1. Introduction

Job burnout is also known as “job exhaustion”, “job abathy”, “job inertia”, “job indifference”, etc. [1]. American psychiatrist Freudenberger first proposed the word job burnout in 1974, which is used to describe the phenomenon of physical and emotional exhaustion experienced by people helping professionals in their work environment. Job burnout is a serious negative emotional state in which the service object of the industry individual falls into, and the incidence rate is high among nurses [2] [3] [4] [5]. With the progress of society, the requirements and standards of nurses are constantly improving, which often increases the professional pressure of nurses. Under the influence of these pressures, not only will reduce the enthusiasm of nurses, but also will increase the incidence of nurses’ job burnout [6]. According to relevant data reports: the incidence of job burnout of domestic nurses was 62.8%, among which 8.9% of nurses showed high burnout [7]. In this study, canonical correlation, multiple linear regression and path analysis were used to study the influencing factors of job burnout of nursing staff in tertiary hospitals in

2. Object and Method

2.1. Respondents

The method of multistage random sampling was used. The first stage: there are 5 Grade-A general hospitals in

2.2. Estimation of Sample Size

According to the pre-survey, the incidence of nurses’ willingness to postpone their retirement was 32.14% (18/56). According to the sample calculation formula of the current survey:

$N=\frac{{t}_{\alpha}^{2}P\left(1-P\right)}{{\delta}^{2}}$

With a = 0.05, P = 0.32, and allowable error & = 0.1P, the required sample size for calculation should be 850 persons. In order to ensure that there are enough samples for statistical analysis, the survey was expanded by 10%, and the sample size was finally determined to be 850 × (1 + 10%) = 935 people.

2.3. Method

2.3.1. Survey Tools

1) General information questionnaire: including age, gender, professional title, educational background, etc.

2) Nurse work stressor scale: the scale is divided into 5 aspects, with 35 items in total, 7 problems in nursing specialty and work, 5 problems in time distribution and workload [8], 3 problems in working environment and equipment shortage, 11 problems in patient care, and 9 problems in management and interpersonal relationship [9]. Grade 1 to 4 scoring method was used, including mild pressure (1 point), moderate pressure (2 points), considerable pressure (3 points), and maximum pressure (4 points). The higher the score, the greater the degree of stress [10].

3) Nurses’ job satisfaction scale: McCloskey/Mueller satisfaction scale, MMSs) is currently the most widely used and has been proved to have good reliability and validity, including 8 aspects of welfare, scheduling, balance between family and work, relationship between colleagues, social opportunities, opportunities to work part-time, job recognition, professional development and job control and responsibility, with a total of 31 items [11].

4) Nursing burnout scale (NBS): there are three dimensions of emotional exhaustion, depersonalization and less sense of achievement, with 15 items, and the score method of grade 1 to 4 is adopted. The total score of job burnout is the sum of all dimensions. According to Huang Xuefei’s job burnout analysis method [12], according to the score, it is divided into high, medium and low, 15 - 35 for low degree of job burnout, 36 - 55 for moderate job burnout, 56 - 75 for high job burnout.

2.3.2. Investigator Training and Pre-Investigation

The investigators have received unified training, unified guidance, mastered the investigation methods, strictly controlled the bias, and carried out the consistency test of the investigators. On November 2, 2015 and November 16, 2015, 56 nurses in a hospital were investigated to test the reliability and validity of the scale, and preliminary analysis was made to increase or decrease the influencing factors. The Cronbach coefficient reliability was 0.958, split half reliability was 0.824 and repeatability reliability was 0.924. The Cronbach coefficient reliability was 0.937, split half reliability was 0.789, and repeatability reliability was 0.914. The Cronbach coefficient reliability was 0.764, split half reliability was 0.750 and repetition reliability was 0.846. The reliability of the scale is high.

2.3.3. Data Collection

Through the coordination of the head nurse of the investigation department, the questionnaire was distributed, and the survey was completed according to the requirements, so as to ensure the authenticity and integrity of the questionnaire. It took about 20 minutes to complete by self filling. If more than 5 items are missing, they will be rejected. A total of 1100 questionnaires were sent out, and 1049 valid questionnaires were recovered, with an effective recovery rate of 93.36%.

