This second edition of Assessing Psychosis: A Clinician's Guide offers both a practical guide and rich clinical resource for a broad audience of mental health practitioners seeking to sharpen their understanding of diagnostic issues, clinical concepts, and assessment methods that aid in detecting the presence of psychotic phenomena. Case vignettes deepen clinical understanding, and all chapters include a summary of practical clinical guidelines. This new edition includes two new chapters and updated diagnostic criteria considering the new DSM-5-TR. Practicing psychiatrists, psychologists, social workers, psychiatric nurses and students will find this a valuable resource for clinical practice, training, and teaching purposes.
