Short-term effects of social exclusion at work and worries on sleep

Short-term effects of exposure to workplace bullying on objective sleep: an actigraphy diary study

Exposure to bullying behaviours has been associated with a variety of negative health outcomes, such as sleep complaints. However, the current state of the knowledge is limited regarding the association with objective sleep. The present study investigated the short-term effects of workplace bullying on objective sleep patterns using an actigraphy diary approach. Participants (N = 55) wore actigraphy devices for 10 days to measure sleep parameters such as duration, wake-after-sleep onset (WASO), and the number of awakenings. Multilevel analyses showed that exposure to workplace bullying was directly associated with the three parameters of sleep disturbances, with higher levels of bullying linked to poorer sleep outcomes. Anxiety was also found to mediate this relationship. Specifically, anxiety mediated the association between bullying and WASO and sleep duration. The study contributes valuable insights into the detrimental impact of workplace bullying on objective sleep quality, highlighting the importance of addressing psychosocial stressors in the workplace to promote healthy sleep patterns.

Perseverative Cognition as a Mediator Between Perceived Stress and Sleep Disturbance: A Structural Equation Modeling Meta-analysis (meta-SEM)

Background

According to the perseverative cognition (PC) hypothesis, the repetitive chronic activation of the cognitive representations of stressors are associated with a concomitant prolonged and sustained physiological stress response, including sleep disruption.

Purpose

We conducted a systematic review and structural equation modeling meta-analysis (meta-SEM) on PC as mediator of the association between perceived stress and subjective sleep disturbance (i.e., difficulties falling asleep or maintaining sleep).

Methods

PubMed, Scopus, Medline, CINAHL, and PsycInfo were searched up to September 2021. To test mediation, only longitudinal studies assessing the predictor (perceived stress) at T0, the mediator (PC) at T1, and the outcome (sleep disturbance) at T2, were eligible.

Results

Findings on 3,733 individuals (k = 8) showed a significant component effect of perceived stress on PC (β = 0.340, p < .001), which in turn was related to sleep disturbance (β = 0.258, p < .001). The direct effect of stress on sleep disturbance was significant (β = 0.133, p < .001). Lastly, the indirect effect between stress and sleep disturbance via PC supported the mediation hypothesis (β = 0.09, 95% CI 0.078–0.100). The mediation path remained significant (β = 0.03, 95% CI 0.020–0.036) after adjusting for baseline sleep disturbance. Further leave-one-out sensitivity and control analyses confirmed that all direct and indirect effects were not driven by any single study included in the meta-analysis, as well as their robustness when controlling for sex and age, respectively.

Conclusions

Overall, results of this meta-analysis indicate that PC may be one of the mechanisms explaining how perceived stressful experiences lead to subjective sleep disturbance.

Asymmetrical Effects of Sleep and Emotions in Daily Life

Sleep is an important process that can influence and be influenced by daily events and emotions. We examined the bidirectional relationships between sleep, daily events, and emotions with a daily diary method completed by 181 mothers (M _age = 41.91, SD = 5.06). They answered morning and evening questionnaires for 1 week at three different points in time separated by nine months each, 21 days in total. Measures of sleep quality and emotional experiences each morning were assessed, and they reported on their best and worst experience of the day, peak emotional responses to these events, and affect in the evening. Sleep behavior, including total sleep time and sleep efficiency, was objectively quantified using wrist actigraphy. Multilevel modeling analyses showed that longer sleep duration and better subjective quality predicted greater positive emotions and lower negative emotions upon waking, and lower levels of peak perceived stressfulness, but not peak positivity ratings. Daily experiences did not predict sleep duration. Conversely, negative affect in the evening and greater peak perceived stressfulness during the day predicted worse sleep quality that night, whereas positive affect and positive events were not related to sleep. Although correlational, these findings suggest that good sleep can improve waking affect and help mitigate the impact of stressful experiences but does not amplify responses to the positive events of the day. In turn, daily perceived stress reactivity impairs sleep quality. These novel findings show stronger bidirectional relationships between sleep with daily stress, than sleep with daily positivity.

Mittendrin oder nur dabei?

