Inpatient Nurses
Similar to providers, a weighted linear combination of the 6 predictor variables explained a high proportion of variance in emotional exhaustion among inpatient nurses (R2 =0.55) but explained a smaller level of variance in depersonalization (R2 =0.28) and reduced personal accomplishment (R2 =0.19). Three variables explained a significant proportion of variance in emotional exhaustion with the most important variable being frustration (71.0% of variance), followed by temporal job demand (10.4% of variance), and effort job demand (7.9% of variance). For depersonalization, frustration explained 60.2% of variance, PSE involvement explained 16.8%, and temporal job demand explained 9.6%. Only frustration significantly explained variance in reduced personal accomplishment among inpatient nurses with 79.8% of variance explained.
