1. Background
The concept of job burnout, a prolonged psychosomatic
response to chronic emotional and interpersonal stressors at
work, was introduced in 1974 by US psychologist Herbert
Freudenberger [1]. The three core dimensions of job burnout
are emotional exhaustion (EE), depersonalization (D), and
feelings of decreased personal accomplishment (PA) [2].
Emotional exhaustion is the feeling of fatigue and weakness at
work; depersonalization is the loss of personal identity; and
personal accomplishment is feeling productive and adequate
and coping successfully [3]
