- Most previous studies of burnout have focused on work environmental stressors, while familial factors so far mainly have been overlooked. The aim of the study was to estimate the relative importance of genetic influences on burnout (measured with Pines Burnout Measure) in a sample of monozygotic (MZ) and dizygotic (DZ) Swedish twins. The study sample consisted of 20,286 individuals, born 1959–1986 from the Swedish twin registry who participated in the cross-sectional study of twin adults: genes and environment. Probandwise concordance rates (the risk for one twin to be affected given that his/her twin partner is affected by burnout) and within pair correlations were calculated for MZ and DZ same—and opposite sexed twin pairs. Heritability coefficients i.e. the proportion of the total variance attributable to genetic factors were calculated using standard biometrical model fitting procedures. The results showed that genetic factors explained 33% of the individual differences in burnout symptoms in women and men. Environmental factors explained a substantial part of the variation as well and are thus important to address in rehabilitation and prevention efforts to combat burnout.

Journal article (peer-reviewed)abstract
- Within occupational health research, one of the most influential models is the Job Demands-Control-Support model. Numerous studies have applied the model to different domains, with both physical and psychological health outcomes, such as burnout. The twin design provides a unique and powerful research methodology for examining the effects of environmental risk factors on burnout while taking familial factors (genetic and shared environment) into account. The aim of the present study was to investigate the impact of familial factors on the associations of burnout with job demands, control and support. A total of 14 516 individuals from the Swedish Twin Registry, who were born between 1959 and 1986, and who participated in the Study of Twin Adults: Genes and Environment (STAGE) by responding to a web-based questionnaire in 2005, were included in the analyses. Of these, there were 5108 individuals in complete same-sex twin pairs. Co-twin control analyses were performed using linear mixed modeling, comparing between-pairs effects and within-pair effects, stratified also by zygosity and sex. The results indicate that familial factors are of importance in the association between support and burnout in both women and men, but not between job demands and burnout. There are also tendencies towards familial factors being involved in the association between control and burnout in men. These results offer increased understanding of the mechanisms involved in the associations between work stress and burnout.

- Reports an error in "Office type in relation to health, well-being, and job satisfaction among employees" by Christina Bodin Danielsson and Lennart Bodin (Environment and Behavior, 2008[Sep], Vol 40[5], 636-668). In the original article, a symbol was missing from Table 7 on p. 654. In that table, an open circle ("o") should have been present to show that the odds ratio indicated low risk for having poor quality of sleep among those who worked in the flex office. The corrected table is present in the erratum. (The following abstract of the original article appeared in record 2008-12036-003). This article investigates the hypothesis that office type has an influence on workers' health status and job satisfaction and 469 employees in seven different types, defined by their unique setup of architectural and functional features, have rated their health status and job satisfaction. Multivariate regression models were used for analysis of these outcomes, with adjustment for age, gender, job rank, and line of business. Both health status and job satisfaction differed between the seven office types. Lowest health status was found in medium-sized and small open plan offices. Best health was among employees in cell offices and flex offices. Workers in these types of offices and in shared room offices also rated the highest job satisfaction. Lowest job satisfaction was in combi offices, followed by medium-sized open plan offices. The differences between employees could possibly be ascribed to variations in architectural and functional features of the office types. (PsycINFO Database Record (c) 2016 APA, all rights reserved)

The relation between office type and workplace conflict : A gender and noise perspective
- 2015
-
In: Journal of Environmental Psychology. - : Elsevier BV. - 0272-4944 .- 1522-9610. ; 42, s. 161-171
-
Journal article (peer-reviewed)abstract
- This exploratory study aimed to investigate the impact of the office design on workplace conflicts, with a special attention to noise in the office. A gender perspective was applied. The sample consisted of 5229 employees from the Swedish Longitudinal Occupational Survey of Health 2010 (SLOSH), working in different office types. In the multivariate analysis office type was used as the explanatory variable with adjustments for age, supervisory position and labour market sector. Analysis stratified for gender was used. Among women a significant impact of office type per se on workplace conflicts was found, but not among men. For women several office types differed significantly from the cell-office with regard to prevalence of conflicts during the past two years, but for men only the combi-office differed from the cell-office. Noise had an impact on workplace conflicts, but is not the only explanatory factor since the effect of office type remained also after adjustment for noise in multivariate analyses. Other environmental factors inherent in the office type might thus explain the occurrence of conflicts.

