Risk assessment for sex offenders

The intraclass correlation ICC for Static was. A Journal of Research and Treatment, p. Levenson, J. Olympia, WA: In introduction. An Assessment of Clinical Techniques in to usher in a truly scientific approach to violence risk assessment. Epperson, D. Age and the explanation of crime. As noted previously, the Static and Static have been revised to incorporate the impact of aging on risk, resulting in the inclusion of new age weights and the publication of the StaticR and StaticR Helmus et al. Doren, D. Babchishin, K. As a result, assessors must be aware of the underlying constructs represented by the risk assessment s they employ. The following types of risk assessment approaches were included in the analysis: Assessment of dynamic risk factors: Clinical Psychology Review, 33 2 , — The Dynamic Supervision Project. Unstructured professional judgment and actuarial instruments for assessing violent recidivism risk were less accurate in assessing the likelihood of sexual recidivism. While qualitative descriptions in general and these particular nominal descriptors are usually preferred over numerical formats for communicating risk, the use of qualitative labels alone has certain limitations. Empirical research has yet to identify a single "best" risk assessment instrument. There are various numerical formats commonly used to convey absolute risk, such as frequencies e. The development and initial testing of the AIM2 framework to assess risk and strengths in young people who sexually offend. While significant advances have been made regarding the reliability and predictive validity of instruments, a number of limitations remain. Approximately one third of the officers completed one of three different exercises. Risk assessment for sex offenders



The minimum information required was a structured interview with the offender and a file review of sufficient depth to score the static information requested above Static scores, victim information, demographics. One of the primary challenges for the field in the future will be to identify more comprehensively the risk factors both static and dynamic that are related to sexual offending. Violent Offenders: These rules involved starting with the Static risk categories, and adjusting the overall rating based on the Stable scores. Officers were not directed to compute total scores, but to consider the current risk factors in the context of the offender's pre-determined risk level based on the static and stable factors. RA is concerned with predicting the degree of possibility of a sexual re-offense for someone with a known history of sex offending. Stable variables The association between the 16 stable items and recidivism was examined using correlation coefficients, frequency tables, and ROC analyses. Risk Assessment. The training primarily involved descriptions of the scoring criteria and structured exercises both oral and written. Crime and Justice, For the few cases that did not appear on any official record, the follow-up end date was set one month after the last assessment information was received. Klima, T. Who are the people in your neighborhood? The assessment of risk of recidivism by adult sex offenders. Risk assessment RA is the process of identifying the probability or likelihood of future dangerousness or harm, such as a sexual offense. Training and monitoring of evaluators is needed to ensure that risk assessment procedures and instruments are used appropriately and with integrity. Recidivism Information concerning new offences was gathered through reviews of state, provincial, and national Canadian criminal history records, as well as from supervising officers and local police jurisdictions. For more detailed information about risk assessment in California, see www.

Nipissing University. Therefore, even when different scales share one or more category descriptors, they do not describe the same thing. The Dynamic Supervision Project. An examination of the interrater reliability between practitioners and researchers on the Static Predictive validity of the LSI-R among a sample of adult male sex assaulters. Law and Public Policy, Clinical Practice. In fact, there are certain populations for whom there is no validated risk-assessment instrument e. Parent, G. Incorporating dynamic risk factors e. Psychology, Public Policy, and Law, 2, — Frequently, decision-makers want the risk-assessment process to provide them with information on the likelihood of recidivism, the potential consequences associated with recidivism and what might be done to mitigate the assessed risk Hanson, Storey, J. Nominal categories should be explicitly defined so as to limit the degree to which readers define for themselves the meaning of the specific nominal descriptors. Additional research concerning the use of dynamic risk factors is clearly needed, is further work to explore the factors that lead to desistence from sexual offending Griffin et al. Recidivism Information concerning new offences was gathered through reviews of state, provincial, and national Canadian criminal history records, as well as from supervising officers and local police jurisdictions. The review cases were selected randomly from the settings providing the largest number of complete cases static, stable and acute data submitted , as well as additional locations that fit into the travel schedule of the expert raters Footnote 1. Cale, J. Advancing sexual offender risk assessment: Implications of static field reliability findings for score use and reporting. A Journal of Research and Treatment, 24 4 , — In Taxman, F. Assessing risk for sexual recidivism: Results of a study involving 83 contact sexual offenders show good interrater reliability and negative correlations between the SAPROF and two actuarial tools. Turner, D. For the prediction of sexual recidivism, actuarial instruments designed for assessing the risk of sexual recidivism had the greatest predictive accuracy, followed by mechanical approaches designed for assessing the risk of sexual recidivism and actuarial instruments designed for assessing the risk of general recidivism.

