Increased likelihood of distressing and functionally impairing psychotic-like experiences among children with co-occurring internalising and externalising problems.

Among children with psychotic-like experiences (PLEs), the presence of co-occurring psychopathology may distinguish children's self-report of clinically significant experiences (i.e., PLEs that are distressing and/or impairing of daily functioning) from reports of more benign experiences. The aim of this study was to examine whether the likelihood of distressing or impairing PLEs differed according to type of co-occurring psychopathology symptoms. A community sample of 5268 children aged 9-12 years were recruited from Greater London, UK. Participants completed the Psychotic-Like Experiences Questionnaire for Children, and the Strengths and Difficulties Questionnaire to measure internalising and externalising problems. Multinomial logistic regressions were used to determine the likelihood of PLEs being distressing and/or impairing (vs. not) among children with different co-occurring symptom profiles (PLEs only; PLEs with internalising problems only - PLE-I; PLEs with externalising problems only - PLE-E; and PLEs with both internalising and externalising problems - PLE-IE). Children with co-occurring internalising and/or externalising problems had greater odds of distressing and/or impairing PLEs compared to children without co-occurring psychopathology (PLEs only). These associations were moderate for PLE-E and strong for PLE-I and PLE-IE, with the greatest odds of distressing and impairing PLEs evident in the presence of internalising plus externalising comorbidities (odds ratios [with 99 % confidence intervals] for PLE-IE relative to PLE-I = 2.00 [1.34-2.99]; PLE-IE relative to PLE-E = 5.46 [3.78-7.90]). These results affirm the importance of screening for the presence and type of co-occurring psychopathology among children with PLEs to demarcate potentially different treatment needs.

Child Maltreatment and Long-Term Physical and Mental Health Outcomes: An Exploration of Biopsychosocial Determinants and Implications for Prevention.

Child maltreatment rates remain unacceptably high and rates are likely to escalate as COVID-related economic problems continue. A comprehensive and evidence-building approach is needed to prevent, detect and intervene where child maltreatment occurs. This review identifies key challenges in definitions, overviews the latest data on prevalence rates, reviews risk and protective factors, and examines common long-term mental health outcomes for children who experience maltreatment. The review takes a systems approach to child maltreatment outcomes through its focus on the overall burden of disease, gene-environment interactions, neurobiological mechanisms and social ecologies linking maltreatment to mental ill-health. Five recommendations relating to the accurate measurement of trends, research on brain structures and processes, improving the reach and impact of teleservices for detecting, preventing and treating child maladjustment, community-based approaches, and building population-focused multidisciplinary alliances and think tanks are presented.

School Influences on Adolescent Depression: A 6-Year Longitudinal Study Amongst Catholic, Government and Independent Schools, in Victoria, Australia.

This study examined associations between school sector (Government, Catholic or Independent) and depressive symptomology over the secondary school years. Six waves of data collected annually from a representative Australian sample were examined. Multilevel piecewise linear and logistic regression controlling for a variety of demographic variables and protective factors was undertaken. In all sectors, depressive symptomology decreased between 10 and 13 years of age, but significantly increased for girls at age 13. Adolescents in Catholic schools reported significantly fewer symptoms of depression compared to those in Government and Independent schools. Adolescents in Catholic schools were less likely to report clinical levels of depressed mood compared to adolescents in Government schools.

Are there gender-based variations in the presentation of Autism amongst female and male children?

The Questionnaire for Autism Spectrum Conditions (Q-ASC; Attwood, Garnett & Rynkiewicz, 2011) is one of the few screening instruments that includes items designed to assess female-specific ASD-Level 1 traits. This study examined the ability of a modified version of the Q-ASC (Q-ASC-M; Ormond et al., 2018) to differentiate children with and without ASD-Level 1. Participants included 111 parents of autistic children and 212 parents of neurotypical children (5-12 years). Results suggested that the gendered behaviour, sensory sensitivity, compliant behaviours, imagination, and imitation subscales differentiated autistic females from neurotypical females. Compared to autistic males, autistic females had higher scores on gendered behaviour, sensory sensitivity, social masking, and imitation. Results are discussed in relation to early detection of autistic female children.

