Background: Chronic exposure to occupational stress may lead to negative health consequences. Creating less stressful work environments and making employees physically and psychologically more resilient against stress are therefore two major public health concerns. This study examined whether cardiorespiratory fitness moderated the association between occupational stress, cardiovascular risk, and mental health. Methods: Stress was assessed via the Effort-Reward Imbalance and Job Demand-Control models in 201 police officers (36% women, Mage = 38.6 years). Higher levels of blood pressure, blood lipids, blood sugar, and unfavorable body composition were considered as cardiovascular risk factors. Burnout, insomnia and overall psychological distress were used as mental health indicators. Cardiorespiratory fitness was assessed with a submaximal bicycle test. Results: High cardiorespiratory fitness levels were associated with a reduced cardiometabolic risk, whereas high stress levels were associated with better mental health. Among participants who perceived a high Effort-Reward Imbalance, those with high fitness levels showed lower overall cardiovascular risk scores than their colleagues with low fitness levels. Conclusions: Work health programs for police officers should consider the early screening of burnout, sleep disturbances, and overall mental wellbeing. To increase cardiovascular health, including fitness tests in routine health checks and promoting physical activity to further increase cardiorespiratory fitness appears worthwhile.

Researchers have emphasized the role of physical activity in accelerating recovery from stress. Therefore, the primary goal of the present study was to examine whether regular physical activity moderates the relationship between occupational stress and burnout symptoms in Swiss workers. 309 employees took part in the cross-sectional study. Occupational stress was operationalized with the job demands–control model and the effort–reward imbalance model. Physical activity was assessed via the International Physical Activity Questionnaire; burnout symptoms were measured with the Shirom–Melamed Burnout Measure. Higher occupational stress was positively associated with burnout symptoms, whereas higher physical activity levels were negatively associated with occupational stress and burnout symptoms. Participants with higher physical activity levels reported fewer burnout symptoms when they perceived high stress levels, independent of whether occupational stress was assessed via the job demands–control or effort–reward imbalance model. Although job constraints are seldom modifiable, we claim that regular leisure-time physical activity is more than a simple pastime and can make an important contribution to a thriving workforce that feels better able to cope with occupational stress.

BackgroundBurnout has long been understood as work-related physical, emotional, and cognitive exhaustion. However, burnout symptoms can also be found among younger people, including school-aged adolescents. While the Shirom-Melamed Burnout Measure (SMBM) is a widely applied instrument, its psychometric properties have not yet been investigated in adolescent populations. We therefore examined the psychometric properties of the SMBM in three independent samples of adolescents.MethodsIn total, 249 high school students, 144 vocational students, and 257 adolescent elite athletes completed the SMBM, along with questionnaires related to perceived stress, depressive symptoms, and life satisfaction. Descriptive statistics, gender differences, and internal consistency, convergent/discriminant validity, and factorial validity (including measurement invariance across genders) were examined in each sample.ResultsThe SMBM had adequate internal consistency. Confirmatory factor analyses showed that both a first- and second-order model achieve good model fit. Moreover, evidence for sufficient convergent and discriminant validity was found. Finally, in two of the three samples, female adolescents reported higher SMBM scores.ConclusionsThe SMBM has been widely used in international burnout research. However, this is the first study providing empirical evidence that the SMBM has acceptable psychometric properties and satisfactory convergent/discriminant and factorial validity among young people. The SMBM is a concise and economic tool to assess self-rated symptoms of burnout, and presents a valuable alternative to existing school burnout inventories. In particular, the SMBM can facilitate the investigation of the transition of young people from school to working life.Electronic supplementary materialThe online version of this article (10.1186/s12888-018-1841-5) contains supplementary material, which is available to authorized users.

Burnout is considered an occupation-related psychological syndrome consisting of emotional, physical, and cognitive exhaustion. To assess dimensions of burnout, the Shirom–Melamed Burnout Measure (SMB M ) is widely used, but its validity and reliability have rarely been examined in adult samples. The aim of this study is to examine the psychometric properties of the German version of the SMB M in two independent samples of adults. In total, 311 adult workers and 201 police officers completed the SMB M , and questionnaires related to perceived stress and mental well-being. Descriptive statistics, internal consistency, convergent validity, and factorial validity were assessed for both samples, separately for male and female participants. The German SMB M had adequate psychometric properties and sufficient convergent validity. In confirmatory factor analyses, we found a good fit for both the first- and second-order model. Furthermore, measurement invariance across gender was observed in both samples. Although the SMB M is a popular instrument among burnout researchers, this study demonstrates for the first time that the SMB M can be considered a valid and reliable tool to assess burnout symptoms in both male and female adults and across different professional groups. Furthermore, with its 14 items, the SMB M is a succinct and economic self-assessment tool for symptoms of burnout.
