3This second edition of Michael Seto's authoritative book summarizes and integrates advances in the scientific understanding of pedophilia and sexual offending against children. Seto provides a thorough yet accessible synthesis of current research, identifying the psychological and biological underpinnings of pedophilia. He translates this research into practical recommendations for clinical evaluation, risk assessment, and intervention. New to this edition are an increased emphasis on prevention efforts with at-risk individuals, and a clearer distinction between pedophilia and other forms of paraphilia---primarily hebephilia.
