Research on Job Satisfaction and Inuencing Factors of Scientic Researchers in S Hospital of Guizhou Province

Objective: To analyze the job satisfaction of hospital researchers and its inuencing factors. Methods: A questionnaire survey was conducted to investigate the job satisfaction of 276 researchers in S Hospital of Guizhou Province from May to July of 2020. Independent sample T test and one-way variance were used to analyze the satisfaction of researchers with demographic characteristics. Multiple linear regression analysis was used to analyze the factors affecting the satisfaction of researchers. Results: The average score of the hospital researchers' overall job satisfaction was 3.64±0.42, which was at the satisfaction level. The six dimensions, including self-ecacy, scientic research system and salary and welfare, were signicantly positively correlated with overall satisfaction (r>0.4).The differences in overall satisfaction of different ages were statistically signicant (P=0.013<0.05).The linear regression analysis found that all the six dimensions had a signicant positive impact on the overall job satisfaction, of which the scientic research system had the most signicant impact. Conclusion: We can improve the hospital scientic research level by improving the salary and welfare level of scientic research staff, changing the scientic research management concept, establishing and perfecting the scientic research management system, and taking targeted measures for the researchers with low satisfaction.


Introduction
The level of hospital scienti c research affects the comprehensive strength of the hospital, represents the competitiveness of the hospital in the medical eld, and also determines the innovation ability of the hospital. With the competition of large-scale public hospitals gradually turning from extensive scale expansion to ne management and key discipline construction, the scienti c research construction and management in "medical technology, science, education and research" also become important support for "key disciplines, superior talents, resource aggregation and achievement transformation" [1]. Therefore, it is highly concerned by hospital leaders and research managers to create a good scienti c research atmosphere, stimulate the enthusiasm of medical staff for scienti c research and promote the better development of scienti c research. In practical work, Hospital researchers have a special dual identity.
They are not only the main body of medical work, but also the main body of scienti c research. They should not only deal with the busy business work, deal with the complex doctor-patient relationship, but also complete the very important scienti c research tasks [2][3]. Especially in large general hospitals, scienti c research achievements are closely related to the promotion of professional titles [4]. Multiple pressure has become the main contradiction that affects hospital researchers to engage in scienti c research. Therefore, it is necessary to measure the satisfaction of hospital researchers so as to have a timely and in-depth understanding of the working conditions of hospital researchers.
According to the current scholars of the existing research results, the researchers satisfaction in uenced by many factors, such as JiWeiPing, PuJiang etc. [2] in the hospital scienti c research management based on the employee satisfaction survey in the study found that men and women hospital scienti c research personnel's job satisfaction in the gender group there was no statistically signi cant difference when comparing satisfaction score, and in the medical sequence and auxiliary departments, junior, middle and senior titles satisfaction to compare the difference was statistically signi cant. Zhang Yingyuan, Chen Zhuo et al. [5] conducted a research satisfaction survey on the professional and technical personnel of Beijing Maternity Hospital, so as to understand and analyze the differences in the scienti c research satisfaction of different types of professional and technical personnel and explore the factors affecting the satisfaction. The results show that the researchers' satisfaction with the research of the institute is between "relatively satis ed" and "average", and it is also found that the research satisfaction is in uenced by both subjective feelings and objective environment. Zhang Huifang, Miao Miao et al. [6] conducted a survey on the satisfaction of scienti c researchers in a tertiary hospital from the perspective of scienti c research incentive. It was found that in terms of the degree of respect is lower, the higher the degree of staff satisfaction in scienti c research, transformation and scienti c researchers' awareness to protect the satisfaction of the minimum senior titles, and in terms of different job categories, engaged in clinical and basic researchers research the lowest satisfaction. Through literature review, it is found that at present, most studies on the job satisfaction of hospital staff are done by clinical workers or nursing staff, and there is a lack of attention to hospital researchers. Therefore, this paper takes the hospital scienti c research personnel as the research object, carries out the job satisfaction survey, and discusses the in uencing factors of the group satisfaction, so as to provide the practical basis for the leaders to think about how to improve the satisfaction of the scienti c research personnel and stimulate the scienti c research vitality of the medical staff, and also provides a reference for the hospital to formulate more reasonable and applicable policies and stimulate the enthusiasm of medical staff in scienti c research.

