Progress monitoring is integral to evidence-based practice. Correctional settings, especially the supervision of individuals who commit sexual offenses, elicit public concern; negative outcomes can be catastrophic. Using a prospective longitudinal study of 2,939 men with a history of sexual offenses undergoing community supervision, we examined different models of progress monitoring and how they should inform the assessment of risk for sexual recidivism. We found that the most recent assessment scores of the ACUTE-2007 and STABLE-2007 sexual recidivism risk tools provided the best information about reoffending risk compared to using (a) the worst period of adjustments (i.e., highest risk score), (b) the best period of adjustments (i.e., lowest risk score), or (c) a rolling average of scores. We also found that the latest STABLE-2007 scores incrementally predicted sexual recidivism beyond baseline risk as assessed by demographic and criminal history variables (Static-99R). We conclude that the risk for sexual recidivism changes over time and that community corrections is advanced by repeated assessment of dynamic (changeable) risk factors.

Missing data are pervasive in risk assessment but their impact on predictive accuracy has largely been unexplored. Common techniques for handling missing risk data include summing available items or proration; however, multiple imputation is a more defensible approach that has not been methodically tested against these simpler techniques. We compared the validity of these three missing data techniques across six conditions using STABLE-2007 ( N = 4,286) and SARA-V2 ( N = 455) assessments from men on community supervision in Canada. Condition 1 was the observed data (low missingness), and Conditions 2 to 6 were generated missing data conditions, whereby 1% to 50% of items per case were randomly deleted in 10% increments. Relative predictive accuracy was unaffected by missing data, and simpler techniques performed just as well as multiple imputation, but summed totals underestimated absolute risk. The current study therefore provides empirical justification for using proration when data are missing within a sample., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: L.M.H. is a co-author and certified trainer of the STABLE-2007.

Emotional congruence with children (ECWC) is a psychologically meaningful risk factor for sexual offending against children (SOC). Based on previous research and theory, three models have been proposed to explain ECWC: Blockage, Sexual Domain, and Psychological Immaturity. Using structural equation modelling in a routine correctional sample of men adjudicated for sexual offences ( n = 983), we found little support for all three of these models. Instead, we found that atypical sexual interests, alone, best explained ECWC, with a moderate relationship to ECWC. Using the predictors associated with each of the three models of ECWC, we identified three classes of men with a history of SOC who are high in ECWC using latent class analyses ( n = 377). These three classes generally did not replicate the three models of ECWC. We instead propose three subgroups of men with histories of SOC who are high in ECWC, characterized respectively by: relationship deficits; youth and loneliness; and high sexual and general criminality. High levels of ECWC are predictive of a higher risk of sexual recidivism, regardless of class association; however, these subgroups are differentially at risk for some types of recidivism. Our findings suggest that ECWC is a multi-faceted construct, which is still not well understood., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Risk tools containing dynamic (potentially changeable) factors are routinely used to evaluate the recidivism risk of justice-involved individuals. Although frequent reassessments are recommended, there is little research on how the predictive accuracy of dynamic risk assessments changes over time. This study examined the extent to which predictive accuracy decreases over time for the ACUTE-2007 and the STABLE-2007 sexual recidivism risk tools. We used two independent samples of men on community supervision ( N Study 1 = 795; N Study 2 = 4,221). For all outcomes (sexual, violent, and any recidivism [including technical violations]), reassessments improved predictive accuracy, with the largest effects found for the most recent assessment (i.e., those closest in time prior to the recidivism event). Based on these results, we recommend that ACUTE-2007 assessments occur at least every 30 days and that the STABLE-2007 assessments occur every 6 months or after significant life changes (e.g., successful completion of treatment)., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: R.

With the advancement of technology, sexting has become more prominent in high school and university samples. The current study examined the rates and characteristics of sexting among an online sample of 2,828 young adults aged 18-30, primarily from the U.S. and Canada. We found that most participants sext (81%), sext often (most report ≥ 11 sexts), and start young (most by 16-17 years of age). Common reasons for sexting echoed reasons for participating in other normative sexual behaviors, including that it was sexually arousing, they were asked and wanted to reciprocate, or they wanted to flirt. Sexual coercion was a gendered phenomenon, with 1 in 10 cisgender women and 1 in 50 cisgender men reporting having sent a sext due to being threatened. The body parts captured in cisgender men's sexts were more diverse, whereas cisgender women focused on their chest, underwear/genitalia, and stomach. Sexual orientation was also found to be a relevant factor, with different patterns in sexting experiences emerging across identities. The current study adds to the mounting evidence that sexting is a normative sexual behavior. Sexual education programs should provide youth with information on consent and safe sexting practices rather than follow an abstinence approach., (© 2023.

