SIMANCAS-PALLARES, Miguel Angel; FORTICH MESA, Natalia  and  GONZALEZ MARTINEZ, Farith Damián. Validity and internal consistency of the Maslach Burnout Inventory in dental students from Cartagena, Colombia. rev.colomb.psiquiatr. [online]. 2017, vol.46, n.2, pp.103-109. ISSN 0034-7450.


To determine the internal consistency and content validity of the Maslach Burnout Inventory-Student Survey (MBI-SS) in dental students from Cartagena, Colombia.

Materials and methods:

Scale validation study in 886 dental students from Cartagena, Colombia. Factor structure was determined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency was measured using the Cronbach's alpha coefficient. Analyses were performed using the Stata v.13.2 for Windows (Statacorp., USA) and Mplus v.7.31 for Windows (Muthén & Muthén, USA) software.


Internal consistency was α = 0.806. The factor structure showed three that accounted for the 56.6% of the variance. CFA revealed: x 2 = 926.036; df=85; RMSEA = 0.106 (90% CI, 0.100-0.112); CFI = 0.947; TLI = 0.934.


The MBI showed an adequate internal consistency and a factor structure being consistent with the original proposed structure with a poor fit, which does not reflect adequate content validity in this sample.
