TL;DR: Results suggest that psychological job characteristics are more similar across national boundaries than across occupations.
Abstract: This article consists of three parts. Part 1 discusses the Job Content Questionnaire (JCQ), designed to measure scales assessing psychological demands, decision latitude, social support, physical demands, and job insecurity. Part 2 reports the cross-national validity, for men and women, of the JCQ scales in six broadly representative populations from four advanced industrial societies: the United States, Canada, the Netherlands and Japan. JCQ scale means, standard deviations, reliabilities and correlations are compared. Part 3 reviews comparison of the intercountry and interoccupation differences in the scales, discusses specific scales issues and discusses the implications of the study for interpretation of psychosocial job asessment questionnaires.

TL;DR: The results indicate that women exposed to high job strain are at higher risk of developing preeclampsia and, to a lesser extent, gestational hypertension.
Abstract: In a case-control study we assessed whether exposure to high job strain during the first 20 weeks of pregnancy increases the risk of preeclampsia and gestational hypertension. Cases (128 with preeclampsia and 201 with gestational hypertension) and controls (N = 401) were primiparous women who had a paid occupation for at least 1 week during the first 20 weeks of their pregnancy and who delivered between 1984 and 1986 in 10 hospitals of Quebec, Canada. Based on their job title, we assigned women scores of psychological demand and decision latitude derived from the National Population Health Survey and classified these women as exposed to high (high demand, low latitude) versus low (low demand, high latitude) job strain. Women exposed to high job strain were more likely to develop preeclampsia [adjusted odds ratio (aOR) = 2.1; 95% confidence interval (CI) = 1.1-4.1] than women exposed to low job strain. The risk was quite similar for women exposed to a full-time, high strain job (> or =35 hours per week) (aOR = 2.0) than in a part-time, high strain job (aOR = 1.8). High job strain increased the risk of gestational hypertension slightly (aOR = 1.3; 95% CI = 0.8-2.2). These results indicate that women exposed to high job strain are at higher risk of developing preeclampsia and, to a lesser extent, gestational hypertension.

TL;DR: Little evidence that women diagnosed with breast cancer experience discrimination at work is found, which may be helpful for working women concerned about employment after breast cancer.
Abstract: Background Breast cancer may adversely affect work experience. We assessed whether there was evidence of discrimination at work, defined as negative or involuntary changes in employment situation (including changes in position, wages, and other conditions), associated with a breast cancer diagnosis in a population-based retrospective cohort study conducted in Quebec, Canada. Methods The study was based on the consecutive series of women aged less then 60 years when first treated for breast cancer (identified through the Quebec Tumor Registry) and a random sample of frequency-matched women living in Quebec (identified from provincial health care files) who had never been diagnosed with cancer. Eligibility for the study was restricted to women who were employed at the time of diagnosis (for breast cancer survivors) or the same calendar period (for women in the comparison group). We conducted telephone interviews of eligible women 3 years after diagnosis for 646 survivors or after the matched calendar period for 890 women in the comparison group. Binomial regression was used to evaluate the relationship between having breast cancer and work situation. All statistical tests were two-sided. Results Working conditions were similar between the two groups at the beginning of follow-up. After 3 years, slightly more survivors (21%) than women in the comparison group (15%) were unemployed (adjusted relative risk for being unemployed = 1.29, 95% confidence interval = 1.05 to 1.59), although most women who were not working (84% of unemployed survivors and 76% of unemployed women in the comparison group) said that the decision to stop working was their own. Among women still employed, no deterioration in working conditions was observed in either group. Conclusion We found little evidence that women diagnosed with breast cancer experience discrimination at work. This information may be helpful for working women concerned about employment after breast cancer.

TL;DR: This exploratory qualitative study was conducted among 13 breast cancer survivors who had paid employment at diagnosis, returned to work afterwards, and mentioned work‐related problems to a clinic nurse or physician, suggesting that health professionals’ behaviour may influence women's work experience right from diagnosis.
Abstract: People treated for cancer have reported a variety of problems at work. However, there is little data on work experience after breast cancer, particularly for women treated in recent years. This exploratory qualitative study was conducted among 13 breast cancer survivors who had paid employment at diagnosis, returned to work afterwards, and mentioned work-related problems to a clinic nurse or physician. Unstructured, thematic interviews were undertaken. Qualitative thematic content analysis was conducted to identify and group themes which emerged from participants' discourse. Women in various types of jobs reported experiencing job loss, demotion, unwanted changes in tasks, problems with the employer and co-workers, personal changes in attitudes to work and diminished physical capacity. These work problems also preoccupied people treated for cancer more than two decades ago. New areas of concern also emerged: possible positive and negative effects of learning (implicitly or explicitly) about the diagnosis while at work and lack of discussion with health professionals about work and return-to-work issues, suggesting that health professionals' behaviour may influence women's work experience right from diagnosis. The identification of these new problems and confirmation of previously reported ones underlines the pertinence of determining how important and widespread these problems are in women now being treated for breast cancer.

