations for patients who typically regulate anger by expressing it. These CLBP patients may be at particular risk for elevated pain severity if circumstances at work or home regularly dictate that they should inhibit anger expression.

Abstract
Catastrophizing about pain is related to elevated pain severity and poor adjustment among chronic pain patients, but few physiological mechanisms by which pain catastrophizing maintains and exacerbates pain have been explored. We hypothesized that resting levels of lower paraspinal muscle tension and/or lower paraspinal and cardiovascular reactivity to emotional arousal may: (a) mediate links between pain catastrophizing and chronic pain intensity; (b) moderate these links such that only patients described by certain combinations of pain catastrophizing and physiological indexes would report pronounced chronic pain. Chronic low back pain patients (N = 97) participated in anger recall and sadness recall interviews while lower paraspinal and trapezius EMG and systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were recorded. Mediation models were not supported. However, pain catastrophizing significantly interacted with resting lower paraspinal muscle tension to predict pain severity such that high catastrophizers with high resting lower paraspinal tension reported the greatest pain. Pain catastrophizing also interacted with SBP, DBP and HR reactivity to affect pain such that high catastrophizers who showed low cardiovascular reactivity to the interviews reported the greatest pain. Results support a multi-variable profile approach to identifying pain catastrophizers at greatest risk for pain severity by virtue of resting muscle tension and cardiovascular stress function.

Abstract
Both trait anger-in (managing anger through suppression) and anger-out (managing anger through direct expression) are related to pain responsiveness, but only anger-out effects involve opioid mechanisms. Preliminary work suggested that the effects of anger-out on postoperative analgesic requirements were moderated by the A118G single nucleotide polymorphism of the mu opioid receptor gene. This study further explored these potential genotypexphenotype interactions as they impact acute pain sensitivity. Genetic samples and measures of anger-in and anger-out were obtained in 87 subjects (from three studies) who participated in controlled laboratory acute pain tasks (ischemic, finger pressure, thermal). McGill Pain Questionnaire (MPQ) Sensory and Affective ratings for each pain task were standardized within studies, aggregated across pain tasks, and combined for analyses. Significant anger-outxA118G interactions were observed (p's<.05). Simple effects tests for both pain measures revealed that whereas anger-out was nonsignificantly hyperalgesic in subjects homozygous for the wild-type allele, anger-out was significantly hypoalgesic in those with the variant G allele (p's<.05). For the MPQ-Affective measure, this interaction arose both from low pain sensitivity in high anger-out subjects with the G allele and heightened pain sensitivity in low anger-out subjects with the G allele relative to responses in homozygous wild-type subjects. No genetic moderation was observed for anger-in, although significant main effects on MPQ-Affective ratings were noted (p<.005). Anger-in main effects were due to overlap with negative affect, but anger-outxA118G interactions were not, suggesting unique effects of expressive anger regulation. Results support opioid-related genotypexphenotype interactions involving trait anger-out.

Abstract
Anger and how anger is regulated appear to affect acute and chronic pain intensity. The inhibition of anger (anger-in), in particular, has received much attention, and it is widely believed that suppressing or inhibiting the verbal or physical expression of anger is related to increased pain severity. We examine theoretical accounts for expecting that anger inhibition should affect pain, and review evidence for this claim. We suggest that the evidence for a link between trait anger-in (the self-reported tendency to inhibit anger expression when angry) and acute and chronic pain severity is quite limited owing to a number of factors including a inadequate definition of trait anger-in embodied in the popular anger-in subscale of Spielberger's Anger Expression Inventory, and a strong overlap between trait anger-in scores and measures of general negative affect (NA). We argue that in order to determine whether something unique to the process of anger inhibition exerts direct effects on subsequent pain intensity, new conceptualizations and approaches are needed that go beyond self-report assessments of trait anger-in. We present one model of anger inhibition and pain that adopts elements of Wegner's ironic process theory of thought suppression. Findings from this emerging research paradigm indicate that state anger suppression (suppression manipulated in the laboratory) may indeed affect sensitivity to subsequent painful stimuli, and we outline potentially productive avenues of future inquiry that build on this model. We conclude that although studies employing correlational designs and self-reports of trait anger-in have not upheld the claim that anger inhibition affects pain severity, evidence from studies using new models suggests that actually inhibiting anger expression during a provocative event may increase perceived pain at a later time.

