The publication of the Diagnostic and Statistical Manual Version 5 (DSM-5, 2013) and the more recent Diagnostic and Statistical Manual Version 5 - Text Revision edition (DSM-5-TR, 2022), together ushered in a major change to the field of mental health diagnosis. DSM-5-TR Insanely Simplified provides a summary of key concepts of the new diagnostic schema introduced in DSM-5 as well as the updated DSM-5-TR. It utilizes a variety of techniques to help clinicians master the new spectrum approach to diagnosis and its complex criteria. Cartoons, mnemonic devices, and summary tables allow clinicians and students to quickly grasp and retain broad concepts and subtle nuances related to psychiatric diagnosis. DSM-5-TR Insanely Simplified fosters quick mastery of the most important concepts introduced in DSM-5 and continued in DSM-5-TR, while offering an entirely new way of looking at mental health along a continuum. This new approach goes beyond simply "labeling" clients with various diagnoses, but rather places them along spectrums that range from normal to problematic symptoms. Mental health professionals and laypeople will appreciate the synthesis of deep psychology and modern approaches to the diagnosis of mental illness.