TL;DR: Procedural and relational justice can be considered a different and complementary model to the DCS and ERI models and future studies should evaluate the effect of change in exposure to organisational justice on employees' mental health over time.
Abstract: The models most commonly used, to study the effects of psychosocial work factors on workers' health, are the demand-control-support (DCS) model and Effort-Reward Imbalance (ERI) model. An emerging body of research has identified Organisational Justice as another model that can help to explain deleterious health effects. This review aimed: (1) to identify prospective studies of the associations between organisational justice and mental health in industrialised countries from 1990 to 2010; (2) to evaluate the extent to which organisational justice has an effect on mental health independently of the DCS and ERI models; and (3) to discuss theoretical and empirical overlap and differences with previous models. The studies had to present associations between organisational justice and a mental health outcome, be prospective, and be entirely available in English or in French. Duplicated papers were excluded. Eleven prospective studies were selected for this review. They provide evidence that procedural justice and relational justice are associated with mental health. These associations remained significant even after controlling for the DCS and ERI models. There is a lack of prospective studies on distributive and informational justice. In conclusion, procedural and relational justice can be considered a different and complementary model to the DCS and ERI models. Future studies should evaluate the effect of change in exposure to organisational justice on employees' mental health over time.

TL;DR: This book by a teacher of statistics (as well as a consultant for "experimenters") is a comprehensive study of the philosophical background for the statistical design of experiment.
Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

TL;DR: In this paper, a model is tested in which burnout and engagement have different predictors and different possible consequences, showing that burnout is mainly predicted by job demands but also by lack of job resources, whereas engagement is exclusively predicted by available job resources.
Abstract: This study focuses on burnout and its positive antipode—engagement. A model is tested in which burnout and engagement have different predictors and different possible consequences. Structural equation modeling was used to simultaneously analyze data from four independent occupational samples (total N = 1698). Results confirm the hypothesized model indicating that: (1) burnout and engagement are negatively related, sharing between 10 per cent and 25 per cent of their variances; (2) burnout is mainly predicted by job demands but also by lack of job resources, whereas engagement is exclusively predicted by available job resources; (3) burnout is related to health problems as well as to turnover intention, whereas engagement is related only to the latter; (4) burnout mediates the relationship between job demands and health problems, whereas engagement mediates the relationship between job resources and turnover intention. The fact that burnout and engagement exhibit different patterns of possible causes and consequences implies that different intervention strategies should be used when burnout is to be reduced or engagement is to be enhanced.

TL;DR: The Multi-Ethnic Study of Atherosclerosis was initiated in July 2000 to investigate the prevalence, correlates, and progression of subclinical cardiovascular disease (CVD) in a population-based sample of 6,500 men and women aged 45-84 years for identification and characterization of CVD events.
Abstract: The Multi-Ethnic Study of Atherosclerosis was initiated in July 2000 to investigate the prevalence, correlates, and progression of subclinical cardiovascular disease (CVD) in a population-based sample of 6,500 men and women aged 45-84 years. The cohort will be selected from six US field centers. Approximately 38% of the cohort will be White, 28% African-American, 23% Hispanic, and 11% Asian (of Chinese descent). Baseline measurements will include measurement of coronary calcium using computed tomography; measurement of ventricular mass and function using cardiac magnetic resonance imaging; measurement of flow-mediated brachial artery endothelial vasodilation, carotid intimal-medial wall thickness, and distensibility of the carotid arteries using ultrasonography; measurement of peripheral vascular disease using ankle and brachial blood pressures; electrocardiography; and assessments of microalbuminuria, standard CVD risk factors, sociodemographic factors, life habits, and psychosocial factors. Blood samples will be assayed for putative biochemical risk factors and stored for use in nested case-control studies. DNA will be extracted and lymphocytes will be immortalized for genetic studies. Measurement of selected subclinical disease indicators and risk factors will be repeated for the study of progression over 7 years. Participants will be followed through 2008 for identification and characterization of CVD events, including acute myocardial infarction and other coronary heart disease, stroke, peripheral vascular disease, and congestive heart failure; therapeutic interventions for CVD; and mortality.
