How positive emotions build physical health: perceived positive social connections account for the upward spiral between positive emotions and vagal tone

Investigating the relationship between goal orientation, self-efficacy, positive emotionality, and affective engagement among Chinese students

This study delved into the complex interplay between self-efficacy, achievement goals, positive emotions, and affective engagement among university students in China. To achieve this, a stratified random sampling technique was employed, resulting in a sample of 391 students from four geographically distinct universities across China. The data collection relied on self-reported questionnaires that measured academic self-efficacy, goal orientation (specifically focusing on mastery versus performance goals), positive emotions, and various aspects of affective engagement, including enjoyment, satisfaction, and interest in learning. Structural equation modeling (SEM) served as the primary statistical tool to analyze the hypothesized relationships between these variables. The analysis revealed a network of positive associations, indicating that students with higher levels of self-efficacy and positive emotionality reported experiencing greater affective engagement in their academic pursuits. Furthermore, a stronger mastery goal orientation was associated with increased enjoyment, satisfaction, and interest in learning. Self-efficacy and positive emotionality also indirectly influenced affective engagement through goal orientation, suggesting that students with higher self-belief and positive emotions were more likely to adopt mastery goals, leading to more positive learning experiences. This study highlights the importance of self-efficacy, positive emotionality, and goal orientation in shaping students' affective engagement. By fostering these factors, educators can create more positive and engaging learning environments for university students.

Attenuation processes in positive social emotion upregulation: Disentangling functional role of ventrolateral prefrontal cortex

Positive emotions determine individual well-being and sustainable social relationships. Here, we examined the neural processes mediating upregulation of positive social emotions using functional magnetic resonance imaging in healthy female volunteers. We identified brain regions engaged in upregulation of positive social emotions and applied a parametric empirical Bayes approach to isolate modulated network connectivity patterns and assess how these effects relate to individual measures of social perception. Our findings indicate that upregulation of positive social emotions shapes the functional interplay between affective valuation and cognitive control functions. We revealed a selective increase of bilateral posterior ventrolateral prefrontal cortex (vlPFC) activity and attenuation of activity in right anterior vlPFC under control influences from more superior prefrontal regions. We also found that individual perception of sociality modulates connectivity between affective and social networks. This study expands our understanding of neural circuits required to balance positive emotions in social situations and their rehabilitative potential.

Does Participation in Group Music Activities and Pro-Social Behavior Among College Students Have an Association? A Study of the Interlocking Mediating Effects of Positive Social Connections and Peer Support

It has been demonstrated that music can be an effective tool for shaping the future of college students. This study aimed to investigate the effects of college students' participation in group music activities on their pro-social behavior, and for the first time introduced the psychological variables of "positive social connections" and "perceived peer support". The results of this study show the following: (1) Group music activity participation is positively associated with pro-social behavior. (2) Positive social connections serve as a mediator between college student group music activity participation and college students' pro-social behavior. (3) Perceived peer support serves as a mediator between college student group music activity participation and college students' pro-social behavior. (4) Positive social connections and perceived peer support interlock to shape the relationship between group music activity participation and pro-social behavior. This study explores the intrinsic factors of college students' participation in group music activities to promote their pro-social behavior from the dual perspectives of music psychology and behavioral psychology, provides empirical support for educational practice, emphasizes the importance of group music activities in promoting the development of college students' pro-social behavior, and provides insights into new perspectives for college students' overall healthy development.

Psychometric properties of the Partner Ambivalence Scale in middle-aged and older adults

OBJECTIVES

Ambivalent feelings in a partner relationship, characterized by simultaneous positive and negative emotional experiences, can significantly influence individuals' mental health. Traditionally measured indirectly, this study introduces the Partner Ambivalence Scale (PAS), developed for directly capturing the complexity of ambivalent emotions. This study aimed to analyze the psychometric properties of the PAS, and assess the effects of ambivalent feelings on partner relationship quality and depressive symptomatology.

METHOD

390 individuals (60% women), 40 years or older (M = 60.88, SD = 10.7), and in a partner relationship, participated. Data collected included ambivalent feelings in couples, marital satisfaction, frequency of arguments, and depressive symptoms.

RESULTS

The exploratory factor analysis of the PAS yielded a one factor structure explaining 59% of the variance of ambivalent feelings. Higher ambivalent feelings were associated with lower marital satisfaction, higher frequency of disagreements, and higher depressive symptoms. Even when controlling for covariates, ambivalent feelings contributed significantly to the explanation of depress on.

CONCLUSION

The PAS demonstrates good psychometric properties, making it suitable for use with middle-aged and older adults. Ambivalent feelings toward the partner are significant for understanding partner relationship quality and mental health and may increase vulnerability to depressive symptoms during middle and older age.

Bidirectional Relations Among Maternal Positive Emotion, Infant Positive Emotionality, and Infant Physiological Regulation Across the First 18 Months of Life

Respiratory sinus arrhythmia (RSA), a marker of self-regulation, has been linked to developmental outcomes in young children. Although positive emotions may have the potential to facilitate physiological self-regulation, and enhanced self-regulation could underlie the development of positive emotions in early childhood, the relation between positive emotions and physiological self-regulation in infancy has been relatively overlooked. The current study examined the bidirectional associations among maternal positive emotion, infant positive emotionality, and infant resting RSA across the first 18 months of life. We used data from the Longitudinal Attention and Temperament Study (LanTs; N = 309 in the current analysis) to test the within- and between-person relations of study variables over time using a random-intercepts cross-lagged panel model. We found that infants with higher overall levels of positive emotionality also displayed greater resting RSA, and their mothers exhibited higher levels of positive emotion. However, there were negative cross-lagged associations within-person; higher than average infant positive emotionality predicted lower levels of infant resting RSA at the subsequent timepoint during early infancy, whereas higher than average infant RSA subsequently predicted decreased levels of infant positive emotionality later in infancy. Results highlight the importance of considering transactional relations between positive emotion and physiological self-regulation in infancy.

A triple trust penalty? The majority-minority gap in subjective wellbeing

This study introduces a social capital perspective to the majority-minority gap in wellbeing. We explore the role of social trust and test specifically whether racial and ethnic minorities may experience a triple trust penalty. First is a level penalty, where minorities exhibit lower levels of trust, potentially adversely affecting their wellbeing. Second, there may be a return penalty, where minorities may experience a diminished return from being trustful. Third, there may be a protection penalty, where minorities experience reduced benefits from residing in a high-trust context. Our empirical analyses are based on data from multiple waves of the European Social Survey (Round 4-10, 2008-2020) with over 300,000 individuals from 38 European countries. Our analyses indicate support for the level penalty, but we found no evidence for the return or protection penalties. Specifically, we show that racial and ethnic minorities' lower levels of trust can have harmful impacts on their happiness and life satisfaction. However, an increase in trust yields greater wellbeing among racial and ethnic minorities, and residing in a high-trust context also appears to have a more substantial impact on the well-being of racial and ethnic minorities as compared to their counterparts. The results suggest that promoting trust can effectively narrow the wellbeing gap among various racial groups.

Coping With Uncertainty: Use of Contemplative Practices Amid the COVID-19 Pandemic in the United States

Scant research has attempted to understand the use and frequency of contemplative practices across social groups of older adults in the context of uniquely uncertain and stressful circumstances, such as the COVID-19 pandemic. Using data from a nationwide web-based survey (n = 1861), we examined the change in the frequency of contemplative practices and variation across sociodemographic, health, and psychological status and we documented a significant increase in the use of prayer and meditation since the beginning of the pandemic. Minority groups and those with lower income reported praying longer than their counterparts. Respondents who were unmarried, women, and more educated were more likely to meditate, whereas lower-educated respondents were more likely to pray during the pandemic. Greater use of these practices was found among participants with higher anxiety. Our study offers much-needed guidance for future intervention studies to improve psychological well-being among diverse groups of older adults facing stressful circumstances.

