Divergent associations of adaptive and maladaptive emotion regulation strategies with inflammation

Cardiovascular Health in the Transition From Adolescence to Emerging Adulthood: A Scientific Statement From the American Heart Association

Cardiovascular disease remains a leading cause of death in the United States, with an alarming rise in the proportion of young adults experiencing cardiovascular events. Many adolescents enter adulthood with significant cardiovascular disease risk factors. This scientific statement addresses the critical need for cardiovascular health promotion during emerging adulthood, a transitional stage between the ages of 18 and 25 or 29 years of age. We discuss the significance of social determinants of health and the interplay between individual-level risk factors and developmental changes, including shifts in substance use, social connections, and emotional well-being. We conclude by outlining strategies for optimizing cardiovascular health promotion and disease prevention, underscoring the importance of primordial prevention, early intervention, and tailored approaches to address the unique needs of emerging adults. Addressing these multifaceted factors is crucial for mitigating the burden of cardiovascular disease risk factors among emerging adults and promoting long-term cardiovascular well-being.

The impact of experimentally instructed suppression on cardiovascular habituation during repeated stress

Experimental research has shown instructed suppression is associated with heightened physiological responses during a single active stress exposure, with heightened responses to stress being a potential underlying mechanism linking suppression to cardiovascular disease (CVD). However, no research to date has examined instructed suppression with cardiovascular habituation to repeated stress. This study extends prior research by introducing a novel experimental paradigm, which incorporates a traditional suppression manipulation protocol within an active stress habituation framework. Between September 2022 and May 2023, participants (N = 244; mean (SD) age = 19.04 (1.9) years; 50.4 % women; 65.6 % White) completed a 10-min baseline, 5-min speech preparation, and 5-min speech delivery, which was repeated after a 10-min recovery. Participants were randomly assigned to either suppression or control instructions before the second speech prep. Heart rate (HR), systolic/diastolic blood pressures (SBP/DBP), and pre-ejection period (PEP) were measured throughout. State affect, perceived psychological stress, and state suppression were self-reported after each task. Habitual use of suppression was assessed using the Emotion Regulation Questionnaire. All participants exhibited significant cardiovascular habituation, irrespective of condition, suggesting instructed suppression did not hinder habituation. Instructed suppression was not associated with changes in perceived psychological stress or positive affect across tasks; however, instructed suppression was associated with greater habituation of negative affect. Neither state nor habitual suppression interacted with instructed suppression in influencing task responses. This is the first study to examine the relationship between experimentally instructed suppression and cardiovascular habituation, providing new perspective of the interplay between suppression and cardiovascular stress responding.

Early adversity and inflammation at midlife: the moderating role of internalizing psychopathology

BACKGROUND

Childhood adversity has been associated with increased peripheral inflammation in adulthood. However, not all individuals who experience early adversity develop these inflammatory outcomes. Separately, there is also a link between various internalizing emotional distress conditions (e.g. depression, anxiety, and fear) and inflammation in adulthood. It is possible the combination of adult emotional distress and past childhood adversity may be uniquely important for explaining psychopathology-related immune dysfunction at midlife.

METHODS

Using data from the Midlife in the United States (MIDUS) study (n = 1255), we examined whether internalizing, defined as past 12-month emotional distress symptomatology and trait neuroticism, moderated associations between childhood adversity and heightened inflammation in adulthood. Using latent variable modeling, we examined whether transdiagnostic or disorder-specific features of emotional distress better predicted inflammation.

RESULTS

We observed that childhood adversity only predicted adult inflammation when participants also reported adult internalizing emotional distress. Furthermore, this moderation effect was specific to the transdiagnostic factor of emotional distress rather than the disorder-specific features.

CONCLUSIONS

We discuss the possibility that adult internalizing symptoms and trait neuroticism together may signal the presence of temporally stable vulnerabilities that amplify the impact of childhood adversity on midlife immune alterations. The study highlights the importance of identifying emotional distress in individuals who have experienced childhood adversity to address long-term immune outcomes and enhance overall health.

Emotion suppression differentially moderates the link between stress and cardiovascular disease risk in Japanese and Americans

Background

Cardiovascular disease (CVD) remains a key cause of mortality worldwide. Prior work has found that the association between stress and cardiovascular outcomes is moderated by emotion regulation (ER) and expressive suppression (i.e., emotion inhibition), which is linked with adverse outcomes (i.e., inflammation) in Western (Americans) but not Eastern (Japanese) populations. Existing cultural differences in biological stress responses and suppression use suggest that these factors may have different implications for CV outcomes.

Objective

We address this gap in the literature by examining if ER differentially moderates the relationship between stress and CVD risk between Japanese and American adults.

Method

Participants were from the Midlife in Japan and Midlife in the United States studies and had complete biomarker and psychological data (Japanese: N = 315, M age = 59.22, 149 females; Americans: N = 524, M age = 51.98, 291 females). Stress was indexed using the perceived stress scale. Trait suppression and reappraisal were indexed using the Emotion Regulation Questionnaire. CVD risk was indexed using a composite score of body mass index, C-reactive protein, interleukin-6, systolic blood pressure, and high-density lipoprotein cholesterol ratio.

Results

Adjusting for age, sex, education, tobacco, alcohol, and prescription medication use, linear regressions revealed robust cultural differences among those with high suppression (r = -0.10 [-0.19, -0.01]). Higher stress was linked with higher CVD risk in Americans regardless of the level of reappraisal or suppression (r's > 0.11, p's < 0.07). In contrast, among Japanese with high suppression, higher stress was associated with lower CVD risk (r = -0.09 [-0.23, 0.05]). Higher stress was associated with greater inflammation among Japanese with lower suppression (r = 0.10 [-0.07, 0.28]).

Conclusions

Consistent with prior work, these findings suggest that adaptive ER moderates the association between stress and CVD risk, and that suppression may not be universally 'maladaptive.' Results emphasize the importance of considering cultural context when assessing the impact of emotion suppression on health, which may help explain differences in CVD outcomes between individuals from Eastern and Western populations.

Affective predictors of social support in individuals with schizophrenia

BACKGROUND

Social Support has been found to contribute to lower mental illness burden, higher treatment adherence, enhanced social functioning, and better quality of life. Individuals with schizophrenia report lower social support compared to non-clinical populations, yet the factors contributing to this discrepancy are not fully clear. Specifically, the person-related variables that may enhance or hinder SS in people with schizophrenia are unknown. Evidence from affective neuroscience research has implicated emotion awareness and regulation as key predictors of social functioning, a correlate of social support. However, their potential impact on social support in schizophrenia has not been investigated.

METHODS

We examined emotion awareness, emotion regulation and social support in 90 individuals with schizophrenia and 26 healthy controls.

RESULTS

The schizophrenia group reported significantly poorer emotion awareness, more frequent use of suppression to regulate emotions, as well as lower social support. Within the schizophrenia group, results from mediation analyses pointed to significant indirect effects of specific emotion regulation strategies on social support through emotion awareness, with use of suppression predicting lower social support via decreased emotion awareness, and conversely, use of cognitive reappraisal predicting greater social support via increased emotion awareness. Notably, emotion awareness was more strongly associated with social support from friends than from family members.

CONCLUSIONS

The results highlight poor emotion awareness as a key variable critical to enhancing social support in people schizophrenia. We discuss potential mechanisms underlying the links between emotion awareness, emotion regulation, and SS, along with the therapeutic implications of the findings.

