The Revised Screening Scale for Pedophilic Interests: Predictive and Concurrent Validity
Published online on December 16, 2015
Abstract
This study examined the predictive and concurrent validity of the Screening Scale for Pedophilic Interests (SSPI) and its recent revision (SSPI-2), using a large sample of 2,416 sex offenders deemed not to be in need of civil management in New York State. Both SSPI and SSPI-2 scores were significantly and positively related to sexual rearrest, but the SSPI-2 provided greater discrimination in rearrest within 5 years across possible scores. Neither measure significantly added to the prediction of sexual rearrest provided by the Static-99R. We also found evidence of concurrent validity, as both measures were positively and significantly correlated with clinician ratings of sexual preoccupation, emotional identification with children, and sexual offense–related cognitions (convergent validity), but were not significantly related to clinician ratings of self-regulation problems, noncompliance with supervision, or antisocial personality (divergent validity). Overall, the results suggest that the SSPI-2 is a specific and useful screening measure of pedophilic sexual interests among sex offenders with child victims.