Positive psychological well-being and cardiovascular health

Positive psychological well-being (PPWB) is increasingly recognized as a critical factor in cardiovascular health of both healthy individuals and those with cardiovascular diseases (CVD). This mini-review synthesizes the current state of knowledge on the relationship between PPWB and cardiovascular health, examining relevant studies on PPWB in both populations. The conceptualization of PPWB encompasses hedonic and eudaimonic facets, with constructs such as optimism, purpose in life, and vitality playing crucial roles. Studies among healthy individuals show a significant association between PPWB and improved cardiovascular health indicators, while research among cardiac patients highlights the importance of PPWB in predicting outcomes such as mortality and rehospitalization. Mechanistic pathways linking PPWB and cardiovascular health include biological processes, health behavior changes, and additional psychological resources that mitigate stress. Despite the growing evidence, questions remain unanswered, necessitating further research to understand these relationships and develop effective interventions. Promoting psychological well-being alongside physical health can enhance cardiovascular disease prevention and management, offering a comprehensive approach to improving patient outcomes and overall well-being.

The foundations of mind-body medicine: Love, good relationships, and happiness modulate stress and promote health

Although stress is an everyday fact of life, it can lead to poor health outcomes, particularly when intense or prolonged. However, humans have unique cognitive abilities and thus may be able to combat stress by engaging critical psychological defence mechanisms. In this review, we discuss the field of mind-body medicine, which focuses on improving our understanding of the mechanisms underlying this response and developing interventions that might be used to limit the effects of chronic stress. We review the findings of past and current research in this field that has focused on the impact of psychological, emotional, and behavioural factors, including love, social connectedness, and happiness on human health and the amelioration of pain as well as other signs and symptoms of disease. While these studies have not yet led to confirmed, quantifiable conclusions, the overall weight of evidence suggests that happiness (defined as a personal sense of well-being) may be directly associated with improved health parameters and reductions in debilitating symptoms. Collectively, these findings suggest that interventions designed to promote stress mitigation, notably those that encourage social activity, may lead to significant improvements in human health.

Compassionate mind training for people with Parkinson's disease: A pilot study and predictors of response

INTRODUCTION

People with Parkinson's disease (PD) often present with disabling neuropsychiatric symptoms. Compassionate mind training (CMT) is a psychological approach effective in reducing stress and promoting psychological well-being. Heart rate variability (HRV), a measure reflecting sympathovagal balance, has been associated with psychological well-being and a compassionate attitude.

AIM

To assess the feasibility and effectiveness of CMT in enhancing the quality of life and psychological well-being in PD patients. Additionally, we evaluated HRV as a physiomarker for assessing the CMT outcomes.

METHODS

Twenty-four PD patients participated in the study. A 6-week online CMT intervention was delivered on a weekly basis. At baseline and post-intervention patients completed questionnaires assessing depression, anxiety and quality of life. In a subsample of 11 patients, HRV was measured at baseline and post-intervention in three conditions: at rest, during stress and after 3 min of deep breathing.

RESULTS

The attendance rate was 94.3%. Quality of life and perceived stigma improved post-intervention as compared with baseline (p = 0.02 and p = 0.03 for PD Questionnaire-39 total score and Stigma subscore, respectively). After CMT, patients presented better physiological regulation to stress, as measured by higher HRV as compared with baseline (p = 0.005). Notably, patients who were more resilient to stress at baseline (less decrease in HRV during stress) experienced a more substantial reduction in anxiety and depression following CMT.

CONCLUSIONS

CMT is feasible and can improve quality of life and stigma in PD patients. HRV emerges as a promising physiomarker for predicting and measuring the outcomes of psychological interventions in PD.

Engagement with nature and proinflammatory biology

BACKGROUND

Prior evidence indicates that contact with nature improves physical health, but data explicitly linking engagement with nature to biological processes are limited.

DESIGN

Leveraging survey and biomarker data from 1,244 adults (mean age = 54.50 years, range = 34-84 years) from the Midlife in the United States (MIDUS II) study, we examined associations between nature engagement, operationalized as the frequency of pleasant nature encounters, and systemic inflammation. Concentrations of interleukin-6 (IL-6), C-reactive protein (CRP), and fibrinogen were measured from fasting blood samples. Analyses adjusted for sociodemographic, health behavior, and psychological well-being covariates.

RESULTS

More frequent positive nature contact was independently associated with lower circulating levels of inflammation.

CONCLUSIONS

These findings add to a growing literature on the salubrious health effects of nature by demonstrating how such experiences are instantiated in downstream physiological systems, potentially informing future interventions and public health policies.

Choosing Health: acceptability and feasibility of a theory-based, online-delivered, tailored weight loss, and weight loss maintenance intervention

Few weight loss and weight loss maintenance interventions are tailored to include factors demonstrated to predict the user's behavior. Establishing the feasibility and acceptability of such interventions is crucial. The aim of this study was to assess the acceptability and feasibility of a theory-based, tailored, online-delivered weight loss and weight loss maintenance intervention (Choosing Health). We conducted a mixed methods process evaluation of the Choosing Health tailored intervention, nested in a randomized controlled trial (N = 288) with an embedded N-of-1 study, investigating participants' and implementers' experiences related to intervention context, implementation, and mechanisms of impact. Measures included: (i) surveys, (ii) data-prompted interviews (DPIs) with study participants, (iii) semi-structured interviews with implementers, and (iv) intervention access and engagement data. Five themes described the acceptability of the intervention to participants: (i) monitoring behavior change and personal progress to better understand the weight management process, (ii) working collaboratively with the intervention implementers to achieve participants' goals, (iii) perceived benefits of non-judgmental and problem-solving tone of the intervention, (iv) changes in personal perception of the weight management process due to intervention tailoring, and (v) insufficient intervention content tailoring. The intervention delivery was feasible, however, emails and text messages differed in terms of accessibility and resources required to deliver the content. The use of Ecological Momentary Assessment as a technique to gather personal data for further tailoring was acceptable, and facilitated behavior change monitoring. Personalization of the intervention content above and beyond domain-specific issues, for example, by addressing participants' social roles may better match their needs. Support from the implementers and feedback on body composition changes may increase participants' engagement.

Facilitating the coping and development of college students with mental disorders: a positive clinical psychology approach

In serving college students with mental disorders, on-campus mental health professionals have been lacking integrative theoretical frameworks to guide their missions of prevention, remedy, and development facilitation. In the current paper, we propose the positive clinical psychology as a theoretically and practically valuable framework for these missions by narratively reviewing the preventive, remedial, and developmental mechanisms derived from the theory and summarizing the most recent empirical evidence that supports each mechanism. We further discuss why and how these mechanisms and findings can be applied to on-campus mental health services to facilitate the resilience and optimal development of college students with mental disorders. Particularly, the use of resilience-focused and strength-based intervention strategies are promoted for services.