Objective: Risk assessment is essential to effective correctional practice. For individuals with contact sexual offenses, many risk tools are available. There are fewer options, however, for individuals whose sexual offending exclusively involves child sexual exploitation materials (CSEM; legally referred to in Canada and the United States as child pornography)., Hypotheses: The present study examined the predictive validity of the ACUTE-2007 and STABLE-2007 sexual recidivism risk tools among men with CSEM offenses. We expected these tools to show moderate predictive validity across study groups., Method: We compared the scales' discrimination and calibration across three groups: (a) 1,042 men with contact sexual offenses against children (baseline comparison), (b) 228 men with exclusive CSEM offending (no contact sexual offenses), and (c) 80 men with both contact sexual offenses and CSEM offenses., Results: We found that the ACUTE-2007 and STABLE-2007 total scores and items had comparable (and often better) discrimination for men with CSEM offending compared with contact sexual offending against children in the prediction of any sexual recidivism, violent recidivism, and any recidivism. Calibration analyses indicated that the overall sexual recidivism rates for the median ACUTE-2007 and STABLE-2007 scores were similar for men with exclusive CSEM offenses compared with men with any contact offending against children. Almost all of the sexual recidivism for the CSEM-exclusive group involved further CSEM offenses., Conclusions: This study supports the use of these tools to rank-order men with CSEM offending in terms of their risk of reoffending and to help direct treatment and management efforts.

Multidimensional item response theory (MIRT) was used to study the construct validity of the Static-2002R, an actuarial scale for the assessment of reoffending among adult men who sexually offended. Using a sample of 2,569 individuals with a history of sexual crime, exploratory factor analysis (EFA) extracted three factors: Persistence/Paraphilia, General Criminality, and Youthful Stranger Aggression. MIRT confirmed the factor structure identified in the EFA model and provided item-level data on discrimination and difficulty. All Static-2002R items showed moderate to very high discrimination and covered a wide range of risk levels (i.e., difficulty). MIRT analyses attested to the construct validity of the scale, as no items were identified as problematic and the resulting factor structure was consistent with that of earlier studies. Considering the stability of results pertaining to the factor structure of the Static-2002R and the advantages of dimensional scoring, we recommend the integration of dimensional scores in the scale.

A Five-Level Risk and Needs system has been proposed as a common language for standardizing the meaning of risk levels across risk/need tools used in corrections. Study 1 examined whether the Five-Levels could be applied to BARR-2002R ( N = 2,390), an actuarial tool for general recidivism. Study 2 examined the construct validity of BARR-2002R risk levels in two samples of individuals with a history of sexual offending ( N = 1,081). Study 1 found reasonable correspondence between BARR-2002R scores and four of the five standardized risk levels (no Level V). Study 2 found that the profiles of individuals in Levels II, III, and IV were mostly consistent with expectations; however, individuals in the lowest risk level (Level I) had more criminogenic needs than expected based on the original descriptions of the Five-Levels. The Five-Level system was mostly successful when applied to BARR-2002R. Revisions to this system, or the inclusion of putatively dynamic risk factors and protective factors, may be required to improve alignment with the information provided by certain risk tools.

In an online survey of 274 self-identified child-attracted persons (CAPs), we examined the attraction ratings given to sets of 9 physical and 12 psychological features of children, and asked CAPs to identify additional features that were not listed. We also examined the relationships between these attraction ratings and attraction to children dimensions (age mono-/polymorphism, exclusivity of attraction to children, and gender attraction), history of falling in love with a child, and detected sexual offending history. There was relatively little differentiation across physical features and psychological features; all averages were approximately 4 or higher on a 5-point scale. Attraction ratings were mostly weakly and inconsistently related to our other study variables. The exception was that CAPs who had fallen in love with a child rated 11 out of 12 psychological features as more attractive than CAPs who had not fallen in love with a child, with small to moderate effect sizes. These two groups did not differ in ratings for physical features. Our qualitative content analysis of participant-suggested features revealed six physical themes (inter alia, face and head, children's bodies) and five psychological themes (inter alia, personality, harmlessness) that were important to CAPs' attraction to children.

