Abstract
BACKGROUND There is consistent evidence showing an interplay between psychological processes and immune function in health and disease processes. OBJECTIVES The present systematic review and meta-analysis aims to provide a concise overview of the effectiveness of stress-reducing psychological interventions on the activation of immune responses in both healthy subjects and patients. METHODS Included are 3 types of challenges: in vivo, in vitro, and psychophysiological. Such challenges are designed to mimic naturally occurring immune-related threats. RESULTS A systematic literature search was conducted using PubMed, EMBASE, and PsychInfo, resulting in 75 eligible studies. The risk of bias was assessed with the Cochrane risk-of-bias tool. Across all studies, a small-to-medium effect size was found for the effects of psychological interventions on optimization of the immune function (g = 0.33; 95% CI 0.22-0.43). While the largest effects were found for in vivo immune-related challenges (g = 0.61; 95% CI 0.34-0.88; especially on studies that incorporated skin tests and wound healing), studies incorporating psychophysiological challenges and in vitro immune-related stimulations similarly suggest more optimal immune responses among those receiving stress-reducing interventions (g = 0.28; 95% CI 0.15-0.42). CONCLUSION These findings showed substantial heterogeneity depending on the type of challenge, the study populations, and the intervention types. These data demonstrate support for the effectiveness of stress-reducing psychological interventions in improving immunity in studies that tested immune function by means of incorporating an in vivo,in vitro, or psychophysiological challenge. Future research should more consistently incorporate challenges into the study design to gather more insights in the mechanisms underlying the optimized immune function following a psychological intervention. This is also relevant for clinical practice, as psychological interventions can possibly supplement, or at least partially replace, current drug treatments in various somatic conditions to reduce side effects.

Abstract
Social stress can lead to the development of psychological problems ranging from exaggerated anxiety and depression to antisocial and violence-related behaviors. Increasing evidence suggests that the immune system is involved in responses to social stress in adulthood. For example, human studies show that individuals with high aggression traits display heightened inflammatory cytokine levels and dysregulated immune responses such as slower wound healing. Similar findings have been observed in patients with depression, and comorbidity of depression and aggression was correlated with stronger immune dysregulation. Therefore, dysregulation of the immune system may be one of the mediators of social stress that produces aggression and/or depression. Similar to humans, aggressive animals also show increased levels of several proinflammatory cytokines, however, unlike humans these animals are more protected from infectious organisms and have faster wound healing than animals with low aggression. On the other hand, subordinate animals that receive repeated social defeat stress have been shown to develop escalated and dysregulated immune responses such as glucocorticoid insensitivity in monocytes. In this review we synthesize the current evidence in humans, non-human primates, and rodents to show a role for the immune system in responses to social stress leading to psychiatric problems such as aggression or depression. We argue that while depression and aggression represent two fundamentally different behavioral and physiological responses to social stress, it is possible that some overlapped, as well as distinct, pattern of immune signaling may underlie both of them. We also argue the necessity of studying animal models of maladaptive aggression induced by social stress (i.e., social isolation) for understanding neuro-immune mechanism of aggression, which may be relevant to human aggression.

Abstract
Dominance contests are recurrent and widespread causes of stress among mammals. Studies of activation of the stress axis in social defeat – as reflected in levels of adrenal glucocorticoid, cortisol – have generated scattered and sometimes contradictory results, suggesting that biopsychological individual differences might play an important mediating role, at least in humans. In the context of a larger study of the regulation of endocrine responses to competition, we evaluated the notion that mood states, such as self-assurance and hostility, may influence cortisol reactivity to dominance cues via an interplay with baseline testosterone, considered as a potential marker of individual differences in dominance. Seventy healthy male university students (mean age 20.02, range 18–26) provided saliva samples before and after competing for fifteen minutes on a rigged computer task. After a winner was determined, all participants were assessed on their mood states through a standardized psychometric instrument (PANAS-X). Among winners of a rigged videogame competition, we found a significant interaction between testosterone and self-assurance in relation to post-competition cortisol. Specifically, self-assurance was associated with lower post-competition cortisol in subjects with high baseline testosterone levels, but no such relationship was observed in subjects with lower baseline testosterone levels. In losers of the competition no interaction effect between basal testosterone and hostility was observed. However, in this subgroup a significant negative relationship between basal testosterone and post-competition cortisol was evident. Overall, these findings provide initial support for the novel hypothesis that biological motivational predispositions (i.e. basal testosterone) and state (i.e. mood changes) may interact in regulating the hypothalamic-pituitary-adrenal axis activation after a social contest.

