Exposure to Psychological Aggression at Work and Job Performance: The Mediating Role of Job Attitudes and Personal Health

Despite the growing literature on workplace aggression and the importance of employee performance at work, few studies have examined the relation between workplace aggression and job performance. The purpose of this study was to investigate the relations between psychological aggression at work and two forms of job performance (task performance and contextual performance) and potential mediators of these relations. Based on Conservation of Resources theory and prior research, a model was developed and tested in which overall job attitudes (i.e., job satisfaction and organizational commitment) and overall personal health (i.e., physical and psychological health) fully mediate the relations between exposure to psychological aggression at work and both task performance and contextual performance. Data were obtained from a national probability sample of US workers (N = 2376) and the model was tested using structural equation modelling. The results supported the hypothesized model, demonstrating that exposure to psychological aggression at work negatively predicted both task performance and contextual performance, and that these relations were explained by decrements in job attitudes and health associated with exposure to psychological aggression at work.     

Women, men, VDU work and health: A questionnaire survey of British VDU operators

This paper presents the results of a questionnaire survey of male and female VDU operators distributed through Health & Safety at Work magazine. 3819 questionnaires were analysed using the SPSS computer program. 57% of the sample were female, 68% were under 35 years old and 73% were members of a trade union or staff association. The large number of male respondents meant that it was possible to compare work patterns, types of work and health effects for men and women. It appears that women are engaged in more repetitive and less varied tasks at the VDU and that they work longer hours and for longer periods without a break than men. The most frequently reported health problems were eyestrain, painful or stiff neck and shoulders, fatigue and irritated eyes. The incidence of symptoms was related to hours of work at the VDU. Women were more likely to report health effects than men. This difference remains when hours of work, type of work and hours worked without a break are taken into account. Ergonomically designed equipment such as adjustable chairs, lighting or keyboard did not have an obvious effect on the reporting of symptoms. It appeared that there is a complex interaction between the physical, ergonomic and psychosocial factors associated with new technology. All these factors need to be taken into account in further research into the health problems of VDU operators.     

The relationship between employee motivation and psychological health at work: A chicken-and-egg situation?

Although employee motivation and psychological health at work have been found to be related, it remains unclear whether motivation precedes psychological health or vice versa, and to which extent different manifestations of mental health relate to different forms of motivation at work. Using the self-determination theory and the bidimensional theory of psychological health, this complete panel design study tested the directionality of the relationship between motivation at work and psychological health at work, with a dedicated focus on the specific predictive patterns observed between 4 types of motivation at work and positive and negative indicators of psychological health at work. Eight hundred and five Canadian workers completed questionnaires at 2 times, separated by a 6-month interval. Structural equation modelling analyses indicated that only identified regulation and psychological well-being at work have a fully reciprocal relationship. Only psychological well-being at work was positively associated with the 3 most self-determined types of motivation at work 6 months later, and only identified regulation predicted psychological health at work after 6 months. External regulation was unrelated to all indicators of psychological health at work over time. By integrating 2 theoretical frameworks, this study clarified the relationships between psychological health at work and motivation at work over time.     

Sustained work, fatigue, sleep loss and performance: A review of the issues

The physiological and psychological stressors associated with sustained work, fatigue, and sleep loss affect worker performance. This review describes findings relating to sustained work stresses commonly found in our advancing technological world. Researchers report decrements in sustained performance as a function of fatigue, especially during and following one or more nights of complete sleep loss, or longer periods of reduced or fragmented sleep. Sleep loss appears to result in reduced reaction time, decreased vigilance, perceptual and cognitive distortions, and changes in affect. Sleep loss and workload interact with circadian rhythms in producing their effects. These interactions are a major source of stress in work situations requiring sustained work in continuous operations and have implications for theoretical models of sustained perceptual and cognitive functioning.

Stress, social support, and psychological and physical wellbeing in secondary school teachers

In order to evaluate the relationship between stress and social support, on the one hand, and indices of psychological and physical health, on the other, questionnaires were administered to 120 secondary school teachers. Full data were retrieved from 88 teachers, a response rate of 73%. Bivariate correlational analysis revealed associations between life stress and job stress and a variety of General Health Questionnaire measures of psychological wellbeing. Job stress was also correlated with self-reported short-term sickness absences from work. Social support measures were not. in the main, predictive of psychological health outcome measures. In contrast, neither stress nor social support measures were related to self-reported physical health problems or long-term sickness absences. It would appear that self-reported stress is largely associated with psychological wellbeing, and is not substantially related to indices of physical wellbeing. The former relationship does not appear to be substantially mediated by social support, and may be reflective of a general plaintive set.     