Abstract
BACKGROUND There is evidence that chronic idiopathic urticaria (CIU) and psoriasis are associated with personality based difficulties in emotional regulation particularly with regard to the feeling of anger. This deficit in emotional awareness could lead to the phenomenon that emotions are rather experienced in bodily symptoms such as pruritus. AIM We investigated whether there is a relationship between pruritus as major symptoms in CIU and psoriasis and the experience of negative emotions. SETTING Forty-one CIU patients and 44 psoriasis patients treated at Bonn University Hospital and 49 healthy controls were included. METHOD Patients and controls were compared on questionnaires measuring alexithymia (TAS-20), emotional distress (SCL-90-R) and anger (STAXI). In skin-disordered patients, separate stepwise regressions with pruritus severity as dependent variable and questionnaires, skin status, duration, sex and age as independent variables were calculated. RESULTS CIU and psoriasis patients showed higher alexithymia, emotional distress, depression, anxiety and state anger compared with controls. State anger was the only significant predictor of pruritus severity in CIU explaining 19% of variance. Depression was the only significant predictor of pruritus severity in psoriasis explaining 12% of variance. CONCLUSIONS Our findings suggest a relationship between pruritus severity and anger in CIU. Furthermore, our results indicate a relationship between pruritus severity and depression in psoriasis.

Abstract
This study explored possible gender moderation of previously reported associations between elevated trait anger-out and reduced endogenous opioid analgesia. One hundred forty-five healthy participants underwent acute electrocutaneous pain stimulation after placebo and oral opioid blockade in separate sessions. Blockade effects were derived reflecting changes in pain responses induced by opioid blockade. Hierarchical regressions revealed that elevated anger-out was associated with smaller pain threshold blockade effects (less opioid analgesia) in females, with opposite findings in males (interaction p < .001). Similar marginally significant interactions were noted for blockade effects derived for nociceptive flexion reflex threshold, pain tolerance, and pain ratings (p < .10). Anger-in was also associated negatively with pain threshold blockade effects in females but not males (interaction p < .05). Across genders, elevated anger-in was related to smaller pain tolerance blockade effects (p < .01). Overlap with negative affect did not account for these opioid effects. The anger-in/opioid association was partially due to overlap with anger-out, but the converse was not true. These findings provide additional evidence of an association between trait anger-out and endogenous opioid analgesia, but further suggest that gender may moderate these effects. In contrast to past work, anger-in was related to reduced opioid analgesia, although overlap with anger-out may contribute to this finding.

Abstract
The anger management styles of anger-in (inhibition) and anger-out (direct expression) are positively associated with pain responsiveness. Opioid blockade studies suggest that hyperalgesic effects of trait anger-out, but not those of trait anger-in, are mediated in part by opioid analgesic system dysfunction. The current study tested the opioid dysfunction hypothesis of anger-out using an alternative index of opioid function: pain-induced changes in plasma endogenous opioids. Plasma beta-endorphin (BE) was assessed at rest and again following exposure to three laboratory acute pain tasks (finger pressure, ischemic, and thermal) in 14 healthy controls and 13 chronic low back pain (LBP) subjects. As expected, acute pain ratings correlated positively with measures of anger-in (both groups) and anger-out (LBP group; p's<.05). Greater pain-induced increases in BE were associated with significantly lower pain ratings in both groups (p's<.05). Hierarchical multiple regression indicated that greater anger-out significantly predicted smaller pain-induced BE increases (p<.05). Subject type did not moderate this association (p>.10). Anger-in did not display significant main or interaction effects on pain-induced BE changes (p's>.10). The significant association between anger-out and BE release partially mediated the hyperalgesic effects of anger-out on pain unpleasantness, and was not attenuated by statistical control of general negative affect. This suggests unique associations with expressive anger regulation. Elevated trait anger-out therefore appears to be associated with opioid analgesic system dysfunction, whether it is indexed by responses to opioid blockade or by examining circulating endogenous opioid levels. Possible "statextrait" interactions on these anger-related opioid system differences are discussed.

