Does the polygraph lead to better risk prediction for sexual offenders?

The polygraph is receiving increased attention surrounding its ability to facilitate more honest disclosures from sexual offenders concerning risk-related information (e.g., historical risk factors and acute-dynamic risk factors). In addition, the polygraph has become accepted as a standard containment tool in the US, although UK professionals appear to have taken a more cautionary approach. The aim of this review is to provide a basic overview of current risk assessment procedure in the absence of the polygraph, and then to investigate studies that use the polygraph to enhance sexual offenders' risk assessments. Specifically, studies examining historical risk factors, stable-dynamic risk factors, and acute-dynamic risk factors are examined and evaluated. We conclude that there is reasonable evidence supporting polygraph use in some areas of risk assessment. However, the vast majority of studies suffers from serious confounds that should be taken into account by professionals who use the polygraph as a standard practice in sexual offender risk assessment and management. Finally, the future of the polygraph is discussed in light of the presented empirical evidence.

A descriptive model of the offense process for female sexual offenders

Although considerable efforts have been made to develop and validate etiological models of male sexual offending, no theory is available to guide research or practice with female sexual offenders (FSOs). In this study, the authors developed a descriptive, offense process model of female sexual offending. Systematic qualitative analyses (i.e., grounded theory) of 22 FSOs' offense interviews were used to develop a temporal model documenting the contributory roles of cognitive, behavioral, affective, and contextual factors in female sexual abuse. The model highlights notable similarities and divergences between male and female sexual offenders' vulnerability factors and offense styles. In particular, the model incorporates male co-offender and group co-offender influences and describes how these interact with vulnerability factors to generate female sexual offending. The gender-specific research and clinical implications of the model are discussed.

Pathways to female sexual offending : approach or avoidance?

This study forms the second part of a larger investigation into the offence process characteristics of female sexual offenders (FSOs). In the first part - documented in Gannon, Rose, and Ward (Sexual Abuse: A Journal of Research and Treatment, 20, 352-374, 2008) - we described the development of the Descriptive Model of Female Sexual Offending (DMFSO); an offence process model developed using Grounded Theory methodology to describe the sequence of cognitive, affective, behavioural and contextual factors generating female-perpetrated sexual abuse. The second study described here examines the prevalence of specific pathways characterizing the 22 FSOs originally used to develop the DMFSO. Four individuals could not be assigned to a pathway due to lack of information (18% of the overall sample). However, for the remaining 18 participants, three stable pathways to female sexual offending were identified: Explicit Approach offenders (50%, n=9), who intended to offend, and explicitly planned their offence behaviours accordingly; Directed Avoidant offenders (28%, n=5), who did not intend to offend, but did so under the direction and coercion of a male accomplice; and Implicit Disorganized offenders (22%, n=4), who did not intend to offend (i.e. they engaged in minimal planning), but offended impulsively following severe self-regulatory failure. In this paper, we present the core characteristics defining each pathway, their associated demographic features, and discuss potential treatment implications.

The structural properties of sexual fantasies for sexual offenders : a preliminary model

While the phenomenon of sexual fantasy has been researched extensively, little contemporary inquiry has investigated the structural properties of sexual fantasy within the context of sexual offending. In this study, a qualitative analysis was used to develop a descriptive model of the phenomena of sexual fantasy during the offence process. Twenty-four adult males convicted of sexual offences provided detailed retrospective descriptions of their thoughts, emotions and behaviours—before, during and after their offences. A data-driven approach to model development, known as Grounded Theory, was undertaken to analyse the interview transcripts. A model was developed to elucidate the structural properties of sexual fantasy in the process of sexual offending, as well as the physiological and psychological variables associated with it. The Sexual Fantasy Structural Properties Model (SFSPM) comprises eight categories that describe various properties of sexual fantasy across the offence process. These categories are: origin, context, trigger, perceptual modality, clarity, motion, intensity and emotion. The strengths of the SFSPM are discussed and its clinical implications are reviewed. Finally, the limitations of the study are presented and future research directions discussed.

