Overall RRP mean score was computed as the average score on the 11 RRPs with the not applicable scores recoded to 1 (i.e. never). Model containing the five background variables (see Table 2a) and all 10 explanatory factor scales.

^*Two subscales (Distributional and Procedural Organizational Justice) were merged due to high correlation. Extended data: Table 4 shows the correlation of all the explanatory factor scales. Bold figures are statistically significant.