Culture and Awe: Understanding Awe as a Mixed Emotion

Recent work is establishing awe as an important positive emotion that offers physical and psychological benefits. However, early theorizing suggests that awe's experience is often tinged with fear. How then, do we reconcile emergent positive conceptualizations of awe with its more fearful elements? We suggest that positive conceptualizations of awe may partially reflect modern Western experiences of this emotion, which make up the majority of participant samples when studying awe. To test whether awe contains more fearful qualities outside of Western cultures, we compared participants' experiences of this emotion in China to those in the United States. In a two-week daily diary study (Study 1), Chinese participants reported greater fear than American participants during experiences of awe, but not a comparison positive emotion. In response to a standardized awe induction (Study 2), Chinese participants reported more fear, whereas American participants reported more positive emotions. Physiological changes in autonomic activity differed by culture only for heart rate, but not skin conductance or respiratory sinus arrhythmia. These findings reveal that awe may be experienced as a more fearful, mixed emotion in China than in the United States and suggest that current positive conceptualizations of awe may reflect a disproportionate reliance on modern Western samples.

When the body fosters empathy: The interconnectivity between bodily reactivity, meditation, and embodied abstract concepts

Empathy is a fundamental social ability that allows humans to infer others' emotions and intentions. Empathy is thought to be rooted in bodily sensations coming from the autonomic nervous system. In parallel, the functionality and perceptions coming from the autonomic nervous system could be improved by practicing activities that involve mind-body interactions, such as meditation. Furthermore, perceptions from the autonomic nervous system are thought to be important in the embodiment of abstract concepts. Consequently, in the current study, we collected data online from 581 participants and explored the associations between levels of empathy and (1) the practice of meditation, music, and sports; (2) the impact of self-report measures on bodily awareness and reactivity; and (3) the embodiment of abstract concepts in interoception. In line with previous studies, Meditators were found to have higher empathy scores than Non-Meditators. In addition, lower levels of autonomic reactivity in organs above the diaphragm were associated with higher empathy. Finally, we also observed that empathy was positively associated with interoceptive components of abstract concepts in those participants with high autonomic reactivity. Taken together, the results suggest that meditation practice and having low autonomic reactivity are associated with empathy, arguably through the downregulation of autonomic responses. Implications for mind-body interaction in meditation and its role in promoting empathy are discussed.

Exploring the Longitudinal Influence of Perceived Social Support, HIV Stigma, and Future Orientation on Depressive Symptoms Among People Living with HIV in China

Prior studies demonstrated that perceived social support is negatively associated with behavioral and mental health problems among people living with HIV (PLWH). However, longitudinal data regarding the associations between perceived social support, internalized HIV stigma, future orientation, and depressive symptoms are limited. The current study aimed to investigate the possible indirect relationship between these variables using four-wave follow-up data (6-month intervals) from a sample of 1,098 Chinese PLWH (Mage = 38.63, SD = 9.20, age range: 18-60 years; 63.9% men). All participants were asked to complete an adapted version of Perceived Social Support Scale, Internalized HIV Stigma Scale, Optimism About the Future Scale, and Center of Epidemiological Studies Depression Scale. Results indicated that perceived social support at baseline was negatively related to depressive symptoms at wave 4. Internalized HIV stigma at wave 2 and future orientation at wave 3 indirectly affected the linkage between perceived social support at baseline and depressive symptoms serially over time. This study highlights the essential role of perceived social support in alleviating depressive symptoms among PLWH, and underscores the complex interplay in which internalized HIV stigma and future orientation serially mediated the relationship between perceived social support and depressive symptoms. These findings suggest the need for integrated interventions to enhance social support, address HIV-related stigma, and promote positive future orientation, which could potentially alleviate depressive symptoms and promote mental well-being among PLWH.

Enhancing emotion regulation: investigating the efficacy of transcutaneous electrical acupoint stimulation at PC6 in reducing fear of heights

This study investigated the impact of transcutaneous electrical acupoint stimulation (TEAS) at Neiguan acupoint (PC6) on the physiological and behavioral responses of participants exposed in virtual height. 40 participants were included in the study and were randomly assigned to either a control group or an intervention group. Participants had an immersive experience with a VR interactive platform that provided somatosensory interaction in height stimulation scenes. Psychological scores, behavioral and cognitive performance, and physiological responses were recorded and analyzed. The results indicated that the intervention group had significantly lower fear scores compared to the control group. Analysis of heart rate variability revealed that the intervention group exhibited improved heart rate variability, indicating enhanced cardiovascular function and emotion regulation. The behavioral and cognitive results demonstrated that the intervention group exhibited higher left eye openness, faster reaction times, and greater movement distance, suggesting enhanced attentional focus, cognitive processing, and reduced avoidance behaviors. These findings suggest that TEAS at PC6 can effectively reduce fear and improve the regulation of physiological and behavioral responses to negative emotional stimuli.

Mixed-methods feasibility outcomes for a novel ACT-based video game 'ACTing Minds' to support mental health

OBJECTIVES

To determine the feasibility and acceptability of 'ACTing Minds', a novel single-player adventure video game based on acceptance and commitment therapy (ACT).

DESIGN

A single-arm, mixed-methods repeated measures feasibility study.

SETTING

Intervention and questionnaires were completed at home by participants. Semistructured interviews were also conducted at home via the Zoom platform.

PARTICIPANTS

Thirty-six participants were recruited into the study, 29 completed all phases of the feasibility design. Eligibility criteria required participants to be over the age of 18 and self-reporting experiencing ongoing depression, anxiety or stress.

INTERVENTION

Participants completed a single session of the 'ACTing Minds' video game, lasting approximately 1 hour, designed to educate users on key principles from ACT.

PRIMARY OUTCOME MEASURES

Participant recruitment and retention, questionnaire completion, long-term intervention adherence and acceptability of the intervention. Reflexive thematic analysis was conducted on semistructured interviews run immediately postintervention and 3 weeks later.

SECONDARY OUTCOME MEASURES

Measures of depression, anxiety, stress, psychological flexibility, social connectedness and well-being were assessed at baseline, immediately following intervention completion, and after a 3-week follow-up period. We used a standardised battery of questionnaires.

PRIMARY RESULTS

Twenty-nine participants completed the study. A reflexive thematic analysis indicated that participants responded positively to the intervention and the study at all stages. Themes reflect participants' desire for an engaging therapeutic experience, use of game for exploring emotions, as well as their perspectives on how they had applied their learning to the real world.

SECONDARY RESULTS

Quantitative results indicated small to large effect sizes associated with decreases in depression (ηp2 = 0.011), anxiety (ηp2 = 0.096) and stress (ηp2 = 0.108), and increases in psychological flexibility (ηp2 = 0.060), social connectedness (ηp2 = 0.021), well-being (ηp2 = 0.011) and participation in usual activities (ηp2 = .307).

CONCLUSIONS

Implementation of the 'ACTing Minds' intervention is warranted, based on both qualitative and quantitative outcomes.

If it Ain't Broke, Don't Fix it: Positive Versus Negative Emotion Regulation in Daily Life and Depressive Symptoms

BACKGROUND

Despite the importance of positive emotions for affective psychopathology, prior research primarily focused on negative emotion regulation. To address this gap, this ecological momentary assessment study compared a broad set of emotion regulation strategies in the context of positive versus negative emotions regarding their effectiveness and associations with depressive symptoms.

METHODS

We analyzed data from 1066 participants who were notified five times daily for seven consecutive days to complete a smartphone survey assessing their predominant emotions, strategies to regulate them, and subsequent emotional outcomes.

RESULTS

Findings show that the effectiveness of most regulation strategies depended on whether the emotional context was positive or negative. While acceptance and savoring predicted improved emotional outcomes across emotional contexts, reappraisal and problem-solving were associated with deteriorated emotional outcomes and increased depressive symptoms when regulating positive but not negative emotions.

LIMITATIONS

Future studies should replicate our findings in demographically and culturally diverse clinical samples to improve generalizability.

CONCLUSION

These results emphasize that strategies effective for regulating negative emotions may be less helpful in the context of positive emotions. Thus, context-specific interventions may be a promising approach to improve the treatment of affective disorders.

