Indirect measures of sexual interest in child sex offenders: A Multimethod Approach
Criminal Justice and Behavior, 2010
Although there is strong meta-analytical evidence that deviant sexual interest in children is a major risk factor for recidivism in child sex offenders, the assessment of deviant sexual interest with self-report or phallometric measures is problematic. As an alternative approach for assessment, the Explicit and Implicit Sexual Interest Profile (EISIP) is introduced. It features direct self-report and indirect latency-based measures (Implicit Association Tests [IATs] and viewing time measures) of sexual interest in adults and children. The reliability and validity of the EISIP was investigated using a selected sample of child sex offenders (n = 38) and offender (n = 37) and nonoffender (n = 38) controls. Among the indirect measures, viewing time measures showed higher reliability and convergent and criterion validity than the IATs. However, the IATs independently accounted for criterion variance in multivariate analyses. The combined indirect measures showed good discriminative validity between child sex offenders and controls.

Sexual Abuse: A Journal of Research and Treatment, 26, 107-128.
To aid risk assessment, management, and treatment planning it is essential to assess child sexual abusers’ deviant sexual interests (DSI) and preferences (DSP) for sex with children. However, measurement of DSI/DSP is fraught with psychometric problems. In consequence, research interest has shifted to latency-based indirect measures as a measurement approach to complement self-report and physiological assessment. Utilizing the Explicit and Implicit Sexual Interest Profile (EISIP) – a multimethod approach consisting of self-report, viewing time, and Implicit Association Test (IAT) DSI/DSP measures – we replicated phallometric DSI/DSP differences between child sexual abuser subgroups in a sample of intrafamilial, extrafamilial, and child pornography offenders. DSI/DSP was associated with recidivism risk, offense-behavioral measures of pedophilic interest, and sexual fantasizing. It also negatively correlated with antisociality. Distinguishing between child sexual abuser subtypes and being related to recidivism risk, the EISIP is a useful tool for sexual offender assessments.

The Screening Scale for Pedophilic Interests (SSPI;, a brief measure of sexual attraction to prepubescent children that is based on victim characteristics, was used in two samples of 113 and 145 adult male sex offenders with child victims. In both samples, the SSPI was significantly and positively correlated with an index of phallometrically-measured sexual arousal to stimuli depicting prepubescent children. It was also significantly and positively correlated in both samples with violent recidivism (meaning either nonsexually violent offenses or sexual offenses involving physical contact with a victim), and positively correlated with sexual recidivism, significantly so in the second, larger sample. Focusing on the larger sample, the SSPI added to the predictive accuracy of a measure of general antisociality (the Psychopathy Checklist-Revised), while the phallometric index of sexual arousal did not add predictive accuracy once the other two measures were entered. The SSPI also yielded the same interaction between anomalous sexual interests and psychopathy we had previously reported using phallometric data . These findings suggest that the SSPI has predictive utility among adult male sex offenders with child victims, and accounts for variance in sexual offending that is not explained by phallometric testing.

The development of implicit tests for measuring biases and behavioral predispositions is a recent development within psychology. While such tests are usually researched within a social-cognitive paradigm, behavioral researchers have also begun to view these tests as potential tests of conditioning histories, including in the sexual domain. The objective of this paper is to illustrate the utility of a behavioral approach to implicit testing and means by which implicit tests can be built to the standards of behavioral psychologists. Research findings illustrating the short history of implicit testing within the experimental analysis of behavior are reviewed. Relevant parallel and overlapping research findings from the field of social cognition and on the Implicit Association Test are also outlined. New preliminary data obtained with both normal and sex offender populations are described in order to illustrate how behavior-analytically conceived implicit tests may have potential as inv...
The Screening Scale for Pedophilic Interests (SSPI): Construct, Predictive, and Incremental Validity
This study of 410 adult male sex offenders against children using data from the Dynamic Supervision Project (Hanson, Harris, Scott, & Helmus, 2007) examined the construct, predictive, and incremental validity of the Screening Scale for Pedophilic Interests (SSPI), a brief proxy measure of phallometrically-assessed sexual response to children that is based on sexual victim characteristics (Seto & Lalumière, 2001). As predicted, the SSPI was significantly related to the deviant sexual interests item on the STABLE-2007, a dynamic risk measure encompassing multiple domains, and with the deviant sexual interests item from its predecessor, the STABLE-2000. The SSPI was unrelated (or more weakly related) to items measuring general antisociality. In addition, the SSPI significantly predicted sexual recidivism, defined as new charges or convictions for sexual offenses, and a broader sexual recidivism outcome that included breaches of community supervision conditions that might involve sexually motivated behavior (e.g., being in the presence of children unsupervised). The SSPI did not add to the predictive accuracy of two actuarial risk measures, the Static-99R and Static-200R, but it did add to the predictive accuracy of the STABLE-2007. Additional analyses suggest the SSPI can serve as a substitute for the STABLE-2007 deviant sexual interests item, if necessary (e.g., in archival research), when assessing sexual offenders against children.

