Model 1 evaluates variance in UWES explained by WAAQ while controlling for Unit (ICU, PICU). Model 2 evaluates variance in UWES explained by WAAQ while controlling for unit (ICU, PICU) and distress (PSS-10 and GHQ-12). WAAQ, work-related acceptance and action questionnaire; PSS-10, perceived stress scale, 10-item version; UWES, Utrecht work engagement scale; GHQ-12, general health questionnaire, 12-item version; Regressions were computed with listwise deletion of incomplete cases (N = 122–132); aStandardized beta coefficients are presented for the whole model (step 2 in model 1, and step 3 in model 2); bUnits were coded as 0 (PICU) and 1 (ICU); *p < 0.05, **p < 0.01.
