This online course will discuss the dominant paradigm for ‘parts’ work in EMDR therapy and examine a well-established but lesser acknowledged ‘parts’ approach; explore the potential challenges of predominately focusing on the priorities and needs of a ‘front’ part to the exclusion of the other self-states; discuss the use of ‘mapping’ of self-states and its potential value in the context of EMDR therapy; and finally delve into different manifestations of ‘classic’ post-traumatic flashbacks that are more easily understood through the lens of the self-system as a multidimensional construct.
