Estresse ocupacional e fadiga como preditores da síndrome de Burnout em médicos docentes

Abstract

The objective of this research was to investigate the role of fatigue and occupational stress as predictors of Burnout in medical teachers. The study included 60 doctors, professors of medicine courses in Alagoas. We used a questionnaire to survey demographic and professional variables, the Maslach Burnout Inventory (MBI), the Work Stress Scale and the Fatigue Assessment Scale. The data collected were analyzed in three steps. At first, descriptive statistics were performed and decision making (Student's t test) to compare the mean scores of the constructs considered here, depending on labor assignments. In the second analysis was performed on the correlation (Pearson's r) and multiple linear regressions to check the level of relationship and the extent to which independent variables explain the consequent variables. Finally, we proceeded to a structural equation modeling to test the theoretical model. The results of the comparison between the mean scores obtained in the variables measured on the basis of indicators of job-assignments, showed that teachers who guide students to extend, on average, higher scores on factor demand than those who do not develop this activity. The results of correlation analysis showed high and significant correlations between factors of the three scales. The multiple regression showed that fatigue and social support predict emotional exhaustion, depersonalization is predicted only by the demand variable, while the control variable accounts for professional achievement. With regard to testing the theoretical model explaining the dimensions of Burnout, as scores of fatigue and stress factors at work, the results obtained by means of structural equation modeling showed the same pattern of regression analyzes. Based on the findings of this study, it is reiterated that the nature predictor variables fatigue and occupational stress have on the process of Burnout in medical teachers.