Sickness presenteeism and sickness absence over time: A UK employee perspective

This paper examined the influence of sickness presenteeism (SP), defined here as going to work despite illness, and sickness absenteeism (SA) behaviour on employee psychological well-being, work performance and perceived organisational commitment in a sample of 552 UK workers. Self-report measures were administered on 2 occasions, separated by 1 year, to employees from 4 public sector and 2 private sector organisations. Structural equation modelling was used to evaluate simultaneous influences of SP and SA on outcomes over time. Results suggested that employees reporting SP reported lower work performance in comparison to those reporting no SP, when measured concurrently but not over time. Employees reporting any SP in the previous 3 months showed relatively reduced psychological well-being but there was no significant association over time. Six or more days SP was associated with a reduction in employee perceptions that their organisation was committed to them, concurrently and over time. There were no significant influences of SA on any outcome measure. Our results strengthen previous research and suggest that SP, but not SA, has implications for individual outcomes. The findings have implications for the way organisations manage their sickness absence systems.     

Transformational leadership and optimal functioning at work: On the mediating role of employees' perceived job characteristics and motivation

This study aimed to deepen our understanding of the motivational mechanisms involved in the relationship between transformational leadership (TFL) and employee functioning. Drawing on the TFL literature, the job demands–resources model and self-determination theory, we propose an integrative model that relates TFL to employee psychological health (burnout and psychological distress), attitudes (occupational commitment and turnover intention) and performance (professional efficacy, self-reported individual and objective organizational performance) through two explanatory mechanisms: perceived job characteristics (job demands and resources) and employee motivation (autonomous and controlled). This research was conducted in two occupational settings (nurses and school principals), using a distinct variable operationalization for each. Results of both studies provide support for the hypothesized model, suggesting that TFL relates to optimal job functioning (psychological health, job attitudes and performance) by contributing to favourable perceptions of job characteristics (more resources and less demands) and high-quality work motivation (more autonomous motivation and less controlled motivation) in employees. Theoretical contributions and managerial implications as well as directions for future research are presented.     

Leader-Member Exchange across two hierarchical levels of leadership: concurrent influences on work characteristics and employee psychological health

Leader-Member Exchange (LMX) theory suggests that the quality of the leader–employee relationship is linked to employee psychological health. Leaders who reside at different hierarchical levels have unique roles and spheres of influence and potentially affect employees' work experiences in different ways. Nevertheless, research on the impact of leadership on employee psychological health has largely viewed leaders as a homogeneous group. Expanding on LMX theory, we argue that (1) LMX sourced at the levels of the line manager (LM) and senior management (SM) team will be differentially linked to employee psychological health (assessed as worn-out) and that (2) these relationships will be mediated by perceived work characteristics (reward and recognition, workload management, quality of relationships with colleagues and physical environment). Structural equation modelling on data from 337 manual workers partially supported the hypotheses. Perceptions of the physical environment mediated the relationship between LMX at the LM level and employee psychological health, whereas perceptions of workload management mediated the relationship between LMX at the SM level and psychological health. These findings corroborate arguments that leaders are not a uniform group and as such the effects of LMX on employees will depend on leadership hierarchy. Implications for expanding leadership theory are discussed.

Return to work among employees with mental health problems: Development and validation of a self-efficacy questionnaire

Abstract

Because of the costs to both the organization and the individual, it is important that employees who are sick-listed with mental health problems are facilitated in their return to work (RTW). In order to provide adequate interventions, it is necessary to obtain a better understanding of the RTW process of people with mental health problems. Work-related self-efficacy (SE) might play a key role within this process. This paper describes the development and validation of the return-to-work self-efficacy’ scale (RTW-SE) for employees with mental health problems. Three Dutch samples of sick-listed employees were used to validate the 11-item instrument (N=2214). Based on the factor structure and reliability results, RTW-SE was conceptualized as a unitary construct. The associations with general SE, locus of control, coping, physical workload and mental health problems support the construct validity of this scale. Most importantly, RTW-SE proved to be a robust predictor of actual return to work within three months. The encouraging preliminary psychometric properties of the scale make it a potentially valuable tool in research and in clinical practice and occupational health care settings, both before and after employees have returned to work.     