Objective measures of sexual interest are important for research on human sexuality. There has been a resurgence in research examining pupil dilation as a potential index of sexual orientation. We carried out a meta-analytic review of studies published between 1965 and 2020 (Mdn year = 2016) measuring pupil responses to visual stimuli of adult men and women to assess sexual interest. Separate meta-analyses were performed for six sexual orientation categories. In the final analysis, 15 studies were included for heterosexual men (N = 550), 5 studies for gay men (N = 65), 4 studies for bisexual men (N = 124), 13 studies for heterosexual women (N = 403), and 3 studies for lesbian women (N = 132). Only heterosexual and gay men demonstrated discrimination in pupillary responses that was clearly in line with their sexual orientation, with greater pupil dilation to female and male stimuli, respectively. Bisexual men showed greater pupil dilation to male stimuli. Although heterosexual women exhibited larger pupils to male stimuli compared to female stimuli, the magnitude of the effect was small and non-significant. Finally, lesbian women displayed greater pupil dilation to male stimuli. Three methodological moderators were identified-the sexual explicitness of stimulus materials, the measurement technique of pupillary response, and inclusion of self-report measures of sexual interest. These meta-analyses are based on a limited number of studies and are therefore preliminary. However, the results suggest that pupillary measurement of sexual interest is promising for men and that standardization is essential to gain a better understanding of the validity of this measurement technique for sexual interest., (© 2021.

STABLE-2007 is a measure of risk-relevant propensities for adult males convicted of a sexual offense. This meta-analysis evaluated the ability of STABLE-2007 and its items to discriminate between recidivists and nonrecidivists, and the extent to which STABLE-2007 improves prediction over and above Static-99R. Based on 21 studies (12 unique samples, N = 6,955), we found that STABLE-2007 was significantly and incrementally related to sexual recidivism, violent (nonsexual) recidivism, violent (including sexual) recidivism, and any crime. Scores on STABLE-2007 items and the three STABLE-2000 attitude items also discriminated between individuals who sexually reoffended and those who did not sexually reoffend. These findings support the use of STABLE-2007 in applied risk assessment practice and the interpretation of STABLE-2007 items as indicators of treatment and supervision targets.

This meta-analysis examined whether theoretically and clinically relevant differences exist between male adolescents who have sexually offended against intrafamilial victims (AIV) and male adolescents who have sexually offended against extrafamilial victims (AEV). A total of 26 independent samples (8 published and 18 unpublished) that compared a total of 2169 AIV and 2852 AEV were analyzed. The results of this meta-analysis indicate that categorizing male adolescents who commit sexual offenses based on their relationship to victims is a meaningful distinction. We found that AIV presented with greater atypical sexual interests, increased sexual regulation issues, more severe family dysfunction, more extensive childhood maltreatment histories, and greater internalizing psychopathology than AEV. Conversely, AEV presented with more indicators of antisociality than AIV, suggesting that extrafamilial sexual offending might fit better with a generalist explanation of adolescent sexual offending. Findings highlight the value of assessing family dysfunction and maltreatment history, sexual development and regulation, and general delinquency factors to better understand adolescents who have committed a sexual offense.

Objectives: Few studies have examined how much individuals change on intermediate targets of risk to reoffend. Even fewer studies have examined the extent to which change on such measures predict reoffending. Establishing the validity of intermediate measures requires a multistep approach that (a) assesses the reliability of the change, (b) assesses change using statistical analyses that can account for measurement error, and (c) examines the extent to which change on these intermediate measures predict reoffending., Method: The current study examined the validity of an intermediate measure of risk to reoffend scored by community supervision officers (i.e., ACUTE-2007) in a large sample of men convicted of sexually motivated offenses ( N = 632)., Results: We found that risk to reoffend changes across time, the pattern of change varies across individuals, risk levels can predict different patterns of change, and that the best predictors of recidivism are the latest score or a rolling average of scores., Conclusions: Community supervision can use recent information concerning the community adjustment of their clients to predict recidivism. Best practice includes updating assessments and adjusting supervision practices based on their clients' most recent assessment, or the average of previous assessments.

