The possibility of a systematic exchange, a meeting "on equal terms," between individuals affected by borderline personality disorder, their relatives, and professionals was long considered unfeasible. It was said that the communication and relationships between the groups were too influenced by intense emotions. Fortunately for all involved, the initiative for a borderline trialogue was nevertheless undertaken. Anja Link, one of the co-initiators, and Dr. Michael Armbrust, an expert in the treatment of personality disorders, illuminate borderline in this book from all three perspectives: According to the trialogue concept, it is shown how affected individuals, relatives, and professionals can learn from and benefit from each other through mutual exchange. The authors address the typical problems and challenges in their interactions, propose solutions, and thereby create a greater understanding.
