In this workshop we will explore ‘developmental trauma’, and how this can show up in our clients. We will use the ‘undeveloped self model’ (Hargaden and Sills, 2002; pg 25), as a key way of plotting trauma in a 3rd order structure.
We will also explore how this can be used alongside other TA models such as Trautmann & Erskine’s ‘Relation Needs’ (1996), Lee’s (1998) ‘The Drowning Person’, and O'Reilly-Knapp & Erskine’s ‘Script System’ (2003), to support treatment direction.
We will explore how child development (Thunnissen, 1998) can be mapped onto ego state development, and how trauma and impact on this growth. Throughout this workshop we will be considering how we can use this model in our client work.
