    A lthough the desire to predict the risk of future violence posed by individuals is likely centuries old, risk assessment efforts until recently have been relatively unsuccessful in terms of their predictive accuracy.

    Notwithstanding pseudoscientific methods such as phrenology which claimed to gauge behavior propensities based on measurements of the skullrisk 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 asswssments a particular individual.

    In the three decades since the publication of Monahan's book, the relative accuracy of violence risk assessments has increased substantially. Risk ability to accurately assess the likelihood of future violent acts asaessments and future criminal behavior more generally — is important to clinicians, policymakers and the public alike.

    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 qssessments for a prior criminal act. Risk assessment serves many purposes throughout the adjudication offenders.

    It is often undertaken for dispositional purposes to help determine, for example, an appropriate sentence or custody level or the conditions of community supervision. In these situations, decisions are often offejders, at least assessments part, on the assessed likelihood of recidivism, with resources being allocated accordingly to promote community safety Kingston et al.

    Research has suggested that offenders convicted of sexual offenses have received more attention from policymakers than awsessments other category of offenders over the past 25 fr Ackerman et al. Indeed, estimates of risk for sex offenders fro used in various community corrections, institutional corrections and civil commitment decision-making contexts.

    Arguing from a policy standpoint, Tabachnick and Klein have stated offfenders the results of actuarial risk assessments in particular should inform decision-making at all levels regarding ofenders supervision of adult sexual offenders in order to prevent recidivism. Risk the role played by risk assessment in high-stakes assessmente such as zex involving potential civil commitment for those designated as sexually violent predators, as well as the possibility of lifetime community supervision, reliance on methods and procedures possessing a strong scientific evidence base is especially critical.

    While much progress has been made regarding the ability of professionals in the field to accurately estimate the likelihood of future sexual reoffense, no one is presently able to estimate either the offenders offencers the severity of such future criminal conduct J. Levenson, personal communication, May 23, Therefore, it is critically important to establish a clear understanding of exactly what risk is being assessed and to frame expectations accordingly.

    Current methods at present allow, in most cases, only for an estimate of the likelihood of both future sexual and nonsexual offending sex a specific timeframe.

    The accuracy of these estimates depends in part on the degree to which the individual offender being assessed matches a known group of sex offenders knows as the normative sample or norm group and the degree to which the factors included in the risk assessment accurately assessments the known universe of relevant risk factors.

    Sex offender risk assessments are most often employed in applied forensic settings for purposes of decision-making Doren, The typical venues for sex offender risk riwk include —. Dor 1.

    Phenix, personal communication, May 10,each assessmfnts the structured approaches has its merits as well as its supporters and detractors Doren, ; A. Phenix, personal communication, May 10, Criminologist James Sex has identified risk generations of risk assessment methods: unstructured professional opinion corresponding to Hanson's [] unstructured clinical judgmentfor methods risk static predictors corresponding to Hanson's actuarial approach and methods that include both static and dynamic factors referred to by Bonta as criminogenic needs.

    By including offnders risk factors in the assessment process, third-generation risk assessments can be used to both guide and evaluate the impact of intervention efforts. Recent studies have in fact demonstrated that the inclusion of dynamic risk factors can contribute incrementally to the ability of static relatively unchangeable risk factors to accurately predict risk gor sexual reoffense Eher assessments al.

    There are three generations risk risk assessment methods: unstructured professional opinion, actuarial methods assessments static predictors and methods that include both static and dynamic factors. For accurate risk assessment to occur, the factors associated with the type of risk being assessed must be known. Knowledge about the risk factors associated with recidivism typically is generated through research in offendres the recidivism rate for offenders with a particular characteristic is compared to the recidivism rate for offenders without sex characteristic, or for offenders possessing other characteristics Hanson, To date, no single offenders that is, "risk factor" has been found in isolation to be a robust predictor of recidivism.

    As a result, the assessment of risk by necessity involves the combination of a number of risk factors in a meaningful manner.

    The strongest predictors assessments sexual recidivism are factors related to sexual criminality, such as a demonstrated sexual interest in children, a history of prior sexual offenses, the age of onset of sexual offending behavior and having committed a variety of sexual offenses. Criminal lifestyle characteristics e. More recent analyses of the specific factor structure of actuarial risk assessments have reinforced the stability of assessments two factors — sexual and general criminality Babchishin et al.

    Recent studies of the structure of risk assessment instruments have also identified potential additional factors assessed by irsk measures Brouillette-Alarie et al. 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.

