Validation of a single-item measure of burnout against the Maslach Burnout Inventory among physicians

The measurement of burnout among physicians is important because physician well-being has the potential to affect workforce stability and quality of care. In this study, a single-item measure of burnout was validated against the sub-scales of the Maslach Burnout Inventory (emotional exhaustion, depersonalization, and personal accomplishment). Survey items included the 22-item Maslach Burnout Inventory, a single-item measure of burnout, and other questions regarding demographics, practice characteristics, and occupational satisfaction. The surveys were mailed to Texas Tech University School of Medicine Alumni classes of 1980-1989. The response rate was 43 per cent (n = 307). Pearson correlation coefficients and ANOVA were used to determine the association between the Maslach Burnout Inventory scores and the single-item burnout question. The single-item was correlated at r = 0.64 (p < 0.0001) with emotional exhaustion and the ANOVA yielded an R-2 of 0.5 (p < 0.0001). Hence, in surveys of physicians where emotional exhaustion is the primary sub-scale of interest, a single-item measure of burnout may be used as an alternative to the Maslach Burnout Inventory in order to abbreviate survey material and potentially increase response rates among physicians.
