elve into the complex realm of addiction as this study explores the underutilized attachment framework within couples therapy, specifically through the lens of Intensive Short-Term Dynamic Psychotherapy (ISTDP). Addiction, a pervasive mental health issue with profound implications for relationships, has often been approached through short-term, symptom-focused treatments. However, high rates of relapse and the emergence of cross-addictions indicate a need for a more comprehensive understanding and treatment. The study draws on the experiences of ISTDP couples therapists who view addiction as a defense rooted in insecure attachment bonds. While the popular medical model tends to prioritize individual treatment and short-term symptom management, this research investigates the potential of fostering secure attachments in couples therapy to address the root causes of addiction.
