MBI-EX Maslach Burnout Inventory-emotional exhaustion
MBI-CY Maslach Burnout Inventory-cynicism
MBI-PE Maslach Burnout Inventory-professional efficacy
Low SOC: Respondents whose score on the 10-item Sense of Coherence Scale was ≤45
High SOC: Respondents whose score on the 10-item Sense of Coherence Scale was > 45
n: number of respondents. SD standard deviation
*p < 0.05; **p < 0.01: Significant difference in average MBI subscale scores between the low and high SOC groups based on a t-test, and in Pearson correlation analysis of MBI subscale scores and working hours
d:Cohen’s d effect size
1-β: Power of analysis
r: Pearson correlation coefficient
