The initial study sample consisted of persons listed on the Ontario Sex Offender Registry (Canada) who had ever been convicted for the possession, distribution, or production of child pornography since the inception of the registry in April 2001. Nonviolent offenses consisted of a charge or conviction for offenses that did not involve direct contact with a person. Child pornography and noncontact sexual offenses were also counted in this category. Two-thirds of the subjects (n=135) had only child pornography index offenses; the remainder were convicted of other kinds of offenses at the time they were adjudicated for a child pornography offense. Thirty-four offenders (17 percent) offended again during the follow-up period, an average of 2.5 years. Four percent committed a new contact sexual offense. Child pornography offenders with prior criminal records were significantly more likely to reoffend in any way during the follow-up period. Child pornography offenders who had committed a prior or concurrent contact sexual offense were the most likely to reoffend, either generally or sexually. 3 tables and 19 references
