The aim of this paper is to provide up‐to‐date discussion of the types of factors used to assess sexual offenders risk.

The current status of the factors used to assess risk in sexual offenders is examined.

Risk factors broadly fall into two categories: static factors (i.e. generally unchangeable information such as previous offence history) from which a number of actuarial scales have been developed; and dynamic factors (i.e. psychological dispositions) that are typically identified in treatment. It is suggested that these risk factors are artefacts of the same behavioural and psychological vulnerabilities at different stages of assessment, with static factors acting as markers for underlying dispositions, while dynamic factors are the underlying dispositions.

The paper discusses in some detail the status of age as a risk factor, where even though it is typically considered a static risk factor in a number of actuarial scales (allowance typically being made if individuals are over/under 25), there is a dynamic element (i.e. change with age or the passage of time) to this aspect of assessment.

This paper may be useful to practitioners working in the field, in terms of providing a useful heuristic framework for risk conceptualisation.

Risk assessment studies involving recidivism in sex offenders with intellectual disabilities (SOIDs) continue to be scarce, limited and producing mixed results. This study aims (to test the ability ...) to test the ability of one such instrument (the Static-99R) to predict intramural sexual and violent incidents involving members of this group.

The Static-99R was prospectively scored for 38 SOIDs. Occurrences of any violent or sexual incident and/or illegal sexual behaviour were recorded during a minimum period of six months. Predictive accuracy was analysed using several performance indicators.

The Static-99R significantly predicted sexual incidents (area under the curve = 0.70) but failed to predict violent and illegal sexual incidents. Regarding illegal sexual incidents, the instrument was better at detecting low-risk individuals than high-risk offenders.

Risk assessment studies, both in offenders with and without an intellectual disability (ID), rarely use multiple accuracy estimates. The current study used both discrimination and calibration indicators to evaluate the ability of the Static-99R to detect low- and high-risk offenders.

While there is a significant proportion of people with a mild intellectual disability (MID) or borderline intellectual functioning (BIF) who commit sexual offenses, little research has focused on the risk factors for sexual recidivism in people with MID-BIF. The purpose of this paper is to compare the scores on the STATIC-99R and STABLE-2007 between persons with sexual offense histories with and without MID-BIF.

Data using the STATIC-99R and STABLE-2007 were collected in 85 male patients divided into an MID-BIF group (IQ 50–85, n=50) and comparison group (IQ>95, n=35).

The MID-BIF group and comparison group did not differ significantly on the static risk factors and total score of the STATIC-99R. However, of the 13 dynamic risk factors of the STABLE-2007, the MID-BIF group scored significantly higher on the items Impulsive acts, Poor problem solving skills and Lack of concern for others, while the comparison group scored significantly higher on the item Deviant sexual preference.

The higher score on a number of dynamic risk factors for patients with MID-BIF could partly be explained by the characteristics associated with MID-BIF. Although dynamic criminogenic risk factors which are usually identified as targets for treatment appear the same for people with and without MID-BIF who commit sexual offenses, adaptations to the modality of treatment will still need to be made for people with MID-BIF.

The assessment of risk of recidivism in sexual offenders is fundamental to clinical practice. It is widely accepted that, compared with actuarial measures of risk, unaided clinical judgment has generally been found to be of low reliability. Consequently, the literature has shown a surge in actuarial measures. However, a major difficulty in assessing risk in sex offenders is the low base rate, leading to an increased likelihood of making a false positive predictive error. To overcome this, risk assessment studies are increasingly using the receiver operating characteristic (ROC), which displays the relationship between level of risk and decision choice. This note summarises the methodological issues in measuring predictive accuracy in assessing risk of re‐offending in sexual offenders, and identifies from the literature both static and dynamic risk factors associated with sexual offence recidivism.

The purpose of this paper is to summarise the available risk and assessment tools for child abuse material (CAM) offenders. Noting the rise of internet-based offences surrounding CAM, it has been proposed that there may be substantial differences between internet only (IO) offenders, contact only and mixed profile sexual offenders.

Through online searches, risk assessment tools for sexual offenders were identified. Scoring manuals were consulted for applicability to IO offenders.

Nine risk assessment tools for sexual offenders were included. Risk assessment tools for sexual offenders use cautionary language regarding the application of sexual offence risk assessment tools to IO offenders. An additional five tools were identified specifically addressing IO offenders. Three of these tools address risk assessment and two assess cognitions and behaviours.

Limitations include the identification of static and dynamic risk factors and the application of structured professional judgement.

By drawing together existing tools and recommendations for use with the IO offender population, a gap is identified for CAM specific risk assessment tools.

Appropriate risk assessment, case planning and treatment will contribute to the appropriate management and treatment of the IO offender population.

In this chapter, I analyse the ethics of organisations assessing applicants based on group risk statistics; for example, parole boards consider information predicting recidivism risk, and employers want to minimise the risk of selecting lower-productivity employees. The organisational rejection of applicants from risky groups is explored as a form of discrimination to help identify the distinct ethical implications for applicant autonomy from the use of group risk statistics. Contra arguments from Schoeman (1987) and Schauer (2003), I argue that there is a substantive difference between assessing applicants directly through group statistics rather than including ‘individualised’ evidence. This difference impacts on the agency of applicants in the process. As organisations have reason to statistically assess applicants, some considerations for increasing applicant agency in the process are suggested. These include focusing on the nature of the factors used to assess applicants (static or dynamic), the transparency of the process to applicants, and the use of statistics specific to individuals.

