Relationship Between Effort-Reward Imbalance, Over-Commitment and Occupational Burnout in the General Population: A Prospective Cohort Study.

Objectives: To prospectively investigate the association between Effort-Reward Imbalance (ERI) and over-commitment and the scores of the burnout dimensions over a 4 years follow-up period considering potential confounders. Methods: Data stemmed from CoLaus|PsyCoLaus, a population-based cohort study including 575 participants (mean age 55 years, 50% men). Participants completed the Maslach Burnout Inventory-General Survey, ERI and over-commitment questionnaires at baseline (T1) and after a 4 years follow-up (T2), and provided demographic, behavioral, psychiatric, personality and social support information through self-reported questionnaires and semi-structured interviews. Serially adjusted linear regression models were used. Results: ERI and over-commitment were not associated longitudinally with any of the burnout dimensions when controlling for confounders. One standard deviation increases in the scores of exhaustion, cynicism and professional efficacy were associated with one standard deviation increase in the scores of the same burnout dimensions longitudinally, and these associations were independent of the effects of ERI and over-commitment. Conclusion: Future studies should re-examine the effect of ERI and over-commitment on workers' burnout, considering the effects of confounders.

Organizational interventions and occupational burnout: a meta-analysis with focus on exhaustion.

PURPOSE: To assess whether organizational interventions are effective to prevent or reduce exhaustion, the core dimension of occupational burnout. METHODS: We searched in PubMed, EMBASE, PsycINFO, and Cochrane Library databases randomized and non-randomized controlled trials conducted among active workers and reporting the outcome as exhaustion score. We calculated the effect sizes using the pre-test-post-test control group design's estimate. We used the random effects model in meta-analysis and Cochrane collaboration's tool for interventions to assess the risk of bias. Overall quality of evidence was appraised using the GRADE. RESULTS: From the 2425 identified records, we assessed 228 full texts for eligibility and included 11 original articles describing 13 studies, 11 on organizational interventions, and 2 on combined inventions. The interventions were participatory (n = 9), focused on workload (n = 2), or on work schedule (n = 2). The overall effect size was - 0.30 ((95% CI = - 0.42; - 0.18), I2 = 62.28%), corresponding to a small reduction in exhaustion with a very low quality of evidence. Combined interventions had a larger effect (- 0.54 (95% CI = - 0.76; - 0.32)) than organizational interventions. When split by type of intervention, both participatory interventions and interventions focused on workload had a benefic effect of exhaustion reduction, with an estimated effect size of - 0.34 (95% CI = - 0.47; - 0.20) and - 0.44 (95% CI = - 0.68, - 0.20), respectively. CONCLUSION: Interventions at combined level in workplaces could be helpful in preventing exhaustion. However, the evidence is still limited, due to a high heterogeneity between studies, bias potential, and small number of eligible studies. This calls for further research, using workload interventions at organizational level, especially in sectors with high risk of job stress and exhaustion.

Determinants of Pesticide Exposure in Occupational Studies: A Meta-Analysis.

Few epidemiological studies use exposure determinants specifically tailored to assess pesticide or plant protection product (PPP) exposures when assessing presumed association between occupational exposure and health outcomes among agricultural workers. This lack of exposure specificity could lead to results that fail to detect an association. It could be related to the lack of consensus on exposure assessment methods and the choice of exposure determinants. We conducted a meta-analysis following the PRISMA checklist to identify PPP exposure determinants used in occupational studies and identified exposure determinants that best characterized agricultural exposures to PPPs. Out of 1436 studies identified, 71 were included. The exposure determinants identified were active ingredients, chemical classes, types of PPP, crops, tasks, frequencies, duration, lifetime exposure days, and intensity-weighted exposure days. Only six over 17 associations between exposure determinants and health outcomes were found with moderate quality of evidence. Overall, epidemiological studies had difficulty defining relevant determinants to characterize PPP exposures for agricultural workers. We recommend that a standardized list of determinants for PPP exposures in occupational exposure studies should include information on formulations, intensity, duration, and frequency of PPP exposure. Harmonized data collection on exposure and health outcomes are required as well as standard units for each exposure determinant.

Point prevalence of burnout in Switzerland: a systematic review and meta-analysis.

