Stress and role satisfaction experienced by employed and nonemployed mothers with young children

The associations between employment status, role choice, social support, stressful events, and mothers' experiences of stress and role satisfaction were investigated. Interviews and questionnaires were used to obtain information from 105 mothers with two-year-old children. Role choice, social support, and stressful events each predicted the amount of stress mothers experienced in their lives, although not all did so independently. Employment status, role choice, and social support predicted role satisfaction.Thanks are extended to Lynn Arner, Susan Goodwyn, and Cindy Litman for their contributions to the project, and to Curt Acredolo and Leanne Friedman for their assistance with statistical analysis and computer programming.Susan B.

Individual and organizational strategies for coping with organizational change

During times of significant change to organizations in strategies and structures, employees can experience high levels of stress as their jobs, areas of responsibility and roles also change. Yet research is curiously silent about how people react to organizational change, especially towards promoting healthy responses to change. As a first step to outlining areas for future research this paper considers a range of individual and organizational strategies that may be effective in reducing employee stress and related problems. Prior to the implementation of these strategies, however, organizations must empower employees to adopt the role of change agent and encourage them to take action to solve the problems that stress them. At the individual level, employees can respond to the stress created by organizational change by using problem- and emotion-focused strategies. Also important in coping with change are the personal resources of employees, including a sense of hardiness, beliefs about having control over their work environment, and the availability of social supports within and outside the organization. Although few organizations fully acknowledge their role in helping employees cope with change, there are a number of initiatives that organizations can pursue. Several strategies are discussed in relation to communication, leadership, job-related tasks and stress management programmes.     

Discrepancies between chronological age and personal age as a reflection of unrelieved worker stress

The general proposition that stress-related variables will be associated with discrepancies between chronological age and perceived personal age of working adults was examined. Responses from a field survey of day, afternoon, and night fixed-shift workers in a large manufacturing organization (n = 1674) were used to explore the relationships between a variety of reported stress-related variables and personal age constructs. Discrepancies between perceived personal age and chronological age were reported by a large proportion of the workers surveyed. Three categories of stress-related variables each accounted for a significant proportion of the variance in discrepancies. As hypothesized, the reported presence of stressors and the frequency/extent of strains (stress-related outcomes) were positively correlated with feeling older than one's chronological age. In addition, the reported presence of support mechanisms for coping with stressors was negatively correlated with feeling older than one's chronological age. The manner in which work and non-work stress may impinge upon personal age perceptions is discussed, and appropriate avenues for future research in this domain are considered.

Back to basics: Re-examination of Demand-Control Theory of occupational stress

The Demand-Control model of occupational stress posits an interaction between job demands and job control predicting psychological strain, but previous research has found such an interaction only rarely or inconsistently. Such research, however, has often failed to measure either demands or strain faithfully to the model's constructs, or has simply failed to test for a statistical interaction. The present study corrected these shortcomings by going back to basics. Using a sample of 115 employees in a manufacturing company, it operationalized the variables more consistently with their original conceptualizations. However, when the hypothesized Demand-Control interaction was then tested, it still failed. Outcomes other than psychological strain (e.g. job dissatisfaction) were related negatively rather than positively to demands. This highlights the difference between psychological strain and dissatisfaction and casts doubt on models positing dissatisfaction as an intervening variable between stressors and strains.     

The social construction of the meaning of acute stressors: A qualitative study of the personal accounts of police officers using a stress counselling service

The police profession is one in which acute stressors are encountered more frequently than in other occupations. Using the personal accounts of 35 police officers attending an in-house stress counselling clinic, the aim of the present study was to provide a qualitative examination of how the institutional context of policing influenced the ways in which acute stressors signified to individual police officers experiencing felt distress. Using the framework of Rational Emotive Behaviour Therapy as an analytical tool, it is argued that beliefs contributing to the experience of felt distress are related to the way in which policing as both an identity and an activity is constructed through the police organizational culture. Not only do these constructions influence the ways in which officers perceive themselves and their environments, but they also operate at the collective level to 'normalize' some emotional responses and to 'pathologize' others which, it is argued, could impact upon the outcomes of interventions such as stress counselling.     

Psychological stress and muscle activity during data entry at visual display units

Abstract

The aim of this study was to evaluate whether psychological stress causes increased muscle activity, especially static muscle activity, in the trapezius muscles of the neck and shoulder. A pilot and a main study were carried out with 10 males and 20 females, respectively. The subjects performed a VDU data entry task under psychologically stressful and non-stressful conditions. Stress reactions were measured by different methods: heart rate and heart rate variability, hormonal excretion, and subjective ratings of mood and body symptoms. The stress condition caused an increase in heart rate. The low-frequency variability increased and the high-frequency variability decreased. Ratings of motivation and relaxation decreased, and subjects felt more activated. Pain and discomfort from the stomach increased. Adrenaline and noradrenaline in urine were unaffected. The majority of the subjects showed moderately increased static and median EMG levels during the stress condition. The interindividual variation in muscular reactions was large. Statistically significant increases were obtained for the myoelectric activity of the left (resting) trapezius muscle when pooling the two groups. It appears that the increase in muscle activity due to this type of mental stress is small, and factors other than ‘attention-related’ load may be more important. The results indicate that some individuals may be more prone to general muscle tension, making them more likely to develop symptoms and musculoskeletal pain.     

Stress and job satisfaction in mammography radiographers

Abstract

Previous research suggests that substantial numbers of health professionals experience undue levels of occupational stress. Little is yet known, however, about a recently established specialized group, namely radiographers who work in the UK National Health Service Breast Screening Programme. All 134 radiographers in the first wave of the programme were sent a postal questionnaire to determine how stressed they felt at work, how satisfied they were with the job, and what were the principal causes of stress and dissatisfaction. A total of 103 were returned, a response rate of 77 %. The results showed that 30 % reported high levels of stress, which is more than in most other professions, and that only 17% described themselves as ‘very satisfied’ with their jobs. The most important predictors of stress were problems of communication (mainly knowing what to tell the client) and conflicts between home and work. The most important predictor of dissatisfaction was role ambiguity. Ways of reducing stress and increasing satisfaction must be found if radiographers are to remain healthy and are to continue to work for the programme.     

A re-analysis of the occupational stress indicator

Abstract

This paper investigates the reliability of the Occupational Stress Indicator (OSI). Data from a sample of university staff, drawn from all areas of an urban university, are used to reassess the apparently low reliabilities of many of the OSI subscales reported by Cooper et al. (1988). In addition, factor analysis results are reported for the first time for the sources of pressure data. The reliability data reported here, while higher reliabilities than originally obtained, remain unacceptably low. A lack of stability in the device as it is currently formulated seems apparent. The paper also presents for the first time a detailed analysis of the sources of pressure scale, indicating a solution different from that proposed by Cooper et al. (1988). Certain areas of the OSI clearly need refinement; the inclusion of locus of control and type A behaviour as personality variables in particular is called into question. Observations regarding the particular strengths and weaknesses of this device, and suggestions for future refinements, are offered.
