Fully updated in line with the DSM-5 Text Revision (DSM-5-TR), this trusted resource addresses how to diagnose frequently encountered child and adolescent problems in school-based mental health practice. The expert authors cut through the overwhelming length and complexity of the DSM by focusing thematically on prominent presenting symptoms, such as learning problems, anxiety, or disruptive behavior. The book addresses new diagnostic criteria and categories in DSM-5-TR, identifies changes from prior versions of the DSM, and discusses implications of DSM-5-TR diagnoses for special education eligibility under IDEA. Tips are provided for diagnostic decision making and coding, and technical terms are demystified.