Abstract
Anger may have greater effects on chronic pain severity than other negative emotions and may do so by increasing muscle tension near the site of injury (symptom-specific reactivity). For patients with chronic low back pain (CLBP), relevant muscles are lower paraspinals (LP). Ninety-four CLBP patients and 79 controls underwent anger and sadness recall interviews. EMG and cardiovascular activity were recorded. Patients exhibited greater LP tension increases during anger and slower recovery than controls. Only patients showed greater LP reactivity during anger than sadness. For both groups, trapezius reactivity during anger and sadness did not differ. LP reactivity to anger correlated with everyday pain severity for patients. Anger-induced symptom-specific LP reactivity may be linked to chronic pain aggravation among CLBP patients.

Abstract
Emotion and pain are psychological constructs that have received extensive attention in neuropsychological research. However, neuropsychological models of emotional processing have made more progress in describing how brain regions interact to process emotion. Theories of emotional processing can describe inter-hemispheric and intra-hemispheric interactions during emotional processing. Due to similarities between emotion and pain, it is thought that emotional models can be applied to pain. The following review examines the neuropsychology of emotion and pain using a functional cerebral systems approach. Specific comparisons are made between pain and anger. Attention is given to differences in cerebral function and physiology that may contribute to the processing of emotion and pain. Suggestions for future research in emotion and pain are given.

Abstract
OBJECTIVES We examined whether anger-in, anger-out, and hostility predicted symptom-specific muscle tension reactivity during anger induction (but not sadness induction) among patients with chronic low back pain (CLBP). For patients with CLBP, relevant muscles are the lower paraspinals (LPs). Anger-in x hostility and anger-out x hostility interactions were tested to determine whether particularly reactive groups of patients could be identified with a multivariable profile approach. METHODS Ninety-four patients with CLBP underwent anger recall (ARI) and sadness recall (SRI) interviews, whereas LP and trapezius electromyography and systolic blood pressure, diastolic blood pressure, and heart rate were recorded. They completed anger-in, anger-out, hostility, and trait anger measures. RESULTS Hierarchical regressions were used to test anger-in x hostility and anger-out x hostility interactions for physiological changes during the ARI and SRI. A significant anger-in x hostility interaction was found for LP change during the ARI (but not SRI) such that high anger-in/high hostility patients evinced the greatest reactivity. Effects for trapezius reactivity were nonsignificant. Significant anger-in x hostility interactions were also found for systolic blood pressure and diastolic blood pressure changes during the ARI such that high anger-in/low hostility patients showed the smallest changes. The anger-out x hostility interaction for diastolic blood pressure change during ARI was also significant such that high anger-out/low hostility patients showed the smallest changes. All effects remained significant with trait anger controlled. CONCLUSIONS A multivariable profile approach may help identify especially vulnerable patient groups. Patients with CLBP who tend to suppress anger and are cynically hostile may be more likely to experience high levels of muscle tension near the site of pain and injury during anger, but not during sadness, than other groups.

Abstract
OBJECTIVE Chronic low back pain (CLBP) is a widespread ailment. The aim of this study was to assess the efficacy of topiramate in the treatment of CLBP and the changes in anger status and processing, body weight, subjective pain-related disability and health-related quality of life during the course of treatment. METHODS We conducted a 10-week, randomized, double-blind, placebo-controlled study of topiramate in 96 (36 women) patients with CLBP. The subjects were randomly assigned to topiramate (n=48) or placebo (n=48). Primary outcome measures were changes on the McGill Pain Questionnaire, State-Trait Anger Expression Inventory, Oswestry Low Back Pain Disability Questionnaire and SF-36 Health Survey scales, and in body weight. RESULTS In comparison with the placebo group (according to the intent-to-treat principle), significant changes on the pain rating index of McGill Pain Questionnaire (Ps<0.001), State-Trait Anger Expression Inventory Scales (all Ps<0.001), Oswestry Low Back Pain Disability Questionnaire (P<0.001), and SF-36 Health Survey scales (all P<0.001, except on the role-emotional scale) were observed after 10 weeks in the patients treated with topiramate. Weight loss was also observed and was significantly more pronounced in the group treated with topiramate than in those treated with placebo (P<0.001). Most patients tolerated topiramate relatively well but 2 patients dropped out because of side effects. DISCUSSION Topiramate seems to be a relatively safe and effective agent in the treatment of CLBP. Significantly positive changes in pain sensitivity, anger status and processing, subjective disability, health-related quality of life, and loss of weight were observed.