2.4. Statistical Analysis

Epidata3.0 was used for double entry of data, and spss19.0 software was used for statistical analysis. ANOVA was used to compare the measurement data between the two groups. Canonical correlation analysis was used for multivariate correlation analysis, and multiple linear regression method was used for influencing factor screening. Amos17.0 software was used for path analysis. The inspection level was 0.05.

3.3. Canonical Correlation Analysis on the Dimensions of Job Burnout, Job Stressors and Satisfaction of Nurses

3.3.1. Canonical Correlation Analysis between Job Burnout and Job Stressors in Nurses

Based on the canonical correlation analysis of three dimensions of burnout scale and five dimensions of job stressor scale, it can be seen from Table 6 that there are three pairs of canonical correlation coefficients. The first canonical correlation coefficient is 0.4397 (F = 20.54, P < 0.0001), the contribution rate is 77.83%, the second canonical correlation coefficient is 0.2494 (F = 8.77, P < 0.0001), and the contribution rate is 21.53%.

According to Table 7, Table 8, the first pair of canonical correlation variables are

$\text{V1}=0.\text{1531x1}+0.\text{3468x2}-0.0\text{116x3}+0.\text{6127x4}+0.0\text{3}0\text{5x5}$

$\text{W1}=\text{1}.0\text{8}0\text{6y1}+0.\text{2673y2}-0.\text{4}0\text{38y3}$

Standardized canonical correlation variables showed that V1 was mainly affected by nursing problems, while W1 was mainly affected by emotional fatigue.

Table 7. Normalized V typical variable coefficients.

Table 8. Normalized w typical variable coefficients.

This shows that there is a close relationship between the nursing problems in the indicators of work stressors and emotional exhaustion in the indicators of job burnout.

The second pair of canonical correlation variables were

$\text{V2}=0.\text{3269x1}-0.\text{5776x2}+0.0\text{994x3}-0.\text{6414x4}+\text{1}.\text{1582x5}$

$\text{W2}=-0.\text{1}0\text{42y1}+0.\text{437}0\text{y2}+0.\text{86}0\text{1y3}$

Standardized canonical correlation variables showed that V2 was mainly affected by management and interpersonal problems, while W2 was mainly affected by depersonalization. This shows that there is a close relationship between the management and interpersonal problems in job stressors and depersonalization in job burnout indicators.

3.3.2. Canonical Correlation Analysis between Job Burnout and Job Satisfaction of Nurses

The canonical correlation analysis of three dimensions of job burnout scale and eight dimensions of job satisfaction scale showed that there were three pairs of canonical correlation coefficients. The first canonical correlation coefficient was 0.3791 (F = 12.8, P < 0.0001), the contribution rate was 55.58%, the second canonical correlation coefficient was 0.3374 (F = 9.7, P < 0.0001), and the contribution rate was 42.54% (Table 9).

According to Table 10, Table 11, the first pair of canonical correlation variables are

$\begin{array}{c}\text{V1}=0.\text{18}0\text{3cf1}-0.\text{3525cf2}-0.\text{2884cf3}+0.\text{4552cf4}-0.\text{3588cf5}\\ \text{\hspace{0.17em}}\text{\hspace{0.17em}}-0.\text{3196cf6}+0.\text{3161cf7}+0.\text{6764cf8}\end{array}$

$\text{W1}=-0.\text{3969y1}+0.\text{3685y2}+0.\text{9241y3}$

Table 9. Typical correlation coefficient between job burnout and job stressors.

Table 10. Normalized V typical variable coefficients.

Table 11. Normalized w typical variable coefficients.

Standardized canonical correlation variables showed that V1 was mainly affected by family and work balance, while W1 was mainly affected by depersonalization. This shows that there is a close relationship between the balance of sick family and work in job satisfaction index and depersonalization in job burnout index.