Recently, correctional agencies have argued that there are differences between factors influencing men and women’s involvement in the criminal justice system. The purpose of this paper is to examine the validity of a gender-informed risk/need assessment tool.

The sample consisted of 620 women offenders admitted to federal Canadian custody, as well as a matched-comparison group of 647 men. Items were selected from routine assessments in an administrative database based on an extensive literature review of factors related to criminal risk for women.

Results showed that the items included in this assessment and the overall rating of risk/need significantly predicted any return to custody for both women and men. As well, ratings incrementally predicted any return to custody over and above other established tools.

The gender-informed risk/need assessment tool, informed by the literature, performed well for both men and women. The research highlights the complementary, not competing, perspectives of gender-neutral and gender-responsive risk and need factors.

Factors commonly considered gender-salient predicted risk for men and women. The present study demonstrates that risk assessments tools for men and women should look beyond the factors routinely assessed in the research to identify novel dynamic factors that contribute to risk for men and women and could be targeted for intervention.

The production of sleeve grouting in prefabricated construction is routinely plagued by a variety of factors, and lack of mass data and complex environmental conditions over time make problems inevitable. Thus, a dynamic risk control system is a valuable support for the successful completion of the sleeve grouting process. This study aims to develop an entropy-based sleeve grouting risk dynamic control system.

First, static risk assessment was conducted through the structured interview survey using the entropy weight method, followed by a dynamic risk control technique, where indicators were simulated through system dynamics containing causal loop diagrams and stock-and-flow diagrams.

Finally, three types of risk control models, namely, “tortuous type”, “stable type” and “peak loop type”, were developed in the entropy-based sleeve grouting risk dynamic control system and simulated using system dynamics in a real case.

Compared to traditional sleeve grouting risk management, the developed system enabled dynamic control over time.

The purpose of this paper is to examine the extent to which risk is addressed in the risk management planning process of those convicted of sexual offending.

Data were collected from a risk assessment and management system called the Offender Assessment System (OASys), used by the National Offender Management Service, in England and Wales. The records of 216 clients were accessed and each risk management plan analysed. The study aimed to understand if first, general and sexual risk factors identified by assessors were recorded and detailed in subsequent plans; second, if specialist sexual offending risk assessment tools were used to inform risk management strategies; and third, if both a balance of control and support mechanisms were in place to tackle identified risk and needs of clients.

Inconsistencies were found in relation to practitioners transposing risks identified, into the subsequent risk management plans. Strategies were therefore deemed, inadequate as there was a significant omission of the use of specialist sexual risk assessment tools to inform and ensure risk assessment to be robust. In addition risk management plans were often overbearing in nature, as assessors tended to utilise control strategies to assist the reintegration process, in contrast to a combination of both control and support.

This sample was taken from only one probation trust in England and Wales. The findings might therefore be unique to this organisation rather than be representative of national practice. This study should therefore, be replicated in a number of other probation areas. In addition, it is important to note that this study only reviewed one electronic tool used by practitioners. Therefore, while it might appear for example that the RM2000 tool was not routinely completed; this cannot be assumed as practitioners might have adopted local custom and practice, recording RM2000 scores elsewhere.

These findings highlight the need for some understanding as to why there is a lack of consistency throughout the risk management planning process. Practitioners should receive ongoing risk management training, development and supportive supervision. In particular, practitioners require supervision that supports and develops their skills when applying RM2000 classifications to their clients’ risk management plans. Likewise initiatives which develop practitioner’s awareness and application of strengths based approaches such as the Good Lives Model should be encouraged. These will help practitioners develop plans that address both the risks while supporting their development of the strengths a client presents.

To the authors’ knowledge, this is the first study of its kind, which examines the risk management plans of those convicted of sexual offending, completed by practitioners in England and Wales using the OASys tool.

As recently highlighted by Creaby-Attwood and Allely (2017), it is crucial that the possible innate vulnerabilities that contributed to sexual offending behaviour in an individual with an autism spectrum disorder (ASD) are taken into consideration for the application of a diversion programme to avoid the stigma of a criminal conviction or during sentencing for a non-custodial outcome. Specifically, in those defendants with a diagnosis of what used to be referred to as Asperger’s syndrome (AS) and now is recognised as an ASD and who are charged and convicted of a non-contact sexual offense, education and mental health intervention will best serve the interests of justice. The paper aims to discuss this issue.

This paper focusses on one particular type of sexual offending behaviour, namely, possession of child pornography. A systematic PRISMA review was conducted.

The authors linked examples of child pornography in the research literature to the ASD symptomology and describe how the symptomology explains such behaviour as not reflecting actual sexual deviance.

Downloading and viewing of child pornography by individuals with ASD has received relatively little research outside the mental health field. This review is of particular importance to those in the criminal justice system who may not have much knowledge and understanding of ASD. It is suggested that diversion programmes and mental health courts should be set up for this particular population charged with this particular crime in mind so that the necessary treatment/intervention/support and care can be given to this particular group.