Associations Between Adolescent Problematic Internet Use and Relationship Problems in Chinese Families: Findings from a Large-scale Survey.

BACKGROUND: Problematic internet use (PIU) is prevalent among Chinese adolescents. There is a need to better understand how the quality of parent-adolescent relationship is associated with adolescent PIU to guide the development of effective prevention and early intervention programs. OBJECTIVE: This study aims to evaluate parent-adolescent conflict and parenting styles as potential risk factors associated with adolescent PIU. METHODS: A sample of 6552 students (aged 10-19 years) from 22 schools in Guangdong, China, was recruited. The participants completed self-report questionnaires measuring their perceptions of conflict with their parents (involving verbal conflict, emotional abuse, and physical abuse) as well as their perceptions of their parents' parenting styles (including parental care and parental control as measured by the Parental Bonding Inventory), and PIU using the Adolescent Pathological Internet Use Scale. Grade level and gender were examined as moderators of these associations. RESULTS: Using multiple regression analyses, we found that greater mother-adolescent conflict, father-adolescent conflict, and parental control, and lower levels of parental care, were associated with higher levels of adolescent PIU (P<.001). The association between mother-adolescent conflict and PIU was stronger in older students than in younger students (P=.04), whereas the association between father-adolescent conflict and PIU was stronger in male students than in female students (P=.02). Compared with those who reported no mother-adolescent conflict, participants who experienced verbal conflict and emotional abuse, but not physical abuse from their mothers, reported higher levels of PIU (P<.001). Compared with those who reported no father-adolescent conflict, participants who experienced verbal conflict, emotional abuse, and physical abuse from their fathers had significantly higher levels of PIU (P<.001, P<.001, and P=.02, respectively). CONCLUSIONS: These findings point to the value of interventions to reduce parental verbal conflict, emotional abuse, and physical abuse, and to increase positive parenting styles, to lower the risk of PIU in Chinese adolescents.

Evaluation of Communities That Care-Effects on Municipal Youth Crime Rates in Victoria, Australia: 2010-2019.

Internationally, youth crime is a significant social problem. Violent youth crime has been rising over the past decade in the state of Victoria, Australia. Communities That Care (CTC) is a coalition training process designed to prevent youth crime. There has been limited evaluation outside the USA. Using a non-experimental design, this study employed official state crime statistics to evaluate the impact on crime as the five-phase CTC process was implemented between 2010 and 2019 across communities in Victoria. The standard five-phase CTC implementation cycle was supplemented with universal programs to reduce sales and supply of alcohol to underage youth (under 18 years). Growth models evaluated community trends in youth crime (all, person, property and deception and other), comparing communities that implemented CTC at phase 4 or greater with communities that had not implemented CTC. In accord with the hypotheses, the study found significant reductions in crimes associated with CTC over the period between 2010 and 2019. A 2% annual reduction in risk was observed for crimes against persons for all age groups (IRR = 0.98, 95% CI [0.96, 0.998]). A 5% annual reduction was observed for crimes of property and deception for adolescents aged between 10 and 17 years (IRR = 0.95, 95% CI [0.90, 0.99]). These findings support CTC as an intervention for preventing youth crime at a population level. Future studies should evaluate intervention mechanisms and economic benefits.

A Component Evaluation of a Randomised Control Community Intervention to Reduce Adolescent Alcohol Use in Australia.

