Fig. 1From: Effect of stress coping ability and working hours on burnout among residentsAverage Maslach Burnout Inventory (MBI) subscale scores in the high and low Sense of Coherence (SOC) scale groups by working hours (− 9: ≤9 h/day; − 11: > 9 to 11 h/day; − 13: > 11 to 13 h/day; and 13–: > 13 h/day). MBI-EX: MBI-emotional exhaustion; MBI-CY:MBI-cynicism; MBI-PE:MBI-professional efficacy. The area with blue shadowing indicates clinical burnout or abnormally low professional efficacy. Low SOC: residents with a score of ≤45 on 10 items of the SOC scale (SOC10); High SOC: residents with a score > 45 on the SOC10. The significance of independent variables (h, SOC) and their interactions calculated by two-way analysis of variance for each MBI subscale score are indicated. *p < 0.05; **p < 0.01Back to article page
