The Present and Future Status of Stress Research

Five research thrusts were identified in current stress research: replications and extensions of ISR's work environment and health model, Type A behavior, psychological burnout, social support, and the work-nonwork interface. However, one or more limitations were noted in stress research methodology which limited the value of much of this work. In addition to addressing these short-comings, future stress researchers are encouraged to employ longitudinal designs and include measures of physiological symptoms. Stress researchers should concentrate on: stress as a process, blue and pink collar workers, work stress of women, sex differences in stress dynamics, and the work, family and societal interface. In addition, bridging the gap between the producers and consumers of stress research findings would achieve betterr informed research and practice. Although occupational stress has become a central variable in OB research, our understanding of stress phenomena remains rather limited. Increases in understanding will continue to come slowly.     

Chronic stress and chronic disease in life and work: Conceptual and methodological issues

This paper argues that the lack of strong prospective evidence linking occupational and social stress to chronic disease stems from the failure of research designs to attend sufficiently to the aetiological chronicity of such diseases. Studies of both supposedly acute stress (life events) and chronic stress in life or work must increasingly be designed to distinguish between stress which is sustained or chronic over a period of yean or even decades, and hence capable of causing a serious chronic disease, and brief or transient stress, which may produce transient or brief psychological or physiological disturbances but cannot generate major chronic disease. Prospective studies are needed which collect measures of both stress and health or disease at multiple points over an extended period of time. Measures of stress should focus more on affect (for example, feelings of pressure and tension) than on cognition (for example feelings of satisfaction). Limited existing evidence is consistent with these ideals.     

Health habits,type A behaviour and job burnout

Abstract

This study examined the effects of health habits and type A behaviour on psychological health outcomes in the face of daily life stress. Measures of the experience of life stress, health habits, type A behaviour, job burnout and psychological distress were collected for 146 employees at the UCLA Medical Centre. Analyses of covariance revealed that health habits contributed significant main effects to psychological distress but not job burnout. Type A behaviour, but not life stress or health habits, directly affected both job burnout and psychological distress. The implications of the research for employee health programmes are discussed.     

Psychosocial safety climate as an antecedent of work characteristics and psychological strain: A multilevel model

Abstract

Psychosocial safety climate (PSC) refers to a specific organizational climate for the psychological health of workers. It is largely determined by management and at low levels is proposed as a latent pathogen for psychosocial risk factors and psychological strain. Using an extended Job Demands-Control-Support framework, we predicted the (24 month) cross-level effects of PSC on psychological strain via work conditions. We used a novel design whereby data from two unrelated samples of nurses working in remote areas were used across time (N=202, Time 1; N=163, Time 2), matched at the work unit level (N= 48). Using hierarchical linear modelling we found that unit PSC assessed by nurses predicted work conditions (workload, control, supervisor support) and psychological strain in different nurses in the same work unit 24 months later. There was evidence that the between-group relationship between unit PSC and psychological strain was mediated via Time 2 work conditions (workload, job control) as well as Time 1 emotional demands. The results support a multilevel work stress model with PSC as a plausible primary cause, or “cause of the causes”, of work-related strain. The study adds to the literature that identifies organizational contextual factors as origins of the work stress process.     

Work satisfaction, health, and stress: A study of Dutch nurses

A study was conducted to compare nurses' work satisfaction and feelings of health and stress in five different nursing departments: a cardiac care unit and a general surgical ward in a general hospital; and an admissions department, a short-stay department, and a long-stay department in a psychiatric hospital. One hundred nurses took part in the study: the instruments used were questionnaires and structured interviews. The main results showed that:

(1) nurses in the cardiac care unit had the most positive satisfaction scores

(2) nurses in the general surgical ward had the most positive scores on the health and stress variables

(3) feelings of dissatisfaction and stress were most prominent in the short-stay department and, to a lesser extent, in the long-stay department.

The findings are interpreted in terms of the different work situations and die implications for hospital management are discussed.