Zusammenfassung. Subjektive Sichtweisen von Arbeitnehmenden mit dauerhaften gesundheitlichen Beeinträchtigungen (dgB) spielen in der quantitativen Forschung zur beruflichen Inklusion bisher eine untergeordnete Rolle. In der vorliegenden Fragebogenstudie wurden daher N = 1006 Betroffene zu ihrem Inklusionserleben, möglichen Konsequenzen, vermittelnden psychologischen Prozessen und der Rolle der Bedürfnisse nach Zugehörigkeit und Authentizität befragt. In Strukturgleichungsmodellierungen mittels Partial-Least-Squares zeigten sich signifikante Zusammenhänge zwischen Inklusionserleben und günstigen Ausprägungen von Indikatoren für Gesundheit, Wohlbefinden und Produktivität, die insbesondere durch eine verminderte affektive Rumination und eine positive Sichtweise auf das Leben mit einer dgB vermittelt wurden. Eine moderierende Rolle der Bedürfnisse nach Zugehörigkeit und Authentizität zeigte sich in den Daten nicht. Die Ergebnisse unterstreichen die Relevanz des Konstrukts Inklusionserleben für Forschung zu beruflicher Teilhabe und die Gestaltung inklusiver Arbeitsumgebungen.

Holding Up a Democratic Facade: How ‘New Work Organizations’ Avoid Resistance and Litigation When Dismissing Their Managers

New work is used as a general term to summarize professional developments in contemporary work style, structure and modus of organizations and society—this means collaborative work and flexible working hours on individual levels, and flat hierarchies and participatory decision-making on organizational levels. Contemporary corporations strive to orient toward the concept of new work to keep up with stakeholder demands, for instance in their branding strategies as an employer. However, studies on organizational practices indicate that alongside explicit values and agendas, organizations tend to slyly exert power to secure their (economic) interests. Constructive dismissal is one such instance where contractually protected employees are made to resign their positions because the work environment is altered to become increasingly unbearable. This research analyzes two case studies to explicate routine dismissal procedures at the managerial level in two internationally operating German corporations. Both corporations explicitly profile as new work environments and are structured according to democratic principles including flat hierarchies, feature institutionalized diversity management including control committees for equal opportunities, and emphasize values such as workplace dignity, employee agency, and equality. The data contain long-term participatory observation collected over a 6-month period from two managers of 5 and 8 years of experience in managerial duties. The content analysis of data reveals characteristics of everyday processes in these organizations especially in terminating managers. The findings are presented as the ‘model of the silent dismissal,’ containing seven types of managerial termination carried out by implicit power and symbolic conventions that circumvent subject participation and litigation in an effortless manner. After exposing the model’s mechanisms, we turn to discuss its meaning for both terminated and surviving subjects against a critical theoretical framework of neoliberalism, democracy, and power.

Career Planning and Self-Efficacy as Predictors of Students’ Career-Related Worry: Direct and Mediated Pathways

The current study seeks to shed light on social-cognitive resources that mitigate master students’ experience of dysfunctional career-related worry before graduation. Based on the career self-management model (CSM; Lent & Brown, 2013 ), we investigate concurrent and time-lagged direct and mediated relationships between career planning, career-related self-efficacy, and career-related worry among a sample of 482 students shortly before graduation. Using data collected at three time points, a negative relationship was found between career planning (T1) and career-related worry (T3) via career-related self-efficacy (T2). Our findings shed light on the role of career planning and career-related self-efficacy as malleable social-cognitive resources that diminish dysfunctional thinking before graduation in sequential order. These findings imply that career planning and career-related self-efficacy are relevant predictors of affective states and can be incorporated into the CSM.

Afro-Venezuelans' Perceived Ethnic Discrimination and Its Association with Levels of Depression

Venezuela is one of the Latin American nations that has traditionally participated in the myth of racial democracy. According to this myth, inasmuch as Venezuela is a racially mixed country, racism is largely absent. That has made virtually invisible the plight of Afro-Venezuelans, who continue to suffer discrimination. In the present study, 402 Afro-Venezuelans were surveyed regarding their perceived discrimination and their levels of depression. Results came out showing that, compared to white Venezuelans, Afro-Venezuelans are more likely to suffer both perceived discrimination and depression. Likewise, it was also found that among Afro-Venezuelans, perceived discrimination has a statistically significant correlation with depression. However, one particular marker of depression (suicidal ideation) does not have correlation with any dimension of perceived discrimination.

