Abstract
The present paper introduces a theoretical model that addresses the interplay between insecure attachment, internal narratives, and defensive behaviour. Drawing from attachment theory research, we conceptualize the “internalized defensive narrative” (IDN) as a mental representation associated with attachment-insecurity. The model illustrates how the unique IDN associated with attachment-anxiety and attachment-avoidance respectively invoke hyperactivating and deactivating defenses. In clinical contexts, the model’s application may possibly contribute to the development of more effective therapeutic strategies that target the root causes of a client’s defensive behaviour. By recognizing the IDN as a key factor in the maintenance of the insecure cycle, therapists can potentially help clients gain insights into the psychological mechanisms driving their behaviour and provide them with tools for change, leading to improved therapeutic outcomes for individuals struggling with these issues. Further research is needed to validate and elaborate on the proposed model and its implications for clinical practice.