Occupational health psychology

Abstract

An individual's beliefs in relation to stress are likely to affect their perceptions, and hence their work-related actions (such as absenteeism). In this paper, lay representations of work stress were investigated utilising semi-structured interviews with 45 individuals from a range of occupations. The meaning of occupational stress, its antecedents and outcomes, and ways by which it may be managed were examined. Dominant factors were established through the use of thematic content analysis. Similarities and differences were found between lay and professional discourses on work stress. Results indicate that lay representations of occupational stress are multi-faceted. Little consensus was found in how participants interpreted the concept: a diverse range of personal, environmental, and societal factors was highlighted. A different (and arguably more complex) range of definitions of job stress and the manner in which it impacts on individuals was revealed than has been reported in previous studies. The causes of stress at work were perceived as being predominantly organisational, but the impact of stress on the employee was more salient than organisational outcomes. Paradoxically, secondary and tertiary stress management techniques were thought to be more effective than interventions designed to prevent stress at work. Interviewees with line management responsibility were more likely to emphasise individual responsibility for managing stress, most others maintained that the individual and the organisation are equally responsible. The potential value of examining lay representations of job stress to the discipline of Occupational Health Psychology is discussed and suggestions for future research are made.     

Organizational violence and aggression: Development of the three-factor Violence Climate Survey

The aim of this study is to examine the concept of health-specific leadership, differentiate it from sound general leadership and identify whether it has an impact on employee strain, alongside general sound leadership practices. Health-specific leadership is conceptualized as the leader's explicit consideration of and engagement in employee health. The study is based on research in the field of leadership impact on employee strain, health and well-being, extended by recent findings of the importance of domain-specific leadership constructs. As indicated by previous relevant studies, we include psychological climate for health, role ambiguity and job satisfaction as mediating variables. Using structural equation modelling, a sample of 1027 employees of the German tax administration was examined. The results show differential effects for health-specific and general sound leadership. While neither of these two aspects of leadership exhibited a direct association with employee strain, general sound leadership practices were significantly related to lower employee strain through lower levels of role ambiguity, better psychological climate for health and higher job satisfaction. Health-specific leadership was associated with higher levels of psychological climate for health, but also higher role ambiguity.     

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.     

The importance of context specificity in work stress research: A test of the Demand-Control-Support model in academics

The Demand-Control (D-C) (Karasek, 1979) and the Demand-Control-Support (D-C-S) (Johnson & Hall, 1988; Johnson, Hall, & Theorell, 1989; Karasek & Theorell, 1990) models of work stress suggest that jobs with high demands and low control (and low support) are stressful. In line with the support in the literature for context-specificity in occupational stress research (Sparks & Cooper, 1999) and the limited and even contradictory support for interaction effects, the main aim of the present study was to examine how the D-C-S model applied in a well-defined occupational group. Using hierarchical regression analyses, and controlling for negative affect, the D-C-S model accounted for 26%, 6%, and 8% of the variance in job satisfaction, psychological distress and burnout, respectively, among 166 academics in a UK university. No two-way or three-way interactive effects were evident, but additive effects of job demands and control on psychological well-being and of job demands and support on both burnout and job satisfaction were shown, corroborating research showing that high job strain is linked to ill health and job dissatisfaction in this homogenous occupational sample. It is recommended that, in future, research includes more variables that are specific to a particular occupation.

Personality and organizational health: the role of conscientiousness

Organizational health research identifies processes through which the work environment and individual differences combine to influence both individual and organizational outcomes. This study investigated the contribution of conscientiousness to organizational health. Research in the areas of occupational stress, work performance, and organizational climate was used to develop a framework for integrating different elements of organizational health. Within this framework, the work environment was assessed by perceptions of workload and role clarity ; individual well-being was assessed by psychological distress and job satisfaction ; and behaviour important for organizational success was assessed by contextual performance. Conscientiousness was investigated within the framework using self-reports from a sample of 104 Australian employees. Conscientiousness directly influenced contextual performance but did not influence well-being or perceptions of the work environment. Conscientiousness also reduced the impact of role clarity on both psychological distress and job satisfaction. The role of conscientiousness in a comprehensive model of organizational health is discussed.     

Lay representations of workplace stress: What do people really mean when they say they are stressed?

An individual's beliefs in relation to stress are likely to affect their perceptions, and hence their work-related actions (such as absenteeism). In this paper, lay representations of work stress were investigated utilising semi-structured interviews with 45 individuals from a range of occupations. The meaning of occupational stress, its antecedents and outcomes, and ways by which it may be managed were examined. Dominant factors were established through the use of thematic content analysis. Similarities and differences were found between lay and professional discourses on work stress. Results indicate that lay representations of occupational stress are multi-faceted.