Why Victimized Employees Become Less Engaged at Work: An Integrated Model for Testing the Mediating Role of Sleep Quality

Recent studies have shown that workplace victimization is negatively related to work engagement. The explanations for the underlying mechanisms, however, are still in a nascent stage. Drawing on the limited resource theory of self-regulation and research on workplace aggression and sleep, we develop and test an integrated model, which explains that victimized employees may have impaired sleep quality and thus have less energy and be less likely to be engaged in their work. The results of logistic regression and structural equation modeling analyses of large-scale survey data collected from 90,272 employees across the years 2010, 2011, 2014, and 2017, indicate that workplace victimization is negatively related to sleep quality and subsequent workplace engagement, even controlling for alternative explanations-job insecurity and basic psychological needs for competence, autonomy, and relatedness. Our findings advance our knowledge on the detrimental consequences of workplace victimization and suggest that, while unmet basic psychological needs matter, impaired sleep quality is one reason why victimized employees find it difficult to engage at work.

Qualitative Study on the Toxic Triangle Integration of Leadership Ostracism

Leadership ostracism widely exists in all types of organizations, yet specific study regarding this trend is limited. With this study, we explore the influencing mechanisms of leadership ostracism through case interview based on literature analysis and grounded theory. Results show that leadership ostracism is the integration of a triadic interaction process between subordinate performance, leadership characteristics, and organizational environment. Based on Padilla's destructive leadership toxic triangle model, we constructed a toxic triangle model of leadership ostracism. Through comparison, we found that these two triad models overlap in the areas of narcissism and power consciousness of supervisors, the self-concept of subordinates, and the management system of situational factors, indicating that leadership ostracism is itself a type of destructive leadership. In addition, the uniqueness, and differences in leadership ostracism are reflected in the model, including stereotypes, and results orientation of supervisors, political skills, job performance, and cognitive style of subordinates, the power distance, Chaxu climate, and organizational politics of the situational elements. Theoretical and practical implications are discussed in the research field that provides prospects for future orientation.

Associations between exposure to workplace bullying and insomnia: a cross-lagged prospective study of causal directions

Objective

Workplace bullying has been established as a significant correlate of sleep problems. However, little is known regarding the causal direction between bullying and sleep. The aim of this study was to examine temporal relationships between bullying and symptoms of insomnia.

Methods

Reciprocal and prospective associations between exposure to workplace bullying and symptoms of insomnia were investigated in a national probability sample comprising 1149 Norwegian employees. Data stemmed from a two-wave full panel survey study with a 6-month time interval between the baseline and follow-up assessments. Models with stabilities, forward-, reverse-, and reciprocal associations were tested and compared using Structural Equation Modelling. Analyses were adjusted for age, gender, and the stability in the outcome variables over time. Workplace bullying was assessed with the nine-item Short Negative Acts Questionnaire. Insomnia was assessed with a previously validated three item scale reflecting problems with sleep onset, sleep maintenance, and early morning awakening.

Results

The forward association model, which showed that exposure to workplace bullying prospectively increased levels of insomnia (b = 0.08; p < 0.001), had best fit with the data [CFI = 0.94; TLI = 0.93; RMSEA = 0.049 (0.046–0.052)]. The reverse association model where insomnia influences risk of being subjected to bullying was not supported.

Conclusion

Workplace bullying is a risk factor for later insomnia. There is a need for further studies on moderating and mediating variables that can explain how and when bullying influence sleep.

