Review of risk assessment instruments for juvenile sex offenders: what is next?

Interrater reliability and experiences of Assessment, Intervention, and Moving-on 3 Assessment Model in a multidisciplinary Norwegian sample

Background

Assessing minors with harmful sexual behavior (HSB) is a complex and sensitive task. The AIM3 Assessment Model was developed to assist practitioners with information collection and HSB evaluations.

Objective

In this study, we explore the interrater reliability and the practitioners' experience with the AIM3.

Participants and setting

The multidisciplinary sample (n = 56) was recruited in Norway. The participants' mean age is 43.2 years (SD 9.5). The sample is 79% female and 21% male. Mean years of experience is 17.6 years (SD 9.5).

Methods

The participants used the Norwegian version of the AIM3 to score three case vignettes. A survey containing questions about competence and experience was filled out. We used the intraclass correlation coefficient (ICC) to estimate interrater reliability as well as descriptive statistics to show experience.

Results

The estimated ICC for overall AIM3 factors is 0.547 (95% CI = 0.471, 0.634); for domain scores, the estimated ICC is 0.697 (95% CI = 0.548, 0.852). Both are in the moderate range. The majority of the participants reported that they will probably use the AIM3 in the future and that their experience with the AIM3 was highly useful with, for example, empirically informed decision-making and for intervention and safety planning.

Conclusion

The moderate ICC results and the sample's generally positive experience with the AIM3 may indicate further usefulness in a Norwegian multidisciplinary setting. We provide recommendations on how the AIM3 and similar HSB assessments can be further evaluated and developed.

Reliability and Predictive Validity of the Juvenile Sex Offender Assessment Protocol-II in an Australian Context

This study investigated the reliability and predictive validity of the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II), in an Australian context, and for Australian Indigenous and non-Indigenous youth. Participants were 123 (n = 91 non-Indigenous; n = 32 Indigenous) youth assessed using the J-SOAP-II and followed up over an average period of 4 years. The reliability of the J-SOAP-II was assessed using measures of internal consistency (Cronbach's alphas and inter-item correlations). Receiver operating characteristic (ROC) analyses were conducted to assess the J-SOAP-II's validity in predicting sexual and non-sexual (violent and non-violent) recidivism. Overall, the J-SOAP-II demonstrated moderate to high levels of reliability and weak to moderate levels of validity for predicting sexual and non-sexual (violent and non-violent) recidivism for the whole sample. While the J-SOAP-II total score was significantly associated with non-sexual (violent and non-violent) recidivism for non-Indigenous youth, it was not significantly associated with any of the outcome variables for Indigenous youth. Across all analyses, the dynamic scales of the J-SOAP-II predicted recidivism with greater accuracy than the static scales. However, the static scales had greater accuracy in predicting the risk of sexual recidivism for Indigenous youth. While a reliable measure, these preliminary findings raise questions about the validity of the J-SOAP-II for predicting sexual recidivism for Indigenous and non-Indigenous youth in an Australian context, and warrant further investigation.

The predictive and incremental validity of ADHD beyond the VRAG-R in a high-risk sample of young offenders

The VRAG-R is a well-established actuarial risk-assessment instrument, which was originally developed for assessing violent recidivism risk in adult male offenders. Whether or not the VRAG-R can also predict violent recidivism in young offenders is unclear so far. In the emergence of juvenile offending, attention-deficit/hyperactivity disorder (ADHD) seems to be of major importance suggesting that it could be relevant for risk assessment as well. Thus, we examined the predictive accuracy of the VRAG-R in a high-risk sample of N = 106 (M = 18.3 years, SD = 1.8) young offenders and assessed the incremental predictive validity of ADHD symptomatology beyond the VRAG-R. Within a mean follow-up time of M = 13 years (SD = 1.2), n = 65 (62.5%) young offenders recidivated with a violent offense. We found large effect sizes for the prediction of violent and general recidivism and re-incarcerations using the VRAG-R sum scores. Current ADHD symptomatology added incremental predictive validity beyond the VRAG-R sum scores concerning the prediction of general recidivism but not of violent recidivism. The results supported the use of the VRAG-R for predicting violent recidivism in young offenders. Because ADHD symptomatology improves the predictive performance of the VRAG-R regarding general recidivism, we argue that addressing ADHD symptoms more intensively in the juvenile justice system is of particular importance concerning a successful long-term risk management in adolescents and young adults.

