Data came from questionnaires completed anonymously by 828 male and female Canadian police officers. Eight phases of burnout were defined using high and low divisions on the three subscales of the Maslach Burnout Inventory. Measures of work setting, experienced stress, and emotional and physical well-being were significantly related to progressive phases of burnout. Individuals in more advanced phases of burnout tended to be older, in policing longer, and of higher rank. They also drank more alcohol and coffee, smoked more cigarettes per day, and exercised less. Almost half the sample were in either the least or the most burned-out phase. Data tables and 16 references.