Sleep and social relationships in healthy populations: A systematic review

Over the past decade, research linking sleep and social relationships has burgeoned. Researchers across the globe are trying to understand whether the quality and quantity of our social relationships matter for sleep, and vice versa. We conducted a systematic review of the literature, identifying over 200 relevant articles examining sleep and social relationships in healthy populations. Here, we summarize our findings by reviewing 1) links between sleep and broad social ties across the lifespan, and 2) links between sleep and specific social relationships identified in the literature search, including romantic relationships, family relationships, and work relationships. Taken together, the literature provides evidence that the quality and presence of social relationships, especially our closest relationships, play a role in how we sleep. Likewise, sleep appears to influence our social bonds. However, the majority of work is correlational, limiting conclusions about the directionality of these effects. We conclude by synthesizing the findings, considering the limitations of the present literature, and identifying key future directions for this emerging area of research.

The associations between loneliness, social exclusion and pain in the general population: A N=502,528 cross-sectional UK Biobank study

Chronic pain presents a huge burden for individuals and society and evidence suggests intrinsic links with loneliness, social exclusion and sleep. Research examining how these factors interact is warranted. We aimed to explore the relationships between social exclusion, loneliness, acute and chronic pain, and the influence of poor sleep, in the general UK population. A cross-sectional analysis of UKBiobank participants with baseline data for acute and chronic pain, loneliness and sleep. Principal components analysis (PCA) used data relating to social isolation and deprivation to establish a composite measure of social exclusion. Binary logistic regression analyses were performed. 502,528 UKBiobank participants (mean age = 56.6years, 54.4%female, 94.6%white) were included in the analysis. PCA suggested three social exclusion factors "social participation", "individual deprivation" and "area deprivation". Loneliness significantly predicted acute (OR:1.887; 95%CI1.857-1.917) and chronic pain (OR:1.843; 95%CI1.816-1.870). Each social exclusion factor alone and in combination significantly predicted pain with largest effects for individuals scoring high on all social exclusion factors, for acute (OR:2.087; 95%CI2.026-2.150) and chronic (OR:2.314; 95%CI2.249-2.380) pain. Coefficients remained statistically significant when models were adjusted for demographics and sleep. Social exclusion (as a multifaceted construct) and loneliness are associated with an increased prevalence of acute and chronic pain. Poor sleep has a potential mediating effect on these associations. Exploration of the incidence of pain in loneliness and social exclusion in the general population is warranted. From a public health perspective these findings could be used to design social interventions to prevent or manage pain and mitigate social exclusion.

Cognitive arousal mediates the relationship between perceived ostracism and sleep quality but it is not moderated by experiential avoidance

Previous research suggests that longer-term perceived ostracism is related to poor sleep quality. In this study, we investigated the mediating effect of cognitive arousal on the perceived ostracism-sleep quality relationship. We also investigated whether experiential avoidance was a moderator of the cognitive arousal-sleep quality relationship. Participants (N = 251) were recruited through online research portals to take part in an online survey. A path analysis was used to test a moderated mediation effect between variables. It was found that cognitive arousal mediated the perceived ostracism-sleep quality relationship; however, experiential avoidance was not a significant moderator. These findings suggest that further research needs to be conducted to elucidate the mechanism of experiential avoidance to account for when it may impact sleep quality. Moreover, treatment interventions targeted at reducing cognitive arousal (e.g., cognitive behavioural therapy) prior to sleep are likely to bear some fruit.

Failing Is Derailing: The Underperformance as a Stressor Model

Job performance and job stress are widely studied phenomena in occupational research. However, most literatures on the relationship between work stress and job performance conceptualize job stress as an antecedent of performance, in line with the stress-performance framework, and do not examine what happens to the well-being of the employees after the performance was appraised as poor. In the current theoretical paper, I argue that task underperformance is a source of stress (i.e., stressor) for the employee and, as such, can affect a wide range of employee outcomes. Task underperformance is conceptualized as comprised of two main types: acute/episodic underperformance, such as a mistake or an accident (e.g., medical error and service failure), and chronic task underperformance, such as not achieving the expected work products over time, with an interplay between these types. The source of the appraisal (objective, supervisor-rated, and self-rated underperformance) is also considered. Several disjoint literatures are then integrated in order to explain how underperformance is expected to result in subsequent decrements to employee well-being. At the chronic underperformance level, the following literatures are included: self-efficacy, negative effects of performance feedback, and stress experienced when the basic need for competency is frustrated or when underperformance presents a threat to the self-image. At the acute/episodic level, affective and cognitive outcomes are explored, and examples are drawn from several industries including service failures and medical errors. The interplay between the two types of underperformance, acute/episodic and chronic, is discussed, and then relevant moderators are offered. One notable moderator is the occupation-level consequences of error, which likely affects most if not all outcomes. Finally, the discussion includes potential theoretical and practical implications for this conceptualization, as well as some methodological considerations for future research in this area.

