Deterrence, punishment severity and drink-drivingBriscoe, Suzanne Marie, Social Science & Policy, UNSW January 2005 (has links)
This thesis tests one of the major propositions of deterrence theory: that increases in the severity of punishment can reduce the likelihood of offending. To this end, a case study in which the statutory penalties were doubled for almost all drink-driving offences in New South Wales, Australia, is examined. Two quasi-experimental studies were undertaken to assess the impact of these legislative changes: an interrupted time-series analysis of road crash rates (Study 1) and an analysis of drink-driving reoffending rates before and after the penalty changes were implemented (Study 2). Study 1 showed a significant increase in a surrogate measure of alcohol-related road crashes after the tougher drink-driving penalties were introduced. Further analyses suggested that this increase was driven primarily by a secular rise in non alcohol-related crashes that coincided with the policy???s implementation. Two possible conclusions about the deterrent effect of the policy are drawn from these findings: (1) that there was a reduction in alcohol-related road crashes which was overwhelmed by the rise in non alcohol-related crashes occurring around the same time or (2) that there was no change in crash rates. Study 2 found that drink-drivers who were convicted under the new penalty regime were less likely, and took longer, to reoffend than drink-drivers convicted before the introduction of the new penalties. This reduction in reoffending was only apparent for drink-drivers residing in country and regional areas and was small in magnitude.These latter findings are consistent with the possibility that the penalty changes coincided with a reduction in alcohol-related crashes but suggest that any decrease is likely to have been relatively small. A third study using a scenario-based survey methodology was also undertaken to examine the relationship between legal sanctions and willingness to drink-drive, controlling for other factors. The results of this study showed that participants who were more knowledgeable about drink-driving penalties were less likely to state that they would offend in the drink-driving scenario than participants who were less knowledgeable about the law. The implications of these findings for deterrence theory and criminal justice policy are discussed.

Some forensic aspects of chemical tests for alcoholBayly, Ronald Cecil January 1960 (has links)
The problem surrounding the ever-increasing toll of death and injury arising from road accidents is one which is receiving increasing attention as the number of vehicles on the road continues to rise. While it has not been possible to isolate any one factor as the sole or even primary cause of road accidents, several surveys have shown that in many accidents alcohol has been a contributory factor by affecting the faculties of the driver of pedestrian. The thesis then goes on to discuss factors causing individual differences in response to the same blood alcohol concentration and the correlation between impairment of driving and blood alcohol concentration.

Reducing the drink driving road toll: A case study in integrating communication and social policy enforcement.Snitow, Samantha, samantha.snitow@alumni,tufts.edu January 2004 (has links)
This thesis presents a case study of the drink drive initiatives, including marketing communications, legislation and enforcement practices implemented in the state of Victoria (Australia) between 1989-2000. It has been argued that the 51% reduction in road toll was related to these initiatives. In order to explore the veracity of these claims, a holistic case study approach was adopted. In addition to an examination of the communications tactics and extant practices of enforcement agencies, the study involved interviews with two distinct groups: professionals in various fields pertaining to road safety, and members of the general Victorian driving community. The focus of this work was on the advertising and communications campaigns that were run by the Transport Accident Commission from 1989-2000; however the policy and enforcement initiatives were also examined in terms of their potential impact on the lowering of the road toll. Suggestions for the improvement of policy and communication strategies within a social marketing context are made.

