The Impact of Minimum Unit Price on Police-Recorded Alcohol-Related Assault Rates in the Northern Territory, Australia.

OBJECTIVE: From October 1, 2018, the Northern Territory (NT) of Australia introduced a minimum unit price (MUP) for alcohol of AU$1.30 per standard drink. The MUP was introduced to address the high alcohol consumption rates and harms within the NT. This study aimed to investigate the unique short-term impact of the MUP on alcohol-related assaults across the NT, for the NT overall and separately for four key regions (Darwin and Palmerston, Alice Springs, Katherine, and Tennant Creek); which allowed for the consideration of differences in concurrent alcohol interventions and population (e.g., Alice Springs had Police Auxiliary Liquor Inspectors (PALIs) introduced on October 1, 2018, whereas Darwin and Palmerston only had the MUP introduced in this period). PALIs effectively equate to a police officer being stationed in every off-premise liquor vendor. METHOD: Using data from January 2013 to September 2019, interrupted time series (ITS) analyses assessed the short-term impact of the MUP on the monthly rate of police-recorded alcohol-related assaults. RESULTS: A 14% reduction (B = -3.07 [-5.40, -0.74], p < .010) was found for alcohol-related assault offenses per 10,000 in Darwin/Palmerston. Significant reductions were also noted in Alice Springs and the NT overall, although PALIs are likely to have contributed to these reductions in addition to the MUP. CONCLUSIONS: This short-term impact warrants longer-term follow-up to determine whether the reductions in alcohol-related assaults following the introduction of MUP are maintained, and the extent to which assault rates are influenced by other alcohol-policy interventions in the NT.

How Policy Influences Aggression in Nightlife Spaces: A Proposed Core Aggression Cycle.

OBJECTIVE: This theoretical review examines prior theories that aim to explain the disproportionate amount of violence in Nighttime Entertainment Precincts (NEPs) and proposes a comprehensive model that links violence to policy and environmental changes. METHOD: To understand why this violence occurs and better inform prevention and intervention, a theoretical review using a "people" in "places" approach was conducted. This perspective considers the precursors of violence both at the individual level and among a group within a shared environment. RESULTS: Prior public health, criminology, and economic theories that aim to explain why violence occurs in NEPs provide a limited perspective, each only capturing part of the story. Further, prior theories fall short of demonstrating how policy and environmental changes in an NEP can influence the psychological determinants of aggression. When unified in a social-ecological framework, they can provide a more holistic explanation of violence in NEPs. We propose the Core Aggression Cycle (CAC) model, which draws from the prior theories examining violence in NEPs, and psychological theories of aggression. The CAC model is a proposed basis for unifying future research across disciplinary discourses. CONCLUSIONS: The CAC provides a clear conceptual framework that has the capacity to incorporate multiple previous and future theoretical perspectives on how alcohol policy and the environment influence violence within nightlife spaces. The CAC can be used by policy makers to establish new policy, critically evaluate existing policy, and determine whether policy adequately addresses the underlying mechanisms that produce violence in NEPs.

Learning from alcohol (policy) reforms in the Northern Territory (LEARNT): protocol for a mixed-methods study examining the impacts of the banned drinker register.

INTRODUCTION: The Banned Drinker Register (BDR) was reintroduced in the Northern Territory (NT) in September 2017. The BDR is a supply reduction measure and involves placing people who consume alcohol at harmful levels on a register prohibiting the purchase, possession and consumption of alcohol. The current study aims to evaluate the impacts of the reintroduction of the BDR, in the context of other major alcohol policy initiatives introduced across the NT such as Police Auxiliary Liquor Inspectors and a minimum unit price for alcohol of US$1.30 per standard drink. METHODS AND ANALYSES: The Learning from Alcohol (policy) Reforms in the Northern Territory project will use a mixed-methods approach and contain four major components: epidemiological analysis of trends over time (outcomes include health, justice and social welfare data); individual-level data linkage including those on the BDR (outcomes include health and justice data); qualitative interviews with key stakeholders in the NT (n≥50); and qualitative interviews among people who are, or were previously, on the BDR, as well as the families and communities connected to those on the BDR (n=150). The impacts of the BDR on epidemiological data will be examined using time series analysis. Linked data will use generalised mixed models to analyse the relationship between outcomes and exposures, utilising appropriate distributions. Qualitative data will be analysed using thematic analysis. ETHICS AND DISSEMINATION: Ethics approvals have been obtained from NT Department of Health and Menzies School of Health Research Human Research Ethics Committee (HREC), Central Australia HREC and Deakin University HREC. In addition to peer-reviewed publications, we will report our findings to key organisational, policy, government and community stakeholders via conferences, briefings and lay summaries.