Put you down versus tune you out: Further understanding active and passive e-mail incivility

Although e-mail incivility is becoming a growing concern in the workplace, it remains an understudied topic. Scholars have paid inadequate attention to its dimensionality (i.e., active and passive e-mail incivility) and its impact on well-being outcomes, thus precluding a more comprehensive understanding of its implications in the workplace. To address these gaps, we conducted two studies to investigate the nature and outcomes of e-mail incivility. In Study 1, we surveyed a sample of working employees about their e-mail incivility experiences at work and collected their appraisals of a discrete e-mail incivility event. Confirmatory factor analysis results provide support for the empirical distinction between the 2 dimensions. Findings from event-level appraisals highlight that active e-mail incivility leads to a greater level of emotionality appraisal, whereas passive e-mail incivility is viewed as more ambiguous. In Study 2, we conducted a diary study to examine the spillover effects of e-mail incivility on well-being. Multilevel modeling results indicate that passive e-mail incivility is positively associated with insomnia, which then leads to heightened negative affect at the beginning of the workday. Overall, this research clarifies the nature of e-mail incivility dimensions, highlights their detrimental effects on employee well-being, and identifies important implications for occupational health scholars and practitioners.

Sleep and Organizational Behavior: Implications for Workplace Productivity and Safety

The interaction between sleep and work-related behaviors influence many aspects of employee performance, safety, and health as well as organizational-level success. Although it is well established that quantity and quality of sleep can affect different types of task performance and personal health, the interactions between sleep habits and organizational behaviors have received much less attention. It is important to examine how sleep habits and workplace behaviors relate and the role of the underlying circadian rhythm on the potential impact of sleep and sleepiness in the workplace. Developing a deeper understanding of how sleep habits and sleepiness impact workers and the organization can help provide the necessary background for human resource management to develop more progressive support networks for employees that benefit both the worker and the organization. Human resources and employees should emphasize the impact of good sleep and sleep habits on organizational and individual productivity and safety.

Work and sleep quality in railway employees: an actigraphy study

This actigraphy study tests whether daily work stressors (time pressure, social stressors), work resources (control, social support) and mental detachment from work predict sleep quality, when controlling for demands and control after work. Fifty-two railway employees participated during five consecutive workdays by completing diary questionnaires and wearing an actigraphy device. The results confirmed that social stressors from supervisors predicted more frequent sleep fragmentation and lower sleep efficiency the following night. Higher levels of daily time control at work predicted shorter sleep-onset latency and better self-reported sleep quality. Leisure time control as a covariate turned out to be a private resource, followed by fewer awakenings the following night. Detachment after work related negatively to social stressors and time pressure at work but was unrelated to indicators of sleep quality; detachment after work neither mediated nor moderated the relationship between social stressors from supervisors and sleep quality. Work redesign to increase time control and reduce social stressors is recommended to preserve daily recovery in railway employees. Practitioner summary: Sleep is important to renew health- and safety-related resources in railway employees. This diary and actigraphy study shows that higher daily work stressors were antecedents of lower sleep quality the following night, while more time control was followed by better sleep quality. Work redesign could promote health and safety by improving sleep quality.

A moderated mediation model of workplace ostracism and task performance

Purpose

Ostracism within organizations may pose communication challenges and reduce opportunities for interactions, potentially affecting coworker knowledge sharing and subsequent performance outcomes. Drawing on conservation of resources theory, the purpose of this paper is to examine whether knowledge sharing mediates the association between workplace ostracism and employees’ task performance, and whether the mediating effect is moderated by task interdependence.

Design/methodology/approach

Matched data were collected from a two-wave survey among 210 employees and their direct supervisors who work in two Chinese enterprises.

Findings

Results indicate that workplace ostracism is negatively associated with task performance and that knowledge sharing mediates this relation. Further, task interdependence exacerbated the main effect of workplace ostracism and the indirect effect of knowledge sharing.

