Table 3 gives results of the RWAs. Among MDs, a weighted linear
combination of 6 predictor variables included in the model explained
more than 50% of the variance in emotional exhaustion
(R 2=0.53) but explained a lower proportion of
variance in depersonalization (R2 =0.30) and
reduced personal accomplishment (R2 =0.21).
Frustration explained a statistically significant proportion of variance
in the three burnout dimensions: 49.5% in emotional exhaustion, 87.9%
in depersonalization, and 48.7% in reduced personal accomplishment.
Effort (14.5%) and temporal demand (20.0%) also explained a
significant portion of variance in MD emotional exhaustion.
