Dynamic risk scales have largely been evaluated using singular assessment scores, including those obtained at the start of supervision. While this approach includes assessment of dynamic factors, it ignores changes with reassessment, failing to examine whether an instrument is truly dynamic in nature. This is problematic, as proximal risk assessments have consistently outperformed baseline assessments in the prediction of recidivism.

One creative way that Departments of Corrections offset costs is by relying on volunteers. Prison volunteers are a heterogeneous group, who provide various programs to incarcerated populations. One unique subset of prison volunteers are peer mentors, who are individuals who have experienced criminal justice interventions and have desisted from criminal activities.

Due to recent legal cases highlighting a lack of cross-ethnicity validity research using correctional risk assessment tools, we evaluated psychometric properties of Dynamic Risk Assessment for Offender Re-entry (DRAOR) scores across Māori ( = 1,812) and New Zealand (NZ) European samples ( = 1,211) in Aotearoa NZ. Using routine administrative data, our analyses suggested scoring properties were invariant across ethnicity for 15 of 19 items. Discrimination properties were also equivalent, but we observed a higher recidivism base rate among Māori participants, consistent with official statistics.

There are clinical practice and operational reasons why it may be appropriate to primarily focus on general risk factors when supervising people convicted of sexual crime in the community. General risk domains may be particularly relevant when supervision officers engage in frequent reassessment of acute dynamic risk factors. We tested the ability of a case management tool, the Dynamic Risk Assessment for Offender Re-entry, to discriminate community based, short-term general (all outcome) recidivism versus nonrecidivism among people convicted of sexual crime ( = 562).

Objective: Clinicians often rely on readily observable intermediate outcomes (e.g., symptoms) to assess the likelihood of events that occur outside of treatment (e.

Objective: In community-based corrections, reassessment of dynamic risk factors improves the prediction of recidivism relative to initial risk assessment at the time of release. However, there is less evidence for predictions of violent recidivism. We examined whether reassessment proximity or aggregation of reassessments improved the prediction of imminent violence in a sample of paroled individuals on community supervision.

Intimate partner violence (IPV) is among the most common acts of violence against women worldwide, making it a major global threat to women's health and safety. The assessment and management of IPV offenders are therefore vital tasks in criminal justice systems. The current study examined whether the DRAOR, a general case management tool, was useful for supervising 112 male IPV offenders in Iowa, United States.

A dynamic risk factor is a variable that can change across time, and as it changes, there is a corresponding change in the likelihood of the outcome. In corrections, there is evidence for dynamic risk factors when relatively more proximal reassessments enhance predictive validity for recidivism. In this article, we tested the proximity hypothesis with longitudinal, multiple-reassessment data gathered from 3,421 individuals supervised on parole in New Zealand (N = 68,667 assessments of theoretically dynamic risk factors conducted by corrections case managers).

Objective: Specific responsivity features are not directly targeted in offender rehabilitation programs but may impact a client's receptivity. We investigated if two features may explain why high-quality correctional programs do not uniformly impact all high-risk, high-needs clients.

Hypotheses: The current study was exploratory.

Both the Risk-Needs-Responsivity (RNR) and Structured Professional Judgment (SPJ) risk assessment approaches assume that a strong relationship exists between crime-causing and crime reducing factors. Using a probation sample, the present article examines whether crime-causing and crime-reducing factors correspond. Probationers completed questionnaires where they were asked what factors were crime-causing and what factors were crime-reducing.

Advances in criminal risk assessment have increased sufficiently that inclusion of valid risk measures to anchor assessments is considered a best practice in release decision-making and community supervision by many paroling authorities and probation agencies. This article highlights how decision accuracy at several key stages of the offender's release and supervision process could be further enhanced by the inclusion of dynamic factors. In cases where the timing of release is discretionary and not legislated, the utilization of a validated decision framework can improve transparency and potentially reduce decision errors.

Objective: Exposure to antisocial others within treatment group sessions may have negative impact. We extend prior research with adolescents by examining rehabilitation group composition among adult male incarcerated offenders.

Method: Data were gathered from institution files of rehabilitation completers (N = 1,832; M age = 33.

Many inmates do not respond favorably to standard treatments routinely offered in prison. Executive cognitive functioning and emotional regulation may play a key role in treatment responsivity. During intake into treatment, inmates (N = 224) were evaluated for executive functioning, emotional perception, stress reactivity (salivary cortisol), IQ, psychological and behavioral traits, prior drug use, child and family background, and criminal histories and institutional behavior.

The treatment of violent offenders has evolved in recent years, shifting from interventions focused on anger management to those incorporating social information processing skills. The present study was a multimethod evaluation of one such program, the Persistently Violent Offender program. A total of 256 Canadian male violent offenders participated in the study; 70 Persistently Violent Offender program completers were compared to two control groups (n(1) = 33, n(2) = 105) who completed an alternate program and to 48 offenders who failed to complete either program.

The present study investigated 154 consecutive admissions to the Regional Treatment Center (Ontario) Sex Offender Treatment Program with reference to psychopathy and outcome. Ratings of treatment behavior, as well as clinical judgments as to whether risk was reduced, were coded based on treatment reports. With reference to Psychopathy Checklist-revised (PCL-R) scores, survival analyses indicated that high scorers recidivated at significantly higher rates than low scorers.

A sample of 519 sexual offenders who were consecutive admissions to the Ontario Region of Correctional Service of Canada (CSC) were assessed with reference to a large series of variables thought to be related to sexual offending. We grouped these variables into five domains: criminality, social competence, sexual deviance, substance abuse and treatment readiness. We standardized scores on each of these domains to facilitate the calculation of total scores for each domain.

Hostage takings and forcible confinements are rare phenomena within our Canadian institutions. However, when they occur they cause enormous psychological and/or physical harm. A review of the literature revealed that no previous research on hostage takings or forcible confinements in a prison setting has been published.

Notwithstanding significant progress in the areas of risk appraisal and treatment of sex offenders, the contention is that further advancements could be realized through attention to research on non-sex offenders. Specifically, it is proposed that sex offenders share many characteristics of non-sex offenders and research with these populations should be integrated, not discrete. In particular, work in the area of multi-method offender assessment regarding criminogenic need is highlighted to suggest common treatment targets for sex offenders and non-sex offenders.

A sample of 337 offenders who received treatment in a variety of sex offender treatment programs in the Ontario region of Correctional Service Canada between 1993 and 1998 were divided based on the highest intensity sex offender programming that they received (low, moderate, and high). The three groups were compared with reference to a variety of actuarial risk assessment measures, criminogenic factors, and the number and type of treatment programs completed. It was hypothesized that the high-intensity group would have more criminogenic risk factors, higher actuarial scores, and participate in more treatment programs than both the moderate- and low-intensity groups.
