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 that bear on the construct of burnout. The original study from which this application is taken (Byrne, 1994c) tested and cross-validated the im­ pact of organizational and personality variables on three dimensions of burnout for elementary, intermediate, and secondary school teachers. For purposes of il­ lustration here, however, the application is limited to the calibration sample of secondary school teachers only.
