A meta-analysis of nine studies conducted by Seto in 2011 reported a sexual recidivism rate of 5% for follow-up periods ranging from one to six years. Another paper published by Seto in 2015 reported a sexual recidivism rate of 11% in a 5-year follow-up period. Research has also shown that offenders that measure high on antisociality and atypical sexual interests are most likely to sexually reoffend.[11] Other studies have also reported rates of recidivism for child pornography offenders that are inferior to those of contact child sex offenders. People who have committed both pornography and contact offences have a higher recidivism rate for contact offences than child pornography offenders.[55]
