Burnout,job stress and violent behaviour among Dutch police officers

Much has been published on burnout in the human services. However, despite the extensive literature on job stress in policing, burnout in police officers has rarely been studied. The present study examined stressors in police work, focusing specifically on the lack of reciprocity that officers experience in relations with civilians, colleagues and the police service. It also investigated the relationship between burnout and the attitudes of officers towards violence, as well as to their own use of violence. Dutch police officers (N = 358) completed a self-report questionnaire. The results showed that: (1) organizational stressors were more prevalent than task-related stressors; (2) compared to other service jobs, police officers report a particular profile on the three scales of the Maslach Burnout Inventory (MBI)?a relatively low level of emotional exhaustion,an average level of depersonalization, and a high level of personal accomplishment; (3) burnout is associated with a lack of reciprocity between investments and outcomes in the relations that officers have with citizens, colleagues and their organization; and (4) burnout is positively related to attitudes towards use of violence and the use of violence during the officers' duty.     

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.     

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.     

Job design and levels of physical and mental strain among Australian prison officers

Abstract

Over the past 15 years much has been made of the moderating influence of job discretion and support in occupations that are perceived to be high in demands. Such an effect seems to be most prevalent when subject populations are large and heterogeneous. One aim of this study was to examine the influence of subjective perceptions of these variables on strain reactions among a group of relatively homogeneous workers such as, in the present study, prison officers (n = 274). A second aim was to extend previous research and examine the joint influence of negative affectivity and perceptions of demands, discretion, and support on mental and physical well-being. It was hypothesized that those high in negative affect would be particularly strained by jobs perceived as being demanding. The hypothesized relationship between job demands, discretion and support were found to be weak and at times inconsistent. Social support, in particular, was found to have both positive and negative consequences for different aspects of well-being. Those high in negative affect were in general found to suffer lower mental well-being. More importantly, the interactive effect of negative affectivity and job demands was found to significantly predict the majority of the dependent variables used in this study. The valences of these relationships were inconsistent and are interpreted in light of Warr's (1987) vitamin model of stress.

There are several conclusions that can be drawn from the present study. Negative affectivity appears to have a truly interactive effect with job components, job demands in particular, to influence a range of variables relating to physical and mental health as well a job-related attitudes. The nature of these effects, however, suggests a dissociation in the ways that different independent variables influence a range of indices of well-being and affect. This result requires further investigation since there are important theoretical implications which will follow if the data are replicable.

In order to examine such complex effects, in addition to the need for more longitudinal studies, it is also important that standardized measures of job components are developed so that levels of stress exposure can be equated and their impact assessed across organizational settings.

Finally, the data reported in this study suggest that some effective stress management may be undertaken by adopting selection strategies which take into consideration individual characteristics. In view of the fact that individual stress management programmes are of unproven benefit (Murphy 1986, 1988) such an approach is recommended especially for those organizations which are highly constrained in the services that must be performed.     

The importance of knowing the affective meaning of job demands revisited

This paper starts with the assumption that when people are asked to describe the level of demands they face at work, it cannot be assumed that those demands are necessarily stressful, even if they are rated as strong or high demands. Thirty demand questions were designed for use with a sample of 2,253 public sector employees in Western Australia. As well as rating frequency of demand the respondents were asked to rate their level of dissatisfaction with the demand. For only 16 of the demands was there a correlation high enough to assume that the demand might be a stressor. Having demonstrated this, the rest of the paper compares different ways of combining the two scores to predict the level of psychological distress as measured by the General Health Questionnaire (GHQ12). The results support the claim in the title, that it is important to know the affective meaning of job demands.     

The stability of job and family involvement: Applying the multi-wave,multi-variable technique to longitudinal data

The main aim of the study was to examine the stability of job and family involvement, applying multi-wave, multi-variable modelling within the framework of LISREL models. The abbreviated job and family involvement scales based on Kanungo's (1979, 1982) motivational model were examined on the basis of 3-year longitudinal data. The study was carried out by means of questionnaires, which were filled in by Finnish employees (n = 109) on three occasions. The results show that both job and family involvement remained relatively stable during the follow-up period. Further, the scales showed reasonable unidimensionality across time. In addition, the item reliability of the scales was found to be adequate. Of the demographic characteristics studied (i.e. gender, age, socioeconomic status, presence of children at home, age of the youngest child) only gender had a significant effect on involvement: men were found to be more involved with their jobs than were women.     

