Study of the validity of a job-exposure matrix for psychosocial work factors: results from the national French SUMER survey

Objective  To construct and evaluate the validity of a job-exposure matrix (JEM) for psychosocial work factors defined by Karasek’s model using national representative data of the French working population. Methods  National sample of 24,486 men and women who filled in the Job Content Questionnaire (JCQ) by Karasek measuring the scores of psychological demands, decision latitude, and social support (individual scores) in 2003 (response rate 96.5%). Median values of the three scores in the total sample of men and women were used to define high demands, low latitude, and low support (individual binary exposures). Job title was defined by both occupation and economic activity that were coded using detailed national classifications (PCS and NAF/NACE). Two JEM measures were calculated from the individual scores of demands, latitude and support for each job title: JEM scores (mean of the individual score) and JEM binary exposures (JEM score dichotomized at the median). Results  The analysis of the variance of the individual scores of demands, latitude, and support explained by occupations and economic activities, of the correlation and agreement between individual measures and JEM measures, and of the sensitivity and specificity of JEM exposures, as well as the study of the associations with self-reported health showed a low validity of JEM measures for psychological demands and social support, and a relatively higher validity for decision latitude compared with individual measures. Conclusion  Job-exposure matrix measure for decision latitude might be used as a complementary exposure assessment. Further research is needed to evaluate the validity of JEM for psychosocial work factors.     

The contribution of occupational factors to social inequalities in health: findings from the national French SUMER survey

Social inequalities in health have long been demonstrated, but the understanding of these inequalities remains unclear. Work and its related occupational factors may contribute to these inequalities. The objective of this study was to study the contribution of work factors using an integrated approach (including all types of exposures) to social inequalities in three health outcomes: poor self-reported health, long sickness absence, and work injury. Respondents were 14,241 men and 10,245 women drawn from a survey of the national French working population (response rate: 96.5%). Work factors included job characteristics, and occupational exposures of the physical, ergonomic, biological, chemical, and psychosocial work environment. All work factors were measured through expert evaluation by occupational physicians, except psychosocial work factors, which were self-reported. Strong social gradients were found for all work factors, except for psychological demands, workplace bullying, and aggression from the public. Marked social gradients were also observed for the health outcomes studied, blue collar workers being more likely to report poor self-reported health, long sickness absence, and work injury. The social differences in health were reduced strongly after adjustment for work factors (psychological demands excluded) by 24-58% according to sex and health outcomes. The strongest impacts were found for decision latitude, ergonomic, physical, and chemical exposures, as well as for work schedules. A detailed analysis allowed us to identify more precisely the contributing occupational factors. It suggests that concerted prevention of occupational risk factors would be useful not only to improve health at work, but also to reduce social inequalities in health.     

Psychosocial work factors and long sickness absence in Europe

Background:

Studies exploring a wide range of psychosocial work factors separately and together in association with long sickness absence are still lacking.

Objectives:

The objective of this study was to explore the associations between psychosocial work factors measured following a comprehensive instrument (Copenhagen psychosocial questionnaire, COPSOQ) and long sickness absence (>7 days/year) in European employees of 34 countries. An additional objective was to study the differences in these associations according to gender and countries.

Methods:

The study population consisted of 16 120 male and 16 588 female employees from the 2010 European working conditions survey. Twenty-five psychosocial work factors were explored. Statistical analysis was performed using multilevel logistic regression models and interaction testing.

Results:

When studied together in the same model, factors related to job demands (quantitative demands and demands for hiding emotions), possibilities for development, social relationships (role conflicts, quality of leadership, social support, and sense of community), workplace violence (physical violence, bullying, and discrimination), shift work, and job promotion were associated with long sickness absence. Almost no difference was observed according to gender and country.

Conclusions:

Comprehensive prevention policies oriented to psychosocial work factors may be useful to prevent long sickness absence at European level.     

Psychosocial work factors and long sickness absence in Europe

Abstract

Background: Studies exploring a wide range of psychosocial work factors separately and together in association with long sickness absence are still lacking.

Objectives: The objective of this study was to explore the associations between psychosocial work factors measured following a comprehensive instrument (Copenhagen psychosocial questionnaire, COPSOQ) and long sickness absence (>7 days/year) in European employees of 34 countries. An additional objective was to study the differences in these associations according to gender and countries.