Alcohol-Involved Family and Domestic Violence Reported to Police in Australia.

Family and domestic violence (FDV) is a significant social issue that causes major harm across Australia. Alcohol has been identified as a contributing factor to FDV, and as such increased understanding of the role of alcohol in police-reported FDV incidents may provide the basis for developing specific clinical and forensic approaches. This study aims to identify the key correlates of alcohol-related FDV within police-reported FDV incidence. Data sourced from several states and territories across Australia were used to profile demographic and personal factors involved in police-reported FDV incidents, and to identify the types of incidents involving alcohol. For each state, three separate binary regressions were conducted for family violence, intimate partner violence, and FDV incidents in which alcohol was involved. Between 24% and 54% of FDV incidents reported to police were classified as alcohol-related. Although there appeared to be an association between relative socioeconomic disadvantage and an incident being alcohol-related, this association varied across states. Where victim and offender data were available, offenders were significantly more likely to be alcohol-affected than victims. Alcohol-related FDV incidents were also twice as likely to involve severe physical violence including injuries that were life threatening, as well as an increased likelihood of recidivism. This study demonstrates that alcohol plays a substantial role in police-reported FDV across Australia. It also demonstrates that other factors such as drug use, breach of orders, and repeat offending are associated with alcohol involvement across family violence and intimate partner violence.

Coercive Controlling Behaviors and Reporting Physical Intimate Partner Violence in Australian Women: An Exploration.

This study explores two approaches to measuring coercive controlling behaviors (CCBs)-counting how many different CCB types and examining the frequency of each CCB experienced-to examine their utility in explaining the relationship between CCBs and physical intimate partner violence (IPV). Australian women aged 18-68 years (n = 739; Mage = 31.58, SDage = 11.76) completed an online survey. Count and frequency CCB approaches yielded similar significant associations with increased physical IPV. Both approaches suggest that frightening behaviors in particular are significantly indicative of also experiencing physical IPV; however, when you count CCB types, public name-calling becomes important, whereas when you examine the frequency of each CCB type, jealousy/possessiveness becomes important. These findings suggest differential utility between measures of CCBs, which examine the frequency of specific CCB types and which count CCB types, and that both approaches are useful in understanding how coercion and control relate to physical violence within intimate relationships.

Queensland Alcohol-related violence and Night-time Economy Monitoring (QUANTEM): Rationale and overview.

This commentary introduces the special section on the outcomes of the Queensland Alcohol-related violence and Night-time Economy Monitoring project and outlines the political and policy context of the interventions put in place under the Queensland government's Tackling Alcohol-Fuelled Violence strategy. The development of the strategy was informed by alcohol policy initiatives trialled in other major Australian cities over the past two decades. The articles in this special section examine the impact of the Tackling Alcohol-Fuelled Violence policy stages on alcohol-related harms and local economies across selected entertainment precincts (Safe Night Precincts). A rich array of data were utilised, including administrative health and justice data, data reflective of nightlife trading (i.e. foot traffic data, ID scanner data and live music performances) and street surveys. Findings have implications for research, policy and practice and demonstrate the need for comprehensive evaluations that can accommodate the complexities of modern alcohol policy in Australia.

The impact of Queensland's Tackling Alcohol-Fuelled Violence Policy on nightlife and business trade.