The Job Demand-Control (-Support) Model and psychological well-being: A review of 20 years of empirical research

The Job Demand-Control (JDC) model (Karasek, 1979) and the Job Demand-Control-Support (JDCS) model (Johnson, and Hall, 1988) have dominated research on occupational stress in the last 20 years. This detailed narrative review focuses on the JDC(S) model in relation to psychological well-being. It covers research from 63 samples, published in the period 1979-1997. In the review a distinction is drawn between two different hypotheses prevailing in research on the models. According to the strain hypothesis of the JDC model, employees working in a high-strain job (high demands-low control) experience the lowest well-being. The buffer hypothesis states that control can moderate the negative effects of high demands on well-being. Translating these hypotheses to the expanded JDCS model, the iso-strain hypothesis predicts the most negative outcomes among workers in an iso-strain job (high demands-low control-low social support/isolation), whereas the buffer hypothesis states that social support can moderate the negative impact of high strain on well-being. Although the literature gives considerable support for the strain and iso-strain hypotheses, support for the moderating influence of job control and social support is less consistent. The conceptualization of demands and control is a key factor in discriminating supportive from nonsupportive studies. Only aspects of job control that correspond to the specific demands of a given job moderate the impact of high demands on well-being. Furthermore, certain subpopulations appear to be more vulnerable to high (iso)strain, whereas others benefit more from high control. On the basis of the results of this review, suggestions for future research and theoretical development are formulated.     

Job insecurity and trust: Uncovering a mechanism linking job insecurity to well-being

Job insecurity has well-documented negative effects for individuals as well as organisations. However, the mechanisms by which job insecurity relates to its outcomes have received less research attention. The purpose of this study is to investigate trust in the organisation as a potential mechanism that may explain why job insecurity relates to two well-documented outcomes: decreased job satisfaction and lowered mental health. These hypotheses were tested in a Swedish longitudinal sample that consists of employees (longitudinal n?=?906) from three organisations, using structural equation modelling. Overall, the results showed support for our hypotheses. Our findings reveal an indirect effect of trust on job satisfaction, regardless of whether the previous levels of job satisfaction were controlled for. With regard to mental health, the indirect effect was only evident when previous levels of mental health were not controlled for. The results of this study contribute to our understanding about the intervening factors in the relationship between job insecurity and outcomes. Moreover, the results might be important for human resources departments and managers when there are indications that employees are worrying about the future of their jobs.     

The effects of new dimensions of psychological job demands and job control on active learning and occupational health

Abstract

Recent changes in job content may have led to changes in job demands and control, and earlier operationalizations of the demand concept may be too general (MT). The aim of this paper is to show how new dimensions of psychological job demands are related to two sets of outcome variables, employee health and active learning, and how these relationships are modified or interact with social support and types of job control. The study was carried out as a survey among employees of 13 electric companies in Norway, N=2435. Lisrel was used to assess the fit of the proposed models. Compared to the traditional demands control model, an extended version used in this study increased the explained variance on an average by 4% on various occupational health variables. It was found that various dimensions of demands were differentially related to the outcome variables. Skill discretion uniformly reduced the effect of the demands: for groups low in skill discretion there was a stronger relationship between demands and outcomes than for groups high in skill discretion. The interaction pattern for the remaining control and support variables was however more complicated and warrants further study. The practical implications are that employers should carefully consider the quality of work. Special attention should be given to the quantitative demands of the jobs, since there seems to be few moderators for the relationship between those demands and job stress and subjective health complaints.     

Decision latitude,job demands,and employee well-being

Abstract

Karasek (1979) drew attention to the possibilities that job characteristics may be non-linearly associated with employee well-being, and that they may combine interactively in relation to well-being. This paper examines those issues, and finds that both linear and non-linear components are present in relationships between job features and well-being. However, there is no evidence for a synergistic interaction between decision latitude and job demands. Those job features are differentially predictive of two aspects of well-being: job-related depression-enthusiasm and anxiety-contentment.     

An Enhanced Concave Program Relaxation for Choice Network Revenue Management

The network choice revenue management problem models customers as choosing from an offer set, and the firm decides the best subset to offer at any given moment to maximize expected revenue. The resulting dynamic program for the firm is intractable and approximated by a deterministic linear program called the CDLP which has an exponential number of columns. However, under the choice‐set paradigm when the segment consideration sets overlap, the CDLP is difficult to solve. Column generation has been proposed but finding an entering column has been shown to be NP‐hard. In this study, starting with a concave program formulation called SDCP that is based on segment‐level consideration sets, we add a class of constraints called product constraints (σPC), that project onto subsets of intersections. In addition, we propose a natural direct tightening of the SDCP called , and compare the performance of both methods on the benchmark data sets in the literature. In our computational testing on the data sets, 2PC achieves the CDLP value at a fraction of the CPU time taken by column generation. For a large network our 2PC procedure runs under 70 seconds to come within 0.02% of the CDLP value, while column generation takes around 1 hour; for an even larger network with 68 legs, column generation does not converge even in 10 hours for most of the scenarios while 2PC runs under 9 minutes. Thus we believe our approach is very promising for quickly approximating CDLP when segment consideration sets overlap and the consideration sets themselves are relatively small.     

