I bought this book on the basis of the description above hoping that it would be helpful to the social workers, teachers and foster carers that I work with. However it is disappointing and frustrating, and I can't recommend it.
Astonishingly it does not define 'Disorganized Attachment', and seems unable to decide whether this is a characteristic of personality organisation, or simply a set of behaviors which can be observed in specific contexts. The authors are critical of the widely accepted formulation of Reactive Attachment Disorder, which they argue has not been subjected to rigorous analysis and research, (unlike Disorganised Attachment, they say) and yet they refer constantly to the three organised Attachment styles (Secure/Ambivalent/Avoidant)that RAD differentiates. They state that Disorganised Attachment is not an Attachment style, and can only be observed for short periods before it resolves into one of the organised styles, but then suggest they would expect it to be constant over time, and discuss the characteristics of DA in adolescents, and the implications for adult mental health.
The book lacks a clear narrative, and the tone shifts from detailed descriptions of research methodology to theoretical formulation to folksy anecdotes, descriptions of brain imaging equipment which might have been lifted from a patient's information leaflet, and pompous descriptions of the level of training needed to diagnose attachment styles. In places the grammar and syntax lack precision, rendering paragraphs impossible to decipher, and in places passages are repeated. The authors are experienced and knowledgeable, but the lack of a good editor is woefully evident.
To be fair I should admit that I read only the first half of the book, before deciding that I could probably make better use of my time. I did dip into the second half, in case it improved, but found no evidence to encourage me further.
I had hoped to arrive at a better understanding of Disorganized Attachment, which is probably a helpful formulation for many of the children with whom I work, but I am, I'm afraid, no clearer as a result of trying to engage with this book.
