This study was designed to develop instruments to measure employee burnout. The Matthews Burnout Scale for Employees is a 50-item self-report measure. The Matthews Burnout Scale for Supervisors is a 50-item scale for use in evaluating employee burnout. Content-based items were tested for construct validity with a group of employees, and their supervisors, previously identified as being on the extreme ends of the burnout continuum. Discriminant analysis was used to determine those items which were successful in identifying the two groups. The resulting questionnaires are content and construct valid. Subsequent study with employees and their supervisors from a wide variety of workplaces established that both scales have high reliabilities and may be used in the workplace and research. Diagnosis of employee burnout enables the organization to institute intervention, or preventive, strategies. Items being considered for new questionnaires, the burnout scales, and the means and standard deviations of the instruments are included in the appendices. (DWH)