Resource smoothing: A cost minimization approach

From the available literature, there seems to be no defined approach to resource smoothing exercise except those attempted by Weist (1967, Management Science, 13, B359-B377) and Burgess and Killebrew (1962, Journal of Industrial Engineering, 13, 76-83). The aim of the smoothing exercise is to achieve optimal resource usage by avoiding high peaks and deep valleys in the project resource profile. The general approach has always been to move some activities with floats in the high peak regions to be started at a later date, and as this is done, the valleys will be filled to smooth the resource profile subject of course to time constraint. If this approach is followed as it is, it would be difficult to determine optimality especially when many resources are involved. A cost minimization approach is envisaged in the present study with no limitation on the number of resource inputs. In a situation where the resources are assumed to have the same value, the cost assigned to each of them should be similar. The method follows the general concept but with a difference; cost of the activity in question is considered. The exercise is continued until all the floats are exhausted. The optimum result would then be the one with the minimum cost profile. From examples used for the evaluation, the results obtained are comparable to those of the above two researchers, and some with better results in the majority of cases.     

A conceptual framework for the study of work and mental health

Abstract

The key features which influence mental health both in jobs and unemployment are brought together within a single perspective. Three principal axes of affective well-being are identified as warranting investigation, and it is suggested that nine environmental features are of primary importance. The impact of these features on mental health is viewed as analogous to the influence of vitamins on physical health, with an explicit non-linearity in the relationship. This ‘vitamin model’ is extended to permit examination of individual differences (for example, in terms of baseline values and specific matching characteristics), and empirical evidence is summarized. It is concluded from previous research that job features do not interact synergistically in relation to employee well-being, although this possibility may not yet have been adequately tested. The framework is suggested to be adequately comprehensive, but, as is the case with other models, it requires development in respect of the specific mechanisms operating between environmental features and mental health.     

An economic approach for finding a time-scaled utilization profile for a bending press shop

Abstract

Finding the utilization of a set of machines in a shop floor of a production system by the ratio delay method is a well-known practice in conventional time and motion studies. In this method, the desired reliability of the study is preset and subsequently the data are collected to achieve that reliability. I do not continuously review the reliability in this method while conducting the study nor do I measure the benefit-cost ratio of the undergoing study. In this paper, I describe a method to determine the utilization of a set of production facilities and continuously review the reliability achieved at the end of each survey period. The random observations about the machine status generate a utilization profile of a set of machines on a continuous time scale. Based on the benefit-cost ratio, this method provides us with an information as to when the study has to be stopped in a real time situation. The study is substantiated with a case study and an indication of further research.     

Daily reports of distress: Not for women only

Abstract

A context-dependence paradigm was developed for research into effects of the menstrual cycle in women. This involved the investigation of situational effects on self-reported distress in both men and women. For 35 consecutive days, 25 women and 36 men working in two occupations that varied in degree of situational stress completed Body Awareness Questionnaires (modified menstrual distress questionnaires) and daily subjective stress ratings. After controlling for contraceptive use, age range, and percentage of body fat, the following variables were selected for a multiple regression analysis as predictors of distress: (a) job stress, (b) feminine values, (c) life stress, (d) subjective stress, (e) type of job, (f) sex, (g) job experience, and (h) history of menstrual distress. Women working in the high-stress job (military police) reported significantly more distress than all the other groups. Life stress was identified as the dominant predictor of distress. In a separate analysis of daily distress scores and menstrual cycle phases for all the women, there was no interaction between the type of job and the menstrual cycle phase on reports of distress. A similar analysis of the effects on sex and shift revealed shift effects in distress for men but not women. Sources of variability for both sexes (shift-work rotation and cycle phase) are discussed.     