Despite a decline in Australian adolescents reporting to have consumed alcohol, a high proportion of the adolescent population still consumes alcohol. Community-led prevention interventions that systematically and strategically implement evidence-based programs have been shown to be effective in producing population-behaviour change related to youth alcohol and drug use. This study evaluated the post-intervention effects of a multi-component community intervention in Australia. It comprised social marketing targeting adolescents and parents, and a community intervention to reduce underage alcohol sales. Structural equation modelling was used to examine direct and indirect effects of community intervention components on intention and consumption. Self-report surveys (N = 3377) and community sales data (27 communities) were analysed to evaluate the effect of the intervention components on intention and consumption before the age of 18. The intervention reduced alcohol sales to minors (OR = .82). Exposure to the social marketing was significantly associated with household no-alcohol rules (OR = 2.24) and parents not supplying alcohol (OR = .72). The intervention predicted intention not to consume alcohol before age 18; intention was associated with not consuming alcohol (OR = 5.70). Total indirect effects from the intervention through to intention were significant. However, parents setting a rule and not supplying alcohol were the only significant direct effects to intention. Parents setting a rule was directly associated with lower consumption. Overall, the intervention logic was supported by the data modelling. The study extends prior knowledge of community-based interventions to prevent adolescent alcohol use by identifying critical intervention components and effect mechanisms.

Life-course predictors of homelessness from adolescence into adulthood: A population-based cohort study.

INTRODUCTION: Internationally, the prevalence of young adult homelessness is concerning. Few data on life-course predictors from longitudinal studies exist, limiting our capacity to inform prevention strategies at the population-level. METHODS: Data were drawn from a state representative population-based sample of young adults from Victoria, Australia participating in the International Youth Development Study (IYDS; N = 927, 54% female). Participants were recruited in state-representative secondary school samples at Grade 7 (age 13, 2002), with follow-up in Grades 9 (age 15) and 11 (age 17) and at ages 21, 23 and 25. Using longitudinal path modelling, we conducted a series of analyses testing life-course predictors of young adult homelessness across multiple socializing contexts, and the interrelationships among them. RESULTS: The rate of young adult homelessness was 5.5%. Path modelling showed higher levels of family conflict at ages 13 and 15 uniquely predicted homelessness by age 25. This effect remained after accounting for other risk factors in peer-group (e.g., interactions with antisocial peers), school (e.g., low academic performance), and community contexts (e.g., low neighborhood attachment). Peer drug use and interaction with antisocial peers at age 15 mediated the association between family conflict at age 13 and homelessness by age 25. CONCLUSIONS: Findings point to the vulnerability of early adolescents to family conflict. This vulnerability heightens risk for young adult homelessness. Findings strengthen the case for both primary prevention programs that build healthy relationships between family members from early on in adolescence and for investment in homelessness prevention at key developmental periods.

School-based relationships and problematic internet use amongst Chinese students.

The potential for adolescent mental health problems arising from heavy internet use is significant. There is a need to better understand the risk and protective factors related to problematic internet use (PIU) amongst adolescents. This study examined the role of adolescents' perceptions of school-based relationships as potential contextual antecedents to problematic internet use. Specifically, 6552 adolescent students (55.9% boys, 13.51 ± 2. 93 years) from 22 primary and middle schools in southern China completed questionnaires to measure the degree of adolescent conflict with peers, teachers and other staff, school connectedness, perceived classroom atmosphere and problematic internet use. Self-reported data was collected using a two-level stratified sampling. Multiple regression analyses showed that conflict with peers and teachers was positively associated with higher levels of PIU, while school connectedness and perceived classroom atmosphere were negatively associated with PIU. An interaction effect was found for conflict with peers and grade level, such that the association between conflict with peers and PIU was stronger for secondary students compared to primary school students. The results support the need for school-based interventions for PIU to include a focus on conflict with peers and teachers, and for a focus on the enhancement of school connectedness and classroom atmosphere.

Intention to drink and alcohol use before 18 years among Australian adolescents: An extended Theory of Planned Behavior.