Abstract
Associations between psychological functioning and natural killer cell activity (NKA) were examined in 23 older (62.2 ± 7.5 years) family caregivers randomized to a moderate intensity four-month exercise program or to a wait-list control condition. At baseline, although NKA was related to anger-control (r = -.42; trend p < .06) and anger-out (r = .50; p < .03), it was not related to depression, anxiety, perceived stress, or caregiver burden. After controlling for baseline NKA, changes in anger-control explained 14 percent of the variance in NKA four months later. Decreases in anger-control predicted increases in NKA. Group assignment (exercise vs control) was unrelated to changes in NKA over the four-month period; however, the study was not powered to detect this effect. These results are consistent with reported relationships of anger expression with other physiological measures, and extend the importance of anger expression to immune functioning in older family caregivers.

Abstract
High levels of trait hostility are associated with wide-ranging interpersonal deficits and heightened physiological response to social stressors. These deficits may be attributable in part to individual differences in the perception of social cues. The present study evaluated the ability to recognize facial emotion among 48 high hostile (HH) and 48 low hostile (LH) smokers and whether experimentally-manipulated acute nicotine deprivation moderated relations between hostility and facial emotion recognition. A computer program presented series of pictures of faces that morphed from a neutral emotion into increasing intensities of happiness, sadness, fear, or anger, and participants were asked to identify the emotion displayed as quickly as possible. Results indicated that HH smokers, relative to LH smokers, required a significantly greater intensity of emotion expression to recognize happiness. No differences were found for other emotions across HH and LH individuals, nor did nicotine deprivation moderate relations between hostility and emotion recognition. This is the first study to show that HH individuals are slower to recognize happy facial expressions and that this occurs regardless of recent tobacco abstinence. Difficulty recognizing happiness in others may impact the degree to which HH individuals are able to identify social approach signals and to receive social reinforcement.

Abstract
High-trait hostility is associated with persistent cigarette smoking. To better understand mechanisms that may account for this association, we examined the effects of acute smoking abstinence and delayed versus immediate smoking reinstatement on responses to a social stressor among 48 low hostile (LH) and 48 high hostile (HH) smokers. Participants completed two laboratory sessions, one before which they had smoked ad lib and one before which they had abstained for the prior 12 hr. During each session, participants completed a stressful speaking task and then smoked immediately after the stressor or after a 15-min delay. The effect of immediate versus delayed smoking reinstatement on recovery in negative mood was significantly moderated by hostility. When reinstatement was delayed, HH participants showed significant increases in negative mood over time, whereas LH participants showed little change. When reinstatement was immediate, HH and LH smokers showed similar significant decreases in negative mood. Smoking abstinence did not moderate hostility effects. Cigarette smoking may prevent continuing increases in negative mood after social stress in HH smokers, which may partially explain their low rates of quitting.

Abstract
The idea that clients should be encouraged to express strong emotion regarding the traumas they have suffered is widely assumed. This article asks whether the empirical literature supports the underlying assumption that emotional expression leads to positive outcomes (better health and dissipation of distress). Studies in which individuals who have been given an opportunity to express emotions about past traumas are compared with subjects placed in appropriate control conditions are reviewed. The empirical literature suggests that eliciting emotion is harmful when it is not associated with reappraisal of past trauma, but helpful when the reappraisal occurs. The following guideline emerges: if trauma is to be revisited, it should be accompanied by reappraisal. Since this is sometimes difficult to engineer, alternative approaches for working with victims of trauma, not involving revisiting the trauma, are offered. Additionally, it is suggested that it can be helpful to identify the nature of the problem arising from the traumatic experience and then provide therapeutic intervention that addresses the problem.

Abstract
This study is a systematic review of mind-body interventions that used immune outcomes in order to: 1) characterize mind-body medicine studies that assessed immune outcomes, 2) evaluate the quality of mind-body medicine studies measuring immune system effects, and 3) systematically evaluate the evidence for mind-body interventions effect on immune system outcomes using existing formal tools. 111 studies with 4,777 subjects were reviewed. The three largest intervention type categories were Relaxation Training (n=25), Cognitive Based Stress Management (n=22), and Hypnosis (n=21). Half the studies were conducted with healthy subjects (n=51). HIV (n=18), cancer (n=13) and allergies (n=7) were the most prominent conditions examined in the studies comprising of non-healthy subjects. Natural killer cell and CD4 T lymphocyte measures were the most commonly studied outcomes. Most outcome and modality categories had limited or inconclusive evidence. Relaxation training had the strongest scientific evidence of a mind-body medicine affecting immune outcomes. Immunoglobulin A had the strongest scientific evidence for positive effects from mind-body medicine. Issues for mind-body medicine studies with immune outcomes are discussed and recommendations are made to help improve future clinical trials.

