Abstract: Many books, chapters, and articles concerning the assessment and treatment of the paraphilias have been published. Most are limited due to a lack of clarity about what is being treated and a failure to fully recognize the heterogeneity of the treatment population(s). This chapter provides a review of the assessment methods and treatments that have been recommended for paraphilic disorders in general. They are presented together because assessments and treatments can be generalized across different paraphilic disorders and many assessment and treatment approaches are complementary. Treatment approaches specific to individual paraphilias are discussed in the chapters dealing with the specific paraphilias.
