A study of the consistency of burnout over time.

Burnout over time in teachers in examined in this study using the three subscales of the Maslach Burnout Inventory, Emotional Exhaustion, Depersonalization, and Lack of Personal Accomplishment. Measures were obtained twice, one year apart. LISREL structural equation analysis was used to test a model which predicted specified relationships among burnout components from time one to time two. Results showed that burnout components were consistent over time. Additional data suggest that one of the burnout components, emotional exhaustion, is a mediator between environmental demands and other burnout components.