Meditation, Compassionate Love, and Mental Health in Later Life

PURPOSE

Understanding of the mechanisms by which meditation imparts beneficial effects on later-life mental health is limited. The current study assessed the role of compassionate love in mediating the relationship between meditation and mental health in later life.

METHOD

Using data from a nationwide web-based survey (N = 1,861), we examined the indirect effects of meditation on depressive symptoms and anxiety via compassionate love.

RESULTS

Participants who practiced meditation (compared to those who did not) had significantly higher feelings of being loved (b = 0.11, p < 0.05); those who experienced more love had lower depressive symptoms (b = -2.10, p < 0.001) and anxiety (b = -0.99, p < 0.001). Meditation also had significant indirect effects (via compassionate love) on depressive symptoms (b = -0.23, p < 0.05) and anxiety (b = -0.11, p < 0.05).

CONCLUSION

This study underscores the need for contemplative interventions that foster compassionate love to improve mental health in later life. [Journal of Gerontological Nursing, 50(3), 40-50.].

Validity of resting heart rate derived from contact-based smartphone photoplethysmography compared with electrocardiography: a scoping review and checklist for optimal acquisition and reporting

Background

With the rise of smartphone ownership and increasing evidence to support the suitability of smartphone usage in healthcare, the light source and smartphone camera could be utilized to perform photoplethysmography (PPG) for the assessment of vital signs, such as heart rate (HR). However, until rigorous validity assessment has been conducted, PPG will have limited use in clinical settings.

Objective

We aimed to conduct a scoping review assessing the validity of resting heart rate (RHR) acquisition from PPG utilizing contact-based smartphone devices. Our four specific objectives of this scoping review were to (1) conduct a systematic search of the published literature concerning contact-based smartphone device-derived PPG, (2) map study characteristics and methodologies, (3) identify if methodological and technological advancements have been made, and (4) provide recommendations for the advancement of the investigative area.

Methods

ScienceDirect, PubMed and SPORTDiscus were searched for relevant studies between January 1st, 2007, and November 6th, 2022. Filters were applied to ensure only literature written in English were included. Reference lists of included studies were manually searched for additional eligible studies.

Results

In total 10 articles were included. Articles varied in terms of methodology including study characteristics, index measurement characteristics, criterion measurement characteristics, and experimental procedure. Additionally, there were variations in reporting details including primary outcome measure and measure of validity. However, all studies reached the same conclusion, with agreement ranging between good to very strong and correlations ranging from r = .98 to 1.

Conclusions

Smartphone applications measuring RHR derived from contact-based smartphone PPG appear to agree with gold standard electrocardiography (ECG) in healthy subjects. However, agreement was established under highly controlled conditions. Future research could investigate their validity and consider effective approaches that transfer these methods from laboratory conditions into the "real-world", in both healthy and clinical populations.

Physiological evidence of stress reduction during a summer Antarctic expedition with a significant influence of previous experience and vigor

Antarctica provides a unique environment for studying human adaptability, characterized by controlled conditions, limited sensory stimulation, and significant challenges in logistics and communication. This longitudinal study investigates the relationship between stress indicators, with a specific focus on mean sleep heart rate, during a COVID-19 quarantine and subsequent 83 days long summer Antarctic expedition at the J. G. Mendel Czech Antarctic Station. Our novel approach includes daily recordings of sleep heart rate and weekly assessments of emotions, stress, and sleep quality. Associations between variables were analyzed using the generalized least squares method, providing unique insights into nuances of adaptation. The results support previous findings by providing empirical evidence on the stress reducing effect of Antarctic summer expedition and highlight the importance of previous experience and positive emotions, with the novel contribution of utilizing physiological data in addition to psychological measures. High-frequency sampling and combination of psychological and physiological data addresses a crucial gap in the research of stress. This study contributes valuable knowledge to the field of psychophysiology and has implications for expedition planners, research organizations, teams in action settings, pandemic prevention protocols, global crises, and long-duration spaceflight missions. Comprehensive insights promote the well-being and success of individuals in extreme conditions.

Loving-kindness and compassion meditations in the workplace: A meta-analysis and future prospects

Loving-kindness and compassion meditation (LKCM) have been well applied among employees to improve their health and well-being. Existing studies on LKCM have also provided supportive evidence of its benefits and effectiveness under organizational contexts. The current meta-analytical study aimed to systematically summarise the effects of LKCM in the workplace and to outline directions for future research and practice. Among 327 empirical studies on LKCM published until March 2022, 21 trials focussed on employees and provided sufficient information, which were included in the following meta-analysis. The results showed that LKCM benefited eight categories of workplace outcomes. Specifically, LKCM effectively decreased employees' burnout (g = 0.395, k = 10) and stress (g = 0.544, k = 10) and facilitated their mindfulness (g = 0.558, k = 14), self-compassion (g = 0.646, k = 12), personal mental health (g = 0.308, k = 13), job attitudes (g = 0.283, k = 4), interpersonal relationships (g = 0.381, k = 12), and psychological resources (g = 0.406, k = 6). The results of moderation analyses further indicated that the participants' job type, gender, and the focus of LKCM might differentially fluctuate the magnitude of LKCM effects. To advance research and best practice, we finally pointed out several issues that deserve attention, such as long-term effects, underlying mechanisms, potential moderators, and outcomes or influential factors at the organizational level.

Interparental Positivity Spillover Theory: How Parents' Positive Relational Interactions Influence Children

Interparental interactions have an important influence on child well-being and development. Yet prior theory and research have primarily focused on interparental conflict as contributing to child maladjustment, which leaves out the critical question of how interparental positive interactions-such as expressed gratitude, capitalization, and shared laughter-may benefit child growth and development. In this article, we integrate theory and research in family, relationship, and affective science to propose a new framework for understanding how the heretofore underexamined positive interparental interactions influence children: interparental positivity spillover theory (IPST). IPST proposes that, distinct from the influence of conflict, interparental positive interactions spill over into children's experiences in the form of their (a) experience of positive emotions, (b) beneficially altered perceptions of their parents, and (c) emulation of their parents' positive interpersonal behaviors. This spillover is theorized to promote beneficial cognitive, behavioral, social, and physiological outcomes in children in the short term (i.e., immediately after a specific episode of interparental positivity, or on a given day) as well as cumulatively across time. As a framework, IPST generates a host of novel and testable predictions to guide future research, all of which have important implications for the mental health, well-being, and positive development of children and families.

The Endogenous Opioid System as a Pathway of Positive Emotions

Pleasant emotions take a variety of forms and are a key part of the human experience. Although negative emotions have often been a focus of research, positive emotions, e.g., joy, pleasure, and love, have recently gained more attention. Each of these emotions is rich and complex in its own right. However, positive emotions appear to serve key evolutionary functions, which are mediated by complex biological substrates. This chapter summarizes key research and explores the biological underpinnings of positive emotions, with an emphasis on the roles that endogenous opioids play in the experience, expression, and development of positive emotions. The necessity of emphasizing positive emotions in research is also discussed.

Affect variability and physical health: The moderating role of mean affect

Research has only begun to explore how affect variability relates to physical health and has typically not assessed long-term associations nor considered the moderating role of mean affect. Therefore, we used data from the Midlife in the United States Study waves 2 (N = 1512) and 3 (N = 1499) to test how affect variability predicted concurrent and long-term physical health while also testing the moderating role of mean affect. Results indicated that greater negative affect variability was associated concurrently with a greater number of chronic conditions (p = .03) and longitudinally with worse self-rated physical health (p < .01). Greater positive affect variability was associated concurrently with more chronic conditions (p < .01) and medications (p < .01) and longitudinally with worse self-rated physical health (p = .04). Further, mean negative affect played a moderating role such that at lower levels of mean negative affect, as affect variability increased, so did the number of concurrent chronic conditions (p < .01) and medications (p = .03) and the likelihood of reporting worse long-term self-rated physical health (p < .01). Thus, the role of mean affect should be considered when testing short- and long-term associations between affect variability and physical health.

