Differences in ambulance attendances between children with and without an identified history of out-of-home-care.

BACKGROUND: Children in out-of-home-care (OOHC) are a vulnerable population, typically with complex needs, however there is minimal research examining the behavioural presentations that lead to the increased use of acute emergency care by OOHC children. OBJECTIVE: This study aimed to describe differences in lifetime complexity factors identified during ambulance attendances between children with and without an identified history of OOHC. Further, this study aimed to describe whether having an identified history of being in OOHC was associated with increased utilisation of emergency care resources and increased likelihood of multiple ambulance attendances. METHOD: Electronic patient care records from ambulance attendances during the period January 2017 and June 2023 for 27,565 children 0-17 years in Victoria, Australia were examined. RESULTS: Children with an identified history of OOHC had a substantially higher co-occurrence of substance-related harms, violence, self-harm, suicide ideation and attempts, a developmental or intellectual disability and mental health conditions compared with children where there was no identified OOHC history. As hypothesised, logistic regression found, after controlling for all complexity factors, an identified history of OOHC increased likelihood of multiple ambulance attendances (OR = 2.65; 95 % CI: 2.17-3.24, p < .001). CONCLUSIONS: The findings suggest children within OOHC have increasingly complex comorbidities, and this may be associated with increased emergency care utilisation. Development of tailored support to these multiple and complex needs is necessary to help reduce repeated emergency care responses for this at-risk population.

Police-issued barring notices in Western Australia: An analysis of the type, seriousness and trajectory of associated offences.

INTRODUCTION: Police-issued barring notices are currently used in Western Australia in response to alcohol-related disorderly and anti-social behaviour. This paper examines the type, severity and trajectory of the offending behaviours associated with served barring notices. METHOD: WA Police Force de-identified the data for 3815 individuals who had received one or more police-imposed barring notice/s between 2011 and 2020. The offence category associated with each barring notice was examined to explore the overall breakdown and whether/how offending categories change for recipients of subsequent barring notices. RESULTS: For single and multiple barring notice recipients, the most common offence categories were fighting/physical violence and public order offences. Within a subset of the data, non-anti-social offences also spiked. Aggressive behaviours predominate for recipients in metropolitan areas, compared with public order offences in regional locations. DISCUSSION AND CONCLUSIONS: For recipients of multiple barring notices, behaviours do not become more serious but neither do they moderate to any notable extent. The low number of repeat barring notices (5%) may suggest an overall beneficial effect on recipient behaviours but more analysis is needed to examine the potential confounding effects of factors, such as fly-in/fly-out workers, policing and locational differences.

Trends in child and adolescent assault and maltreatment following the re-introduction of the Banned Drinker Register in the Northern Territory, Australia.

OBJECTIVE: In 2017 the Northern Territory (NT) government re-introduced the Banned Drinker Register (BDR) to address the high rates of alcohol related harm. This paper aims to evaluate whether trends in assault, maltreatment and sentinel injuries in children and adolescents were associated with the re-introduction of the BDR, in the context of other local interventions such as police officers stationed in bottle shops being partially removed, Police Auxiliary Liquor Inspectors, and the introduction of a minimum unit price of alcohol. METHOD: Interrupted time series analysis was used to assess monthly trends in emergency department presentations and inpatient hospital admissions for assault, maltreatment and sentinel injuries between January 2014 and December 2019 in the regions of Greater Darwin, Alice Springs, and Katherine. RESULTS: A significant step increase after the introduction of the BDR in emergency department presentations for assault and maltreatment was present when examining the three regions combined (ß = 7.65, 95 % CI = 2.15, 13.16). However, this was not present at the individual community level. Results across a range of other models pointed towards null effects of the BDR introduction. CONCLUSIONS: The current study found that the re-introduction of the BDR had minimal impact on rates of assault, maltreatment, or sentinel injuries in children and adolescents. To ensure long-term harm mitigation from alcohol use, a combination of evidence informed alcohol policies that address the price and availability of alcohol in a comprehensive framework, along with measures which address the underlying social determinants of unregulated drinking and health more broadly will assist in reducing alcohol related harm in both children and adults.

Test purchasing of same day and rapid online alcohol home delivery in two Australian jurisdictions.

