When do people report crime to the police? Results from a factorial survey design in the Netherlands, 2010

Objectives  

In this paper we assess to what extent factors of the reporting process affect the willingness to report crime to the police. The focus is on the following factors: (1) duration and flexibility (i.e. possibility to report outside office hours), (2) method of reporting (i.e. phone, Internet or police station), (3) anonymous reporting, and (4) encouragement by police officers.

Effectiveness of a risk–need–responsivity‐based treatment program for violent and sexual offenders: Results of a retrospective,quasi‐experimental study

Purpose

Relapse prevention is an important goal in correctional settings. Although there is strong evidence for the effectiveness of certain treatment programs for juvenile offenders, those for adults lack such evidence. This study evaluated the effectiveness of a risk–need–responsivity (RNR)‐based intervention.

Methods

A quasi‐experimental, observational study design and cox regression analysis were used to compare treated violent and sexual offenders (n = 171) with untreated offenders (n = 241).

Results

Both groups were observed for an average of 7.9 years. Recidivism rates of treated offenders (11.7%, n = 20) were similar to those of control offenders (15.8%, n = 38; p = .25). When controlling for confounding variables, the hazard of recidivism in the treatment group was 5.2% lower than that in the control group. Subdividing the treatment group resulted in lower hazard ratios for offenders still in therapy when released and offenders cancelling therapy. However, none of the group differences was statistically significant.

Conclusion

Our results show that control and RNR‐based treatment groups had comparable recidivism rates with a trend towards a positive treatment effect, especially for people in outpatient treatment. However, criminal history, age at the start of follow‐up, and actuarial risk of recidivism were significantly associated with recidivism. Future research needs to apply elaborate methodological approaches to detect robust treatment effects and consider different criteria of treatment effectiveness. Furthermore, the influence of prison climate, motivational factors, intervention quality, and factors supporting the success of outpatient treatment should be considered in future studies of larger offender samples.     

A taxonomy of collaborative governance: a guide to understanding the diversity of international and domestic conservation accords

Partially in response to the increasing complexity of governance structures in the international environmental arena, international scholars have adopted a distinction between “Type 1” and “Type 2” international agreements. The former refer to agreements between governments, whereas the latter refer to agreements between governments and nonstate actors. While useful, this distinction offers only a partial taxonomy of the diversity of collaborative governance, and fails to incorporate “Type 3” dynamics among nonstate actors. As an initial attempt at sorting out the wide array of collaborative governance structures both domestically and across international borders, we propose a 3 × 3 matrix based on two typologies, one institutional (governmental, collaborative, nonstate), the other geopolitical (domestic, transborder, interstate/transnational). The result is a classification system of nine types of both domestic and international governance. In addition to identifying fundamental differences among the myriad forms of governance, the matrix reveals how the “softening of sovereignty” occurs in practice.

Drunk and dangerous: a randomised controlled trial of alcohol brief intervention for violent offenders

To assess the effectiveness of an alcohol brief intervention administered to violent offenders in a judicial (Magistrates’ court) setting, a randomised controlled trial was conducted. Participants (n = 269) were men aged 16–35 years, who resided within a 30-mile radius of Cardiff, UK, and who had been sentenced for a violent offence committed whilst intoxicated with alcohol. Recruitment occurred on-site. Participants were randomly allocated to receive an alcohol brief intervention (n = 135) or to a control group (n = 134). Objective measures comprised re-offending and injury rates. Self-reported outcome measures comprised Alcohol Use Disorders Identification Test (AUDIT); number of drinking days in the past 3 months; total weekly standard units of alcohol; and stage of change with respect to alcohol consumption (as measured by the Readiness to Change Questionnaire). Participants were followed up 3 months (n = 234; 87%) and 12 months (n = 202; 75.1%) after sentence. No significant between-group differences were observed in any of the alcohol measures or in re-offending. Injury was significantly less likely in offenders who had received the intervention (27.4%) than those who had not [39.6%; 95% confidence interval (CI) = −0.23, −0.009]. At 3-month follow-up, significantly more participants in the intervention group (31%; n = 37) than control group (16%; n = 18) demonstrated an increase in their readiness to change drinking behaviour (χ² = 8.56; df = 2; P = 0.014), but this did not persist at 12-month follow-up.

Spatial displacement and diffusion of benefits among geographically focused policing initiatives: a meta-analytical review

Objectives  

To undertake a systematic review of the extent to which geographically focused policing initiatives appear to displace crime (simply relocate it to other places) or diffuse benefits (lead to reductions elsewhere).     

Court evaluations of young children's testimony in child sexual abuse cases

Purpose

Prosecutors working with child sexual abuse (CSA) cases involving young children have raised concerns that reliability criteria from the Supreme Court of Sweden are holding children's testimony to impossible standards (e.g., expecting the child's testimony to be long, rich in detail and spontaneous). This study aimed to address these concerns by investigating how District Courts and Courts of Appeal employ said criteria in their testimonial assessments of young child complainants.

Methods

Court documents from District Courts (n = 100) and Courts of Appeal (n = 45) in CSA cases involving 100 children age 7 years and under were analysed with respect to the courts’ testimonial assessments.

Results

Testimonial assessments were more frequently referenced in acquitting verdicts and in cases with evidence of low corroborative value. Richness in detail was the most frequently used reliability criterion, followed by spontaneity. Most criteria were used in favour of the children's testimony. However, the length criterion was typically used against the reliability of the children's testimony.

Conclusions

Our findings confirm prosecutors’ concerns that criteria from the Supreme Court are frequently used in evaluations of young children's testimony. This is troublesome, as some criteria do not correspond to current research on young children's witness abilities. For example, compared to testimony given by older children or adults, testimony provided by a young child is typically not long or rich in detail. We encourage prosecutors to extend their own knowledge on young children's capability as witnesses and present this to the court.

The Dynamic Prediction of Criminal Recidivism: A Three-wave Prospective Study

A three-wave, prospective panel design was used to assess the extent to which static and dynamic risk factors could predict criminal recidivism in a sample of 136 adult male offenders released from Canadian federal prisons. Static measures were assessed only once, prior to release while dynamic measures were assessed on three separate occasions: pre-release, 1 month, and 3 months post-release. Recidivism was coded during an average of 10.2-month follow-up period (SD = 19.2). A series of Cox regression survival analyses with time-dependent covariates and Receiver Operator Characteristic (ROC) analyses were conducted to assess predictive validity. Although the combined static and time-dependent dynamic model (AUC = .89, CI = .81–.93) significantly (p < .01) outperformed the pure static model (AUC = .81, CI = .73–.87) the confidence intervals did overlap to some extent. Implications for dynamic risk assessment and management are discussed.
