Adolescents who have sexually offended: is phallometry valid?

Mixed Emotions: An Incentive Motivational Model of Sexual Deviance

Sexual offending behavior is a complex and multifaceted phenomenon. Most existing etiological models describe sexual offending behavior as a variant of offending behavior and mostly include factors referring to disinhibition and sexual deviance. In this article, we argue that there is additional value in describing sexual offending behavior as sexual behavior in terms of an incentive model of sexual motivation. The model describes sexual arousal as an emotion, triggered by a competent stimulus signaling potential reward, and comparable to other emotions coupled with strong bodily reactions. Consequently, we describe sexual offending behavior in terms of this new model with emphasis on the development of deviant sexual interests and preferences. Summarized, the model states that because sexual arousal itself is an emotion, there is a bidirectional relationship between sexual self-regulation and emotional self-regulation. Not only can sex be used to regulate emotional states (i.e., sexual coping), emotions can also be used, consciously or automatically, to regulate sexual arousal (i.e., sexual deviance). Preliminary support for the model is drawn from studies in the field of sex offender research as well as sexology and motivation research.

Validity in Phallometric Testing for Sexual Interests in Children: A Meta-Analytic Review

Valid assessment of pedohebephilic interests (i.e., sexual interest in children) is fundamental to forensic clinical practice. Phallometric testing-which measures changes in penile circumference or volume, while stimuli depicting different ages and sexual activities are presented-is widely used in clinical and research settings to detect such interests. This meta-analysis summarizes studies comparing sexual offenders against children and various types of controls on phallometric tests for pedohebephilic interests (37 samples; N = 6,785) and studies examining the relationship between phallometric test scores and sexual reoffending (16 samples; N = 2,709). The findings suggest that several phallometric testing procedures are valid indicators of pedohebephilic interest. Certain methodological features of phallometric tests were associated with greater validity, such as, slide or audio-plus-slide stimuli and z-score-based indices. In addition, phallometric tests for pedohebephilic, pedophilic, and hebephilic interests predicted sexual reoffending which provides further evidence that phallometric test scores are valid indicators of sexual interest in children. In general, the interpretation of phallometric test scores as indicators of pedohebephilic interests is supported.

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 = 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.

Prevention-enhancing interactions: a Critical Interpretive Synthesis of the evidence about children who sexually abuse other children

There is a growing interest in English-speaking jurisdictions, including Australia, North America, Canada, the United Kingdom and New Zealand, about the prevention of sexual abuse perpetrated by children against other children. The aim of this review was to identify opportunities for research, policy and practice which could enhance the prevention agenda relating to the perpetration of sexual abuse by children through conducting a Critical Interpretive Synthesis. Eleven electronic databases were searched in the period from 22 April to 23 May 2013 and included: SocINDEX, Social Services Abstracts, Applied Social Sciences Index and Abstracts, Family and Society Studies Worldwide, Project Muse, PsychINFO, Family and Society Plus, Jstor, Expanded Academic ASAP, Web of Science and Google Scholar. Key individual journals were also searched, including Child Abuse and Neglect and the Journal of Interpersonal Violence, as well as the grey literature. The search was guided by the research question: How could the prevention agenda relating to sexual abuse perpetrated by children be enhanced? The systematic literature search yielded 3323 titles, and 34 of these papers were included in the final synthesis. The authors identified five domains operating in the evidence base: characteristics, causes, communications, interventions and treatments. A synthesising construct emerged from the review: prevention-enhancing interactions. This construct referred to the potential for enhancing the prevention agenda which exists as the evidence domains interact with one another, and with the public health model of prevention. The authors consider this review to be a timely contribution to the current agenda pertaining to sexual abuse perpetrated by children. It provides researchers, policy makers and practitioners in the field with an evidence-informed conceptualisation of opportunities for enhancing prevention work.

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.

Assessing Sexual Interest in Adolescents Who Have Sexually Offended

Adolescents who have sexually offended have unique treatment needs. For mental health professionals to adequately address these unique needs, further research is necessary. To that end, we explored the assessment of sexual interest (which may play an integral role in understanding potential for sexual reoffending) in a sample of 103 male adolescents who have sexually offended. We compared results from a physiological assessment (MONARCH 21 penile plethysmography [PPG]) and an actuarial assessment (Screening Scale for Pedophilic Interest [SSPI]), plus data from an unobstrusive assessment (Affinity, a viewing time measure) in a smaller subsample of 16 male adolescents. One finding that has particular relevance for clinical assessment is that the SSPI may have limited utility with adolescents. We also found evidence for some overlap between data from PPG and viewing time assessments, although whether or not PPG data are ipsatized may affect relationships with other assessment modalities.

Youth who sexual offended: primary human goods and offense pathways

There has been an increased focus on understanding youth sexual offending in recent years, but there has been limited empirical research on the causes, pathways, and treatment of youth who have sexually offended-especially within a non-Western context. The Good Lives and Self-Regulation Models have often been used to understand and rehabilitate adult sexual offenders, but (unfortunately) there is scant research on youth who sexually offended using these models. The present study aims to describe the different primary goods that are associated with youth sexual offending behaviors in an Asian context. In addition, the study sought to explore whether the age of victim (child vs. nonchild) and nature of sexual offense (penetrative vs. nonpenetrative) influenced the youth's engagement in offense pathways. The results suggest that pleasure, relatedness, and inner peace were the primary human goods that were most sought after by a sample of 168 youth who sexually offended in Singapore. In addition, offender classification (in relation to the age of victim and nature of sexual offense) influenced the pathways to sexual offending. Therefore, these findings have important clinical implications for assessment, management, and intervention planning for youth who sexually offended.

Assessment of the paraphilias

Paraphilias are recurrent, persistent, and intense sexual interests in atypical objects or activities. The most commonly encountered paraphilias in sexological or forensic settings are pedophilia, sexual sadism, exhibitionism, and voyeurism. Paraphilias are often comorbid with other sexual, mood, and personality disorders. Assessment and diagnosis require an integration of multiple sources of clinical information, given the limits and biases of self-report (through clinical interview or questionnaires). Clinicians ideally have access to more objective assessment methods, such as phallometric testing of sexual arousal. The accurate assessment and diagnosis of paraphilias is essential to effective treatment and management.

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.