Objects
The inclusion criteria of the respondents are as follows: rst, presiding over or participating in scienti c research projects as a main member of the project team; Second, he has published more than one research paper in Chinese science and technology core journals or above. Third, all the respondents are formal staff of the hospital [2]. A questionnaire survey was conducted to investigate the job satisfaction of researchers in S Hospital of Guizhou Province who met the above three standards. A total of 276 questionnaires were collected in this survey, 39 of which were invalid and 237 of which were valid, with an effective recovery rate of 86%.

Questionnaire setup
Satisfaction is the psychological and physiological feeling of employees [7],with strong subjectivity. Besides, the cognition of different individuals will be affected by individual experience, self-interest and other factors, so it is necessary to study from different angles and using various ways and methods [8][9][10].Therefore, the Spector job satisfaction survey scale [11] was used in this study to design a questionnaire for medical staff's scienti c research satisfaction in combination with relevant domestic scales [12].The survey included basic information (gender, age, education level, etc.) of the hospital researchers. Job satisfaction, this part is divided into two scales: the job itself and the working relationship, which contain 26 indicators. In the part of job satisfaction, a ve-point likert scale was used.
The answers were set as "very disagree", "disagree", "general", "agree" and "very agree", and the scores were recorded as 1-5 points in turn. The average satisfaction of 1-2 points is de ned as "dissatisfaction", 2-3 points is de ned as "general", 3-4 points is de ned as "satis ed", 4-5 points is de ned as "very satis ed".

Quality Control
In order to ensure the scienti city and effectiveness of the research, the research group did a pre survey on the questionnaire, and tested its reliability and validity. After several revisions, the nal version was con rmed. In order to ensure the quality of data, the parallel double entry method was adopted to enter all data information and establish a database. The reliability test results of the formal questionnaire showed that the Cronbachs' coe cients [13] of the total questionnaire and the two subscales were both greater than 0.8, indicating that the questionnaire had strong reliability. Exploratory factor analysis was used to detect the validity of the scale. The analysis results showed that the KMO value of the scale was 0.881, and the Bartlett spherical test c 2 was 3352.990. The corresponding signi cance level was P<0.001, which was suitable for factor analysis and also indicated that the validity of the questionnaire was relatively high.

Statistical methods
EPiData3.1 was used to establish a database, and after data cleaning, SPSS24.0 was used for statistical analysis. Measurement data are expressed as x̄ ± s. Independent sample T test and one-way variance were used to analyze the satisfaction difference of researchers with different demographic characteristics. Multiple linear regression was used to analyze the factors affecting the satisfaction of hospital researchers, and the difference of P<0.05 was statistically signi cant.

Sample description
A total of 237 valid questionnaires were collected, and the effective recovery rate was 86%. Among the 237 researchers, 95 were male (40.1%), 142 were female (59.9%); the respondents were 30-39 years old, accounting for 57.0%; 87.8% of the respondents were married; 57.4% of the respondents had master's degree; 90.3% had master's degree and doctor's degree; 30.4% had worked for 6-10 years; 40.9% of the respondents had intermediate professional titles; the respondents were scienti c researchers 60.3% of the posts were clinicians, as shown in Table 1. The principal component extraction method and the maximum variance method were used for orthogonal rotation, and the common factor was extracted with the principle of eigenvalue greater than 1 [14]. Four components were extracted from the "Work itself" scale and two from the "working relationship" scale. The variance interpretation rates of each component in the two large tables were 14.998%, 12.033%, 10.198%, 9.837%, 9.499% and 7.913%, respectively. The cumulative variance contribution rate of the six components was 64.477%. By referring to relevant literature and the meaning re ected by each item in each component, the scale of "work itself" was divided into four dimensions: scienti c research system, scienti c research management, self-e cacy, salary and welfare, and the scale of "working relationship" was divided into two dimensions: leadership factor and colleague relationship [15].

