In this chapter, we take our first look at a full structural equation model (SEM). The hypothesis to be tested relates to the pattern of causal structure linking several stressor variables considered to contribute to the presence of burnout. Of primary interest here, however, was identification of the key determinants of teacher burnout. The original study from which this application is taken (Byrne, 1994b), tested and cross-validated the impact of organizational and personality variables on three dimensions of burnout for elementary, intermediate, and secondary teachers. For purposes of illustration here, however, the application is limited to secondary teachers only (N = 1430).