Getting closer: compassion training increases feelings of closeness toward a disliked person

Evidence-based interventions to favor more harmonious interactions in difficult relationships remain scarce. This study examined whether compassion training may have beneficial effects in an ongoing tense relationship with a disliked person, by reducing schadenfreude toward them and increasing felt interpersonal closeness. 108 participants were assigned to one of three 5-week trainings in a longitudinal randomized controlled study: compassion training, reappraisal training (emotion regulation control condition), or Italian language training (neutral active control condition). The disliked person was not targeted during the trainings to test potential transfer effects. Misfortune scenarios and a measure of interpersonal closeness were used to test whether schadenfreude and closeness feelings toward a disliked person changed from pre- to post-training, across different experimental and control groups. Only compassion and reappraisal trainees reported a decrease of schadenfreude feelings toward the disliked person compared to their pre-training ratings, no changes were observed in the Italian language training. Importantly, feelings of closeness toward the disliked person increased in the compassion training group compared to the other two groups. This increase of closeness feelings could be a central mechanism for improving social interactions. These transfer effects open new perspectives concerning emotion regulation interventions in conflict resolution.

Is Positive Affect as a Trait Related to Higher Heart Rate Variability in a Stressful Situation?

Most of the studies on the effect of trait positive affect (PA) and cardiovascular activity have focused on heart rate (HR) and blood pressure (BP) rather than heart rate variability (HRV). However, trait PA might sustain homeostasis for the autonomic system (ANS) by reducing activity in the sympathetic system (SNS) and increasing the activity in the parasympathetic system (PNS). A common index for the PNS is the vagal tone measured indirectly through HRV. The present study assessed whether trait PA influences cardiovascular response to various stress tasks by monitoring participants' HRV measured by RMSSD (root mean square of successive differences) along with HR and interbeat interval (IBI). A total of 54 participants performed various cognitive tasks and Trier Social Stress Tasks while their vital signs were monitored, and trait PA was measured with PANAS. The cognitive tasks included both high- and low-stress tasks, including fatigue-inducing 20 min Stroop tasks. The results showed overall higher HRV as measured by RMSSD for participants who have higher levels of trait PA, indicating more PNS activity compared with low-trait-PA individuals, particularly at the end of the task performance during the fatigue induction. High-trait-PA individuals also had a lower HR during the fatigue-inducing task and a higher IBI. The results support previous work by further indicating a more adaptive response and consequently better emotional regulation for high-trait-PA individuals in a complex, prolonged task setting.

Exploring friendship quality and the practice of savoring in relation to the wellbeing of Greek adults

Previous research findings demonstrate that both savoring ability and the presence of high-quality friendships play a significant role in enhancing one's overall sense of wellbeing. However, these associations have not been thoroughly investigated within a diverse range of adults across their lifespans, nor have they been explored in the specific cultural context of Greece. Thus, the primary objective of this study was to delve into the relationships between close friendship quality, the utilization of savoring techniques, and wellbeing within the Greek cultural framework. The study involved 771 adults from Greece with an average age of 38.35 years, who completed the McGill Friendship Functions Questionnaire, the PERMA Profiler, and the Abridged Ways of Savoring Checklist. Results revealed that there exists a positive correlation between friendship quality and savoring strategies with overall wellbeing. Moreover, the study identified a significant association wherein a greater employment of savoring strategies was linked to higher levels of friendship quality. While this study contributes valuable insights, it also has limitations that warrant acknowledgment. Furthermore, suggestions for potential future research directions are proposed, and the implications of these findings are discussed in relation to interventions aimed at enhancing both friendships and the practice of savoring across various contexts.

Autonomic nervous system flexibility for understanding brain aging

A recent call was made for autonomic nervous system (ANS) measures as digital health markers for early detection of Alzheimer's disease and related dementia (AD/ADRD). Nevertheless, contradictory or inconclusive findings exist. To help advance understanding of ANS' role in dementia, we draw upon aging and dementia-related literature, and propose a framework that centers on the role of ANS flexibility to guide future work on application of ANS function to differentiating the degree and type of dementia-related brain pathologies. We first provide a brief review of literature within the past 10 years on ANS and dementia-related brain pathologies. Next, we present an ANS flexibility model, describing how the model can be applied to understand these brain pathologies, as well as differentiate or even be leveraged to modify typical brain aging and dementia. Lastly, we briefly discuss the implication of the model for understanding resilience and vulnerability to dementia-related outcomes.

Psychophysiological stress response after a 6-week Mindful Self-Compassion training in psychiatric rehabilitation inpatients: a randomized post-test only study

Objectives

Mindfulness-based interventions (including self-compassion interventions) are effective in improving stress management at psychological and physical levels. Mindful Self-Compassion (MSC) is a newly developed program particularly aimed at increasing self-compassion. The main objective of this study was to determine whether the psychophysiological stress response during a social-evaluative speaking task differs in inpatients participating in the MSC or the Progressive Muscle Relaxation (PMR) program at the end of their 6-week psychiatric rehabilitation stay (i.e., post-test only design).

Method

Data from 50 inpatients (25 MSC, 25 PMR, 35 female) aged 19 to 76 years (M = 47.22, SD = 12.44) were analyzed in terms of psychophysiological stress response. For this purpose, heart rate variability, heart rate, and blood pressure were assessed together with several psychometric variables: positive and negative affect (PANAS), subjective stress perception (Visual Analog Scale), self-compassion (Self-Compassion Scale), cognitive reappraisal and suppression (Emotion Regulation Questionnaire), psychological distress (Brief Symptom Inventory-18), and appraisal and rumination (selected items).

Results

After correction for alpha inflation no differences in the psychophysiological stress response and psychometric parameters between the MSC and PMR group were found.

Discussion

In general, our results indicate that MSC is not superior to PMR training. However, more research with clinical randomized controlled trials investigating larger samples are needed to further affirm these initial findings.

Non-consciously processed physical activity for survival versus consciously deliberated exercise for health

Humans evolved to become dependent on physical activity for their survival, but they have not evolved to exercise today. Because survival in modern society is heavily reliant on conscious thinking, most people (54%) have evolved away from physical activity and become occasional exercisers. This transition from non-conscious to conscious processing prevents people from capitalizing on evolution's wisdom for survival and wellbeing as they consciously deliberate on the utility of health practices to achieve certain outcomes (e.g., weight loss). Unlike in early times, people today have a choice of not engaging in physical activity and yet surviving. As a result, they struggle with the question whether the gains from exercising are greater than losses from not doing it, weighing positive gains and losses against negative gains and losses. Such conscious deliberations, however, can easily be overridden by solving cognitive dissonance (e.g., "exercise is good for my health" vs. "I don't exercise") through conscious rationalizations and non-conscious dismissal. Today's exercise problem can only be solved by individually acquiring the mindset of early times of evolution when the initiation of physical activity was largely a matter of non-conscious thoughts and feelings.

