The prevalence of childhood bullying and violence victimization and subsequent risk of adult revictimization in the Norwegian population: A cross-sectional study.

Revictimization research has largely ignored bullying victimization, and knowledge of the association between childhood bullying and adulthood revictimization is scarce. Research is also needed to explore whether bullying exposure in combination with childhood violence exacerbates the risk of revictimization. This study sought to address these research gaps in a national probability sample of Norwegian adults (N = 4,299, age range: 18-74 years).

Does job control contribute to differences in physician-certified sickness absence across office concepts? A mediation analysis in a nationally representative sample.

Objectives: Several studies have found higher sickness absence in shared and open workspaces than in private offices, but little is known about why these differences occur. We propose and test job control as a potential mechanism underlying observed differences in the risk of physician-certified sickness absence between private offices and shared and open workspaces.

Methods: We conducted a counterfactual mediation analysis using observational survey data from a nationally representative sample of Norwegian employees merged with prospective data from national registries (N=5512).

Leaders as the targets of workplace bullying - prevalence and outcomes.

Purpose: Bullying of leaders is an underexplored topic in organizational research. To fill this knowledge gap, the aims of this study were to determine the prevalence of bullying of leaders and to examine whether holding a formal leadership position influences the relationships between exposure to bullying and the outcomes job satisfaction and depression.

Methods: Data from two separate surveys were employed: (1) A cross-sectional occupation specific sample comprising 678 Norwegian child welfare social workers; (2) A nationally representative probability sample of 1,608 Norwegian employees with two time-points (6 months' time-lag).

Simulated quick returns in a laboratory context and effects on sleep and pre-sleep arousal between shifts: a crossover controlled trial.

This trial presents a laboratory model investigating the effect of quick returns (QRs, <11 h time off between shifts) on sleep and pre-sleep arousal. Using a crossover design, 63 participants worked a simulated QR condition (8 h time off between consecutive evening- and day shifts) and a day-day (DD) condition (16 h time off between consecutive day shifts). Participants slept at home and sleep was measured using a sleep diary and sleep radar.

Impact of psychosocial work factors on risk of medically certified sick leave due to common mental disorders: a nationwide prospective cohort study of Norwegian home care workers.

Background: The Norwegian home care services experience a high level of sick leave, a large proportion of which is due to common mental disorders. A substantial number of such cases can be attributed to psychosocial factors at work, but more knowledge about occupation-specific risk factors is needed to develop targeted preventive measures to reduce sick leave levels. The aim of this study is to identify the most prominent psychosocial work factors influencing the risk of sick leave spells due to common mental disorders.

Pain, Conflicted Feelings About Work, and Sickness Absence: A Prospective Study of the Effects of Number of Pain Sites and Role Conflicts on Medically Certified Sickness Absence.

We investigated associations between the number of pain sites (NPS) and role conflict with medically certified, pain-related sickness absence (SA) in employees of Norwegian enterprises (N = 5,654). Latent profile analyses identified exposure profiles based on 3 types of role conflict (work-role conflict, work-life conflict, and emotional dissonance). Multinomial logistic regressions estimated effects on absence (short-term absence of less than 56 days, long-term absence of more than 56 days) during 1 year after survey.

Witnessing workplace bullying - protocol for a systematic review and meta-analysis of individual health and well-being outcomes.

Background: Most research on workplace bullying has examined the impact of the mistreatment on those exposed. Although bullying also is assumed to have significant ripple effects on bystanders, the empirical evidence for this line of research is highly fragmented and inconclusive. The overarching aim of this planned systematic review and meta-analysis is therefore to determine whether witnessing bullying of others at the workplace is associated with health problems and lower well-being among the observers.

The contribution of office design to the appraisal of job control: A longitudinal study.

The appraisal of control over work intensity and decisions at the workplace is a well-established determinant of health and well-being among employees. Building on job design theories, the overarching aim of this study was to determine office layout as a predictor of perceived job control. Specifically, we investigated between-group differences in control by contrasting employees in cellular offices with employees in shared/open offices, as well as effects on control among employees transitioning from one office design to another.