INTRODUCTION: Key elements of the Queensland Government's Tackling Alcohol Fuelled Violence (TAFV) policy included the introduction of mandatory identification (ID) scanners and reduced trading hours for licensed venues located within Safe Night Precincts (SNP). These measures raised concerns among licensed venue owners and other key stakeholders regarding the potential negative impact of the policy on business trade and nightlife. Using multiple data sources, this paper examines the impact of the TAFV policy on nightlife and trade in three Queensland SNPs: Fortitude Valley, Surfers Paradise and Cairns. METHODS: Data from ID scanners (2017-2019), foot traffic counters (2017-2019) and counts of liquor licences issued (2015-2019) were used to measure the policy's impact on the number of patrons and licensed venues within SNPs. Joinpoint regression and auto-regressive integrated moving average models were developed to examine changes in these measures over time. RESULTS: No significant changes were observed in the number of ID scans over time, although Surfers Paradise showed a 0.13% reduction during high alcohol hours. Foot traffic counts from Fortitude Valley showed no significant impact of the policy on the number of patrons in the area during high-alcohol hours. The number of commercial hotel licenses increased in all three regions, and commercial other-bar licenses increased in all regions except Surfers Paradise SNP where numbers remained stable. DISCUSSION AND CONCLUSIONS: Patterns in trading and the number of patrons within SNPs were mostly stable or increasing following the implementation of the TAFV policy beyond normal fluctuations.

Summarising the impacts of the Queensland Alcohol-related violence and Night-Time Economy (QUANTEM) project.

This closing commentary to the special section presents an overview of the Queensland Alcohol-related violence and Night-Time Economy Monitoring evaluation findings in comparison to those from other jurisdictions where similar interventions have been implemented (such as Sydney and Newcastle), and especially with previous studies that have used similar evaluation methodologies, such as the Dealing with Alcohol and the Night-Time Economy study. Overall, the articles documented promising reductions in alcohol-related harm, building on the existing evidence base for multi-pronged interventions in entertainment districts. Importantly, this is the first comprehensive investigation to also look at impacts on nightlife-related business and findings demonstrated, that there were improvements for many businesses. There are substantial policy implications for Queensland and other jurisdictions (nationally and globally) wanting to reduce late night alcohol-related harm in entertainment districts.

The impact of changes to alcohol policy on patron drinking behaviours in Queensland.

INTRODUCTION: On 1 July 2016, stage 1 of the Tackling Alcohol-Fuelled Violence (TAFV) policy was introduced in Queensland, Australia and included restricted alcohol service to 03:00 in dedicated entertainment precincts (safe night precincts or SNPs). During stage 2 (from 1 February 2017), the number of extended trading permits (i.e. trading until 05:00) per venue were reduced; and during stage 3 (from 1 July 2017), networked identification scanners were mandated for late-night venues. We aim to examine whether patron drinking behaviours in two key SNPs changed significantly following stages 2 and 3. METHODS: The study design was repeated cross-sectional, with three data collection (policy) stages. Patrons street surveys were conducted in Fortitude Valley (n = 2066) and Cairns (n = 1021) SNPs between July 2016 and November 2018. Linear or negative binomial regressions were conducted to examine changes in three key outcomes: blood alcohol concentration (BAC) reading, proportion of pre-drinkers and number of pre-drinks. RESULTS: We found no significant difference in BAC reading, proportion of pre-drinkers or number of pre-drinks at stages 2 and 3 of the policy compared to baseline in Fortitude Valley. In Cairns, we found significant reductions in patron BAC at stage 3 of the policy, and female BAC at stages 2 and 3 compared to baseline; while the proportion of females pre-drinking significantly reduced by half in stage 2. DISCUSSION AND CONCLUSIONS: Despite evidence of some reductions in alcohol consumption, high levels of intoxication remain, suggesting harm reduction may be more difficult to achieve in these drinkers.

The impact of late-night alcohol restrictions on ambulance call-outs in entertainment precincts.

