Burnout isn't one feeling — it's three specific, measurable dimensions, according to the most validated research tool in the field.
The Maslach Burnout Inventory, first published in 1981 by Christina Maslach with colleagues Susan Jackson and Michael Leiter, remains the most cited and most validated burnout assessment tool in existence, used in thousands of studies across dozens of countries. It measures three distinct dimensions: emotional exhaustion, depersonalization, and reduced personal accomplishment — each capturing a genuinely different aspect of the burnout experience.
This guide covers what each dimension actually means and how they combine into the full picture of burnout.