Influencing recidivist drink drivers' entrenched behaviours : the self-reported outcomes of three countermeasuresFreeman, James Edwin January 2004 (has links)
Concern remains regarding the efficacy of drink driving countermeasures to produce lasting change for repeat offenders, as a wide array of countermeasures have been developed that demonstrate varying levels of success in reducing re-offence rates. This thesis proposes that the collection and examination of repeat offenders' self-reported perceptions, experiences and behavioural changes that result from completing court-ordered interventions can provide valuable contributions to the development of effective sentencing strategies. As a result, the program of research implemented a mixed-method design to investigate the self-reported impact of legal sanctions, a drink driving rehabilitation program, and alcohol ignition interlocks on key outcome measures for a group of recidivist drink drivers.-----
Study One incorporated a cross-sectional design to examine the deterrent effect of traditional legal sanctions (e.g., fines and licence disqualification periods), non-legal sanctions, alcohol consumption, recent offending behaviour(s), and the actual severity of sanctions on perceptual deterrence and intentions to re-offend. The study involved face-to-face and telephone interviews with 166 repeat offenders. The analysis indicated that participants perceived legal sanctions to be severe, but not entirely certain nor swift.-----
In Study One, self-reported recent drink driving behaviours and alcohol consumption levels were identified as predictors of future intentions to drink and drive. The results suggest that habitual behaviours are difficult to change, and heavy alcohol consumption levels increase the probability of re-offending. At a bivariate level, three non-legal sanctions were negatively associated with intentions to re-offend but were not predictors of future intentions to drink and drive in the model. In addition, a relationship was not evident between: (a) the size of the penalties and perceptions of sanction severity or future intentions to drink and drive, and (b) the number of previous convictions and self-reported deterrence. The findings of the study confirm the popular assumption that some repeat offenders are impervious to the threat and application of legal sanctions.-----
Study Two examined the stages of change and self-efficacy levels of 132 repeat offenders - who were all involved in Study One - while they completed an 11 week drink driving rehabilitation program. A repeated measures design was implemented to focus on the impact of the intervention on a number of salient program outcomes such as participants' motivations and self-efficacy levels to control and change their drinking and drink driving behaviour(s). Prior to program commencement, the majority of participants were motivated to change their drinking driving, but not their drinking. The sample also reported high self-efficacy levels to control the two behaviours, but did not have high expectations of the effectiveness of the program.-----
Upon completion of the program, significant increases were evident in motivations to change drinking and drink driving behaviours, and a large percentage of participants reported a positive appraisal of the effectiveness of the intervention. Program completion also resulted in a reduction in self-reported alcohol consumption levels, yet the majority of the sample continued to consume harmful levels of alcohol. Self-efficacy levels remained high, although a notable finding was that participants reported higher levels of control over their drinking rather than drink driving behaviours. In general, Study Two provided a positive perspective of the capacity of a drink driving rehabilitation program to produce change for a group of repeat offenders.-----
Study Two extended a small body of research and examined the effects that mandated program enrolment has on motivations to change, as well as expectations and appraisals of program effectiveness. Contrary to predictions, mandated participants did not report lower levels of motivation to change drinking and drink driving compared to voluntary attendees, but did indicate lower expectations of the effectiveness of the program, as well as being willing to engage in the program. Furthermore upon program completion, mandated participants also reported lower appraisals of the effectiveness of the program, but this factor was not associated with intentions to re-offend or non-program completion. Rather, not successfully completing the program appeared linked with being unwilling to change drinking behaviours.-----
Study Three involved a longitudinal case-study design that utilised both quantitative and qualitative data to conduct one of the first examinations of the impact of alcohol ignition interlocks on a group of recidivist drink drivers from a users' perspective. The study investigated 12 participants' self-reported perceptions and experiences of using an interlock and the effect that the device had on key program outcomes such as drinking levels, operational performance, circumvention attempts and general beliefs regarding the effectiveness of the device in comparison to traditional legal sanctions.-----
Participants reported positive appraisals regarding the effectiveness of the device as qualitative themes emerged concerning the educational and practical benefits of interlocks. However, closer examination of individual interlock performances revealed each participant had attempted to start their vehicle after consuming alcohol, and a smaller sample of three drivers were regularly attempting to start their vehicle after drinking. The combination and analysis of self-reported and downloaded interlock data revealed four main themes: (a) initial operational difficulties, (b) a general unwillingness to reduce alcohol consumption levels, (c) an unwillingness to acknowledge/recognise that interlock breath violations resulted from drinking, and (d) an overall decline in the frequency of interlock breath violations over the interlock installation period. Similar to Study Two, a notable finding was that half the sample was still consuming harmful levels of alcohol upon program completion.-----
Taken together, the results of the program of research highlight that repeat offenders' entrenched behaviours, such as drinking and drink driving, are resistant to change and that multi-modal interventions are required if the drinking and driving sequence is to be broken for this population. The findings have direct implications for the sentencing and management of repeat offenders and the development of countermeasures that attempt to produce long-term behavioural change.