INTRODUCTION: Preventing adolescent alcohol use is an international public health priority. To further understand adolescent alcohol use, this study tested a model of adolescent intention to consume alcohol that incorporated multiple social systems influences. METHODS: Participants included 2529 Australian secondary school students (Mage = 14.20; 53.7% female). Participants completed a survey about risk and protective factors for alcohol use at individual, family, school and community levels. Structural Equation Modeling (path analysis) was used to evaluate an extended Theory of Planned Behavior (TPB) that incorporated social system determinants of intention to consume alcohol. RESULTS: The final model explained 60% of the variance in adolescent alcohol use intention. All TPB constructs correlated with intention and experience of lifetime alcohol use. More exposure to information about alcohol use had a weak but significant influence on adolescents' stronger perceived behavioral control. Having less friends who use alcohol, stricter parental rules for adolescent alcohol use, and unfavorable parent attitudes towards alcohol use, were associated with stronger adolescent anti-alcohol attitudes and subjective norms. Community level pro-abstinence attitudes predicted unfavorable adolescent attitudes to alcohol and intention to consume alcohol. Parental rules showed significantly stronger influences on alcohol use intention amongst younger adolescents. CONCLUSIONS: Key social systems around adolescents significantly predicted intention to consume alcohol, and the extended TPB model explained the major variance in adolescent alcohol use. The findings emphasize the importance of multi-level approaches to the prevention of alcohol use. Situation-based factors that could trigger impulsive emotional response may be a future intervention focus.

Alcohol consumption and consequences in adolescents in 68 low and middle-income countries - a multi-country comparison of risks by sex.

AIMS: Alcohol use is a leading risk factor for disease burden among youth. This study estimated sex differences in the prevalence of alcohol use and consequences among adolescents living in low and middle-income countries (LMIC). DESIGN: Multi-staged cross-sectional international standardized self-report questionnaires administered in the classroom. SETTING: The Global school-based student health survey (GSHS) comprised adolescents from 68 LMIC between 2003-2014. PARTICIPANTS: 271,156 students aged 13-17 years old. MEASUREMENTS: Alcohol measures included: past month alcohol consumption, history of intoxication and alcohol-related problems. Regions were based on the World Health Organization definitions: Africa, America, Eastern Mediterranean, Europe, South-east Asia, and Western Pacific. FINDINGS: Overall, males had higher odds of alcohol use (OR = 2.38 [1.91-2.96]), a history of intoxication (OR = 2.64 [2.11-3.31]), and alcohol-related problems (OR = 1.72 [1.41-2.10]) than females. All regions recorded overall greater odds of alcohol use by males versus females; five regions (excluding Europe) recorded greater odds of intoxication in males; and three regions (America, South-east Asia, and Western Pacific) recorded greater odds of alcohol-related problems amongst males. However, there were country-level differences - in some countries, adolescent drinking rates and consequences were comparable by sex. Countries with the highest odds of alcohol use among males compared to females were Indonesia, Myanmar, Cambodia, Tuvalu, Morocco, Senegal, Kiribati, and Thailand. CONCLUSIONS: Among adolescents living in LMIC, males had on average two-fold higher odds of drinking alcohol and experiencing adverse consequences. Growing affluence and improvements in sex equality in societies may increase the future prevalence of hazardous drinking in females in LMICs.

Predicting Alcohol Misuse Among Australian 19-Year-Olds from Adolescent Drinking Trajectories.

BACKGROUND: Alcohol use in adolescence predicts future alcohol misuse. However, the extent to which different patterns of adolescent use present risk remains unclear. OBJECTIVES: This study investigated how adolescent trajectories of alcohol consumption during the school years predict alcohol misuse at age 19 years. METHODS: Data were drawn from 707 students from Victoria, Australia, longitudinally followed for 7 years. Five alcohol use trajectories were identified based on the frequency of alcohol use from Grade 6 (age 12 years) to Grade 11 (age 17 years). At age 19 years, participants completed measures indicating Heavy Episodic Drinking (HED), dependency - Alcohol Use Disorders Identification Test (AUDIT) and social harms. RESULTS: At 19 years of age, 64% of participants reported HED, 42% high AUDIT scores (8+), and 23% social harms. Participants belonging to a steep escalator trajectory during adolescence had twice the odds at 19 years of age of high AUDIT scores and social harms, and three times greater odds of HED than participants whose alcohol use slowly increased. Stable moderate consumption was also associated with an increased risk of HED compared to slowly increasing use. Abstinence predicted a reduced likelihood of all forms of misuse at 19 years of age compared to slowly increased alcohol use. CONCLUSIONS: Trajectories of drinking frequency during adolescence predict alcohol misuse at age 19 years. Although rapid increasing use presents the greatest risk, even slowly increasing drinking predicts increased risk compared to abstinence. The findings indicate that alcohol policies should recommend nonuse and reduced frequency of use during adolescence.

