Emotional Contagion: A Brief Overview and Future Directions

The Relationship Between Dyadic Coping and Mental Health in Stroke Survivors and Their Spouse Caregivers: An Actor-Partner Interdependence Model

AIM

To investigate the relationship among dyadic coping, mental health and the individual and mutual influences on stroke survivors and their spouse caregivers.

DESIGN

A cross-sectional descriptive study was conducted in China from November 2019 to August 2020. The STROBE checklist was used to report the present study.

METHODS

The analysis included 224 dyads of stroke survivors and their spouse caregivers in China. Data on stroke survivors and their spouse caregivers were collected using the Dyadic Coping Inventory (DCI), the Patient Health Questionnaire nine-item scale (PHQ-9) and the Generalised Anxiety Disorder seven-item scale (GAD-7). The dyadic analysis was conducted based on the Actor-Partner Interdependence Model (APIM).

RESULTS

Regarding actor effects, spouse caregivers' dyadic coping and perceived dyadic coping had a negative predictive effect on their own anxiety and depression. Stroke survivors' perceived dyadic coping had a negative effect on their own depression. Regarding partner effects, spouse caregivers' perceived dyadic coping also had a negative predictive effect on the depression of the patients. In contrast, stroke survivors' perceived dyadic coping was positively associated with spouse caregivers' anxiety and depression. These findings suggested that mental health of stroke survivors and their spouse caregivers was affected by various dyadic coping dimensions.

CONCLUSIONS

Our research has the potential to contribute to the understanding dyadic coping and mental health of stroke survivor-spouse caregiver dyads. The findings reveal that the coping strategies employed by stroke couples are closely related to the mental health of both partners.

IMPACT

This study provides evidence for the significant impact of dyadic coping on the psychological well-being of stroke survivors and their spouse caregivers. Therefore, dyadic interventions aiming at strengthening dyadic coping may have positive effects on their mental health.

PATIENT OR PUBLIC CONTRIBUTION

This study directly involved the patients and family caregivers in hospital settings.

The association between teacher distress and student mental health outcomes: a cross-sectional study using data from the school mental health survey

BACKGROUND

Few studies have examined the inter-relationships between teacher and student mental health. We aimed to examine associations between teacher distress and student mental health difficulties and if student perceptions of school safety moderate these associations.

METHOD

Data from 23,568 students in grades 6-12 and 1,478 teachers from 268 schools participating in the School Mental Health Surveys in Ontario, Canada, were used. Three-level (student, classroom, school) multivariable linear regression models were fit to examine associations between teacher distress and student internalizing and externalizing symptoms by elementary (grades 6-8) and secondary (grades 9-12) school. Statistical interactions were used to evaluate effect modification.

RESULTS

Small but statistically significant, positive associations were found between teacher distress and internalizing (b = 0.02; 95% CI [0.01, 0.04], p < 0.05) and externalizing symptoms (b = 0.03; 95% CI [0.01, 0.05], p < 0.001) among elementary students only. Student perceptions of school safety moderated the association between teacher distress and externalizing symptoms among elementary students, whereby the positive association was magnified among students reporting lower school safety.

CONCLUSIONS

Findings from this study highlight the importance of concurrently addressing the mental health needs of educators and students. School safety represents a modifiable target for prevention and intervention efforts in schools that could serve to promote student mental health and mitigate potential risk factors in schools.

Living the good life? A systematic review of behavioural signs of affective state in the domestic horse (Equus caballus) and factors relating to quality of life. Part 2: Horse-human interactions

Quality of life is dependent upon the extent to which behavioural needs are met, and the balance between pleasant and unpleasant lifetime experiences. In Part II of this systematic review, articles (n = 109) relating to horse-human interactions were reviewed to identify behavioural evidence of their positive or negative impact on the horse. The number of articles (n = 22) relating to the recognition of pain in horses, indicated the importance of identifying health issues, which are also likely to increase the aversiveness of interactions. These and articles relating to emotional reactivity testing in horses (n = 19), the behaviour of horses during handling and management procedures (n = 17), behaviour of the horse when ridden (n = 17), non-procedural horse-human interactions (n = 13), horse behaviour during transportation (n = 12) and behaviour during training other than when ridden (n = 9) were reviewed. During most interactions, horse behaviour is controlled and/or restricted by the human, masking negative or positive signs, and may be confounded by factors including fear and individual differences. In situations involving freedom of movement, positive experiences of horses with humans were associated with approach behaviour, negative ones with avoidance, but training could affect both. Undoubtedly, change is needed to reduce the extent to which interactions with humans are unpleasant for the horse. Only when the needs of the horse are fulfilled and interactions with humans are predominantly pleasurable will their quality of life improve.

