Patterns of working and living conditions: A holistic, multivariate approach to occupational health studies

Assessing the Psychosocial Work Environment in Relation to Mental Health: A Comprehensive Approach

OBJECTIVES

Prevailing job stress models encourage a multidimensional view of the psychosocial work environment and highlight the role that multiple co-occurring stressors play in the aetiology of mental health problems. In this study, we develop a latent typology of psychosocial work environment profiles to describe how a comprehensive array of job stressors are clustered in the Canadian labour market. We also examine the association between these latent psychosocial work environment profiles and several indicators of mental health.

METHODS

Data were collected from 6408 workers who completed the Canadian National Psychosocial Work Environment Survey. Psychosocial work exposures were measured using standard items from the Copenhagen Psychosocial Questionnaire. We employed latent profile analyses to identify groups of individuals with similar psychosocial work environment profiles. We used log-linear regression models to examine the association between latent psychosocial work environment profiles and burnout, stress, and cognitive strain.

RESULTS

Four distinct groups with highly divergent psychosocial work environment profiles were identified. Adjusting for a range of demographic and socioeconomic factors, latent psychosocial work environment profiles were strongly related to mental health. Individuals who reported exposure to a comprehensive array of psychosocial job stressors (11% prevalence) reported the highest probability of burnout (PR: 7.51, 95% confidence interval [CI]: 5.56-10.15), stress (PR: 8.98, 95% CI: 6.20-13.0), and cognitive strain (PR: 7.29, 95% CI: 5.02-10.60).

CONCLUSIONS

Findings suggest that psychosocial work stressors are tightly clustered in the Canadian labour market, and that the clustering of work stressors is strongly associated with adverse mental health outcomes. Future scholarship may benefit from adopting a more comprehensive approach to the assessment of psychosocial job quality as a determinant of health and well-being.

Workplace gender composition and psychological distress: the importance of the psychosocial work environment

Background

Health consequences of the gender segregated labour market have previously been demonstrated in the light of gender composition of occupations and workplaces, with somewhat mixed results. Associations between the gender composition and health status have been suggested to be shaped by the psychosocial work environment. The present study aims to analyse how workplace gender composition is related to psychological distress and to explore the importance of the psychosocial work environment for psychological distress at workplaces with different gender compositions.

Methods

The study population consisted of participants from the Northern Swedish Cohort with a registered workplace in 2007 when the participants were 42 years old (N = 795). Questionnaire data were supplemented with register data on the gender composition of the participants’ workplaces divided into three groups: workplaces with more women, mixed workplaces, and workplaces with more men. Associations between psychological distress and gender composition were analysed with multivariate logistic regression analysis adjusting for socioeconomic position, previous psychological distress, psychosocial work environment factors and gender. Logistic regression analyses (including interaction terms for gender composition and each work environment factor) were also used to assess differential associations between psychosocial work factor and psychological distress according to gender composition.

Results

Working at workplaces with a mixed gender composition was related to a higher likelihood of psychological distress compared to workplaces with more men, after adjustments for socioeconomic position, psychological distress at age 21, psychosocial work environment factors and gender. Psychosocial work environment factors did not explain the association between gender composition and psychological distress.

Conclusions

The association between gender composition and psychological distress cannot be explained by differences in the perception of the psychosocial work environment and thus the work environment hypothesis is not supported. Workplaces with a mixed gender composition needs further research attention to explain the negative development of psychological distress during working life for both women and men at these workplaces.

Privatizing health care in times of new public management: Investigating the role of psychological empowerment using cluster analysis