An Objective Review of the Journal of Organizational Behavior Management

Abstract

This article presents an objective review and analysis of every article published in the Journal of Organizational Behavior Management (JOBM) between 1987 and 1997. The purpose of this review was to replicate and extend the research conducted by Balcazar, Shup-ert, Daniels, Mawhinney, and Hopkins (1989) by providing an objective review and analysis of the second decade of JOBM publications. In doing so, we analyzed several noteworthy trends and patterns occurring within the second decade of the Journal and compared them with the first decade, where applicable. Additionally, we discussed the extent to which the Journal has continued to meet its objectives, and we offered recommendations for future JOBM publications. In general, we found evidence that the Journal has continued to grow in meaningful ways, and we report data that indicate it continues, to some extent, to meet its original objectives. Author affiliation remains largely in academe, although there is evidence that more collaboration is occurring with non-academic authors. The variety of topics addressed by JOBM researchers continues to grow, and the frequency of work simulation studies has increased as well. We also identified areas where future JOBM research could be improved. In particular, more studies should include information on the reliability and social validity of the independent and dependent variables, cost/benefit analyses, and follow-up data.     

Effects of resident-oriented care on job characteristics of nursing caregivers

This study evaluates the effects of the implementation of resident-oriented care on the job characteristics (job autonomy, job demands and social support) of nursing caregivers in three Dutch nursing homes. In a quasi-experimental design, experimental and control groups in both general and psychogeriatric wards were followed for up to 22 months, using a pre-test and two post-tests by means of written questionnaires and semi-structured interviews. The results showed that the intervention appeared to be partly successful. Last post-test regression analyses revealed significant increases in a number of design characteristics of resident-oriented care. Significant increases were noticed on resident assignment, the two variables measuring the nursing process and, in the psychogeriatric experimental group, on resident-oriented tasks (p≤.01). The effects on job characteristics were limited. An indicative increase was shown in contextual job autonomy in the experimental group (p≤.05). The qualitative data derived from the interviews showed that there was still a partly task-oriented division of labour. Further, the delegation of co-ordination tasks to nursing caregivers had not yet been properly achieved. The study concludes with some theoretical and methodological reflections in the light of the findings.     

The Several Meanings of “Positive”

Abstract

Wiegand and Geller propose that the salient role of positive reinforcement in behavior analysis should enable a melding of behavior analysis with developments and concepts that have appeared under the banner of “positive psychology.” However, as is true of many words, the term positive has more than one meaning, and the positive of positive reinforcement is not the same as the positive of “positive psychology.” The latter is parasitic upon the vernacular, as “nice” or “desirable,” whereas the former is analogous to the algebraic “add” as when an action produces the appearance (as contrasted with the removal) of some event. The distinct meanings become clear with recognition that addictive and criminal behavior often are maintained through positive reinforcement, and that negative reinforcement of behavior often is benign and beneficial to the persons involved. In addition, most of the phenomena identified with positive psychology that Wiegand and Geller propose to embrace entail more subtle and complex combinations of behavioral principles than these authors acknowledge. Wiegand and Geller also propose to accommodate vernacular assumptions in ways that separate their approach from its conceptual base; this risks impairing the effectiveness of their work whether or not its marketability would be improved.     

Production systems and supplier selection: a multi-phase process model

Abstract

Purpose: This paper presents a combined multi-phase supplier selection model. The process repeatedly revisits the criteria and sourcing decision as the development process continues. This enables a structured adoption of product and production system innovation from strategic suppliers, where previously the literature purely focuses on product innovation or cost reduction. Design/methodology/approach: The authors adopted an embedded researcher style, inductive, qualitative case study of an industrial supply cluster comprising a focal automotive company and its interaction with three different strategic stamping suppliers. Findings: Our contribution is the multi-phased production and product innovation process. This is an advance from traditional supplier selection and also an extension of ideas of supplier-located product development as it includes production system development, and complements the literature on working with strategic suppliers. Specifically, we explicitly articulate the previously unreported issue of whether a supplier chosen for its innovation capabilities at the start of the new product development process will also be the most appropriate supplier during the production system development phase, when an ability to work collaboratively may be the most important attribute, or in the large-scale production phase when an ability to manufacture at low unit cost may be most important. Originality/value: The paper identifies a multi-phase approach to tendering within a fixed body of strategic suppliers which seeks to identify the optimum technological and process decisions as well as the traditional supplier sourcing choice. These areas have not been combined before and generate a valuable approach for firms to adopt as well as for researchers to extend our understanding of a highly complex process.     

Managing green productivity: Some strategic directions

The twentieth century has been the hallmark for managing total productivity, where the emphasis is towards maximization of outputs commensurate with the consumption of inputs. This is being challenged now to evolve the world class manufacturing strategy requiring a paradigm shift. This shift is towards green productivity, which looks forward to socially appropriate production and consumption aiming at value innovation and resource conservation. This paper is an attempt to outline the concepts and experiential learning about green productivity.
