Career burnout has been recognized as a syndrome marked by mental, physical and emotional exhaustion which is especially prevalent among teachers. Teacher burnout is currently a widely researched phenomenon and controversy over its definition, causes and interventions has been great. Meanwhile, the burnout construct has gained little clarity. The purpose of the present study was to determine whether identifiable personality characteristics, as measured by the Personality Research Form, were consistently associated with burnout in teachers, as measured by the Maslach Burnout Inventory and the Cognitive Burnout Scale. Moderately strong relationships were found between specific personality characeristics and reported levels of burnout. However, individual factors were not concluded to be as critical as the interaction between such factors and the environment. Future directions are discussed.