Psychological factors related to health, back pain, and dysfunction
- 1994

Journal article (peer-reviewed)abstract
- Psychosocial variables may be important determinants of experienced back pain as well as dysfunction. This paper reports on differences on a battery of psychosocial variables between women, from the same work place, off work because of back pain, having only back pain (not off work), and those without back pain. The groups suffering pain had similar levels of pain intensity and frequency and the covariates of age and work load were used in MANCOVA analyses. The results showed significant overall differences on the Coping Strategies Questionnaire, Handicap Index, Duke Health Profile, as well as items concerning family support and the relation of pain to work. Several variables differed between the Healthy group on the one hand and the two groups suffering pain on the other hand. However, coping strategies and perceived health produced significant differences between all three groups in univariate analyses. Unlike other studies the Work APGAR produced no significant results. These data suggest that work status is not directly related to pain intensity, but rather to an interaction between psychosocial factors and the pain experience. Future research should delineate which variables may be used in screening.

Predicting grey-sided vole occurrence in northern Sweden at multiple spatial scales
- 2013
-
In: Ecology and Evolution. - Hoboken, USA : Wiley-Blackwell Publishing Inc.. - 2045-7758. ; 3:13, s. 4365-4376

Journal article (peer-reviewed)abstract
- Forestry is continually changing the habitats for many forest-dwelling species around the world. The grey-sided vole (Myodes rufocanus) has declined since the 1970s in forests of northern Sweden. Previous studies suggested that this might partly be caused by reduced focal forest patch size due to clear-cutting. Proximity and access to old pine forest and that microhabitats often contains stones have also been suggested previously but never been evaluated at multiple spatial scales. In a field study in 2010–2011 in northern Sweden, we investigated whether occurrence of grey-sided voles would be higher in (1) large focal patches of >60 years old forest, (2) in patches with high connectivity to sur- rounding patches, and (3) in patches in proximity to stone fields. We trapped animals in forest patches in two study areas (V€asterbotten and Norrbotten). At each trap station, we surveyed structural microhabitat characteristics. Land- scape-scale features were investigated using satellite-based forest data combined with geological maps. Unexpectedly, the vole was almost completely absent in Norrbotten. The trap sites in Norrbotten had a considerably lower amount of stone holes compared with sites with voles in V€asterbotten. We suggest this might help to explain the absence in Norrbotten. In V€asterbotten, the distance from forest patches with voles to stone fields was significantly shorter than from patches without voles. In addition, connectivity to surrounding patches and size of the focal forest patches was indeed related to the occurrence of grey-sided voles, with connectivity being the overall best predictor. Our results support previous findings on the importance of large forest patches, but also highlight the importance of connectivity for occurrence of grey-sided voles. The results further suggest that proximity to stone fields increase habitat quality of the forests for the vole and that the presence of stone fields enhances the voles’ ability to move between nearby forest patches through the matrix

Genetic and environmental influences on the association between performance-based self-esteem and exhaustion : A study of the self-worth notion of burnout
- 2016
-
In: Scandinavian Journal of Psychology. - : John Wiley & Sons. - 0036-5564 .- 1467-9450. ; 57:5, s. 419-426

Journal article (peer-reviewed)abstract
- In the self-worth model, burnout is considered to be a syndrome of performance-based self-esteem (PBSE) and experiences of exhaustion. Studies have shown that PBSE and burnout indices such as Pines' Burnout Measure (BM) are associated. Whether these variables have overlapping etiologies has however not been studied before. Genetic and environmental components of covariation between PBSE and exhaustion measured with Pines' BM were examined in a bivariate Cholesky model using data from 14,875 monozygotic and dizygotic Swedish twins. Fifty-two per cent of the phenotypic correlation (r = 0.41) between PBSE and Pines' BM was explained by genetics and 48% by environmental factors. The findings of the present study strengthen the assumption that PBSE should be considered in the burnout process as proposed by the self-worth conception of burnout. The present results extend our understanding of the link between this contingent self-esteem construct and exhaustion and provide additional information about the underlying mechanisms in terms of genetics and environment. This finding corroborates the assumed syndrome view on burnout, while it also suggests an altered view of how the syndrome emerges and how it can be alleviated.

