Theseburnout measures were compared with respect to their psychometric char-acteristics and factorial validity in two groups of professionals, humanservice and other professionals (N 196 and 226, respectively), whocompleted questionnaires at work. As hypothesized, the conrmatory factoranalyses supported a two-factor and a three-factor structure invarianceacross the two groups considered for the SMBM and the MBI-GS, respec-tively, with superior t found for the SMBM.