Investigating the human chemical communication of positive emotions using a virtual reality-based mood induction

Humans can communicate their emotions to others via volatile emissions from their bodies. Although there is now solid evidence for human chemical communication of fear, stress and anxiety, investigations of positive emotions remain scarce. In a recent study, we found that women's heart rate and performance in creativity tasks were modulated by body odors of men sampled while they were in a positive vs. neutral mood. However, inducing positive emotions in laboratory settings remains challenging. Therefore, an important step to further investigate the human chemical communication of positive emotions is to develop new methods to induce positive moods. Here, we present a new mood induction procedure (MIP) based on virtual reality (VR), that we assumed to be more powerful than videos (used in our previous study) to induce positive emotions. We hypothesized that, consequently, given the more intense emotions created, this VR-based MIP would induce larger differences between the receivers' responses to the positive body odor versus a neutral control body odor, than the Video-based MIP. The results confirmed the higher efficacy of VR to induce positive emotions compared with videos. More specifically, VR had more repeatable effects between individuals. Although positive body odors had similar effects to those found in the previous video study, especially faster problem solving, these effects did not reach statistical significance. These outcomes are discussed as a function of the specificities of VR and of other methodological parameters, that may have prevented the observation of such subtle effects and that should be understood more in-depth for future studies on human chemical communication.

Creating mindful heroes: a case study with ninth grade students

The Heroic Imagination Project (HIP) aims to redefine heroism as a set of habits that anyone can achieve. Research findings on the psychological foundations of negative forms of social influence that can lead to bystander behavior are translated into tools that individuals can use in their daily lives. Habits of wise and effective helping behavior are learned, modeled, and encouraged through the training of the "heroic imagination." According to the literature, practicing mindfulness can increase empathy, compassion, and prosocial behaviors. There is empirical evidence that compassion can act as a mediator between mindfulness and prosocial helping behaviors toward strangers, suggesting that mindfulness promotes this behavior and thus helps to overcome the bystander effect. With this hypothesis in mind, we created a program that combined mindfulness and HIP sessions. Five participants volunteered to participate in the "Creating Mindful Heroes" 9-week program. Throughout the sessions, they filled in a diary, and at the end of the program, they answered two feedback questionnaires. They were then invited to participate in individual interviews. The participants reported a positive overall perspective regarding the program, mentioning several improvements in their relationships with their family, peers, and others in society. Moreover, participants reported that the program promoted prosocial behaviors and aided them in developing empathy.

Longitudinal association between N-terminal B-type natriuretic peptide, anxiety and social support in patients with HFpEF: results from the multicentre randomized controlled Aldo-DHF trial

BACKGROUND

Higher plasma levels of natriuretic peptides (NPs) have been associated with reduced anxiety in experimental research and a number of patient samples. As NP levels are elevated in heart failure patients, we investigate whether this elevation is related to anxiety in patients with heart failure with preserved ejection fraction (HFpEF).

METHODS

Post-hoc regression and mediation analyses were conducted, using data of 422 patients with HFpEF from the randomized, placebo-controlled, double-blinded, two-armed, multicentre aldosterone in diastolic heart failure trial, testing associations and their mediators between the N-terminal B-type natriuretic peptide (NT-proBNP) and anxiety at baseline and over 12-month follow-up. Anxiety was measured by the Hospital Anxiety and Depression Scale (HADS), social support by the ENRICHD Social Support Inventory and physical functioning by the Short Form 36 Health Survey.

RESULTS

The mean age of the study population was 66.8 ± 7.6 years, 47.6% were male and 86.0% had NYHA class II. NT-proBNP showed a weak negative correlation with HADS anxiety scores at baseline (r = - 0.087; p = 0.092), which was significant (r = - 0.165; p = 0.028) in men but not in women. NT-proBNP also tended to predict lower anxiety at 12-months in men. On the other hand, higher anxiety at baseline was associated with lower NT-proBNP scores 12 months later (r = - 0.116; p = 0.026). All associations lost significance in multivariate regression for age, perceived social support (ESSI), physical function (SF-36) and study arm. Mediation analyses revealed that social support acts as a full mediator for the link between NT-proBNP levels and anxiety.

CONCLUSION

The mechanisms linking NT-proBNP to anxiety may be more complex than originally assumed. While effects of NT-proBNP on anxiety may be mediated by perceived social support, there may be an additional negative effect of anxiety on NT-proBNP. Future research should consider this possible bi-directionality of the association and assess the potential influence of gender, social support, oxytocin and vagal tone on the interaction of anxiety and natriuretic peptide levels.

Development and psychometric study of the scale of the positive relationship PRIM + 19 in peruvian university students

BACKGROUND

Positive relationships are one of the most important components within the PERMA model since they facilitate the development of the other components. However, in the scientific literature, few instruments have been identified with solid psychometric properties that measure positive relationships in university students and adequately represent the construct. Therefore, the study aims to develop and study the psychometric properties of the PRI + 19 positive relationships scale through Confirmatory Factor Analysis, factorial invariance, and relationship-based validity with other variables.

METHOD

A pilot sample of 201 university students (43.8% men and 56.2 women) between the ages of 18 and 34 (M = 20.9; SD = 2.74) was collected. The confirmatory sample consisted of 450 university students of both sexes (30.2% men and 69.8 women) between the ages of 18 and 35 years (M = 21.9; SD = 3.15). Along with the PRI + scale, other instruments were applied to measure satisfaction with life and psychological well-being.

RESULTS

In the pilot study, the Exploratory Factor Analysis showed the presence of three factors that could explain 54.5% of the items. In the confirmatory study, the Confirmatory Factor Analysis showed that the model of three dimensions related to 19 items presents the best adjustment indexes compared to other models (χ2 = 541.61; df = 149; CFI = 0.97; TLI = 0.97; RMSEA = 0.077 [IC90% 0.070 ‒ 0.084]). The scale also showed evidence of being strictly invariant for the groups of men and women. Finally, it was shown that the development of the positive bonds dimension positively predicts psychological well-being (0.35) and life satisfaction (0.20). The positive relationship management dimension positively predicts psychological well-being (0.28) and life satisfaction (0.29). Similarly, the integration dimension positively predicts psychological well-being (0.48) and life satisfaction (0.52).

CONCLUSION

This study suggests that the PRIM + 19 scale is a useful tool from which valid and reliable interpretations of positive relationships in Peruvian university students can be obtained.

Awe as a Pathway to Mental and Physical Health

How do experiences in nature or in spiritual contemplation or in being moved by music or with psychedelics promote mental and physical health? Our proposal in this article is awe. To make this argument, we first review recent advances in the scientific study of awe, an emotion often considered ineffable and beyond measurement. Awe engages five processes-shifts in neurophysiology, a diminished focus on the self, increased prosocial relationality, greater social integration, and a heightened sense of meaning-that benefit well-being. We then apply this model to illuminate how experiences of awe that arise in nature, spirituality, music, collective movement, and psychedelics strengthen the mind and body.

Positive Psychology Interventions in Medical Populations: Critical Issues in Intervention Development, Testing, and Implementation

Positive psychological well-being is prospectively associated with superior health outcomes. Positive psychology interventions have promise as a potentially feasible and effective means of increasing well-being and health in those with medical illness, and several initial studies have shown the potential of such programs in medical populations. At the same time, numerous key issues in the existing positive psychology literature must be addressed to ensure that these interventions are optimally effective. These include (1) assessing the nature and scope of PPWB as part of intervention development and application; (2) identifying and utilizing theoretical models that can clearly outline potential mechanisms by which positive psychology interventions may affect health outcomes; (3) determining consistent, realistic targets for positive psychology interventions; (4) developing consistent approaches to the promotion of positive psychological well-being; (5) emphasizing the inclusion of diverse samples in treatment development and testing; and (6) considering implementation and scalability from the start of intervention development to ensure effective real-world application. Attention to these six domains could greatly facilitate the generation of effective, replicable, and easily adopted positive psychology programs for medical populations with the potential to have an important impact on public health.