OBJECTIVE: With same day online alcohol sales increasing, there is a need to study their regulation. Test purchasing of alcohol home delivery was conducted to measure compliance with regulations for identification checks and unattended deliveries in two Australian jurisdictions (Perth, Western Australia and Geelong, Victoria), which have differing regulations. METHOD: Alcohol orders for same day or rapid (<2 hours) delivery on Friday and Saturday nights were made by research assistants aged 18-24 years in Perth (n=34) and Geelong (n=29). An observation checklist was used to record the delivery interaction, with a specific focus on checking of photo identification at time of delivery and whether deliveries were left unattended. RESULTS: Average time from order to delivery for rapid deliveries was less than one hour in both sites (Perth = 50 minutes; Geelong = 36 minutes). More than 20% of deliveries were made without an identification check in both sites (Perth = 24%; Geelong = 21%). CONCLUSIONS: This pilot study showed alcohol can be delivered to the home within one hour, and not all deliveries include an identification check at point of delivery. These findings indicate a need for policies that empower regulators and police to undertake 'mystery shopper' monitoring to reduce potential harms and improve compliance with alcohol delivery policy.

Adolescent Suicidal Behaviors During the COVID-19 Pandemic in Australia: Analysis of Acute Harms Assessed via Ambulance Data.

PURPOSE: This study investigated changes in suicidal ideation, attempts, and nonsuicidal self-injury (NSSI)-related ambulance attendances among adolescents during the COVID-19 pandemic. METHODS: An interrupted time series analysis using data from the National Ambulance Surveillance System, a globally unique mental health and suicide surveillance system. Patients aged 12-17 years from the state of Victoria, Australia who were attended by ambulance for suicide attempts, suicide ideation, and NSSI between January 2016 and October 2021 were included. Monthly ambulance attendances during the pre-COVID period (January 2016-March 2020) were compared to those in the peak period of COVID-19 (April 2020-October 2021). RESULTS: There were 20,125 ambulance attendances for suicide ideation, suicide attempt, and NSSI in adolescents over the study period. During the pre-COVID period, the number of suicide ideation, attempts, and NSSI attendances was increasing by 1.1% per month (incidence rate ratio [IRR]:1.011; 95% confidence interval [1.009-1.013], p < .001). There was no change in the rate of all suicide ideation, attempt, and NSSI for all adolescents during the period of COVID-19. However, when disaggregated by gender, there was a 0.7% increase in the monthly rate of attendances for females (IRR: 1.007 [1.001-1.013], p = .029), and a 3.0% decrease for males (IRR: 0.970 [0.964-0.975], p < .001). DISCUSSION: Adolescent female suicide ideation, attempt, and NSSI attendances increased during the COVID-19 period, compared with males in the same time period. These findings suggest tailored intervention strategies may be needed to address the increasing trends of self-harm among young people.

Impacts of Northern Territory banned drinker register on police recorded youth assault.

INTRODUCTION: In September 2017 the Northern Territory Government of Australia introduced a banned drinker register (BDR) to mitigate the high levels of alcohol-related harm within the Northern Territory. The current study aimed to examine the impact of the Northern Territory BDR on youth (aged <18 years) using police recorded assault data. METHODS: Interrupted time-series models were used to assess monthly trends in assaults and alcohol-related assaults perpetration and victimisation in the regions of Greater Darwin, Alice Springs and Katherine between January 2014 and December 2019. RESULTS: Examining the three regions combined, after the re-introduction of the BDR a significant step decrease in police recorded youth assault perpetration (ß = -1.67) and a significant step increase in police recorded youth assault victimisation (ß = 1.40) was identified. However, no significant effects were identified at the individual region level. DISCUSSION AND CONCLUSIONS: Findings suggest that restricting alcohol consumption in high-risk adults through the BDR had a limited immediate effect in police recorded youth assaults. Individual level or contextual factors may have influenced both immediate and long-term impacts of the BDR, and as such, future policy design needs to support and empower community leaders across the policy development and implementation process. A wider evaluation of the BDR currently underway may provide additional understanding behind the mechanisms that underpin alcohol-related harm in the Northern Territory.

Police-recorded adult sexual assault in the Northern Territory, Australia: Alcohol involvement and alcohol policy effects.