Although privatization within health care is usually justified using arguments based on efficiency and productivity, the empirical investigations underpinning such arguments are few and ambiguous in their results. Presenting a new theoretical and analytical approach to this research field, we argue that psychological empowerment, reflecting individuals' intrinsic change motivation state, is a crucial prerequisite for the transformation of a nonprofit health care organization to a for-profit one. The general aims of this study were to explore empowerment cognitions during a privatization, to relate these to a selection of key work-related outcome variables, and to identify the effects of privatization in terms of individual level changes in empowerment after privatization. A sample of health care workers (n = 210) provided survey longitudinal data that were analyzed using cluster analysis. Eight clusters were identified at both pre- and postprivatization with each cluster mirroring specific empowerment patterns: Empowered, In Control, Quasi-Empowered, Competent/Normed, Reference, Underused, Misfit, and Powerless. The clusters discriminated on positive work attitudes, mental health complaints, and turnover intentions. The analysis also revealed the complexity of privatization in that a homogenization as well as a differentiation tendency was observed, thereby implicating both socio-structural equality and inequality effects. The results highlighted the relevance of allocating importance to health care workers' psychological empowerment during the privatization process, and of viewing such organizational transformations not as simple shifts in the state of affairs, but as nonlinear processes involving dynamic changes in individual perceptions over time.

The link between parental allergy and offspring allergic and nonallergic rhinitis

BACKGROUND

Parental allergy-related disease increases the risk for rhinitis, but it remains unknown how different phenotypes of parental allergy affect this risk. The aim of this study was to investigate how parental hay fever, asthma, and eczema affect the risk of allergic rhinitis (AR) and nonallergic rhinitis (NAR) at 8 years of age.

METHODS

Information on 2413 children from a population-based birth cohort was used combining questionnaire data and IgE to inhalant allergens. Logistic regression was used to estimate the association between parental allergy-related disease and AR and NAR. In addition, cluster analysis was used to search for latent phenotypes of heredity likely to be associated with AR and NAR.

RESULTS

At age 8 years, 13.8% of the children had AR, while 6.4% had NAR. Parental isolated hay fever increased the odds of AR (OR 2.2, 95% CI 1.6-3.2), whereas isolated asthma or eczema did not. The odds of NAR increased when one parent had two or more allergy-related diseases. In the cluster analysis, the highest proportion of AR, 37.5%, was seen in a cluster where both parents had hay fever and pollen allergy and that of NAR, 11.0%, in a cluster where one parent had hay fever, pollen allergy, and eczema.

CONCLUSIONS

Parental allergy-related disease may be an important risk factor for NAR as well as AR, and the risk is comparable for maternal and paternal allergy. Parental hay fever seems to be the dominating hereditary risk factor for AR.

Patterns of gender equality at workplaces and psychological distress

Research in the field of occupational health often uses a risk factor approach which has been criticized by feminist researchers for not considering the combination of many different variables that are at play simultaneously. To overcome this shortcoming this study aims to identify patterns of gender equality at workplaces and to investigate how these patterns are associated with psychological distress. Questionnaire data from the Northern Swedish Cohort (n = 715) have been analysed and supplemented with register data about the participants' workplaces. The register data were used to create gender equality indicators of women/men ratios of number of employees, educational level, salary and parental leave. Cluster analysis was used to identify patterns of gender equality at the workplaces. Differences in psychological distress between the clusters were analysed by chi-square test and logistic regression analyses, adjusting for individual socio-demographics and previous psychological distress. The cluster analysis resulted in six distinctive clusters with different patterns of gender equality at the workplaces that were associated to psychological distress for women but not for men. For women the highest odds of psychological distress was found on traditionally gender unequal workplaces. The lowest overall occurrence of psychological distress as well as same occurrence for women and men was found on the most gender equal workplaces. The results from this study support the convergence hypothesis as gender equality at the workplace does not only relate to better mental health for women, but also more similar occurrence of mental ill-health between women and men. This study highlights the importance of utilizing a multidimensional view of gender equality to understand its association to health outcomes. Health policies need to consider gender equality at the workplace level as a social determinant of health that is of importance for reducing differences in health outcomes for women and men.

Falling between two stools; how a weak co-operation between the social security and the unemployment agencies obstructs rehabilitation of unemployed sick-listed persons

PURPOSE

To explore significant factors behind the weak co-operation between local social insurance and unemployment agencies impairing the rehabilitation of unemployed sick-listed persons.

METHOD

Individual, semi-structured face-to-face interviews with main actors directly involved in the sick-listing and rehabilitation process were conducted in the year 2000. In all 39 persons were interviewed: 25 professionals (physicians, public employment and social insurance officers) and 14 clients. Data were analysed according to Grounded theory method.