Abstract
OBJECTIVE The study aimed to analyze the correlation between lymphocyte counts and several psychopathological variables associated with psychological instability (depression, hostility, impulsivity, self-defeating personality traits, and borderline personality symptoms) in patients with bulimia nervosa (BN). METHOD Sixty BN patients were assessed, using specific scales for eating pathology, general psychopathology, impulsivity, depression, and borderline personality features. Lymphocyte and lymphocyte subset counts were performed. Plasma cortisol at 8:00, before and after administration of 1 mg of dexamethasone at 23:00, was determined. The influence of body weight, and the use of tobacco, alcohol, and caffeine was controlled. The relationship between each isolated variable and the number of immune cells was analyzed. In a second step, supplementary post-hoc analysis of the variables was introduced to confirm the accuracy of the psychopathological assessment. RESULTS Hostility was negatively correlated with the number of helper T-cells (CD4+). Patients with high hostility had lower CD4+ cell counts and lower CD4+/CD8+ ratios. In the post-hoc control study, hostility was significantly related with other "interpersonal" items. CONCLUSIONS These results support the idea that hostility, as an expression of disturbed interpersonal relationships, could play a role as a modulator of immune activity in patients with BN.

Abstract
Controversies exist regarding the impact of psychological stress on the functioning of the immune system in humans. The aim of the present study, therefore, was to evaluate whether the condition of a pre-exam stress may or not modify resting lymphocyte subsets, as well as blood pressure and heart rate. About 22 medical residents of both sexes not suffering from any medical or psychiatric disorder were included in the study. Anxiety levels were measured by means of the Hamilton rating scale for anxiety (HRSA) and anxiety traits by means of the panic-agoraphobic spectrum self-report (PAS-SR) version and the obsessive-compulsive spectrum self-report (OBS-SR) version. The results showed that systolic blood pressure and heart rate increased significantly just before sitting an examination (t(1)) in all subjects, as compared with a calm situation (t(2)), in parallel with the increase in the HRSA total score, while no significant difference was observed in lymphocyte subsets at the two assessment times. However, men had a higher number of CD4+ cells than women at t(1) and t(2), while women showed a higher heart rate at t(1). In addition, significant correlations between CD4+ lymphocyte count and heart rate at t(1) or HRSA at t(2) were detected. These findings indicate that the acute stress determined by sitting for examination provokes changes in autonomic nervous system parameters, such as blood pressure and heart rate, as well as in the subjective feeling of anxiety, as shown by the increased HRSA total scores, which were not paralleled by modifications of lymphocyte subsets. However, individual differences, related to both sex and personality traits yet to be identified, seem to have an impact in shaping the stress response.

Abstract
We examined the associations between productivity, employer characteristics, and context variables, and the organizational justice perceptions of 330 female employees in long-term institutional elderly people care. The productivity measure used was the proportion of the inpatient days to total costs. Employees working in high productivity units experienced higher procedural justice than those working in low productivity units. Hostile employees experienced both the procedures and management as less fair than non-hostile employees. Unit size and resident turnover were negatively and registered nurses percentage positively associated with procedural justice perceptions.

Abstract
This study examined the moderating effect of employee hostility on the association of unit-level resident characteristics (depression and behavioral problems) to individual-level employee's resident-related stress and psychological well-being during 1-year follow-up study among 501 employees in elderly care. Our results showed that employee hostility was associated with decreased psychological well-being. In addition, hostility moderated the association between unit-level proportion of depressive residents and resident-related stress experienced by the individual employees. Hostile employees reported increased resident-related stress irrespective of the proportion of depressed residents in the unit. Instead, nonhostile employees were sensitive to the depression in the unit. They reported low levels of stress when depression levels in the unit were low and increased stress when depression levels were high.

Abstract
PURPOSE Psychosocial stress has been related to impaired immunity in cancer patients. However, the extent to which these relationships exist in immune cells in the tumor microenvironment in humans has not been explored. We examined relationships among distress, social support, and natural killer (NK) cell activity in ovarian cancer patients in peripheral-blood mononuclear cells (PBMC), ascitic fluid, and tumor-infiltrating lymphocytes (TIL). PATIENTS AND METHODS Patients awaiting surgery for a pelvic mass suspected of being ovarian cancer completed psychological questionnaires and gave a presurgical sample of peripheral blood. Samples of tumor and ascites were taken during surgery, lymphocytes were then isolated, and NK cytotoxicity and percentage were determined. The final sample, which was confirmed by surgical diagnosis, included 42 patients with epithelial ovarian cancer and 23 patients with benign masses. RESULTS Peripheral NK cell activity was significantly lower among ovarian cancer patients than in patients with benign masses. Among ovarian cancer patients, NK cytotoxicity in TIL was significantly lower than in PBMC or ascitic fluid. Social support was related to higher NK cytotoxicity in PBMC and TIL, adjusting for stage. Distress was related to lower NK cytotoxicity in TIL. A multivariate model indicated independent associations of both distress and social support with NK cell activity in TIL. CONCLUSION Psychosocial factors, such as social support and distress, are associated with changes in the cellular immune response, not only in peripheral blood, but also at the tumor level. These relationships were more robust in TIL. These findings support the presence of stress influences in the tumor microenvironment.

