3.1. Demographic and Professional Characteristics of Emergency Department Staff
The results present the characteristics of the 184 participants in the study. Most participants were female (71.7%), and the largest professional category was nurses (52.7%). The education level of the participants was mainly university studies (46.7%). Additionally, the majority of participants reported working night shifts (87.0%), and most of them worked in the hospital setting (73.9%) (
Table 1).
The mean age of the sample is 39.56 years old, with a standard deviation of 8.25. The median age is 39 years old. The age distribution is slightly skewed to the right, as indicated by a positive skewness value of 0.48, but this skewness value is relatively small. The kurtosis value of −0.12 suggests the platykurtic distribution, meaning it has thinner tails and a flatter peak than a normal distribution.
The mean of the years in the field is 10.92, with a standard deviation of 7.42. The median of the years in the field is ten years. The distribution of years in the field is moderately skewed to the right, as indicated by a positive skewness value of 0.78. The kurtosis value of −0.139 suggests that the distribution is also platykurtic.
Overall, the sample has a relatively normal distribution for age and years in the field, with moderate variability in both variables.
3.2. Descriptive Statistics for AWS, JSS, and MBI-HSS (MP)
We evaluated each scale’s scores (JSS, AWS, and MBI-HSS MP) in order to identify the study group satisfaction based on the individual parameters of the applied scales. However, since the scales do not have specific cut-off points, higher scores were correlated with higher burnout symptoms.
3.2.1. Descriptive Statistics for Areas Work Survey
Table 2 provides descriptive statistics for six variables: workload, control, reward, community, fairness, and values, representative of the AWS scale. The mean value for each variable indicates the average score for that variable, with the highest mean value being for the community variable (M = 3.61, SD = 0.75) and the lowest being for the workload (M = 3.09). The highest standard deviation was found for the workload variable (SD = 0.94), indicating a more significant variability in the scores than the other variables. Based on these results in
Table 2, we can deduce that the group presented a median AWS score of 3.5, meaning that most subjects had low levels of dissatisfaction with workload, control, reward, community, fairness, and values.
The skewness values indicate the degree of symmetry in the distribution of each variable’s scores. Positive skewness values for the workload (S = 1.47) and control (S = 1.92) variables suggest that most scores are lower than the mean, with a few high scores skewing the distribution. The remaining variables have skewness values close to zero, indicating relatively symmetrical distributions.
The workload (K = 10.18) and control (K = 12.6) variables have very high kurtosis values, suggesting a peaked distribution. On the other hand, the community, fairness, and values variables have negative kurtosis values, indicating a relatively flat distribution (
Table 2).
3.2.2. Descriptive Statistics for Job Satisfaction Survey
Table 3 displays descriptive statistics for the nine subscales in the JSS; pay, promotion, supervision, fringe benefits, contingent reward, operating conditions, coworkers, nature of work, and communication.
The mean column shows the average score for each variable, with the highest mean score being for the nature of work (M = 19.09) and the lowest for operating conditions (M = 11.15). The median for most variables is around 14, except for the nature of work and communication, where the median score is higher. The standard deviation column shows the variability in the responses for each variable, with the highest standard deviation being for fringe benefits (SD = 4.22) and the lowest being for operating conditions (SD = 2.89) (
Table 3).
Most variables have skewness values close to zero, except for coworkers, which had a positive skewness value. Most variables have kurtosis values close to zero, except for the nature of work and communication, which had negative kurtosis values (
Table 3).
Table 3 also provides descriptive statistics for total satisfaction. The mean value of this variable is 134.84, indicating that the respondents, on average, report a relatively high level of satisfaction. The median value of 133.5 is close to the mean, suggesting that the distribution of responses may be symmetric.
The standard deviation of 23.61 indicates some variability in the responses, with some respondents reporting much lower or higher satisfaction levels than others. The positive skewness value of 0.36 suggests that the distribution may be skewed to the right, meaning that a few respondents may report very high satisfaction levels. The descriptive statistics indicate the respondents are generally satisfied, with some variability in their responses (
Table 3).