Message processing of fear-based anti-drink driving advertisementsFry, Marie-Louise January 2006 (has links)
While overall road deaths in Australia have fallen since the late 1980's and the impact of road-safety advertising appears to be positive, alcohol-related road fatalities remain the leading cause of death among young Australian adults. Fatality and injury rates continue within this cohort despite increases in alcohol-related knowledge, continuing education efforts in the Australian school system, increased funding for police enforcement and high media presence of road safety advertising (Peder et al 2004). Notwithstanding advances in communication technologies, highly graphic, emotional, shock style television advertising remains the primary medium for road safety message dissemination. Rather than targeting those highest at-risk for drink driving, road safety advertisements typically target an undifferentiated general audience. To date understanding the process by which road safety advertising influences attitudes and behaviour has been the centre of fear arousal research. Nonetheless, there has been little examination of how young adults who differ in drink-driving risk-propensity (high versus low) respond to and process anti-drink driving advertisements designed to modify an avoidable behaviour. Taking a receiver oriented approach, the focus of this study examines how young adult, novice drivers who differ in 'need-for-sensation' (NFS) risk propensity respond to, and process, anti-drink driving advertisements that differ in arousal capacity (i.e. high, low sensation-value). The investigation was conducted in two stages: Study 1 (qualitative) and Study II (quantitative). Study I, the qualitative phase, explored by focus group interviews attitudes, perceptions, beliefs and experiences of sixty young adults aged 18 to 25 years towards alcohol consumption, drink-driving, and anti-drink driving advertising. The major qualitative finding is that young adults characterise drink-driving as a rational, deliberate, planned and accepted behaviour. Young adults were aware of the choices available for not drinking and driving and were aware of the health, social and physical (self and property) risks associated with alcohol consumption and associated behaviours. Nonetheless, the short-term personal experiences of revelry and group cohesion were more pertinent to them on an everyday basis. Alcohol consumption and drink-driving behaviour did not appear to differ between university and nonuniversity students or gender, yet there were differences in attitudes and behaviour across the degree studied within the university cohort. Study II, the quantitative phase, was segmented into three sections. First, the study provides empirical support for NFS as a relevant a priori individual differences segmentation variable for differentiating between those more likely, versus less likely, to engage in responsible drink-driving behaviour. As expected low NFS individuals were more likely to not drink and drive. Second, findings support an interaction effect between an advertisement's sensation value and individual differences variable, NFS, on response outcomes. High NFS individuals engaged in higher levels of adaptive appraisal on the high sensation-value advertisement condition as compared to the low sensationvalue advertisement condition. Low NFS individuals did not discriminate across either advertisement condition. Adaptive appraisal was not counteracted by a corresponding increase in maladaptive appraisal. Both high and low NFS individuals viewed the high sensation-value advertisement condition with high levels of perceived threat and viewed the low sensation-value advertisement with higher levels of perceived efficacy. Yet, although high NFS individuals viewed the high sensation-value advertisement with high levels of threat they simultaneously viewed this advertisement with low levels of perceived efficacy. Third, NFS was not found to be a strong predictor moderating the relationship between message processing (cognitive, sensory, narrative) and response outcomes. The findings indicate strong support for a direct relationship between two modes of message processing: cognitive and narrative processing and response outcomes. Message recipients processed anti-drink driving advertisements via two routes to persuasion. There was stronger cognitive processing evident on advertisements possessing high arousal capacity, whereas stronger narrative processing was evident on low arousal capacity advertisements. This study suggests that those advertisements that possess high arousal capacity have the capability of facilitating attention to the central argument, the consequences of drinking and driving, as well as how drinking and driving may affect the message recipients' life. Alternatively, those messages that impart high levels of rational information have the capability of increasing attention to the peripheral cues in the message. It is also suggested that different styles of message processing, central versus peripheral, act in a synergistic way to influence response outcomes which indicates that there is no single route to persuasion. Individuals process messages in a complex manner attending to various signals in order to evaluate various components of the message. For road safety practitioners