Abstract
There is clinical and experimental evidence that the brain can start, influence, and stop biologic skin events. Studies suggest that the skin, as a relevant part of the "diffuse brain," can modify the quality of perceptions and feelings. The immune and the endocrine systems seem to represent the protagonists of the modulation of those events and, in this context, psychosocial stressors and interventions can lead to global health changes of great interest for dermatologists.

Abstract
BACKGROUND Expressive emotional writing has demonstrated efficacy for improving health status in a wide variety of healthy persons and recently in patients with chronic disease. PURPOSE This study was a randomized, controlled effectiveness trial with 4 arms: 2 active treatment writing groups, 1 inactive writing group, and 1 attention control group. It represents the first attempt to translate the expressive writing intervention into a low-cost, community-based intervention in the form of a videotaped program. METHODS Feasibility of the approach and patient adherence were examined in a community rheumatology practice with rheumatoid arthritis patients (N = 373). RESULTS The videotape format was able to convey the intervention instructions accurately and produced the expected and differential ratings of stressfulness and emotional provocation across the 3 writing programs. Seventy-nine percent of eligible patients agreed to take the program home; 49% of these patients reported that they followed the protocol. Physician Disease Activity Rating and the Physical Component Summary of the SF36v2 Health Survey were assessed pre and post program. CONCLUSIONS Intent-to-treat analyses found no effect of the treatment. Pretreatment differences among the protocol-adherent patients complicated treatment outcome interpretation. The standard writing instructions did not yield an effect; a modified set of instructions to extract meaning from the traumatic event yielded equivocal results. Contrasts between efficacy and effectiveness trials and the challenge of achieving significant outcomes in effectiveness trials are discussed.

Abstract
The purpose of this paper is the exploration and explication of the complex phenomena of "healing presence" and of appropriately supportive theoretical approaches to integrate emerging models for research design. Healing presence is described as an interpersonal, intrapersonal, and transpersonal to transcendent phenomenon that leads to a beneficial, therapeutic, and/or positive spiritual change within another individual (healee) and also within the healer. An integrated framework merging knowledge from diverse fields of research develops the multiple elements of healing presence, the healer, the healee's capacity for response and the healing effect as an entangled phenomenon. A conceptual systemic model is presented, and questions and dilemmas that emerge are delineated. An integrated qualitative-quantitative research design is proposed. A systemic relationship model, which includes the healer, the healee, and persons within the healee's environment is presented. The challenges are substantial, but the research questions are meaningful and worthwhile. The goal is to foster healing at bio-psycho-social-spiritual levels of the human being.

Abstract
Previously we demonstrated that stressors varying on the dimension of mental effort and controllability have distinctive effects on cardiovascular, endocrine and immune system responses. The purpose of the present study was to relate individual differences in physiological stress responsivity to task appraisal and stress-induced mood changes (issue 1), trait characteristics (issue 2) and daily hassles (issue 3). Appraisal and mood changes did not mediate the differential effects of the stressors. The trait characteristics, aggression and external locus of control and daily hassles moderated the effect of the stressor on physiological parameters, especially immune parameters. Moreover, the moderation effect was different in the high versus the low effort stress task. High aggression, high external locus of control and more daily hassles were associated with increased reactivity in the low effort condition and decreased reactivity in the high effort condition, which is suggested to reflect less differentiated responding to changing task demands and hence, less flexibility in the immune system.

Abstract
This study examined three theoretical models of hostility, health and life context. According to the psychosocial vulnerability hypothesis, there is an interaction between hostility and adverse conditions. The increased health risk in hostile individuals is assumed to stem from their lower ability to benefit from existing psychosocial resources. The second hypothesis, called here the social context model, considers adverse conditions as an antecedent of both hostility and health problems. The third model states that hostility is a predictor of being selected to adverse conditions involving risk to health (the selection hypothesis). The results from a survey of a population-based random sample (2153 non-institutionalized citizens aged 18-64 years) in Finland, showed that hostile men had a high prevalence of non-optimal health, irrespective of employment status. In non-hostile men, employment was associated with better health than unemployment. This association between hostility and unemployment was not found in women. Corresponding findings were obtained from a 1959-born cohort of 311 individuals followed up for 27 years. The combination of high hostility at school age and unemployment in adulthood had an additive effect on poor health in adult men but not in adult women. Hostility in childhood was not significantly associated with unemployment in adulthood. Thus, this study supported the psychosocial vulnerability model in men.