Few studies of pedophilia or hebephilia have included questions about romantic attraction. We conducted an anonymous online survey of 306 men who self-reported as sexually attracted to children. The majority (72%) of participants reported they had fallen in love with a child in their lifetime. Participants reported greater feelings of attachment to children than feelings of infatuation. Though sexual attraction and falling in love were strongly correlated, they were not synonymous. Participants who reported pedohebephilia (defined in this study as attraction to prepubescent and pubescent children) were more likely to have fallen in love with a child than participants who reported pedohebe-ephebophilia (defined as attraction to prepubescent, pubescent, and post-pubescent minors). Also, participants with an exclusive attraction to children were more likely to have fallen in love with a child than participants who were equally attracted to children and adults. The results of this study were consistent with the suggestion of Seto (2012) that pedohebephilia could be considered a form of sexual orientation for age, which includes both sexual and romantic attraction.

Although prior research suggests associations between parental characteristics and later sexual offending in offspring, possible links between early pregnancy-related factors and sexual offending remain unclear. Early risk markers unique to sexual offending, however, may be more prominent among sexual offenders with atypical sexual interests, such as individuals involved with child sexual exploitation material (CSEM; also referred to as child pornography). We examined the prospective association between parental and pregnancy-related risk markers and a behavioral indicator of pedophilic interest, CSEM offending. All 655 men born in Sweden and convicted of CSEM offending between 1988 to 2009 were matched 1:5 on sex, birth year, and county of birth in Sweden to 3,928 controls without sexual or nonsexual violent convictions. Paternal age (adjusted odds ratio [AOR] = 1.3, 95% confidence interval [CI] [1.1, 1.7]), parental education (AOR = 0.8, 95% CI [0.6, 0.9]), parental violent criminality (AOR = 2.9, 95% CI [2.2, 3.8]), number of older brothers (AOR = 0.8, 95% CI [0.6, 0.9] per brother), and congenital malformations (AOR = 1.7, 95% CI [1.2, 2.4]) all independently predicted CSEM convictions. This large-scale, nationwide study suggests parental risk markers for CSEM offending. We did not, however, find convincing evidence for pregnancy-related risk markers, with the exception of congenital malformations and having fewer older brothers.

Viewing time tasks using still pictures to assess age and gender sexual interests have been well validated and are commonly used. The use of film clips in a viewing time task would open up interesting possibilities for the study of sexual interest toward sexual targets or activities that are not easily captured in still pictures. We examined the validity of a viewing time task using film clips to assess sexual interest toward male and female targets, in a sample of 52 young adults. Film clips produced longer viewing times than still pictures. For both men and women, the indices derived from the film viewing time task were able to distinguish individuals who identified as homosexual (14 men, 8 women) from those who identified as heterosexual (15 men, 15 women), and provided comparable group differentiation as indices derived from a viewing time task using still pictures. Men's viewing times were more gender-specific than those of women. Viewing times to film clips were correlated with participants' ratings of sexual appeal of the same clips, and with viewing times to pictures. The results support the feasibility of a viewing time measure of sexual interest that utilizes film clips and, thus, expand the types of sexual interests that could be investigated (e.g., sadism, biastophilia).

This article describes principles for developing risk category labels for criterion referenced prediction measures, and demonstrates their utility by creating new risk categories for the Static-99R and Static-2002R sexual offender risk assessment tools. Currently, risk assessments in corrections and forensic mental health are typically summarized in 1 of 3 words: low, moderate, or high. Although these risk labels have strong influence on decision makers, they are interpreted differently across settings, even among trained professionals. The current article provides a framework for standardizing risk communication by matching (a) the information contained in risk tools to (b) a broadly applicable classification of "riskiness" that is independent of any particular offender risk scale. We found that the new, common STATIC risk categories not only increase concordance of risk classification (from 51% to 72%)-they also allow evaluators to make the same inferences for offenders in the same category regardless of which instrument was used to assign category membership. More generally, we argue that the risk categories should be linked to the decisions at hand, and that risk communication can be improved by grounding these risk categories in evidence-based definitions.

The current study examined the extent to which 1136 men were able to inhibit their sexual arousal on a phallometric assessment, when instructed to do so. Although the observed changes between the two conditions (i.e., Normal and Suppression) were small to moderate in magnitude, the change was not more than what would be expected by measurement error for most participants (e.g., 83% of pedophilic sex offenders against children did not successfully inhibit their sexual arousal in the Suppression condition). There were very few variables that were associated with the ability to suppress. Higher Pedophilia Index scores in the Suppression condition predicted a greater likelihood of sexual recidivism among sex offenders (hazard ratio = 1.17, 95% CI [1.04, 1.32]), but the ability to suppress sexual arousal was not found to predict sexual recidivism. The current study highlights the importance of accounting for measurement error and found that, when doing so, most sex offenders against children are unable to successfully inhibit their sexual arousal to children when instructed to do so, and that the ability to suppress sexual arousal is not associated with recidivism.

