The document provides an overview of the DSM-5's treatment planning process, emphasizing a client-centered approach that incorporates diagnosis, assessment, and collaboration between clinician and client. Key updates include the abandonment of the GAF scale in favor of the WHODAS 2.0, changes in coding systems, and a focus on severity specifiers for diagnoses.
