Current methods at present allow, in most cases, only for an estimate of the likelihood of both future sexual and nonsexual offending over a specific timeframe. An independent validation of the Violence Risk Scale: While consideration of the above factors has added to the ability to accurately assess sex offender risk, the literature also has identified factors that do not contribute to the accurate assessment of risk. Second, focusing on risk alone can lead to over-prediction of violence risk. A Journal of Research and Treatment, 24 3 , — 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. A long-term follow-up. 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. Ontario, Canada: Using logistic regression modeling to predict sexual recidivism: Sex Offenses and Offenders: A Journal of Research and Treatment. Fact Sheets Risk Assessment Risk assessment is an important process for many areas relating to sex offenders. These rules involved starting with the Static risk categories, and adjusting the overall rating based on the Stable scores. The impact of polygraphy on admissions of victims and offenses in adult sexual offenders. The polygraph has increasingly been utilized to verify information provided by sex offenders regarding the details of the alleged offense, conduct, and past sexual history. Canadian Psychology, 50, — Absolute recidivism rates predicted by StaticR and StaticR sex offender risk assessment tools vary across samples. An assessment of long-term risk of recidivism by adult sex offenders: Analyzing the jurisdictional variation in recidivism rates is beyond the scope of the current report, but readers should be aware that some of the variation in outcome was associated with jurisdictional differences that could not be accounted for by the variables measured in this study. Parent, G. Levenson, personal communication, May 23, 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. Grove, W. Sexual offender assessment



User Report Assessment of sexual offender risk and need in a treatment context. The first revision retains all the original items but provides new rules for combining the static and stable items into an overall evaluation of case priority. Analyzing the jurisdictional variation in recidivism rates is beyond the scope of the current report, but readers should be aware that some of the variation in outcome was associated with jurisdictional differences that could not be accounted for by the variables measured in this study. Using logistic regression modeling to predict sexual recidivism: Across a variety of situations, trained professionals can now offer informed risk assessments of the likelihood of future sexual offending for a variety of sex offenders. A Reasoned Approach: Doren's recommendations for communicating the results of sex offender risk assessment, especially in cases involving civil commitment, include the following: The ability to detect meaningful changes in risk, especially for high-risk offenders, is particularly important Hanson, ; Olver et al. While it stands to reason that clinicians would want to consider dynamic factors when assessing risk, doing so via clinical adjustment of actuarial instruments has not been found to be effective. Seven of the 16 items showed significant linear relationships to all outcomes: Are there really differences between the normative groups? As a result, the assessment of risk by necessity involves the combination of a number of risk factors in a meaningful manner. Rapists had unrelated victims age 14 or older, or any victims age 18 or older.

These are dynamic that is, changeable risk factors that can serve as targets for intervention efforts. The inverse relationship between age and criminal offending — as age increases, offending decreases — is one of the more robust findings within criminology. Five types of recidivism were recorded. Analyzing the jurisdictional variation in recidivism rates is beyond the scope of the current report, but readers should be aware that some of the variation in outcome was associated with jurisdictional differences that could not be accounted for by the variables measured in this study.

Canadian Psychology, 50, — How should risk assessments for sex offenders be conducted? Wollert, R.



































Sexual offender assessment



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. To date, no single characteristic that is, "risk factor" has been found in isolation to be a robust predictor of recidivism. Unstructured professional judgment and actuarial instruments for assessing violent recidivism risk were less accurate in assessing the likelihood of sexual recidivism. Less Is More: The clinical-statistical controversy. Criminal Justice and Behavior, 37 5 , — Improving the predictive accuracy of Static and Static with older 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. In practice, the static assessment took approximately 30 minutes to complete. J Am Acad Psychiatry Law. A Journal of Research and Treatment, 24 3 , — Swinburne Romine, R. Maruna, S. Helmus, L. Viewing time as a measure of sexual interest among child molesters and normal heterosexual men.

Both volume and circumferential plethysmography should be administered in a controlled environment that minimizes exposure to external stimuli that might interfere with test results a dark, sound attenuated booth is ideal. References Ackerman, A. This paves the way for inclusion of other factors and characteristics related to risk, such as dynamic factors, treatment effects, inclusion of strengths and protective factors, and factors predictive of desistence. Incorporating change information into sexual offender risk assessments using the Violence Risk Scale—Sexual Offender Version. The assessment of risk of recidivism by adult sex offenders. Screening tests for pedophiles. In the last ten years, the relative accuracy of risk assessments has improved substantially, particularly as they pertain to sexual re-offending.

University of Toronto, Centre of Criminology. In some cases, the police provided information about new offences that had yet to appear on other records. A Theoretical Analysis and a Review of the Evidence. Consequently, the offenders from Quebec all signed consent forms allowing their assessment data to be used for this study. The survival end date was the earliest of the following events: Sex offender risk assessment, while similar in many ways to the assessment of other latent constructs psychological concepts within psychology and mental health, differs in at least one significant aspect. Journal of Consulting and Clinical Psychology, 73, — 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.