Examining the association between habitual emotion regulation strategies and cardiovascular stress reactivity across three studies

Poor emotion regulation is associated with cardiovascular disease risk, with altered cardiovascular responses to psychological stress a possible underlying mechanism. However, prior research has predominantly focused on instructed (laboratory-based) emotion regulation; there is limited conclusive research on the relationship between every-day (habitual) emotion regulation and cardiovascular responses to active psychological stress. As such, this study aimed to examine the associations between two common habitual emotion regulation strategies-cognitive reappraisal and expressive suppression-and cardiovascular stress responses across three independent laboratory studies, each involving a different active acute psychological stress task. Participants (Study 1: N = 239, 64.9 % female; Study 2: N = 289, 51.9 % female, Study 3: N = 169, 50.9 % female) underwent cardiovascular monitoring during a 10-min baseline and subsequent stress task (Study 1: mental arithmetic task; Study 2: speech task; Study 3: Multisource Interference/Stroop tasks). Participants also completed the Emotion Regulation Questionnaire and ratings of perceived task stressfulness. Cardiovascular reactivity (stress mean - baseline mean) was calculated for systolic/diastolic blood pressure and heart rate for each study. Across all three studies, regression analyses demonstrated no statistically significant linear associations between habitual emotion regulation and cardiovascular reactivity (ps ≥ .10) or self-reported perceived stress (ps ≥ .06), both before and after controlling for demographic covariates. This investigation furthers our understanding of how habitual emotion regulation strategies may-or may not-impact cardiovascular stress responses, thus providing valuable insights into the complex relationship between emotion regulation and long-term cardiovascular health.

Interplay Between Health-Promoting Lifestyle, and Cognitive Emotion Regulation with Risk of Cosmetic Surgery Seeking in Young Women

OBJECTIVES

This study investigated the relationship between lifestyle and cognitive regulation of emotion and the risk of seeking cosmetic surgery in young women.

METHODS

The current study was a cross-sectional study. The outcome variable in this research was cosmetic surgery seeking. The association between sociodemographic and health behaviors with risk of cosmetic surgery seeking investigated. The multinomial logistic regression was used to examine the association between health promotion lifestyle and cognitive emotion regulation with cosmetic surgery seeking.

RESULTS

Underweight was associated with cosmetic surgery seeking [5.50; 95% CI 1.90-15.92; P<0.005]. Other risk factors were former smoking, alcohol use, and poor sleep quality. An increase in poor lifestyle is associated with an increased risk of cosmetic surgery seeking [30.41; 95% CI 4.87-189.84; P<0.001]. Adaptive cognitive emotion regulation protects against cosmetic surgery seeking [0.36; 95% CI 0.15-0.84; P<0.001].

DISCUSSION

Lifestyle and adaptive cognitive emotion regulation played a significant role in people who were looking for cosmetic surgery, and therefore, like in other areas of disease and health, lifestyle and adaptive cognitive emotion regulation are important in cosmetic surgery, and it is necessary to pay attention to the effects of each of them.

Investigating the psychometric properties of pathological concern questionnaire in Indian emerging adults

Background

The Pathological Concern Questionnaire (PCQ) measures thoughts, emotions, and actions based on attitudes, including repression of personal needs and overinvestment in satisfaction of others' needs. The PCQ is widely used in the literature, but its psychometric properties are not well-established in the Indian population.

Aim

The current study aimed to examine the reliability and validity of PCQ among emerging adults in India.

Materials and Methods

The data were collected from 252 emerging adults, aged between 18 and 29 years using PCQ. Confirmatory factor analysis was conducted to analyse the data. Internal reliability was computed using Cronbach's alpha and correlational analysis was conducted to examine the convergent and discriminant validity.

Results

The statistical findings supported an acceptable goodness of fit for PCQ in India. PCQ showed an adequate internal consistency (α = 0.903). In addition, correlational analyses supported the convergent and discriminant validity of the PCQ.

Conclusion

Our findings suggest that the PCQ is a valid and reliable instrument to measure pathological concern among Indian emerging adults.

Assessing ChatGPT as a Medical Consultation Assistant for Chronic Hepatitis B: Cross-Language Study of English and Chinese

BACKGROUND

Chronic hepatitis B (CHB) imposes substantial economic and social burdens globally. The management of CHB involves intricate monitoring and adherence challenges, particularly in regions like China, where a high prevalence of CHB intersects with health care resource limitations. This study explores the potential of ChatGPT-3.5, an emerging artificial intelligence (AI) assistant, to address these complexities. With notable capabilities in medical education and practice, ChatGPT-3.5's role is examined in managing CHB, particularly in regions with distinct health care landscapes.

OBJECTIVE

This study aimed to uncover insights into ChatGPT-3.5's potential and limitations in delivering personalized medical consultation assistance for CHB patients across diverse linguistic contexts.

METHODS

Questions sourced from published guidelines, online CHB communities, and search engines in English and Chinese were refined, translated, and compiled into 96 inquiries. Subsequently, these questions were presented to both ChatGPT-3.5 and ChatGPT-4.0 in independent dialogues. The responses were then evaluated by senior physicians, focusing on informativeness, emotional management, consistency across repeated inquiries, and cautionary statements regarding medical advice. Additionally, a true-or-false questionnaire was employed to further discern the variance in information accuracy for closed questions between ChatGPT-3.5 and ChatGPT-4.0.

RESULTS

Over half of the responses (228/370, 61.6%) from ChatGPT-3.5 were considered comprehensive. In contrast, ChatGPT-4.0 exhibited a higher percentage at 74.5% (172/222; P<.001). Notably, superior performance was evident in English, particularly in terms of informativeness and consistency across repeated queries. However, deficiencies were identified in emotional management guidance, with only 3.2% (6/186) in ChatGPT-3.5 and 8.1% (15/154) in ChatGPT-4.0 (P=.04). ChatGPT-3.5 included a disclaimer in 10.8% (24/222) of responses, while ChatGPT-4.0 included a disclaimer in 13.1% (29/222) of responses (P=.46). When responding to true-or-false questions, ChatGPT-4.0 achieved an accuracy rate of 93.3% (168/180), significantly surpassing ChatGPT-3.5's accuracy rate of 65.0% (117/180) (P<.001).

CONCLUSIONS

In this study, ChatGPT demonstrated basic capabilities as a medical consultation assistant for CHB management. The choice of working language for ChatGPT-3.5 was considered a potential factor influencing its performance, particularly in the use of terminology and colloquial language, and this potentially affects its applicability within specific target populations. However, as an updated model, ChatGPT-4.0 exhibits improved information processing capabilities, overcoming the language impact on information accuracy. This suggests that the implications of model advancement on applications need to be considered when selecting large language models as medical consultation assistants. Given that both models performed inadequately in emotional guidance management, this study highlights the importance of providing specific language training and emotional management strategies when deploying ChatGPT for medical purposes. Furthermore, the tendency of these models to use disclaimers in conversations should be further investigated to understand the impact on patients' experiences in practical applications.

Affect variability and cortisol in context: The moderating roles of mean affect and stress

Positive and negative affect have been shown to have implications for hormones like cortisol but how moment to moment changes in affect (i.e., affect variability) influence cortisol secretion is less well understood. Additionally, context characteristics such as mean affect and stress may influence the association between affect variability and cortisol output. In the current study, we examined affect, stress, and cortisol data from 113 participants (age range = 25-63, M = 35.63, SD = 11.34; 29% male; 42% White/Caucasian, 37% Asian or Pacific Islander, 13% Hispanic/Latino, 4% Black/African American, 1% Native American, Eskimo, or Aleut, 4% selected "other" for their race/ethnicity). Participants completed ecological momentary assessments assessing positive and negative affect and stress four times per day for five days and provided saliva samples at each time point. Saliva was assayed for cortisol, and area under the curve with respect to ground was computed. In a three-way interaction, both positive affect mean level and stress moderated the association between positive affect variability and cortisol (b = -1.55, t(100) = -3.29, SE = 0.47, p <.01, β = -4.05). When breaking down this three-way interaction, in the context of low stress and high mean positive affect, variability was positively related to total cortisol output. In contrast, in the context of high stress and high mean positive affect, variability was negatively related to total cortisol output. While greater positive affect variability is generally worse for health-relevant outcomes (as prior research has shown and as we show here at low levels of stress), at high levels of stress, fluctuation in affect may be adaptive. For someone experiencing a high stress week, having fluctuations in positive affect may mean that they are adaptively changing to meet their environmental needs especially when they typically report high mean positive affect levels. There were no associations between negative affect variability and cortisol secretion nor did mean negative affect or stress play a moderating role for negative affect variability. This study provides evidence that positive affect variability's association with cortisol secretion throughout the day may vary based on stress and mean positive affect levels.

