I found the book to be slightly outdated. I would, at minimum, conduct a search of other books on the same topic before purchasing this one.
Clinical documentation is critical for mental health professionals. This book is the best I've read on this topic. It discusses elements that need to be in the progress notes of a mental health professionals, and different formats for doing progress notes. It is a guide that is practical and legally savvy. I highly recommend this book for mental health professionals at all levels of experience. It is a resource that I refer to frequently in my work.