Methods: The study population consisted of 16?120 male and 16?588 female employees from the 2010 European working conditions survey. Twenty-five psychosocial work factors were explored. Statistical analysis was performed using multilevel logistic regression models and interaction testing.

Results: When studied together in the same model, factors related to job demands (quantitative demands and demands for hiding emotions), possibilities for development, social relationships (role conflicts, quality of leadership, social support, and sense of community), workplace violence (physical violence, bullying, and discrimination), shift work, and job promotion were associated with long sickness absence. Almost no difference was observed according to gender and country.

Violence toward mental health staff and safety in the work environment

BACKGROUND: An increasing number of violent episodes toward staff were noted at a university department of psychiatry. A multidisciplinary committee was formed consisting of psychiatrists, biostatisticians, psychologists, nurses, administrators, data managers, social workers, security services, educators on personal safety and an attorney to address the problem. AIM: To determine the prevalence of violence toward mental health staff, clinicians and non-clinicians, the trend of violence over time, gather more detail about the violent events, the personal struggle of staff affected and establish suggestions for intervention. METHODS: A workplace violence survey was designed to query staff experiences of endangerment, threats, assaults, age, sex and discipline, years in the field, treatment setting, sense of safety and proclivity to press charges. RESULTS: Of 742 surveys distributed, respondents returned 380 (response rate 51%). Forty-three percent of respondents reported being threatened and 25% assaulted. Threats and assaults increased significantly (P<0.001) over all the time periods queried based on Poisson regression analysis. Work experience was a protective factor (P<0.001), but not a guarantee against violent events. CONCLUSION: Threats and assaults on mental health staff have a substantial prevalence and are increasing in our psychiatric population. Practical recommendations derived from our study but in need of further research for confirmation are: (1) multidisciplinary personal safety training to enhance team-building, improve communication and help prevent violent events and (2) establishment of post-event protocols to assist staff-victims and administrators navigate through complex issues occurring after violent events.     

Prospective study of physical and psychosocial risk factors for sickness absence

AIM: To investigate the associations between psychosocial and physical work environment exposures and sickness absence from work taking into account health, health behaviour and employer characteristics known to affect sickness absence. METHODS: In 1995, a random sample of 5574 employees aged 18-64 years were interviewed. In 2000, 3792 of those still employed supplied data on days absent from work the year preceding the date of follow-up. Associations between risk factors at baseline and sickness absence at follow-up were studied. Logistic regression analyses were performed. RESULTS: Sickness absence was associated with working with arms lifted/hands twisted, extreme bending/stooping of the back/neck, repetitive monotonous work, low skill discretion, low decision authority, obesity, current and former smoking, poor self-rated health, female gender, increasing age and public employer. The aetiological fraction attributable to differences in work environment exposures was calculated to be 40%. CONCLUSION: The study suggests a potential for reducing sickness absence through multifactorial interventions towards smoking, obesity, physical and psychosocial work environment exposures. The study showed that differences in work environment exposures account for 40% of the cases of high sickness absence.     

Workplace bullying and sickness absence in hospital staff

OBJECTIVES—In the past, evidence on the negative consequences of workplace bullying has been limited to cross sectional studies of self reported bullying. In this study, these consequences were examined prospectively by focusing on sickness absence in hospital staff.
METHODS—The Poisson regression analyses of medically certified spells (4 days) and self certified spells (1-3 days) of sickness absence, relating to bullying and other predictors of health, were based on a cohort of 674 male and 4981 female hospital employees aged 19-63 years. Data on sickness absence were gathered from employers' registers. Bullying and other predictors of health were measured by a questionnaire survey.
RESULTS—302 (5%) of the employees reported being victims of bullying. They did not differ from the other employees in terms of sex, age, occupation, type of job contract, hours of work, income, smoking, alcohol consumption, or physical activity. Victims of bullying had higher body mass and prevalence of chronic disease, and their rates of medically and self certified spells of sickness absence were 1.5 (95% confidence interval (95% CI) 1.3 to 1.7) and 1.2 (1.1 to 1.4) times higher than those of the rest of the staff. The rate ratios remained significant after adjustment for demographic data, occupational background, behaviour involving risks to health, baseline health status, and sickness absence.
CONCLUSION—Workplace bullying is associated with an increase in the sickness absenteeism of the hospital staff. Targets of bullying seem not to belong to any distinct group with certain demographic characteristics or occupational background.