Abstract
OBJECTIVE This study examined the relationship between emotional expression and depth processing of trauma and long-term survival of patients living with AIDS. A further purpose was to examine the immune, health behavior and psychosocial correlates of emotional disclosure and depth processing. METHOD Subjects wrote essays describing their reactions to past traumas; these were scored for emotional expression and depth processing (positive cognitive appraisal change, experiential involvement, self-esteem enhancement and adaptive coping strategies). Two HIV-seropositive groups were recruited for this study; long-term survivors (LTS; n=46) patients who had survived at least 4 years past a Category C (AIDS defining) symptom prior to starting protease inhibitors and an equivalent HIV-seropositive comparison group (ECOMP(LTS); n=89) who had CD4+ cells between 150 and 500, and had no history of Category C symptoms. The groups were equivalent on age, gender, ethnicity, education, employment, income, sexual orientation and route of infection. RESULTS The group LTS were significantly higher than the ECOMP(LTS) group on emotional expression and depth processing. Depth processing mediated the relationship between emotional expression and long-term survival status. Depth processing was positively related to CD4+ cell number for women. Emotional expression was also significantly related to viral load (negatively) and to CD4+ cell number (positively) for women only. Interestingly, only depth processing (and not emotional expression) was related to medication adherence and to psychosocial variables (perceived stress and social support). CONCLUSIONS Emotional expression and depth processing were related to long-term survival, however, depth processing was the mediator for this relationship and only depth processing was associated with medication adherence, perceived stress and social support. Our results underscore the importance of depth processing (and not just emotional expression) of traumatic experiences for people living with HIV/AIDS.

Abstract
OBJECTIVE This cross-sectional study examined the hypothesis that the capacity for emotional expression is a critical moderator of the emotional support-health relationship. METHODS In a sample of 61 HIV-seropositive women without AIDS, coping interviews were conducted to assess HIV-specific emotional support and emotional expression and inhibition (percentage of positive/negative emotion words and inhibition words, respectively). RESULTS Hierarchical regression analyses revealed no relationship between availability of HIV-specific emotional support and concurrent CD4 levels and no moderation of emotional expression or inhibition. However, a higher percentage of inhibition words was associated with lower CD4 T-cell levels controlling for health behaviors, demographics, and treatment regimen (DeltaR(2)=.08, P<.05). CONCLUSIONS These findings are consistent with prior theory and research showing a relationship between psychological inhibition and deleterious health outcomes.

Abstract
In this article, the authors evaluate the possible roles of negative emotions and cognitions in the association between socioeconomic status (SES) and physical health, focusing on the outcomes of cardiovascular diseases and all-cause mortality. After reviewing the limited direct evidence, the authors examine indirect evidence showing that (a) SES relates to the targeted health outcomes, (b) SES relates to negative emotions and cognitions, and (c) negative emotions and cognitions relate to the targeted health outcomes. The authors present a general framework for understanding the roles of cognitive-emotional factors, suggesting that low-SES environments are stressful and reduce individuals' reserve capacity to manage stress, thereby increasing vulnerability to negative emotions and cognitions. The article concludes with suggestions for future research to better evaluate the proposed model.

Abstract
Aggression, hostility, and anger significantly predict morbidity and mortality from atherosclerotic cardiovascular disease (ACVD). ACVD is believed to be an inflammatory disease characterized by increased expression of a number of proinflammatory cytokines, such as tumor necrosis factor (TNF)-alpha. This study examined the relation of aggression, hostility, and anger to monocyte-associated TNF-alpha expression following lipopolysaccharide (LPS) stimulation. Participants were 62 healthy, non-smoking men (aged 18-45 years). Hostility, anger, verbal, and physical aggression were assessed using the Buss-Perry aggression questionnaire (BPAQ). LPS-stimulated TNF-alpha expression was determined using dual-color flow cytometry gating for CD14(+) cells. After controlling for age, race, education, and alcohol use, scores on the hostility (p=.013), physical aggression (p=.010), and verbal aggression (p=.034) subscales, and the total score (p=.007) on the BPAQ were positively associated with LPS-stimulated TNF-alpha expression. The results suggest that hostility and aggression are associated with an increased expression of TNF-alpha, a cytokine implicated in ACVD.

Abstract
This review focuses on human psychoneuroimmunology studies published in the past decade. Issues discussed include the routes through which psychological factors influence immune function, how a stressor's duration may influence the changes observed, individual difference variables, the ability of interventions to modulate immune function, and the health consequences of psychosocially mediated immune dysregulation. The importance of negative affect and supportive personal relationships are highlighted. Recent data suggest that immune dysregulation may be one core mechanism for a spectrum of conditions associated with aging, including cardiovascular disease, osteoporosis, arthritis, Type 2 diabetes, certain cancers, and frailty and functional decline; production of proinflammatory cytokines that influence these and other conditions can be stimulated directly by negative emotions and indirectly by prolonged infection.

