The overall fit of Model 1 is significant compared to the baseline Model 0, (2) = 165.93, p < .001. Model 1 accounts for 29.9% or 44.1% of the variance in burnout (depending on which measure of you use). The overall fit of Model 2 is significant after adding the new variables (teaching, research, and pastoral), (3) = 42.98, p < .001. The final model accounts for 36.1% or 53.1% of the variance in burnout (depending on which measure of you use).


Based on the Coefficients table below, we can make conclusions about individual predictors based on their Wald statistics, p-values, and odds ratio’s (including their confidence intervals). For Model 1, both predictors seem to significantly predict burnout. For Model 2, all predictors except for research seem to significantly predict burnout. Since ‘Burnt Out’ is coded as 1, an odds ratio greater than 1 (or regression estimate that is positive) indicates that an increase in a variable is likely to occur with an increase in burnout.

Write it up!

In terms of the individual predictors we could report the following: Burnout is significantly predicted by perceived control, coping style (as predicted by Cooper), stress from teaching and stress from giving pastoral care. The value and direction of the beta weights tell us that, for perceived control, coping ability and pastoral care, the relationships are positive. That is (and look back to the question to see the direction of these scales, i.e., what a high score represents), poor perceived control, poor ability to cope with stress and stress from giving pastoral care all predict burnout. However, for teaching, the relationship if the opposite way around: stress from teaching appears to be a positive thing as it predicts not becoming burnt out.
