Executive functioning profiles of adult and juvenile male sexual offenders: A systematic review

Evidence regarding biological correlates of sexual offending, which might enhance the understanding, research, and treatment of these offenders, is rather emerging or in the embryonic stage. In this study, our main objective is to identify specific executive functioning (EF) processes that are commonly impaired in sexual offenders, and to further determine whether these differ as a function of offender subtypes. A search is conducted in ProQuest, Criminal Justice Abstract, EBSCOhost, and Social Science Citation Index electronic journal databases for studies published spanning the period 1990–2015. Google Scholar and Google search engines were also searched and the reference lists of the retrieved papers were searched for additional papers. A total of 1303 papers were retained for consideration. After removing duplicates, and subjecting the retrieved papers to inclusion and exclusion criteria, 24 papers (19 published and 5 unpublished) were deemed appropriate for the review. While several EF processes have been investigated, the available evidence implicates deficits in cognitive flexibility and inhibition of interference as commonly reported among adult male sexual offenders. This finding may be due to the sensitivity of tests of cognitive flexibility (e.g. the Wisconsin Card Sorting Test) and inhibition of interference (e.g. the Stroop Test) to frontal lobe lesions, and also because these tests are among the most frequently administered EF tests as revealed by this study. Juvenile sexual offenders, however, exhibit no distinct EF profiles. The findings of the study, implications for treatment, and recommendations for future studies are succinctly discussed.     

The highs and lows of working with sexual offenders: A New Zealand perspective

Abstract

The positive effects on clinicians responsible for the treatment of sexual offenders are little understood. The few available studies have focused upon the negative sequelae of this work. The current study of clinicians working therapeutically with sexual offenders at a community-based organization aimed for a more balanced picture of the effects of sex offender treatment provision. Using qualitative methods, both negative and positive aspects of this work emerged within three main themes: taking an optimistic perspective, working for community outcomes and supportive agency culture. Although the study revealed many challenges for therapists, these were found to be counterbalanced against rewards, affording a high degree of personal and professional fulfilment from working within this field.     

Arbitrary decision making in the absence of evidence: an examination of factors related to treatment selection and recidivism for female sexual offenders

ABSTRACT

As criminal justice professionals are asked to assign risk levels and treat females who sexually offend, identifying risk factors for recidivism prediction and treatment targets is important. Although the majority of risk and treatment studies have focused on males, general female offender research and developing research with female sex offenders both provide some evidence for possible factors related to sexual offending behaviour in women. The purpose of this study was to explore what possible factors were related to treatment selection in a sample of 506 females serving prison sentences for a sexual offense, and, in turn, to examine which factors predicted non-sexual and sexual recidivism. Results demonstrated that exploratory variables were significantly related to treatment selection, as opposed to variables previously supported in research. Furthermore, living with a significant other for more than two years, and prior sexual offending arrests predicted sexual recidivism, while decreased age and treatment participation predicted non-sexual recidivism. These findings indicate that while similarities between male and female sexual offenders exist, females still demonstrate gender-specific risk factors.     

A modified Stroop task with sexual offenders: Replication of a study

Abstract

Cognitive–behavioural treatment of sexual offenders assumes that sexual offenders are motivated by deviant attitudes, perceptions and values. Although aspects of deviant schema can be assessed by questionnaires, self-report measures are limited by the respondent's willingness to be forthright and by the fact that, typically, these cognitive processes occur quickly, revealing signs of automaticity. Recent research by Smith and Waterman has suggested that the deviant schema of sexual offenders could be assessed using a version of the Stroop colour-naming task. Long latency periods to sexual colour words imply a longer information-processing route and evidence of pre-established (deviant) sexual cognitive schema. Stroop techniques may offer the advantage of eliminating limitations that arise when using self-report techniques, such as fakeability and social desirability concerns. The current study replicates and extends Smith and Waterman's results using samples of sexual offenders, non-sexual violent offenders and non-violent offenders. The cumulative results of the two studies suggests that Stroop techniques have promise, but that further work is required before measures are available that have sufficient reliability and validity to be used in applied contexts.     

Referrers' views of structured professional judgement risk assessment of sexual offenders: A qualitative study

Abstract

The Risk for Sexual Violence Protocol is a structured professional judgement (SPJ) tool that aids risk assessment of sexual violence. It is widely used internationally. The aim of this study was to explore the clinical practice of SPJ risk assessment and risk management through qualitative analysis of the accounts of users of these assessments. Questionnaires and semi-structured interviews were conducted with a sample of 31 criminal justice professionals in southeast Scotland. The participants' accounts were explored using the framework method. Five themes emerged from this analysis: informing risk management; confirming what was known and giving weight; understanding personality; treatment; and the usefulness and limitations of risk assessment. The participants reported that the assessments were influential with respect to risk management. The study revealed some important implications for service development. The authors suggest possible future use of the framework method in research investigating the risk assessment of sexual violence.