    These developments are part of a larger move away from a singular focus on deficits and psychopathology toward a view that incorporates consideration of assets and strengths. A number of researchers have assessed the contribution of strengths, assets and assessments factors to the prediction of sex offender risk Miller, ; Turner et al. Available at present are at least four risk assessment measures for use with adults that include assessment of assets, strengths or protective factors Miller, Results of a study involving 83 contact sexual offenders show good interrater reliability and negative correlations between the SAPROF and two actuarial tools.

    Another aspect of dynamic assessment that has gained recent attention concerns the tor of change offendfrs with participation in treatment. In a study that included offenders male sex offenders under correctional supervision and enrolled in sexual offenders treatment, study participants were assessed using a number of actuarial measures as well as the item SOTIPS.

    One and three years following assessment, both the StaticR and the SOTIPS demonstrated offenders ability to rank order risk for assessments, violent and any criminal recidivism and return to prison. When combined using a statistical procedure known as logistic regression, both the SOTIPS and StaticR consistently performed better than either instrument did in isolation. Furthermore, study participants whose Offeners scores suggested that they made progress in treatment demonstrated offneders rates of recidivism than participants who didn't demonstrate a treatment effect.

    The emergent emphasis assesments risk assessment on sexx positive and healthy aspects of individuals is also reflected in the literature concerning desistence from crime. De Vries Robbe assessments colleagues reviewed the available literature regarding protective factors and desistance from sex offending, and concluded there are three compelling reasons to include the assessment of strengths in offenedrs offender risk assessment.

    First, to do so may assessments the predictive validity of current risk assessment instruments. Second, focusing on risk alone can lead to over-prediction of violence risk. And third, assessments that focus only on deficits and pathology lead to the stigmatization of those assessed de Vries Robbe et al. Rather than simply viewing the absence of a need as a strength, the desistence literature identifies certain characteristics as assets for their own right, such as positive social relationships and the presence of healthy coping mechanisms.

    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 ffor of risk. Sex offender risk assessment, while similar in many ways to the offenderd of other latent constructs psychological concepts within psychology and mental health, differs in at least one significant aspect.

    The construct lffenders assessed — the commission of a new sexual offense — is unobservable and is likely never to risk observed by the assessor. Sex offender risk assessment entails a process of sex the likelihood of a future event based entirely on secondary, indicator variables Hanson, While actuarial risk assessment tools adsessments meet standard criteria for psychological measures e.

    It is important to keep in mind that for purposes of risk riskk, the utility of a risk factor depends on its empirical relationship to the outcome being predicted Helmus et al. The base rate is equal to the proportion of a group that shares a specific cor. For purposes of sex sex risk assessment, the relevant base rate is the proportion of convicted sex offenders who commit a subsequent sexual offense, either over a specified timeframe or over the course of their lifetime.

    These studies found the five -year recidivism rate to be approximately 13 percent. However, it is for to remember that this offenders is an underestimate, given that not all recidivist behavior is detected. The accurate assessment of risk involves fr an understanding of all available, relevant factors associated with the known criterion or outcome behavior.

    While research findings are quite consistent regarding the historical, relatively unchangeable factors referred to as "static" risk factors e. Neither of these instruments, however, has the research backing of the more established instruments of static risk, such as the StaticR and Static R.

    Offenderrs instruments have the potential added benefit of providing targets for intervention. The use of third-generation risk assessment instruments that incorporate both static and dynamic risk factors is becoming more prevalent.

    These instruments have the potential added benefit of providing targets for treatment. A variety of sex offender risk assessment tools possess acceptable, empirically supported psychometric ffor Doren,; Hanson, ; Hanson et al. While a complete review and analysis of these instruments is beyond the scope of this awsessments, a meta-analysis conducted by Hanson and Morton-Bourgon provides important insights concerning the relative accuracy of different approaches.

    Their analysis consisted of findings drawn from distinct samples with a total sample of 45, sex offenders in 16 countries. The following types of risk assessment approaches were included in risk analysis: empirical actuarial, mechanical using factors chosen primarily on the basis of theory or literature reviewsadjusted actuarial, structured professional judgment and unstructured professional judgment.

    Hanson and Morton-Bourgon concluded that empirically sxe actuarial approaches were more accurate than unstructured professional judgment in assessing risk of all outcomes — sexual, violent and any recidivism. The sex of structured professional judgment methods fell in between these two methods.

    For the prediction of sexual recidivism, actuarial instruments designed for assessing the risk of sexual recidivism offennders the greatest predictive accuracy, followed by mechanical approaches designed for offenders the risk of sexual recidivism and actuarial instruments designed for assessing the risk of general recidivism.

    Unstructured professional judgment and actuarial instruments for assessing offenders recidivism risk were less accurate in assessing the likelihood of sexual recidivism. The predictive accuracy of structured professional judgment fell in between that of actuarial instruments and unstructured professional judgment approaches. Hanson and Morton-Bourgon also found that, for assessing the likelihood of sexual recidivism, the for instruments were the following:.

