The relationship between anxiety and burnout:
The fact that anxiety leads to burnout has been widely verified[18]. Studies have reported that increased anxiety can be viewed as a predictive factor with regard to workplace burnout syndrome. Individuals suffering from anxiety are 2.4 times more likely to experience burnout than are nonanxious people [19]. Tan et al investigated burnout levels among 3,075 Singaporean healthcare workers and suggested that nurses obtained the highest mean burnout scores; furthermore, as their anxiety scores increased, burnout similarly increased[20]. The results of a cross-sectional survey of 784 nurses in China also revealed that anxiety is one of the factors influencing emotional exhaustion and depersonalization, which in turn lead to burnout[21]. This association reveals that the anxiety status of medical staff may directly impact their levels of burnout, thereby emphasizing the importance of paying attention to and actively managing anxiety and burnout among nurses. Previous studies have reported that individuals’ burnout is associated with anxiety; however, few studies have explored the internal mechanisms by which anxiety affects burnout. Further research on burnout and anxiety should thus be conducted.
The relationships between burnout and both coping and interpersonal relationships:
Moreover, personal coping styles have been reported to be significantly associated with burnout. Spaan et al. revealed that problem-focused coping can help staff mitigate the effects of burnout[22]. A cross-sectional study of 385 teachers revealed that effective coping strategies, such as problem solving, exercise and hobbies, improve emotional well-being, whereas negative coping methods lead to psychological distress and reduced work ethic [23]. This result is consistent with the findings reported Calegari JG et al., who indicated that negative coping decreases professional quality of life (including compassion satisfaction, burnout, and secondary traumatic stress), whereas positive coping improves such quality of life[24].
In addition, the adverse impacts of the workplace, which result in problems with interpersonal relationships, have been reported to be associated with increased burnout and lower professional fulfillment[25]. Generally, nurses' interpersonal relationships are categorized into interpersonal relationships among healthcare professionals and interpersonal relationships between nurses and their families. The results of a cross-sectional survey of 1,817 nurses in 228 nursing units revealed that the frequent exposure of staff to unsympathetic interpersonal relationships is strongly associated with separation[26]. The results of a study of physicians in Bangladesh also demonstrated that physicians who face potential interpersonal conflicts with colleagues or family members are more likely to experience burnout[27].
The potential mediating roles of coping strategies and interpersonal relationships in the association between burnout and anxiety among nurses:
Several studies have reported a link between anxiety and interpersonal relationships, and the relationship between anxiety and coping styles has also been verified[28, 29]. These studies have suggested that more positive coping styles are negatively associated with anxiety[30] and that interpersonal problems are associated with anxiety[31]. Therefore, it is reasonable to assume that anxiety can decrease a person's ability to solve problems, thus preventing individuals from adopting more positive coping styles; furthermore, as anxiety levels increase, such individuals abandon assertive and optimistic approaches in favor of helplessness/self-blame and conformity[32]. In addition, anxiety reduces the quality of an individual's interactions with others, thus leading to strained or distant relationships.
Prolonged exposure to this situation can cause an individual's psychological resources to be steadily depleted, which may ultimately lead to burnout.
However, a significant amount of research has explored the associations among anxiety, interpersonal problems and positive coping with burnout. However, few studies have explored the roles of positive coping and interpersonal problems in the relationship between anxiety and burnout.
The stress and coping model was proposed by Lazarus. He claimed that the stress responses caused by specific stressors are mediated by two important psychological processes, namely, cognitive evaluation and coping. Stress responses occur when the stressor stimulus exceeds an individual's coping capacity and perceived resources[33]. Therefore, this study aimed to investigate the levels of burnout exhibited by Chinese nurses and to explore the relevant factors that lead to burnout among nurses. Moreover, a stress and coping model was used to guide the present research. Anxiety has been viewed as a source of stress, and burnout has been viewed as a stress response. Interpersonal relationships and positive coping mediate this process. The following hypotheses were proposed in this study:
H1: Anxiety directly affects burnout.
H2: Interpersonal relationships mediate the relationship between anxiety and burnout.
H3: Positive coping mediates the relationship between anxiety and burnout.
The conceptual model of this study is shown in Fig. 1.
The relationships between burnout and other demographic factors:
In addition, many studies have indicated that burnout among nurses is caused by several factors, such as monthly income[34]. A meta-analytic study of nurses indicated that age is also a significant predictor of burnout[35]. Gender has also been shown to be related to burnout; specifically, male nurses are more likely to experience burnout[36]. Excessive education and training are also associated with burnout among healthcare workers[6]. In addition, certain studies have reported that the work environment is an important factor with regard to burnout among nurses[37]; for example, departments such as obstetrics, pediatrics, and emergency medicine have been identified as important environmental factors pertaining to burnout among nurses[38–40].
However, research on the demographic factors that contributes to burnout remains insufficient. For example, previous studies have investigated mostly the effects of night shift length and frequency on burnout, but the specific number of night shifts that are most likely to lead to burnout requires further exploration[41]. In addition, the results of studies on the impact of increased levels of education on burnout have been controversial[42–44]. Therefore, the purpose of this study was to explore the demographic factors that predict burnout among nurses. The following hypothesis is thus proposed:
H4: Some demographic factors predict burnout among nurses.