Physiological response to self-compassion versus relaxation in a clinical population

BACKGROUND

Compassion-focused imagery (CFI) can be an effective emotion-regulation technique but can create threat-focused responses in some individuals. However, these findings have been based on tasks involving receiving compassion from others.

AIMS

This study sought to compare responses CFI involving self-compassion to relaxation and a control task, and to see whether any threat-responses to self-compassion and relaxation decrease with practice.

METHOD

25 participants with depression/anxiety symptoms and high self-criticism and/or low self-compassion engaged in three tasks (control task, relaxation imagery, and CFI) at three or four separate testing sessions, every three days. Heart-rate variability (HRV) was used to explore group-level differences between tasks. Additionally, we identified how many individuals showed a clinically significant change in HRV in response to compassion (compared to baseline) and how many showed such a change during relaxation (compared to baseline).

RESULTS

During session 1, more individuals had a clinically significant increase in HRV in response to CFI (56%) than in response to relaxation (44%), and fewer had a clinically significant decrease in HRV during CFI (16%) than during relaxation (28%). Comparing the group as a whole, no significant differences between tasks were seen. Repeated sessions led to fewer positive responses to CFI, perhaps reflecting habituation/boredom.

CONCLUSIONS

These preliminary findings suggest that in high self-critics (those most likely to find self-compassion difficult), self-compassionate imagery is no more challenging than standard relaxation tasks. For both compassion and relaxation, some individuals respond positively and others negatively. For those who are not benefiting, practice alone is not sufficient to improve response. Effects may differ for other compassion tasks.

Awe Sparks Prosociality in Children

Rooted in the novel and the mysterious, awe is a common experience in childhood, but research is almost silent with respect to the import of this emotion for children. Awe makes individuals feel small, thereby shifting their attention to the social world. Here, we studied the effects of art-elicited awe on children's prosocial behavior toward an out-group and its unique physiological correlates. In two preregistered studies (Study 1: N = 159, Study 2: N = 353), children between 8 and 13 years old viewed movie clips that elicited awe, joy, or a neutral (control) response. Children who watched the awe-eliciting clip were more likely to spend their time on an effortful task (Study 1) and to donate their experimental earnings (Studies 1 and 2), all toward benefiting refugees. They also exhibited increased respiratory sinus arrhythmia, an index of parasympathetic nervous system activation associated with social engagement. We discuss implications for fostering prosociality by reimagining children's environments to inspire awe at a critical age.

Electrodermal Activity Implicating a Sympathetic Nervous System Response under the Perception of Sensing a Divine Presence—A Psychophysiological Analysis

Previous studies have suggested that religious worship experiences may recruit the autonomic nervous system (ANS) in an activating fashion. For this reason, we hypothesized that measurements of the electrodermal activity (EDA) would concur with the notion that the subjective experience of sensing the presence of God recruits a sympathetic nervous system response. We analyzed the EDA of 37 evangelical participants and calculated classic galvanic skin response (GSR) measures. Our experimental design included six conditions with and without music consisting of religious and non-religious songs plus a resting-state condition, which were used to induce a variance in the religious experience suitable for statistical analyses. Results showed that both tonic and phasic signals as well as the overall electrical skin conductance (SC) were positively associated with the religious experience, defined as sensing the presence of God. This implicates that we can accept the hypothesis that such a religious experience under the influence of worship seems to recruit the sympathetic nervous system.

Adult friendship and wellbeing: A systematic review with practical implications

This study aimed to systematically review research findings regarding the relationship between adult friendship and wellbeing. A multidimensional scope for wellbeing and its components with the use of the PERMA theory was adopted. A total of 38 research articles published between 2000 and 2019 were reviewed. In general, adult friendship was found to predict or at least be positively correlated with wellbeing and its components. In particular, the results showed that friendship quality and socializing with friends predict wellbeing levels. In addition, number of friends, their reactions to their friend's attempts of capitalizing positive events, support of friend's autonomy, and efforts to maintain friendship are positively correlated with wellbeing. Efforts to maintain the friendship, friendship quality, personal sense of uniqueness, perceived mattering, satisfaction of basic psychological needs, and subjective vitality mediated this relationship. However, research findings highlighted several gaps and limitations of the existing literature on the relationship between adult friendship and wellbeing components. For example, for particular wellbeing components, findings were non-existent, sparse, contradictory, fragmentary, or for specific populations only. Implications of this review for planning and implementing positive friendship interventions in several contexts, such as school, work, counseling, and society, are discussed.

Examining affective reactivity as a link between suicidality and social disconnection

The link between suicidality and social disconnection is well-established. We explored possible mechanisms that may account for this link using a positive and negative valence systems framework in a clinical sample with and without suicidality (i.e., suicidal ideation and/or behaviors in the past month). Participants (N = 228) interacted with a trained confederate during a controlled conversation task designed to generate social affiliation. Participant-rated positive affect (PA) and negative affect (NA) were collected during the task (baseline, anticipation, post). Participant-rated desire for future interaction was collected after the task. We tested if (1) groups with (n = 82) and without (n = 146) suicidality differed in affect during the task and (2) whether affect accounted for the link between suicidality and desire for future interaction. Results revealed that groups differed in PA, but not NA, throughout the task. Participants with suicidality reported no significant changes in PA over the task (ps > .05); and, experienced less PA at post-task compared to those without (p = .003, d = 0.38) whereas participants without suicidality reported increased PA at post-task compared to baseline and anticipation of the task, ps < .001. Mediation analysis suggested blunted post-task PA accounted for the relationship between suicidality and less desire for future interaction, 95%CI [-2.59,-0.51]. Diminished PA reactivity during social affiliation opportunities may help explain the link between suicidality and social disconnection. Preliminary findings highlight PA as a potential mechanistic target for improving social connection for individuals at risk for suicide, though prospective and experimental research is needed.

Reward enhances resilience to chronic social defeat stress in mice: Neural ECs and mGluR5 mechanism via neuroprotection in VTA and DRN

INTRODUCTION

Stress often leads to emotional disorders such as depression. The reward might render this effect through the enhancement of stress resilience. However, the effect of reward on stress resilience under different intensities of stress needs more evidence, and its potential neural mechanism has been poorly revealed. It has been reported that the endogenous cannabinoid system (ECs) and downstream metabolic glutamate receptor 5 (mGluR5) are closely related to stress and reward, which might be the potential cerebral mechanism between reward and stress resilience, but there is a lack of direct evidence. This study aims to observe the effect of reward on stress resilience under different intensities of stress and further explore potential cerebral mechanisms underlying this effect.

METHODS

Using the chronic social defeat stress model, we applied reward (accompanied by a female mouse) under different intensities of stress in mice during the modeling process. The impact of reward on stress resilience and the potential cerebral mechanism were observed after modeling through behavioral tests and biomolecules.

RESULTS

The results showed that stronger stress led to higher degrees of depression-like behavior. Reward reduced depression-like behavior and enhanced stress resilience (all p-value <0.05) (more social interaction in the social test, less immobility time in the forced swimming test, etc.), with a stronger effect under the large stress. Furthermore, the mRNA expression levels of CB1 and mGluR5, the protein expression level of mGluR5, and the expression level of 2-AG (2-arachidonoylglycerol) in both ventral tegmental area (VTA) and dorsal raphe nucleus (DRN) were significantly upregulated by reward after modeling (all p-value <0.05). However, the protein expression of CB1 in VTA and DRN and the expression of AEA (anandamide) in VTA did not differ significantly between groups. Intraperitoneal injection of a CB1 agonist (URB-597) during social defeat stress significantly reduced depression-like behavior compared with a CB1 inhibitor (AM251) (all p-value <0.05). Interestingly, in DRN, the expression of AEA in the stress group was lower than that of the control group, with or without reward (all p-value <0.05).

