The purpose of this paper is to examine the role of a variety of developmental factors on sexual homicide offenders (SHOs), while taking into account other components of sexual homicide theoretical models.

A series of logistic regression models are performed using a total of 616 incarcerated adult male sexual offenders from Canada to distinguish between three groups of sexual offenders, SHOs, violent non-homicidal sex offenders (NHSOs) and NHSOs.

Results indicate that contrary to theoretical models, experiences of victimization are not central to the development of SHOs. Instead, it is the adoption of various problematic behaviors in childhood that appear as most important in the etiology of this particular type of sexual crime. This suggests that the various existing theoretical models of sexual homicide need to be revised and/or tested with additional empirical data.

This is the first study to look at developmental factors using two control groups of NHSOs and violent NHSOs.

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 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.

Effective treatments for juvenile sexual offenders are needed to reduce the societal impact of sexual crimes. The purpose of this paper is to review the empirical literature on treatments for this clinical population.

The authors searched PsycInfo and MEDLINE (via PubMed) for studies that evaluated outcomes of treatments with juvenile sexual offenders.

There are a small but growing number of treatment studies (n=10) with juvenile sexual offenders, and all of these studies evaluated cognitive-behavioral therapy or multisystemic therapy for problem sexual behaviors. The results of these studies are promising, although conclusions about treatment effectiveness have been frequently limited by methodological problems.

The authors provide recommendations for treatment providers and policymakers to consider in their decisions about interventions for juvenile sexual offenders. Furthermore, the authors offer suggestions for researchers who seek to develop effective interventions targeting this clinical population.

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.

This paper reviews the literature on therapeutic process specific to sexual offender treatment. The general clinical literature emphasises the importance of therapist style, the client's perceptions, the therapeutic alliance and cohesiveness. We highlight the importance of therapist characteristics, group cohesion and emotion in effective treatment of sexual offenders. Implications for programming and research are emphasised.

The purpose of this paper is to investigate whether it is possible to identify different types of sadistic offenders within a sample of sexual homicide offenders (SHOs).

The study addresses this research question through the use of two-step hierarchal cluster analysis and binary logistic regression utilizing a sample of 350 cases of sexual homicide from Canada.

Results from cluster analysis show that three groups emerge: a non-sadistic group, a mixed group that show evidence of some sadistic behavior and a sadistic group that have high levels of sadistic behavior. Additionally, the sadistic cluster was more likely to destroy or remove evidence at the crime scene than the mixed and non-sadistic cluster and was more likely to leave the victim’s body at a deserted location than the non-sadistic cluster.

This is the first study to examine the dimensionality of sadism within a sample of SHOs.

Sex offender registration and notification act (SORNA) offenders are a source of scholarly study across the social, behavioral, forensic and legal sciences with the bulk of literature focusing on the legal standing and deterrent value of sexual offender registries. Less research focuses on the offending careers of current SORNA offenders relative to other types of sexual offenders whose current offense is not SORNA. The purpose of the current study is to examine this issue empirically.

Using cross-sectional data from a census of male federal offenders who ever perpetrated a sexual offense from the central USA between 2016 and 2020, the current study used t-tests, logistic regression and negative binomial regression to compare current SORNA offenders to other federal correctional clients in terms of their lifetime offending history, sexual violence and compliance on federal supervision.

Current SORNA offenders are significantly more severe and versatile in their sexual offending, have more extensive criminal careers and criminal justice system involvement, and exhibit significantly increased odds of revocation on supervised release despite controls for age, race and ethnicity. However, sensitivity models that specified the federal Post-Conviction Risk Assessment reduced the effects of SORNA status to non-significance in all models.

SORNA offenders are potentially a significant offender group with evidence of both and given their versatile and specialized lifetime offending and noncompliance on federal supervision. However, current SORNA status is rendered spurious once a risk assessment is controlled suggesting more research is needed to evaluate whether sex offender registries posit greater crime control benefit.

The main aim of this paper is to describe the content, structure and preliminary evaluation of a new Good Lives sexual offender treatment group (SOTG) for male mentally disordered offenders.

As evaluation and work on the SOTG is necessarily ongoing, case study descriptions of each patient who attended the SOTG and of their progress throughout SOTG are described.

Overall, the case study progress reports suggest that mentally disordered male patients made some notable progress on SOTG despite their differential and complex needs. In particular, attention to each patient's life goals and motivators appeared to play a key role in promoting treatment engagement. Furthermore, patients with lower intelligence quotient and/or indirect pathways required additional support to understand the links between the Good Lives Model (GLM) and their own risk for sexual offending.

Further evaluations of SOTG groups, that incorporate higher numbers of participants and adequate control groups, are required before solid conclusions and generalisations can be made.

Practitioners should consider providing additional support to clients when implementing any future SOTGs for mentally disordered patients.

This is the first paper to outline and describe implementation of the GLM in the sexual offender treatment of mentally disordered male patients group format. As such, it will be of interest to any professionals involved in the facilitation of sexual offender treatment within this population.

The purpose of this paper is to increase our understanding of the role of mental disorder in sexual offending as well as identifying innovations in assessment and treatment with offenders who present with these typically complex risks and needs.

The converging literatures on “good lives” and other developments in sexual offender treatment are compared with recovery from mental disorder and what is known about the particular needs and characteristics of sexual offenders with mental illness and severe personality disorder (PD).

A key outcome of this review is that many mentally disordered sexual offenders have similar needs to those in prison and the community but there are particular challenges posed by severe PD, paraphilias and the relatively rare individuals whose offending is functionally linked to psychotic symptoms.

Practical implications include the need for case formulation of complex needs related to mental disorder using direct and indirect measures of attitudes and interests. Treatment needs to be responsive to very different personality and mental health presentations as well as problems with offending and cognitive schemas. Direct functional links between mental health symptoms such as delusions and hallucinations are very rare in practice and are usually secondary to PD and sexual offending issues. In practice, treatment promoting recovery from mental disorder is highly compatible with the “good lives” approach to sexual offender treatment. Staff development, supervision and support are particularly important for staff treating mentally disordered sexual offenders.

It is argued that mentally disordered sexual offenders are an under-researched sub-group within the wider sexual offender population. This paper brings together the relatively limited literature on treatment with examples of recent treatment innovations, multi-modal assessment approaches and reviews of research on the needs of this relatively uncommon but highly risky group.
