Evidences of validity and reliability of burnout's scale in Cuban dental students
Keywords:
burnout, dentistry, dental students, surveys and questionnaires.Abstract
Introduction: In Cuba, the burnout syndrome has been scarcely investigated, hence the need for valid and reliable instruments for its study.Objective: To analyze the evidence of validity and reliability of the Maslach Burnout Inventory-Students Survey in Cuban dental students.
Methods: Instrumental, cross-sectional and multicenter study, which included students from seven Cuban universities. Using an instrument in Spanish validated in Colombian students, a confirmatory factor analysis was performed, structural equation modeling was used, and internal consistency was calculated with Cronbach's α coefficient.
Results: 738 participants were included, of which 63,69 % were women and the mean age was 21,67 ± 1,70 years. From the initial scale of 15 items distributed in three factors, the factor analysis suggested eliminating items 2, 4, 5 y 10. The final model was made up of 11 items, two for factor 1 (Emotional exhaustion), four for factor 2 (Depersonalization) and five for factor 3 (Lack of personal accomplishment). A Cronbach's α coefficient of 0,81 (95 % CI = 0,78-0,83) was obtained, which indicates that the internal consistency of the instrument is good.
Conclusions: An 11-item academic burnout scale was validated, which has evidence of validity and adequate reliability to evaluate the burnout syndrome in Cuban dental students.