INTRODUCTION: Between 2017 and 2018 three major alcohol policy changes were introduced in the Northern Territory (NT): the Banned Drinker Register, an individual-level ban enforced via ID scanners at takeaway outlets; a Minimum Unit Price on alcohol; and Police Auxiliary Liquor Inspectors, who monitor takeaway outlets to prevent purchase by people who do not have a legal place to consume alcohol. We aimed to: (i) describe alcohol-involved adult sexual assault in the NT; and (ii) estimate the impacts of these alcohol policies on police-recorded adult sexual assault. METHODS: We used victim records for sexual assault where victims were aged 15 years and over. We undertook descriptive analyses for the NT from 2014 to 2020 and used interrupted time series analysis to assess policy impacts across the NT and in Greater Darwin. RESULTS: In 2020, the NT adult victimisation rate was 105 per 100,000. A large minority (40%) of adult sexual assaults involved alcohol. Interrupted time series analyses showed no effect of the Banned Drinker Register or Minimum Unit Price on sexual assault across the NT or in Greater Darwin. DISCUSSION AND CONCLUSIONS: The rate of adult sexual assaults in the NT is extremely high and many involve alcohol. Neither the Banned Drinker Register or Minimum Unit Price were associated with changes in police-recorded adult sexual assault in Greater Darwin or across the NT. Due to small counts, we were unable to assess policy impacts in three of the four main towns, highlighting the challenges of assessing impacts of policies on sexual assault in small population areas.

Characteristics of high- and low-risk drinkers who use online alcohol home delivery in Western Australia.

INTRODUCTION: Variation in alcohol availability is an important driver of levels of consumption and harm, with recent increases in online alcohol home delivery use expanding availability. There is limited research on the impacts of these changes and the characteristics of consumers who use alcohol home delivery. METHODS: This study presents findings from an online survey (n = 465) of Western Australian adults who had purchased alcohol for home delivery within the past 6 months. Analyses compared high-risk and low-risk drinkers on use of, and exposure to, alcohol home delivery. RESULTS: Compared to low-risk drinkers, high-risk drinkers were significantly more likely to make more frequent online purchases (odds ratio 5.42), utilise same day delivery (odds ratio 2.91) and purchase through specialised online-only retailers (odds ratio 2.69). High-risk drinkers also reported receiving deliveries while intoxicated more often (odds ratio 11.62), and ordering alcohol for delivery to continue a current drinking session (odds ratio 7.47). High-risk drinkers also received advertising for alcohol home delivery more frequently (odds ratio 1.60) than low-risk drinkers. High-risk drinkers also ordered larger quantities of alcohol than low-risk drinkers (M = 49 vs. 32 standard drinks). DISCUSSION AND CONCLUSIONS: Findings from this study indicate that these services are popular with high-risk drinkers and potentially undermine other policy efforts to reduce drinking. Within Australia, stronger legislation (such as mandatory delay between order and delivery) and monitoring (e.g., test purchasing for compliance) are recommended.

The Impact of COVID-19 on Trends of Violence-Related Offences in Australia.

OBJECTIVE: To investigate the medium-term impacts of the COVID-19 pandemic on violence-related offences in Australia, and whether there was evidence of a 'dual pandemic' of family violence in addition to COVID-19. METHODS: Autoregressive Integrated Moving Average time series were conducted to analyse publicly available violent crime statistics data from January 2017 to November 2021. Population rates of homicide, sexual, domestic and non-domestic assault were assessed across each Australian state and territory, with the effects of COVID-19 being modelled using the average monthly World Health Organization COVID-19 stringency rating for each jurisdiction. FINDINGS: All jurisdictions in Australia showed increasing or stable domestic assault trends over the past decade, which were not significantly impacted by COVID-19, nor by the subsequent lockdowns. Non-domestic assaults demonstrated a significant, negative relationship with the stringency index for each jurisdiction, except Western Australia. There was no significant change in the rates of homicide or sexual assault across Australia in relation to COVID-19. CONCLUSION: Overall, there was no evidence of a 'dual pandemic' in Australia, and whilst domestic assaults continue to increase across the country, non-domestic assaults showed a notable but brief decline. However, these have returned to levels at least as high as pre-COVID-19 and some states show a continuing upward trend. The findings also suggest that alcohol availability may have played a role in continuing high violence numbers. Given the ongoing increasing and high levels of family violence in Australia, revised conceptual frameworks and interventions are indicated.

