Descriptive statistics and coefficient of internal consistency for the organisational culture scales, n=1406 survey responders
| Organisation culture scale | Median (IQR) | Range (low to high) | Mean (SD) | Cronbach alpha* |
| Group | 25.0 (13.3 to 38.3) | 0 to 100 | 27.2 (17.8) | 0.81 |
| Developmental | 15.8 (9.2 to 21.7) | 0 to 66 | 15.9 (9.6) | 0.54 |
| Hierarchical | 29.2 (17.5 to 43.3) | 0 to 100 | 32.6 (19.3) | 0.72 |
| Rational | 23.3 (16.7 to 30.0) | 0 to 92 | 24.3 (11.9) | 0.44 |
Each scale has five items (see online appendix).
↵* Cronbach alpha is a psychometric statistic measuring the consistency of the correlations between the survey items and the overall scale. An internal consistency greater than 0.70 is adequate when using a scale for group comparisons.22