Moving toward affective immunology: Legacy and future directions

The term "affective immunology" has recently been used to denote a field focused on the interplay between affective processes (including mood states, specific emotions, and regulatory processes) and various aspects of immune function. The overarching goals of this commentary are a) to provide historical underpinnings of this field with a focus on the profound impact of the work of Janice Kiecolt-Glaser, who is further honored in this special issue, b) to review important off-shoots of her legacy work in this domain, and c) to highlight important future directions for the field. Kiecolt-Glaser's work laid much of the foundation for affective immunology, with groundbreaking research related to depression, hostility and dyadic interactions, loneliness, and other affective patterns, often in the context of holistic models, novel experimental designs, and interventions. Her former mentees (and many of their mentees) have carried on her legacy in these domains, in ways that continue to advance appreciation of how affective processes relate to immune function. There are numerous remaining questions for the field to pursue, including better understanding of the role of emotion regulation, emotional reactivity and recovery, restorative processes, affective variability, and developmental and dynamic social processes. Such work will require greater use of longitudinal and within-person approaches and/or examination of processes in daily life, as well as models that account for interactive and reciprocal processes and which integrate behavior, social context, sociocultural factors, individual differences, and other aspects of health. As more work in these domains continues, building on Kiecolt-Glaser's rich legacy, we move toward the emergence of affective immunology as an important subfield in the domain of psychoneuroimmunology, one which will offer more nuanced understanding of the role of affective processes in immune health.

Emotion suppression and acute physiological responses to stress in healthy populations: a quantitative review of experimental and correlational investigations

Emotion suppression may be linked to poor health outcomes through elevated stress-related physiology. The current meta-analyses investigate the magnitude of the association between suppression and physiological responses to active psychological stress tasks administered in the laboratory. Relevant articles were identified through Medline, PsychINFO, PubMed, and ProQuest. Studies were eligible if they (a) used a sample of healthy, human subjects; (b) assessed physiology during a resting baseline and active psychological stress task; and (c) measured self-report or experimentally manipulated suppression. Twenty-four studies were identified and grouped within two separate random effects meta-analyses based on study methodology, namely, manipulated suppression (k = 12) and/or self-report (k = 14). Experimentally manipulated suppression was associated with greater physiological stress reactivity compared to controls (Hg = 0.20, 95% CI [0.08, 0.33]), primarily driven by cardiac, hemodynamic, and neuroendocrine parameters. Self-report trait suppression was not associated with overall physiological stress reactivity but was associated with greater neuroendocrine reactivity (r = 0.08, 95% CI [0.01, 0.14]). Significant moderator variables were identified (i.e., type/duration of stress task, nature of control instructions, type of physiology, and gender). This review suggests that suppression may exacerbate stress-induced physiological arousal; however, this may differ based upon the chosen methodological assessment of suppression.

Szabo Y. Childhood Adversity and Adult Inflammation: Exploring the Mediating Role of Emotion Regulation in the MIDUS II Study

The present study furthers understanding of how childhood adversity connects to inflammation and, in turn, poor health. Using the publicly available Midlife in the United States II (MIDUS II) dataset, we test a recent theoretical model that suggests emotion regulation is a potential mechanism of associations between adversity and inflammation. We examined the indirect effects of various types of adversity (e.g., stressful events, maltreatment, threat, and deprivation) on inflammation via two emotion regulation strategies (i.e., expressive suppression and reappraisal). Participants included 1096 adults without a history of cancer or HIV/AIDS who had completed the initial MIDUS II follow up and a sub-study examining biomarkers. Participants completed self-report measures inquiring about psychosocial factors including stressful life events, childhood trauma, and emotion regulation as well as provided blood samples. Bivariate correlation indicated that multiple forms of childhood adversity were associated with both C-reactive protein and fibrinogen. Deprivation, as measured by a stressful life events scale, was positively associated with both reappraisal and suppression. Tests of indirect effects indicated that deprivation was positively associated with fibrinogen through both emotion regulation strategies, particularly for female participants. Our findings partially support recent theory positing emotion regulation as a pathway through which childhood adversity may impact inflammation in adulthood. Further, deprivation may be particularly critical in understanding how adversity is connected to maladaptive emotion regulation and inflammation. Emotion regulation may be an important treatment target to mitigate the negative impact of childhood adversity on health and well-being.

To reappraise or not to reappraise? Emotion regulation strategies moderate the association of loneliness during COVID-19 with depression and anxiety

BACKGROUND

The COVID-19 pandemic resulted in heightened feelings of loneliness due to lockouts and social restrictions.

OBJECTIVE

In the present study, we examined the association of loneliness during the pandemic with anxiety and depression, while exploring the moderating role of the tendency to use two emotion-regulation strategies (expressive suppression, cognitive reappraisal).

DESIGN

We chose to examine these associations in a sample of older adults, because they faced higher risk for loneliness and health problems during the COVID-19 pandemic.

METHODS

Specifically, 174 Israeli veterans and ex-prisoners of wars from the 1973 Yom Kippur war (mean age = 69) completed self-report scales tapping loneliness, depression, anxiety, and emotion regulation strategies at the beginning of the COVID-19 outbreak (April-May 2020).

RESULTS

Findings revealed a stronger association between loneliness and depression among participants who had a greater tendency of using suppression. The tendency to use suppression did not significantly moderate the link between loneliness and anxiety. Additionally, a weaker association between loneliness and depression was found among participants who has a greater tendency of using reappraisal. However, these participants showed a stronger association between loneliness and anxiety.

CONCLUSIONS

These findings highlight the complexity of reappraisal and adds to the growing body of work on emotion regulation.

A study of the mediating effect of social support on self-disclosure and demoralization in Chinese older adult homebound breast cancer patients

Purpose

Demoralization is common in older adult homebound breast cancer patients, seriously affecting their quality of life. This study aimed to investigate the demoralization of older adult homebound breast cancer patients and to analyse the mediating effects of social support between self-disclosure and demoralization.

Methods

The study enrolled 368 older adult homebound breast cancer patients reviewed in outpatient clinics of three hospitals from January 2022 to August 2023. A questionnaire survey was conducted using the general information questionnaire, the distress disclosure index (DDI), the social support revalued scale (SSRS), and the demoralization scale (DS). Path analysis was conducted to test the hypothesised serial mediation model.

Results

The total scores of self-disclosure, social support, and demoralization were 37 (25-42), 34 (19-48.75), and 46.5 (35-68), respectively. The results indicated a positive correlation between self-disclosure and social support (p < 0.01). In contrast, a statistically significant negative correlation was observed between self-disclosure, social support, and various demoralization dimensions (p < 0.01). Social support played a partial mediation effects between self-disclosure and demoralization, indirect effect =0.6362, SE = -0.591, 95% CI (-0.785 ~ -0.415); Self-disclosure direct effect demoralization, direct effect =0.3638, SE = -0.337, 95% CI (-0.525 ~ -0.144); total effect, SE = -0.929, 95% CI (-0.945 ~ -0.904).