Office design, telework from home, and self-certified sickness absence: A cross-sectional study of main and moderating effects in a nationally representative sample.

Objectives: This study aimed to investigate (i) the main effects of office design and access to telework from home (TWFH) on self-certified sickness absence and (ii) the moderating effects of access to TWFH on the relationship between office design and self-certified sickness absence.

Methods: The study used cross-sectional survey data from a nationally representative sample from Norway (N=4329). Research objectives were investigated with negative binomial hurdle models, adjusting for age, gender, education level, leadership responsibility, and time spent on office work.

The impact of follower leadership position on transformational leadership as moderator of the association between work-related ambiguity and job satisfaction.

This two-part study examined if the buffering effect of transformational leadership on the association between work-related ambiguity and job satisfaction is contingent upon whether a follower holds a formal leadership position him/herself. Data from two separate surveys were employed: Study 1: A sample of 845 respondents from Belgium. Study 2: A national probability sample of 1,608 Norwegian employees.

Stress-induced headache in the general working population is moderated by the NRCAM rs2300043 genotype.

Objectives: Earlier findings suggest that social stress such as abusive supervision may promote pain. In the present study we examine the possible moderating role of genetic variability in the gene in this process.

Methods: The data were collected through a national survey drawn from the National Central Employee Register by Statistics Norway.

Mapping of pituitary stress-induced gene regulation connects Nrcam to negative emotions.

Environmental stressors such as repeated social defeat may initiate powerful activation of subconscious parts of the brain. Here, we examine the consequences of such stress (induced by resident-intruder paradigm) on the pituitary gland. In male stressed vs.

Protocol for a systematic review and meta-analysis on the associations between shift work and sickness absence.

Background: Shift work, i.e., non-standard work hours, has been associated with both short- and long-term sickness absence.

Workplace bullying and tiredness at work: A cross-lagged prospective study of causal directions and the moderating effects of a conflict management climate.

Objectives: To prospectively investigate the reciprocal associations between tiredness at work (TAW) and exposure to bullying behaviors and to determine the role of conflict management climate (CMC) as a moderator of these associations.

Methods: A two-wave national probability sample of employees in Sweden (18 months between waves, 921 participated at both waves) measuring TAW, workplace bullying, and CMC. Structural equation modelling was used to test four hypotheses about the longitudinal associations between feeling tired at work and bullying, and CMC as a moderator for the two directions.

The Impact of a Workplace Terrorist Attack on the Psychosocial Work Environment: A Longitudinal Study From Pre- to Post-disaster.

The psychosocial work environment is of great importance for regaining health and productivity after a workplace disaster. Still, there is a lack of knowledge about the impact of a disaster on the psychosocial work environment. The purpose of this study was to examine whether employees' perceptions of role clarity, role conflicts, and predictability in their work situation changed from before to after a workplace terrorist attack.

Patterns of pain complaints and insomnia symptoms are associated with abusive supervision in the Norwegian working population: a latent class analysis.

Objectives: Previous findings suggest that abusive supervision, i.e., subordinates' perceptions of their supervisor's behaviours as hostile (excluding physical aggression), may increase the risk of health complaints.

Associations between workplace bullying and later benefit recipiency among workers with common mental disorders.

Objective: In this study, we examined exposure to workplace bullying as a predictor of registry-based benefit recipiency among workers struggling with work participation due to common mental disorders. Further, we examined if the experience of receiving social support moderated the association between workplace bullying and benefit recipiency.

Design: Secondary analyses of a randomized controlled trial.

Spinal pain in employees exposed to abusive supervision: Evidence of a sex and CRHR1 CTC haplotype interaction.

Previous findings suggest that exposure to social stress in the form of abusive supervision may increase the risk of musculoskeletal disorders. In the present study, we examined the link between abusive supervision, the genotype and spinal pain. The data were collected through a national survey drawn from the National Central Employee Register by Statistics Norway.
