This was an impulse buy as I needed it for my current job and it's been well worth it.
Very clear easy descriptions of the common mental health issues handled by health workers in general.
As a reference, I've been able to work through most of the book in a few short hours and make sense of it. Someone training for the role would find this very quick and straight forward.
Of course, whilst reading it, it's the kind of book that might have you looking at people you know in a new way for a short time. That's temporary, once you've decided that your best made is borderline or your boss has OCD :).
Worth having if these issues are something you are training to deal with at a nursing and day to day care level. It covers interviewing and interaction, general care issues then delves into mood disorders, personality disorders, drug and alcohol abuse and more. It takes care to dig a little deeper, for example bipolar disorder is broken down into Type 1, Type 2 and cyclothemic as well as discussing rapid cycling. These are all described in some detail and DSM-IV extracts are used to elucidate how diagnosis would be reached. This is a nursing care level book and takes practical bullet pointed approaches rather than lots of theory. Treatment and communications issues in different cases are carefully laid out.
Possibly one of my best sudden impulse book buys this year.