Abstract
A tendency to manage anger via direct expression (anger-out) is increasingly recognized as influencing responses to pain. Elevated trait anger-out is associated with increased responsiveness to acute experimental and clinical pain stimuli, and is generally related to elevated chronic pain intensity in individuals with diverse pain conditions. Possible mechanisms for these links are explored, including negative affect, psychodynamics, central adipose tissue, symptom specific muscle reactivity, endogenous opioid dysfunction, and genetics. The opioid dysfunction hypothesis has some experimental support, and simultaneously can account for anger-out's effects on both acute and chronic pain. Factors which may moderate the anger-out/pain link are described, including narcotic use, gender, and genetic polymorphisms. Pain exacerbating effects of trait anger-out are contrasted with the apparent pain inhibitory effects of behavioral anger expression exhibited in anger-provoking contexts. Conceptual issues related to the state versus trait effects of expressive anger regulation are discussed.

Abstract
Anger management style is related to both acute and chronic pain. Recent research suggests that individuals who predominantly express anger (anger-out) may report heightened chronic pain severity due in part to endogenous opioid antinociceptive dysfunction. If exogenous opioids serve to remediate opioid deficits, we predicted that regular use of opioid analgesics by chronic pain patients would alter these relationships such that anger-out would be related to chronic pain severity only among opioid-free patients. For 136 chronic pain patients, anger management style, depression, anxiety, pain severity, and use of opioid and antidepressant medication was assessed. Results of hierarchical multiple regressions to predict chronic pain severity showed: (a) a significant Anger-out x Opioid use interaction such that high Anger-out was associated with high pain severity only among patients not taking opioids; (b) controlling for depressed affect and anxiety did not affect this association; (c) the Anger-out x Antidepressant use interaction was nonsignificant; (d) Anger-in did not interact with use of any medication to affect pain severity. Results are consistent with an opioid-deficit hypothesis and suggest that regular use of opioid medications by patients high in anger expression may compensate for an endogenous opioid deficit, and mitigate the effects of elevated anger expression on chronic pain intensity.

Abstract
Pain management is still an unresolved issue among the general elderly patient population in institutions. It is proposed that everyday emotion regulation (i.e. self-supporting maintenance or change in positive and negative emotions) performed by hospitalized elderly can help reduce pain intensity. This argument is based on (1) robust evidence in life span research of elderly's high ability for emotion regulation in the midst of everyday life and (2) experimental evidence from pain research that simple strategies to regulate emotions impact pain intensity. A prospective within-day study was designed to (1) empirically trace the occurrence of emotion regulation over specific sampling episodes, (2) assess the impact of this regulation on end-of-episode pain intensity, and (3) consider the effects of socio-demographic, psychological, and clinical factors on emotion regulation and its relationship to pain intensity. Thirty patients (mean age 78.8) of a geriatric facility provided ratings of emotional states and pain intensity. Emotion regulation was defined as maintenance/recovery of desirable emotional states and computed for individual emotions (positive feelings, anger, anxiety, and mild depressed feelings) and globally to reflect the number of emotions successfully regulated. Multilevel analyses found emotion regulation to be prospectively related to pain intensity, for both global and anxiety regulation. While this relationship held across the sample, lower emotion regulation was found for old-old (vs. young-old), males (vs. females), and patients living alone (vs. with others). Results suggest the possibility that promoting emotion regulation as self-management strategy could contribute to cost-effective pain management in general or targeted elderly populations.