These results provide a quantitative basis for identifying areas of strength or concern, guiding interventions, and designing strategies to enhance employee well-being and organizational performance.
3.2.3. Descriptive Statistics for MBI-HSS (MP)
The MBI-HSS (MP) scale was evaluated using the three subscales presented in the previous chapter. For emotional exhaustion, the mean is 20.38, indicating a slightly left-skewed distribution. The standard deviation of 10.41 indicates a relatively wide dispersion of values around the mean. The negative skewness value of 0.22 suggests that the data are slightly skewed to the left. The negative kurtosis value of −0.57 indicates that the distribution is somewhat flatter than a normal distribution, with fewer extreme values (
Table 4).
For depersonalization, the mean is 8.67, indicating a slightly right-skewed distribution. The standard deviation of six indicates a relatively narrow dispersion of values around the mean. The positive skewness value of 0.364 suggests that the data are slightly skewed to the right. The negative kurtosis value of −0.76 indicates that the distribution is less peaked than a normal distribution, with fewer extreme values (
Table 4).
For personal accomplishment, the mean is 38.05, indicating a slightly left-skewed distribution. The standard deviation of 7.65 indicates a relatively narrow dispersion of values around the mean. The negative skewness value of −1.15 suggests the data are moderately skewed to the left. The positive kurtosis value of 1.93 indicates that the distribution peaked more than a normal distribution, with more extreme values (
Table 4).
By examining these statistics, we gain insights into the levels and variations of emotional exhaustion, depersonalization, and personal accomplishment among employees. This information can provide further information for targeted interventions to address burnout, enhance employee well-being, and promote a positive work environment.
3.3. Analysis of Relationships between MBI-HSS (MP), JSS, and AWS
Furthermore, we analyzed the relationship between the values identified within MBI-HSS (MP) scales and the items within the JSS and AWS surveys.
Table 5 and
Table 6 give the result of the variance analysis. The F and Significance F (sig.) values give us important elements that underlie the validation of the regression model. Statistical F test the overall significance of independent variables and the significance F is the value of the error we can make by rejecting the regression model as inappropriate. Regression model acceptance decision rule: higher values for F statistics and lower values for F significance.
Firstly, we studied the relationship between the MBI-HSS (MP) subscale and AWS. Our main objective was to analyze the degree of DP, EE, and AP according to the variables and scores identified in AWS (workload, control, reward, community, fairness, and values), in this particular situation the results from AWS became independent variables, influencing the MBI-HSS scores. We used the linear regression model to identify any connection between the dependent variables of EE, DP, and AP and the independent variables of workload, control, reward, community, fairness, and values.
Table 5 shows the results of three separate ANOVA tests performed on EE, DP, and AP and AWS scales.
For EE, the F-statistic is 1.98, and the significance level is 0.071, slightly higher than the commonly used threshold of 0.05. This indicates that there may be a significant relationship between the AWS scale variables and EE. The residual sum of squares shows significant unexplained variation in the data (
Table 5).
For DP, the F-statistic is 0.4, and the significance level is 0.878. This suggests that no significant relationship exists between the AWS scale variables and DP. The residual sum of squares indicates less unexplained variation in the data than EE (
Table 5).
For AP, the F-statistic is 1.299 and the significance level is 0.260. This indicates that there may be a significant relationship between the AWS scale variables and AP. The residual sum of squares shows significant unexplained variation in the data (
Table 5).
Furthermore, we analyzed the degree of DP, EE, and AP according to the variables and scores identified in the JSS survey. The ANOVA results for the EE variable indicate a significant relationship between total satisfaction, operating condition, nature of work, promotion, fringe benefits, pay, communication, coworkers, contingent reward, and supervision. The sum of squares indicates that the model explains a significant proportion of the variability in EE. The F-statistic for the regression model is 9.014, which indicates that the regression model is significant. The significance level for the regression model is 0.000, less than the conventional alpha level of 0.05, meaning the regression model is highly significant (
Table 6).
