Bm. Byrne, THE MASLACH BURNOUT INVENTORY - TESTING FOR FACTORIAL VALIDITY AND INVARIANCE ACROSS ELEMENTARY, INTERMEDIATE AND SECONDARY TEACHERS, Journal of occupational and organizational psychology, 66, 1993, pp. 197-212
The purposes of the study were: (a) to test for the factorial validity
of the Maslach Burnout Inventory (MBI) separately for elementary (N =
1159), intermediate (N = 388) and secondary (N = 1384) teachers; (b)
given findings of inadequate model fit, to propose and test an alterna
tive factorial structure; (c) to cross-validate this structure across
an independent sample for each teacher group; and (d) to test for the
equivalence of item measurements and theoretical structure across thes
e three teaching panels. Although confirmatory and exploratory factor
analytic findings supported a three-factor structure, the deletion of
two items (nos 12 and 16) yielded a better fitting model that was, for
the most part, psychometrically and structurally invariant across gro
ups. This study is the most rigorous to date in testing the factorial
validity of the MBI in general, and as it bears on members of the teac
hing profession in particular.
