Project Description

The ISTDP London core training is an IEDTA certified programme that trains clinicians in ISTDP theory and psychotherapy skills. This programme has been designed in consultation with Dr Robert Neborsky, MD, who has developed the attachment-based ISTDP model and there is an emphasis on Attachment Based-ISTDP techniques.

Areas covered in the syllabus include:

  • Metapsychology of ISTDP
  • Key therapeutic interventions
  • The diagnostic spectrum and assessment process
  • Working effectively with unconscious anxiety & maladaptive defence processes
  • The punitive superego
  • The Central Dynamic Sequence

Lectures and clinical presentations are used to teach key concepts and techniques.

Supervision of participants’ own clinical work is a key element of the programme and trainees are required to present video of their work in progress.


To be eligible, participants must be qualified mental health professionals registered with a professional body (eg: psychotherapists, psychologists, psychiatrists or counsellors). Trainees registered in an accredited training programme may also be considered for enrolment. The programme is suitable for clinicians working in NHS as well as private settings.

A small group format is designed to create a safe and stimulating environment for trainees. Full duration of the core training programme is 3 years, but commitment to one year’s training at a time is required. Acceptance into the following year will be by mutual agreement.

The lead trainer is Dr Sharon Lewis, a chartered clinical psychologist registered with the British Psychological Society and the Health Professions Council in the UK. She is an accredited IEDTA supervisor and trainer and has extensive experience in offering core training programmes in ISTDP, as well as introductory and advanced training.  Dr Robert Neborsky ( will provide additional teaching and supervision, and experienced ISTDP colleagues may be invited to contribute on specialist topics.