Abstract
Negative emotions can intensify a variety of health threats. We provide a broad framework relating negative emotions to a range of diseases whose onset and course may be influenced by the immune system; inflammation has been linked to a spectrum of conditions associated with aging, including cardiovascular disease, osteoporosis, arthritis, type 2 diabetes, certain cancers, Alzheimer's disease, frailty and functional decline, and periodontal disease. Production of proinflammatory cytokines that influence these and other conditions can be directly stimulated by negative emotions and stressful experiences. Additionally, negative emotions also contribute to prolonged infection and delayed wound healing, processes that fuel sustained proinflammatory cytokine production. Accordingly, we argue that distress-related immune dysregulation may be one core mechanism behind a large and diverse set of health risks associated with negative emotions. Resources such as close personal relationships that diminish negative emotions enhance health in part through their positive impact on immune and endocrine regulation.

Abstract
OBJECTIVE Although psychological modulation of immune function is now a well-established phenomenon, much of the relevant literature has been published within the last decade. This article speculates on future directions for psychoneuroimmunology research, after reviewing the history of the field. METHODS This review focuses on human psychoneuroimmunology studies published since 1939, particularly those that have appeared in Psychosomatic Medicine. Studies were clustered according to key themes, including stressor duration and characteristics (laboratory stressors, time-limited naturalistic stressors, or chronic stress), as well as the influences of psychopathology, personality, and interpersonal relationships; the responsiveness of the immune system to behavioral interventions is also addressed. Additionally, we describe trends in populations studied and the changing nature of immunological assessments. The final section focuses on health outcomes and future directions for the field. RESULTS There are now sufficient data to conclude that immune modulation by psychosocial stressors or interventions can lead to actual health changes, with the strongest direct evidence to date in infectious disease and wound healing. Furthermore, recent medical literature has highlighted a spectrum of diseases whose onset and course may be influenced by proinflammatory cytokines, from cardiovascular disease to frailty and functional decline; proinflammatory cytokine production can be directly stimulated by negative emotions and stressful experiences and indirectly stimulated by chronic or recurring infections. Accordingly, distress-related immune dysregulation may be one core mechanism behind a diverse set of health risks associated with negative emotions. CONCLUSIONS We suggest that psychoneuroimmunology may have broad implications for the basic biological sciences and medicine.

Abstract
We examined lymphocyte responses to mitogens [phytohemagglutinin (PHA), concanavalin A, pokeweed] in spouse caregivers of persons with Alzheimer's disease (n = 82; mean age = 69.4) and noncaregiver spouses (n = 83) group matched on age and gender. Data were collected at study entry (T1) and 15-18 months later (T2). In men (n = 52), a depressed mood factor was negatively related to all mitogen responses at T1 and PHA at T2. Loneliness was the most important variable in the depressed mood factor. No relationships occurred in women (n = 113). At T2 an anger expression factor (anger-out--anger-control) was negatively related to all mitogen responses in caregivers. Anger-out was the most important variable for anger expression. Depressed mood at T1 predicted residualized changes in PHA at T2 in men. In conclusion, men with higher depressed mood and caregivers with higher anger expression may be at risk for lower proliferation responses.

Abstract
OBJECTIVE This study examined the effects of pain and stress associated with a dental procedure, root canal treatment (RCT), on natural killer cell cytotoxicity (NKCC) and the subsequent development of symptoms of upper respiratory illness during the following month. METHODS Patients (N = 33) were recruited from those scheduled for RCT appointments. Subjects for a non-RCT comparison group (N = 14) were also recruited from dental clinic patients. Peripheral blood was drawn by use of an indwelling catheter three times: just before RCT, 30 minutes after injection of a local anesthetic, and 30 minutes after RCT (a parallel time course was followed for the comparison group.) Blood was assayed for cortisol and NKCC. Subjects completed a health diary in the month after RCT. RESULTS Patients showed a significant increase in NKCC between baseline and RCT and a significant decrease from RCT to after RCT, whereas the comparison group did not. The NKCC following the RCT was negatively correlated with the pain level during RCT (r = -0.48, p < .01) and pain levels 2 and 6 hours after RCT (r = -0.43, p < .05; r = -0.44 p < .05, respectively). The patient group reported significantly more illness episodes 2 weeks after RCT than the comparison group (Wilcoxon rank sum = 4.78, p = .03). Discriminant function analysis correctly classified 88% of the subjects into the illness category using predictor variables of post-RCT NKCC, stress, and pain levels during RCT (F(3,21) = 8.23, p < .001). CONCLUSIONS Transitory changes in NKCC associated with pain and stress may be implicated in the development of infectious disease episodes after an acute stressful event.

