Thousands of practitioners using prior editions of the DSM have relied on this key resource to optimize their diagnostic practices in PreK-12 settings. Now significantly revised for DSM-5, the book cuts through the overwhelming length and complexity of the diagnostic manual by focusing thematically on the most common child and adolescent concerns. Tips are provided for diagnostic decision making and coding, and technical terms are demystified. Emphasis is given to using diagnosis as a foundation for effective intervention.