Estimating the impact of the minimum alcohol price on consumers' alcohol expenditure in the Northern Territory, Australia.

OBJECTIVE: From October 2018, the Northern Territory (NT) government introduced a minimum unit price (MUP) for alcohol of $1.30 per standard drink. We assessed industry claims that the MUP penalised all drinkers by examining the alcohol expenditure of drinkers not targeted by the policy. METHODS: Participants recruited by a market research company using phone sampling (n=766, 15% consent fraction) completed a survey in 2019, post-MUP. Participants reported their drinking patterns and their preferred liquor brand. Estimated annual alcohol expenditure for each participant was calculated by collating the cheapest advertised price per standard drink of their preferred brand pre-and-post-MUP. Participants were grouped as consuming within the Australian drinking guidelines ("moderate") or over them ("heavy"). RESULTS: Based on post-MUP drinking patterns, moderate consumers had an average annual alcohol expenditure of AU$327.66 (CIs=325.61, 329.71) pre-MUP, which increased by AU$3.07 (0.94%) post-MUP. Heavy consumers had an estimated average annual alcohol expenditure of AU$2898.82 (CIs=2877.06, 2920.58) pre-MUP, which increased by AU$37.12 (1.28%). CONCLUSIONS: The MUP policy was associated with an increase of AU$3.07 in alcohol annual expenditure for moderate consumers. IMPLICATIONS FOR PUBLIC HEALTH: This article provides evidence that counters the alcohol industry's messaging, enabling an evidence-based discussion in an area dominated by vested interest.

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.

Description of Trends over the Week in Alcohol-Related Ambulance Attendance Data.

Alcohol harms are often determined using a proxy measure based on temporal patterns during the week when harms are most likely to occur. This study utilised coded Australian ambulance data from the Victorian arm of the National Ambulance Surveillance System (NASS) to investigate temporal patterns across the week for alcohol-related ambulance attendances in 2019. These patterns were examined by season, regionality, gender, and age group. We found clear temporal peaks: from Friday 6:00 p.m. to Saturday 3:59 a.m. for both alcohol-involved and alcohol-intoxication-related attendance, from Saturday 6:00 p.m. to Sunday 4:59 a.m. for alcohol-involved attendances, and from Saturday 5:00 p.m. to Sunday 4:49 a.m. for alcohol-intoxication-related attendances. However, these temporal trends varied across age groups. Additionally, hours during Thursday and Sunday evenings also demonstrated peaks in attendances. There were no substantive differences between genders. Younger age groups (18-24 and 25-29 years) had a peak of alcohol-related attendances from 7:00 p.m. to 7:59 a.m. on Friday and Saturday nights, whereas the peak in attendances for 50-59 and 60+ years was from 5:00 p.m. to 2:59 a.m. on Friday and Saturday nights. These findings further the understanding of the impacts of alcohol during different times throughout the week, which can guide targeted policy responses regarding alcohol use and health service capacity planning.

Do patron bans affect subsequent behaviour? An examination of pre- and post-ban offending for barring notice and prohibition order recipients in Western Australia.

INTRODUCTION: To explore whether receipt of either of two patron banning provisions currently used in Western Australia-in response to alcohol-related disorderly and anti-social behaviour-is associated with changes to subsequent offending. METHOD: Western Australia Police de-identified the offender records and associated data for 3440 individuals who had received one or more police-imposed barring notice/s between 2011 and 2020, and 319 individuals who had received one or more prohibition orders between 2013 and 2020. The number of offences recorded for each recipient before and after the first notice/order were examined to understand the potential effect of both provisions upon subsequent offending. RESULTS: The low number of repeat barring notices (5% of the total) and prohibition orders (1% of the total) points to their general success. Analysis of offending records before and after receipt/expiry of either provision indicates that both have a generally positive effect on subsequent behaviours. For all barring notice recipients, 52% recorded no further offences and for all prohibition order recipients, 58% recorded no further offences. There was a less positive effect for the sub-set of multiple ban recipients and prolific offenders. DISCUSSION AND CONCLUSIONS: Barring notices and prohibition orders appear to have a generally positive effect on subsequent behaviours for the majority of recipients. More targeted interventions are recommended for repeat offenders, for whom patron banning provisions have a more limited effect.