RESULTS

The majority of unemployed sick-listed persons were declared too sick to work and were erased from the unemployment registers. This measure weakened the incentives for co-operation between the two main rehabilitation actors. The implication was that the unemployed sick-listed persons lost the opportunity of the co-ordinated rehabilitation they were entitled to. Three significant factors behind this process were identified by the main actors: indistinct regulation of co-operation, shifting political goals over time and conflicting goals between agencies; the last factor mainly a consequence of the other two.

CONCLUSIONS

The findings suggest that labour market changes and manifest political goals influence the rehabilitation efforts giving low priority to difficult-to-place individuals such as unemployed sick-listed persons. In fact, a labour market problem turns into a medical problem. The hypothesis needs further testing in quantitative studies.

Coping processes in a multidisciplinary healthcare team--a comparison of nurses in cancer care and hospital chaplains

The purpose of this paper is to compare the coping processes of hospital chaplains and nurses in cancer care and to discuss the findings in relation to work and stress in a multidisciplinary team. The results of the research question--'what coping processes are used when confronting existential issues?'--reveal that, as members of the multidisciplinary healthcare team, both professions need space in work for significance; the nurse needs to be able to help the patient 'do good' and the hospital chaplain needs to be available to meet the patient. Boundary demarcation was found to be the most common coping strategy.

Does the job demand—control model correspond to externally assessed demands and control for both women and men?

Aims: To explore externally assessed demands and control for both women and men in each of the groups of the job demand—control (JDC) model, which itself was based on self-reported data. A specific aim was to better understand why health conditions among women with active jobs were as bad as those among women with high-strain jobs in some earlier studies. Methods: Expert assessments were made through direct observation and interviews concerning time pressure, hindrances, influence, and creative work tasks. The sample consisted of 203 men and women in 85 occupations. The four groups of the JDC model (high strain, low strain, active, and passive) were constructed from self-reported data. Results: Most comparative analyses of the JDC groups showed that external assessments corresponded to self-reports in the expected direction for both women and men, although not always statistically significant. However, in the active job situation, external assessments deviated from self-reports in different directions for women and men. Women had more hindrances and less influence over their work, while the situation was reversed for men. Women in active jobs worked more often than men in an organization with mostly female staff and in a predominantly female occupation. Conclusions: Associations between self-reported working conditions and health might be underestimated among women reporting an active job situation. Our findings contribute to the discussion on why the results in some studies show that active jobs among women are as hazardous for health as high-strain jobs.

Long-term sickness absence due to burnout: absentees' experiences

In the late 1990s, there was a marked increase in Sweden in long-term sickness absence with mental diagnoses. In the extensive research on burnout, little attention has been paid to the link with sickness absence. Our aim in this study was to discover what caused burnout, or such severe stress that it led to long-term sickness absence (> 28 days). We interviewed 32 individuals on long-term sickness absence with a diagnosis of burnout and used grounded theory to analyze the data. We believe that events prior to the sickness absence can be understood as a process of emotional deprivation, and we described the process in terms of a flight of stairs with eight steps: "The Burnout Stairs." We argue that the emotion conveying the process of emotional deprivation is unacknowledged shame, which has its basis in poor social relations at work. We discuss the study's limitations and the need for further research in this field.

Worker participation in change processes in a Danish industrial setting

BACKGROUND

Improving the design, management and organization of work may be an important step in improving occupational health. An intervention, guided by the principles of participatory action research (PAR), is directed at traditional work environment problems in the epoxy plastic industry, that is, eczema and accident-related injuries.

METHODS

The study population consisted of employees at two wind turbine- manufacturing plants. A quasi-experimental design was employed with before and after measurements and a comparison group with a 3(1/2) year follow-up period.

RESULTS

The role of employee elected safety representatives was changed from one of controlling and "policing" to that of safety advisors. The attitudes of employees also changed, from an individualistic understanding of safety as the responsibility of the single employee, to a more collective understanding of safety as being everyone's shared responsibility. Structural changes led to a less hierarchical management system. This process led eventually to the establishment of self-governing work groups in which each member had a well-defined area of responsibility. The change process was associated with improvements in the psychosocial work environment and safety climate, a 66% reduction in the incidence of eczema, and a 48.6% reduction in the incidence of occupational accidents. In the comparison population, a twin factory under the same company, similar but delayed and less dramatic changes also occurred.