How extended work availability affects well-being: The mediating roles of psychological detachment and work-family-conflict

Studies have identified availability for work during non-work time as a widespread demand that is related to impaired well-being. Whereas existing research results are based on cross-sectional designs, the present study applied a three-wave longitudinal design to improve interpretations of the direction and causation of the effects of extended work availability. In addition, this study investigated mediating processes such as the reduction of psychological detachment and the increase in work-to-family conflict (WFC). A total of 416 people responded to an online survey at three measurement points, with a time lag of 2 months between each survey, to assess the organisational expectations of being available during one’s off-job time as well as psychological detachment, WFC and emotional exhaustion. The results of structural equation modelling indicated that extended work availability is associated with increases in emotional exhaustion over time. A mediation analysis revealed that WFC and psychological detachment mediated this effect. The results of this study provide strong evidence that extended work availability negatively affects employee well-being over time. Furthermore, this study contributes to an explanation of the mediating process of the detrimental effect. This finding can be used for health-related interventions in cases where extended work availability cannot be completely avoided.     

Research into work stress in Italy: A review

This paper reviews the development of stress research in Italy from the late 1960s onwards. It focuses on 1975 as the year when the first real studies on work stress were published, and interest was kindled in the psychological factors which affect physical health and in the physiological correlates of work stress. Much important work in these aspects of occupational health was started at this time at the Clinic of Work in Milan and at the University of Perugia. By the 1980s, Italian psychologists were also showing considerable interest in work stress, and the more psychological literature had begun to exceed that of a medical and physiological orientation. Despite this progress, stress research in Italy is still in its infancy, and the recognition of stress as an issue for management and trade unions is weak.

Psychosocial safety climate,psychosocial and physical factors in the aetiology of musculoskeletal disorder symptoms and workplace injury compensation claims

Causal agents for workers' compensation claims and physical injury have largely been identified as physical demands. We proposed an integrated theory of physical injury (i.e. musculoskeletal disorder symptoms [MSDs]) and workers' compensation claims, which combined psychosocial and physical mechanisms. A random, population-based sample of 1095 Australian workers completed a telephone interview on two occasions 12 months apart. As expected, the physical mechanism was confirmed; physical demands were related to MSDs, which in turn predicted workers' compensation claims. Further, a novel psychosocial mechanism was confirmed. Psychosocial safety climate (PSC; perceptions about the organisation's climate for psychological health) was a precursor to psychosocial risks (e.g. harassment, violence, bullying and work pressure). In turn, these psychosocial risks were related to emotional exhaustion, MSDs and then workers' compensation claims. Evidence was therefore provided for psychosocial-physical processes in explaining MSDs and workers' compensation for claims for physical injury. Occupational health and safety legislators and policy makers should be aware that, beyond physical demands, factors usually associated with risk for mental stress claims (e.g. harassment, bullying, and violence) may additionally manifest in physical health problems and workers' compensation injury claims. Focusing on modifying the PSC in an organisation, “the cause of the causes”, may be an effective injury prevention and intervention strategy.     

Trainee programme reactions and work performance: the moderating role of intrinsic motivation

This study investigated the moderating role of intrinsic motivation on the relationship between trainee programme reactions and work performance among trainees enrolled in formal trainee programmes. The results from a cross-sectional survey among 114 trainees representing three Norwegian service organizations showed that the relationships between perception of the trainee programme and facets of self-reported work performance were positive only for trainees low in intrinsic motivation. Implications for practice and directions for future research are discussed.     

Training perceptions,engagement, and performance: comparing work engagement and personal role engagement

The purpose of this study was to compare two engagement constructs (work engagement and personal role engagement) with regard to their relationship with training perceptions and work role performance behaviours. It was hypothesised that personal role engagement would show incremental validity above that of work engagement at predicting work role performance behaviours and be a stronger mediator of the relationships between training perceptions and such behaviours. Questionnaire data were gathered from 304 full-time working adults in the UK. As predicted, personal role engagement was found to explain additional variance above that of work engagement for task proficiency, task adaptability, and task proactivity behaviours. Moreover, personal role engagement was a stronger mediator of the relationship between training perceptions and task proficiency as well as between training perceptions and task adaptability. Both work engagement and personal role engagement mediated the relationship between training perceptions and task proactivity to a similar degree. The findings suggest that personal role engagement has better practical utility to the human resource development domain than work engagement and indicates that future research may benefit from adopting the personal role engagement construct.