A Critical Assessment of the Youth Needs and Progress Scale

Evaluated is a recently developed tool, the Youth Needs and Progress Scale (YNPS). Reported is the surprisingly palpable lack of adherence to scientific standards. A demonstrable absence of attention and accordance to scientific methods related to research and developing psychometrics is evident, that is, taking a colander approach when constructing the tool. The rudimentary steps of this project were described by Kang et al. (2019) and subsequently critiqued by this author. Significant concerns previously delineated were not addressed, but rather crystalized in a substantial U.S. federally tax funded grant for a substandard tool. These are described in this article (i.e., lack of adequate literature review, citing selective research findings, referencing face validity tools, problematic research design). The key concern is the reliance on risk recidivism tools (J-SOAP-II and ERASOR), partially based on adult research and empirically shown to have inconsistently performed in risk assessment studies.

Are Juveniles Who Have Committed Sexual Offenses the Same Everywhere? Psychometric Properties of the Juvenile Sex Offender Assessment Protocol-II in a Portuguese Youth Sample

Over the last decade, we have witnessed consistent advances in risk assessment procedures, namely the validation of those used with juveniles who have committed sexual offenses. The adaptation of these instruments into other languages requires research examining the conceptual and metric equivalence of the instruments, not just translation equivalence. Informed by data from 141 boys, aged 13 to 18, the psychometric properties of the Portuguese version of the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II), regarding reliability and construct validation, are presented and discussed. Factor structure, internal consistency, and interrater reliability were examined, and a reliable factorial structure that was consistent with the original validation of the J-SOAP was found. Scales 2 and 3 had good internal consistency, and Scale 1 had acceptable internal consistency. Results regarding concurrent validity revealed mostly statistically significant correlations. The implications of this research for juvenile sex offender risk assessments are discussed.

Cognitive-behavioural therapy (CBT) interventions for young people aged 10 to 18 with harmful sexual behaviour

BACKGROUND

Around 1 in 1000 adolescents aged 12 to 17 years old display problematic or harmful sexual behaviour (HSB). Examples include behaviours occurring more frequently than would be considered developmentally appropriate; accompanied by coercion; involving children of different ages or stages of development; or associated with emotional distress. Some, but not all, young people engaging in HSB come to the attention of authorities for investigation, prosecution or treatment. Depending on policy context, young people with HSB are those whose behaviour has resulted in a formal reprimand or warning, conviction for a sexual offence, or civil measures. Cognitive-behavioural therapy (CBT) interventions are based on the idea that by changing the way a person thinks, and helping them to develop new coping skills, it is possible to change behaviour.

OBJECTIVES

To evaluate the effects of CBT for young people aged 10 to 18 years who have exhibited HSB.

SEARCH METHODS

In June 2019, we searched CENTRAL, MEDLINE, Embase, 12 other databases and three trials registers. We also examined relevant websites, checked reference lists and contacted authors of relevant articles.

