Validating the Screening Scale of Pedophilic Crime Scene Behavior

Abstract

The Screening Scale of Pedophilic Crime Scene Behavior (SSPC) is a seven-item structured rating scale assessing pedophilic sexual arousal. In the current study, we cross-validated the scale’s convergent validity using multiple measures of sexual interest in children (clinical diagnosis of pedophilia, the high fixation/low social competence type of the MTC:CM4, and phallometric assessment of sexual interests toward children) in two independent samples (USA and Canada). In both samples and in relation to all three criteria, the SSPC showed acceptable (phallometry) to excellent (clinical assessment) diagnostic accuracy. Furthermore, the SSPC showed incremental validity in relation to the Screening Scale for Pedophilic Interest and at times outperformed it in convergent validity analyses. The current study also provides psychometric information that can help users choose an appropriate SSPC cutoff score.

“…In addition to the SSPI, the phallometric method emerges as a controlled laboratory-based approach, measuring changes in penile blood volume in response to specific sexual stimuli (Cantor & McPhail, 2015;McPhail et al, 2017). For forensic assessments, the Screening Scale of Pedophilic Crime Scene Behavior (Lehmann, 2022) plays a crucial role in evaluating the behavioral aspects of sex offenders within crime scenes. Meanwhile, the Static-99R, developed by Hanson and Morton-Bourgon (2009), stands as a widely researched actuarial risk assessment tool, for predicting sexual recidivism in adult male sex offenders.…”

The Predictive Validity of the Revised Screening Scale for Pedophilic Interests (SSPI-2)

“…For example, men who scored a five on the SSPI were over five times more likely than those who scored a zero to exhibit greater penile responses to children than to adults ( Seto & Lalumière, 2001 ). Additional research has also suggested that the SSPI has adequate convergent validity with other measures of sexual interest in children (e.g., Banse et al, 2010 ; Dombert et al, 2017 ; Helmus et al, 2015 ; Lehmann et al, 2022 ; McPhail et al, 2020 ; Mokros et al, 2010 ).…”