Discussion

Social support a partial mediated between self-disclosure and demoralization in Chinese older adult homebound breast cancer patients. Clinical staff should focus on developing a social support system for Chinese older adult homebound breast cancer patients, encouraging patients to reveal their minds, and providing psychological counselling to enhance self-confidence and rebirth from adversity.

Emotion regulation tendencies and cardiovascular responses to repeated acute psychological stress

Poor emotion regulation has been associated with cardiovascular disease (CVD) through maladaptive cardiovascular responses to psychological stress. However, there has been scant research examining the relationship between emotion regulation and habituation of cardiovascular responses to recurrent stress, which may be more directly applicable to the experience of stress in everyday life. The aims of the current study were to examine the associations between emotion regulation tendencies and cardiovascular stress reactivity, as well as habituation of cardiovascular reactivity across repeated stressors. A sample of 453 participants (mean (SD) age = 19.5 (1.3) years; 62 % women) completed a repeated stress paradigm, which consisted of two 10-minute baselines and two identical 4-minute stress tasks, separated by a 10-minute recovery period. Heart rate (HR) was measured continuously; systolic/diastolic blood pressures (SBP/DBP) were measured every 2 min. At the end of the visit, participants completed the Emotion Regulation Questionnaire (ERQ) and Difficulties in Emotion Regulation Scale (DERS). Results indicate that impulse control difficulties when distressed (a DERS subscale) were significantly associated with blunted SBP, DBP, and HR reactivity to both stressors, as well as impaired HR habituation across the stressors. None of the ERQ subscales (cognitive reappraisal, expressive suppression) were found to be associated with cardiovascular stress reactivity or habituation. The outcomes of this study demonstrate a potential underlying physiological pathway through which impulse control difficulties when distressed may contribute to CVD risk. This study also reveals the importance of extending traditional cardiovascular stress reactivity protocols to include multiple exposures of the same stress task.

Inflammation and emotion regulation: a narrative review of evidence and mechanisms in emotion dysregulation disorders

Emotion dysregulation (ED) describes a difficulty with the modulation of which emotions are felt, as well as when and how these emotions are experienced or expressed. It is a focal overarching symptom in many severe and prevalent neuropsychiatric diseases, including bipolar disorders (BD), attention deficit/hyperactivity disorder (ADHD), and borderline personality disorder (BPD). In all these disorders, ED can manifest through symptoms of depression, anxiety, or affective lability. Considering the many symptomatic similarities between BD, ADHD, and BPD, a transdiagnostic approach is a promising lens of investigation. Mounting evidence supports the role of peripheral inflammatory markers and stress in the multifactorial aetiology and physiopathology of BD, ADHD, and BPD. Of note, neural circuits that regulate emotions appear particularly vulnerable to inflammatory insults and peripheral inflammation, which can impact the neuroimmune milieu of the central nervous system. Thus far, few studies have examined the link between ED and inflammation in BD, ADHD, and BPD. To our knowledge, no specific work has provided a critical comparison of the results from these disorders. To fill this gap in the literature, we review the known associations and mechanisms linking ED and inflammation in general, and clinically, in BD, ADHD, and BD. Our narrative review begins with an examination of the routes linking ED and inflammation, followed by a discussion of disorder-specific results accounting for methodological limitations and relevant confounding factors. Finally, we critically discuss both correspondences and discrepancies in the results and comment on potential vulnerability markers and promising therapeutic interventions.

Adverse Childhood Experiences and Poor Sleep Quality in Older Adults: The Influence of Emotion Regulation

BACKGROUND

Adverse childhood experiences (ACEs) are associated with sleep impairment across the life span, but little is known about modifiable factors that may ameliorate this relationship, such as adaptive emotion regulation (ER) skills.

METHODS

Data were obtained from an online questionnaire completed by a community sample of older adults (N = 278). The questionnaire included the Pittsburgh Sleep Quality Index, an Adverse Childhood Experiences questionnaire, the Cognitive Emotion Regulation Questionnaire (CERQ), and measures of health conditions, and other sample demographics. Moderation analyses were used to examine the interaction between ACEs and 5 adaptive ER skills of CERQ on sleep quality in older adults, while accounting for the effects of age, sex, income, body mass index, and health.

RESULTS

ACEs were significantly associated with worse sleep quality in older adults, and this effect was moderated by positive reappraisal and refocusing on planning (all ps < .05). For individuals reporting greater use of these ER skills, ACEs had no effect on sleep quality, whereas for individuals reporting less frequent use of these ER skills, ACEs were associated with substantially worse sleep quality. This relationship remained significant after accounting for age, sex, income, body mass index, and health conditions in the model.

CONCLUSIONS

The effects of ACEs on sleep quality persist into older age; however, greater use of ER skills that focus on positively reframing negative events and identifying strategies for coping protect against sleep impairment in individuals with higher ACEs.

Do trait-level emotion regulation strategies moderate associations between retrospective reports of childhood trauma and prospective changes in systemic inflammation?

Childhood trauma may confer risk for poorer adult health through changes in systemic inflammation. Emotion regulation may plausibly moderate associations between childhood trauma and adult psychological well-being, but it remains unclear whether moderation effects extend to differences in systemic inflammation. To examine whether childhood trauma and emotion regulation separately and interactively predict prospective changes in C-reactive protein (CRP) and interleukin-6 (IL-6) and whether biopsychosocial factors account for observed associations. Healthy midlife adults (N = 331) retrospectively reported on childhood trauma, current trait-level cognitive reappraisal and expressive suppression, and had their blood drawn. At baseline and then a median of 2.85 years later, 279 of the 331 participants had their blood drawn, body mass index calculated, and reported on health behaviours (smoking, sleep), psychological distress (perceived stress, depressive symptoms), and years of education. Childhood trauma predicted prospective increases in CRP (B = 0.004, p = 0.049), which were partially accounted for by differences in adiposity, psychological distress, and health behaviours. In contrast, cognitive reappraisal predicted prospective decreases in IL-6 (B = -0.007, p = 0.006), which were independent of biopsychosocial influences. Cognitive reappraisal further moderated the association between childhood trauma and prospective changes in IL-6 (B = -0.001, p = 0.012) such that childhood trauma predicted greater IL-6 increases but only among adults lower in cognitive reappraisal (B = 0.006, p = 0.007). There were no main or moderation effects of expressive suppression (ps > 0.05). Cognitive reappraisal may attenuate IL-6 changes over time and may moderate the prospective association between childhood trauma and systemic inflammation in midlife.

A systematic review of associations between emotion regulation characteristics and inflammation

Elevated inflammation is a risk factor for many psychiatric (e.g., depression) and somatic conditions (e.g., rheumatoid arthritis). Inflammation is influenced by psychosocial processes such as emotion regulation. Characterization of which emotion regulation characteristics impact inflammation could help refine psychosocial interventions aimed at normalizing health-harming inflammatory activity for individuals with psychiatric and somatic illnesses. To investigate this issue, we systematically reviewed the literature on associations between a variety of emotion regulation traits and inflammation. Out of 2816 articles identified, 38 were included in the final review. 28 (74%) found that (a) poor emotion regulation is associated with higher inflammation and/or (b) strong emotion regulation skills are associated with lower inflammation. Consistency of results differed as a function of the emotion regulation construct investigated and methodological characteristics. Results were most consistent for studies testing positive coping/social support seeking or broadly defined emotion regulation/dysregulation. Methodologically, studies testing reactivity to a stressor, adopting a vulnerability-stress framework, or using longitudinal data were most consistent. Implications for integrated, transdiagnostic psychoimmunological theories are discussed, as well as recommendations for clinical research.

