Random breath testing in Queensland and Western Australia: examination of how the random breath testing rate influences alcohol related traffic crash rates

In this paper we explore the relationship between monthly random breath testing (RBT) rates (per 1000 licensed drivers) and alcohol-related traffic crash (ARTC) rates over time, across two Australian states: Queensland and Western Australia. We analyse the RBT, ARTC and licensed driver rates across 12 years; however, due to administrative restrictions, we model ARTC rates against RBT rates for the period July 2004 to June 2009. The Queensland data reveals that the monthly ARTC rate is almost flat over the five year period. Based on the results of the analysis, an average of 5.5 ARTCs per 100,000 licensed drivers are observed across the study period. For the same period, the monthly rate of RBTs per 1000 licensed drivers is observed to be decreasing across the study with the results of the analysis revealing no significant variations in the data. The comparison between Western Australia and Queensland shows that Queenslands ARTC monthly percent change (MPC) is 0.014 compared to the MPC of 0.47 for Western Australia. While Queensland maintains a relatively flat ARTC rate, the ARTC rate in Western Australia is increasing. Our analysis reveals an inverse relationship between ARTC RBT rates, that for every 10% increase in the percentage of RBTs to licensed driver there is a 0.15 decrease in the rate of ARTCs per 100,000 licenced drivers. Moreover, in Western Australia, if the 2011 ratio of 1:2 (RBTs to annual number of licensed drivers) were to double to a ratio of 1:1, we estimate the number of monthly ARTCs would reduce by approximately 15. Based on these findings we believe that as the number of RBTs conducted increases the number of drivers willing to risk being detected for drinking driving decreases, because the perceived risk of being detected is considered greater. This is turn results in the number of ARTCs diminishing. The results of this study provide an important evidence base for policy decisions for RBT operations.

Viewing systematic reviews and meta-analysis in social research through different lenses.

Systematic reviews and meta-analyses are used to combine results across studies to determine an overall effect. Meta-analysis is especially useful for combining evidence to inform social policy, but meta-analyses of applied social science research may encounter practical issues arising from the nature of the research domain. The current paper identifies potential resolutions to four issues that may be encountered in systematic reviews and meta-analyses in social research. The four issues are: scoping and targeting research questions appropriate for meta-analysis; selecting eligibility criteria where primary studies vary in research design and choice of outcome measures; dealing with inconsistent reporting in primary studies; and identifying sources of heterogeneity with multiple confounded moderators. The paper presents an overview of each issue with a review of potential resolutions, identified from similar issues encountered in meta-analysis in medical and biological sciences. The discussion aims to share and improve methodology in systematic reviews and meta-analysis by promoting cross-disciplinary communication, that is, to encourage ‘viewing through different lenses’.

Comparing Police and Public Perceptions of a Routine Traffic Encounter

Police perceptions of procedural justice are less well understood than citizen perceptions. Our paper compares the views of police officers and citizens of a routine Australian policing encounter, the Random Breath Test. We examine perceptions of two versions of their encounter: a business as usual and a more explicitly procedurally just interaction. Our results indicate that the procedurally just version affected the views of police officers, but not drivers, regarding the reasons for conducting Random Breath Tests. It also appears that police officers believe that the encounter has a greater impact on drivers’ views than the drivers report themselves. This study has important implications for policing as it demonstrates that incorporating procedural justice within police-citizen interactions affects police officers as well as the citizens. It also highlights the importance of using external (e.g., larger community) measures, in addition to internal measures (e.g., within police organization), when assessing the effectiveness of police organizations to ensure a more complete picture.

Optimising the length of random breath tests: Results from the Queensland Community Engagement Trial

Research suggests that the length and quality of police–citizen encounters affect policing outcomes. The Koper Curve, for example, shows that the optimal length for police presence in hot spots is between 14 and 15 minutes, with diminishing returns observed thereafter. Our study, using data from the Queensland Community Engagement Trial (QCET), examines the impact of encounter length on citizen perceptions of police performance. QCET involved a randomised field trial, where 60 random breath test (RBT) traffic stop operations were randomly allocated to an experimental condition involving a procedurally just encounter or a business-as-usual control condition. Our results show that the optimal length of time for procedurally just encounters during RBT traffic stops is just less than 2 minutes. We show, therefore, that it is important to encourage and facilitate positive police–citizen encounters during RBT at traffic stops, while ensuring that the length of these interactions does not pass a point of diminishing returns.