and social marketers the results of this study illustrates practical benefits for the design of anti-drink driving advertisements based on the segmentation variable NFS. The finding that high NFS individuals require advertisements that possess high levels of arousal capacity (i.e.: high in sensation-value) is an important development. Importantly, low NFS individuals do not discriminate in accepting the recommendations of advertisements that differ in arousal capacity clearly suggests that they accept messages regardless of their arousal capacity. This finding indicates that the goal of road traffic authorities, advertising agencies and social marketers should be directed towards targeting high NFS individuals who are more atrisk for a drink-drive fatality. That message recipients process anti-drink driving messages via two routes to persuasion indicates that message designers need to consider the mix between the sensation-value of the message and consideration of the way message recipients' process the message, i.e. via central/systematic versus peripheral/heuristic components of the advertisement. Further investigation into the dual processing of anti-drink driving advertisements once individuals are exposed to the message is warranted to further understand the psychological processes influencing message processing. The findings of this research have important implications for both practitioners and academics. This research has provided an insight into the complexity of young adult's response outcomes and message processing of fear-based anti-drink driving messages.

Organisational barriers and facilitators to the effective operation of Random Breath Testing (RBT) in QueenslandHart, Susan January 2004 (has links)
Random breath testing (RBT) is one of the most successful drink driving countermeasures employed by police in Australia. Its success over the years has been evidenced by reductions in drink driving behaviour, reductions in alcohol-related crashes and fatal crashes and a corresponding community-wide increase in the disapproval of drink driving. Although a great deal of research has been able to highlight the relationship between increased police enforcement and road safety benefits, little is known about the organisational factors that assist or hinder the management and operation of RBT. The purpose of this thesis is to explore the perceived barriers and facilitators to the effective operation of RBT in the Queensland Police Service (QPS). Findings will have human resource implications for the QPS and will highlight areas that are currently functioning effectively.-----
Study One involved 22 semi-structured interviews with 36 QPS managers involved in the day-to-day organisation and delivery of RBT operations. Managers were recruited with assistance from members of the QPS's State Traffic Support Branch. The interviews were approximately one hour long and involved exploration of the perceptions of managers involved in the planning and delivery of RBT operations using the concept of organisational alignment to structure the interviews. The results revealed that RBT management activity is facilitated by a range of factors, including: the belief in the importance of RBT; belief that the purpose of RBT has both a deterrent function and a detection function; the increasing use of intelligence to guide RBT strategies; the increasing use of RBT to support other crime reduction strategies; and a genuine desire to improve the current state of affairs. However, a number of apparent barriers to the effective operation of RBT were identified. These included concern about the strategy of the 1.1 testing strategy (i.e. conducting the equivalent of one test per licensed driver per annum), a misunderstanding of the role of general and specific deterrence and a lack of feedback in relation to the success of RBT.-----
The second study involved a questionnaire that was distributed to a random sample of 950 operational police stratified across the regions who are responsible for undertaking RBT on a regular basis. There were 421 questionnaires returned representing a response rate of 44%. Questionnaires were also based on the concepts and constructs of organisational alignment and explored perceptions, beliefs and self- reported behaviour of officers. The results revealed that facilitating factors included a belief in QPS ownership of the RBT program, the agreement that the RBT vision includes road safety goals and apprehension goals, and overall motivation, support and belief in their capability to carry out RBT duties. Barriers included perceived strain related to the 1:1 testing strategy, the lack of feedback in relation to the success of RBT, misunderstanding about the role of deterrence and lack of rewards for participating in RBT duties.-----
The results of both studies have implications for the planning and operation of RBT in the QPS. While the findings revealed that there were many aspects of the RBT program that were currently aligned with best practice guidelines, there are areas of misalignment. In particular, the main areas of misalignment included concern about the strain caused by the current 1:1 testing strategy, a lack of feedback about the success of RBT and a lack of education of the nature and role of deterrence in road safety and RBT operations in particular.
