Out of 176 RADs undergraduate students enrolled in CoAMS, 96 [3rd year = 38 (25 male; 13 female), 4th year = 58 (26 male; 32 female) students] of them agreed to participate, resulting in a 54.5% overall response rate. Of the 58 fourth-year students participating, 46 (77.3 %) were enrolled in the CT & MRI track, 9 (15.5 %) in the ultrasound track, and 3 (5.2 %) in the VIR track. There was also no statistically significant difference in the mean scores of fourth-year students between tracks on all items comprising the emotional exhaustion, cynicism, and professional efficacy dimensions. Descriptive and inferential statistics of the 96 RADS undergraduate students are shown in Table 1. Internal consistencies (Cronbach’s alpha) for the three subscales of MBI-GS (S) of the whole sample were good and acceptable (α > 0.70) “exhaustion (3rd year α = 0.78; 4th year α = 0.85), cynicism (3rd year α = 0.73; 4th year α = 0.76), and professional efficacy (3rd year α = 0.825; 4th year α = 0.83).

Male vs. Female:
The mean scores of burnout dimensions among RADs male and female students are shown in Fig. 1, the supporting numerical data is listed in Table 1. Third-year male and female students’ emotional exhaustion mean scale scores were (17.0 ± 6.3 and 13.7 ± 8.6, respectively), showing no statistically significant difference (P = 0.18) between groups (i.e., male vs. female). Fourth-year male and female students’ emotional exhaustion mean scale score were (18.0 ± 6.5 and 20.3 ± 7.0, respectively), with no statistically significant difference (P = 0.16). Additionally, there was no statistically significant difference between the mean scores of male and female students (i.e., third year and fourth year) for each individual item making up the emotional exhaustion dimension.
Third-year male and female students’ cynicism mean scale scores were (13.8 ± 6.8 and 10.3 ± 7.1, respectively), whereas fourth-year male and female students’ mean scale scores were (13.0 ± 6.0 and 16.3 ± 7.6, respectively) showing no statistically significant difference between groups (i.e., male vs. female) with p-values of 0.15 for third-year students and 0.07 for fourth-year students. Third-year male students’ cynicism means scores for items 13 and 14 were significantly higher compared to female students (P = 0.045, and 0.044, respectively), indicating that male students were more cynical than females. There was no statistically significant difference between the mean scores of third year male and female students on the other items making up the cynicism dimension. Additionally, there was no statistically significant difference between the mean scores of fourth year male and female students on all items making up the cynicism dimension.
Third-year male and female students’ professional efficacy mean scale scores were (24.8 ± 6.4 and 22.5 ± 10.9, respectively), showing no statistically significant difference between groups (i.e., male vs. female) (P = 0.97). In contrast, fourth-year male and female students’ professional efficacy mean scale score were (26.1 ± 7.9 and 21.1 ± 8.0, respectively), showing statistically significant difference between groups (P = 0.007), and indicating higher burnout levels for females. Fourth-year female students’ professional efficacy means scores for items 7, 10 and 16 were significantly lower compared to male students (P = 0.01, 0.01, and 0.02, respectively). There was no statistically significant difference between the mean scores of fourth year male and female students on the other items making up the professional efficacy dimension. Additionally, there was no statistically significant difference between the mean scores of third year male and female students on all items making up the professional efficacy dimension.
Third year vs. Fourth-year students:
Fourth-year students emotional exhaustion mean scale score was 19.3 ± 6.8 indicating significant higher burnout levels (P = 0.042), compared to third-year students mean scale score of 15.9 ± 7.2 Table 1. Furthermore, the fourth-year students emotional exhaustion mean scores for items 1, and 4 were significantly different compared to third-year students (P = 0.049, and 0.022, respectively). Fourth-year female students’ emotional exhaustion means scores for items 1, 4, and 6 were significantly higher compared to third-year female students (P = 0.05, 0.005, and 0.014, respectively). There was no statistically significant difference between the mean scores of third year and fourth-year female students on the other items making up the emotional exhaustion dimension. Additionally, there was no statistically significant difference between the mean scores of third year and fourth-year male students on all items making up the emotional exhaustion dimension.
Fourth-year female students cynicism mean scale score was 16.3 ± 7.6 indicating significant higher burnout levels (P = 0.035), compared to third-year female students mean scale score of 10.3 ± 7.1.
Fourth-year female students’ cynicism means scores for items 13, 14, and 15 were significantly higher compared to third-year female students (P = 0.006, 0.014, and 0.016, respectively). There was no statistically significant difference between the mean scores of third year and fourth-year female students on the other items making up the cynicism dimension. Additionally, there was no statistically significant difference between the mean scores of third year and fourth-year male students on all items making up the cynicism dimension.
There was also no statistically significant difference between the mean scores of third year and fourth year (male and female) students on all items making up the professional efficacy dimension.
Interpretation of MBI-GS (S) scores:
Table 2 summarizes the classification cut-off values of MBI–GS (S) scales’ scores for all radiological sciences’ undergraduate students into low, moderate, or high risk of burnout; the interpretation of MBI–GS (S) scales’ scores for all students is listed in Table 3 and illustrated in Fig. 2a-c. For the whole sample (Fig. 2a), the percentage of students who were at moderate to high risk of burnout for emotional exhaustion, cynicism, and professional efficacy were 70.8%, 75% and 74% respectively; the percentage of male students who were at moderate to high risk of burnout for emotional exhaustion, cynicism, and professional efficacy were 70.6%, 78.4% and 62.8% respectively; and the percentage of female students who were at moderate to high risk of burnout for emotional exhaustion, cynicism, and professional efficacy were 71%, 71.1% and 86.7% respectively.