Descriptive statistics
The analysis results showed that the average score of overall satisfaction of hospital researchers was 3.64 ± 0.42, which was at the satisfaction level. The average scores of the other six dimensions, from high to low, were self-e cacy, scienti c research management, scienti c research system, colleague relationship, leadership factors, and salary and welfare, as shown in Table 2.Pearson correlation analysis was used to study the correlation between each dimension of researchers' satisfaction and the overall satisfaction, and the results showed that the correlation coe cient "r" between each dimension and the overall satisfaction was greater than 0.4,indicating that there was a signi cant positive correlation between each dimension and the overall satisfaction (P < 0.001),and each dimension has a certain in uence on the overall satisfaction effect, with the scholar S Kim, SM Park claims (employees' job satisfaction were the major in uencing factors of the job itself,boss,pay,promotion,working environment and colleague) similar[16]. The results of one-way ANOVA showed that the mean satisfaction of researchers aged 29 and below, 30-39, 40-49, 50 and above were 3.76, 3.76, 4.00 and 3.84 respectively, F = 2.889, P = 0.036. According to the above age groups, the mean of the overall satisfaction of researchers is 3.64, 3.58, 3.79 and 3.57, respectively. In terms of overall satisfaction,F = 3.662, P = 0.013, which shows that there are signi cant differences between different ages in terms of scienti c research management and overall satisfaction.
The results of one-way ANOVA for different ages, education, working years, professional titles and job categories also showed that these demographic variables had statistically signi cant differences in salary and welfare (P < 0.05). Speci cally, there were signi cant differences in the satisfaction of researchers at different ages. The satisfaction of researchers aged 40-49 was the highest, followed by  Table 3 for details.

Multiple linear regression analysis
For the further study of scienti c research personnel's overall job satisfaction of each dimension, ruled out the mixed interference of the age, with self-e cacy (X1), the scienti c research management (X2), scienti c research system (X3), salary welfare (X4), leading factors (X5) and colleague factors (x6) were taken as independent variables, with the average scores of the overall satisfaction (Y) as the dependent variable linear regression analysis. Results showed that six dimensions were signi cantly positive in uence on overall satisfaction (beta > 0, P < 0.05), the in uence degree of each dimension for the overall satisfaction from high to low in turn is the scienti c research system (beta = 0.283), the scienti c research management (beta = 0.272), and self-e cacy (beta = 0.244), leading factor (beta = 0.223), salary welfare (beta = 0.219), the relationship between the colleague (beta = 0.216), see Table 4.Based on the above analysis results, the following regression equation can be obtained: Overall  According to the data analysis, the overall job satisfaction score of researchers in S Hospital is 3.64, which is between 3-4, reaching the satisfaction level. Through factor analysis, it is found that the job satisfaction of researchers in S Hospital is composed of six dimensions: self-e cacy, scienti c research system, scienti c research management, salary and welfare, leadership factors and colleague relationship. The average score of satisfaction of the six dimensions is between 3.42 and 3.85, which indicates that the researchers in S hospital have a high job satisfaction.

Analysis of in uencing factors on job satisfaction of Hospital researchers
The salary and welfare is one of the factors that affect the job satisfaction of hospital researchers. The Pearson correlation analysis shows that the correlation coe cient between salary and welfare and overall job satisfaction reaches 0.6, which indicates that salary and welfare have a signi cant positive impact on overall job satisfaction. This is consistent with the results of Cabelkova I [17][18][19][20]et al. The difference analysis found that different ages, education, working years, professional titles and job categories all had statistically signi cant differences in salary and welfare satisfaction, and the above research results all indicated that salary and welfare had an impact on the job satisfaction of hospital researchers.
The results of data analysis show that compared with the ve dimensions of self-e cacy and scienti c research system, the satisfaction degree of salary and welfare is the lowest (3.42 ± 0.57), and the difference analysis shows that the researchers with low education background, professional title and short working years have the lowest satisfaction on salary and welfare. According to Maslow's hierarchy of needs theory [21], salary and welfare are the necessary conditions to realize their basic needs. When the basic needs cannot be met, the satisfaction can not be improved, and the enthusiasm and e ciency of scienti c research work are di cult to improve.
The scienti c research system has the greatest in uence on the hospital researchers' work satisfaction. The results of multiple linear regression analysis show that when six dimensions are taken as independent variables and overall job satisfaction is taken as dependent variables, the tting degree reaches 99.1%, which indicates that the explanatory power of each variable is very high and that each dimension has a certain degree of in uence on overall satisfaction. According to the standardized coe cient, the research system has the greatest impact on the job satisfaction of researchers. Scienti c research system mainly includes relevant systems of promotion, professional title evaluation and appointment, performance assessment and other aspects of hospital scienti c research personnel, which is the "baton" of scienti c research activities [22] and also the main way to identify the achievements of scienti c research personnel. The data analysis found that the satisfaction of scienti c researchers in S Hospital was (3.68±0.82) in job promotion, (3.70±0.72) in performance assessment, (3.71±0.72) in title evaluation and recruitment, and (3.70±0.68) in the overall scienti c research system, indicating that the scienti c researchers were satis ed with the scienti c research system of the hospital.
The age of researchers has an impact on job satisfaction. The results showed that researchers aged 30-39 and over 50 had the lowest overall job satisfaction, while those aged 40-49 had the highest overall job satisfaction, followed by those aged under 29. Combined with the difference analysis of the results, it is found that there are also differences in the satisfaction of researchers of different age groups on scienti c research management, salary and bene ts.
To be speci c, researchers aged between 40 and 49 are basically at a stable stage in both family and work, have made certain achievements in the eld of scienti c research, and have a certain academic level and status. They have less pressure on scienti c research, less pressure on life and work, and are more likely to have satisfaction and satisfaction in scienti c research work Researchers aged 29 and under have just entered their jobs, and most of them are unmarried or married and have no children. They have little family pressure, and they are interested in exploring and seeking knowledge in medical scienti c research. They also have more time and energy to engage in scienti c research and are easily satis ed with scienti c research work The reason for the low satisfaction of researchers in the age group of 30-39 is that most of them facing the promotion, the problem such as marriage, raising children, supporting the elderly [23], the situation has a certain restrictions on their scienti c research work, make they don't have enough time and energy to understand the recent developments in related eld, can't clear research direction, multiple pressure affects their scienti c research job satisfaction [24] Over the age of 50 researchers continue to engage in scienti c research is largely because the love for the scienti c research work, the reason for their low satisfaction may be that they are limited by their age when applying for certain projects, but there are also some people who may be due to the decrease of their energy in scienti c research as they grow older.

