Abstract: Gender differences in the relationship between parent drinking and adolescent drinking are poorly understood. As parental alcohol use is a primary early exposure to alcohol for adolescents, it is important to understand how consequences may differ for adolescent males and females. The aim of this paper was to examine gender differences in the relationship between mother's and father's heavy episodic drinking, and its combination, and adolescent drinking. The s le included 2,800 14-15 year olds (48.9% female) living in two-parent households from the Longitudinal Study of Australian Children. The adolescent outcome measure was having had an alcoholic drink in the past year. Mothers and fathers self-reported their frequency of heavy episodic drinking. Covariates included parents' education, smoking, non-English-speaking background, and symptoms of psychological distress. Logistic regression was used to examine the hypotheses. After adjustment for covariates, both mothers' and fathers' heavy episodic drinking significantly increased the likelihood of adolescent drinking. Moreover, fathers' heavy drinking was more strongly related to adolescent drinking for girls. However, there were no gender differences in the relationship between mothers' drinking and adolescent drinking, and the combination of mothers' and fathers' drinking was not more risky than heavy drinking in either parent alone. Parent heavy episodic drinking is a risk factor for adolescent drinking, after controlling for potential confounding variables. Results suggest that girls may be especially vulnerable to parent heavy drinking in early adolescence. This variation should be considered in the design and evaluation of family-based interventions to prevent adolescent drinking.

Abstract: Australian governments fund many place‐based collective impact initiatives like Communities for Children (CfC) states fund family support services to keep at‐risk children out of the child protection system and schools implement many extracurricular programmes. Do these services have a beneficial, cost‐effective collective impact on child well‐being? This paper describes a proof‐of‐concept attempt to address this question by linking for one CfC community in idual‐level data on 5‐ to 12‐year‐old participation in programmes delivered through these three sectors with child outcomes. This exercise was unsuccessful despite the investigators’ prior experience advice from a data linkage expert and our data custodian partners five ARC reviews partners’ good will and ethical safeguards including written, informed parent/carer consent. Obstacles encountered included a lack of data of sufficient quality on children and families’ participation in services, lack of data on children’s outcomes, and prohibitive costs of linkages within government. We offer for others three key lessons: (1) make assumptions explicit (2) talk to technical experts in data custodian organisations early in the planning process and (3) undertake, if possible, an initial scoping exercise. We conclude that despite recent legislative and policy reforms many obstacles we encountered will persist in the absence of a national child well‐being strategy.

Abstract: Stereotactic ablative body radiotherapy (SABR) is currently indicated for inoperable, early‐stage non‐small cell lung carcinoma (NSCLC). Advancements in image‐guidance technology continue to improve treatment precision and enable reductions in planning safety margins. We investigated the dosimetric benefits of margin reduction, its potential to extend SABR to more NSCLC patients and the factors influencing plan acceptability. This retrospective analysis included 61 patients (stage IA–IIIA) treated with conventional radiotherapy. Patients were ineligible for SABR due to tumour size or proximity to organs at risk (OAR). Using Pinnacle auto‐planning, three SABR plans were generated for each patient: a regular planning target volume margin plan, a reduced margin plan (gross tumour volume GTV+3 mm) and a non‐margin plan. Targets were planned to 48Gy/4 or 50Gy/5 fractions depending on location. Plans were compared in terms of target coverage, OAR doses and dosimetric acceptability based on local guidelines. Predictors of acceptability were investigated using logistic regression analysis. Compared to regular margin plans, both reduced margin and non‐margin plans resulted in significant reductions to almost all dose constraints. Dose conformity was significantly worse in non‐margin plans ( P 0.05) and strongly correlated with targets’ surface area/volume ratio ( R 2 = 0.9, P 0.05). 26% of reduced margin plans were acceptable, compared to 54% of non‐margin plans. GTV overlap with OARs significantly affected plan acceptability (OR 0.008, 95% CI 0.001–0.073). Margin reduction significantly reduced OAR doses enabling acceptable plans to be achieved for patients previously excluded from SABR. Indications for lung SABR may broaden as treatment accuracy continues to improve further work is needed to identify patients most likely to benefit.

Abstract: Increasing substance use and decreasing well‐being are typical in adolescence, yet how social contexts shape disparate development during this time is less well‐understood. A latent growth class analysis was conducted that identified groups of early ( N = 706 Age m = 12.20) and middle ( N = 666 Age m = 14.38) adolescents distinguished by rates of substance use and well‐being over three years. In both cohorts, the largest group reported low substance use and high well‐being, with a smaller group exhibiting maladaptive trajectories for both substance use and well‐being. Two additional groups were identified during middle adolescence characterized by either low well‐being or high substance use. Family connectedness was a protective factor, while high peer connectedness was a risk factor for substance‐use groups and low peer connectedness for languishing.

Abstract: A number of international studies have found that the initial stages of the COVID-19 pandemic were associated with reductions in crime, primarily due to changes in the routine activities of the population. However, to date there has been no targeted exploration of how COVID-19 may have influenced youth offending, which may be more heavily impacted by the changes heralded by COVID-19 containment measures. This study examines changes in youth offending in an Australia jurisdiction, Queensland, following the implementation of COVID-19 containment measures from the period April to June 2020. Additionally, differences in impacts across community types were explored. Findings from the panel regression indicated significant declines in youth property offending, offences against the person and public order offences in this period, but no significant changes in illicit drug offences. There were also significant differences across communities according to socio-economic status, per cent Indigenous population, and the extent of commercial or industrial land use. Findings are explored with reference to environmental crime theories and the potential impacts of social, economic and policing changes that occurred in this period.