Life stressors and immune aging: Protective effects of cognitive reappraisal

Stressful life events may accelerate aspects of immune aging, but habitual use of an adaptive emotion regulation strategy, cognitive reappraisal, may attenuate these effects. This study examined whether cognitive reappraisal moderates the associations between life stressor frequency and stressor desirability on aspects of immune aging, including late-differentiated CD8+ T and natural killer (NK) cells and inflammatory markers (IL-6, TNF-α, and CRP), both between and within people in a longitudinal sample of 149 older adults (mean age = 77.8, range: 64-92 years). Participants reported stressful life events, use of cognitive reappraisal, and provided blood semiannually for up to 5 years to assess aspects of immune aging. Multilevel models, adjusted for demographic and health covariates, tested the between-person (stable, trait-like differences) and within-person associations (dynamic fluctuations) among life stressors and reappraisal on immune aging. Experiencing more frequent life stressors than usual was associated with higher levels of late-differentiated NK cells within person, but this effect was accounted for by experiencing health-related stressors. Unexpectedly, experiencing more frequent and less desirable stressors were associated with lower average levels of TNF-α. As expected, reappraisal moderated the associations between life stressors and late-differentiated NK cells between people and IL-6 within people. Specifically, older adults who experienced less desirable stressors but also used more reappraisal had significantly lower proportions of late-differentiated NK cells on average and lower levels of IL-6 within-person. These results suggest cognitive reappraisal may play a protective role in attenuating the effects of stressful life events on aspects of innate immune aging in older adults.

Is there a cost to caring? Dispositional affective empathy interacts with depressive symptoms to predict higher C-reactive protein 8 years later

Affective empathy, including the tendency to vicariously experience the emotions of others, is a highly-valued prosocial trait, but has been previously found to be associated with higher chronic inflammation cross-sectionally and to interact with the levels of depressive symptoms in important social partners. The current study utilized prospective longitudinal data from a nationally representative study of adults in the United States to assess whether dispositional affective empathy interacted with one's own depressive symptoms to predict C-reactive protein (CRP) approximately eight years later. Results revealed that higher ratings of empathy predicted higher CRP, but only among individuals with lower levels of depressive symptoms. Higher depressive symptoms related to greater inflammation regardless of dispositional empathy and perceived stress did not account for observed associations. Taken together, these findings suggest that vicariously experiencing others' emotions may come at a biological cost, which, if sustained, may place individuals at greater risk for inflammatory diseases.

Psychological distress, optimism and emotion regulation among Israeli Jewish and Arab pregnant women during COVID-19

BACKGROUND

Pregnancy is a vulnerable period for women, and it is especially so under the worldwide COVID-19 pandemic. Whereas there is some evidence for distress among pregnant women during the outspread of COVID-19, little is known about the second wave of the pandemic. We therefore sought to examine the contribution of background variables, ethnicity (Jewish, Arab), personal resources (optimism, emotion regulation), and COVID-19-related anxieties to pregnant Israeli women's psychological distress.

METHOD

A convenience sample of 1127 Israeli women was recruited from 5 July to 7 October 2020.

RESULTS

Not having an academic degree, lower economic status, being an Arab woman, poorer physical health, lower levels of optimism and cognitive reappraisal, higher levels of emotion suppression and COVID-19-related anxieties all contributed significantly to greater psychological distress. Finally, ethnicity moderated the relationship between optimism and emotion suppression and the woman's level of psychological distress.

CONCLUSIONS

The findings reveal risk and resilience factors associated with the psychological distress of pregnant women during the second wave of the COVID-19 pandemic and highlight the potentially greater vulnerability of women from a minority group, showing that ethnicity plays a central role in the way personal resources are related to psychological distress at such times.

Emotional and experiential factors that determine civilizational diseases

Background

The effects of adverse childhood experiences may persist in adult life and manifest themselves in various areas of function-ing. The aim of the study was to identify the emotional and experiential factors that determine civilizational diseases and the methods of regulating emotions and functioning in society.

Participants and procedure

The surveyed group was composed of 141 adults. The respondents defined the existence of adverse experiences and their attachment styles in retrospective. The methods of regulating emotions were also measured, as well as the presence of civilizational diseases.

Results

The authors found a correlation between the style of attachment and the traumatic events experienced during the first 18 years of life and the existence of civilizational diseases. Adverse experiences in childhood and attachment styles proved to be predictors of specific social behaviour aimed at regulating emotions.

Conclusions

The results emphasised the importance of the bond with a parent and of traumatic childhood experiences for the future health condition and for the social and emotional functioning. The study demonstrated that persons who experienced traumatic events in their families or in the peer environment in the first 18 years of their lives reported the presence of civilizational diseases. A correlation was found between peer violence, the threat of being abandoned by a caregiver, and diagnosed civilizational diseases in respondents. The fearful-ambivalent style in the relationship with the father proved to be a predictor of reported civilizational diseases. Adverse childhood experiences are linked to regulating emotions by tak-ing perspective. The attachment style developed in the relationship with parents determined the ways of regulating nega-tive and positive emotions in contact with other people. Persons who developed an avoidant attachment style in the rela-tionships with the mother or the father less frequently seek social support when they experience negative emotions.

Investigating measurement invariance of the Emotion Regulation Questionnaire-8 (ERQ-8) across 29 countries

The widely used Emotion Regulation Questionnaire (ERQ) measures the habitual use of cognitive reappraisal and expressive suppression. Recently, a more economical 8-item version of the ERQ was proposed that showed good model fit. We assessed whether the latent constructs of the ERQ-8 are generalizable across different countries and cultures. To this end, we used data from the COVIDiSTRESS survey and investigated measurement invariance of the ERQ-8 in a large sample that included 11,288 individuals from 29 countries with diverse cultural backgrounds. Our analyses revealed configural and metric invariance of the ERQ-8 in 14 countries. The results suggest that emotion regulation strategies may not readily converge across all cultures. This underscores the importance of testing measurement invariance before interpreting observed differences and similarities between countries.

Emotion Regulation Strategies Relate to Ambulatory Cardiovascular Activity in an American Indian Community

OBJECTIVE

Poor emotion regulation is associated with risk for cardiovascular disease. However, much of this research is conducted in primarily White samples, thus limiting our understanding of this relationship in other racial/ethnic groups. American Indians (AIs) are uniquely and disproportionately at risk for cardiovascular disease. As such, the present study aimed to examine the relationships between emotion regulation strategies and ambulatory cardiovascular activity in an entirely AI sample.

METHODS

The sample consisted of 100 AI adults living on a tribal reservation. Emotion regulation strategies (expressive suppression, cognitive reappraisal) were assessed via the Emotion Regulation Questionnaire. Using ecological momentary assessment, daily measurements of psychological stress and ambulatory cardiovascular activity were taken during a 7-day monitoring period. Statistical analyses included bivariate correlations, hierarchical linear regression models, and mediation models.

RESULTS

Expressive suppression was associated with higher systolic and diastolic blood pressure, as well as higher pulse rate. In contrast, cognitive reappraisal was associated with lower systolic and diastolic blood pressure, lower pulse rate, and lower average daily psychological stress. These results remained statistically significant after adjusting for age, sex, body mass index, anxiety, depression, and early life trauma. In addition, psychological stress mediated the associations between blood pressure and cognitive reappraisal, but not expressive suppression.

CONCLUSIONS

These results provide preliminary evidence for divergent associations of two emotion regulation strategies with cardiovascular activity and psychological stress in an AI community. Modifying health interventions to include training in effective emotion regulation may be beneficial.