Journal article (peer-reviewed)abstract
- OBJECTIVES: To investigate the impact of postoperative AF on late mortality and cause of death in CABG patients.DESIGN: All CABG patients without preoperative AF surgically treated between January 1, 1997 and June 30, 2000 were included (N = 1419). Altogether, 419 patients (29.5%) developed postoperative AF. After a median follow-up of 8.0 years, survival data were obtained, causes of death were compared and Cox proportional hazard analysis was used to determine predictors of late mortality.RESULTS: The total mortality was 140 deaths/419 patients (33.4%) in postoperative AF patients and 191 deaths/1 000 patients (19.1%) in patients without AF. Death due to cerebral ischemia (2.6% vs. 0.5%), myocardial infarction (7.4% vs. 3.0%), sudden death (2.6% vs. 0.9%), and heart failure (6.7% vs. 2.7%) was more common among postoperative AF patients. Postoperative AF was an age-independent risk indicator for late mortality with a hazard ratio (HR) of 1.56 (95% confidence interval 1.23-1.98).CONCLUSIONS: Postoperative AF is an age-independent risk factor for late mortality in CABG patients, explained by an increased risk of cardiovascular death.

Journal article (peer-reviewed)abstract
- OBJECTIVE: This article presents a study of postoperative atrial fibrillation (AF) and its long-term effects on mortality and heart rhythm.METHODS: The study cohort consisted of 571 patients with no history of AF who underwent primary aortocoronary bypass surgery from 1999 to 2000. Postoperative AF occurred in 165/571 patients (28.9%). After a median follow-up of 6 years, questionnaires were obtained from 91.6% of surviving patients and an electrocardiogram (ECG) from 88.6% of all patients. Data from hospitalisations due to arrhythmia or stroke during follow-up were analysed. The causes of death were obtained for deceased patients.RESULTS: In postoperative AF patients, 25.4% had atrial fibrillation at follow-up compared with 3.6% of patients with no AF at surgery (p<0.001). An episode of postoperative AF was the strongest independent risk factor for development of late AF, with an adjusted risk ratio of 8.31 (95% confidence interval (CI) 4.20-16.43). Mortality was 29.7% (49 deaths/165 patients) in the AF group and 14.8% (60 deaths/406 patients) in the non-AF group (p<0.001). Death due to cerebral ischaemia was more common in the postoperative AF group (4.2% vs 0.2%, p<0.001), as was death due to myocardial infarction (6.7% vs 3.0%, p=0.041). Postoperative AF was an age-independent risk factor for late mortality, with an adjusted hazard ratio of 1.57 (95% CI 1.05-2.34).CONCLUSIONS: Postoperative AF patients have an eightfold increased risk of developing AF in the future, and a doubled long-term cardiovascular mortality.

The transitional pattern of pain and disability, from perceived pain to sick leave : Experience from a longitudinal study
- 2013

Journal article (peer-reviewed)abstract
- Objectives: To investigate the prospective value of the transitional and dynamic patterns of pain disability over time on sick leave in chronic recurrent back/neck pain cases.Methods: The material used was based on a longitudinal study with three repeated measurements. The graded Chronic Pain Scale was used to assess levels of pain disability. The relationship between the transitional patterns of the pain disability score ( ten defined states of decrease, increase or no change, between two time points) and sick leave was analyzed for 909 chronic/recurrent cases in three different models using logistic regression. Results: Those with high level of pain disability have a more transitional pattern and their pain level changed during the time period studied. When adjusting for age, gender, education and previous sick leave, the final model indicated that the current level of pain disability was a risk factor in taking sick leave. The likelihood of sick leave was highest in the transition of pain into the highest levels of disability, independent of past disability level of pain. Earlier sick leave remained as an important predictor of sick leave.Conclusions: From a clinical and prognostic perspective the probability of sick leave will be different and can be predicted based on previous sick leave but not from former history of pain disability level or its transitional pattern.