Abstract: Adolescent peer aggression is a well-established correlate of romantic relational aggression however, the mechanisms underlying this association are unclear. Heavy episodic drinking (or "binge" alcohol use) was examined as both a prior and concurrent mediator of this link in a s le of 282 12-18 year old interviewed four times over 6 years. Path analyses indicated that early peer relational and physical aggression each uniquely predicted later romantic relational aggression. Concurrent heavy episodic drinking fully mediated this effect for peer physical aggression only. These findings highlight two important mechanisms by which peer aggression may increase the risk of later romantic relational aggression: a direct pathway from peer relational aggression to romantic relational aggression and an indirect pathway through peer physical aggression and concurrent heavy episodic drinking. Prevention programs targeting romantic relational aggression in adolescence and young adulthood may benefit from interventions that target multiple domains of risky behavior, including the heavy concurrent use of alcohol.

Abstract: This paper reports on changes in the social‐emotional well‐being of 6‐ to 12‐year‐old children tested before the COVID‐19 pandemic and during 2020 and 2021. Well‐being was assessed using a video game that empowers children to report their own well‐being, including school attachment, social and emotional well‐being, behavioural conformity and family support. We compared well‐being over time for two groups of children in government schools in Queensland, Western Australia and Tasmania. The treatment group of 580 children were tested in 2019 (Time 1) and a second time in mid‐late 2020 and early 2021 (Time 2). The comparison group of 841 children were tested twice before the pandemic. Results showed that children in the treatment group reported significantly lower family support at Time 2 than those in the comparison group. This reduction in perceived family support was stronger for girls. In addition, children in the treatment group who reported lower levels of family support at Time 1 reported a steeper decline in family support by Time 2. Finally, boys in the treatment group reported significantly better behavioural conformity and emotional well‐being relative to girls over time. Results highlight the varied impacts of the pandemic lockdowns and the need to provide continued support to vulnerable families.

Abstract: Using longitudinal data from early adolescence through young adulthood, this study examined the association between different types of postsecondary education (PSE), age of enrollment in PSE, and the trajectory of alcohol use for Canadian young adults ( N = 521). Trajectories of alcohol use were compared across young adults at 2-year colleges, 4-year universities, transfer programs (started at a 2-year college and transferred to a 4-year university), and terminal high school graduates. While initial findings revealed significant differences in the drinking trajectories of 2-year college students and 4-year university students, all differences were accounted for by variability in the age of enrollment. Overall, there were few differences in heavy drinking across types of institutions, but younger students increased their alcohol use more than older students following enrollment. However, young adults who do not attend PSE may be at greatest risk for heavy drinking over time.

Abstract: Protest tourism is visiting a destination with the major aim of viewing or participating in protests. This qualitative study examined the motivations of Hong Kong protest tourists as a starting point for future exploration of distinctions between this emerging type of tourism and other existing categories. Five primary motivations were revealed. Two push motivations were the desire to (1) have special, new experiences that few others have experienced and (2) experience tourist offerings first-hand. Three pull motivations were created by sites providing tourists the opportunity to (i) see a one-time historical event (ii) share the moment with local citizens, even if indirectly and (iii) experience real-time events with a local guide. The findings point to unique temporal and geographic aspects of the interplay between protest tourist motivations and the unique merging of the subject and object of tourism, shedding light on how different tourism experiences can be framed.

Abstract: Many children in developed countries do not receive recommended vaccines on time. However, knowledge about factors related to timeliness remains limited. Quantifying the relative impact of parental attitudes compared with socio-demographic factors for delayed immunization would inform policy responses. Participants in the nationally representative Longitudinal Study of Australian Children were matched with their vaccination histories in the Australian Childhood Immunisation Register (N = 4,121). Information about the children and their families were collected in face-to-face interviews in 2003-2004. We considered whether children had completed the primary course for each recommended antigen due by 6 months old. Children were categorized as either fully immunized, delayed, or totally non-immunized. The outcome was examined using logistic regression. Population attributable fractions were estimated for key predictors. Delayed immunization was significantly associated with indicators of social disadvantage as well as parental disagreement with immunization. Attributable fractions for delayed immunization included lone motherhood (3.8% 95% confidence interval CI [0.8, 6.7]), larger family size (39.5% 95% CI [31.2, 46.8]), residential mobility (3.3% 95% CI [0.1, 6.5]), lack of private hospital insurance (9.4% 95% CI [0.7, 17.3]), a medical condition in the child (2.0% 95% CI [0.2, 3.9]), and parental disagreement with immunization (2.1% 95% CI [0.3, 3.9]). Parental attitudes accounted for a relatively small percentage of delayed infant immunization. In contrast, many children who did not receive vaccines on time were characterized by social disadvantage, especially larger family size. Researchers and policy-makers should consider how to make timely immunization easier for busy parents.

Abstract: Peers are believed to continue as prominent sources of influence for young adults. However, having peers who use alcohol and drugs is associated with depressive symptoms in young adults and research on the effects of having peers who model positive activities beyond adolescence is scarce. In this 10‐year study of 644 Canadian youth (52% female), we used multilevel modeling to examine the effects of within‐person and between‐person differences in the interplay of peer behaviours and changes in depressive symptoms between ages 14 and 25. Data were collected via face‐to‐face interviews and surveys for private topics. Youth with close friends who used drugs and alcohol consistently reported more depressive symptoms at each age, whereas having friends who engaged in positive activities was associated with fewer depressive symptoms, especially during adolescence. Moreover, at times when youth had more substance‐using peers than usual (within person variation), they also reported more symptoms. Substance‐using peer contexts convey both short‐ and long‐term risks for depressive symptoms. However, the protective effects of having peers who are engaged in positive activities, while generally protective, may be reduced in young adulthood. It is possible that older youth withdraw from peers and activities as their depression worsens, and prosocial activities become less supervised by parents, more optional, and more expensive.
