Radically Open Dialectical Behavior Therapy (RO-DBT) addresses maladaptive overcontrol seen in perfectionism, chronic depression, anorexia, treatment-resistant anxiety, and Cluster C disorders. Though DBT is widely used, RO-DBT is less applied in groups despite strong evidence. This session introduces overcontrol theory, social signaling, and RO-DBT’s group model, highlighting how groups foster flexibility, openness, and connection. Attendees gain practical skills, strategies for managing OC clients, and tools for immediate clinical use.
