    ""Assessing Psychosis" is an essential read for clinicians and students alike, offering a comprehensive and nuanced approach to understanding and evaluating psychotic phenomena.

    "Khadivi and Kleiger have updated their excellent guide written for a wide range of clinicians on assessing psychotic symptoms. Broad in scope, their book emphasizes using interviewing; psychological tests; and rating skills in this assessment. Among its many valuable insights, the book helps us avoid the many false binaries that bedevil our assumptions about psychosis."

    “This updated version of a very valuable resource continues to help me conceptualize the complexities of psychosis. The clinical assessment points that encapsulate each chapter are easy to access and beneficial in emphasizing key points. The assessment of suicidal risk in psychosis is particularly relevant to my clinical practice.”

    Margaret Bookman, RXN, CNS, APRN, Certified Psychiatric Clinical Nurse Specialist

     “This greatly enlarged, indispensable 2nd edition of Assessing Psychosis provides encyclopedic coverage of this pervasive and compelling clinical entity. Comprehensive, lucid treatment of the subject matter covers clinical features, diagnostic concepts, assessment methodologies, special populations   (psychosis in children and adolescents),  psychosis in culture with ample case material. The revision greatly benefits from new and expanded chapters on differentiating delusions from extreme radicalization, subclinical psychosis in the general population, forensic assessment, and violence and suicide risk in psychosis.  The authors show that psychosis is not limited to the clinic, but a pervasive dimension of human existence.”
