Emotional Dysregulation, Maladaptive Overcontrol in Anorexia - Effect of Radically Open Dialectical Behaviour Therapy

This clinical trial employs a two-fold approach, utilizing a single-arm feasibility design within a larger multiple baseline experimental case series study framework over 32 weeks. The study aims to investigate both the feasibility and efficacy of Radically Open Dialectical Behaviour Therapy (RO-DBT) in patients with anorexia nervosa (AN). Feasibility will be assessed through treatment retention, data collection engagement, patient satisfaction, and the occurrence of adverse events. Efficacy outcomes will focus on RO-DBT's impact on ED psychopathology, obsessive-compulsive personality traits, EDR, and BMI.
