Assessment and management of risk for intimate partner violence by police officers using the Spousal Assault Risk Assessment Guide

Intimate partner violence (IPV) is a crime that is present in all countries, seriously impacts victims, and demands a great deal of time and resources from the criminal justice system. The current study examined the use of the Spousal Assault Risk Assessment Guide, 2nd ed. (SARA; Kropp, Hart, Webster, & Eaves, 1995), a structured professional judgment risk assessment and management tool for IPV, by police officers in Sweden over a follow-up of 18 months. SARA risk assessments had significant predictive validity with respect to risk management recommendations made by police, as well as with recidivism as indexed by subsequent contacts with police. Risk management mediated the association between risk assessment and recidivism: High levels of intervention were associated with decreased recidivism in high risk cases, but with increased recidivism in low risk cases. The findings support the potential utility of police-based risk assessment and management of IPV, and in particular the belief that appropriately structured risk assessment and management decisions can prevent violence.

Assessment and Management of Risk for Intimate Partner Violence by Police Officers Using the Brief Spousal Assault Form for the Evaluation of Risk

The management of intimate partner violence (IPV) typically falls to police. For assistance, officers are increasingly using violence risk assessment tools like the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER). This study replicates the methodology of Belfrage et al. but examines the B-SAFER as used by Swedish police officers when assessing and managing IPV. Results revealed a positive relationship between risk and management. Total scores and overall risk ratings predicted recidivism (AUC [Area under the curve] = .70 and .69, respectively). Finally, a pattern where management recommendations were associated with decreased recidivism in high risk perpetrators but increased recidivism in low risk perpetrators was found. Results validate the use of the B-SAFER by police and reveal mostly comparable findings between the B-SAFER and the Spousal Assault Risk Assessment Guide, as examined by Belfrage et al., but suggest that the B-SAFER may be better suited for police.

Utilization and Implications of the Static-99 in Practice

The Static-99 is the most commonly used risk assessment instrument for sexual violence in North America and its results can affect highly consequential decisions made in the criminal and civil justice systems. Despite its influence, few studies have systematically examined how the Static-99 is used by clinicians in practice. The current study compares the Static-99 ratings of clinicians to those of researchers for 100 adult males who completed an outpatient sex offender treatment program and were followed up over an average of about 4 years. Results showed good agreement between the ratings of clinicians and researchers for total scores on the Static-99, as well as for most individual items. Ratings by clinicians tended to be slightly lower than those made by researchers. The predictive validity of ratings made by clinicians and researchers was very similar and moderate in terms of effect size. In 30 cases, clinicians used discretion to “override” or adjust the Static-99 ratings when making final risk judgments, but the predictive validity of the clinical adjusted ratings was worse than that of the original Static-99 ratings made by clinicians. The need for quality assurance and training are discussed along with the need for clear empirically supported guidelines regarding overrides.

Psychopathy and Stalking

We examined the association between psychopathy, assessed using the Hare Psychopathy Checklist-Revised: Screening Version (Hart et al., Manual for the psychopathy checklist screening version (PCL:SV), 1995), and stalking in 61 men convicted of stalking-related offenses. Psychopathic symptoms were rare, but their presence—especially that of affective deficit symptoms—was associated with victimization of casual acquaintances and with several risk factors from the Guidelines for Stalking Assessment and Management (SAM) (Kropp et al., Guidelines for stalking assessment and management, 2008a), including stalking in violation of supervision orders, degree of preoccupation with victims, and targeting of victims with limited access to external resources. The findings suggest that in spite of their rarity, psychopathic traits may be important in the assessment and management of stalking risk.

Evaluation of a Violence Risk (Threat) Assessment Training Program for Police and Other Criminal Justice Professionals

Although a great deal of research has focused on the development and validation of violence risk (threat) assessment instruments, few studies have examined whether professionals can be trained to use these instruments. The present study evaluated the impact of a violence risk assessment training program on the knowledge, skills, and attitudes of 73 criminal justice professionals, including police officers, civilian support staff, and prosecutors. The program covered principles of violence risk assessment, the nature of mental disorder and its association with violence risk, and the use of various structured professional judgment (SPJ) risk assessment instruments. Comparisons of pre- and post-training evaluations indicated significant improvements on measures of knowledge about risk assessment, skills in the analysis of risk in a case vignette, and perceived confidence in conducting violence risk assessments. Findings support the utility of risk assessment training for criminal justice professionals and the utility of SPJ violence risk assessment instruments generally.