Originality/value

This paper offers an alternative perspective (i.e. pragmatic impacts of workplace ostracism) to understand how workplace ostracism undermines employees’ task performance. Moreover, the findings emphasize that contextual factors may strengthen the detrimental effects of workplace ostracism in the practical domain.

Stress as Offense to Self: a Promising Approach Comes of Age

Stress is related to goals being thwarted. Arguably, protecting one’s self, both in terms of personal self-esteem and in terms of social self-esteem, is among the most prominent goals people pursue. Although this line of thought is hardly disputed, it does not play the prominent role in occupational health psychology that we think it deserves. Stress-as-Offense-to-Self theory focuses on threats and boosts to the self as important aspects of stressful, and resourceful, experiences at work. Within this framework we have developed the new concepts of illegitimate tasks and illegitimate stressors; we have investigated appreciation as a construct in its own right, rather than as part of larger constructs such as social support; and we propose that the threshold for noticing implications for the self in one’s surroundings typically is low, implying that even subtle negative cues are likely to be appraised as offending, as exemplified by the concept of subtly offending feedback. Updating the first publication of the SOS concept, the current paper presents its theoretical rationale as well as research conducted so far. Research has covered a variety of phenomena, but the emphasis has been (a) on illegitimate tasks, which now can be considered as an established stressor, and (b) on appreciation, showing its importance in general and as a core element of social support. Furthermore, we discuss implications for further research as well as practical implications of an approach that is organized around threats and boosts to the self, thus complementing approaches that are organized around specific conditions or behaviors.

Quality of leadership and presenteeism in health professions education and research: a test of a recovery-based process model with cognitive irritation and impaired sleep as mediators

Presenteeism (PRES) includes working while feeling ill and constrained in performance. Compared with absence from work, PRES generates significantly higher cost estimates. Health problems and PRES are related to leadership quality. Hence, research on corporate health management needs to explore why leadership problems (LP) correspond to more frequent PRES.This study tests recovery after work as an underlying process with cognitive irritation (COGIRR) and sleep problems (SP) as simultaneous mediators and explores three mediation pathways (path one: LP→COGIRR→PRES; path two: LP→SP→PRES; and path three: LP→COGIRR→SP→PRES). Out of 293 employees of a university's school of health professions in German-speaking Switzerland, 211 completed a questionnaire. LP and PRES were found to be positively related (r(211) = .22, p < .01). The tests of mediation yielded no significant results for path one and two, but the third mediation path LP→COGIRR→SP→PRES was positive and differed significantly from zero (B = 0.83, CI95 = 0.33 to 1.69). According to our results, a recovery-based mediation model fits the empirical self-report data best. These results suggest that occupational health interventions should improve leadership quality to promote recovery after work in order to increase health and productivity by reduced PRES.

The Relationship Between Workplace Ostracism and Sleep Quality: A Mediated Moderation Model

Extant research suggests that workplace ostracism has a detrimental impact on the outcomes of employees. However, very little is known about the impact of workplace ostracism on sleep quality. Therefore, this study aimed to address this gap in the literature. By employing the extended stressor-detachment model, we investigated the mediating role of psychological detachment and the moderating role of coping humor. We used a self-report questionnaire and a time-lagged research design to assess employees' workplace ostracism, coping humor, psychological detachment, and sleep quality. A total of 403 valid questionnaires were obtained from participants in full-time employment in China. As predicted, the results showed that workplace ostracism is negatively associated with psychological detachment, which in turn, impairs sleep quality. We further found that high levels of coping humor buffer the negative effect of workplace ostracism on psychological detachment and sleep quality. In addition, the moderation effect of coping humor on the relationship between workplace ostracism and sleep quality is mediated by psychological detachment. Finally, based upon the results, we discuss the theoretical implications, provide practical proposals for managers and policymakers, and make suggestions for the direction of further research.

High-Frequency Heart Rate Variability Reactivity and Trait Worry Interact to Predict the Development of Sleep Disturbances in Response to a Naturalistic Stressor

BACKGROUND

High-frequency heart rate variability (HF-HRV) reactivity was proposed as a vulnerability factor for stress-induced sleep disturbances. Its effect may be amplified among individuals with high trait worry or sleep reactivity.

