In this presentation, forensic psychologist Dr. Jeff Kelsesky explains the scientific and clinical frameworks used to understand different types of sex offenders. He emphasizes that sex offenders are not a homogeneous group and discusses three broad categories: offenders who target adults, offenders who target children, and offenders whose crimes are associated with paraphilias or fetishes. The presentation explores distinctions between violent and nonviolent offenders, the role of authority and power in sexual abuse, the differences between pedophilia and ephebophilia, and the importance of factors such as victim age, grooming behavior, and prior relationships in determining risk. Dr. Kelsesky also discusses how forensic psychologists use research-based assessments to evaluate treatment responsiveness and the likelihood of reoffending. Throughout the discussion, he stresses the importance of approaching the topic with scientific accuracy while recognizing the profound and lasting impact that sexual abuse has on survivors.