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 = 2705, 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]), Q between  = 9.37, p = .002. Moreover, compared to absolute scores, 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.

Background: Prior studies suggest parental and perinatal risk factors are associated with later offending. It remains uncertain, however, if such risk factors are similarly related to sexual offending., Method: We linked socio-demographic, family relations, and perinatal (obtained at birth) data from the nationwide Swedish registers from 1973 to 2009 with information on criminal convictions of cases and control subjects. Male sex offenders (n = 13 773) were matched 1:5 on birth year and county of birth in Sweden to male controls without sexual or non-sexual violent convictions. To examine risk-factor specificity for sexual offending, we also compared male violent, non-sexual offenders (n = 135 953) to controls without sexual or non-sexual violent convictions. Predictors included parental (young maternal or paternal age at son's birth, educational attainment, violent crime, psychiatric disorder, substance misuse, suicide attempt) and perinatal (number of older brothers, low Apgar score, low birth weight, being small for gestational age, congenital malformations, small head size) variables., Results: Conditional logistic regression models found consistent patterns of statistically significant, small to moderate independent associations of parental risk factors with sons' sexual offending and non-sexual violent offending. For perinatal risk factors, patterns varied more; small for gestational age and small head size exhibited similar risk effects for both offence types whereas a higher number of older biological brothers and any congenital malformation were small, independent risk factors only for non-sexual violence., Conclusions: This nationwide study suggests substantial commonalities in parental and perinatal risk factors for the onset of sexual and non-sexual violent offending., Competing Interests: Declaration of Interest None.

Correlations are the simplest and most commonly understood effect size statistic in psychology. The purpose of the current paper was to use a large sample of real-world data (109 correlations with 60,415 participants) to illustrate the base rate dependence of correlations when applied to dichotomous or ordinal data. Specifically, we examined the influence of the base rate on different effect size metrics. Correlations decreased when the dichotomous variable did not have a 50 % base rate. The higher the deviation from a 50 % base rate, the smaller the observed Pearson's point-biserial and Kendall's tau correlation coefficients. In contrast, the relationship between base rate deviations and the more commonly proposed alternatives (i.e., polychoric correlation coefficients, AUCs, Pearson/Thorndike adjusted correlations, and Cohen's d) were less remarkable, with AUCs being most robust to attenuation due to base rates. In other words, the base rate makes a marked difference in the magnitude of the correlation. As such, when using dichotomous data, the correlation may be more sensitive to base rates than is optimal for the researcher's goals. Given the magnitude of the association between the base rate and point-biserial correlations (r = -.81) and Kendall's tau (r = -.80), we recommend that AUCs, Pearson/Thorndike adjusted correlations, Cohen's d, or polychoric correlations should be considered as alternate effect size statistics in many contexts.

Given that sexual offenders are more likely to reoffend with a nonsexual offense than a sexual offense, it is useful to have risk scales that predict general recidivism among sexual offenders. In the current study, we examined the extent to which two commonly used risk scales for sexual offenders (Static-99R and Static-2002R) predict violent and general recidivism, and whether it would be possible to improve predictive accuracy for these outcomes by revising their items. Based on an aggregated sample of 3,536 adult male sex offenders from Canada, the United States, and Europe (average age of 39 years), we found that a scale created from the Age at Release item and the General Criminality subscale of Static-2002R predicted nonsexual violent, any violent, and general recidivism significantly better than Static-99R or Static-2002R total scores. The convergent validity of this new scale (Brief Assessment of Recidivism Risk-2002R [BARR-2002R]) was examined in a new, independent data set of Canadian high-risk adult male sex offenders (N = 360) where it was found to be highly correlated with other risk assessment tools for general recidivism and the Psychopathy Checklist-Revised (PCL-R), as well as demonstrated similar discrimination and calibration as in the development sample. Instead of using total scores from the Static-99R or Static-2002R, we recommend that evaluators use the BARR-2002R for predicting violent and general recidivism among sex offenders, and for screening for the psychological dimension of antisocial orientation., (© The Author(s) 2015.)