Familial alcohol supply, adolescent drinking and early alcohol onset in 45 low and middle income countries.

AIMS: This study estimated the extent of familial alcohol supply in 45 low and middle income countries (LMIC), and examined the country-level effects of familial alcohol supply on adolescents' alcohol use. METHOD: We used data from 45 LMICs that participated in the Global School-Based Student Health Survey (GSHS) between 2003 and 2013 (n = 139,840). The weighted prevalence of familial alcohol supply in each country was estimated. Multilevel binary and ordinal logistic regression analyses were used to examine the country-level effect of familial alcohol supply on early onset of alcohol use (first alcohol before 12), past 30-day alcohol use, lifetime drunkenness and alcohol-related social problems. RESULTS: There were large variations between LMICs in the prevalence of familial alcohol supply and pattern of adolescent alcohol use. The prevalence of familial supply ranged from 0.1% in Tajikistan to 23.8% in St Lucia. It was estimated that a one percentage change in prevalence of familial alcohol supply was associated with 10%, 12% and 12% change in the odds of lifetime drunkenness (OR = 1.10, 95% CI = [1.04, 1.16]), early onset of alcohol use (OR = 1.12, 95% CI = [1.07, 1.08]) and more frequent drinking in the past month (OR = 1.12, 95% CI = [1.04, 1.20]). CONCLUSION: There were large variations in the prevalence of familial alcohol supply and adolescent alcohol use among LMICs. Adolescents in countries with higher prevalence of familial alcohol supply were more likely to start using alcohol at an earlier age, to have used alcohol in the past 30 days and experience intoxication.

An Examination of Gender Differences in the Association of Adolescent Substance use with Eating and Weight Loss Attitudes.

OBJECTIVE: To assess gender differences in the relationship between eating and weight loss attitudes (EWAs), and 30-day tobacco and alcohol use among adolescents, while controlling for potential confounds (age, country of birth, psychological distress, pubertal development, peer alcohol and tobacco use, and sexual activity). METHODS: School students aged between 11 and 17 years (N = 10,273) from high schools in the State of Victoria (Australia) completed surveys in class under conditions of anonymity and confidentiality. RESULTS: The interaction between EWAs and gender was significant for tobacco use but not for alcohol use, indicating that the effect of EWAs on tobacco use, but not alcohol use, vary by gender. CONCLUSIONS: Tobacco use was related to EWAs in adolescent females but not males, and this is consistent with the possibility that females use tobacco in an instrumental fashion to control weight. Implications and Contribution: Female adolescents high in eating and weight loss attitudes were more likely to engage in tobacco use. In contrast, eating and weight loss attitudes were not related to male tobacco use. These results point to the potential importance of developing gender-specific approaches towards addressing problematic behaviors in adolescent populations.

Social marketing and community mobilisation to reduce underage alcohol consumption in Australia: A cluster randomised community trial.

