The Child Pornography Offender Risk Tool (CPORT) is a seven-item actuarial risk assessment tool that is used to estimate the potential for sexual recidivism among men convicted of child sexual exploitation material (CSEM; legally referred to as child pornography) offenses. In the current study, we examined the convergent and divergent validity of the CPORT in a clinical sample of 224 men on federal probation in the United States who were convicted of at least one type of CSEM offense. CPORT scores were significantly, moderately, and positively correlated with scores on another sexual offense risk assessment tool, the Risk Matrix 2000 (RM2000/S), showing broad evidence of convergent validity, and was nonsignificantly associated with scores on a general offense risk assessment tool, the Level of Service/Case Management Inventory (LS/CMI), showing evidence of divergent validity. There was also evidence of specific convergent validity; for example, the CPORT item reflecting prior criminal history was most strongly related to the Criminal History domain of the LS/CMI, and CPORT items reflecting sexual interest in children were significantly and strongly associated with self-reported sexual interest in children from the clinical evaluation. We also examined the impact of including clinical information in the scoring of the CPORT. Including this information reduced the amount of missing scores, but the impact on predictive accuracy is not yet known. Implications for clinical practices are discussed.
