Work-based predictors of mortality: A 20-year follow-up of healthy employees.

Objectives: This study investigated the effects of the Job-Demand-Control-Support (JDC-S) model's components, workload, control, peer and supervisor social support, on the risk of all-cause mortality. Also examined was the expectation that the above work-based components interact in predicting all-cause mortality. The study's hypotheses were tested after controlling for physiological variables and health behaviors known to be risk factors for mortality. Main Outcome Measure: The design used was prospective. Baseline data were obtained from healthy employees (N = 820) who underwent periodic health examinations in 1988. Follow-up data on all-cause mortality were obtained from the participants' computerized medical file, kept by their HMO, in 2008. The baseline data covered socioeconomic, behavioral, and biological risk factors in addition to the components of the JDC-S model. During the period of follow-up, 53 deaths were recorded. Data were analyzed using Cox regressions. Results: Only one main effect was found: the risk of mortality was significantly lower for those reporting high levels of peer social support. The study found two significant interactions. Higher levels of control reduced the risk of mortality for the men and increased it for the women. The main effect of peer social support on mortality risk was significantly higher for those whose baseline age ranged from 38 to 43 but not for the older than 43 or the younger than 38 participants. Conclusion: Peer social support is a protective factor, reducing the risk of mortality, while perceived control reduces the risk of mortality among men but increases it among women.

The mediating effects of job satisfaction and propensity to leave on role stress-job performance relationships: Combining meta-analysis and structural equation modeling.

This article combines meta-analysis with structural equation modeling to compare alternative models of the relationships among work stress, psychological mediators, and job performance. Specifically, the authors examined the mediating effects of job satisfaction and propensity to leave and their effect on the relationships between role ambiguity, role conflict, and job performance. The meta-analysis included both published and unpublished studies conducted over a period of 25 years, resulting in 113 independent samples with more than 22,000 individuals. As hypothesized, the structural model that best fit the meta-analytic estimates was the partial mediation model, in which stress is related to job performance both directly and indirectly through job satisfaction and propensity to leave and in which all path coefficients were reliably different from zero. The results are discussed in terms of theoretical contributions and implications for future stress-performance research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A prospective study of the association between obesity and burnout among apparently healthy men and women.

The authors prospectively tested the hypothesis that obesity predicts burnout and the reverse-causation hypothesis that burnout predicts obesity. Respondents were 724 men and 340 women, apparently healthy employees, who underwent routine periodic health examinations at 2 points of time about 18 months apart. Obesity was assessed by body mass index, waist-hip ratio, and waist circumference. In regression analyses, done separately for men and women, the authors controlled for depressive symptomatology, sport activity, and Time 1 levels of the criterion. The hypothesis that burnout predicts obesity was not supported. The authors found that Time 1 measures of obesity predicted reductions rather than the hypothesized elevations of Time 2 burnout levels. The authors also found that for male respondents with relatively higher levels of Time 1 burnout, the higher their level of Time 1 obesity measure, the lower their level of T2 burnout.

The Association Between Burnout, Depression, Anxiety, and Inflammation Biomarkers: C-Reactive Protein and Fibrinogen in Men and Women.

Following the demonstrated association of employee burnout or vital exhaustion with several risk factors for cardiovascular disease (CVD) and CVD risk, the authors investigated the possibility that one of the mechanisms linking burnout with CVD morbidity is microinflammation, gauged in this study by high-sensitivity C-reactive protein (hs-CRP) and fibrinogen concentrations. Their sample included 630 women and 933 men, all apparently healthy, who underwent periodic health examinations. The authors controlled for possible confounders including 2 other negative affective states: depression and anxiety. In women, burnout was positively associated with hs-CRP and fibrinogen concentrations, and anxiety was negatively associated with them. In men, depression was positively associated with hs-CRP and fibrinogen concentrations, but not with burnout or anxiety. Thus, burnout, depression, and anxiety are differentially associated with microinflammation biomarkers, dependent on gender. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Teachers’ stressors and strains: A longitudinal study of their relationships.

[Correction Notice: An erratum for this article was reported in Vol 17(1) of International Journal of Stress Management (see record 2010-02418-002). In the article, “Teachers’ Stressors and Strains: A Longitudinal Study of Their Relationships” by Arie Shirom, Amalya Oliver, and Esther Stein (International Journal of Stress Management, 2009, Vol. 16, No. 4, pp. 312-332), the two co-authors’ affiliations were incorrectly listed. The co-authors’ correct affiliations are as follows: Amalya Oliver, Hebrew University of Jerusalem and Esther Stein, Beit Berl Educational College.] The authors tested the hypothesized unidirectional or bidirectional effects of 5 types of teachers’ work-related stressors on each of the 4 types of psychological strain: somatic complaints, burnout, and intrinsic and extrinsic job dissatisfaction. The authors used structural regression analyses to analyze the responses of a representative sample of 404 high school teachers who had completed both our T1 (beginning of school year) and T2 (end of school year) questionnaires. The authors found support for the expected unidirectional effects of the T1 work-related stressors on the respondents’ T2 somatic complaints (with baseline somatic complaints controlled for), and also for the expected unidirectional effects of T1 intrinsic and extrinsic job dissatisfaction on the T2 values of the five types of stressors (with baseline stressors controlled for). Only partial support was found for the expected bidirectional relationships between the stressors and teachers’ burnout. The authors suggest that the directionality across time of the relationships between stressors and strains may depend on the intrinsic properties of the strain under consideration.

Strike characteristics as determinants of strike settlements: A chief negotiator's viewpoint.

Management perceptions of advantageous settlements of strikes were predicted by the extent to which the struck plant was kept in operation, the extent to which a mediator was involved, frequency of strikes in the plant in the past, duration of the strike and its breadth. Data from 51 chief management negotiators show that past frequency, duration, and a mediator's involvement were not significant as predictors. The management's perception of strike settlement as advantageous was found to be positively affected either by large breadth of the strike or by the management's success in keeping the plant in operation during the strike. Results indicate that management's power to resist strikes by operating the struck plant is a significant predictor. Findings cast doubt on the notion that unions are successful in identifying as strike targets employers who are vulnerable to the costs imposed by a strike.

Photoionization of Ferrocyanide at Various Wavelengths in Polar Glasses at 77°K

Solutions of potassium ferrocyanide in 10 N NaOH glass and in ethylene-glycol/water (3/1) glass at 77°K were irradiated with UV-light. The ratio of the yields of radicals in the two solvents, as well as the scavenging efficiency of an election scavenger (acrylamide) in 10 N NaOH, were found to change with the irradiation wavelength. From the experiments the conclusion is drawn that the ejection of electrons may occur from different electronic levels depending on the excitation wavelength and that the electrons ejected from a charge-transfer-to-solvent state have higher reactivity with a scavenger than electrons ejected from intramolecular singlet states.     

A comparison of the construct validity of two burnout measures in two groups of professionals.

The authors studied certain aspects of the construct validity of the Maslach Burnout Inventory-General Survey (MBI-GS), the most popular measure of burnout, and that of the Shirom-Melamed Burnout Measure (SMBM). These burnout measures were compared with respect to their psychometric characteristics and factorial validity in two groups of professionals, human service and other professionals (N=196 and 226, respectively), who completed questionnaires at work. As hypothesized, the confirmatory factor analyses supported a two-factor and a three-factor structure invariance across the two groups considered for the SMBM and the MBI-GS, respectively, with superior fit found for the SMBM.