What were they thinking? An exploration of child sexual offenders' beliefs using a lexical decision task

Cognitive distortions have been afforded a key role in the offending behaviour of child sexual offenders. While the mechanisms underlying cognitive distortions are not fully understood, they are generally thought to reflect entrenched beliefs that distinguish child sexual offenders from other individuals. We investigated this hypothesis using a robust experimental technique called the lexical decision task. Child sexual offenders, offender controls, and non-offender controls completed a lexical decision task in which they responded to words that completed sentences in either an offence-supportive or nonoffence-supportive manner. Contrary to predictions, child sexual offenders did not respond faster to words that were consistent with offence-supportive beliefs, relative to controls. However, they did show accelerated recognition for word stems supporting external locus of control beliefs. These results highlight the need to use cognitive experimental methods to study child sexual offenders' beliefs, and the importance of investigating potential alternative drivers of cognitive distortions.

The effects of visual priming on information processing in child sexual offenders

Child sexual offenders are hypothesized to hold offence-supportive beliefs that set them apart from others. The current study seeks support for this view via a cognitive-experimental approach. Child sexual offenders and offender controls were exposed to pictures of semi-clothed children (priming condition) or clothed, mature adults (control condition). Participants then read ambiguous sentences describing children's actions that could be interpreted in a sexualized manner. Next, participants completed a surprise recognition test in which half the sentences were re-presented in an unambiguously sexual form, and half in an unambiguously non-sexual form. Contrary to hypotheses, primed and/or control child sexual offenders did not show a memory bias for sexualized sentences, suggesting that they did not interpret the original sentences in line with offence-supportive beliefs. Results raise questions about whether child sexual offenders universally hold abnormal beliefs that facilitate their offending. Results also highlight the need for further experimental research within this field.

What's in a measure? A multi-method study of child sexual offenders' beliefs

The hypothesis that child sexual offenders (CSOs) hold distorted, offence-supportive beliefs is usually investigated using interview and questionnaire techniques. However, in light of various problems associated with the use of these techniques, researchers are increasingly turning to cognitive-experimental approaches. To date, no study has examined potential differences in the nature of the beliefs that are revealed using interview, questionnaire, and experimental methods. In this study, data is gathered using these three methods and the results triangulated. CSOs are interviewed and the content categorised into five belief types. CSOs and offender controls then complete a questionnaire measure of offence-supportive beliefs and an experimental task (Rapid Serial Visual Presentation-Modified, or RSVP-M), which uses sentence reading times to explore content held in cognitive structures. As hypothesised, CSOs showed evidence of holding distorted beliefs according to the interview and questionnaire measures. Against predictions, however, CSOs did not show evidence of holding distorted belief structures on the RSVP-M task. In fact, the three methods showed no agreement regarding the belief types each CSO was deemed to hold. These results raise important questions about the phenomena and potential artefacts measured by each method.

Working positively with sexual offenders : maximizing the effectiveness of treatment

In this article, the authors draw on literatures outside sexual offending and make suggestions for working more positively and constructively with these offenders. Although the management of risk is a necessary feature of treatment, it needs to occur in conjunction with a strength-based approach. An exclusive focus on risk can lead to overly confrontational therapeutic encounters, a lack of rapport between offenders and clinicians, and fragmented and mechanistic treatment delivery. The authors suggest that the goals of sexual offender treatment should be the attainment of good lives, which is achieved by enhancing hope, increasing self-esteem, developing approach goals, and working collaboratively with the offenders. Examples are provided of how these targets may be met. When this is done within a therapeutic context where the treatment providers display empathy and warmth and are rewarding and directive, the authors suggest that treatment effects will be maximized.

The role of culture in understanding child sexual offending : examining feminist perspectives

Psychological theories on child sexual abuse continue to dominate etiological and rehabilitative approaches to understanding and treating sexually abusive behavior. However, even though psychological researchers are motivated toward development of comprehensive and highly integrated theories, there has been continued neglect of the cultural dimensions of child sexual abuse. Feminist theories of child sexual abuse have been particularly helpful in filling this explanatory gap, as they have persisted in locating sexually abusive behavior within a cultural context. In this paper we review and critique selected feminist theories on child sexual abuse with the aim of establishing their explanatory scope and utility. Overall, we found that feminist perspectives were useful in justifying and establishing social policies aimed at preventing the sexual abuse of children from ever commencing. However, despite this strength, they offer little guidance in the treatment of individual offenders.