The relationship between social odour awareness and emotional contagion susceptibility in females

Previous research has shown a strong link between our sense of smell and emotion. More recently, the importance we attach to olfaction has been found to relate to our susceptibility to 'catch' the emotions of others. We explore this further by examining the relation between a newly developed measure of olfaction (social odour scale, SOS), which measures awareness of social odours, and emotional contagion susceptibility in female participants. The study therefore aimed to test the strength of this relationship and also help validate the English language version of the SOS. Female (n = 148) participants completed an online study that measured odour awareness [SOS; important of odour questionnaire, IOQ] and emotional contagion (EC). We found that the English version of the SOS yielded high reliability and supported the previous factor structure of the scale; additionally, we demonstrated a strong association between the SOS and IOQ which provides criterion validity for its usage. The study also revealed that whilst both the SOS and IOQ were positively associated with EC, the SOS was the more accurate predictor. These findings provide further validation for the use of the SOS and suggest that our subjective awareness of olfaction, especially concerning 'social odours' is an accurate predictor of emotional contagion.

Emotional Contagion and Emotional Mimicry in Individuals with Schizophrenia: A Systematic Review

Background: Individuals with schizophrenia often exhibit social interaction deficits, which can affect their ability to engage effectively with others. Emotional processes, such as emotional contagion (the transfer of emotion between individuals) and emotional mimicry (the imitation of emotional expressions), are crucial for enhancing the quality of social interactions. Methods: We conducted a PubMed, Web of Science, and PsycInfo database search. The inclusion and exclusion criteria were established based on the definitions of emotional contagion and emotional mimicry, rather than relying on specific terminology from various research fields. Forty-two studies were included in the review, including six emotional mimicry studies and thirty-six emotional contagion studies. Results: The current findings suggest decreased or inappropriate emotional mimicry in individuals with schizophrenia. Relating to emotional contagion, the results showed altered brain and psychophysiological activity in individuals with schizophrenia, whereas the self-reported measures indicated no difference between the groups. The relationships between emotional contagion, emotional mimicry, and psychotic symptom severity showed variability across the studies, whereas no associations between antipsychotic dosage and either emotional mimicry or emotional contagion were found. Discussion: This review highlights the need to further evaluate and train emotional contagion and emotional mimicry in individuals with schizophrenia because these processess influence social interaction quality. Clinical implications and guidelines for future studies are discussed.

How Teachers' Emotional Leadership Influences College Students' Learning Engagement

Teachers' emotional leadership plays a crucial role in influencing college students' learning engagement. This study, grounded in Affective Events Theory, surveyed 1034 Chinese college students (649 females and 385 males) to examine their perceptions of teachers' emotional leadership, achievement emotions, emotional susceptibility, and learning engagement. The findings reveal that teachers' emotional leadership has a significant positive impact on college students' learning engagement. Specifically, college students' achievement emotions mediate the relationship between teachers' emotional leadership and their learning engagement. Additionally, college students' emotional susceptibility moderates the relationship between teachers' emotional leadership and their achievement emotions; however, it does not moderate the impact of teachers' emotional leadership on learning engagement through achievement emotions. This study validates the application of Affective Events Theory in the educational field, deepens the understanding of the mechanism and boundary conditions of emotional leadership's impact on learning engagement, and offers insights for enhancing college students' learning engagement.

Emotional contagion and prosocial behaviour in fish: An evolutionary and mechanistic approach

In this review, we consider the definitions and experimental approaches to emotional contagion and prosocial behaviour in mammals and explore their evolutionary conceptualisation for studying their occurrence in the evolutionarily divergent vertebrate group of ray-finned fish. We present evidence for a diverse set of fish phenotypes that meet definitional criteria for prosocial behaviour and emotional contagion and discuss conserved mechanisms that may account for some preserved social capacities in fish. Finally, we provide some considerations on how to address the question of interdependency between emotional contagion and prosocial response, highlighting the importance of recognition processes, decision-making systems, and ecological context for providing evolutionary explanations.

Threat-induced prosocial behavior: enhanced exogenous attention to protect others from harm

As social animals, humans tend to voluntarily engage in pro-social behavior to prevent harm to others. However, to what extent prosocial behavior can be reflected at the level of less voluntary cognitive processes remains unclear. Here, we examined how threat to others modulates exogenous attention. Fifty-four participants performed an exogenous spatial cueing task where the participant's performance determined whether electric shocks would be delivered either to themselves or to their anonymous co-participant. Threat of shock to the co-participant elicited orienting and reorienting responses that were faster than in the safe condition and did not differ from performance when participants avoided shocks to themselves. This attentional improvement was not due to speed-accuracy trade off and was associated with arousal, i.e., increased pupil dilation in both threat conditions. Together, these findings suggest that pro-social behavior triggers automatic attentional processes which may be relevant for providing immediate help without relying on reflexive processes.

The role of self-representation in emotional contagion

Although prior research has implied that emotional contagion occurs automatically and unconsciously, convincing evidence suggests that it is significantly influenced by individuals' perceptions of their relationships with others or with collectives within specific social contexts. This implies a role for self-representation in the process. The present study aimed to offer a novel explanation of the interplay between social contexts and emotional contagion, focusing on the contextualized nature of self-representation and exploring the social factors that shape emotional contagion. It further posits a causal loop among social contexts, self-representation, and emotional contagion. Drawing from the lens of self-representation, this study concludes with a discussion on potential research directions in this field, commencing with an exploration of the antecedents and consequences of emotional contagion and self-representation.