INTRODUCTION: In July 2016, the Queensland Government introduced the Tackling Alcohol-Fuelled Violence (TAFV) policy to address alcohol-related harm in entertainment precincts [safe night precincts (SNP)]. Additional measures were introduced in February and July 2017. We aim to examine the impact of the policy on Queensland Ambulance Service call-outs in Fortitude Valley, Surfers Paradise, all 15 SNP suburbs combined and statewide. METHODS: Auto-regressive integrated moving average (ARIMA) models and seasonal ARIMA (SARIMA) models were developed to test the impact of TAFV policy stages on monthly number of ambulance call-outs during high alcohol hours (HAH; Friday and Saturday nights, 20:00-05:59) over an 8-year period (July 2011-June 2019). RESULTS: The average number of monthly call-outs in HAH reduced by 26.2% in Fortitude Valley, 21.1% in Surfers Paradise and 4.3% in all 15 SNP suburbs combined. In Fortitude Valley, there was a significant decline in the monthly number of call-outs between 00:00 and 02:59 and across all HAH combined when examining the cumulative effect of the policy stages; and significant declines between 03:00 and 05:59 after each stage and cumulatively. Across the 15 SNP suburbs combined, there was a significant decline in call-outs between 03:00 and 05:59 after the third policy stage (July 2017). There were no significant declines in Surfers Paradise or statewide. DISCUSSION AND CONCLUSIONS: Overall, the introduction of the TAFV policy stages in Queensland had a limited effect on ambulance call-outs during HAH. However, there were some notable declines in HAH ambulance call-outs in some of the state's key nightlife suburbs.

The combined impact of higher-risk on-license venue outlet density and trading hours on serious assaults in night-time entertainment precincts.

BACKGROUND: Night-time entertainment precincts (NEPs) are clusters of higher-risk on-licence venues, that pose a significant burden on health and social order services. Outlet density and trading hours are two of the most well researched contributors to alcohol availability within NEPs; increases in outlet density and late-night trading hours within NEPs have been independently associated with increased assaults. This is the first study to examine both factors across cities to predict alcohol-related assaults. METHODS: Licensing data were used to investigate the effect of outlet density and trading hours on police recorded serious assaults in nine NEPs (9 cross-sectional units) across Queensland from January 2010 to July 2018 at monthly intervals (102 longitudinal units). Multi-level models were used to determine i) whether precinct-level trading hours moderated the relationship between outlet density and serious assaults; and ii) the impact of outlets closing before 12am, 3am, and 5am on serious assaults. FINDINGS: The positive relationship between outlet density and assaults was stronger in precincts with trading hours ending at 5am compared to 3am (IRR = 1.01, p = 0.03). The amount of venues closing before 12am was associated with reduced numbers of assaults (IRR = 0.97, p = 0.04), while venues closing between 12:01am-3am and 3:01am-5am were associated with increased assaults (IRR = 1.02, p<0.01; IRR = 1.01, p = 0.02). CONCLUSIONS: Late night service of alcohol creates more harm in areas of high outlet density, whereas early closing venues in areas where outlet density is low is associated with reduced number of assaults. This relationship should be taken into account in the development of future alcohol policies.

The Role of Illicit Drug Use in Family and Domestic Violence in Australia.

Drug use has been shown to interact in complex ways with the occurrence and prevalence of family and domestic violence (FDV), with illicit drug use being associated with an increased risk for FDV. The current study aims to extend upon the literature by investigating the role of illicit drugs in intimate partner violence (IPV), family violence (FV), and other violence (violence between people other than partners or family) within a representative Australian sample (n = 5,118). Participants were recruited through an online survey panel and completed an online self-report survey assessing the role of alcohol and other drugs on violence, with a specific focus on FDV. Binary logistic regression showed that respondents who reported having used any illicit drug in the past 12 months (with or without alcohol use) had over three times the odds of experiencing any violence in the past 12 months (OR = 3.18, 95% confidence interval (CI) = [2.25, 4.48]) compared with those not using illicit drugs. Furthermore, drug involvement in FDV (IPV or FV) was significantly more likely than other violent incident types (OR = 1.65, 95% CI = [1.25, 2.19]). For the most recent FDV incident, age group was the only significant demographic predictor of drug involvement at this incident; younger age groups were over twice as likely to report drug involvement than those over 65 years of age. Drug involvement at the most recent FDV incident was also associated with over twice the odds of injury (OR = 2.38, 95% CI = [1.67, 3.38]) and significantly greater negative life impact. The findings that drug use increases both the risk for and impact of FDV indicate the need for policy that advocates for interventions addressing both drug use and violence in combination.

