The most refreshing aspect of this book includes the colloquial writing style of the author, who ironically disarms the reader while explaining how to disarm patients. The first three chapters in section 1 review the psychiatric diagnostic interview in detail, from the importance of body language to specific questions to ask during the 30-minute interview. While a bit rudimentary for the seasoned practitioner, the section gains momentum by discussing critical changes to DSM, including the introduction of the dimensional analysis of psychiatric symptoms. Through the use of four common case presentations—for major depressive disorder, schizophrenia, alcohol use disorder, and narcissistic personality disorder—the author illustrates the utility of removing confusing subtypes and qualifiers, which is a reflection of the changes exhibited in DSM-5. In one compelling vignette about major depressive disorder, Nussbaum discusses a patient named “Ruth” who struggles with the recent death of her husband of 30 years. He explains that “she has been hearing the voice of her deceased husband telling her that he misses her,” illustrating the depth of loss this patient feels. In taking the reader on this journey, he demonstrates how this patient meets criteria for major depressive disorder according to DSM-5, since the bereavement exclusion has been removed. Furthermore, he demonstrates how the specifiers are different for her diagnosis in DSM-5 because she can have psychotic features (hearing her husband speak to her), but they are now classified as moderate, not automatically severe, considering her ability to maintain work and care for her family.
