We found that the prevalence of job burnout, depression, and anxiety symptoms were high among managers. The managers in the district of high economic level and those ≤ 45 y had a higher score of job burnout, depression, and anxiety symptoms. The subjects with the educational level of junior college or below had a higher score of anxiety symptoms. We found a positive association between job burnout and both depression and anxiety symptoms, and a negative association between psychological capital and both depression and anxiety symptoms. Most importantly, we found a partial mediation role of psychological capital in the association between job burnout and depression symptoms among managers. These results provide us an opportunity to elucidate the complicated mechanism between job burnout and depression symptoms.
Our study found that the prevalence of depression and anxiety symptoms was high among managers, consistent with the previous report (19). The prevalence of depression symptoms in our study (18.5%) was almost the same as that in the Japanese public servants (18.8%), and the prevalence of anxiety symptoms in managers (14.3%) was somewhat lower than that of physicians in China (25.7%). Our findings showed that job burnout might explain the reason for the prevalence of depression and anxiety symptoms in managers in China. Hence, the government should develop a program for the delivery of mental health services for managers.
Our findings indicated that managers living in the district of low economic level had a higher score of job burnout, anxiety, and depression symptoms than other participants. The association between the economic level and depression was well established in the previous studies(20), with evidence that savings and homeownership might shape depression among low-income adults. The job burnout, depression, and anxiety symptoms might be higher among managers in the district of the low-income level due to factors such as income, unemployment, and financial distress. The rapid changes due to urbanization in the district of low-income level might also contribute to the increasing prevalence of stress-related diseases among managers. Additionally, the high prevalence of depression among managers in the district of low-income level could be explained by the psychological perceptions of environmental demands(21).
We found that the score of job burnout, depression, and anxiety differed in the managers of different ages, and younger workers always had the higher score of job burnout. Our findings concurred with the prior population-based study(22), which has demonstrated increased risks for depression among those with higher age. This might be explained by the fact that young managers do not adapt well to the new working environment, leading to the exhaustion of emotional resources and mental fatigue. Meanwhile, due to the lack of effective communication skills with the served subjects, new workers always encountered difficulties in dealing with interpersonal relationships(23). Another explanation was that new managers had high educational levels and high expectations for job prospects, however, they lacked practical work experiences. Therefore, they were more likely to feel frustrated, resulting in mental health problems such as anxiety and depression. In the contrast, old managers had more mature psychological resources, more working experiences, and more ways to deal with problems. Therefore, the prevalence of job burnout, anxiety, and depression symptoms were lower among the old managers compared to the younger ones.
We found that the score of anxiety symptoms was lower among the participants with a lower educational level compared with those with a higher educational level. People with a low educational level often adopted negative or temporary coping skills in the face of stress, and sometimes they chose to give up. However, the educational level of managers was highly correlated with age in our study, i.e., the managers with the older age had the higher educational level. Hence, we can conclude that managers with a higher educational level and younger ages had higher risks for anxiety symptoms.
Notably, we found that the psychological capital played a partial mediating role in depressive symptoms caused by job burnout, consistent with the previous report(24). The underlying mechanism was that the increase of job burnout led to the decrease of the stock of psychological capital, resulting in the lack of self-confidence, pessimism, and depression among managers. On the other hand, a previous study in China(25) demonstrated that the increase of psychological capital could help professional people deal with depressive symptoms more actively and more effectively. We should enhance the positive psychological resources of managers, and reduce the adverse effects due to job burnout and depression. Additionally, the mediating role of psychological capital is not significant in the association between job burnout and anxiety symptoms. The differences and underlying mechanisms should be well studied in the future.
Our study did have some advantages and disadvantages. We firstly demonstrated a partial mediating role of psychological capital in the association between job burnout and depression symptoms among managers in China. There were inevitably some disadvantages. Firstly, the cross-sectional design could not be beneficial to clarifying the causal relationship between job burnout, psychological capital, and mental symptoms. Secondly, the studying sample came from a population who underwent the routine psychological examination in a hospital, which might cause a selection bias. However, the studying hospital was the largest psychological specialized hospital. According to the demand of the local governments, almost all the managers in the studying area were included in the present study. That would be helpful to reduce the selection bias.
Conclusively, our findings highlight the role of psychological capital in the reduction of depression symptoms caused by job burnout. Intervention programs such as mindful self-compassion are beneficial for managers and should be provided in an effort to prevent mental problems among managers in China. Especially, this intervention would be cost-effective in reducing depression symptoms of managers. Future longitudinal studies may shed light on the mediating role of psychological capital between job stress, job burnout, and other mental problems.