SELECTION CRITERIA

We included all relevant randomised controlled trials (RCTs) using parallel groups. We evaluated CBT treatments compared with no treatment, waiting list or standard care, irrespective of mode of delivery or setting, given to young people aged 10 to 18 years, who had been convicted of a sexual offence or who exhibited HSB.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We found four eligible RCTs (115 participants). Participants in two studies were adolescent males aged 12 to 18 years old. In two studies participants were males simply described as "adolescents." Three studies took place in the USA and one in South Africa. The four studies were of short duration: one lasted two months; two lasted three months; and one lasted six months. No information was available on funding sources. Two studies compared group-based CBT respectively to no treatment (18 participants) or treatment as usual (21 participants). The third compared CBT with sexual education (16 participants). The fourth compared CBT (19 participants) with mode-deactivation therapy (21 participants) and social skills training (20 participants). Three interventions delivered treatment in a residential setting by someone working there, and one in a community setting by licensed therapist undertaking a PhD. CBT compared with no treatment or treatment as usual Primary outcomes No study in this comparison reported the impact of CBT on any measure of primary outcomes (recidivism, and adverse events such as self-harm or suicidal behaviour). Secondary outcomes There was little to no difference between CBT and treatment as usual on cognitive distortions in general (mean difference (MD) 1.56, 95% confidence interval (CI) -11.54 to 14.66, 1 study, 18 participants; very low-certainty evidence), assessed with Abel and Becker Cognition Scale (higher scores indicate more problematic distortions); and specific cognitive distortions about rape (MD 8.75, 95% CI 2.83 to 14.67, 1 study, 21 participants; very low-certainty evidence), measured with the Bumby Cardsort Rape Scale (higher scores indicate more justifications, minimisations, rationalisations and excuses for HSB). One study (18 participants) reported very low-certainty evidence that CBT may result in greater improvements in victim empathy (MD 5.56, 95% CI 0.94 to 10.18), measured with the Attitudes Towards Women Scale, compared with no treatment. One additional study also measured this, but provided no usable data. CBT compared with alternative interventions Primary outcomes One study (59 participants) found little to no difference between CBT and alternative treatments on post-treatment sexual aggression scores (MD 0.09, 95% CI -0.18 to 0.37, very low-certainty evidence), assessed using Daily Behaviour Reports and Behaviour Incidence Report Forms. No study in this comparison reported the impact of CBT on any measure of our remaining primary outcomes. Secondary outcomes One study (16 participants) provided very low-certainty evidence that, compared to sexual education, mean cognitive distortions pertaining to justification or taking responsibility for actions (MD 3.27, 95% CI -4.77 to -1.77) and apprehension confidence (MD 2.47 95% CI -3.85 to -1.09) may be lower in the CBT group. The same study indicated that mean cognitive distortions pertaining to social-sexual desirability may be lower in the CBT group, and there may be little to no difference between the groups for cognitive distortions pertaining to inappropriate sexual fantasies measured with the Multiphasic Sex Inventory.

AUTHORS' CONCLUSIONS

It is uncertain whether CBT reduces HSB in male adolescents compared to other treatments. All studies had insufficient detail in what they reported to allow for full assessment of risk of bias. 'Risk of bias' judgements were predominantly rated as unclear or high. Sample sizes were very small, and the imprecision of results was significant. There is very low-certainty evidence that group-based CBT may improve victim empathy when compared to no treatment, and may improve cognitive distortions when compared to sexual education, but not treatment as usual. Further research is likely to change the estimate. More robust evaluations of both individual and group-based CBT are required, particularly outside North America, and which look at the effects of CBT on diverse participants.

MEGA ♪ : Empirical Findings on the Preternatural: Sexually Violent and Predatory Sexually Violent Youth

Applied are empirical findings from two major studies employing the ecologically framed MEGA ♪ risk assessment tool: MEGA ♪ Combined Samples Studies (N = 3901 [1979-2017] (Miccio-Fonseca 2017a, d) and MEGA ♪ Combined Cross Validation Studies (N = 2717). Samples consisted of male, female, and transgender-female sexually abusive youth, ages 4-19, including youth with low intellectual functioning of borderline or low average. Findings further support a previously presented nomenclature identifying two subsets overlooked by most contemporary risk assessment tools: sexually violent and predatory sexually violent youth (Miccio-Fonseca and Rasmussen Journal of Aggression Maltreatment & Trauma, 18, 106-128, 2009, 2014). MEGA ♪ Studies provided normative data, with cut-off scores (calibrated) according to age and gender, establishing four risk levels: Low, Moderate, High, and Very High. The fourth risk level, Very High, sets MEGA ♪ apart from other risk assessment tools for sexually abusive youth, which are limited to three risk levels. Very High risk level definitively identifies the most dangerous youth, thus empirically supporting the nomenclature of sexually violent and predatory sexually violent youth.

Risk Assessment of Adolescents with Intellectual Disabilities Who Exhibit Sexual Behavior Problems or Sexual Offending Behavior

Adolescents with intellectual disabilities are known to engage in various sexual behavior problems or sexual offending behaviors. This article provides a review of important aspects of risk assessment within the context of a broader, more comprehensive and holistic assessment of these individuals. Pertinent risk and sexual interest assessment tools are identified along with their strengths and limitations. Issues that are often unattended to are addressed, including consideration of the behavioral implications of the young person's diagnosis and level of cognitive functioning, need for sexual knowledge and sexual interest assessment, and issues related to making a mental health diagnosis. Recommendations for future research are also offered.

