The question we want to address in this part of the book concerns the conclusions that can be drawn from the observations in the first part for therapeutic work. What can be worked on? How should work be done? What can be considered effective in analytical group psychotherapies? Many explanations and examples will follow in the next chapters. If it was difficult relationships and group experiences in the past that have had a shaping and inhibiting effect on development, how can new group experiences connect to this, how can the unpleasant experience of repeating traumatic experiences be avoided? And where does the assumption come from that we all carry a need for trustful attachment within us? We want to emphasize the resource orientation in everything, a commonality of Analytical Psychology, contemporary trauma therapy, and modern behavior therapy, as well as, I think, also in the work in groups, as long as their effectiveness is fed by factors that can be particularly effective in groups, but only under certain conditions can unfold. In the end, the conclusion is: Groups work well because our entire lives as humans take place in groups.