Rapid facial mimicry in Platyrrhini: Play face replication in spider monkeys (Ateles fusciceps, Ateles hybridus, and Ateles paniscus)

Rapid facial mimicry (RFM), the rapid and automatic replication of facial expression perceived, is considered a basic form of empathy and was investigated mainly during play. RFM occurs in Catarrhini (Old World primates), but it is not still demonstrated in Platyrrhini (New World primates). For this reason, we collected video data on playful interactions (Nplay_interactions = 149) in three species of spider monkeys (Ateles fusciceps-N = 11, Ateles hybridus-N = 14, and Ateles paniscus-N = 6) housed at La Vallée des Singes and the ZooParc de Beauval (France). For the first time, we demonstrated the occurrence of RFM in Platyrrhini (analyzing 175 events). Players' sex, age, species, relationship quality, and kinship did not modulate RFM probably due to the species' complex fission-fusion dynamics and flexible interindividual social relationships. Compared to the absence of any playful expressions or the presence of only not replicated play face, RFM prolonged the session duration and was sequentially associated with more types of more intense offensive playful patterns (patterns aimed at attacking/pursuing the playmate). We proposed that RFM may favor synchronization and context sharing between players, thus decreasing the risk of behavior misinterpretation while simultaneously fostering a more competitive nature of play. In conclusion, this study stimulates additional research on the evolutionary origins of motor mimicry in primates, possibly dating back to before the divergence of New and Old World monkeys. Furthermore, it also points toward the possibility that RFM may not always lead to cooperation but also to competition, depending on the context and species' social and cognitive features.

How does the UK public think and feel about people with visual impairment: a review of existing evidence

Despite legislation to protect people with visual impairment (V.I.) from discrimination in the United Kingdom (UK), the latter continue to experience overt and covert negative behaviours. Perceived discrimination has been associated with an adverse impact on identity, health and well-being, while negative attitudes have been identified as the biggest barrier to participation in everyday life. This article provides a narrative review of existing evidence of how the UK public treats (behaviours), thinks (perceptions) and feels (attitudes) about people with V.I. Despite limitations, the findings suggest that there is a gap between the behaviours reported by people with V.I. and the attitudes expressed by members of the UK public. Social psychological theories are used to explore possible reasons for this gap, and ways in which it may be addressed. As such, the article provides an example of how social psychological theories can be used to address problems in an applied context.

The impact of toxic trolling comments on anti-vaccine YouTube videos

Anti-vaccine trolling on video-hosting websites hinders efforts to increase vaccination rates by using toxic language and threatening claims to intimidate people and promote vaccine hesitancy. However, there is a shortage of research investigating the effects of toxic messages on these platforms. This study focused on YouTube anti-vaccine videos and examined the relationship between toxicity and fear in the comment section of these videos. We discovered that highly liked toxic comments were associated with a significant level of fear in subsequent comments. Moreover, we found complex patterns of contagion between toxicity and fear in the comments. These findings suggest that initial troll comments can evoke negative emotions in viewers, potentially fueling vaccine hesitancy. Our research bears essential implications for managing public health messaging and online communities, particularly in moderating fear-mongering messages about vaccines on social media.

Feeling Alone Together: Loneliness in Older Adults with Cognitive Impairment and Their Family Caregivers with Low Mastery

INTRODUCTION

Loneliness in older persons with cognitive impairment (PCI) may beget loneliness in their family caregivers, depending on buffering resources caregivers possess. This study examined the association between loneliness in older PCI and loneliness experienced by their family caregivers, and the moderating role of caregiver mastery in this association.

METHODS

Dyadic data from 135 PCI and their family caregivers in Singapore were analyzed using multivariable regression. Loneliness was measured using a three-item UCLA loneliness scale. Mastery was assessed using a seven-item Pearlin instrument.

RESULTS

Multivariable regression showed that PCI loneliness and caregiver loneliness were weakly associated, taking other covariates into account. Notably, a significant interaction between PCI loneliness and caregiver mastery was observed, indicating that PCI loneliness was associated with caregiver loneliness only when caregivers had low mastery.

CONCLUSION

Lonely PCI may share their feelings of loneliness with their caregivers, and this can lead to loneliness among caregivers if they have low mastery. Promoting caregiver mastery may help reduce caregiver loneliness, directly and indirectly as a buffer against PCI loneliness.

A Relaxed Horse-A Relaxed Client? An Experimental Investigation of the Effects of Therapy Horses' Stress on Clients' Stress, Mood, and Anxiety

Equine-assisted therapies are becoming increasingly popular for addressing physical and psychological disabilities in clients. The role of the horse's welfare in equine-assisted service receives increasing attention in research. Several studies have shown that horses are able to perceive human emotions and respond to human stress responses. However, no research has yet looked at the other side of the coin-whether and how humans perceive and react to equine stress levels during equine-assisted services. To fill this gap in the research, we employed a within-subjects design, in which horse-naïve participants had a standardized interaction with both an experimentally stressed horse and an experimentally relaxed horse. We assessed physiological indicators of stress (heart rate, heart rate variability, and salivary cortisol) in participants and horses, as well as psychological indicators of stress (state anxiety and positive and negative affect) in participants. Although our stress and relaxation manipulations were successful (indicated by horses' physiological indicators of stress), we did not find any difference in the participants' physiological or psychological indicators of stress between the interaction with a stressed and the interaction with a relaxed horse. Together with results from previous studies, this suggests that humans cannot intuitively recognize the (physiological) stress level of horses, which has important implications for effective communication and bonding between humans and horses and for the safety of equine activities.