Abstract
A relationship between personality and the immune system has been hypothesized for at least 25 years, and understanding this relationship could contribute to understanding how personality affects the onset and course of chronic diseases such as cancer and heart disease. A number of personality dimensions, including repression, optimism, hostility, attributional style, and extraversion-introversion, have been related to immune parameters or immunity. Theoretical and methodological issues in interpreting the extant literature and in planning future research include selection of personality dimensions to study, study design, and attention to potential psychosocial mediators. Past and future investigations using sophisticated theory and methodology to investigate the ongoing influence of personality on physiological systems, including the immune system, promise to advance the understanding of both.

Abstract
BACKGROUND The psychological and physical response to moderate life stressors among older adults has not been well characterized. This research examines effects of voluntary housing relocation on distress and immune function in healthy older adults as a model for studying the effects of moderate life stress. METHODS Thirty older adults moving to congregate living facilities were assessed 1 month premove, 2 weeks postmove, and 3 months postmove. Twenty-eight nonmoving control subjects were assessed at similar time points. Subjects completed psychosocial questionnaires and had early morning blood draws in their homes. Blood samples were assayed for natural killer cell cytotoxicity (NKCC), interleukin-6 (IL-6), and IgG antibody titers to the Epstein Barr virus (EBV) viral capsid antigen. RESULTS Movers demonstrated decreased vigor and elevated thought intrusion 1 month premove and 2 weeks postmove. By the 3-month follow-up, vigor increased, and intrusion decreased to levels commensurate with the controls. Averaged across all time points, movers showed lower NKCC than controls; however, post-hoc analyses indicate that by the 3-month follow-up time point, these differences were no longer significant. There were no differences between groups in IL-6 or in EBV antibody titers. Independent of the effects of group, higher levels of vigor were associated with greater NKCC at all assessments and with lower EBV titers at 2 weeks postmove. CONCLUSIONS Findings suggest that in general, healthy older adults recover well psychologically from moderate. temporary life stressors such as moving. Whereas movers showed generally lower NKCC than controls, IL-6 and EBV antibody titers appeared not to be strongly affected by the stress of moving.

Abstract
This article reviews evidence for the hypothesis that psychological interventions can modulate the immune response in humans and presents a series of models depicting the psychobiological pathways through which this might occur. Although more than 85 trials have been conducted, meta-analyses reveal only modest evidence that interventions can reliably alter immune parameters. The most consistent evidence emerges from hypnosis and conditioning trials. Disclosure and stress management show scattered evidence of success. Relaxation demonstrates little capacity to elicit immune change. Although these data provide only modest evidence of successful immune modulation, it would be premature to conclude that the immune system is unresponsive to psychological interventions. This literature has important conceptual and methodological issues that need to be resolved before any definitive conclusions can be reached.

Abstract
OBJECTIVES To evaluate in a group of physicians the relation between burnout, demographic or job characteristics, anxiety, and immune variables. METHODS Seventy one physicians of all grades were recruited among different departments to a cross sectional survey. The Maslach burnout inventory, scales of emotional exhaustion, depersonalisation, and personal accomplishment, the trait scale of anxiety inventory (STAI-Y2), and a questionnaire on personal and professional characteristics were administered. The immune profile included quantitative (number (%) of lymphocytes and subsets) and functional (natural killer cytotoxicity) measures. RESULTS With a model of stepwise multiple regression analysis, emotional exhaustion was significantly affected by both personal (marital, sex) and job characteristics (qualification, working activity), whereas only patient contact explained a portion of variation in depersonalisation. Furthermore, trait anxiety was found to predict the Maslach burnout inventory scores. After correction for potential confounders, physicians who scored high levels of personal accomplishment showed significantly higher numbers of total lymphocytes, T cells (CD3), T helper cells (CD4), and T suppressor cells (CD8) than those who scored low levels. No other correlation was found between burnout and immune variables. CONCLUSIONS In our group of relatively young physicians a high degree of personal accomplishment was associated with an increase in the number of peripheral lymphocytes, particularly T subsets. The meaning of this is not clear, although it could be speculated that to evaluate oneself positively, particularly with regard to work with patients in the health services, might help to stimulate the immune system. By contrast, there is no evidence that to work hard, to feel tired from work, and to have a cynical reaction towards patient care is related to immunosuppression.

Abstract
In this chapter, we examine the possibility that negative emotions contribute to the relationship between socioeconomic status (SES) and health. A model of the associations among SES, emotion, and health is presented first. We then review the evidence for this model, showing associations of SES with depression, hopelessness, anxiety, and hostile affect and cognition, and of these negative emotions with disease. Notably, most of the data supporting the model provide only indirect evidence that negative emotions serve as a key contributor to the proposed associations. We, therefore, conclude with recommendations for longitudinal research, especially in children, that will more directly and comprehensively examine negative emotions as possible mediators of the SES and health relationship.