The second pair of canonical correlation variables were

$\begin{array}{c}\text{V2}=0.0\text{452cf1}+0.\text{1588cf2}+0.\text{168}0\text{cf3}+0.\text{1475cf4}+0.\text{1647cf5}\\ \text{\hspace{0.17em}}\text{\hspace{0.17em}}+0.\text{4642cf6}+0.0\text{475cf7}+0.\text{2248cf8}\end{array}$

$\text{W2}=-0.\text{8659y1}-0.\text{7279y2}+0.\text{3963y3}$

Standardized canonical correlation variables showed that V2 was mainly affected by job recognition, while W2 was mainly affected by emotional exhaustion. This shows that there is a close relationship between job recognition and emotional exhaustion in job burnout.

3.4. Analysis of Influencing Factors of Nurses’ Job Burnout

3.4.1. Multiple Linear Regression Analysis

Taking the total score of job burnout as y, the total score of job satisfaction, five dimensions of job stressors, employment status, personal pre tax income, professional title, position, medical trouble or medical violence at work, family property savings and property situation, Hospital: Set subvariables (Hospital 1, Hospital 2, Hospital 3); Departments: Set independent variables (Department 1, Department 2, Department 3, Department 4, Department 5, Department 6). The multiple linear regression analysis was conducted by the entry method and the step-by-step method. The factors entering the regression equation included hospital 1, hospital 2, hospital 3, department 3, management and interpersonal problems, professional title, total score of job satisfaction, and problems in patient care. The results are shown in Table 12.

Table 12. Multiple linear regression analysis of job burnout of nurses in grade three hospitals in Haikou City.

3.4.2. Path Analysis of Job Burnout among Nurses in the Top Three Hospitals in Haikou City

Based on the above factor analysis, combined with professional knowledge, take the total score of job burnout and the total score of job satisfaction as endogenous variables. Work stressor dimension 4 (management and interpersonal problems), work stressor dimension 5 (patient care Question), the job title is used as an exogenous variable, a path model is established, and the ML method is used to estimate the model parameters. According to the model correction index (MI), the final model is shown in Figure 1. All factors in the model are statistically significant. The model’s χ^{2} = 6.608, P = 0.086 > 0.05, CMIN/DF = 2.203 < 5, standard RMR = 0.0271, RSEMA = 0.034 <= 0.05, model fit is good, model fit index GFI = 0.997, adjusted fit index AGFI = 0.987; comparative fit index CFI = 0.996; standard fit index NFI = 0.993; value-added fit index IFI = 0.996, relative fit index RFI = 0.997, the above indicators are all greater than 0.9 and close to 1, indicating that the model fits well.

Combined with Figure 1 and Table 13, it can be seen that among the direct effects on job burnout, job stressor dimension 4 has the strongest effect, and its direct effect value is 0.219. The order of direct effects is job stressor dimension 4 (0.219), professional title (−0.112), job stressor dimension 5 (0.105), and total job satisfaction score (−0.097). The total effect of job stressor dimension 4 on job burnout was the strongest, with the total effect value of 0.245. The order of total effect was job stressor dimension 4 (0.245), job stressor dimension 5 (0.125), professional title (−0.112), and total score of job satisfaction (−0.097). The total score of job satisfaction and job title only play a direct role in job burnout, while job stressor dimension 5 and job stressor dimension 4 also play an indirect role in job burnout through the total score of job satisfaction.

4. Discussion

The results showed that the total score of nurses’ job burnout was 38.44 ± 7.55, high job burnout was 0.9%, moderate job burnout was 66.5%, low job burnout was 32.6%, which was different from Huang Xuefei’s. There are differences in the level of job burnout among different hospitals, which is consistent with the survey results of Wang Xia [13], which may be related to the size of the hospital and the number of patients. The larger the scale, the larger the number of patients, the higher the level of job burnout. The level of job burnout of nurses in different departments is different, which is consistent with the survey results of he Shuyun [14], which may be related to the number of patients accepted by different departments and the severity of patients’ illness. There are differences in job burnout among nurses with different professional titles, which is consistent with the survey results of Wu Dequan [15]. This may be related to the psychological endurance of nurses with different professional titles and the workload and responsibilities borne by individuals. The psychological bearing capacity of nurses is weak. The nurses and the Deputy chief nurses and above have undergone various professional training and have strong ability and psychological endurance. Professional titles not only encourage nurses to be positive, mobilize their enthusiasm, but also promote the improvement of nurses’ professional level and skills, which is an important influencing factor of job burnout. The level of job burnout among nurses of different ages is different, which is consistent with the survey results of Tao Xiuping [16]. The level of job burnout of nurses decreases with the increase of age, and the level of job burnout of young nurses is the highest. This may be related to the psychology of young nurses. Young nurses are different from older nurses, and they do not want to stay in the profession for a long time and are not sufficient Patience.

