In the text:
Baim argues that "understanding adult attachment patterns can also help practitioners to more readily identify the behaviour patterns that the client uses to maintain safety and comfort and which also, in some cases, serve to keep the client stuck in behaviour that no longer serves them as adults". (Baim, 2015)
