Sex offenders constitute a heterogeneous group of individuals. The term sex offender describes one who has committed any of a variety of offenses, including rape, child sexual abuse, possession of child pornography, exhibitionism (flashing), and even consensual sex among teenagers. Sexual offenders can be adults or juveniles, male or female, and the perpetrators may be strangers, acquaintances, or related to their victims. These offenders have different characteristics and motivations for committing their offenses, and as such, differing responses are appropriate in order to accurately treat, manage, and supervise them. This research paper will review types of offenses and offenders; the prevalence of sexual abuse and recidivism; and responses to sexual offending, including treatment, supervision, and management practices for this population.
