2.2.5 Maslach Burnout Inventory (MBI)
The MBI, which was originally developed by Maslach and Jackson15, is a self-report instrument to evaluate the intensity and frequency of perceived burnout. The validity and reliability studies of the scale in the Turkish population were conducted by Ergin et al.16. It consists of 22 items and the scores are ranged on a 5-point Likert-type scale. It has three subscales: emotional exhaustion, depersonalization, and professional accomplishment. Emotional exhaustion assesses feelings of being fatigue and emotionally overwhelmed by work. Depersonalization assesses the extent to which an individual responds impersonally and lacking toward others they care for, provide service to, or instruct at work. Personal accomplishment evaluates the perceived personal competence and achievement. The scores range from 0 (never) to 4 (always) for the emotional exhaustion (0-48) and depersonalization (0-30) subscales, while the lower personal achievement subscale scores, which is independent of the other subscales, indicate a higher degree of experienced burnout.
