The Burnout Clinical Subtype Questionnaire BCSQ-12 comprising the dimensions of overload lack of development and neglect is proposed as a brief means of identifying the different ways this disorder is manifested. The aim of the study is to test the construct and criterial validity of the BCSQ-12. Method A cross-sectional design was used on a multi-occupational sample of randomly selected university employees n 826 . An exploratory factor analysis EFA was performed on half of the sample using the maximum likelihood ML method with varimax orthogonal rotation while confirmatory factor analysis CFA was performed on the other half by means of the ML method. ROC curve analysis was preformed in order to assess the discriminatory capacity of BCSQ-12 when compared to MBI-GS. Cut-off points were proposed for the BCSQ-12 that optimized sensitivity and specificity. Multivariate binary logistic regression models were used to estimate effect size as an odds ratio OR adjusted for sociodemographic and occupational variables. Contrasts for sex and occupation were made using Mann-Whitney U and KrusKall-Wallis tests on the dimensions of both models. Results EFA offered a solution containing 3 factors with eigenvalues 1 explaining 73.22 of variance. CFA presented the following indices c2 112.04 p 0.001 c2 gl 2.44 GFI 0.958 AGFI 0.929 RMSEA .