Scientific Evolution of Clinical and Risk Assessment of Sexually Abusive Youth: A Comprehensive Review of Empirical Tools

Risk assessment of sexually abusive youth is a specialty, which ideally includes a clinical assessment (e.g., psychological evaluation) utilizing a validated risk assessment tool. This article reviews tools for assessing sexual improprieties and/or sexually abusive behaviors in youth: JSORRAT-II, J-SOAP-II, J-RAS, AIM2, and MEGA^♪,1 and a clinical assessment tool, MIDSA. Untested, structured, clinical checklists with face validity, J-RAT-4 and PROFESOR, are included. The authors also highlight clinical dilemmas using "utility tools" (i.e., polygraph and plethysmograph) with sexually abusive youth. The comprehensive review sustains a twenty-first-century New Paradigm of inclusive ecologically based, developmentally and gender-sensitive assessment tools that definitively and accurately assess risk and protective factors of sexually abusive youth.

Comparing Predictive Validity of JSORRAT-II and MEGA♪ With Sexually Abusive Youth in Long-Term Residential Custody

This 6-year prospective study is the first to compare two psychometrically sound risk assessment tools for sexually abusive youth: JSORRAT-II and MEGA^♪. Cross-validated on representative samples of over 500 youth, these measures have cutoff scores, allowing for a more exact assessment of risk. Study sample consisted of 129 male adjudicated adolescents housed in a secured residential treatment facility for sexually abusive youth. Receiver operating characteristic (ROC) analysis showed that MEGA^♪ Risk Scale was mildly predictive of sexual recidivism over a 6-year period (mean follow-up = 15.6 months)-area under the curve (AUC) = .67; 95% confidence interval [CI] = [0.52, 0.82]; p < .015. JSORRAT-II was not predictive (AUC = .57; 95% CI = [0.42, 0.72]; p < .297). The study contributes to scant literature on the most contemporary, statistically robust risk assessment tools for sexually abusive youth.

The Allocation of Sexually Transgressive Juveniles to Intensive Specialized Treatment: An Assessment of the Application of RNR Principles

The aim of this study was to compare results of and develop guidelines for mandatory allocation of sexually transgressive juveniles to Multisystemic Therapy - Problem Sexual Behavior (MST-PSB), Secure Youth Care (SYC), or Forensic Youth Care (FYC), based on the risk-need-responsivity model. Results of current allocation showed a population with relatively less treatment needs to receive community-based MST-PSB, compared with populations receiving residential SYC and FYC. Furthermore, estimated recidivism risk levels did not always support the need for risk reduction by the imposition of limitation of freedom of movement and maximum supervision, provided by all three treatment modalities. Based on the assessed sexual recidivism risk, 38% of the juveniles in FYC, 7% in SYC, and 24% in MST-PSB received treatment that was too intensive, which is considered detrimental to motivation and development. Future allocation practices could benefit from assessing treatment needs and recidivism risk, by use of an actuarial tool.

The Influence of Age and Sexual Drive on the Predictive Validity of the Juvenile Sex Offender Assessment Protocol-Revised

The Juvenile Sex Offender Assessment Protocol-Revised (J-SOAP-II) is the most commonly used measure in the assessment of recidivism risk among juveniles who have committed sexual offenses (JSOs), but mixed support exists for its predictive validity. This study compared the predictive validity of the J-SOAP-II across two offender characteristics, age and sexual drive, in a sample of 156 JSOs who had been discharged from a correctional facility or a residential treatment program. The J-SOAP-II appeared to be a better predictor of sexual recidivism for younger JSOs (14-16 years old) than for older ones (17-19 years old), with significant differences found for the Dynamic Summary Scale and Scale III (Intervention). In addition, several of the measure's scales significantly predicted sexual recidivism for JSOs with a clear pattern of sexualized behavior but not for those without such a pattern, indicating that the J-SOAP-II may have greater clinical utility for JSOs with heightened sexual drive. The implications of these findings are discussed.

