This one-day training workshop is designed to support psychotherapists in their work with clients or patients who are on the self-harming spectrum from minor self-injury to suicide. Led by Dr Maggie Turp, author of Hidden Self-Harm: narratives from psychotherapy, we will be introduced to the concept of self-harm, its aetiology and function. We will explore the continuum model of self-harming behaviour, its roots in infancy, and be introduced to the concept of 'psychic skin functioning' - a way of thinking about self-harm as damage to boundaries around the self. We will link findings from infant observation to findings from neurobiology to help us understand why some people self-harm. Finally, we will fine-tune our capacity to identify, understand and address dependency issues in clinical work.
