Investigating mobility patterns for repetitive sexual contact in adult child sex offending

In the present study, geographic mobility exhibited by child sex offenders was examined. Geographic mobility was defined as the use of multiple locations to obtain repetitive sexual contact with the same victim. The sample consisted of 77 adult offenders convicted for having committed a sexual offence against a child, and who agreed to provide confidential self-report data concerning their offending behaviours. Based on a set of offence characteristics, offenders who used a single location were compared to offenders who used multiple locations for sexual contact. Results showed that offenders who used multiple locations are more likely to isolate the victim, use violence, involve the victim in several sexual episodes, abuse the victim for a period exceeding one year, and make the victim participate and perform sexual behaviours on them during sexual episodes. Examining more closely offenders who used multiple locations for abuse, three offence patterns were further identified (i.e., familial-low mobility offence, non familial-high mobility offence, and familial-high mobility offence). Going for a car ride was also found to be a common location/situation used in the familial-low mobility offence subgroup, while the use of outdoor locations on a regular basis was found to be rare in high mobility patterns subgroups.