Inflammation and emotion regulation: Findings from the MIDUS II study

Emotion regulation (ER) strategies are thought to contribute to mental as well as physical health outcomes. Two common ER strategies include expressive suppression, or inhibition of emotional expression, and cognitive reappraisal, which involves changing how to think about an emotion-eliciting event in order to change its emotional impact. Recent reports have hypothesized that one potential way in which ER may be linked to health outcomes is via the immune system. However, information on this putative link is scarce. The present study aims to explore whether peripheral inflammatory biomarkers are associated with individual differences in ER-strategy use. Participants (n = 117) from the Midlife in the United States II (MIDUS II) study completed the Emotion Regulation Questionnaire (ERQ), and provided a blood sample for immune biomarker extraction including interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), E-selectin, Intercellular Adhesion Molecule-1 (ICAM-1), and fibrinogen. Results showed higher levels of expressive suppression were associated with decreased IL-10, TNF-α, and ICAM-1 levels (controlling for age, sex, BMI, total prescribed medications, and depressive symptoms). Consistent with these findings, hierarchical regression results identified TNF-α as a significant predictor of expressive suppression use. In contrast, no inflammatory markers were associated with predicted use of cognitive reappraisal. Our findings suggest a link between inflammation and specific ER-strategy use. Future research should consider the effects of pro-vs. anti-inflammatory cytokines on adaptive ER and subsequent mental and physical health.

Early life stress, systemic inflammation, and neural correlates of implicit emotion regulation in adolescents

Exposure to early life stress (ELS) increases the risk for developing psychopathology; however, the mechanisms underlying this association are not clear. In this study we examined systemic inflammation as a pathway that may link exposure to stress to altered neural correlates of implicit emotion regulation in adolescents with varying levels of exposure to ELS (n = 83; 52 females, 31 males; 15.63 ± 1.10 years). We measured ventrolateral prefrontal cortex (vlPFC) activation and functional connectivity (FC) between the bilateral amygdala and the vlPFC as adolescents completed an affect labeling task in the scanner and assessed concentrations of C-reactive protein (CRP) using a dried blood spot protocol. We found that CRP levels were negatively associated with vlPFC activation during implicit regulation of negatively-valenced stimuli, and that cumulative severity of ELS exposure moderated this neuroimmune association. Severity of ELS also significantly moderated the association between CRP levels and FC between the bilateral amygdala and l-vlPFC during implicit emotion regulation: in adolescents who had been exposed to more severe ELS, higher CRP was associated with more negative frontoamygdala FC during implicit regulation of negatively-valenced stimuli. Thus, ELS may disrupt the normative association between the immune system and the neural processes that underlie socioemotional functioning potentially increasing adolescents' risk for maladaptive outcomes.

A Brief mHealth-Based Psychological Intervention in Emotion Regulation to Promote Positive Subjective Well-Being in Cardiovascular Disease Patients: A Non-Randomized Controlled Trial

The emotional impact that a cardiovascular disease may have on a person’s life can affect the prognosis and comorbidity of the disease. Therefore, emotion regulation is most important for the management of the disease. The aim of this study was to analyze the effectiveness of a brief mHealth psychological intervention in emotion regulation to promote positive subjective well-being in cardiovascular disease patients. The study sample (N = 69, 63.7 ± 11.5 years) was allocated to either the experimental group (n = 34) or control group (n = 35). The intervention consisted of a psychoeducational session in emotion regulation and an mHealth-based intervention for 2 weeks. Positive subjective well-being as a primary outcome and self-efficacy to manage the disease as a secondary outcome were assessed at five time points evaluated over a period of 6 weeks. The experimental group showed higher improvement in positive subjective well-being and self-efficacy for managing the disease compared to the control group over time. The experimental group also improved after the intervention on all outcome measures. Brief mHealth interventions in emotion regulation might be effective for improving positive subjective well-being and self-efficacy to manage the disease in cardiovascular patients.

Relationship between emotion regulation strategies and total conviction in promoting behavior change

Research conducted in the recent past have proposed total conviction as a factor associated with cognitive reappraisal that may produce changes in emotion and behavior. However, the factors that influence total conviction are not yet clearly identified. In this study, we focused on daily emotion regulation strategies and examined the relationship between emotion regulation strategies and total conviction. A total of 42 undergraduate and graduate students participated in this study. They measured their tendency toward daily emotion regulation strategies and then engaged in the cold pressor task (CPT) which is a distress tolerance task. Participants were then presented with information that encouraged them to engage in the task while enduring distress, creating a context for cognitive reappraisal of the task. Thereafter, they engaged in a second CPT. Finally, the degree of total conviction to the information that prompted reappraisal was measured. The results showed that total conviction in the experimental situation predicted behavior change. We found that the tendency to use routine cognitive reappraisal was not associated with total conviction, while the tendency to use expressive suppression would have a negative effect on total conviction. Furthermore, the expressive suppression tendency was found to moderate the relationship between total conviction and behavior change. These results indicate that the occurrence of total conviction in cognitive reappraisal leads to behavior change, though the tendency toward daily cognitive reappraisal is not related to the occurrence of total conviction in the experimental setting. The results also suggest that daily expressive suppression inhibits total conviction, particularly in situations where cognitive reappraisal is required.

The neural bases of expressive suppression: A systematic review of functional neuroimaging studies

Expressive suppression refers to the inhibition of emotion-expressive behavior (e.g., facial expressions of emotion). Although it is a commonly used emotion regulation strategy with well-documented consequences for well-being, little is known about its underlying mechanisms. In this systematic review, we for the first time synthesize functional neuroimaging studies on the neural bases of expressive suppression in non-clinical populations. The 12 studies included in this review contrasted the use of expressive suppression to simply watching emotional stimuli. Results showed that expressive suppression consistently increased activation of frontoparietal regions, especially the dorsolateral and ventrolateral prefrontal cortices and inferior parietal cortex, but decreased activation in temporo-occipital areas. Results regarding the involvement of the insula and amygdala were inconsistent with studies showing increased, decreased, or no changes in activation. These mixed findings underscore the importance of distinguishing expressive suppression from other forms of suppression and highlight the need to pay more attention to experimental design and neuroimaging data analysis procedures. We discuss these conceptual and methodological issues and provide suggestions for future research.

Multivariate Brain Activity while Viewing and Reappraising Affective Scenes Does Not Predict the Multiyear Progression of Preclinical Atherosclerosis in Otherwise Healthy Midlife Adults

Cognitive reappraisal is an emotion regulation strategy that is postulated to reduce risk for atherosclerotic cardiovascular disease (CVD), particularly the risk due to negative affect. At present, however, the brain systems and vascular pathways that may link reappraisal to CVD risk remain unclear. This study thus tested whether brain activity evoked by using reappraisal to reduce negative affect would predict the multiyear progression of a vascular marker of preclinical atherosclerosis and CVD risk: carotid artery intima-media thickness (CA-IMT). Participants were 176 otherwise healthy adults (50.6% women; aged 30-51 years) who completed a functional magnetic resonance imaging task involving the reappraisal of unpleasant scenes from the International Affective Picture System. Ultrasonography was used to compute CA-IMT at baseline and a median of 2.78 (interquartile range, 2.67 to 2.98) years later among 146 participants. As expected, reappraisal engaged brain systems implicated in emotion regulation. Reappraisal also reduced self-reported negative affect. On average, CA-IMT progressed over the follow-up period. However, multivariate and cross-validated machine-learning models demonstrated that brain activity during reappraisal failed to predict CA-IMT progression. Contrary to hypotheses, brain activity during cognitive reappraisal to reduce negative affect does not appear to forecast the progression of a vascular marker of CVD risk.