Situational Characteristics Uniquely Associated With Children's Exposure to Intimate Partner Violence.

Exposure to parental violence can have devastating consequences for children, including significant personal, social, and academic problems. The present study determined the situational factors that are associated with children's exposure to intimate partner violence (IPV) incidents. To examine whether these factors were unique to child witnesses' presence at IPV incidents, we also determined the factors that are associated with children's exposure to family violence (FV) and other family member witnesses' exposure to IPV incidents. Participants responded to an online panel survey investigating the role of alcohol and other drugs in family and domestic violence incidents in Australia. Nine hundred fifty-two respondents reported an IPV incident and 299 reported an FV incident; they provided details about their most recent incident. Results showed that child witnesses were more likely to be present during IPV incidents if the incident took place at home (odds ratio [OR] = 3.10), if a similar incident had occurred previously (OR = 1.66), if drugs were involved (OR = 1.60), and if a police report was made (OR = 2.61). There was some overlap with the other witness and violence combinations: The presence of a police report also predicted child witnesses' presence at FV incidents, and a home location also predicted other family member witnesses' presence at IPV incidents. These results enhance our understanding of the situations in which children might witness IPV incidents; future research is needed to determine whether these situational factors can be used to judge risk.

The prospective impact of 10-day patron bans on crime in Queensland's largest entertainment precincts.

INTRODUCTION: Night-time entertainment precincts (NEP) are the site of a disproportionate amount of alcohol-related violence, injuries and anti-social behaviour. To combat this the Queensland government introduced patron bans in October 2014, giving police the power to exclude individuals from NEPs and preventing patrons from remaining in or entering the designated area or from designated premises for the ban duration. Mandatory identification scanners within licensed venues were also introduced, which are used to enforce patron bans. This study aimed to evaluate the effectiveness of police-issued 10-day patron bans for preventing alcohol-related violence or anti-social behaviour occurring within NEPs during high-alcohol hours. METHODS: Queensland's largest NEPs; Brisbane central business district, Fortitude Valley and Surfers Paradise central business district; were examined. Time-series autoregressive integrated moving average analyses were used to estimate the influence of 10-day patron bans on police-recorded serious assaults, common assaults and good order offences. Analyses controlled for the introduction of relevant policy and identification scanners. RESULTS: The number of police-issued patron bans did not significantly predict changes in serious assault, common assault or good order offence trends the weekend following the ban (within the 10-day period). DISCUSSION AND CONCLUSIONS: The current study was unable to find evidence indicating that 10-day patron bans reduced alcohol-related harms experienced in Queensland's largest NEPs in the short term. Further research needs to be conducted examining other types of patron bans, particularly longer bans issued in other jurisdictions or by licensees, and whether bans change individual's behaviour.

The impact of street service care on frontline service utilisation during high-alcohol use hours in one night-time entertainment precinct in Australia.