Key informant perspectives on 3 am last drinks legislation in Queensland, Australia.

INTRODUCTION: The objective of this study was to explore key informant attitudes towards the 'Last Drinks at 3am' legislation in Safe Night Precincts in Queensland, Australia. METHOD: Sixty-six interviews were conducted with a range of stakeholders including licensees, law enforcement and frontline health professionals. Interviews were semi-structured and analysed using thematic analysis. Key informants responded to questions regarding their experiences of, and opinions about, the last drinks legislation. RESULTS: Key informants reported a range of experiences around the impact of last drinks restrictions, including reduced staffing costs and patron-related problems within licensed venues. While some venues reported that their businesses lost money, others reported no change in income or that they changed their business model to compensate. Law enforcement and health professionals reported a range of benefits including reduced alcohol-related anti-social behaviour, drunkenness and injury. CONCLUSIONS: The majority of key informants reported that the last drinks legislation reduced harm, while having minimal detrimental impact on business.

Impact of alcohol policy changes on substance-affected patients attending an emergency department in the Northern Territory with police.

OBJECTIVE: Assess the impact of Northern Territory alcohol policy changes to ED utilisation at Royal Darwin-Palmerston Regional Hospitals. METHODS: Interrupted time series analysis explored trends in monthly ED attendance numbers and the proportion self-discharging prior to policy changes (September 2016 to August 2017) and after three sequential interventions; the Banned Drinker Register, introduced September 2017, system changes to the sobering shelter, January 2018, and the minimum unit floor price (MUFP), October 2018. A targeted cohort of attendances transported by police as an alternative to the sobering shelter or police watch-house when there is a medical concern was selected as they are likely impacted by all policy changes. RESULTS: Police transported 1176 patients on 2070 occasions from September 2016 to March 2019. There was a downward trend in monthly attendances across the study period, with no significant change attributable to the Banned Drinker Register, a significant step decrease with the sobering shelter changes (P = 0.002), and a significant gradual decrease following the MUFP (P = 0.025). This represented an immediate decrease of 3.82 attendances per month/10 000 residents following the sobering shelter changes and a gradual decrease of 0.92 attendances/10 000 residents after the MUFP. Rates of self-discharge were high, 45% in the pre-intervention phase, decreasing to 28% following the MUFP but this trend did not reach significance with any intervention. CONCLUSION: The sequential introduction of broad sweeping alcohol policy changes introduced by the Northern Territory government was associated with significant reductions in ED utilisation. The proximity of the introduction of interventions creates difficulties identifying individual policy influence.

Factors Associated with Unwanted Sexual Attention in Australian Nightlife Districts: An Exploratory Study of Nightlife Attendees.

BACKGROUND: Experiences of unwanted sexual attention (UWSA) are commonplace within nightlife environments. While typically associated with aggression perpetration, literature has suggested that a history of childhood corporal punishment (CCP) may also be related to experiences of victimisation in nightlife environments. The current exploratory study aims to examine the associations between experiences of UWSA victimisation and a history of CCP, trait aggression, and conformity to masculine norms (Playboy and Winning), for males and females separately. METHOD: Street intercept interviews in the Brisbane inner-city entertainment precincts were used to measure demographic details and participants' breath alcohol concentration. Online follow-up surveys were used to record participants' experiences of UWSA on the night of interview, history of CCP, and self-reported rates of trait aggression and conformity to masculine norms. The final sample consisted of 288 females, as there were not sufficient male UWSA experiences for analysis. RESULTS: Approximately 20% of female nightlife patrons experienced some form of UWSA victimisation. Logistic regression analyses identified that after controlling for age and intoxication, a history of CCP, trait aggression and masculine norm conformity were unrelated to experiences of UWSA for female respondents. CONCLUSIONS: The current study found that individual factors were unrelated to experiences of UWSA, indicating that simply being in the nightlife environment, especially as a female, increases the risk of UWSA victimisation. Understanding and exploring social and environmental risk factors, rather than individual factors, is needed to prevent victimisation in nightlife environments.

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.