BACKGROUND AND AIMS: In many countries adolescent alcohol use is a major health problem. To supplement national policies, it is important to trial community interventions as a potential strategy to prevent adolescent alcohol use. METHODS: This study evaluated a multicomponent community intervention that included community mobilisation, social marketing, and the monitoring of alcohol sales to minors. Evaluation was a clustered randomised trial design with 14 intervention and 14 control communities. Prior to randomisation, communities were matched on socioeconomic status and location. Intervention communities were not blinded. PARTICIPANTS: 3545 Year 8 students (M = 12 years) were surveyed at baseline from 75 schools; 3377 students were surveyed post intervention in 2013 from 54 schools. OUTCOMES: It was hypothesised that the primary outcome, individual alcohol consumption in last 30 days, after the intervention would be 15% lower in intervention communities. Secondary outcomes were consumption in the past year and intention not to drink before age 18. RESULTS: The intervention communities showed larger relative reductions compared to the controls in last 30-day consumption and past year (10%), but not significantly different. A significantly lower proportion of participants in the intervention community (63%), compared to the controls (71%), reported intending to drink before 18 years old. Subgroup analysis identified regional and state differences for some secondary measures. CONCLUSIONS: Intervention assignment was associated with lower adolescent intention to drink before the age of 18. However, more intensive and longer-term intervention may be required to measure significant differences in behaviour change. TRIAL REGISTRATION: ACTRN12612000384853.

Testing the Social Interaction Learning Model's Applicability to Adolescent Substance Misuse in an Australian Context.

BACKGROUND: Parents and peers both influence the development of adolescent substance misuse, and the Social Interaction Learning (SIL) model provides a theoretical explanation of the paths through which this occurs. OBJECTIVE: The SIL model has primarily been tested with conduct outcomes and in US samples. This study adds to the literature by testing the SIL model with four substance use outcomes in a sample of Australian youth. METHOD: We used structural equation modeling to test the fit of the SIL model to a longitudinal sample (n = 907) of students recruited in grade 5 in Victoria, Australia participating in the International Youth Development Study, who were resurveyed in grades 6 and 10. RESULTS: The model fit was good (χ2(95) = 248.52, p < .001; RMSEA = .04 [90% CI: .036 - .049]; CFI = .94; SRMR = .04). Path estimates from parenting to antisocial behavior and from antisocial behavior to antisocial peers were significant. In turn, having antisocial peers was significantly related to alcohol use, binge drinking, tobacco use, and marijuana use. From parenting, only the direct path to marijuana use was significant, but indirect effects were significant. CONCLUSIONS: The SIL model illustrates that parenting plays an early role in the formation of adolescent peer relations that influence substance misuse and identifies etiological pathways that can guide the targets of prevention. The SIL pathways appear robust to the Australian social and policy context.

Parental supply of alcohol and adolescent drinking: a multilevel analysis of nationally representative data.

BACKGROUND: Existing research on parental supply of alcohol analyses the effects of self-reported parental supply on adolescent drinking using individual level data. This study examined the contextual effect of parental supply of alcohol on adolescent alcohol use by examining the association between the prevalence of parental supply in each Australian state and adolescent alcohol use using a multilevel analytic framework. METHODS: Adolescent samples (Age: 12-17) were drawn from the four National Drug Strategy Household Surveys (2004, 2007, 2010 and 2013; N = 6803). The prevalence of parental supply of alcohol, defined as the weighted percentage of sample who reported obtaining alcohol from their parents, was estimated in each state and territory across the four surveys. Three multilevel logistic regressions were used to examine the contextual effects of parental supply prevalence on adolescents' alcohol use in the past 12 months, weekly drinking and heavy drinking. RESULTS: Overall, adolescents' rates of past 12 months alcohol use, heavy drinking and weekly drinking between 2004 and 2013 were 40.1, 14.4 and 6.4% respectively. The prevalence of parental supply was significantly associated with past 12 months alcohol use (OR = 1.06, p < .001) and heavy drinking (OR = 1.04, p < .001) but not with weekly drinking (OR = 1.03, p = .189). The results were adjusted for gender, age, socio-economic index for area, place of birth, survey year and prevalence of peer supply. CONCLUSION: A high prevalence of parental supply in a region was associated with heavier adolescent drinking, regardless of whether adolescents primarily obtained their alcohol from their own parents.