INTRODUCTION AND AIMS: Street service care providers in Queensland, Australia are organisations tasked with assisting vulnerable individuals and aiding intoxicated patrons that are at risk of harm in night-time entertainment precincts (NEP). Members of these organisations patrol NEPs and provide services, such as first aid, to individuals in need. There has been no research conducted on their impact on crime, injuries and on the duties of Australian frontline service resources (e.g. police and ambulance services). This study evaluated the introduction of a single street service care in the Cairns NEP on police-recorded assaults, emergency department injury presentations and ambulance service utilisation during high-alcohol hours. DESIGN AND METHODS: Police-recorded assaults (common and serious), emergency department injury presentations and ambulance attendances for the Cairns suburbs were examined. Autoregressive integrated moving average time series analyses were used to determine the impact of street service care on monthly counts for each dataset. RESULTS: Serious assaults during high-alcohol hours significantly declined after the introduction of the support service in Cairns, with a one-month lagged impact (B = -1.66, 95% confidence interval -3.02, -0.30). No other significant impact on common assaults, emergency department injury presentations or ambulance attendances were found. DISCUSSION AND CONCLUSIONS: This study provides preliminary evidence that street service care may help to decrease assaults within a single NEP. However, further research investigating the impact of street services in larger cities, and determining what other roles the service may be able to play in preventing alcohol-related harm, is needed.

Aggression and violence at ambulance attendances where alcohol, illicit and/or pharmaceutical drugs were recorded: A 5-year study of ambulance records in Victoria, Australia.

BACKGROUND: This study describes the frequency and characteristics of aggression and/or violence in ambulance attendances involving alcohol, illicit and/or pharmaceutical drug use in Victoria, Australia between January 2012 and January 2017. METHODS: Patient characteristics, context, and substance use involvement in ambulance attendances were examined to determine associations with attendances where aggression and/or violence was recorded. RESULTS: There were 205,178 ambulance attendances where use of alcohol, pharmaceutical drugs or illicit substances contributed to the reason for the attendance. Paramedics recorded acts of aggression and/or violence in 11,813 (5.76 %) of these attendances. Aggression/violence was more likely to be recorded in certain contexts. Compared with attendances where aggression/violence was not recorded, attendances where aggression/violence was recorded were significantly more likely to involve younger and male patients, and occur on Friday and Saturday nights. Alcohol intoxication was involved in more than half of attendances where aggression/violence was recorded, and was almost twice as prevalent as those involving illicit drug use where aggression/violence was recorded. This pattern was consistent across all hours, high-alcohol hours only, by metropolitan/regional location, and by police co-attendance. CONCLUSIONS: Aggression and violence are frequently recorded in ambulance attendances involving alcohol, pharmaceutical drugs or illicit substances, and, most often involve alcohol. This violence poses a recurring threat to the health and safety of paramedics, bystanders, and patients. Greater priority should be given to reducing alcohol-related violence through evidence-based policy measures targeting high-risk groups (e.g. young adult males) and contexts (e.g. weekends, late at night) where harm is most likely to occur.

The Impact of Liquor Restrictions on Serious Assaults across Queensland, Australia.

Aims: This study aimed to explore the relationship between a 00:00 liquor restriction, introduced on 1 July 2016, and alcohol-related harm by examining its impact on serious assault numbers during high-alcohol hours (20:00-6:00 Friday and Saturday night), from 1 January 2009 to 30 June 2018. Methods: Two types of locations only impacted by the liquor restriction were identified: designated safe night precincts (SNPs) and other local government areas (LGAs). A times series autoregressive integrated moving average analysis was used to estimate the influence of liquor restrictions on police-recorded serious assaults in the two years following the policy introduction, for SNPs and LGAs separately. Results: Contrarily to our predictions, monthly police-recorded serious assaults did not significantly change within SNPs or LGAs following the introduction of liquor restrictions. Conclusion: The implementation of the Queensland liquor restriction did not result in a clear, unique reduction in serious assault trends. Further investigation should consider the impact of liquor restrictions in conjunction with other policy changes as public perception of restrictions and their cumulative impact may produce varied outcomes.

The Impact of Twenty Four-Hour Public Transport in Melbourne, Australia: An Evaluation of Alcohol-Related Harms.

