Section 3.1 already briefly mentioned the early childhood developmental phases, which will be described in more detail below. Individual character structures arise from inadequately resolved conflicts during these phases. In contrast to the concept of character structures, which goes back to Freud (1908), Rudolf (1993) and others refer to structures that are more indicative of the developmental stage and the good, moderate, poor, or disorganized level of integration of a personality. This sometimes leads to a certain confusion regarding the concept of structure. Here, I refer to the former concept of character structures.