The present study examined selected demographic and offense history variables and deviant sexual arousal as predictors of reoffense in a group of 35 untreated child molesters. The measure of deviant sexual arousal was based on laboratory measures of sexual preference using penile plethysmography. Factor analysis of the predictor variables yielded three factors. The measure of deviant arousal, the amount of force used in the offense, whether or not the offender had intercourse with the child victim, and the number of previous victims loaded on the first factor, called Sexual Deviance. IQ and socioeconomic status loaded on the second factor, called Social Status. Age of the offender and age of the victim loaded on the third factor, called Offender Age. Entering the sets of three factor scores as predictors in a multiple correlation, over 20% of the variance in recidivism was explained, but the factor Sexual Deviance was the only significant predictor of recidivism (p < .02). Almost 30% of the variance in number of reoffenses was explained, and both Sexual Deviance ( p < .OI) and Social Status ( p < .lo) were signifcant predic-'Financial support for the work described here was gratefully received from the Center for the
A META-ANALYSIS OF VIEWING TIME MEASURES OF SEXUAL INTEREST IN CHILDREN
Due to unobtrusiveness and ease of implementation, viewing time (VT) measures of sexual interest in children have sparked increasing research interest in forensic contexts over the last two decades. The current study presents two meta-analyses of VT measures adapted to assess pedophilic interest to determine their discrimination between sexual offenders against children (SOC) and non-SOC groups as well as convergent validity (associations with other measures of sexual interest in children). On average, VT measures showed moderate discrimination between criterion groups (fixed-effect d = 0.60, 95% CI [0.51, 0.68], N = 2,705, k = 14) and significant convergent validity with self-reports, penile plethysmography, Implicit Association Tests and offence behavioral measures ranging from r =.18 to r = .38. VT measures, however, provided better discrimination for adults (fixed-effect d = 0.78, 95% CI [0.64, 0.92]) than adolescent samples (fixed-effect d = 0.50, 95% CI [0.40, 0.61]), Qbetween = 9.37, p = .002. Moreover, using pedophilic difference scores within adult samples substantially increased VT measures' validity (fixed-effect d = 1.03, 95% CI [0.82, 1.25], N = 414, k = 7). Results are discussed in terms of their theoretical and applied implications for forensic contexts.

Indirect Behavioral Measures of Cognition among Sexual Offenders
Journal of Sex Research, 2011
Indirect measures of cognition have become an important tool in research on sexual offending. Such methods allow the exploration and testing of models of cognitive processes that might underpin sexual preferences and, in turn, sexual offending. The article reviews studies that have used a large range of indirect techniques (e.g., Implicit Association Test, Implicit Relational Assessment Procedure, Choice Reaction Times, Stroop Interference, Rapid Serial Visual Presentation, Lexical Decision Priming Task, and Viewing Times), and aims to discuss the strengths and weaknesses of this research.
Viewing time as a measure of sexual interest among child molesters and normal heterosexual men
Behaviour Research and Therapy, 1996
Sununary-Although phallometric assessment is the best scientific method for measuring male sexual interest, it is intrusive and highly technical. We examined viewing time as an unobtrusive and technically simple measure of sexual preference and compared the discrimination obtained by viewing time measures with that obtained by phallometric measures. Slides of nude males and females of various ages were shown to child molesters and normal men while their viewing times were recorded. Subjects then rated the sexual attractiveness of the stimulus persons. Phallometric assessments using the same stimulus categories were also given to some of the Ss. Deviance scores calculated from the viewing time data significantly discriminated between the child molesters and the normals, although the discrimination achieved was less than that obtained using phallometric measures. Sexual attractiveness ratings did not differentiate the two groups. Among the normal men, viewing time and sexual attractiveness ratings were highly correlated; but the correlation was much lower for child molesters. Viewing time shows considerable promise as an unobtrusive measure of male sexual interest.