DISCUSSION

These findings demonstrate that combined social and sexual reward has a positive effect on stress resilience during chronic social defeat stress, potentially by influencing the ECs and mGluR5 in VTA and DRN.

Time-out for well-being: A mixed methods evaluation of attitudes and likelihood to engage in different types of online emotional well-being programmes in the perinatal period

BACKGROUND

Positive maternal mental health during the perinatal period contributes to general well-being and positive emotional bonds with the child, encouraging an optimal developmental trajectory. Online interventions to enhance maternal well-being and develop coping skills, such as meditation-based interventions, can be a low-cost way to improve mother and child outcomes. However, this depends on end-user engagement. To date, there is limited evidence about women's willingness to engage and preferences for online programmes.

OBJECTIVES

This study explored pregnant women's attitudes towards and likelihood to undertake minimal online well-being training programmes (mindfulness, self-compassion, or general relaxation), engagement barriers and enablers, and programme structure preferences.

DESIGN

A mixed methods triangulation design was undertaken using a validating quantitative model. Quantile regressions were applied to the quantitative data. Content analysis was undertaken for the qualitative data.

METHODS

Consenting pregnant women (n = 151) were randomized equally to read about three online programme types. Participants were sent an information leaflet, tested by a consumer panel prior to distribution.

RESULTS

Participants generally held positive attitudes about all three types of interventions, with no statistically significant differences in preferences between programme types. Participants appreciated the importance of mental health and were receptive to fostering skills to support their emotional well-being and stress management. The most frequent perceived barriers were lack of time, tiredness, and forgetfulness. Programme structure preferences indicated one to two modules per week, less than 15 min in duration, and over 4 weeks. Programme functionality, such as regular reminders and easy accessibility, is important to end users.

CONCLUSION

Our findings reinforce the importance of determining participant preferences in designing and communicating engaging interventions for perinatal women. This research contributes to the understanding of population-based interventions that can be provided as simple, scalable, cost-effective, and home-based activities in pregnancy for the benefit of individuals, their families, and society more broadly.

Leisure and meaning in life

How people engage in leisure is an important but frequently underappreciated aspect of meaning in life. Leisure activities range from highly engaging and meaningful to subjectively trivial. Leisure itself is largely defined by meaning: The essence of leisure lies less in the specific activity than in the subjective perception of freedom, choice, and intrinsic motivation. People desire their lives to be meaningful, and leisure activities offer varying degrees of satisfying the basic needs for meaning (here covered as purpose, value, efficacy, and self-worth). Leisure activities vary along multiple conceptual dimensions, such as active vs. passive, seeking vs. escaping, solitary vs. interpersonal, and we consider the implications of these for meaningfulness. The most common leisure activity in modern society, watching television, encapsulates some of the paradoxes of leisure and meaningfulness. The study of how leisure enhances meaning in life is rich and ripe for future research.

The psychological and financial impacts of an emotional culture of anxiety and its antidote, an emotional culture of companionate love

RATIONALE

Anxiety is an increasingly common problem in society, including at work, yet the effects of an emotional culture of anxiety remain unexplored. We offer a new lens on anxiety in the workplace, examining its collective enactment in the form of an emotional culture of anxiety.

OBJECTIVE

This study examines the implications of an emotional culture of anxiety for psychological and financial outcomes within a poorly performing healthcare organization. We also examine whether an emotional culture of companionate love, which helps people "calm and connect", can counteract the negative effects of an emotional culture of anxiety.

METHODS

Drawing on survey data of 822 employees from 85 departments in a large US medical center and a time-lagged archival measure of financial performance across those departments, we used ordinary least squares regression and random coefficient regression modeling to examine the main effects of these two emotional cultures and the buffering effect of an emotional culture of companionate love on an emotional culture of anxiety for department costs, department psychological safety, and individual employee burnout and satisfaction.

RESULTS

We find significant direct relationships between an emotional culture of anxiety and an emotional culture of companionate love on employee burnout and satisfaction in the predicted directions. We also find a significant interaction between the two emotional cultures, with a culture of companionate love attenuating the relationship of a culture of anxiety on job satisfaction, burnout, and financial performance in the form of time-lagged department costs.

CONCLUSIONS

Our results indicate that a culture of companionate love can be a protective force against the negative outcomes of an emotional culture of anxiety. Examining these two emotional cultures concurrently offers a better understanding of how to address the pernicious effects of anxiety in organizations.

Effectiveness of a bite-sized web-based intervention to improve healthcare worker wellbeing: A randomized clinical trial of WISER

Importance

Problems with the wellbeing of healthcare workers (HCWs) are widespread and associated with detrimental consequences for the workforce, organizations, and patients.

Objective

This study tested the effectiveness of the Web-based Implementation for the Science of Enhancing Resilience (WISER) intervention, a positive psychology program, to improve six dimensions of the wellbeing of HCWs.

Design

We conducted a randomized controlled trial of HCWs between 1 April 2018 and 22 July 2019. Cohort 1 received WISER daily for 10 days. Cohort 2 acted as a waitlist control before receiving WISER.

Setting

Web-based intervention for actively employed HCWs across the United States.

Participants

Eligibility criteria included being ≥18 years old and working as a HCW. Each participant was randomized to start the intervention or serve as a waitlist control for 14 days before starting the intervention.

Interventions

Cohorts received links via 10 texts exposing them to introductory videos and positive psychology exercises (3 good things, cultivating awe, random acts of kindness, cultivating relationships, and gratitude letters).

Main outcomes and measures

The primary outcome was emotional exhaustion; secondary outcomes included depressive symptoms, work-life integration, happiness, emotional thriving, and emotional recovery. All outcomes were assessed at baseline, 1-week post-intervention (primary endpoint), and 1, 6, and 12-month post-intervention. Outcomes were measured using six validated wellbeing instruments, rescaled to 100-point scales for comparison. Six items assessed participants' WISER experience. The analysis employed mixed-effects models.

Results

In cohorts 1 and 2, 241 and 241 initiated WISER, and 178 (74%) and 186 (77%) completed the 6-month follow-up, respectively. Cohort populations were similar at baseline, mostly female (81; 76%) and nurses (34; 32%) or physicians (22; 23%), with 1-10 years of experience in their current position (54; 52%). Relative to control, WISER significantly improved depressive symptoms [-7.5 (95%CI: -11.0, -4.0), p < 0.001], work-life integration [6.5 (95%CI: 4.1, 8.9), p < 0.001], happiness [5.7 (95%CI: 3.0, 8.4), p < 0.001], emotional thriving [6.4 (95%CI: 2.5, 10.3), p = 0.001], and emotional recovery [5.3 (95%CI: 1.7, 8.9), p = 0.004], but not emotional exhaustion [-3.7 (95%CI: -8.2, 0.8), p = 0.11] at 1 week. Combined cohort results at 1, 6, and 12 months showed that all six wellbeing outcomes were significantly improved relative to baseline (p < 0.05 for all). Favorable impressions of WISER were reported by 87% of participants at the 6-month post-assessment.

Conclusion and relevance

WISER improved HCW depressive symptoms, work-life integration, happiness, emotional thriving, and emotional recovery. Improvements in all HCW wellbeing outcomes endured at the 1-, 6-, and 12-month follow-ups. HCW's impressions of WISER were positive.
