The book is composed of several chapters on various forms of sexual deviance, including exhibitionism, fetishism, frotteurism, pedophilia, sexual sadism and masochism, voyeurism, rape, and transvestic fetishism. What is significant about the book is the separation of each of those conditions into a chapter on psychopathology and theory and a separate chapter on assessment and treatment. That distinction is helpful to the researcher and clinician who requires information about a patient or a condition that is being researched.
