Process-based Behavior Therapy (PBBT®) is a scientifically-based psychotherapy. PBBT works by fundamentally changing the relationship we have with ourselves and redirecting our behavior towards a more meaningful life.
The therapy was developed by the founders of Perspectives Ireland, Dr. Yvonne Barnes-Holmes and Dr. Ciara McEnteggart, after years of research on human behavior and practice in clinical psychology.
As academics, we worked for many years on trying to advance the basic science of human behavior in order to connect it to psychotherapy and mental health problems.
Our scientific discoveries led us to understand the core elements of mental health and enabled us to build a science-based programme of psychotherapy, called PBBT. It could be argued that a psychotherapy built directly from scientific principles is the first of its kind in the field of clinical psychology.
We meet mental health professionals from all contexts who are deeply dissatisfied with existing psychotherapies and the client outcomes these produce. And research suggests that poor clinical outcomes are directly associated with increased levels of burnout and risk of leaving the profession.