Exploring the impact of pediatric short bowel syndrome on parent well-being using a disease-specific pilot survey

BACKGROUND

Children with short bowel syndrome (SBS) have complex care needs, most of which are met in the home by family caregivers who may experience a range of stressors unique to this experience. Prior research suggests that parents of children with SBS have poorer health-related quality of life than peers parenting children without health needs, but the mechanisms shaping parent outcomes are understudied.

METHODS

A pilot survey was developed using a community-driven research design to measure the impact of disease-specific items on parent-perceived well-being. The cross-sectional survey, which included both closed-ended and open-ended items, was distributed to a convenience sample of parents of children with SBS. Quantitative and qualitative data were integrated for a mixed-methods analysis of how individual items impacted parent well-being.

RESULTS

Twenty parents completed the survey. Sleep interruptions, lack of support and resources, and psychological stressors and their mental health implications were more frequently reported as stressors than logistics related to caregiving (e.g., managing therapies and preparing specialized meals).

CONCLUSION

The impact of a child's SBS on parent well-being may stem mainly from three interconnected domains: poor sleep and its consequences, lack of access to support and resources, and a range of psychological stressors that affect parent mental health. Understanding the mechanisms through which SBS shapes parent well-being is a necessary first step for developing targeted interventions to support parents and provide family-centered care.

Not all #complaints are equally contagious: an Instagram experiment

Instagram has been perceived as the least appropriate platform to express negativity online, yet the number of posts tagged under #complain, #complaint, #complaints, and #complaining are increasing. We conducted a controlled web-based experiment to examine the extent to which exposure to other's quotes of complaints contributed to increased similarity in emotions for the audience (i.e., digital emotion contagion). Participants (n = 591 Instagram users in Indonesia; 82.23% females; Mage = 28.06, SD = 6.39) were randomly assigned to exposure of complaint quotes containing seven basic emotions. We found that exposure to three of the five complaint quotes (i.e., anger, disgust, and sadness) induced similar emotions in the participants while the two other complaint quotes (i.e., fear and anxiety) induced overlapping emotions, but a non-complaint quote (i.e., desire and satisfaction) induced alternative emotions. Taken together, digital emotion contagion was likely produced by exposure to complaint quotes, while exposure to non-complaint quotes induced different, possibly complementary-like, emotions. Although these findings should be considered as a snapshot of the complex emotional dynamics online, it highlights that exposure to simple Instagram quotes has the potential to go beyond mere contagion.

Leveraging stylometry analysis to identify unique characteristics of peer support user groups in online mental health forums

Online peer support mental health forums provide an effective and accessible form of support, augmenting scarce clinical and face-to-face assistance. However, to enhance their effectiveness, it is essential to understand the unique characteristics of peer support user groups, and how they participate, contribute and communicate in these forums. This paper proposes and tests a novel approach that leverages stylometry analysis to uncover the unique characteristics of peer support user groups in such forums. Our approach identifies how each group empowers and supports other users, and what distinguishes them from others. The analysis shows that emotion-related words are crucial in identifying and distinguishing user groups based on their writing style. Comparative analysis of emotion expressions across user groups also uncovers the significance of emotional content in these forums in promoting mental well-being. Valued 'senior contributors' were more likely than all other groups including trained community guides to use a wide range of both positive and negative emotions in their posts. These findings have significant implications for improving the training of peer-mentors and moderators, scaling forum services, and improving guidelines for emotional expression among peer support users. Our approach presents an objective approach to differentiating the characteristics and communication patterns of valued senior contributors, mentors, and guides, enabling service providers to foster the kinds of communication that supports positive outcomes for distressed users.

Distinct ACC Neural Mechanisms Underlie Authentic and Transmitted Anxiety Induced by Maternal Separation in Mice