AIMS OF THE STUDY: To estimate the prevalence of occupational burnout among the Swiss working population. METHODS: We interrogated three international databases (Medline (PubMed), EMBASE, and PsycINFO) and the databases of 15 Swiss universities to identify studies reporting the prevalence of occupational burnout in Swiss workers over the last 10 years, before the COVID-19 pandemic. Data were summarised descriptively and quantitatively using random-effects meta-analysis. We investigated between-study heterogeneity by stratifying results according to the type of burnout measurement tool, by occupation and by cut-off values. Three outcomes were considered: clinical/severe burnout, overall burnout and emotional exhaustion. RESULTS: We identified 23 studies about workers in Switzerland and estimated the prevalence of clinical or severe burnout at 4% (95% confidence interval [CI] 2-6%). The average prevalence estimates for overall burnout and emotional exhaustion were similar at 18% (95% CI 12-25%) and 18% (95% CI 15-22%), respectively. When stratified by occupation, the clinical or severe burnout rates were higher among the healthcare workers than the general working population. CONCLUSIONS: These estimates of prepandemic (baseline) prevalence of occupational burnout are comparable with those available in the other countries where it is recognised and treated as a disease. They may prove useful in planning and assessing the effectiveness of interventions for prevention of occupational burnout and in minimising its negative consequences on individuals and on societies during and after the pandemic.

Holistic Assessment of Factors Associated with Exhaustion, the Main Symptom of Burnout: A Meta-Analysis of Longitudinal Studies.

BACKGROUND: This meta-analysis summarized longitudinal findings pertaining to exhaustion's predictors. In so doing, our aim was ultimately to identify target factors for the prevention of burnout. METHODS: We searched for studies that (a) examined predictors of exhaustion longitudinally and (b) reported correlation coefficients as an effect estimate. We conducted our literature search in three databases: MEDLINE, PsycINFO, and Embase. We focused on studies published between January 1990 and November 2020. Predictors were grouped into families, subfamilies, and subgroups. A meta-analysis of z-transformed correlation coefficients (rho) was performed. The results were scrutinized in relation to studies' follow-up length. RESULTS: We included 65 studies assessing 242 predictors of different types captured across different occupations. Our findings highlighted mostly weak associations (rho < 0.30). For six predictors-Job control, Job resources, Interactions at work, Communication and leadership, Job attitudes, and Work-family interface-longer length of follow-up involved weaker associations with exhaustion. The quality of the evidence available was generally low. CONCLUSIONS: The evidence available does not point to clear target factors for preventing burnout. The decrease in associations as the follow-up length increases may suggest a relatively short latency period, followed by recovery. Higher-quality cohorts should be conducted to better understand the etiology and course of burnout.

Determinants of Burnout among Teachers: A Systematic Review of Longitudinal Studies.

We aimed to review the determinants of burnout onset in teachers. The study was conducted according to the PROSPERO protocol CRD42018105901, with a focus on teachers. We performed a literature search from 1990 to 2021 in three databases: MEDLINE, PsycINFO, and Embase. We included longitudinal studies assessing burnout as a dependent variable, with a sample of at least 50 teachers. We summarized studies by the types of determinant and used the MEVORECH tool for a risk of bias assessment (RBA). The quantitative synthesis focused on emotional exhaustion. We standardized the reported regression coefficients and their standard errors and plotted them using R software to distinguish between detrimental and protective determinants. A qualitative analysis of the included studies (n = 33) identified 61 burnout determinants. The RBA showed that most studies had external and internal validity issues. Most studies implemented two waves (W) of data collection with 6-12 months between W1 and W2. Four types of determinants were summarized quantitatively, namely support, conflict, organizational context, and individual characteristics, based on six studies. This systematic review identified detrimental determinants of teacher exhaustion, including job satisfaction, work climate or pressure, teacher self-efficacy, neuroticism, perceived collective exhaustion, and classroom disruption. We recommend that authors consider using harmonized methods and protocols such as those developed in OMEGA-NET and other research consortia.

Psychometric validity of the Shirom-Melamed Burnout Measure and the Burnout Assessment Tool: a systematic review.

In the absence of internationally recognised standardised criteria, several patient-reported outcome measures (PROMs) have been developed to measure occupational burnout. The aim of this study was to extend our 2021 review of the psychometric validity of five PROMs to the Shirom-Melamed Burnout Measure (SMBM) and the Burnout Assessment Tool (BAT). To do that we ran a systematic literature search in the MEDLINE, PsycINFO, and Embase databases following our previous methodological framework and the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN). We assessed the level of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) guideline. We identified 694 publications on SMBM and 421 on BAT, but the final review includes eight papers on SMBM and three on BAT. Of the seven psychometric properties assessed for SMBM, content, structural, and criterion validity were rated as insufficient, whereas the quality of evidence for construct and internal consistency was high and moderate, respectively. Of the nine psychometric properties assessed for BAT, content, structural, criterion, and construct validity was moderate and internal consistency was high. One limitation of this study is that we did not assess cross-cultural validity, because the number of studies reviewed is too small and content validity can only be assessed based on the original PROM version rather than translation. To conclude, BAT is superior to SMBM in terms of psychometric validity, but the quality of evidence for some properties is low or very low, suggesting a need for additional validation studies.

Diagnostic Performances of an Occupational Burnout Detection Method Designed for Healthcare Professionals.