American Journal of Sociology, 89, — Current methods at present allow, in most cases, only for an estimate of the likelihood of both future sexual and nonsexual offending over a specific timeframe. Discussions of the relative merits of this approach can be found in Wollert and colleagues, ; Hanson and Morton-Bourgon, ; Doren, ; and McGrath, Cumming and Lasher, User Report The characteristics of persistent sex offenders: Penile plethysmography test results are often used to characterize patterns of deviant sexual arousal, develop treatment plans, and monitor the effectiveness of treatment. 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. It is nonetheless important to provide ongoing training and monitoring of evaluators to ensure that risk-assessment procedures and instruments are always used appropriately and with integrity. The evaluator 1 reviews case material and applies personal experience to arrive at a risk estimate, without relying on a specific list of risk factors or underlying theory to prioritize or weight any of the information used. Despite its limitations, penile plethysmography is generally considered the most accurate measure of sexual arousal. Evaluators can also make mistakes when communicating the results of risk assessments. 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. Advances in both psychiatry and neuroimaging techniques allow for the exact imaging of neuroanatomical correlates of sexual arousal and represent ongoing areas of future research. Increasingly greater attention will be paid to the conceptual nature of risk factors and the interrelationships between them. Victim, Incident, and Offender Characteristics. Even highly correlated measures can add incrementally to predicting recidivism among sex offenders. Many studies have examined the effects of clinical adjustments to the results of actuarial instruments, finding that "overrides" — a clinician's consideration of factors outside the actuarial scheme i. Advancing sexual offender risk assessment: Sexual offender assessment



As a subject is exposed to sexual stimuli, alterations in voltage through the strain gauge are monitored and converted to penile diameter size based upon on the pre-calibrated settings. This would suggest that practically all of the current well-validated risk factors provide some degree of unique and predictively useful information. Less Is More: Jackson, R. Washington, DC: The evaluator 1 reviews case material and applies personal experience to arrive at a risk estimate, without relying on a specific list of risk factors or underlying theory to prioritize or weight any of the information used. Crime and Justice, While consideration of the above factors has added to the ability to accurately assess sex offender risk, the literature also has identified factors that do not contribute to the accurate assessment of risk. Assessing sex offender risk and evaluating therapeutic change. Protective strengths, risk, and recidivism in a sample of known sexual offenders. Seligman, M. A number of reliable, valid approaches for assessing sex offender risk are now available. Given that the original Stable has already been fully implemented in some jurisdictions, subsequent analyses present findings for both the original Stable and two revisions. File review conducted for the purpose of the reliability training suggested that the selection of cases was not always consecutive. One thing worth mentioning is that the use of psychophysiological tests to accurately predict recidivism for any given individual has not been demonstrated in controlled studies. The typical venues for sex offender risk assessment include — The purposes of risk assessment span the spectrum of the adjudication process. In effect, this entails identifying treatment targets and assessing the impact of treatment on risk and other factors, such as institutional misconduct or the amount of time that has elapsed without a new conviction K. As Doren , p.

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, , Given that criminal history records were the major source of recidivism information, the vast majority of recidivism events were linked to an officially recorded charge or conviction. Neither of these instruments, however, has the research backing of the more established instruments of static risk, such as the StaticR and Static R. An independent validation of the Violence Risk Scale: 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. RA is concerned with predicting the degree of possibility of a sexual re-offense for someone with a known history of sex offending. A multi-site study of Static Accurately assessing risk is critical in making decisions related to sex offenders such as: Who are the people in your neighborhood? The ideal categorical risk levels would not be tied to a particular risk instrument but rather would apply across the range of risk measures. Toronto, ON: Seligman, M. Simply put, people tend to overestimate the likelihood of low-probability events and underestimate the likelihood of high-probability events. 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. 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. In addition to obtaining an individual's subjective self-report of sexual arousal patterns, it is important to incorporate objective measures of an individual's sexual preferences. Currently, there a number of ways of offering meaningful risk assessments of future sex offense recidivism. The following represent emerging trends and future directions in this field. Assessment , 23 1 , 96— Sex offender Version. A Journal of Research and Treatment, 19, — A Journal of Research and Treatment, 27 4 , — The current behaviour was to be interpreted in the context of the overall risk level previously determined by the static and stable variables. Increasingly greater attention will be paid to the conceptual nature of risk factors and the interrelationships between them. Nipissing University. Criminal Justice and Behavior, 39 9 , — In a study that included adult male sex offenders under correctional supervision and enrolled in sexual offender treatment, study participants were assessed using a number of actuarial measures as well as the item SOTIPS. Sex offender treatment outcome, actuarial risk, and the aging sex offender in Canadian corrections: Specific measures have been found helpful in the assessment of dynamic risk factors e.

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, Some proposals on the nature of psychologically meaningful risk factors. Criminal Justice Policy Review, 21, 31— The training primarily involved descriptions of the scoring criteria and structured exercises both oral and written. Given the lack of a single best risk-assessment instrument, evaluators will continue to have to rely on their professional judgment to select and employ the best risk-assessment approach for the circumstances and setting. Phenix, personal communication, May 10, , each of the structured approaches has its merits as well as its supporters and detractors Doren, ; A. The attitude section assessed: The Adam Walsh Act: The evaluator begins with a finite list of factors identified in the professional literature as being related to risk. 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. Crim Justice Behav. Additionally, there are ethical concerns associated with the intrusiveness of using plethysmography in adolescents and having subjects view pornographic stimuli especially of children.

In addition to obtaining an individual's subjective self-report of sexual arousal patterns, it is important to incorporate objective measures of an individual's sexual preferences.
