Table 2 Mean values, reliability and factor analysis of CDI items (physicians and nurses)

From: Work stress associated cool down reactions among nurses and hospital physicians and their relation to burnout symptoms

CDI single items Mean ± SD Corrected Item - Scale Correlation α if Item deleted (α = .87) Loading Factor 1 (α = .83) Loading Factor 2 (α = .80)
Factor 1: Perception of emotional distance (eigenvalue: 4.3; 34% explained variance)
 CDI 8 – some of them simply annoy me 5.8 ± 2.9 0.60 0.85 0.79  
 CDI 4 – I often no longer have the patience to listen to them 5.5 ± 2.8 0.62 0.85 0.75  
 CDI 10 – I increasingly ‘work to rule’ 5.2 ± 3.1 0.61 0.85 0.70  
 CDI 9 – I myself increasingly go short 6.1 ± 3.3 0.67 0.84 0.68 0.36
 CDI 7 – I increasingly think how nice it would be to pack it all in 5.0 ± 3.2 0.62 0.85 0.65 0.33
 CDI 5 – I largely don’t care what they think of me 4.0 ± 2.5 0.44 0.86 0.54  
Factor 2: Emotional withdrawal as strategy (eigenvalue: 1.0; 26% explained variance)
 CDI 1 – I simply must stop letting everything get to me to such an extent 6.0 ± 3.0 0.57 0.85   0.88
 CDI 2 – I have to withdraw with increasing frequency to protect myself 5.6 ± 3.0 0.64 0.85   0.85
 CDI 3 – their personal problems and worries often simply become too much for me 4.8 ± 2.7 0.60 0.85 0.38 0.65
