Is the Risk Matrix 2000 applicable to intellectually disabled sex offenders?

Abstract Background Sex offender risk assessment is complex, especially when this concerns intellectually disabled sex offenders (IDSOs). This subgroup of sex offenders require specific attention in relation to risk assessment, yet tools designed for non-IDSOs continue to be applied to them. Method This review examines the Risk Matrix 2000, a static risk assessment tool that is designed to assess risk of sexual and violent recidivism. Its validity, reliability and practical utility for sex offenders with intellectual disabilities are explored. Results Appraisal of this tool indicates that although empirical support exists for its use with sex offenders without intellectual disability, the Risk Matrix 2000 is not established as reliable or valid for use with IDSOs. Although less extensively empirically examined than the Risk Matrix 2000, the ARMIDILO-S, which incorporates protective factors as well as risk factors, shows superior predictive validity to the Risk Matrix 2000 with IDSOs and its use may therefore be more ethically defensible. Specific testing of actuarial (and other types) of tools is required on IDSOs. Conclusions Further empirical support is needed to support the use of the Risk Matrix 2000 with IDSOs, and other risk assessment tools that are designed specifically for this subgroup of sex offenders may be more appropriate to use. The Risk Matrix 2000 and its resulting risk groups should not be relied upon for IDSOs and its continued use on this subgroup is questionable.

Controversies in assessing risk and deviancy in sex offenders with intellectual disabilities

While the literature on the assessment, treatment and management of non-intellectual disabled sex offenders is well established, it is only in recent years that researchers and clinicians have focused on sex offenders with intellectual disability (ID). This article focuses on two areas: the assessment of risk and recidivism, and the assessment of sexual deviancy in sex offenders with ID. The first part of this article reviews the literature on the assessment of sexual offence recidivism risk for sex offenders with ID. Static and dynamic risk factors associated with sexual recidivism risk in sex offenders with ID are identified and the use of actuarial risk assessment scales and structured risk assessment systems with this client group are considered. The second part of this article discusses difficulties associated with the assessment of sexual deviancy in sex offenders with ID. An alternative approach to assessing deviancy is considered where deviant behaviour is compared against a four-group continuum of normal to deviant sexual behaviour in terms of developmental and chronological levels. From the literature a number of suggestions are made regarding the assessment of risk and sexual deviancy with this client group.

Actuarial risk assessment and recidivism in a sample of UK intellectually disabled sexual offenders

This study examines the effectiveness of three risk assessment instruments: Static-99, Risk Matrix 2000 (RM2000) and the Rapid Risk of Sex Offender Recidivism (RRASOR), in predicting sexual recidivism among 27 intellectually disabled sex offenders. The overall sexual offence reconviction rate was 30%, while non-recidivists remained offence-free over 76 months of follow-up. Static-99 presented as performing as well as guided clinical judgements in mainstream population studies [area under the curve (AUC)=0.64] exceeding the performance of RM2000 (AUC=0.58) in predicting sexual recidivism. However, the results were not statistically significant. In contrast to previous findings, the RRASOR presented the worst level of prediction (AUC=0.42). These results highlight the need to investigate further with larger sample sizes and in conjunction with more dynamic measures of risk. Proposed relevant factors are discussed in detail.

Thresholds and the Abstinence Violation Effect

The idea that sexual offenses occur as the culmination of a chain of actions on the part of offenders is central to contemporary cognitive behavioral models of relapse prevention. However, quantitative tests of this idea have remained rare. This article presents a mathematical model of the offense chain that allows a quantitative hypothesis test and tests the model using archival records of the daily behaviors of 7 developmentally disabled sex offenders. The results lend statistical support to models of the offense chain and allow consideration of the implications of the dynamics of offender behaviors for treatment

Identifying the developmentally disabled sex offenders

The identification, assessment and treatment of the mentally retarded sex offender presents a dilemma for not only professional evaluators and departments of developmental disabilities, but also for law enforcement agencies, criminal justice systems and, in some cases, the correctional system. The paucity of information on the mentally retarded sex offender leads many professionals to offer patchwork types of treatments and treatment planning which does nothing to alleviate the problem. This article will provide professionals with a framework which can be modified and used to justify treatment. The presentation seeks to integrate information gathering and clinical knowledge into a comprehensive treatment plan that takes into account specific interventions as well as accountability for the rights of the mentally retarded.
