START is a small NGO based in Christchurch, New Zealand that has worked for 31 years with children, youth and adults who have experienced sexual violence. Trauma is at the heart of the work we do with clients and so to be ‘trauma informed’ is essential. Although this term is now common place, when our team was challenged around what it actually meant to us and for the clients within our service, the answers suggested that ‘trauma informed practice’ might well mean different things for different people. This started a conversation that ended in the development of a clinical practice model. The aim was to create a model that provides enough scaffolding to guide clinicians as well as inform clients about the work they are doing, while not being so prescriptive that individual influences and needs are disregarded. The result is the’ START Clinical Model’ which places trauma processing work in a context of the world the client lives in, the therapeutic relationship the work occurs in, and the service related factors that facilitate this work to take place. This has not been an academic exercise, but one born out of clinical need and experience that has factored in social, family/whanau and individual influences and considerations. As a result, this seminar is not an academic one, but one that looks at the practicalities of working with a sexually harmed client group in a way that is informed by our knowledge of trauma. START’s model was designed to be relevant for all age groups, however we will be focusing more specifically on its utility with children and youth in the examples we discuss.
