Psychiatric distress and symptoms of PTSD among victims of bullying at work

Distress and symptoms of Post-Traumatic Stress Disorder (PTSD) were investigated among targets of experienced bullying at work, that is, the exposure to persistent or recurrent oppressive, offensive, abusive behaviour where the aggressor may be a superior or a colleague. The participants in the present study were all recruited from two associations of bullied victims (n=102, response rate=57%). A high level of distress and symptoms of PTSD was revealed in the sample, both according to recommended cut point scores for HSCL-25, PTSS-10 and IES-R, and when comparing the sample with traumatised samples. Three out of four victims reported an HSCL-25 level higher than the recommended threshold for psychiatric disease. Sixty and 63% of the sample reported a high level of IES intrusion and IES avoidance, correspondingly. The level of bullying, operationalised as the frequency of negative acts the individual had been exposed to at work, showed a stronger interconnection with distress and PTSD than a more unspecified, subjective measure of bullying, as well as the time since the bullying took place and the duration of the bullying episode. Those still being pestered reported a higher level of distress and PTSD than victims in which the bullying episodes were terminated more than 1 year ago, but the findings were somewhat mixed. Positive affectivity (PA) and especially negative affectivity (NA) contributed significantly to the explained variance of distress and PTSD in various regression analysis models, but did not interact with measures of bullying. Nor were mediator effects found between bullying, PA/NA and traumatic stress reactions. Implications of the findings are discussed.

The impact of methodological moderators on prevalence rates of workplace bullying. A meta‐analysis

The aim of this study was to investigate how different measurement methods and sampling techniques contribute to the observed variation in prevalence rates of workplace bullying. A total of 102 prevalence estimates of bullying from 86 independent samples (N=130,973) were accumulated and compared by means of meta-analysis. At an average, the statistically independents samples provided an estimate of 14.6%. Yet, the findings show that methodological moderators influence the estimated rates. As for measurement method, a rate of 11.3% was found for studies investigating self-labelled victimization from bullying based on a given definition of the concept, whereas a rate of 14.8% was found for behavioural measure studies, and 18.1% for self-labelling studies without a given definition. A difference of 8.7% points was found between randomly sampled and non-randomly sampled studies. When controlling for geographical differences, the findings show that geographical factors also influence findings on bullying. Hence, findings from different studies on workplace bullying cannot be compared without taking moderator variables into account.

MMPI-2 configurations among victims of bullying at work

Bullying at work, the systematic exposure to psychological violence and harassment in the workplace, places a serious strain on many employees. The aim of this study was to investigate psychological correlates of bullying among former and current victims using the MMPI-2. A total of 85 individuals, recruited among members of two Norwegian associations of bullying victims, participated in the study. Two hypotheses were tested: (1) Bullied victims have an elevated personality profile on the MMPI-2, although different kinds of personality profiles may be distinguished; (2) the personality profiles of the victims are related to the type of behaviour and the intensity of the behaviours experienced by the victim. Both hypotheses were confirmed. The study demonstrated, using cluster analysis, that the sample of bullied victims can be divided into three personality groups (“The seriously affected”, “The disappointed and depressed”, and “The common”.) The elevated 3-2-1 personality profile was most typical. Surprisingly, the victims of the common cluster reported the highest level of exposure to bullying, suggesting a vulnerability factor among the other victims. The scores on the new MMPI-2 Content scales were also analysed. The seriously affected group reported a high level of generalized anxiety, fear of specific incidences, and many health concern worries.

Prevalence of workplace bullying in Norway: Comparisons across time and estimation methods

This study investigates the prevalence of exposure to workplace bullying in a representative sample of 2539 Norwegian employees utilizing different measurement and estimation methods. The prevalence of workplace bullying varied from 2 to 14.3% depending on method of measurement and estimation. Latent class cluster analysis is concluded to give the most reliable estimate (6.8%). Compared to a similar Norwegian study published in 1996, the prevalence of self-reported victimization from bullying is considerably reduced; from 8.6% in the early 1990s to 4.6% in 2005. In the 1996 study, 4.6% labelled themselves as victims of severe bullying, the corresponding number being 2% in 2005.

Perpetrators and targets of bullying at work: role stress and individual differences.

A workplace survey study (N = 2215, response rate 47%) revealed that about 16% of the sample may be categorized as either perpetrators (5.4%), provocative victims (2.1%), or as targets of bullying (8.3%). Targets of bullying, provocative victims, and bullies were compared with those 84% who do not report any involvement with respect to bullying at work, self-esteem, aggressive tendencies, prior experiences of bullying, or experiences of role stress. Perpetrators were found to have a higher level of aggression than did the comparison group and the targets. Provocative victims manifested a low level of self-esteem and social competency combined with a high level of aggressiveness. Targets of bullying revealed low levels of self-esteem and social competency. Targets, provocative victims, and perpetrators reported elevated levels of role stress in the form of unclear or conflicting demands and expectations around work tasks and daily work.