Changes in J-SOAP-II and SAVRY Scores Over the Course of Residential, Cognitive-Behavioral Treatment for Adolescent Sexual Offending

Although the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II) and the Structured Assessment of Violence Risk in Youth (SAVRY) include an emphasis on dynamic, or modifiable factors, there has been little research on dynamic changes on these tools. To help address this gap, we compared admission and discharge scores of 163 adolescents who attended a residential, cognitive-behavioral treatment program for sexual offending. Based on reliable change indices, one half of youth showed a reliable decrease on the J-SOAP-II Dynamic Risk Total Score and one third of youth showed a reliable decrease on the SAVRY Dynamic Risk Total Score. Contrary to expectations, decreases in risk factors and increases in protective factors did not predict reduced sexual, violent nonsexual, or any reoffending. In addition, no associations were found between scores on the Psychopathy Checklist:Youth Version and levels of change. Overall, the J-SOAP-II and the SAVRY hold promise in measuring change, but further research is needed.

Validity of the Youth Psychopathic Traits Inventory-Short Version in Justice-Involved and At-Risk Adolescents

The current study examined the reliability and validity of the Youth Psychopathic Traits Inventory-Short Version (YPI-S) in two different samples of at-risk adolescents enrolled in a residential program ( n = 160) and at a detention facility ( n = 60) in the United States. YPI-S scores displayed adequate internal consistency and were moderately associated with concurrent scales on other self-report psychopathy measures and externalizing behaviors. YPI-S scores were moderately related to interviewer-ratings of the construct using the four-factor model of the Psychopathy Checklist: Youth Version. Findings suggest that the YPI-S may be a clinically useful and valid tool for the assessment of psychopathic traits in juvenile settings. This may be particularly true given the differential predictive utility of each of its dimensions.

Juvenile Sex Offenders

Sexual offending by juveniles accounts for a sizable percentage of sexual offenses, especially against young children. In this article, recent research on female juvenile sex offenders (JSOs), risk factors for offending in juveniles, treatment, and the ways in which these youth may differ from general delinquents will be reviewed. Most JSOs do not go on to develop paraphilic disorders or to commit sex offenses during adulthood, and as a group, they are more similar to nonsexual offending juvenile delinquents than to adult sex offenders. Recent research has elucidated some differences between youth who commit sex offenses and general delinquents in the areas of atypical sexual interests, the use of pornography, and early sexual victimization during childhood.

Effects of School-Based Risk and Protective Factors on Treatment Success Among Youth Adjudicated of a Sexual Crime

Youth with sexually problematic behaviors are impacted by the reciprocal interplay between individual characteristics and the key social and ecological systems in which they are embedded. The paucity of research on protective factors mitigating risks within various socioecological systems is of concern, as the school is one such system that has been overlooked. This study retroactively investigated probation files among youth who were adjudicated of a sexual crime (N = 85) to determine how school-level variables are associated with treatment completion. A sequential logistical regression model revealed reduced odds for school-based risk factors and a greater proportion of variance explained when school-based protective factors were included. Implications and research considerations are discussed.

Juvenile Sex Offenders

Public policy has tended to treat juvenile sex offenders (JSOs) as adult sex offenders in waiting, despite research that contradicts this notion. Although as a group, JSOs are more similar to general delinquents than to adult sex offenders, atypical sexual interests and sexual victimization during childhood may be a pathway for sexual offending that differentiates some JSOs from their nonsexually delinquent peers. Developmental considerations must be considered in risk assessment evaluations of these youth. This article reviews theories of sexual offending in youth, risk factors for juvenile offending and reoffending, psychopathology in JSOs, risk assessment, and treatment.

The World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for the treatment of adolescent sexual offenders with paraphilic disorders

The primary aim of these guidelines was to evaluate the role of pharmacological agents in the treatment of adolescents with paraphilic disorders who are also sexual offenders or at-risk of sexual offending. Psychotherapeutic and psychosocial treatments were also reviewed. Adolescents with paraphilic disorders specifically present a different therapeutic challenge as compared to adults. In part, the challenge relates to adolescents being in various stages of puberty and development, which may limit the use of certain pharmacological agents due to their potential side effects. In addition, most of the published treatment programmes have used cognitive behavioural interventions, family therapies and psychoeducational interventions. Psychological treatment is predicated in adolescents on the notion that sexually deviant behaviour can be controlled by the offender, and that more adaptive behaviours can be learned. The main purposes of these guidelines are to improve the quality of care and to aid physicians in their clinical decisions. These guidelines brought together different expert views and involved an extensive literature research. Each treatment recommendation was evaluated and discussed with respect to the strength of evidence for efficacy, safety, tolerability and feasibility. An algorithm is proposed for the treatment of paraphilic disorders in adolescent sexual offenders or those who are at risk.