Risk factors in health, work environment, smoking status, and organizational context for work disability

BACKGROUND: This study examines the associations between health, work environment exposures, smoking status, and organizational context and work disability. METHODS: In a sample of 3,318 Danish employees, respondents were interviewed by telephone in 1995 about health, work environment, smoking status and organizational context of the workplace. In 1997, a follow-up to assess employment status was conducted using The Statistical Register of Transfer Payments, Statistics Denmark. RESULTS: Work disability is predicted by work environment, smoking status of the individual employee, and by organizational level factors at the workplace. Although poor mental health, chronic bronchitis or musculoskeletal symptoms in neck or shoulders were equally distributed at baseline among type of company, the 2-year incidence of work disability was higher in traditionally organized workplaces than in flexibly organized workplaces. CONCLUSION: The study suggests a potential for reducing health-related work disability from work through flexible organization of the workplace.     

The influence of psychosocial factors at work and life style on health and work ability among professional workers

OBJECTIVES: The purpose of this article is to explore the associations of psychosocial factors at work, life style, and stressful life events on health and work ability among white-collar workers. METHODS: A cross-sectional survey was conducted among workers in commercial services (n = 1141). The main outcome variables were work ability, measured by the work ability index (WAI), and mental and physical health, measured by the Short-Form Health Survey (SF-12). Individual characteristics, psychosocial factors at work, stressful life events, and lifestyle factors were determined by a questionnaire. Maximum oxygen uptake, weight, height, and biceps strength were measured during a physical examination. RESULTS: Work ability of white-collar workers in commercial services industry was strongly associated with psychosocial factors at work such as teamwork, stress handling, and self-development and, to a lesser extent, with stressful life events, lack of physical activity, and obesity. Determinants of mental health were very similar to those of work ability, whereas physical health was influenced primarily by life style factors. With respect to work ability, the influence of unhealthy life style seems more important for older workers, than for their younger colleagues. CONCLUSION: Among white-collar workers mental and physical health were of equal importance to work ability, but only mental health and work ability shared the same determinants. The strong associations between psychosocial factors at work and mental health and work ability suggest that in this study population health promotion should address working conditions rather than individual life style factors.     

Influence of change in psychosocial work characteristics on sickness absence: The Whitehall II Study

OBJECTIVES: To study the influence of change in self perceived psychosocial work characteristics on subsequent rates of sickness absence. METHODS: Prospective cohort study of British civil service employees. Job control, job demands, and work social supports were measured in 1985/88 and in 1991/93. Analyses included 3817 British civil servants with sickness absence records at baseline (1985-89) and for two follow up periods, early (1994-95) and later follow up (1996-98). RESULTS: Change in work characteristics predicted subsequent incidence of long spells of sickness absence (>7 days) in the early follow up period after adjustment for covariates including baseline work characteristics, health status, and sickness absence. Adjusted rate ratios were 1.23 (95% CI 1.03 to 1.46) for decreased compared with stable decision latitude; 1.17 (95% CI 1.01 to 1.36) for increased compared with stable job demands and 0.79 (95% CI 0.67 to 0.93) for increased compared with stable work social support. These associations were also seen in a sub-sample who did not change employment grade. In the later follow up period, associations between work change and long spells of sickness absence were similar for decision latitude, less pronounced for job demands, and no longer apparent for social supports. Changes in work characteristics were not associated with subsequent short spells of sickness absence (相似文献