A systematic narrative review of the effects of alcohol supply reduction policies on children and adolescents.

BACKGROUND: Children are often exposed to increased rates of secondary harm such as physical harm, motor vehicle incidents, maltreatment, and neglect because of others' or their own alcohol consumption. Alcohol supply reduction, or alcohol control policies, are often enacted to mitigate alcohol harms within the community. The current systematic narrative review aims to synthesise recent literature that examines how alcohol supply reduction policies impact the physical health, mental health, and offending behaviour of children and adolescents. METHODS: Eight databases and grey literature sources were systematically searched, and results were synthesised by policy under evaluation. Twenty-one peer reviewed articles and ten grey literature articles were included after screening of 7,135 original articles. Included articles examined the alcohol control policies of the minimum legal drinking age, price control, and trading restrictions, with the most common outcomes under evaluation being related to the physical health or offending behaviour of adolescents. RESULTS: Overall, the current review identified that the impact of alcohol policy on children and adolescents varied depending on the policy type, policy environment and assessed outcome. Common limitations within the literature include inability to control for covariates, use of alcohol related outcomes unsuitable to children and adolescents, and use of cross-sectional data and regression-discontinuity analysis in lieu of actual policy changes. CONCLUSIONS: The current review highlights the need to further evaluate the impact of actual alcohol-related policy changes on children and adolescents.

The association of childhood physical abuse, masculinity, intoxication, trait aggression with victimization in nightlife districts.

BACKGROUND: High-risk intoxication, trait aggression and conformity to masculine norms are associated with increased risk of barroom aggression; however, less is understood regarding the factors associated with victimization in the night-time environment. OBJECTIVE: This study aimed to explore the influence of childhood physical abuse, high-risk intoxication, conformity to masculine norms and trait aggression on physical and/or verbal victimization in the night-time environment. PARTICIPANTS AND SETTING: A sample of N = 490 patrons aged 18-50 years (M = 23.02, SD = 5.89, 58.8% female) were recruited in Fortitude Valley and West End district, Queensland. METHOD: Participants completed a street interview, including breathalyser, and a follow-up online survey asking about experiences of aggression on the night of interview, experiences of childhood physical abuse and psychosocial correlates. RESULTS: For males, but not females, childhood physical abuse (OR = 3.98) increased the risk of physical and/or verbal victimization. Conformity to the masculine norm of Winning (OR = 0.21) was protective against physical and/or verbal victimization for males, and trait aggression (OR = 1.51) was significantly associated with increased risk of physical and/or verbal victimization for females. CONCLUSIONS: These findings add to the growing literature surrounding the long-term impacts of childhood physical abuse, demonstrating experiences of childhood physical abuse are significantly associated with victimization in the night-time economy. The current findings should be taken into consideration when constructing public policy or directed interventions, to help reduce aggression and violence in the night-time economy.

A systematic mapping review of interventions to improve adolescent mental health literacy, attitudes and behaviours.

AIM: The onset of mental illness is most common in adolescence, therefore mental health promotion efforts frequently target this age group. Evaluation literature in this area is largely segmented into specific domains in terms of settings, countries, and/or groups of young people, but an overall understanding and comparison across these areas is lacking. The current review aims to provide such an overview of interventions/programs which attempt to improve adolescents' mental health literacy, attitudes/stigma and behaviours. METHODS: A systematic mapping review synthesized the strengths and weaknesses of published interventions/programs to improve mental health outcomes in youth. Ten databases and grey literature sources were searched, and results were categorized according to sample, location/setting, type of information presented, delivery and testing procedures, mental health outcome/s evaluated, and limitations. RESULTS: One hundred and forty articles met the inclusion criteria; 126 were original records and 14 were reviews. Mental health literacy and attitudes/stigma were examined most frequently, and studies were predominantly conducted in school-based environments and high income economies. Intervention/program effectiveness varied across outcome/s measured, setting, and control group usage, with mental health literacy exhibiting the most positive changes overall. Common limitations included no long-term follow up or control group inclusion. CONCLUSIONS: Despite generally positive changes seen throughout studies in this area, effectiveness differed across a range of methodological domains. Most research is conducted in schools and higher income economies, but the lack of investigation in other contexts (i.e., internet or community) or lower income countries suggests our understanding in this area is constrained.
