Short-Term Psychodynamic Psychotherapy

ISTDP is a form of accelerated treatment which enables positive change and recovery within shortened time-frames. Research evidence shows that ISTDP is effective and cost effective with a multiplicity of clinical presentations. Clinical practice in the method continues to evolve along with a need to identify clinical techniques and therapeutic mechanisms that are essential for effectiveness, change and positive outcome. Speakers will present their perspectives on the ‘main ingredients’ of ISTDP illustrated through clinical video extracts of their own practice. The immersion will be a forum to illuminate and discuss similarities, divergences and nuances in clinical technique and applications. The aim is to stimulate a productive and informative examination of various aspects used in ISTDP and to distil and highlight critical components required for change.