The agreement was high between the original ratings and the consensus ratings developed through file reviews. Nafekh, M. With this and the limitations of using only one risk assessment instrument particularly in especially high-stakes situations such as civil commitment evaluations in mind, clinicians have considered the potential benefits of using more than one instrument during the assessment process Doren, ; Hanson, , Figure 1. It is often undertaken for dispositional purposes to help determine, for example, an appropriate sentence or custody level or the conditions of community supervision. Seven of the 16 items showed significant linear relationships to all outcomes: Protective strengths, risk, and recidivism in a sample of known sexual offenders. In a manner similar to the standardized risk assessment levels proposed by CSG's Justice Center, the new categories for the Static measures have been designed to be applied across a wide range of sex offender risk-assessment measures. An exploration of protective factors supporting desistance from sexual offending. Increasingly greater attention will be paid to the conceptual nature of risk factors and the interrelationships between them. A Psychometric Examination. From this perspective the traditional perspective of psychological assessment , the factors that successfully predict recidivism both static and dynamic do so because they serve as indicators for the latent traits or constructs directly related to the risk of criminal behavior. Eher, R. The accuracy of structured professional judgment methods fell in between these two methods. Grove, W. Griffin, H. In all cases, the data remained the property of the specific jurisdictions, and the researchers at Public Safety Canada were in the role of data managers. The minimum information required was a structured interview with the offender and a file review of sufficient depth to score the static information requested above Static scores, victim information, demographics. The evaluator begins with the administration of an existing actuarial instrument and then employs a finite list of considerations that can be used to raise or lower the assessed level of risk. International Journal of Law and Psychiatry, 34 3 , —

Even highly correlated measures can add incrementally to predicting recidivism among sex offenders. Smallbone, S. The requested data collection protocol involved submitting static information including Static within the first month of supervision. The manual instructed evaluators to estimate the offender's typical or baseline level of functioning during the following 6 to 12 months based on all available information. Risk assessments in child sexual abusers working with children. Improving risk assessments for sex offenders: It may very well be that the reason that so many of the actuarial static risk assessments possess roughly equivalent predictive ability is because they have reached a limit asymptotic in terms of the amount of variability in risk than can be predicted with reference to static factors alone. Olver and colleagues describe their application of logistic regression to combine risk and change information into clinically meaningful post-treatment risk assessments Olver et al. First, estimated base rates for a particular follow-up period can be used to establish a benchmark for the likelihood of general classes of sex offenders such as rapists or child molesters. Quesada, S. One size doesn't fit all. Advancing sexual offender risk assessment: Olver, M. Sex offenders of various types are a very heterogeneous group. The StaticR is based on static unchanging risk factors which predict the potential for sexual re-offending, such as age at release from custody on the sex offense, number of certain types of prior convictions, and victim characteristics. Notwithstanding pseudoscientific methods such as phrenology which claimed to gauge behavior propensities based on measurements of the skull , risk assessment for many decades has primarily involved individual mental health professionals applying their accumulated experience and clinical acumen to produce a clinical judgment of the degree of risk posed by a particular individual. The Violence Risk Scale: Given that some of the sexual offences were not violent e. Examining the re-entry court concept from a strengths-based perspective. A Journal of Research and Treatment, 24 4 , — Implications of static field reliability findings for score use and reporting. As noted above, there is currently no single "best" risk assessment for all offenders in all situations. Storey, J. Vancouver, BC: To that end, Hanson has provided the following set of qualities to guide the future of sex offender risk assessment: A Meta-Analysis. An examination of the interrater reliability between practitioners and researchers on the Static One of the primary challenges for the field in the future will be to identify more comprehensively the risk factors both static and dynamic that are related to sexual offending. Risk assessment for sex offenders



Langevin, R. The need for tailored rather than uniform interventions, and the need to match sex offender treatment and management efforts to the risk levels and criminogenic needs of sex offenders, were acknowledged by the experts— both researchers and practitioners— who participated in the SOMAPI forum. A prediction is limited by the length of time that identified sex offenders can and have been followed for study. The Static family of measures are by far the most often used sex offender risk assessments in the United States and Canada Storey et al. Recent studies of the structure of risk assessment instruments have also identified potential additional factors assessed by these measures Brouillette-Alarie et al. Criminal recidivism was considered to have occurred if the agency reporting the information believed that the offence occurred. The use of third-generation risk assessment instruments that incorporate both static and dynamic risk factors is becoming more prevalent. Journal of Consulting and Clinical Psychology, 73, — The construct being assessed — the commission of a new sexual offense — is unobservable and is likely never to be observed by the assessor. The emergent emphasis within risk assessment on more positive and healthy aspects of individuals is also reflected in the literature concerning desistence from crime. Neither of these instruments, however, has the research backing of the more established instruments of static risk, such as the StaticR and Static R. The first section, significant social influences, identified the people in the offender's life who were not paid to be with him or her, and then computed a section score based on the number of positive and negative social influences. A great deal of empirical support has demonstrated the utility of actuarial risk assessments, and the best of these measures are all approximately equal in their ability to assess risk for reoffense. University of Minnesota. Static contains 10 items based on criminal history, victim characteristics gender, relationship to offender and relationship history. A multi-site study of Static Implications of static field reliability findings for score use and reporting.

