Mark F. Lenzenweger provides a well-written and extensive overview of schizotypy and its relation to schizophrenia. The author notes that the book is targeted toward advanced undergraduate and graduate students in psychological sciences. However, I found it to be an excellent compilation of the research in schizotypy and the nature of its continuum with schizophrenia. The book is sprinkled with clinical examples of the concepts that caused me to reflect on patients who I have treated in the past. For example, in one case the author raises the role of social anxiety in the schizotypy phenotype. I remember several patients who were referred from an anxiety disorders program to my youth psychosis program because they did not seem to fit the anxiety disorder mold. They did not have psychosis but rather a pronounced anxiety with social encounters coupled with oddities in behavior. Such patients fall into the schizotypy phenotype. Indeed, Lenzenweger makes the comment that "nearly all of the research vectors that I have pursued in the laboratory have begun as clinical observations" (p. 24). Thus, while heavily weighted toward research design and analysis, the book also encompasses clinical relevance. It is a book that is not only for students of psychological sciences but can also serve as interesting reading for psychiatric residents and interested clinicians who desire a thorough review on the topic, including research design, methods, and interpretation.