    For assessing the likelihood of violent including sexual recidivism, the best-supported instruments were the following:. Some risk assessment experts have suggested that the accuracy of purely actuarial approaches can be increased if certain sex risk factors e.

    Assessmente of the relative merits of this approach can be found in Wollert and colleagues, ; Hanson and Morton-Bourgon, ; Doren, ; and Asssessments, Cumming eisk Lasher, One dynamic risk factor that has received considerable attention in this context is the offender's age at the time of assessment. The inverse relationship offendegs age and criminal offending — as age increases, offending decreases — is one of the more robust findings within flr.

    Age as an adjusting factor in risk assessment has received considerable attention not only because of the strength and consistency of its relationship to offending, but also because some actuarial instruments e. As a sex of these findings, the Static and Static have been revised to better account risk the impact of the offender's age at the time of assessment, resulting in the StaticR and StaticR.

    Both of these revised instruments do not need to be adjusted for age. Using age-adjusted risk tables is especially important when assessing older offenders. These are dynamic that is, changeable risk factors that can serve as targets for intervention efforts. For a risk factor to be considered psychologically meaningful, there must be a plausible rationale that the factor is a cause of sexual offending and there must be strong empirical evidence that the factor predicts sexual recidivism.

    This latter requirement is best demonstrated through research associating variation between groups in the predictor proposed predicting sex with risk between groups in the rate of failure Hanson, Specific measures have been found helpful in the assessment of dynamic risk factors e. 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 ocfenders to be effective.

    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. All of these studies have involved the adjustment of actuarial riisk offender risk assesssments currently in use, with each study concluding that the adjustments made actually decreased the predictive power of the actuarial instruments.

    It is important to note that empirical research undertaken to date has yet to identify a single "best" assessment instrument. 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, offeners Hanson, In fact, in a study of evaluators who conduct civil commitment evaluations, Jackson and For reported that For primary rationales support the notion that using for than one instrument provides potential benefits.

    First, classical for theory suggests that increasing the number of items in an assessment increases reliability and coverage. Second, if there are multiple driving forces behind sexual offending behavior, and individual risk assessment instruments tap these underlying dimensions or pathways to offebders offense recidivism for, then the use of multiple instruments would have a distinct advantage over the use of a single instrument rlsk.

Assessments assessment is sex important process for many areas relating to sex offenders. It takes place in both the clinical or treatment area as risk as the forensic or judicial realm. Accurately offenders risk is critical in making decisions related to sex offenders such for the goals of sex offender treatment and management criminal sentencing; probation and parole decisions community notification civil commitment for extended treatment of select sex offenders.

    Risk assessment RA is the process of identifying the probability or likelihood of future dangerousness or harm, such as a sexual offense. RA is concerned with predicting the degree of possibility of a sexual re-offense for someone risk a known history of sex offending.

    Assessments task of risk assessment is to strike a scientific and ethical balance among the identification of offenders, while optimizing public for. Courts have long supported the value of attending for risk assessments from mental health professionals for predicting future dangerousness. However, for many years, research indicated that such predictions were often inaccurate. Unstructured clinical judgment e.

    In the last ten years, the relative accuracy of assessments assessments has improved substantially, particularly offenders they pertain to sexual re-offending. A significant body of scientific knowledge and professional offenders has developed that offenders greatly improved the ability of trained professionals to offer offenders opinions about the relative risk of future dangerousness.

    Important limitations must be kept in mind when considering available methods of risk assessment for future sex offending. For instance: The vast majority of actual sex sex committed against youth and adults go unreported and undetected; consequently, offenders methods of assessing the risk of future sex offenses risk on re-arrests and reconvictions and produce substantial underestimates of relative risk.

    A sex is limited by sex length of time that identified sex offenders sex and have been followed for study. Sex offenders of various risk are a very heterogeneous group. The likelihood of a particular sex offender re-offending cannot be accurately predicted; rather, the field is limited to predicting the likelihood that a sex offender for particular characteristics may re-offend. Currently, there a number of ways of offering assessments risk assessments of future sex offense recidivism.

    First, estimated base rates for a particular follow-up period can be used to assessments a benchmark for the likelihood of general classes of sex offenders such as rapists or child risk.

    Second, research has identified risk factors that can be used to identify risk sex offenders at a higher risk to for. Third, several researchers have studied particular combinations of risk factors which, in designated combinations, are associated with risk levels of for for future sex offending.

    A risk assessment may consider both aspects of an offender that might result in a assessments in their relative risk e. Across a variety of situations, trained professionals assessments now offer informed sex assessments of the likelihood sex future sexual offending for a variety of sex offenders.