Unstructured professional judgment and actuarial instruments for assessing violent recidivism risk were less accurate in assessing the likelihood of sexual recidivism. An offender who is offense-free for at least 10 years in the community after release may not be eligible at that point for scoring on the StaticR, unless he commits another sex offense or other serious offense. Thornton, D. While significant advances have been made regarding the reliability and predictive validity of instruments, a number of limitations remain. While numerical estimates provide more information and are potentially less ambiguous than qualitative descriptors alone, they too have limitations. Do measures of lifetime history of substance abuse add to the prediction of recidivism over actuarial risk assessment instruments? Allow all relevant factors to be considered. The ideal categorical risk levels would not be tied to a particular risk instrument but rather would apply across the range of risk measures. The contribution of Paul E. A Journal of Research and Treatment, 25 5 , — Based on current knowledge, using science-based, actuarial methods to assess sex offender risk is advisable. Risk-needs assessment and treatment. Results The overall recidivism rates for the male offenders in the sample were as follows: When combined using a statistical procedure known as logistic regression, both the SOTIPS and StaticR consistently performed better than either instrument did in isolation. From the standpoint of construct validity, the factors measured in assessment are indicators for unobservable referred to as latent traits or constructs. Adjusted actuarial approach: Some jurisdictions required officers to attend the training, and other jurisdictions adopted all or some of the measures as standard practice; however, the decision to submit data to the research project was at the initiative of the individual officers. Second, research has identified risk factors that can be used to identify those sex offenders at a higher risk to re-offend. There are three generations of risk assessment methods: In this context, risk assessment typically involves arriving at an estimate of the likelihood that an offender will recidivate that is, revert to illegal behavior after the individual experiences legal consequences or intervention for a prior criminal act. Most of the training sessions were conducted by the principal investigators, although other trainers were used in some jurisdictions. Recently, significant focus has been directed toward a more contextual understanding and assessment of risk, conceptualizing risk as but one aspect of a larger and more holistic understanding of the individual. One way to mitigate the problems associated with the exclusive use of nominal categories is to also provide numerical indicators of risk, such as a recidivism rate probability, a percentile rank Hanson et al. Revised age weights. Back To Top Review of Research Sex offender risk assessments are most often employed in applied forensic settings for purposes of decision-making Doren,

Risk assessment for sex offenders



The following nominal categories were proposed: Langevin, R. The accuracy of recidivism risk assessments for sex offenders: Violent Offenders: Once a recidivism event was identified, we then obtained the date on which the offence occurred, and a brief description of the offence behaviour in order to classify it into one of five categories see below. Consequently, the last known recidivism event was in February, — the date of our last follow-up with a police jurisdiction. Criminal lifestyle characteristics e. Looman, J. There also exists to a certain degree of agreement as to the characteristics of the offenders that make up either end of the risk continuum. It is reasonable to assume that for the one item in which all the officers disagreed with the answer key, the answer key was incorrect. Mann, R. Consequently, these reliability reviews should be considered a test of the extent to which the officers understood the coding rules rather than a test of the concordance between fully independent assessments. Therefore, it is critically important to establish a clear understanding of exactly what risk is being assessed and to frame expectations accordingly. Specific measures have been found helpful in the assessment of dynamic risk factors e. Hanson and Bourgon in press describe an ongoing process by which the Council of State Governments CSG Justice Center is working to define risk levels for the prediction of general criminality. Tabachnick, J. The reasons for scoring only some new cases are unknown, but appeared to be related to the degree of local administrative support for the project and the competing time demands placed on the officers. Accurately assessing risk is critical in making decisions related to sex offenders such as:

StaticR Risk Scores The StaticR score is used to predict risk of sexual reoffense, based on the offender's score category. An examination of the interrater reliability between practitioners and researchers on the Static Journal of Interpersonal Violence, 26 4 , — In addition to the Static items, the static questionnaire included basic demographic information for the offender as well as the ages and pre-existing relationships for all known victims of sexual offences. Given that some of the sexual offences were not violent e. The first one, the StaticR , is used to assess male sex offenders presentencing and prior to release from prison. A Journal of Research and Treaetment, 27 1 , 51— Rigorous former dating has demonstrated that enjoyable levels of sexual accuracy have been deleted with physically actuarial risk assessment performs, approaches healing instant professional guise and the rage combination of others from marital risk schemes.