Interactive effects of perceived control and job stressors on affective reactions and health outcomes for clerical workers

Karasek's (1979) hypothesis that perceived control interacts with various job stressors in affecting employee satisfaction and health was tested. It was proposed that high levels of perceived stress would only be associated with poor health and negative affect in the presence of low control. One hundred and thirty-six clerical workers at a major US university completed questionnaries containing the measures of interest. The results of regression analyses failed to support the interaction hypothesis. However, measures related to both control and job stressors were found to correlate with satisfaction and health outcomes, as has been found in prior research. Limitations of the self-report and correlational methodology are discussed.     

Coping strategies used by staff following assault by a patient: An exploratory study

This study investigates how people deal with the stress of being the victim of a violent assault at work. A consecutive sample of 24 employees of a psychiatric hospital were questioned over a three-week period following an assault by a patient. The ways in which these staff spontaneously attempted to cope with these assaults was used as a basis for a classification scheme. In addition their psychological difficulties were measured. Despite the restricted sample some interesting associations were found. Ignoring the incident by avoiding thinking about it and taking time away from work or work colleagues was associated with decreases in psychological difficulties over time. Although the causal link is still unclear, further studies using similar analyses may be able to tease this out.     

Psychological and physiological stress responses during repetitive work at an assembly line

The association between psychological and physiological stress responses was examined in 20 male workers at an assembly line. Each worker was studied during a 2 h period on two consecutive days in their normal job and, in order to obtain physiological baseline values, during a corresponding paid 2 h period off the job on the third day. Self-reports of work demands, mood, etc., measurements of catecholamine and cortisol excretion and of systolic and diastolic blood pressure and heart rate were obtained at the end of each of the three 2 h periods. Work induced a significant elevation in almost all psychological and physiological measurements. Levels were consistently lower in workers reporting a 'good' workday compared to those reporting a 'normal' or a 'bad' day. Correlations between self-reports and physiological values showed that catecholamine and cortisol responses, respectively, tended to be associated selectively with different psychological conditions, catecholamine values being associated with feelings of time pressure and pressure by demands, cortisol values with irritation, tenseness and tiredness. The results show that perceived stress at an assembly line is consistently reflected in cardiovascular and neuroendocrine functions of the workers.     

Perceptions of work stress in Australian firefighters

This study surveyed 747 firefighters on their perceptions of work stress. The current emphasis in the fire brigades is on the management of traumatic or critical incident stress, but other work stressors may also be important. The firefighters rated their jobs as more stressful than other occupations, and psychological work stress as highest among a set of potential sources and types of stress. Although many factors were mentioned, the most frequently indicated stressors were associated with exposure to traumatic incidents such as major accidents or the suffering of others. Those who had previous experience with stress were more likely to rate current and future risk of stress as higher. Knowledge of existing organizational approaches to stress management was limited. The firefighters rated individual and informal sessions for dealing with stress as potentially more useful than the formal debriefing sessions now common in many emergency organizatins. Those who had previous experience with stress, however, were more likely to favour a formal organizational approach.     

The effects of fitness training on the physiological stress response

The favourable psychological and physiological profile found in fit sportsmen does not necessarily follow from their exercise behaviour. Alternatively it may depend on endowment and/or self-selection. In that case, participation in regular exercise may not always result in a reduction of susceptibility to stress. The present article reviews several well-controlled laboratory studies that have directly examined the effect of fitness training programmes on the physiological responses to a set of standardized stressors. It was generally expected that fitness training would enhance psychological stress resistance and thus mitigate the physiological response to stress. The results of most studies belie these expectations. Intensive training programmes of up to 8 months do not change stress reactivity, even if initially low fit and high stress-reactive subjects are used. The failure to find a training effect on the intensity of the stress reactions in laboratory studies does not rule out possible psychosocial effects of regular exercise on the frequency and duration of the stress reactions in real-life situations. Furthermore, although the dynamics of the physiological response to stress are not changed, there is a clear downward shift in the overall level of heart rate and blood pressure in stressful situations. Several possible mechanisms are suggested by which these training effects may help us to deal with work stress without suffering health problems.     

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.