The development and validation of the guidelines for stalking assessment and management

International research has established that stalking is a prevalent problem with serious and often life-threatening consequences for victims. Stalking is also a unique form of violence due to its nature and diversity, making it difficult for criminal justice and health professionals to establish which perpetrators and victims have the greatest need for services and protection. Risk assessment is one way to address these problems but few tools exist. This article describes the development of the Guidelines for Stalking Assessment and Management (SAM), the first risk assessment instrument designed specifically for the stalking situation. Preliminary data are presented, indicating that the SAM has promise for use by professionals working with stalkers and their victims. Results indicated that interrater reliabilities for the SAM risk factors and total scores range from fair to good, and the structural reliability of the SAM is sound. Moreover, the SAM showed good concurrent validity when compared with two other measures of violence propensity: the Psychopathy Checklist Screening Version (PCL:SV) and the Violence Risk Appraisal Guide (VRAG). Limitations of the study are discussed, especially those related to the difficulties inherent in file-based research, and suggestions for future research are offered.

The characteristics and violence risk management of women arrested by the police for intimate partner violence

Research and management efforts in the area of intimate partner violence (IPV) have primarily focused on male perpetrators and female victims, resulting in more limited knowledge of female IPV perpetrators and their male victims. In the current study the violence risk assessments of police officers were examined in order to outline the characteristics of female perpetrators of IPV and their male victims. In addition, the officers’ assessments of violence risk and proposed risk management strategies are presented. Results reveal some similarities between the female perpetrators and male victims and their more studied counterparts. However, differences appear to be present in the perceived violence risk posed by the perpetrators and the violence risk management strategies proposed to reduce that risk and protect the victim. The results suggest a need for further research in the area, particularly with respect to the violence risk assessment and management of female IPV perpetrators.

Assessing Violence Risk Among Female IPV Perpetrators: An Examination of the B-SAFER

Intimate partner violence (IPV) is a global problem and one in which frontline assessment and management falls primarily to police. Although IPV is often conceptualized as a male-perpetrated crime, evidence substantiates female IPV perpetration and increased arrest rates, raising important issues for police. This article examines police use of the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER; Kropp, Hart, & Belfrage, 2005, 2010), a violence risk assessment tool for IPV. The B-SAFER was used to assess and manage 52 women arrested for IPV. When compared to Belfrage and Strand (2008), who examined men arrested for IPV in the same sample, women possessed fewer risk factors. Risk factors were related to summary risk judgments, although differences existed between genders and risk judgments were not related to management recommendations. Results suggest that risk factors, in addition to those in the B-SAFER, are required to assess risk for female IPV.

Is My Test Valid? Guidelines for the Practicing Psychologist for Evaluating the Psychometric Properties of Measures

A general logic for data-based test evaluation based on Slaney and Marauns (2008) framework is described. On the basis of this framework and other well-known test theoretic results, a set of guidelines is proposed to aid researchers in the assessment of the psychometric properties of the measures they use in their research. The guidelines are organized into eight areas and range from general recommendations, pertaining to understanding different psychometric properties of quantitative measures and at what point in a test evaluation their respective assessments should occur, to clarifications of core psychometric concepts such as factor structure, reliability, coefficient alpha, and dimensionality. Finally, an illustrative example is provided with a data-based test evaluation of the Hare Psychopathy Checklist-Revised (Hare, 1991) as a measure of psychopathic personality disorder in a sample of 384 male offenders serving sentences in a Canadian correctional facility.

An examination of violence risk communication in practice using a structured professional judgment framework

The increased use of violence risk assessment tools in professional practice has sparked the development of best-practice guidelines for communicating about violence risk. The present study examined 166 pre-sentence reports, authored by clinicians and probation officers, to determine the extent to which they are consistent with those guidelines. We examined the frequency with which reports contained information about five topics: the presence of risk factors; the relevance of risk factors; scenarios of future violence; recommended management strategies; and summary risk judgments. Analyses revealed that the topics addressed most frequently in reports were the presence of risk factors and recommended management strategies, but none of the five topics was addressed consistently, completely, or clearly in reports. This was especially the case for probation reports. The findings highlight the need to improve practice through better implementation of guidelines for risk communication. Also needed is research on the extent to which information in risk communications is comprehended, accepted, and used by various stakeholder groups.