Occupational and social variation in subjective health complaints

OBJECTIVES: Occupational and social factors are thought to be important determinants of health inequality. The aim of this study was to examine the relationships between occupation, lifestyle and subjective health complaints (SHC). METHODS: SHC and self-reported sickness absence were recorded in a cross-sectional study of 662 individuals aged between 16 and 67 from five occupational groups: blue-collar, school/education, health service, white-collar and service. Differences in SHC and sickness absence were investigated. A model of sociodemographic, lifestyle and work-related factors was tested to examine associations with SHC. RESULTS: Few differences in SHC and sickness absence were found when educational level, age and gender were controlled for. Female health service workers did, however, show significantly higher prevalence of pseudoneurological complaints compared with white-collar workers. Male blue-collar workers had significantly higher frequency of sickness absence than white-collar workers; otherwise, there were no significant differences in frequency and duration of sickness absence. The model explained very little of the variance of SHC (R(2)(adj) = 0.15) and occupational group was not significantly associated with health. Physical workload and sleep quality showed significant relationships with SHC for both genders. Education, however, was a significant factor for women only. CONCLUSIONS: The differences in health found between major occupational groups in this sample were mainly explained by gender differences. Sociodemographic, lifestyle and work-related factors explained little of the variance in SHC, suggesting that factors such as psychological demands, perceived job stress, coping and other psychological factors might be of stronger importance for SHC.     

Receptionists' perceptions of violence in general practice

BACKGROUND: Violence and threatening behaviour towards health care employees is a recognized hazard. There is a lack of research into the perceptions of general practice (GP) receptionists about this important workplace hazard. AIM: To determine the factors that influence reception staff perceptions regarding the risk of future violent and threatening incidents at work. METHODS: A cross-sectional survey using a self-administered postal questionnaire was carried out among reception staff working in 49 GPs in two UK National Health Service Primary Care Trusts. RESULTS: Forty-nine (72%) practices agreed to participate. Two hundred and seven (68%) reception staff participated. Receptionists who reported having been threatened or attacked in the past 12 months were more likely to be worried about being threatened [odds ratio (OR) 4.9; 95% confidence interval (CI) 2.0-11.8] or attacked (OR 4.6; 95% CI 1.8-11.2) in the future. Receptionists with higher neuroticism scores were more worried about the future possibility of violence. Staff who felt safe and supported at work (P = 0.003) and staff who had lower background sources of stress at work (P < 0.001) were less likely to feel they would be threatened or attacked at work. Staff who had received training about violent and abusive incidents felt safer at work (OR = 1.27; 95% CI 1.04-1.55). CONCLUSION: Previous episodes of threats or attacks at work make receptionists more worried about future episodes. Factors which reduce reception staff anxieties about violence and threat at work are working in a supportive environment where work stressors are controlled and receiving training on how to deal with violent, threatening and difficult behaviour.

Constructing health and sickness in the context of motherhood and paid work

Changes in the labour market, especially the rise in the employment of women (lone or partnered) with children, alongside an increased policy emphasis on work as a component of active citizenship for men and women, have stimulated the development of research examining the balance between work and home. Although sociologists have long been interested in the interface between the spheres of paid work and domestic life, understandings of the subjective experience of health and illness have tended to keep the domains of family and work separate. This paper addresses the construction of health and illness as operating at the interface between the worlds of work and home. Interviews were conducted with 30 mothers in paid work and having primary school aged children; the study was located in Edinburgh, Scotland. Through an analysis of the interview accounts, this paper examines respondents' experiences and constructions of health, sickness and wellbeing in themselves and in their children. Four areas are discussed: respondents' accounts of the effects of caring and providing on their own health; respondents' accounts of the influence of workplace relationships in the construction of sickness; respondents' accounts of negotiating absence for their children's sickness and how they made sense of and defined child sickness. We argue that managing sickness, itself an anticipated but unpredictable event, gives analytical purchase to understanding the values and practices that characterise the interrelationship between work and family life. The intersections of home and work operate powerfully in respondents' constructions of health and sickness, and the analysis demonstrates how these are played out in everyday life, at home and at work.     

A retrospective study of return to work following surgery

BACKGROUND: Sickness absence following surgery accounts for significant periods of sickness absence from employment. The duration of absence following two surgical procedures: benign abdominal hysterectomy (BAH) and Birmingham hip resurfacing (BHR) was explored. AIM: To identify what advice patients who had undergone BAH or BHR surgery were given regarding their likely sickness absence duration and to compare this with their reported absence duration. METHOD: In all, 453 patients who had undergone BAH or BHR surgery during 2004 were contacted by postal questionnaire and the results were statistically analysed. RESULTS: The advice given to patients to refrain from work varied from 4 weeks to >15 weeks for BAH surgery which was inconsistent with evidence-based guidance provided by the Department of Work and Pensions. The advice for BHR varied from <4 weeks to >15 weeks. Advice given by health care professionals appeared to have the greatest influence on return to work times with patients tending to adhere to any advice that is given irrespective of its duration. Twenty-two (29%) BAH patients and thirty-six (43%) BHR patients reported that their employers provided temporary work modifications when they returned to work; however, this support appeared to have no effect on their sickness absence duration. CONCLUSION: Health care professional advice regarding expected sickness absence duration influenced absence duration. The awareness and use of more consistent evidence-based guidance may be beneficial for all involved in this process.     

