The relationship between empowerment, occupational burnout, and job stress among nurses in Rasht Medical Education Centers: A dataset

The data in this article show the relationship between empowerment, occupational burnout and job stress among nurses in medical education centers in the city of Rasht, Iran. This descriptive correlational study was carried out from January 2016 to June 2017. The study sample included 316 nurses working at the teaching hospitals in Rasht; they were selected using stratified random sampling. The data were collected by a standard questionnaire which was rated based on the five-point Likert Scale. Data analysis was performed by SPSS-22 and SmartPLS software. Data analyzing showed that the mean scores of occupational burnout and job stress were lower than the average level. There was a significant relationship between empowerment and job stress and between job stress and occupational burnout. However, there was no significant association between empowerment and occupational burnout. It was discovered that job stress played a mediating role on the relationship between empowerment and occupational burnout.

It was discovered that job stress played a mediating role on the relationship between empowerment and occupational burnout.
& Data were collected by a four-part standard questionnaire. The first section of the questionnaire was on demographic information including gender, age, marital status, education and work experience; the second section (items 1-18) focused on structural empowerment; the third section (items 19-30) analyzed job stress and the fourth section (items 31-52) explored occupational burnout.

Data format
Raw, analyzed

Experimental factors
Scoring was performed based on the five-point Likert Scale. The validity of the scale was examined and confirmed using the views of experts in the field; its reliability was also confirmed by Cronbach's alpha.

Experimental features
The normal distribution of the data was analyzed and approved by Kolmogorov-Smirnov test. SPSS-22 software was used to analyze the descriptive statistics, and because of the low sample size, PLS2 software or least squares approach was used to analyze the fit of the model and to test the research hypotheses.

Data accessibility
The data are available with this data article and its tables.

Value of the data
Nurses, who play a key role in health organizations, experience high levels of job stress and burnout, which might be due to their low or limited capabilities. Moreover, an increase in the level of occupational burnout and stress can adversely affect productivity and efficiency.
Occupational burnout and job stress are among the main problems with which many health organizations are burdened.
The data shown here can be used for the health organizations and medical education centers managers.

Data
Various factors affect the improvement of manpower productivity [1][2][3]. Any organization which provides opportunities for its staff members to gain higher levels of capability is more able to face challenges, guarantees its long-term sustenance [4], and aids its staff having a better work quality and performance [5]. An increase in job stress decreases the motivation for work and, as a consequence, in productivity [6,7].
The results of empowerment, job stress, and occupational burnout sections of the questionnaire were as follows: Empowerment: the minimum score was 1.56, the maximum score was 5, the mean score was 3.65, the standard deviation was 0.65709 and variance was 0.432.
Job stress: the minimum score was 1.00, the maximum score was 4.50, the mean score was 2.47, the standard deviation was 0.63282 and variance was 0.400.
Job burnout: the minimum score was 1.20, the maximum score was 4.41, the mean score was 2.51, the standard deviation was 0.52501 and variance was 0.276.
In general, the findings indicated that the mean score of empowerment was higher than the expected mean [4] and the mean scores of occupational burnout and job stress were lower than the expected mean.

The relationship between empowerment and job stress;
The t-test value on the relationship between structural empowerment and job stress was out of the range ( À 1.96 and 1.96); hence, the hypothesis was accepted. The association level between structural empowerment and job stress was equal to À 0.345 (Table 1).

The relationship between empowerment and occupational burnout
The t-test value on the relationship between structural empowerment and occupational burnout was within the range ( À1.96 and 1.96); thus, the hypothesis was rejected ( Table 2).

The relationship between job stress and occupational burnout
Considering the structural model of the study for the significant coefficient, the t-test value on the relationship between empowerment and job stress was out of the range ( À1.96%1.96); hence, the hypothesis was accepted. The relationship level between job stress and occupational burnout was equal to À 0.886 (Table 3).

The mediating role of job stress on the relationship between empowerment and occupational burnout
To analyze the mediating role of job stress on the relationship between structural empowerment and occupational burnout, Sobel test was used.
In this equation: a: path coefficient between independent and mediator variables b: path coefficient between the mediator and dependent variables S a : standard error of independent and mediator variables S b : standard error of mediator and dependent variables The findings showed a z value of 4 1.96 showing that job stress had a mediating role on the relationship between structural empowerment and occupational burnout. Considering the coefficients between structural empowerment and job stress and between job stress and occupational burnout, it can be said that the relationship between structural empowerment and occupational burnout, with the mediating role of job stress, was equal to 0.298.

Experimental design, materials and methods
This descriptive correlational study was carried out from January 2016 to June 2017. The study population consisted of 1586 nurses working in Alzahra, Poursina, Razi, Dr. Heshmat, 17Shahrivar, Amiralmomenin, Shafa and Velayat hospitals, who were selected using Cochran's sample size formula: A sample of 316 nurses was obtained from the calculations and questionnaires were distributed in each hospital using stratified random sampling, as presented in Table 4 below.
Data were collected by a four-part standard questionnaire. The first section of the questionnaire was on demographic information including gender, age, marital status, education and work experience; the second section (items 1-18) focused on structural empowerment [8]; the third section (items 19-30) analyzed job stress [9], and the fourth section (items 31-52) explored occupational burnout [10]. Scoring was performed based on the five-point Likert Scale. The validity of the scale was examined and confirmed using the views of experts in the field; its reliability was also confirmed by Cronbach's alpha ( Table 5).
The normal distribution of the data was analyzed and approved by Kolmogorov-Smirnov test. SPSS-22 software was used to analyze the descriptive statistics, and because of the low sample size, PLS2 software or least squares approach was used to analyze the fit of the model and to test the research hypotheses.
