Exploratory factor analysis revealed five factors with eigenvalues greater than 1. The three subscales showed good internal reliability with Cronbach’s alpha coefficients exceeding the critical value of 0.7. Goodness-of-fit was assessed by means of the chi-square ratio by the degrees of freedom, the standardized root mean square residual (SRMR), the root mean square error of approximation (RMSEA), the Tucker-Lewis Index (TLI) and the comparative fit index (CFI). A principal axis exploratory factor analysis with an oblique transformation of the solution and a confirmatory factor analysis with maximum likelihood estimation were performed. The sampling adequacy was assessed using the Kaiser-Meyer-Olkin measure along with the Bartlett’s test of sphericity. Internal reliability was estimated using Cronbach’s alpha coefficient. Burnout was measured using the Spanish validated version of the MBI-HSS. MethodsĬross-sectional study including 259 healthcare emergency professionals (physicians and nurses) in the Spanish health region of Lleida and the Pyrenees. The goal of the present study was to assess the internal reliability and the performance of the items and the subscales of the MBI-HSS (the version for professionals working in human services) by validating its factorial structure in Spanish urgency healthcare personnel. Nevertheless, confirmatory factor analysis showed a relatively satisfactory fit of the three-factor structure (χ 2/df = 2.6, SRMR = 0.07, RMSEA = 0.08, TLI = 0.87, CFI = 0.89), which was improved when several items were removed (χ 2/df = 1.7, SRMR = 0.04, RMSEA = 0.05, TLI = 0.97, CFI = 0.98).Īlthough it is necessary exploring new samples to get to more consistent conclusions, the MBI-HSS is a reliable and factorially valid instrument to evaluate burnout syndrome in health professionals from the Spanish emergency services.īurnout, Psychological Emergencies Factor Analysis, Statistical Maslach Burnout Inventory – Human Services Survey Psychometrics.The Maslach Burnout Inventory (MBI) is an instrument commonly used to evaluate burnout syndrome.