It is known that humans and rodents are capable of transmitting stress to their naive partners via social interaction. However, a comprehensive understanding of transmitted stress, which may differ from authentic stress, thus revealing unique neural mechanisms of social interaction resulting from transmitted stress and the associated anxiety, is missing. We used, in the present study, maternal separation (MS) as a stress model to investigate whether MS causes abnormal behavior in adolescence. A key concern in the analysis of stress transmission is whether the littermates of MS mice who only witness MS stress ("Partners") exhibit behavioral abnormalities similar to those of MS mice themselves. Of special interest is the establishment of the neural mechanisms underlying transmitted stress and authentic stress. The results show that Partners, similar to MS mice, exhibit anxiety-like behavior and hyperalgesia after witnessing littermates being subjected to early-life repetitive MS. Electrophysiological analysis revealed that mice subjected to MS demonstrate a reduction in both the excitatory and inhibitory synaptic activities of parvalbumin interneurons (PVINs) in the anterior cingulate cortex (ACC). However, Partners differed from MS mice in showing an increase in the number and excitability of GABAergic PVINs in the ACC and in the ability of chemogenetic PVIN inactivation to eliminate abnormal behavior. Furthermore, the social transfer of anxiety-like behavior required intact olfactory, but not visual, perception. This study suggests a functional involvement of ACC PVINs in mediating the distinct neural basis of transmitted anxiety.SIGNIFICANCE STATEMENT The anterior cingulate cortex (ACC) is a critical brain area in physical and social pain and contributes to the exhibition of abnormal behavior. ACC glutamatergic neurons have been shown to encode transmitted stress, but it remains unclear whether inhibitory ACC neurons also play a role. We evaluate, in this study, ACC neuronal, synaptic and network activities and uncover a critical role of parvalbumin interneurons (PVINs) in the expression of transmitted stress in adolescent mice who had witnessed MS of littermates in infancy. Furthermore, inactivation of ACC PVINs blocks transmitted stress. The results suggest that emotional contagion has a severe effect on brain function, and identify a potential target for the treatment of transmitted anxiety.

A multilayered graph-based framework to explore behavioural phenomena in social media conversations

OBJECTIVE

Social media is part of current health communications. This research aims to delve into the effects of social contagion, biased assimilation, and homophily in building and changing health opinions on social media.

MATERIALS AND METHODS

Conversations about COVID-19 vaccination on English and Spanish Twitter are the case studies. A new multilayered graph-based framework supports the integrated analysis of content similarity within and across posts, users, and conversations to interpret contrasting and confluent user stances. Deep learning models are applied to infer stance. Graph centrality and homophily scores support the interpretation of information reproduction.

RESULTS

The results show that semantically related English posts tend to present a similar stance about COVID-19 vaccination (rstance = 0.51) whereas Spanish posts are more heterophilic (rstance = 0.38). Neither case showed evidence of homophily regarding user influence or vaccine hashtags. Graph filters for Pfizer and Astrazeneca with a similarity threshold of 0.85 show stance homophily in English scenarios (i.e. rstance = 0.45 and rstance = 0.58, respectively) and small homophily in Spanish scenarios (i.e. r = 0.12 and r = 0.3, respectively). Highly connected users are a minority and are not socially influential. Spanish conversations showed stance homophily, i.e. most of the connected conversations promote vaccination (rstance = 0.42), whereas English conversations are more likely to offer contrasting stances.

CONCLUSION

The methodology proposed for quantifying the impact of natural and intentional social behaviours in health information reproduction can be applied to any of the main social platforms and any given topic of conversation. Its effectiveness was demonstrated by two case studies describing English and Spanish demographic and sociocultural scenarios.

Psychometric properties and factor structure of the Revised Beliefs About Emotions Questionnaire

OBJECTIVE

Given that there is an increasing exploration of the role of beliefs about emotions in emotion regulation and psychotherapy, there is a need for a range of valid and reliable measures of beliefs about emotions. The Beliefs About Emotions Questionnaire (BAEQ) has been shown to be a promising measure of beliefs about emotions. However, to date, no study has attempted to replicate the original factor structure of the BAEQ in an English-speaking country. The present study examined the psychometric properties of the BAEQ in a nonclinical sample.

METHOD

Archival data of 1807 adult participants residing in Australia was divided into three equal groups of participants. A confirmatory factor analysis (CFA) was conducted on the first sub-sample, an exploratory factor analysis (EFA) was performed on the second sub-sample, and a second CFA was performed on the third sub-sample. Divergent validity was tested using the heterotrait-monotrait ratio and the concurrent validity was tested through correlations with the subscales of the Three-Factor Eating Questionnaire (TFEQ-R18).

RESULTS

The first CFA failed to replicate the original factor structure of the BAEQ. An EFA supported five of the original six factors. A five-factor structure, including 30 out of the original 43 items, was confirmed in a second CFA. The final subscales (Shameful and Irrational, Overwhelming and Uncontrollable, Invalid and Meaningless, Useless and Damaging) demonstrated good construct validity, good internal consistency, and good concurrent and divergent validity.

CONCLUSION

The results from this study support a briefer five-factor, 30-item version of the BAEQ (BAEQ-R) as a reliable and valid measure of beliefs about emotions that can be utilised in future research.

A scalable and robust system for audience EEG recordings

The neural mechanisms that unfold when humans form a large group defined by an overarching context, such as audiences in theater or sports, are largely unknown and unexplored. This is mainly due to the lack of availability of a scalable system that can record the brain activity from a significantly large portion of such an audience simultaneously. Although the technology for such a system has been readily available for a long time, the high cost as well as the large overhead in human resources and logistic planning have prohibited the development of such a system. However, during the recent years reduction in technology costs and size have led to the emergence of low-cost, consumer-oriented EEG systems, developed primarily for recreational use. Here by combining such a low-cost EEG system with other off-the-shelve hardware and tailor-made software, we develop in the lab and test in a cinema such a scalable EEG hyper-scanning system. The system has a robust and stable performance and achieves accurate unambiguous alignment of the recorded data of the different EEG headsets. These characteristics combined with small preparation time and low-cost make it an ideal candidate for recording large portions of audiences.