Empathy and adolescent sexual offenders : a review of the literature

A significant proportion of sexual offenses has been found to be committed by adolescent offenders. Although there is overlap in the backgrounds of adolescent sexual offenders and juvenile delinquents, in recent times there has been an increased effort to identify and treat adolescent sexual offenders as a distinct population. Adolescent sexual offenders are thought to be empathy deficient, with empathy development a commonly defined treatment goal. There is confusion, however, as to whether such empathy deficits are general in nature, are towards certain groups of people, or are own victim-specific. This article provides a review of the literature concerning empathy and adolescent sexual offenders and, based on this assessment, recommendations are made for future research.

Punishment or therapy? The ethics of sexual offending treatment

The claim that sex offender treatment is a form of punishment and as such cannot be covered by traditional ethical codes is a controversial one. It challenges the ethical basis of current practice and compels clinicians to rethink the work they do with sex offenders. In this paper I comment on Bill Glaser's defence of that idea in a challenging and timely paper and David Prescott and Jill Leveson's rejection of his claims. First, I consider briefly the nature of both punishment and treatment and outline Glaser's argument and Prescott and Levenson's rejoinder. I then investigate what a comprehensive argument for either position should look like and finish with a few comments on each paper.

An integrated theory of sexual offending

This paper represents a first attempt to provide an integrated framework to explain the onset, development, and maintenance of sexual offending. According to the Integrated Theory of Sexual Offending (ITSO), sexual abuse occurs as a consequence of a number of interacting causal variables. We examine the factors that affect brain development (evolution, genetic variations and neurobiology) and ecological factors (social and cultural environment, personal circumstances, physical environment) and discuss how they impact upon core neuropsychological functions underpinning human action. The ITSO then explains how clinical symptoms arise from the interaction between these neurological systems and ecological factors. The capacity of the ITSO to incorporate competing theories of sexual offending is considered, and we end the paper by critically evaluating its usefulness in stimulating research and further theory development.

A human rights-based practice framework for sexual offenders

Human rights create a protective zone around people and allow them the opportunity to further their own valued personal projects without interference from others. In our view, the emphasis on community rights and protection may, paradoxically, reduce the effectiveness of sex offender rehabilitation by ignoring or failing to ensure that offenders' core human interests are met. In this paper we consider how rights-based values and ideas can be integrated into therapeutic work with sex offenders in a way that safeguards the interests of offenders and the community. To this end we develop a rights-based normative framework (the Offender Practice Framework: OPF) that is orientated around the three strands of justice and accountability, offender needs and risk, and the utilization of empirically supported interventions and strength-based approaches. We examine the utility of this framework for the different phases of sex offender practice.

Rehabilitation, etiology, and self-regulation : the comprehensive good lives model of treatment for sexual offenders

In this paper, we draw upon two sets of theoretical resources to develop a comprehensive theory of sexual offender rehabilitation named the Good Lives Model-Comprehensive (GLM-C). The original Good Lives Model (GLM-O) forms the overarching values and principles guiding clinical practice in the GLM-C. In addition, the latest sexual offender theory (i.e., the Integrated Theory of Sexual Offending; ITSO) provides a clear etiological grounding for these principles. The result is a more substantial and improved rehabilitation model that is able to conceptually link latest etiological theory with clinical practice. Analysis of the GLM-C reveals that it also has the theoretical resources to secure currently used self-regulatory treatment practice within a meaningful structure.

Beliefs, values, and action : the judgment model of cognitive distortions in sexual offenders

In this paper, we present the Judgment Model of Cognitive Distortions (JMCD), a new model of cognitive distortions that spans multiple levels of analysis and contains different types of judgments. This model proposes that cognitive distortions tend to cluster together in what we have termed Thematic Networks (TN): judgments about beliefs, values, and actions. We argue that the three sets of judgments cover all types of cognitive distortions apparent in sexual offenders including those revolving around content (i.e., asserting characteristics to people, the offender, the world) and cognitive operations (i.e., denial, minimization, rationalizations). Following a description of the JMCD, we demonstrate how it can account for the cognitive schemata identified in sexual offenders by researchers and clinicians. The paper concludes with a brief discussion of the clinical and research implications of the JMCD.