Protective factors and recidivism in accused juveniles who sexually offended

To date, research on juvenile sexual offender recidivism has tended to focus on risk factors rather than protective factors. Therefore, very little is known about protective factors in the population of juveniles who sexually offended. The aim of the present study was to examine the impact of protective factors on non-recidivism in a sample of accused juveniles who sexually offended (N = 71) in a mean follow-up period of 47.84 months. Protective factors were measured with the Protective Factor Scale of the Structured Assessment of Violence Risk in Youth (SAVRY), and the Structured Assessment of PROtective Factors for violence risk (SAPROF). Criminal charges served as recidivism data. The internal scale of the SAPROF, in particular, yielded moderate predictive accuracy for the absence of violent and general recidivism, though not for the absence of sexual recidivism. No protective factor of the SAVRY did reveal predictive accuracy regarding various types of the absence of recidivism. Furthermore, protective factors failed to achieve any significant incremental predictive accuracy beyond that captured by the SAVRY risk factors alone. The potential therapeutic benefit of protective factors in juvenile sexual offender treatment is discussed.

Self-reported psychopathic traits in sexually offending juveniles compared with generally offending juveniles and general population youth

The aim of the current study is to gain a better insight into the relationship between sexually aggressive behaviour and psychopathy in youths; juveniles who sexually offended (JSOs) were compared with generally offending youths and a general population group. Seventy-one JSOs, 416 detained general offenders, and 331 males from the general population were assessed by means of the Youth Psychopathic traits Inventory (YPI), a self-report instrument. Sexually and generally offending juveniles had significantly lower levels of self-reported psychopathic traits than youths from the general population. Juvenile sexual offenders and generally offending juveniles did not differ in self-reported psychopathic traits. Furthermore, no differences in self-reported psychopathic traits were found between subgroups of JSOs (i.e., child molesters, solo offenders, and group offenders). The finding that self-reported psychopathic traits are less prevalent in offending juveniles than in general population youths raises questions about the usefulness of the YPI when comparing psychopathic traits between clinical samples and general-population samples.

Die Einschätzung des Rückfallrisikos bei sexuell auffälligen Kindern und Jugendlichen anhand standardisierter Prognoseinstrumente

In der vorliegenden Untersuchung wurde überprüft, ob standardisierte Prognoseinstrumente in der Lage sind, erneute Auffälligkeiten in einer Stichprobe von sexuell auffällig gewordenen Kindern und Jugendlichen (N = 80; als Einschlusskriterium musste keine Verurteilung erfolgt sein) vorherzusagen. Eingesetzt wurden die international als etabliert geltenden Verfahren Structured Assessment of Violence Risk in Youth (SAVRY), Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR) und Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II). Die Ergebnisse der vorliegenden Studie zeigen, dass die ursprünglich für junge bzw. jugendliche Sexualstraftäter entwickelten Instrumente auch bei einer Stichprobe sexuell auffälliger Minderjähriger in der Lage sein können, erneute auffällige Handlungen vorherzusagen. Dies gelang allerdings lediglich im Hinblick auf die allgemeine und die gewalttätige Auffälligkeit, während der Nachweis der prädiktiven Validität für erneute sexuelle Auffälligkeiten nicht gelang.

Recent research related to juvenile sex offending: findings and directions for further research

Serious scholarly inquiry into juvenile sex offending represents a relatively new field, dating from the mid 1940s. During the next 4 decades, a mere handful of articles exploring aspects of juvenile sex offending were added to the available literature. By the 1980s, however, the literature began to increase rapidly, a trend that continues today. The purpose of this article is a focused review of the juvenile sex offender literature cited in PubMed over the last 5 years (2009-2013). The authors have chosen studies that will bring readers up to date on research they believe impacts our current understanding of best practices in the management of juvenile sex offending. For convenience, our review is organized into topical categories including research into characteristics and typologies of juvenile sex offenders, risk assessment and recidivism, assessment and treatment, the ongoing debate about mandatory registration of sex offenders as it applies to juveniles, and other thought provoking studies that do not fit neatly into the aforementioned categories. The studies included contain findings that both reinforce and challenge currently held notions about best practices concerning treatment and public policy, suggesting that our knowledge of the field continues to evolve in important ways.