Predictors of psychoneurological symptoms in cancer caregivers over time: Role of caregiving burden, stress, and patient symptoms

PURPOSE

In cancer patients, stress is associated with a psychoneurologic (PN) symptom cluster of depressed mood, anxiety, pain, fatigue, and sleep disturbance. The stress of caregiving may trigger similar symptoms among caregivers and warrants investigation. The purpose of this analysis was to characterize correlates of PN symptom burden in cancer caregivers.

METHODS

Cancer patient-caregiver dyads (n = 29) provided eight weekly symptom reports using a web-based survey. Primary and secondary stressors of caregiving were also assessed. Mixed models accounting for repeated measurement were used to assess the between- and within-dyad predictors of caregiver PN symptom burden. The interaction of patient PN symptom burden and stress was tested. Exploratory cross-lagged Actor-Partner Interdependence Models were used to assess the week-to-week interdependence between patient and caregiver symptoms.

RESULTS

Caregivers most frequently reported feeling anxious (44% on average across timepoints), sleep problems (31%), fatigue (25%), and depressed mood (24%). Mixed models indicated that within dyads, greater hours of care and more patient symptoms were associated with greater caregiver PN symptom burden. Greater baseline perceived stress was also associated with higher caregiver PN symptom burden and moderated the association between patient and caregiver PN symptom burden. Cross-lagged Actor-Partner Interdependence Models indicated longitudinal interdependence among survivor and caregiver symptom burden.

CONCLUSIONS

The findings provide preliminary evidence of the interrelationship of PN symptom burden in caregivers and patients and the potential for stress to amplify this interrelationship, with implications for symptom management and supportive care practice.

A theoretical approach to improving interspecies welfare comparisons

The number of animals bred, raised, and slaughtered each year is on the rise, resulting in increasing impacts to welfare. Farmed animals are also becoming more diverse, ranging from pigs to bees. The diversity and number of species farmed invite questions about how best to allocate currently limited resources towards safeguarding and improving welfare. This is of the utmost concern to animal welfare funders and effective altruism advocates, who are responsible for targeting the areas most likely to cause harm. For example, is tail docking worse for pigs than beak trimming is for chickens in terms of their pain, suffering, and general experience? Or are the welfare impacts equal? Answering these questions requires making an interspecies welfare comparison; a judgment about how good or bad different species fare relative to one another. Here, we outline and discuss an empirical methodology that aims to improve our ability to make interspecies welfare comparisons by investigating welfare range, which refers to how good or bad animals can fare. Beginning with a theory of welfare, we operationalize that theory by identifying metrics that are defensible proxies for measuring welfare, including cognitive, affective, behavioral, and neuro-biological measures. Differential weights are assigned to those proxies that reflect their evidential value for the determinants of welfare, such as the Delphi structured deliberation method with a panel of experts. The evidence should then be reviewed and its quality scored to ascertain whether particular taxa may possess the proxies in question to construct a taxon-level welfare range profile. Finally, using a Monte Carlo simulation, an overall estimate of comparative welfare range relative to a hypothetical index species can be generated. Interspecies welfare comparisons will help facilitate empirically informed decision-making to streamline the allocation of resources and ultimately better prioritize and improve animal welfare.

Current Perspectives on the Challenges of Implementing Assistance Dogs in Human Mental Health Care

The prevalence of mental health disorders, driven by current global crises, is notably high. During the past decades, the popularity of dogs assisting humans with a wide spectrum of mental health disorders has significantly increased. Notwithstanding these dogs' doubtless value, research on their legal status, certification processes, training and management practices, as well as their welfare status, has been scarce. This scoping review highlights that in contrast to other assistance dogs such as guide dogs, there exists no consistent terminology to mark dogs that assist humans with impaired mental health. Legal authorities monitoring the accreditation process, training and tracking of mental health supporting dogs are broadly lacking, with only few exceptions. This review emphasizes the need to address several topics in the promotion of progress in legal and welfare issues related to assistance dogs as well as emotional support dogs for humans with a mental health disorder. The current body of knowledge was assessed in three different areas of focus: (1) the legal dimension including definitions and certification processes; (2) the dimension of performed tasks; and (3) the dog welfare dimension including aspects of the relationship with the handler and risks associated with children recipients. Considering the challenges associated with a mental health diagnosis, collaborations of dog provider organizations and health care professionals would be desirable to continuously assess the efficiency of the human-dog dyad regarding their overall compatibility, general satisfaction and mutual well-being.

Living on the edge: How to prepare for it?

Introduction

Isolated, confined, and extreme (ICE) environments such as found at Antarctic, Arctic, and other remote research stations are considered space-analogs to study the long duration isolation aspects of operational space mission conditions.