Abstract
OBJECTIVE The purpose of this study was to examine the extent to which increased risk to health problems in hostile employees is associated with psychosocial resources and life context. METHODS Social relationships, job control, and sickness absence were assessed among 757 hostile and nonhostile municipal employees in two life contexts: during a stressful organizational downsizing; and during a period after the downsizing. The follow-up time was 550 person-years for men and 1677 person-years for women during the period of downsizing, and 519 person-years for men and 1568 person-years for women during the period after downsizing. RESULTS The risk of sick leave was 1.2-1.4-fold higher in the hostile individuals than in the others. Small network size in hostile employees related to a 1.4-2.5-fold higher risk of sick leave compared to large network size. In nonhostile employees, network size did not associate with sick leave. Poor job control effected a 50% higher risk of sick leave in hostile than in nonhostile individuals during downsizing. During the less stressful period, both hostility and poorjob control increased absence rates independently of one another. Strong spouse support protected only nonhostile employees from sickness. No differences between hostile and nonhostile employees were found in the levels of psychosocial resources or changes in them. CONCLUSION The risk of health problems in hostile persons could be linked with heightened vulnerability in poor psychosocial resource conditions and with the inability to benefit from existing psychosocial resources. Such personal deficits seem to be resource-specific and vary somewhat according to an individual's life context.

Abstract
This study was performed to evaluate the relation between a stable personality trait, a mood state and immune response to an examination stress. A self-reported measure of emotional stability (BFQ-ES scale) was obtained in a sample (n = 39) randomly selected from 277 cadets; this personality trait was also investigated by completing a neuroticism scale (Eysenck personality inventory) and a trait-anxiety scale (STAI). Natural killer (NK) cell activity was measured at baseline, long before the examination time and the examination day. The state-anxiety scale evaluated the response to the stressful stimulus. Taking subjects all together, the academic task did not result in significant modification over baseline in NK cell activity. Subjects were then divided into three groups based on emotional stability and state-anxiety scores: high emotional stability/low anxiety, medium, and low emotional stability/high anxiety. Examination stress induced significant increases in NK cell activity in the high emotional stability/low anxiety group, no effect in the medium group, and significant decreases in the low emotional stability/high anxiety group. The repeated-measure ANOVA revealed a significant interaction of group x period (baseline vs. examination) for both lytic units and percent cytolysis. The results did not change after introducing coffee and smoking habits as covariates. Our findings suggest that the state-anxiety acts in concert with a stable personality trait to modulate NK response in healthy subjects exposed to a psychological naturalistic stress. The relation between anxiety and poor immune control has been already described, whereas the ability of emotional stability to associate with an immunoenhancement has not yet reported. The peculiarity of our population, a very homogeneous and healthy group for life style and habits, can have highlighted the role of emotional stability, and may account for the difference with other studies.

Abstract
Although there is now abundant evidence that certain personality features constitute risk factors for negative health outcomes, personality measures have received little attention to date in the behavioral immunology literature. The present study assessed the relationship between major dimensions of personality and tonic cardiovascular, neuroendocrine, and immunologic parameters in 276 healthy adults. Participants who scored low in agreeableness tended to have higher levels of systolic blood pressure, diastolic blood pressure, and epinephrine. Low levels of extraversion were associated with higher blood pressure, epinephrine, norepinephrine, and natural killer cell cytotoxicity. Neuroticism was generally unrelated to physiologic outcomes. Personality was not associated with leukocyte subset counts. The magnitude of relationships between personality and physiology was modest, with personality measures accounting for 1 to 7% of the variance in selected physiological parameters. Health practices did not mediate associations between personality and physiologic outcomes. However, a substantial proportion of the relationship between extraversion and natural killer cell cytotoxicity was accounted for by their common association with epinephrine and to a lesser extent norepinephrine. These findings are consistent with the notion that personality contributes to basal physiology and provide a foundation for further research on the relationship between personality and natural killer cell cytotoxicity.

Abstract
Recently, a great deal of attention has been focused on the health promoting benefits that can accrue from revisiting painful emotion. The rationales for revisiting painful emotions include those that assume reexperiencing emotion per se can be health-promoting. Another view stipulates that revisiting painful emotion will only yield benefit if there is some recasting/restructuring of the emotional memory. Research pertinent to the various rationales is discussed. Then research on the impact of emotional expression and outcomes studies of therapies designed to enhance emotional experience are reviewed. Good supporting evidence is found for the effectiveness of behavioral exposure therapies where the duration of emotional exposure is carefully controlled, as well as for the salutary impact of talking or writing about trauma by normally functioning individuals. On the other hand, studies evaluating the impact of experiencing and expressing painful emotion in an unstructured fashion with clinical samples suggest that the process can be harmful. Incorporating findings from the behavioral exposure literature and from the Pennebaker writing-about-trauma studies, the case for evoking emotional memories for the purpose of developing new responses is advanced. The dangers of encouraging emotional experience in absence of acquisition of a new response to the emotion-evoking material are discussed.