OBJECTIVE: Transporting people out of nightlife districts is often cited as a major issue associated with alcohol-related harm. The Victorian Government introduced 24-hour public transport (24hr PT) in Melbourne, Australia, on Friday and Saturday nights in January 2016. After the 1-year trial period, funding was extended for a further 4 years, at a cost of more than AU$300 million to date. The current study aimed to determine whether 24hr PT reduced harms associated with the nightlife of Melbourne and whether there has been an increased number of people using the transport and visiting Melbourne city on Friday and Saturday nights. METHOD: Police assault data, ambulance attendance data, crash data, public transport use data, and pedestrian counting data were analyzed to determine the impact of 24hr PT on harms in the nightlife of Melbourne, as well as changes in the number of people using public transport and attending the city. RESULTS: There was no change from 2015 to 2016 in the number of police-recorded assaults, ambulance attendances, or crashes for the entirety of the night. There were significantly more people out in the city later in the evening, and more people using trains and trams during the 24hr PT time (i.e., 1 A.M.-5 A.M.). CONCLUSIONS: The initiative did not decrease harm in Melbourne nightlife, in contrast to industry, government, and expert predictions. With expenditures of more than AU$300 million, the costs and benefits of this initiative require further consideration and research, especially when it is proposed in opposition to evidence-based solutions, such as closing venues earlier.

Alcohol use in family, domestic and other violence: Findings from a cross-sectional survey of the Australian population.

INTRODUCTION AND AIMS: The link between alcohol and experience of violence is well-documented, but there is a paucity of empirical research on the role of alcohol specifically in family and domestic violence (FDV) in Australia. The aim of the current study was to describe the relationship between alcohol use and FDV in the Australian population, and to examine key differences between three different types of violence: family violence, intimate partner violence (IPV) and other violence. DESIGN AND METHODS: An online panel survey was conducted using a stratified random sampling design. RESULTS: In total, 5118 respondents were included, of whom 44.5% reported experiencing violence in their lifetime, and 6.0% reported recent (past year) experience of violence. Recent violent incidents were comprised of IPV (41.8%), family violence (13.1%) and other violence (45.1%). Approximately one-third of all violent incidents experienced (either as a victim or perpetrator) were alcohol-related, and 37.8% of respondents who experienced IPV and 27.8% of those who experienced family violence reported past year heavy-episodic drinking. Alcohol use was associated with higher rates of physical violence and injury at IPV incidents. Alcohol consumed at IPV incidents was most often purchased from a supermarket liquor store (37.0%) and consumed at the respondent's home, regardless of the distance between the purchase location and incident location. DISCUSSIONS AND CONCLUSIONS: This study found that alcohol is frequently involved in FDV incidents, particularly IPV. Alcohol use was associated with a higher chance of physical violence and of injury at IPV incidents.

Investigating and validating methods of monitoring foot-traffic in night-time entertainment precincts in Australia.

BACKGROUND: Assaults occur frequently in night-time entertainment precincts (NEPs), with rates typically reported using estimated resident population. However, this form of reporting does not accurately represent the number of people within the NEP at the time of an assault or potential fluctuations in density throughout the course of the night. As such, the aim of this study was to assess multiple methods of obtaining an accurate estimate of hourly foot-traffic within NEPs. METHODS: The validity and reliability of three types of foot traffic counters were assessed. A passive-infrared sensor and two different types of smartphone sensor were installed at two sites in Australia from 2016 to 2018, ongoing (pilot phase: 2016-2017; validation phase: 2018). Researchers also manually counted the number of people walking past through the range of two of these sensors across the course of Friday, Saturday and Sunday nights between 8 pm to 2am. RESULTS: Results show a similar trend between the smartphone counts, the sensor counts, and the manual counts; however there was notable variability (43%-267% compared with manual counts). Analysis showed that all measures were significantly positively correlated. CONCLUSION: Reliable counting of the number of people attending nightlife precincts is an important element of ongoing studies into nightlife settings and associated rates of harm. There are multiple methods of estimating fluctuations in foot traffic within a NEP, however, determining the most appropriate method to use requires consideration of the proximity of pathways in the area, budget constraints, and project aims. Of the methods tested, laptop WiFi traffic monitoring programs functioned the least consistently. Specifically designed smartphone sensors overcame this issue; however, they required dedicated power sources. The current study found infrared scanners appeared to be the most accurate across sites; additionally they functioned consistently, and were the simplest method to setup and maintain.