A prospective study of psychosocial risk factors and absence due to musculoskeletal disorders--implications for occupational screening

OBJECTIVES: There is considerable evidence documenting the association between psychosocial risk factors and work disability due to musculoskeletal disorders, and this has prompted suggestions that psychosocial screening should be administered in the workplace in order to identify individuals at risk of prolonged absence. However, the predictive value of psychosocial risk factors on return-to-work is largely unknown. The present study aimed to explore the predictive relationship between psychosocial risk factors and absence due to musculoskeletal disorders of the lower back and upper limbs. METHODS: A prospective study of 4637 workers from a large, multi-site company in the UK was conducted in which a wide range of established questionnaires were used to collect baseline psychosocial data. Respondents were then followed over the ensuing 15 months, and absence due to musculoskeletal disorders was recorded. RESULTS: 219 workers took absence due to musculoskeletal disorders. Detrimental cut-off scores (risks) on the psychosocial instruments were established, and it was found that work-related psychosocial risk factors predicted the likelihood of a future spell of absence (odds ratios ranging between 1.6 and 3.2), but not the duration of that absence. CONCLUSIONS: Although work-related psychosocial factors were associated with the occurrence of absence due to musculoskeletal disorders, these findings do not lend support to the use of routine occupational psychosocial screening in order to predict prolonged absence.     

The interaction between general practitioners and occupational health professionals in relation to rehabilitation for work: a Delphi study

BACKGROUND: Anecdotally, communication between general practitioners (GPs) and occupational health professionals is poor and acts as a barrier to successful rehabilitation for work. It is not known how widely this view is held by the many stakeholders in rehabilitation for work, or how important the observation is in its effect. METHODS: A Delphi study was conducted by initial semi-structured telephone interview, followed by a three-round collation and feedback of opinion by e-mail. The 25 participants were identified by suggestion within the study process for their position as key informants within a wide range of stakeholders. RESULTS: The process generated a consensus statement which identifies the extremely important nature of rehabilitation for work, the crucial role by GPs, the central role of occupational health professionals in case management and the barrier represented by the often very poor communication between them. CONCLUSION: The way forward is to improve communication by mutual education and understanding and a team approach to rehabilitation strategy. This may be facilitated by the GPs who work in occupational health and disability assessment and the involvement of other health professionals to great benefit for all stakeholders.     

Influence of work environment on emotional health in a health care setting

BACKGROUND: Radical changes are taking place in health care services and might be expected to cause job dissatisfaction, absenteeism, somatic complaints and mental health problems. Research in this area is limited and focused primarily on nurses. AIM: To understand the impact of the work environment on the emotional health of doctors and nurses in a general hospital setting. METHODS: Cross-sectional study using self-reported questionnaires including the General Health Questionnaire, the Posttraumatic Stress Disorder (PTSD) Checklist for Civilians, the Trauma Experiences and Work Environment Scale. RESULTS: The response rates for the study were 28% (60) for doctors and 54% (431) for nurses. Whilst the prevalences of psychiatric disorder, anxiety, depression and PTSD were higher for doctors compared with nurses, this was not statistically significant. Both groups reported witnessing someone badly injured or killed as their most distressing experience (doctors 46% versus nurses 41%). Using multiple logistic regression, significant predictors of emotional health was task orientation for doctors (OR = 1.96, 95% CI = 1.1-3.6), and PTSD (OR = 17.2, 95% CI = 6.0-49.6), work pressure (OR = 1.2, 95% CI = 1.01-1.4) and innovation (OR = 0.81, 95% CI = 0.70-0.94) for nurses. CONCLUSION: The prevalence of psychiatric disorder among the doctors and nurses was similar to that in Britain. Elements of the work environment did impact on the emotional health of health care workers. Organizational development initiatives should include employee mental health issues in order to create a more positive work environment.
