Obsessive compulsive disorders can take many forms, as this book acknowledges. Indeed, the object of obsession/ compulsion often seems arbitrary - compulsion is a drive which can "cathect" (to employ psychoanalytic jargon) almost anything. I found the book useful in addressing the problem of obsessional letter writing and the attendant gratification of seeing one's name in print. I came to realise that this was in fact a symptom of something that it is not the place of this review to divulge. However, this book is not in itself enough and readers would be advised to read it in conjunction with therapy.