Emotion Regulation as a Pathway Connecting Early Life Adversity and Inflammation in Adulthood: a Conceptual Framework

Chronic inflammation is implicated in a variety of diseases (e.g., cardiovascular disease and cancer). Much evidence suggests that early life adversity (ELA), such as maltreatment or neglect, can increase risk for inflammation in adulthood. ELA may program proinflammatory activity via its effects on brain areas involved in emotion regulation. Of multiple emotion regulation strategies, some are considered maladaptive (e.g., expressive suppression), while others are generally adaptive (e.g., cognitive reappraisal). We propose a conceptual framework for how emotion regulation tendencies may affect vulnerability or resilience to inflammation in adults who experienced adversity in childhood and/or adolescence. In support of this framework, we summarize evidence for the relationships between emotion dysregulation and higher inflammation (i.e., vulnerability), as well as between cognitive reappraisal and lower inflammation (i.e., resilience), in healthy adults with a history of ELA. Plausible neurobiological, physiological, psychosocial, and ELA-specific factors, as well as interventions, contributing to these associations are discussed. Strengths and limitations of the extant research, in addition to ideas for future directions, are presented.

Review of Perioperative Music Medicine: Mechanisms of Pain and Stress Reduction Around Surgery

Clinical-experimental considerations and an approach to understanding the autonomic basis of improved surgical outcomes using Perioperative Music Medicine (PMM) are reviewed. Combined surgical, psycho-physiological, and experimental perspectives on Music Medicine (MM) and its relationship to autonomic nervous system (ANS) function are discussed. Considerations are given to the inter-related perioperative effects of MM on ANS, pain, and underlying vagal and other neural circuits involved in emotional regulation and dysregulation. Many surgical procedures are associated with significant pain, which is routinely treated with post-operative opioid medications, which cause detrimental side effects and delay recovery. Surgical trauma shifts the sympathetic ANS to a sustained activation impairing physiological homeostasis and causing psychological stress, as well as metabolic and immune dysfunction that contribute to postoperative mortality and morbidity. In this article, we propose a plan to operationalize the study of mechanisms mediating the effects of MM in perioperative settings of orthopedic surgery. These studies will be critical for the implementation of PMM as a routine clinical practice and to determine the potential limitations of MM in specific cohorts of patients and how to improve the treatment.

Emotions in simulation-based education: friends or foes of learning?

In simulation-based education, there is growing interest in the effects of emotions on learning from simulation sessions. The perception that emotions have an important impact on performance and learning is supported by the literature. Emotions are pervasive: at any given moment, individuals are in one emotional state or another. Emotions are also powerful: they guide ongoing cognitive processes in order to direct attention, memory and judgment towards addressing the stimulus that triggers the emotion. This occurs in a predictable way. The purpose of this paper is to present a narrative overview of the research on emotions, cognitive processes and learning, in order to inform the simulation community of the potential role of emotions during simulation-based education.

Preliminary Efficacy of an Emotion Regulation Intervention on Physical Activity and Depressive and Anxious Symptoms in Individuals in Cardiac Rehabilitation

BACKGROUND

For the 720 000 Americans expected to experience a new acute cardiac event this year, cardiac rehabilitation is an important part of recovery. Symptoms of depression and anxiety undermine recovery efforts, leaving recovering patients at risk for diminished functional capacity and heightened risk of mortality. Poor emotion regulation can worsen symptoms of depression and anxiety and hinder recovery efforts.

OBJECTIVE

The purpose of this randomized controlled trial was to evaluate the early efficacy testing of a theoretically based emotion regulation treatment (Regulating Emotions to Improve Self-management of Nutrition, Exercise, and Stress [RENEwS]) designed to assist survivors of an acute cardiac event in cardiac rehabilitation to optimize recovery.

METHODS

Survivors of an acute cardiac event in cardiac rehabilitation (n = 30, 83% men) were randomized to five 1-hour in-person group sessions of RENEwS or a phone-based attention-control group. Participants completed measures of depression and anxiety symptoms at 3 time points. Moderate to vigorous physical activity (MVPA) was objectively measured for 7 days at each time point using waist-worn actigraphy monitors. Between-group differences were calculated using analysis of variance with Cohen f effect sizes calculated to evaluate initial efficacy.

RESULTS

There was no statistically significant difference in depression, anxiety, or MVPA over time based on group assignment (all P > .05). Compared with attention control participants, in RENEwS participants, preliminary effects showed greater reductions in depression (Cohen f = 0.34) and anxiety (Cohen f = 0.40) symptoms but only modest improvements in MVPA from baseline to 5 months (Cohen f = 0.08).

CONCLUSIONS

Findings show that RENEwS is a promising emotion regulation intervention to enhance cardiac rehabilitation and potentially decrease symptoms of depression and anxiety.

A review and novel theoretical model of how negative emotions influence inflammation: The critical role of emotion regulation

Psychological distress is an inevitable part of life. Research drawing on theories from clinical psychology, health psychology, and psychoneuroimmunology (PNI) has identified relationships between negative emotions such as anxiety and sadness with inflammation. When not regulated properly, negative emotions can create biological wear and tear on the body that can increase risk for morbidity and mortality. This review discusses previously available research on relationships between negative emotions and emotion regulation with inflammation among both physically healthy adults and those with chronic illnesses. I then present a novel comprehensive biobehavioral model of negative emotionality. This model emphasizes the influence of negative emotions and their contribution to heightened inflammation. Further, I also discuss how emotion regulation (including perseverative processes such as worry and rumination) mediates this association. The relationships between negative emotionality and emotion regulation may be bidirectional, and empirical investigation of this model should specifically seek to disentangle these relationships. The proposed model offers the opportunity to advance PNI research through understanding how emotional factors alter inflammation and contribute to accelerated biological aging and disease risk.

Psychological and biological resilience modulates the effects of stress on epigenetic aging

Our society is experiencing more stress than ever before, leading to both negative psychiatric and physical outcomes. Chronic stress is linked to negative long-term health consequences, raising the possibility that stress is related to accelerated aging. In this study, we examine whether resilience factors affect stress-associated biological age acceleration. Recently developed "epigenetic clocks" such as GrimAge have shown utility in predicting biological age and mortality. Here, we assessed the impact of cumulative stress, stress physiology, and resilience on accelerated aging in a community sample (N = 444). Cumulative stress was associated with accelerated GrimAge (P = 0.0388) and stress-related physiologic measures of adrenal sensitivity (Cortisol/ACTH ratio) and insulin resistance (HOMA). After controlling for demographic and behavioral factors, HOMA correlated with accelerated GrimAge (P = 0.0186). Remarkably, psychological resilience factors of emotion regulation and self-control moderated these relationships. Emotion regulation moderated the association between stress and aging (P = 8.82e-4) such that with worse emotion regulation, there was greater stress-related age acceleration, while stronger emotion regulation prevented any significant effect of stress on GrimAge. Self-control moderated the relationship between stress and insulin resistance (P = 0.00732), with high self-control blunting this relationship. In the final model, in those with poor emotion regulation, cumulative stress continued to predict additional GrimAge Acceleration even while accounting for demographic, physiologic, and behavioral covariates. These results demonstrate that cumulative stress is associated with epigenetic aging in a healthy population, and these associations are modified by biobehavioral resilience factors.