Methods

We interviewed 24 sojourners that participated in different short/long duration missions in an Antarctic (Concordia, Halley VI, Rothera, Neumayer II) or non-Antarctic (e.g., MDRS, HI-SEAS) station or in polar treks, offering a unique insight based on first-hand information on the nature of demands by ICE-personnel at multiple levels of functioning. We conducted a qualitative thematic analysis to explore how sojourners were trained, prepared, how they experienced the ICE-impact in function of varieties in environment, provided trainings, station-culture, and type of mission.

Results

The ICE-environment shapes the impact of organizational, interpersonal, and individual working- and living systems, thus influencing the ICE-sojourners' functioning. Moreover, more specific training for operating in these settings would be beneficial. The identified pillars such as sensory deprivation, sleep, fatigue, group dynamics, displacement of negative emotions, gender-issues along with coping strategies such as positivity, salutogenic effects, job dedication and collectivistic thinking confirm previous literature. However, in this work, we applied a systemic perspective, assembling the multiple levels of functioning in ICE-environments.

Discussion

A systemic approach could serve as a guide to develop future preparatory ICE-training programs, including all the involved parties of the crew system (e.g., family, on-ground crew) with attention for the impact of organization- and station-related subcultures and the risk of unawareness about the impact of poor sleep, fatigue, and isolation on operational safety that may occur on location.

Gaze behavior in social interactions between beach volleyball players—An exploratory approach

Previous research has indicated that social interactions and gaze behavior analyses in a group setting could be essential tools in accomplishing group objectives. However, only a few studies have examined the impact of social interactions on group dynamics in team sports and their influence on team performance. This study aimed to investigate the effects of game performance pressure on the gaze behavior within social interactions between beach volleyball players during game-like situations. Therefore, 18 expert beach volleyball players conducted a high and a low game performance pressure condition while wearing an eye tracking system. The results indicate that higher game performance pressure leads to more and longer fixation on teammates’ faces. A higher need for communication without misunderstandings could explain this adaptation. The longer and more frequent look at the face could improve the receiving of verbal and non-verbal information of the teammate’s face. Further, players showed inter-individual strategies to cope with high game performance pressure regarding their gaze behavior, for example, increasing the number of fixations and the fixation duration on the teammate’s face. Thereby, this study opens a new avenue for research on social interaction and how it is influenced in/through sport.

Testing spillover-crossover effects of work-family conflict and family-work conflict on Indonesian spouses

Purpose

This study aims to investigate the spillover–crossover effects on the work–family interface, with an emphasis on work–family conflict (WFC) and family–work conflict (FWC) on marital satisfaction and personal burnout.

Design/methodology/approach

Data were collected from matched dyads by 300 teachers and their spouses (N = 600) in Indonesia. Multiple regression analysis served to test the hypotheses.

Findings

The results showed significant spillover–crossover effects of WFC on personal burnout amongst working wives to their spouses, but not working husbands to their spouses. Moreover, there was a spillover effect of FWC on personal burnout amongst working wives, and a crossover effect of FWC on spouses' personal burnout amongst working husbands to their spouses. However, there was no spillover–crossover effect of WFC and FWC on marital satisfaction for both working wives and husbands.

Practical implications

The findings have implications for occupational stress management. Decision-makers have to create a positive atmosphere that reduces WFC in the workplace by providing support to the workers.

Originality/value

This study contributes to the literature by exploring the crossover effects of WFC and FWC amongst marital spouses in a country with inherent conservatism and traditional gender role perspectives.

Enhanced Mirror Neuron Network Activity and Effective Connectivity during Live Interaction Among Female Subjects

Facial expressions are indispensable in daily human communication. Previous neuroimaging studies investigating facial expression processing have presented pre-recorded stimuli and lacked live face-to-face interaction. Our paradigm alternated between presentations of real-time model performance and pre-recorded videos of dynamic facial expressions to participants. Simultaneous functional magnetic resonance imaging (fMRI) and facial electromyography activity recordings, as well as post-scan valence and arousal ratings were acquired from 44 female participants. Live facial expressions enhanced the subjective valence and arousal ratings as well as facial muscular responses. Live performances showed greater engagement of the right posterior superior temporal sulcus (pSTS), right inferior frontal gyrus (IFG), right amygdala and right fusiform gyrus, and modulated the effective connectivity within the right mirror neuron system (IFG, pSTS, and right inferior parietal lobule). A support vector machine algorithm could classify multivoxel activation patterns in brain regions involved in dynamic facial expression processing in the mentalizing networks (anterior and posterior cingulate cortex). These results indicate that live social interaction modulates the activity and connectivity of the right mirror neuron system and enhances spontaneous mimicry, further facilitating emotional contagion.

A Russian Adaptation of the Emotional Contagion Scale

The aim of the work was to develop and test the Russian version of the Emotional Contagion Scale. A sample of 518 volunteers from the general population filled in this questionnaire. We examined the one-factor model (all the items), the two-factor model (positive/negative), and the five-factor model (love/happiness/fear/anger/sadness). To measure its construct validity, we asked different subsamples to complete questionnaires of empathy and sensation seeking. The coefficients of test-retest reliability, internal consistency, and validity were acceptable. Only the one-factor model showed acceptable properties by all psychometric criteria. We also observed the gender effect, that is women were more contagious, according to the total scale and all subscales.

