19 General introduction Based on the overall aim of DCIA – to further stimulate the moral craftsmanship of their staff – we aim to research whether MCD sessions influence the moral craftsmanship of prison staff. We wish to add insights about the value of MCD to present literature, since quantitative data about the impact of MCD are not yet common. Furthermore, the concept of moral craftsmanship is not well-studied and defined yet. We therefore wanted to describe the concept of moral craftsmanship in order to better understand what moral craftsmanship in the context of prison work means and which components it entails when measuring moral craftsmanship. With the description of the concept of moral craftsmanship, we aimed at developing a first questionnaire to measure components of moral craftsmanship. By this, we wish to operationalize the concept of moral craftsmanship in the context of prison work. To improve insights on what the MCD sessions offer prison staff, lastly, we aim to analyze what prison staff themselves mention as experienced outcomes of MCD sessions. In addition, we want to know in which way these experienced MCD outcomes are related to a potential moral learning process of prison staff. The overall aim of this thesis is to assess the value of MCD in the context of working in prisons. The aims mentioned above resulted in the following research questions (RQ): 1. Content of MCD: What are the themes of the moral dilemmas discussed during MCD sessions with prison staff? 2. Evaluation of MCD: How do prison staff and their MCD facilitators experience single MCD sessions and the series of MCD sessions? 3. Meaning and measurement of Moral Craftsmanship: What does the concept of moral craftsmanship entail in prison work, and how is this to be operationalized into a questionnaire? 4. Impact of MCD on Moral Craftsmanship: What is the impact of participating in a series of MCD sessions on the moral craftsmanship of prison staff? 5. Outcomes of MCD: What are the outcomes of MCD as mentioned by participating prison staff and their facilitators, and how does this relate to a moral learning process of participants by MCD? 1