PURPOSE

This study evaluated whether HF-HRV reactivity to a worry induction, sleep reactivity, and trait worry predict increases in sleep disturbances in response to academic stress, a naturalistic stressor.

METHOD

A longitudinal study following 102 undergraduate students during an academic semester with well-defined periods of lower and higher academic stress was conducted. HF-HRV reactivity to a worry induction, trait worry using the Penn State Worry Questionnaire, and sleep reactivity using the Ford Insomnia Stress Reactivity Test were measured during the low stress period. Sleep disturbances using the Pittsburgh Sleep Quality Index were assessed twice during the lower stress period and three times during the higher stress period.

RESULTS

Greater reductions in HF-HRV in response to the worry induction predicted increases in sleep disturbances from the lower to the higher academic stress period. Trait worry moderated this association: individuals with both higher trait worry and greater HF-HRV reactivity to worry had larger increases in stress-related sleep disturbances over time, compared to participants with lower trait worry and HF-HRV reactivity. A similar, but marginally significant effect was found for sleep reactivity.

CONCLUSION

This study supports the role of HF-HRV reactivity as a vulnerability factor for stress-induced sleep disturbances. The combination of high trait worry and high HF-HRV reactivity to worry might identify a subgroup of individuals most vulnerable to stress-related sleep disturbances.

The Vicious Circle of Working Hours, Sleep, and Recovery in Expert Work

This study aimed to investigate working hours, sleep quality and alertness, and recovery and detachment in expert work using a mobile app. The study sample comprised members of The Finnish Business School Graduates and employees of an information technology (IT) company. The final study sample included 154 employees with at least four days of mobile app data. For statistical analyses of the survey and mobile app data (cross-sectional setting), we used logistic regression, and for the day-to-day data, we used multi-level logistic regression to calculate the odds ratios (OR), and a general equation estimates model for regression coefficients with 95% confidence intervals (CI). The results showed that moderate to fair sleep quality or alertness at awakening were associated with longer working hours the following day (OR 1.07–1.14, 95% CI 1.01–1.22). Recovery and detachment during the preceding day were associated with longer working hours. These associations were the same in the opposite direction. To conclude, the day-to-day ratings of sleep quality and alertness at awakening, and recovery and detachment from work during leisure time were associated with increased working hours the following day. In addition, longer working hours the preceding day were associated with worse ratings of sleep quality, alertness, recovery, and detachment.

Impaired sleep predicts onset of low back pain and burnout symptoms: evidence from a three-wave study

In a three-wave questionnaire study of 405 working participants, who were initially free of low back pain (LBP) and emotional exhaustion, sleep problems were evaluated as a potential risk factor for the development of LBP and burnout up to three years later. Prospective risk paths were compared between the sexes and between two age-groups (18 to 45 years and older than 45 years). A longitudinal structural equation model showed a good fit with empirical data (RMSEA = .04, SRMR = .06, CFI = .97). Prospective risk paths between the latent constructs showed sleep problems to significantly predict self-reported LBP (β = .15, p = .011) and burnout (β = .24, p < .001) two years later. Sleep problems also predicted the occurrence of burnout three years later (β = .18, p = .002). Sleep-related risk of burnout after two years was greater in older than younger participants (β_older = .42 vs. β_younger = .13, p < .001). Sleep problems seem to precede LBP and burnout in working individuals. Health promotion initiatives should use sleep quality as an important early risk indicator, and interventions should focus on promoting better quality sleep, in an attempt to reduce the incidence of LBP and burnout.

