Overview

A look at the data and results of an August 2022 study of 141 sexual offenders. The study further emphasizes the recidivism prediction abilities of the CPORT.

Summary

Evaluators conducting evaluations and risk assessments CSAM offenders do not have a validated actuarial risk assessment measure for this population. For contact offenses, there are several, with the Static-99R being the most widely used.

To combat this, Seto and colleagues created the CPORT. 

However, the CPORT authors provide the following provisos:

  • It should not be used with more than 1 missing data point
  • Until it has been validated more widely, should not be used as a measure to predict recidivism

The CPORT Validation Study

This study, published in August of 2022, sought to directly replicate the original CPORT validation study with a population of individuals from Scotland. They were charged with offenses related to images of child sexual abuse.

The authors were able to use data for 141 individuals with a fixed follow up period to measure recidivism of 5 years.