Building Long-Term Business Sustainability: The Influence of Experiential Marketing on Sales Representatives’ Loyalty to Multi-Level Marketing Systems

Monitoring the satisfaction of sales representatives is a major challenge in business based on multi-level marketing systems (MLM), as a high level of satisfaction could determine the sales representatives’ loyalty and subsequent business growth. The purposes of this study are (i) to measure the sales representatives’ satisfaction with various experiences they face within the MLM system, (ii) to identify the main satisfaction factors that synthetically illustrate the sales representatives’ experiences with the MLM system, and (iii) to determine the influence of satisfaction factors with MLM experiences on the intention to recommend the system to other people interested in joining the business. The research was based on a survey among 412 sales representatives of companies that use an MLM system in various fields of activity. The main factors that summarize the experiences that sales representatives have within the MLM systems have been identified by using an exploratory factor analysis (EFA). Further, the satisfaction with these factors was analyzed in relationship with the intention to recommend the system for the development of their individual business. The research results indicate three major experiences of the sales representatives: (i) experiences within the MLM system, (ii) experiences with customer relationships, and (iii) experiences with the product. The results also show that the higher satisfaction with these factors is, the higher the likelihood to recommend the MLM system. This study provides a contribution to the body of knowledge in using experiential marketing for sustainable business development and provides management insights for companies that use MLM systems.

Emotional Contagion: Research on the Influencing Factors of Social Media Users' Negative Emotional Communication During the COVID-19 Pandemic

During the epidemic, social media platforms were frequently used by users to express and spread negative emotions. Under emotional contagion, individual emotions gradually generalized into group emotions. At the same time, the public could not regulate their emotions and lacked access to release them rationally. This study explores the factors influencing the negative emotions' communication among social media users during the COVID-19 epidemic from the perspective of emotion contagion theory to discover the psychological mechanisms among the public. The questionnaire was tested for reliability and validity and then distributed online on Chinese social media platforms, and the data collected were statistically analyzed. The findings show that there are significant differences in negative emotional communication in social media among different age groups; the seven dimensions of deindividuation, risk perception, group identity, group efficacy, event stimulation, event publicness, and emotion contagion all have significant positive effects on users' negative emotional communication. This study aims to raise public awareness of negative emotions and promote the reconstruction and recovery of public mental health in the epidemic era.

Peer Support and Mental Health of Migrant Domestic Workers: A Scoping Review

The effectiveness of peer support in improving mental health and well-being has been well documented for vulnerable populations. However, how peer support is delivered to migrant domestic workers (MDWs) to support their mental health is still unknown. This scoping review aimed to synthesize evidence on existing peer support services for improving mental health among MDWs. We systematically searched eight electronic databases, as well as grey literature. Two reviewers independently performed title/abstract and full-text screening, and data extraction. Twelve articles were finally included. Two types of peer support were identified from the included studies, i.e., mutual aid and para-professional trained peer support. MDWs mainly seek support from peers through mutual aid for emotional comfort. The study's findings suggest that the para-professional peer support training program was highly feasible and culturally appropriate for MDWs. However, several barriers were identified to affect the successful implementation of peer support, such as concerns about emotion contagion among peers, worries about disclosure of personal information, and lack of support from health professionals. Culture-specific peer support programs should be developed in the future to overcome these barriers to promote more effective mental health practices.

Mass social media-induced illness presenting with Tourette-like behavior

Currently, we are facing a new manifestation of functional neurological disorder presenting with functional Tourette-like behavior (FTB). This study aimed to show characteristics of this phenotype presenting as an outbreak of "mass social media-induced illness" (MSMI) and to explore predisposing factors. Between 5-9/2021, we prospectively investigated 32 patients (mean/median age: 20.1/18 years, range: 11-53 years, n = 16 females) with MSMI-FTB using a neuro-psychiatric examination, a comprehensive semi-structured interview and aspects of the Operationalized Psychodynamic Diagnostic System. In contrast to tics, numbers of complex movements and vocalizations were nine times greater than of "simple" symptoms, and of vocalizations one and a half times greater than of movements. In line with our hypothesis of MSMI, symptoms largely overlapped with those presented by German YouTuber Jan Zimmermann justifying his role as "virtual" index case in current outbreak. Typically, symptoms started abruptly at a mean age of 19 years and deteriorated gradually with no differences between males and females. In all patients, we identified timely-related psychological stressors, unconscious intrapsychic conflicts, and/or structural deficits. Nearly all patients (94%) suffered from further psychiatric symptoms including abnormalities in social behavior (81%), obsessive-compulsive behavior (OCB) (47%), Tourette syndrome (TS) (47%), anxiety (41%), and depression (31%), about half (47%) had experienced bullying, and 75% suffered from coexisting somatic diseases. Our data suggest that pre-existing abnormalities in social behavior and psychiatric symptoms (OCB, anxiety, and depression), but also TS in combination with timely-related psychological stressors, unconscious intrapsychic conflicts, and structural deficits predispose to contagion with MSMI-FTB.
