Radically Open Dialectical Behavior Therapy (RO DBT)

Radically Open Dialectical Behavior Therapy (RO DBT) is a form of cognitive behavioral therapy developed by Thomas R. Lynch for the treatment of disorders characterized by excessive self-control, referred to as “overcontrol.” This coping style is associated with emotional inhibition, perfectionism, rigidity, and social isolation. RO-DBT is conceptually distinct from standard dialectical behavior therapy (DBT), which Marsha M. Linehan developed to address uncontrolled behaviors such as impulsivity and emotional dysregulation. RO-DBT is primarily used in the treatment of conditions such as treatment-resistant depression, anorexia nervosa, obsessive–compulsive personality disorder (OCPD), and certain autism spectrum presentations. It is based on the premise that excessive self-control can impair social connectedness and psychological well-being.

RO DBT was developed over more than two decades by Thomas R. Lynch. Early research focused on adapting standard DBT for older adults with chronic depression and comorbid personality disorders. This work identified a subgroup of patients who did not respond well to traditional cognitive and behavioral therapies, displaying high levels of emotional inhibition, social withdrawal, and rigidity rather than impulsivity. The treatment model was formalized in 2018 with the publication of Lynch’s two-volume clinical manual, Radically Open Dialectical Behavior Therapy: Theory and Practice for Treating Disorders of Overcontrol.

RO DBT integrates behavioral, neurobiological, and evolutionary perspectives within its theoretical framework. The model proposes that overcontrol is associated with heightened threat sensitivity, reduced reward sensitivity, increased inhibitory control, and a detail-focused style of cognitive processing.

A central concept in RO-DBT is that emotional expression serves as a social signal that facilitates interpersonal connection. Suppressed, exaggerated, or incongruent emotional signaling is associated with loneliness and psychopathology. The therapy emphasizes improving authentic emotional expression to strengthen social bonds. Social Signalling is considered a primary mechanism of change in RO-DBT.

“Radical openness” refers to a willingness to question one’s beliefs, remain receptive to feedback, and engage with novel or uncertain experiences. This concept is considered a core mechanism of change in RO-DBT.
