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