Empirical actuarial risk tools are routinely used to assess the recidivism risk of adult sexual offenders. Compared with other forms of risk assessment, one advantage of actuarial risk tools is that they provide recidivism rate estimates. Previous research, however, suggests that there is considerable variability in the recidivism rates associated with the most commonly used sexual offender risk assessment tools (Static-99/R, Static-2002/R). The current study examined the extent to which the variability in the recidivism rates across 21 Static-99R studies (N = 8,805) corresponded to the normative groups proposed by the STATIC development group (routine, treatment, high risk/high need). We found strong evidence that routine (i.e., complete) samples were, on average, less likely to reoffend with a sexual offense than offenders in the high-risk/high-need samples (i.e., those explicitly preselected on risk-relevant variables external to STATIC scales). The differences between routine/complete and high-risk/high-need samples, however, were only consistently observed for offenders with low or moderate scores; for offenders with high STATIC scores, the 5-year sexual recidivism rates for these two groups were not meaningfully different. There was only limited evidence to support treatment samples as a distinct sample type; consequently, the use of separate normative tables for treatment samples is not recommended. The current results reinforce the value of regularly updating the norms for empirical actuarial risk tools. Options are discussed on how STATIC scores could be used to inform recidivism rates estimates in applied assessments., (© The Author(s) 2015.)

The most commonly used risk assessment tools for predicting sexual violence focus almost exclusively on static, historical factors (e.g., characteristics of prior offences). Consequently, they are assumed to be unable to directly inform the selection of treatment targets or evaluate change. In this article, we argue that this limitation can be mitigated by using latent variable models as a framework to link historical risk factors to the psychological characteristics of offenders. Accordingly, we conducted a factor analysis of the 13 nonredundant items from the two most commonly used risk tools for sexual offenders (Static-99R and Static-2002R) to identify the psychological information contained in these tools. Three factors were identified: (a) persistence/paraphilia, a construct related to sexual criminality, especially of the pedophilic type; (b) youthful stranger aggression, a construct centered on young age and offence seriousness; and (c) general criminality, a construct that reflected the diversity and magnitude of criminal careers. These constructs predicted sexual recidivism with similar accuracy, but only youthful stranger aggression and general criminality predicted nonsexual recidivism. These results indicate that risk tools for sexual violence are multidimensional, and support a shift from a focus on atheoretical risk markers to the assessment of psychologically meaningful constructs., (© The Author(s) 2015.)

Intrafamilial child sexual abuse is a serious social and health problem, yet explanations of sexual offending against children that emphasize antisocial tendencies and atypical sexual interests do not adequately explain intrafamilial offending. In this meta-analysis, we tested other explanations of intrafamilial child sexual abuse by examining 78 independent samples that compared a total of 6605 intrafamilial offenders to a total of 10,573 extrafamilial offenders, in studies disseminated between 1978 and 2013 (Mdn=2000). Intrafamilial offenders were significantly lower on variables reflecting antisocial tendencies (e.g., criminal history, juvenile delinquency, impulsivity, substance use, and psychopathy) and atypical sexual interests (e.g., pedophilia, other paraphilias, and excessive sexual preoccupation). Contrary to other explanations that have been proposed, intrafamilial offenders scored lower on offense-supportive attitudes and beliefs, emotional congruence with children, and interpersonal deficits; intrafamilial offenders also did not differ from extrafamilial offenders on most indicators of psychopathology. Intrafamilial offenders were, however, more likely to have experienced sexual abuse, family abuse or neglect, and poor parent-child attachments. There were too few studies to examine family dynamics - spousal relationship quality, parent-child victim relationship, and family functioning more generally - even though these factors have been frequently mentioned in the clinical and theoretical literatures. Implications for theories of intrafamilial sexual offending, treatment, and future directions for research are discussed., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Background: Sexual crime is an important public health concern. The possible causes of sexual aggression, however, remain uncertain., Methods: We examined familial aggregation and the contribution of genetic and environmental factors to sexual crime by linking longitudinal, nationwide Swedish crime and multigenerational family registers. We included all men convicted of any sexual offence (N = 21,566), specifically rape of an adult (N = 6131) and child molestation (N = 4465), from 1973 to 2009. Sexual crime rates among fathers and brothers of sexual offenders were compared with corresponding rates in fathers and brothers of age-matched population control men without sexual crime convictions. We also modelled the relative influence of genetic and environmental factors to the liability of sexual offending., Results: We found strong familial aggregation of sexual crime [odds ratio (OR) = 5.1, 95% confidence interval (CI) = 4.5-5.9] among full brothers of convicted sexual offenders. Familial aggregation was lower in father-son dyads (OR = 3.7, 95% CI = 3.2-4.4) among paternal half-brothers (OR = 2.1, 95% CI = 1.5-2.9) and maternal half-brothers (OR = 1.7, 95% CI = 1.2-2.4). Statistical modelling of the strength and patterns of familial aggregation suggested that genetic factors (40%) and non-shared environmental factors (58%) explained the liability to offend sexually more than shared environmental influences (2%). Further, genetic effects tended to be weaker for rape of an adult (19%) than for child molestation (46%)., Conclusions: We report strong evidence of familial clustering of sexual offending, primarily accounted for by genes rather than shared environmental influences. Future research should possibly test the effectiveness of selective prevention efforts for male first-degree relatives of sexually aggressive individuals, and consider familial risk in sexual violence risk assessment.