BACKGROUND: We aimed to assess the validity (criterion and cross-cultural validity) and reliability of the first occupational burnout (OB) detection tool designed for healthcare professionals in Belgium in the context of Swiss medical practice. METHODS: First, we assessed the sensitivity and specificity of the Tool. We developed this tool based on the consultation reports of 42 patients and compared its detection to the results of the Oldenburg Burnout Inventory (OLBI), filled-in by patients before a consultation. Second, we performed an inter-rater reliability (IRR) assessment on the OB symptoms and detection reached by the Tool between a psychiatrist, two psychologists, and an occupational physician. RESULTS: The Tool correctly identified over 80% of patients with OB, regardless of the cutoff value used for OLBI scores, reflecting its high sensitivity. Conversely, its specificity strongly varied depending on the OLBI cutoff. There was a slight to fair overall agreement between the four raters on the detection of OB and the number of OB symptoms. Around 41% of symptoms showed a substantial to an almost perfect agreement, and 36% showed a slight to a moderate agreement. CONCLUSIONS: The Tool seems useful for identifying OB of moderate and strong severity in both the Belgian and Swiss contexts.

Predictors of Occupational Burnout: A Systematic Review.

We aimed to review occupational burnout predictors, considering their type, effect size and role (protective versus harmful), and the overall evidence of their importance. MEDLINE, PsycINFO, and Embase were searched from January 1990 to August 2018 for longitudinal studies examining any predictor of occupational burnout among workers. We arranged predictors in four families and 13 subfamilies of homogenous constructs. The plots of z-scores per predictor type enabled graphical discrimination of the effects. The vote-counting and binomial test enabled discrimination of the effect direction. The size of the effect was estimated using Cohen's formula. The risk of bias and the overall evidence were assessed using the MEVORECH and GRADE methods, respectively. Eighty-five studies examining 261 predictors were included. We found a moderate quality of evidence for the harmful effects of the job demands subfamily (six predictors), and negative job attitudes, with effect sizes from small to medium. We also found a moderate quality of evidence for the protective effect of adaptive coping (small effect sizes) and leisure (small to medium effect sizes). Preventive interventions for occupational burnout might benefit from intervening on the established predictors regarding reducing job demands and negative job attitudes and promoting adaptive coping and leisure.

How to identify the most suitable questionnaires and rating scales for your clinical practice or research?

BACKGROUND: Selection of the most suitable instrument for a health outcome or exposure assessment is challenging, as there are many different instruments and their versions, most with unknown validity. AIMS: To develop guidelines facilitating the search for the most suitable instrument. MATERIALS AND METHODS: Based on our experience, we formalised a five-step process. The first step is the search for systematic reviews of available instruments validity in COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN), International prospective register of systematic reviews (PROSPERO), or conventional (eg, Medline and Web of Science) databases. If there is no systematic review, the clinician should look for original validation studies and assess them critically. We presented two alternatives of this assessment: qualitative using COSMIN and quantitative using our methodological framework. The latter helps to decide upon the instrument validity completeness and interpret the statistical results from original studies objectively. This process was then transformed into guidelines, which were tested by three external clinicians to select the most appropriate instrument to measure depression, occupational stress and daily fatigue. RESULTS: The guidelines were proved to facilitate the instrument search and selection, practical and time-saving. DISCUSSION: The guidelines assessment highlighted that clinicians should check whether the instrument that they are looking for was developed for screening or diagnosing purposes, whether it can be self-administered or not, and for which setting it was validated (academic vs clinical). CONCLUSION: These guidelines facilitate the objective choice of the most suitable instrument in clinical practice by making the search simple, systematic and time-effective.

Reference Ranges of 8-Isoprostane Concentrations in Exhaled Breath Condensate (EBC): A Systematic Review and Meta-Analysis.

Isoprostanes are physiopathologic mediators of oxidative stress, resulting in lipid peroxidation. 8-isoprostane seems particularly useful for measuring oxidative stress damage. However, no reference range values are available for 8-isoprosante in exhaled breath condensate (EBC) of healthy adults, enabling its meaningful interpretation as a biomarker. We conducted this systematic review and meta-analysis according to the protocol following PROSPERO (CRD42020146623). After searching and analyzing the literature, we included 86 studies. After their qualitative synthesis and risk of bias assessment, 52 studies were included in meta-analysis. The latter focused on studies using immunological analytical methods and investigated how the concentrations of 8-isoprostane differ based on gender. We found that gender had no significant effect in 8-isoprostane concentration. Among other studied factors, such as individual characteristics and factors related to EBC collection, only the device used for EBC collection significantly affected measured 8-isoprostane concentrations. However, adjustment for the factors related to EBC collection, yielded uncertainty whether this effect is due to the device itself or to the other factors. Given this uncertainty, we estimated the reference range values of 8-isoprostane stratified by gender and EBC collection device. A better standardization of EBC collection seems necessary; as well more studies using chemical analytical methods to extend this investigation.