Social identity and procedural justice in police encounters with the public: results from a randomised controlled trial

The role of social identity in shaping citizen views of police is central to the group-value model (GVM). The GVM suggests that the relationship between public perceptions of fair treatment and views of police legitimacy will be tempered by social identity. Our paper employs a randomised field trial of procedural justice dialogue – the Queensland Community Engagement Trial – to test the role of social identity in the GVM. Under randomised field trial conditions we find that social identity is connected to perceptions of procedural justice and legitimacy, but that it does not moderate the effect of procedural justice on legitimacy. We discuss the implications of this finding, concluding that when police use procedurally just dialogue in encounters with the public, they can enhance perceptions of police, regardless of social identification.

Reducing Truancy and Fostering a Willingness to Attend School: Results from a Randomized Trial of a Police-School Partnership Program

Truancy is a major social issue that is linked to a range of poor outcomes across the life course, including poor educational outcomes, drug and alcohol abuse, and antisocial behavior. Interventions that seek to reduce truancy problems range from school-based police officers to programs that reward good attendance to community-based interventions. This study reports primary outcome results of a randomized trial of a collaborative, police–school partnership that sought to reduce truancy and increase students’ willingness to attend school. Using school attendance and students’ self-report survey data, we find that the police–school partnership intervention shows promise for reducing truancy and improving students’ willingness to attend school. We conclude that police–school partnerships that foster the willingness of young people to attend school should be examined in future evaluation research and be considered in the development of truancy prevention programs.

Truancy Intervention Reduces Crime: Results from a Randomized Field Trial

Educational attainment is a fundamental cornerstone to success throughout the life-course. As a result, ensuring that young people remain in school and are not truant is critical. Although the importance of truancy as a risk factor for many adverse outcomes, including crime, has been well-documented, much less methodologically rigorous work has been undertaken to evaluate potentially promising prevention and intervention strategies. This paper uses a randomized field trial method to test how a partnership between police and schools targeting truancy impacts offending in a sample of high-risk truanting young people. We find that the truancy intervention reduces offending and we discuss the implications for practice and directions for future research.

The Coproduction of Truancy Control: Results from a Randomized Trial of a Police–Schools Partnership Program

Objectives: To evaluate, under randomized field trial conditions, the deterrent effects of a police–school partnership, called the Ability School Engagement Program (ASEP). The partnership sought to co-produce truancy reduction by actively engaging parents and their truanting children in a group conference dialogue that was designed to increase parental and child awareness of the truancy laws (and the consequences of noncompliance), and thereby foster students’ willingness to attend school. Methods: Using a randomized field trial design, 102 truanting young people were randomly allocated to a control, business-as-usual condition (n = 51), or the ASEP experimental condition (n = 51). In this paper, we use mixed model ANOVA and multiple regression analysis of self-report survey data from both students and their parents to assess differences between the experimental and control group on parental perceptions of prosecution likelihood and student willingness to attend school. We use qualitative analysis of the group conference transcripts to examine how the intervention affected these factors. Results: Our results demonstrate that the police–school partnership intervention increased parental awareness of prosecution likelihood, which moderated students’ self-reported willingness to attend school. Conclusions: We conclude that police–school partnerships that engage parents and their children to better understand the laws pertaining to school attendance are a promising approach for co-producing the reduction of truancy.

Changing the Relationship Between Impulsivity and Antisocial Behavior: The Impact of a School Engagement Program:

This study examines the extent to which a third-party policing experiment designed to prevent truancy in disadvantaged adolescents is able to weaken the effect of impulsivity on self-reported antisocial behavior over time. Data are used from the Ability School Engagement Program (ASEP), a randomized controlled trial of 102 high truant youth from Brisbane, Australia who were followed for 2 years postrandomization. We find that ASEP weakened the effect of impulsivity on the diversity of self-reported antisocial behavior throughout the study for those in the experiment. This study provides evidence that an intervention that was designed to prevent truancy has the additional benefit of hindering the relationship between impulsivity and self-reported antisocial behavior variety.