The current meta-analysis compared the characteristics of online child pornography-only offenders, typical (offline) sex offenders against children, and offenders with both child pornography and contact sex offences against children (mixed). Based on 30 unique samples (comparison ns ranging from 98 to 2,702), the meta-analysis found key differences between groups. Offenders who committed contact sex offences were more likely to have access to children than those with only child pornography offences. In contrast, offenders who used the internet to commit sexual offences had greater access to the internet than those with contact sex offenders. Differences between the groups, however, were not limited to differential opportunities. Sex offenders against children and mixed offenders were found to score higher on indicators of antisociality than online child pornography offenders (CPOs). CPOs were also more likely to have psychological barriers to sexual offending than sex offenders against children and mixed offenders (e.g., greater victim empathy). Mixed offenders were found to be the most pedophilic, even more than CPOs. The findings suggest that offenders who restricted their offending behavior to online child pornography offences were different from mixed offenders and offline sex offenders against children, and that mixed offenders were a particularly high risk group.

Research and theoretical models have consistently identified sexual interest in children as a key factor involved in child sexual offending. However, there is only moderate agreement in the diagnosis of pedophilia and different assessment methods identify different offenders as pedophiles. The current study examined the discriminative and convergent validity of three different measures of sexual interest in children. Participants included sex offenders and nonsex offenders recruited from federal prisons (i.e., offenders serving sentences of more than 2 years) in Ontario, Canada. Child molesters' responses (n = 35) were not significantly different from nonsex offenders (n = 21) on an implicit measure of sexual interest in children (Sexual Attraction to Children Implicit Association Test [SAC-IAT] d = 0.44, 95% CI [-0.11, 0.99]), but differed on the self-report (Sexual Interest Profiling System; d = 0.83, 95% CI [0.27, 1.39]) and viewing time (d = 1.15, 95% CI [0.54, 1.75]) measures. Findings did not provide clear support for the superiority of a multimodal approach, possibly due to the relatively small sample. More often than not, convergence between the three measures was observed (n = 74). Findings from the present study are an important step toward understanding the relationship between different measures of sexual interest in children and establishing their validity., (© The Author(s) 2013.)

Given the widespread use of empirical actuarial risk tools in corrections and forensic mental health, it is important that evaluators and decision makers understand how scores relate to recidivism risk. In the current study, we found strong evidence for a relative risk interpretation of Static-99R scores using 8 samples from Canada, United Kingdom, and Western Europe (N = 4,037 sex offenders). Each increase in Static-99R score was associated with a stable and consistent increase in relative risk (as measured by an odds ratio or hazard ratio of approximately 1.4). Hazard ratios from Cox regression were used to calculate risk ratios that can be reported for Static-99R. We recommend that evaluators consider risk ratios as a useful, nonarbitrary metric for quantifying and communicating risk information. To avoid misinterpretation, however, risk ratios should be presented with recidivism base rates.

This study tested 3 decision rules for combining actuarial risk instruments for sex offenders into an overall evaluation of risk. Based on a 9-year follow-up of 940 adult male sex offenders, we found that Rapid Risk Assessment for Sex Offender Recidivism (RRASOR), Static-99R, and Static-2002R predicted sexual, violent, and general recidivism and provided incremental information for the prediction of all 3 outcomes. Consistent with previous findings, the incremental effect of RRASOR was positive for sexual recidivism but negative for violent and general recidivism. Averaging risk ratios was a promising approach to combining these risk scales, showing good calibration between predicted (E) and observed (O) recidivism rates (E/O index = 0.93, 95% CI [0.79, 1.09]) and good discrimination (area under the curve = 0.73, 95% CI [0.69, 0.77]) for sexual recidivism. As expected, choosing the lowest (least risky) risk tool resulted in underestimated sexual recidivism rates (E/O = 0.67, 95% CI [0.57, 0.79]) and choosing the highest (riskiest) resulted in overestimated risk (E/O = 1.37, 95% CI [1.17, 1.60]). For the prediction of violent and general recidivism, the combination rules provided similar or lower discrimination compared with relying solely on the Static-99R or Static-2002R. The current results support an averaging approach and underscore the importance of understanding the constructs assessed by violence risk measures.