The regression model for DP has an F-statistic of 4.24, and the significance level is 0.000, indicating a significant relationship between the JSS scales and DP variables. The residual sum of squares and the mean square indicates that there is still some unexplained variation in the model (
Table 6).
The regression model for AP has an F-statistic of 5.626, and the significance level is 0.000, indicating a significant relationship between the dependent variable and at least one of the independent variables (
Table 6).
Further, we analyzed the statistical relationship using the Pearson correlation coefficients and significance values (two-tailed) between the variables of EE (emotional exhaustion), DP (depersonalization), and AP (personal accomplishment), as well as the sub-scales of the Areas of Work Scale (AWS) and the Job Satisfaction Survey (JSS) (
Table 7).
The Pearson correlation coefficients range from −1 (a perfect negative correlation) to 1 (a perfect positive correlation). A correlation coefficient of 0 indicates no correlation. The significance values indicate whether the correlation coefficients are statistically significant (
Table 7).
Emotional exhaustion is negatively correlated with all sub-scales of both the AWS and JSS. Specifically, the Pearson correlation coefficients range from −0.189 to −0.538, and the significance values range from 0.000 to 0.015 for the AWS sub-scales and from −0.280 to −0.478 and 0.000 to 0.014 for the JSS sub-scales. These negative correlations suggest that higher levels of emotional exhaustion are associated with lower levels of job satisfaction. This is an important finding as emotional exhaustion is a significant component of burnout, and these results suggest that addressing emotional exhaustion may be critical in improving job satisfaction. Depersonalization is positively correlated with the operating condition and coworker sub-scales of the JSS. The correlation coefficients are 0.246 and 0.347, respectively, and both are significant at the 0.05 level or lower. This suggests that satisfaction with operating conditions and coworkers decreases as depersonalization increases (
Table 7).
Personal accomplishment (AP) is positively correlated with all sub-scales of the JSS, with correlation coefficients ranging from 0.148 to 0.392. All values are significant at the 0.05 level or lower. This suggests that as personal accomplishment increases, job satisfaction increases across all sub-scales of the JSS (
Table 7).
3.4. Relationship between Professional Categories and Burnout Levels
Table 8 presents the mean, standard deviation, skewness, and kurtosis for the variables EE for different professional categories, including specialist doctors, primary doctors, resident physicians, nurses, carers, stretcher-bearers, paramedics, and registry workers.
By comparing the levels of EE, it can be observed that the highest mean scores are found in specialist physicians (M = 26.5) and primary physicians (M = 24.6), followed by nurses (19.8), stretcher-bearers (M = 20.3), registry workers (M = 21.7), resident physicians (15.6), carers (15.6), and paramedics (M = 13.1). This suggests that specialists and primary physicians experience higher emotional exhaustion levels than the other professional categories (
Table 8).
In terms of DP, the highest mean score is found in specialist doctors (M = 11.9), followed by primary doctors (M = 12.1), registry workers (M = 12.0), nurses (M = 7.9), paramedics (M = 8.1), resident physicians (M = 8.4), carers (M = 3.0), and stretcher-bearers (M = 5.3). This indicates that specialist and primary doctors and registry workers experience higher levels of depersonalization than the other professional categories (
Table 8).
Regarding AP, the highest mean score is found in resident physicians (M = 42.3), followed by stretcher-bearers (M = 39.6), paramedics (M = 39.14), nurses (M = 38.2), primary doctors (M = 36.9, carers (M = 36.1), specialist doctors (M = 37.0), and registry workers (M = 30.5). This suggests that resident physicians, stretcher-bearers, and paramedics experience higher levels of personal accomplishment than other professional categories (
Table 8).