Sense of coherence as a protective mechanism among targets of workplace bullying

The present study investigated sense of coherence (SOC) as a protective factor among targets of workplace bullying. A hypothesis that strong SOC lessens the relationship between exposure to bullying and symptoms of posttraumatic stress was tested in a cross-sectional sample of 221 self-labeled targets of workplace bullying. The findings showed that SOC offers most protective benefits to targets exposed to low levels of bullying, whereas the benefits of SOC diminish as bullying becomes more severe. The results support previous findings that workplace bullying is a traumatic experience for those exposed to it, regardless of the targets available coping resources.

Longitudinal relationships between workplace bullying and psychological distress

OBJECTIVES The aims of this study were to examine reciprocal longitudinal associations between exposure to workplace bullying and symptoms of psychological distress and to investigate how self-labeled victimization from bullying explains the effects of bullying on health. METHODS Logistic regression analysis was employed to examine the longitudinal relationships between workplace bullying and psychological distress in a representative cohort sample of 1775 Norwegian employees. The time-lag between baseline and follow-up was two years. Exposure to bullying behavior was measured with the revised version of the Negative Acts Questionnaire. Perceived victimization from bullying was measured by a single self-labeling question. Psychological distress was measured with the 25-item Hopkins Symptom Checklist. All variables were measured at both baseline and follow-up. RESULTS After adjustment for psychological distress at baseline, exposure to bullying behavior [odds ratio (OR) 1.68, 95% confidence interval (95% CI) 1.07-2.62) was found to predict subsequent psychological distress. This effect of bullying behaviors disappeared when victimization from bullying (OR 2.47, 95% CI 1.17-5.22) was entered into the regression. Both psychological distress (OR 2.49, 95% CI 1.64-3.80) and victimization (OR 2.61, 95% CI 1.42-4.81) at baseline were associated with increased risks of being a target of bullying behaviors at follow-up. Psychological distress (OR 2.51, 95% CI 1.39-4.52) and bullying behaviors (OR 2.95, 95% CI 1.39-4.52) at follow-up were associated with victimization. CONCLUSION The mutual relationship between bullying and psychological distress indicates a vicious circle where bullying and distress reinforce their own negative effects. This highlights the importance of early interventions to stop workplace bullying and provide treatment options to employees with psychological distress.

Predicting proactive behaviour at work: Exploring the role of personality as an antecedent of whistleblowing behaviour

This paper reports on the role of personality as an antecedent of proactive behaviour at work in the form of whistleblowing. In the interest of triangulation, two studies were used, along with two personality measures. The results of Study 1, conducted among 503 municipality employees, show that the NEO Five-Factor Inventory dimensions of extraversion and agreeableness are significantly associated with whistleblowing, with odds ratios of 1.13 and 0.91, respectively. The result from Study 2, conducted among a representative sample of employees, shows that the circumplex of interpersonal problems dimension domineering was significantly associated with whistleblowing, with an odds ratio of 1.66. The results suggest that personality, in the form of high extraversion and dominance and low agreeableness, do play a role as antecedents of whistleblowing.

ORGANIZATIONAL CHANGES: A PRECURSOR OF BULLYING AT WORK?

In the present paper direct as well as indirect relationships between organizational changes and exposure to bullying at work are investigated. Interpersonal conflicts are hypothesized to mediate changes on bullying. Data from a sample of 2408 Norwegian employees confirmed that different organizational changes were moderately associated with task-related bullying at work, and that exposure to more changes increased the likelihood of being bullied. Structural equation modelling supported the assumption that changes were directly related to bullying. However, the hypothesis that changes were mediated on bullying through interpersonal conflicts was not supported. Results indicate that organizational changes and interpersonal conflicts are separate, and mainly independent, precursors of bullying at work.

Workplace bullying as an antecedent to job insecurity and intention to leave: a 6‐month prospective study

Workplace bullying is a severe problem in contemporary working life, affecting up to 15 per cent of employees. Among the detrimental outcomes of bullying, it is even postulated as a major risk factor for exclusion from work. In support of this claim, the current study demonstrates that exposure to bullying behaviour predicts an increase in both levels of job insecurity and intention to leave over a 6-month time lag, among a random sample of North Sea workers (n = 734). The findings suggest that bullied employees are insecure about the permanence and content of their job, and they may be at risk of turnover and exclusion from working life. It is recommended that these outcomes are taken into consideration when incidences of workplace bullying are addressed.