CONCLUSIONS

Implementation of a comprehensive intervention was followed by improved employee perceptions of the company's safety standards and the psychosocial work environment, as well as by substantial reductions in the incidence of eczema and occupational accidents.

Awkward work postures: association with occupational gender segregation

BACKGROUND

Segregation of men and women into different jobs is often cited as one of the most plausible explanations for gender differences in exposure and musculoskeletal disorders.

METHODS

Direct measurements of sitting, arm, and trunk postures were taken with two different technical instruments on 156 subjects (78 matched pairs of one female and one male worker) over one full workday in diverse labor markets.

RESULTS

Exposure differences between workers were strongly associated with vertical occupational segregation (measured as level of status/authority). The results showed that this association was strongest for female-dominated jobs. Workers in female-dominated jobs with a low status/authority experienced longer duration in standing posture (P = 0.001), and higher frequency of arm elevation (P = 0.028 and 0.040 for the dominant and the non-dominant arm, respectively). They also had longer duration of work with bent trunk compared to corresponding workers with high status/authority (P = 0.035). The association was less pronounced for male-dominated jobs, and no such association was found for gender-integrated jobs.

CONCLUSION

The findings have implications for prevention as well as for future research.

Are Trends in Work and Health Conditions Interrelated? A Study of Swedish Hospital Employees in the 1990s

Swedish hospital personnel were followed over an 8-year period, characterized by staff redundancies and restructuring processes. Self-rated and administrative data sets from 1994 to 2001 allowed for studying long-term consequences of organizational instability for staff health and work conditions. The aim was to identify, on a work-unit level, trends in work and health conditions and their interdependence. Regression analysis showed a downward trend in mental health and an upward trend in long-term sick leave. Increasing trends of work demands were accompanied by deteriorating mental health, and decreasing time to plan work showed the strongest association with increasing long-term sick leave. Job satisfaction and support were decreasing. A stable short-term sick leave rate over years related to lack of support.

Do work technique and musculoskeletal symptoms differ between men and women performing the same type of work tasks?

Musculoskeletal disorders are more common among women than among men. When comparing the difference between men and women in the prevalence of musculoskeletal disorders, methodological problems arise as men and women seldom perform the same type of activities, neither at work nor at home. The main objective of this cross-sectional case study was to compare work technique and self-reported musculoskeletal symptoms between men and women performing the same type of work tasks within a metal industry. Other factors, such as leisure activities, were also taken into consideration. Three data collection methods were used; questionnaire, interviews and systematic observations. The results from the observations revealed that women worked more frequently and during longer times with their hands above shoulder height than men. Working with hands above shoulder height is considered a risk factor for neck and shoulder disorders according to previous studies. Workplace design factors were probably a reason for differences in working technique between men and women. A higher proportion of women than men reported shoulder symptoms. Women spent more time on household activities than men, which indicates a higher total workload in paid and unpaid work.

Health-Related Quality of Life and Hand Eczema—A Comparison of Two Instruments, Including Factor Analysis

Hand eczema is a disease of long duration, affecting the individual and society. The purpose of this study of 100 patients (51 females and 49 males) at an occupational dermatology clinic was to investigate whether the generic questionnaire Short Form-36 (SF-36), and the dermatology-specific Dermatology Life Quality Index (DLQI) are appropriate for assessing health-related quality of life (HRQL) in patients with hand eczema, and whether gender differences in HRQL could be detected. HRQL was affected by hand eczema, measured with both SF-36 and DLQI. The SF-36 showed more impaired HRQL for females than for males, in the mental health dimension, whereas no gender-related differences were detected with the DLQI. To compare the instruments we used factor analysis, with a polychoric correlation matrix as input, thus taking the ordinal aspect of the data into account. There was a high correlation between the instruments for physical health, but lower for mental health. In this context our interpretation of the factor analysis is that the SF-36 measures mental health better than the DLQI. The SF-36 therefore appears suitable for use in future studies for measuring HRQL, and gender differences in HRQL, in persons with reported hand eczema.