The results of canonical correlation model showed that the first canonical correlation coefficient was 0.4397, the second canonical correlation coefficient was 0.2494, V1 and W1 were mainly affected by nursing problems and emotional fatigue, V2 and W2 were mainly affected by management and interpersonal problems and depersonalization.

The results of canonical correlation model between job burnout and job satisfaction showed that the first canonical correlation coefficient was 0.3791, the second canonical correlation coefficient was 0.3374, V1 and W1 were mainly affected by the balance and depersonalization of family and work, V2 and W2 were mainly affected by job recognition and emotional fatigue, which showed that the balance between family and work was closely related to depersonalization, and positively correlated with work Recognition is closely related to emotional exhaustion and negatively correlated.

The results of path analysis showed that the factors influencing nurses’ job burnout were job stressor dimension 4, job stressor dimension 5, job title and job satisfaction. Job stressor dimension 4 and job stressor dimension 5 have positive effects on job burnout. First of all, the workload of nurses is very heavy. In addition to physical labor and mental labor, nurses have to carry out medical orders and face patients directly every day. However, managers and doctors are extremely busy with their work, and there is little communication with nurses. When problems arise, colleagues act on their own, and patients spend most of their time. There is a lack of time to communicate with each other, so it is difficult to become intimate friends. Secondly, nurses need to be patient and careful. They should be familiar with the use of various medical devices. Moreover, the social status of nursing work is very low. They often have to be called to and fro by patients. As soon as the patients have something to do, the nurses have to go to take care of them immediately. If it is too late, they will be held accountable by their family members. In today’s fierce Doctor-patient Conflict, how to deal with the patient's family members is also an issue For nurses’ job burnout is an important problem. It can be seen that job stressors are an important factor affecting the occurrence of job burnout of nurses, which is consistent with the research results of Yu Yanlin [17]. The total score of job satisfaction has a negative effect on job burnout. On the one hand, the welfare of nursing staff is very little, and the professional development opportunities are also very small. On the other hand, because of the particularity of the profession of nurses, it often means that their working hours are not stable. They often have to work shifts. For a period of time, they go to work in the daytime and at night. Moreover, most of the nurses are women. Staying up late is a very important problem for them. The family will also make a mess because of this inverted biological clock, especially for families with children The problem is, whenever there is a mistake or a problem, the nursing manager’s understanding and support for the nurse is not enough, and the work of the nurse is difficult to be recognized. The family members of the patient think that it is natural for the nurse to take good care of the patient, and there is no thanks. Once there is a mistake, it is the fault of the nurse. These will aggravate the degree of nurses’ job burnout. This is consistent with the investigation results of Ren Yaxin [18], Hua Qing [19], Lai Xiuhua [20].

5. Conclusion

Job stressors, job satisfaction and professional titles are the main factors that affect job burnout. More and more nurses are suffering from job burnout due to increasing pressure. The government and management units can take corresponding measures, such as improving the salary and welfare of nursing staff, organizing more activities, increasing the opportunity to communicate with colleagues, and communicating with other specialties (non Nursing). It is suggested that nursing managers should understand and support nurses, encourage them more, increase the opportunities to participate in nursing research, write and publish articles, improve the professional development opportunities of nursing profession, reasonably allocate working time, try to meet the needs of nurses, create a relaxed working environment and reduce the working pressure of nurses.