Mindfulness interventions for offsetting health risk following early life stress: Promising directions

Early life stress (ELS), common to childhood maltreatment, socioeconomic disadvantage, and racial discrimination, is thought to create a proinflammatory phenotype that increases risk for poor health in adulthood. Systemic change is needed to address the root causes of ELS, but a substantial number of adults are already at increased health risk by virtue of ELS exposure. Interventions that target stress pathways have the potential to interrupt the trajectory from ELS to inflammatory disease risk in adulthood. Mindfulness-based interventions (MBIs), which train acceptance toward present-moment experience, have shown promise for reducing stress and improving a variety of stress-sensitive health outcomes. Although MBIs have primarily been conducted in more advantaged populations, evidence suggests that they may be uniquely effective for improving mental health and health-related quality of life among those with a history of ELS. Whether these effects extend to physical health remains unknown. To shed light on this question, I review evidence that MBIs influence inflammatory markers in at-risk samples, explore the promise of MBIs for improving stress-related health outcomes in diverse at-risk populations, and describe adaptations to MBIs that may increase their acceptability and efficacy in populations exposed to ELS. This prior work sets the stage for well-controlled RCTs to evaluate whether MBIs influence stress and inflammatory pathways among those exposed to ELS and for pragmatic and implementation trials focused on disseminating MBIs to reach these at-risk populations. Overall, the evidence assembled here shows the potential of MBIs for offsetting physical health risk related to ELS.

A Biopsychosocial Approach to Grief, Depression, and the Role of Emotional Regulation

According to the field of affective neuroscience, grief has been identified as one of the seven primary emotions necessary for human survival. However, maladaptive grief could cause significant impairment in an individual's life, leading to psychopathologies such as major depressive disorder. Research on grief has shifted to a biopsychosocial approach, leaving behind outdated models-such as the Kübler-Ross theory-that have shown poor consistency. The field of psychoneuroimmunology has identified adverse life events such as social loss as being associated with major depressive disorder, and inflammatory processes in chronic health conditions. Likewise, scientists in the field of affective neuroscience have theorized that prolonged and sustained activation of the grief neurological pathway can cause a cascade of neurotransmitters that inhibits the reward-seeking system, causing symptoms of depression. The objective of this review is to highlight findings on the grief process using a biopsychosocial approach to explore grief's impact on psychopathophysiology.

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world. PROTOCOL REGISTRATION: The stage 1 protocol for this Registered Report was accepted in principle on 12 May 2020. The protocol, as accepted by the journal, can be found at https://doi.org/10.6084/m9.figshare.c.4878591.v1.

Systemic inflammation is associated with differential neural reactivity and connectivity to affective images

Systemic inflammation is increasingly appreciated as a predictor of health and well-being. Further, inflammation has been shown to influence and be influenced by affective experiences. Although prior work has substantiated associations between inflammatory and affective processes, fewer studies have investigated the neurobiological correlates that underlie links between systemic, low-grade inflammation and affective reactivity. Thus, the current study examined whether markers of systemic inflammation (i.e. interleukin-6, C-reactive protein) are associated with differential patterns of neural activation and connectivity in corticolimbic regions in response to affective images. We investigated this question in a sample of 66 adults (44 women, M age = 54.98 years, range = 35–76) from the Midlife in the United States study. Higher levels of inflammation were associated with lower activity in limbic regions (i.e. amygdala, hippocampus, anterior insula, temporal pole) when viewing positive (vs neutral) images. Higher levels of inflammation were also associated with greater connectivity between the hippocampus and the medial prefrontal cortex in response to positive images. Inflammatory markers were not associated with significant differences in activation or connectivity to negative images. These findings highlight the utility of health neuroscience approaches in demonstrating that physiological processes such as inflammation are related to how our brains respond to affective information.

Emotional Vulnerability to Short Sleep Predicts Increases in Chronic Health Conditions Across 8 Years

BACKGROUND

Sleep is a robust determinant of next-day emotions, but people vary in the extent that their emotions fluctuate on days following short sleep duration. These individual differences in day-to-day sleep and emotion dynamics may have long-term health implications.

PURPOSE

To evaluate emotional vulnerability to short sleep (within-person associations between sleep duration and next-day emotions) as a risk factor for future chronic conditions.

METHODS

Adults aged 33-84 (N = 1,426; 57% female) in the Midlife in the United States Study reported sleep duration and emotions by telephone for eight consecutive days. Chronic conditions were assessed via checklist at baseline and at a median follow-up of eight years (range: 5-10 years). Short sleep was examined in three ways: person-centered continuous variable, ≤6 hr, and <7 hr; long sleep was defined as ≥9 hr.

RESULTS

Multilevel structural equation models revealed that people with greater negative emotions following nights of sleep ≤6 hr (vs. their negative emotions after longer sleep) had increased chronic conditions at follow-up, compared to people who were less emotionally vulnerable to short sleep (Est. = 1.04, SE = .51, p < .028). Smaller declines in positive emotions following ≤6 hr of sleep were marginally predictive of lower risk for chronic conditions (Est. = -.77, SE = .44, p = .054). Emotional vulnerability to <7, ≥9, and continuous sleep hours were not associated with subsequent chronic conditions.

CONCLUSIONS

Emotional vulnerability to short sleep is a unique risk factor for the development of chronic conditions, independent of mean-level sleep duration and emotions.

Authentic leadership and employee health: a conditional process model

Purpose

The purpose of this paper is to examine the effect of authentic leadership (AL) on employees' health via employees' perception of climate of authenticity (PCA) across two studies. In study 2, the authors additionally explore the moderating role of employees' neuroticism.

Design/methodology/approach

The hypotheses were tested across two studies using two-wave survey data. In study 1 (n = 104), the mediation hypothesis was tested. Study 2 (n = 146) extended study 1 and examined the moderated mediation model.

Findings

Across both studies, AL is positively related to employee health, and employees' perceived climate of authenticity mediates this relationship. Study 2 additionally shows that employees' neuroticism moderates this indirect effect such that perceived climate of authenticity instigated by AL is particularly conducive for employees high in neuroticism as opposed to those low in neuroticism.

Practical implications

Findings emphasize the health-promoting effect of AL. It is recommended that organizations cascade, through their leaders, emotional display rules that encourage genuine emotional expression.

Originality/value

This paper addresses gaps in the leadership literature through investigating perceived climate of authenticity, a mediating variable that lies at the heart of AL, and integrating the role of employees' personality in the leadership process.

Suppression, but not reappraisal, is associated with inflammation in trauma-exposed veterans

BACKGROUND

Emotion dysregulation can elicit inflammatory activity. The current study examined whether specific maladaptive and adaptive emotion regulation strategies were associated with inflammatory markers in trauma-exposed veterans, above and beyond PTSD.

METHODS

In a cohort study, 606 participants exposed to a Criterion A trauma and recruited from Veteran Health Administration facilities completed fasting blood draws, the Emotion Regulation Questionnaire, and the Clinician Administered PTSD Scale-IV. Inflammation was assessed with high sensitivity C-reactive protein (hsCRP), white blood cell count (WBC), and fibrinogen levels. An inflammation index was created by summing standardized log-transformed levels of the three biomarkers. Our primary linear regression models were adjusted for sex, age, race, education, income, creatinine, and PTSD.

RESULTS

Suppression, but not cognitive reappraisal, was significantly associated with higher levels of the inflammatory index (β = 0.14, p = 0.001). Parallel analyses for the individual inflammatory markers also showed suppression, but not reappraisal, was significantly associated with higher hsCRP (β = 0.11, p = 0.01), WBC (β = 0.11, p = 0.01), and fibrinogen (β = 0.10, p = 0.02).

CONCLUSIONS

Emotional suppression is related to elevated systemic inflammation independent of PTSD. Cognitive reappraisal is unrelated to inflammation. Findings suggest over-utilization of maladaptive, rather than under-utilization of adaptive, emotion regulation strategies may be associated with systemic inflammation in trauma-exposed veterans.