Suggestions
Improve the salary and welfare level of researchers. Material reward is not only one of the essential conditions to meet the physiological needs of researchers, but also a kind of a rmation to their scienti c research work. Those engaged in medical scienti c research are mainly highly educated talents with a master's degree or above, who tend to have a higher achievement orientation [25][26]. When their physical needs are satis ed, they pursue higher needs. Therefore, hospitals need to establish a more fair, just and reasonable salary and welfare system, establish a good incentive mechanism [27,28], and practically improve the treatment level of scienti c researchers, so as to reduce their economic pressure and improve their enthusiasm for scienti c research. In addition, we can also take spiritual incentive measures [29][30], such as hospital leaders care about and attach importance to scienti c research personnel, and set up all kinds of inspiring scienti c research honorary titles, so as to enhance the satisfaction and sense of achievement of scienti c research personnel, so as to improve the e ciency of scienti c research.
Change the concept of scienti c research management, establish and improve the scienti c research management system. Research [31] shows that there is a positive relationship between scienti c research work satisfaction and scienti c research performance. Scienti c research work is a crucial link in the development of hospitals, and the work satisfaction of researchers affects the overall scienti c research level of hospitals [6].In addition to completing heavy clinical work, researchers also need to invest a lot of time and energy to carry out scienti c research [32]. Therefore, the hospital should change its concept in scienti c research management, adhere to the principle of "people-oriented", emphasize the performance of scienti c research, and pay attention to the needs of scienti c researchers. Hospital leaders and policy makers need to make efforts to design and implement strategies that can alleviate the work pressure of researchers and balance their work and family life [33], so as to solve their worries, protect their rights and interests, continuously improve their work satisfaction, and ultimately promote the overall scienti c research level of the hospital.
Targeted measures should be taken for researchers with low satisfaction. the satisfaction of researchers is jointly affected by their subjective consciousness and objective environment [5]. Therefore, hospital managers should take into account the differences between different groups when improving their satisfaction. For 30-39 scienti c research personnel, the hospital can be understand by conducting seminars and other forms of di culties and requirements of their current work, to take targeted measures to help them to solve di culties, can also provide more learning resources and independent space for researchers by improving the hospital research platform, library system, updating laboratory equipment, setting up study rooms, etc, create a strong academic atmosphere, through the promotion of soft and hard conditions to improve their scienti c research satisfaction [34].For researchers aged 50 and over, appropriate preferential policies should be adopted to apply for research projects according to their own abilities and needs. Seminars can also be held so that outstanding researchers with rich experience and outstanding scienti c research achievements can impart experience, skills and solve doubts to young researchers, so as to improve the satisfaction of researchers and improve the overall scienti c research level of the hospital.

Conclusion
Hospital researchers are a special group, and there are few researches on their job satisfaction. Through this survey, it is found that the job satisfaction of researchers is composed of and affected by multiple dimensions, among which the scienti c research system has the most in uence, and the improvement of salary and welfare level is a problem that must be solved in the process of continuously improving the satisfaction. In future studies, the scope can be expanded to focus on the job satisfaction of researchers at different levels of hospitals.
