DSM-5 reconceptualizes psychological disorders as both lifespan disorders and spectrum disorders. As such, age of onset has been eliminated for most disorders and diagnostic criteria now reflect a range of clinical presentations across the lifespan. In this same context, juvenile forms of some disorders (PTSD, psychosis, depression) have been developed. To capture a range of clinical presentations along a spectrum, all diagnoses include severity scales, “subsyndromal” conditions have been identified, and cultural diversity considerations have been added to reduce stigma and minimize the likelihood of pathologizing clients. In order to identify early interventions and make treatment planning reflective of a range of clinical presentations, some diagnoses have been revised (e.g., substance abuse and dependence subsumed into a single diagnosis), newly developed (e.g., Hoarding Disorder), and eliminated (e.g., Asperger’s Disorder). Finally, new classifications have been added (e.g., Trauma- and Stressor-Related Disorders) to help assessment and treatment protocols fit with current research.
The DSM-5 textbook features categories and accompanying diagnoses charts, study focus questions, 13 diagnostic practice vignettes, and easy-to-navigate summaries of diagnostic criteria.