The current study presents a quantitative review of the discriminative and convergent validity of Implicit Association Test (IAT) measures adapted to assess sexual interest in children. IAT measures were able to distinguish sex offenders against children (SOC) from non-SOC (M weighted d from random-effects = 0.63, 95 % CI [0.42-0.83], N = 707, k = 12). The largest group differences were found between SOC and non-offenders, followed by non-sex offenders and rapists. IAT measures using sex versus not sex (and similar attribute categories, such as sex vs. neutral) provided superior discrimination compared to IAT measures using sexy versus not sexy (and similar attribute categories, such as erotic vs. non-erotic). The IAT measures had a moderate relationship to self-report (r = .27, 95 % CI [.13-.40], N = 182), sexual offense history variables (r = .27, 95 % CI [.08-.43], N = 145), and viewing time (r = .30, 95 % CI [.16-.43], N = 180) measures of sexual interest in children. Although these IAT measures can discriminate between groups and show convergence with other measures of sexual interest, a better understanding of the construct validity of these tools is required before their use in the assessment, treatment, and supervision of sex offenders.

Attitudes supportive of sexual offending figure prominently in theories of sexual offending, as well as in contemporary assessment and treatment practices with sex offenders. Based on 46 samples (n = 13,782), this meta-analysis found that attitudes supportive of sexual offending had a small, yet reasonably consistent, relationship with sexual recidivism (Cohen's d = .22). To the extent that differences were observed, attitudes predicted recidivism better for child molesters than for rapists. There was no difference in the predictive accuracy of attitudes assessed at pretreatment or at posttreatment. The current study indicates that attitudes supportive of sexual offending is a psychologically meaningful risk factor for sex offenders. However, given that many different constructs have been designated as sex offender attitudes, further research and theory is needed to understand how these various constructs contribute to recidivism.

Criterion-referenced measures, such as those used in the assessment of crime and violence, prioritize predictive accuracy (discrimination) at the expense of construct validity. In this article, we compared the discrimination and incremental validity of three commonly used criterion-referenced measures for sex offenders (Rapid Risk Assessment for Sex Offence Recidivism [RRASOR], Static-99R, and Static-2002R). In a meta-analysis of 20 samples (n = 7,491), Static-99R and Static-2002R provided similar discrimination but outperformed the RRASOR in the prediction of sexual, violent, and any recidivism. Remarkably, despite large correlations between them (rs ranging from .70 to .92), these risk scales consistently added incremental validity to one another. The direction of the incremental effects, however, was not consistently positive. When controlling for the other measures, high scores on the RRASOR were associated with lower risk for violent and any recidivism. We also examined different methods of combining risk scales and found that the averaging approach produced better discrimination than choosing the highest score and produced better calibration than either choosing the lowest or highest risk score. The findings reinforce the importance of understanding the psychological content of criterion-referenced measures, even when the sole purpose is to predict a particular outcome and provide some direction concerning the best methods for combining risk scales.

The current study compared 38 lower risk (based on actuarial risk assessments) men convicted of contact sexual offenses against children, 38 child pornography offenders, and 70 solicitation offenders (also known as luring or traveler offenders). Solicitation and child pornography offenders were better educated than contact offenders but did not differ on other sociodemographic variables. In comparison to child pornography offenders, solicitation offenders had lower capacity for relationship stability and lower levels of sex drive/preoccupation and deviant sexual preference. Solicitation offenders were also more problematic than lower risk contact offenders on sex drive/preoccupation and capacity for relationship stability and had greater self-reported use of child pornography. Differences between groups on two actuarial risk measures, the Static-99 and the VASOR, were inconsistent. This study suggests that solicitation offenders differ in meaningful ways from lower risk contact offenders and child pornography offenders and, consequently, in risk, treatment, and supervision needs., ((PsycINFO Database Record (c) 2012 APA, all rights reserved).)
