Burnout Comparison between Clinical and Basic Sciences Faculty of a Medical School and Evaluation of Related Factors

Objective: It has been shown that clinical practice may be a risk factor for job burnout. On the other hand, annual income may have a protective effect on job burnout. Clinical faculty in contrast to basic sciences faculty members have higher income but are involve in clinical practice. Comparison between these two groups can clarify which factors have greater influence on burnout. As a second aim for this study, reliability and validity of the Persian version of Maslach burnout inventory general survey (MBI-GS) were evaluated as well. Method : This cross-sectional study was conducted at Shiraz Medical School in Iran and a total of 241 faculty members were randomly selected and burnout was measured by the Persian version of the Maslach burnout inventory general survey (MBI-GS). Results: Comparison of burnout between the two groups indicated that clinical faculty showed significantly higher scores in the exhaustion dimension compared to the basic sciences faculty (p value = 0.017) but no significant differences were found between the two groups in other dimensions. Job satisfaction and income satisfaction were negatively correlated with exhaustion and cynicism dimensions, and job satisfaction was positively associated with professional efficacy (p value > 0.05). Internal consistency of the questionnaire was acceptable (α=0.77). Scaling success rate for discrimination and convergent validity were 100% except for convergent validity in the cynicism subscale. Correlation of all questions with their dimensions was equal to or more than 0.4 with the exception of item 13 in the cynicism subscale. Conclusion: Clinical faculty had higher burnout than basic sciences faculty especially in the exhaustion dimension. It has also been shown that income and job satisfaction are the most important factors which can predict professional burnout in medical faculty members. It is important for administrative and organizational decision makers to improve job engagement and decrease job abandonment. This study largely confirmed the 3-dimensional structure of the Persian version of MBI-GS.
