128 Chapter 5 Differences in impact between professional disciplines There were a number of clear differences between the general scores on elements of MCS between pre- and post-measurement and between the scores per discipline. We discuss interesting differences for the disciplines on items that did not show differences in the main analysis. For one item, ‘knowing the personal values and norms of my immediate colleagues’, we saw more positive progress in a specific discipline: ‘office staff re-integration services’ scored considerably higher in the post-measurement (87%) compared to the pre-measurement (71%). For the other professional disciplines this item remained more or less the same. We also saw that, after attending the MCD sessions, health care professionals scored lower with regard to ‘wondering whether they’re doing the right thing during work’ and correctional officers scored lower on ‘deviating from agreements and protocols when they feel it is right to do so’. ‘Office staff re-integration services’ indicate at post-measurement that there is less ‘attention to why they make certain decisions in their team’ and that ‘during work, they as a team ask themselves whether they are doing the right thing’. Differences in impact between the number of MCD sessions attended Data on the number of MCD sessions attended by participants, and how they experienced and evaluated them, was available for the intervention group in the post-measurement. We divided the number of MCD sessions attended into 3 categories: 1-3, 4-6 and 7+ times participation in MCD sessions (Appendix 9). This subgroup analysis shows that on three items the group that participated 4 to 6 times (n=50/156) in MCD sessions showed a larger difference between pre- and post-measurement than the group that participated in 1 to 3 MCD sessions. These items were: ‘How often do moments occur in your work in which you are uncertain of the right action to take?’, ‘I know the personal values and norms of my immediate colleagues’ and ‘At work we are given tools to deal with moral dilemmas’. However, this larger difference did not remain or increase with 7+ MCD sessions. The group that attended the most MCD sessions did not always show the largest difference on the items. Thus, attending more MCD sessions does not necessarily lead to a greater impact on MCS. Differences in impact based on different evaluations of MCD In the evaluations of MCD, 17% of the participants scored (very) negative and 43% scored (very) positive (Appendix 10). Furthermore, in the scores for the MCS items, split according to the evaluation of MCD by prison staff (positive-negative), we found
