Forensic psychiatrists frequently deal with deceptive people. In these cases, malingering is the most common type of deception one encounters. However, deception on the part of mental health clients in other treatment settings is much broader and more complex than malingering, and learning the signs of deception can be useful for therapists in any specialty, especially those who do not necessarily take what their clients tell them at face value.

The book begins with an introduction to some basic concepts concerning deception, with particular emphasis on “what it is” and “what it isn’t.” It then looks at the motivations behind and methods of deception in mental health practice, as well as the common contexts in which deception occurs. Finally, with an eye toward the detection of deception, the book looks at the game of poker as a “clinical case study” to explore whether the popular notion of “tells” has any relevance to the practice of mental health treatment.

This short and uniquely illustrated guide will help mental health professionals determine when, why, and how their clients may lie to them. With some of the analysis based on insights from the world of poker players, readers will learn about methods of deception, reasons why clients deceive them, and the best methods to uncover the truth.