The impact of social exclusion on anticipatory attentional processing

The importance of understanding how we anticipate and prepare for social rejection is underscored by the mental and physical toll of continual social vigilance. In this study, we investigate the impact of social rejection on anticipatory attentional processes using the well-known Cyberball task, a paradigm in which participants engage in a game of catch with virtual avatars who after an initial period of fair-play (inclusion condition) then exclude the participant from the game (exclusion condition). The degree of anticipatory attention allocated by subjects towards the avatars was assessed by measuring P3b responses towards the avatars' preparatory actions (i.e. the phase preceding their exclusionary actions) using high density EEG. The results of the study show that relative to the inclusion, participants exhibit elevated levels of anticipatory attentional allocation towards the avatars during the exclusion block. This shift was however significantly moderated by participants' self-reported cognitive regulation tendencies. Participants with higher levels of self-reported cognitive reappraisal tendencies showed larger anticipatory P3b increases from the inclusion to exclusion block relative to participants with reduced levels of reappraisal tendencies. These results highlight the impact of social exclusion on anticipatory neural processing and the moderating role of cognitive reappraisal on these effects.

Comparing and Contrasting Workplace Ostracism and Incivility

Despite their shared characteristics, the literatures on workplace ostracism and incivility have evolved in different directions. In this review, we discuss the similarities and differences in the conceptualizations of the two constructs and trace the different measures, histories, theories, and topics covered in the two literatures. Although small, we also review the subset of studies that have directly contrasted the effects of ostracism and incivility within the same study. Subsequently, we outline future research areas for both literatures, with a particular focus on research areas that may produce results that help further differentiate the two constructs.

Why won't they sit with me? An exploratory investigation of stereotyped cues, social exclusion, and the P3b

The importance of understanding how we anticipate and prepare for being socially excluded is underscored by the numerous adverse mental and physical consequences of social rejection. In this study, we adapted a social exclusion paradigm, the Lunchroom task, to investigate the use of social context cues in the formation of social outcome expectations as indexed by the P3b, an ERP component associated with attention orientation and context updating. In this task, Black and White participants were presented with either neutral or stereotyped cues prior to being exposed to simulated inclusion versus exclusion outcome scenarios. Black participants showed evidence of (1) a significantly reduced P3b response to exclusions preceded by stereotyped cues relative to neutral cue-related exclusions and (2) a marginally significant increase in the P3b response to inclusions relative to exclusions when both were preceded by stereotyped cues. Both of these findings suggest a key role for the use of social cues in the formation of outcome expectations. In line with our hypothesis that the random intermixing of inclusion and exclusion outcomes would prevent formation of outcome expectations when coupled with the absence of self-relevant cues, no overall P3b modulations were observed among a comparison group of White participants.

Comparing Subjective With Objective Sleep Parameters Via Multisensory Actigraphy in German Physical Education Students

This study compared subjective with objective sleep parameters among 72 physical education students. Furthermore, the study determined whether 24-hr recording differs from nighttime recording only. Participants wore the SenseWear Armband™ for three consecutive nights and kept a sleep log. Agreement rates ranged from moderate to low for sleep onset latency (ICC = 0.39 to 0.70) and wake after sleep onset (ICC = 0.22 to 0.59), while time in bed (ICC = 0.93 to 0.95) and total sleep time (ICC = 0.90 to 0.92) revealed strong agreement during this period. Comparing deviations between 24-hr wearing time (n = 24) and night-only application (n = 20) revealed no statistical difference (p > 0.05). As athletic populations have yet to be investigated for these purposes, this study provides useful indicators and practical implications for future studies.

Workflow interruptions, social stressors from supervisor(s) and attention failure in surgery personnel

Workflow interruptions and social stressors among surgery personnel may cause attention failure at work that may increase rumination about work issues during leisure time. The test of these assumptions should contribute to the understanding of exhaustion in surgery personnel and patient safety. Workflow interruptions and supervisor-related social stressors were tested to predict attention failure that predicts work-related rumination during leisure time. One hundred ninety-four theatre nurses, anaesthetists and surgeons from a Swiss University hospital participated in a cross-sectional survey. The participation rate was 58%. Structural equation modelling confirmed both indirect paths from workflow interruptions and social stressors via attention failure on rumination (both p<0.05). An alternative model, assuming the reversed indirect causation-from attention failure via workflow interruptions and social stressors on rumination-could not be empirically supported. Workflow interruptions and social stressors at work are likely to trigger attention failure in surgery personnel. Work redesign and team intervention could help surgery personnel to maintain a high level of quality and patient safety and detach from work related issues to recover during leisure time.
