- Abstract
There is a dearth of research on delinquency, school context, and risk factors across developed and developing nations. Using representative samples and matched surveys, we examined delinquency among cohorts in Mumbai, India (N = 3,717); Victoria, Australia (N = 1,842); and Washington State (WA), United States (N = 1,828). We used multivariate Poisson hierarchical linear modeling. Risk factor and delinquency levels varied across sites. Delinquency clustered within certain schools, particularly in Mumbai. Community disorganization exhibited an association with delinquency as a school-level context effect in Mumbai and Victoria. Peer delinquency, sensation seeking, and poor family management exhibited cross-nationally consistent associations with delinquency. Programs that target schools, the clustering of problem behaviors, and cross-nationally consistent risk factors should be considered internationally.

INTRODUCTION AND AIMS: This study prospectively investigates behavioural and social antecedents of different patterns of adolescent cannabis use, specifically, early adolescent onset cannabis use and late onset occasional use. DESIGN AND METHODS: The sample comprised 852 adolescents (53% female) drawn from the Australian arm of the International Youth Development Study. Data were collected via self-report surveys. Risk and protective factors from a modified version of the Communities That Care youth survey were measured in fifth grade (mean [M] = 10.9 years, SD = 0.4). Frequency of cannabis use was measured at six time-points throughout adolescence (ages 12-19 years). RESULTS: Early adolescent onset cannabis use (10.7% of the sample [n = 91]) was predicted by childhood family-related factors including poor family management, family history of antisocial behaviour and attachment to parents. Cigarette use and drinking until drunk were the strongest predictors of early adolescent onset cannabis use. Cumulative risks associated with community, family, peer/individual environments and early substance use (cigarettes, alcohol) in childhood were predictive of early adolescent onset cannabis use (e.g. relative risk ratio = 2.64; 95% confidence interval 1.40-4.97 for early substance use). Family and early substance use-related cumulative risks were predictive of late adolescent onset occasional cannabis use (n = 231; 27%). Cumulative early substance use risk was the strongest independent predictor of both early adolescent onset and late adolescent onset occasional cannabis use. DISCUSSION AND CONCLUSIONS: Primary prevention efforts should focus on reducing exposure and access to licit substances during late childhood and delaying the onset of use. Prevention and intervention targeted toward the family environment also appears likely to be important in the prevention of early adolescent onset cannabis use.

- Abstract
Youth residing in out-of-home care settings have often been exposed to childhood trauma, and commonly report experiencing adverse outcomes after transitioning from care. This meta-analysis appraised internationally published literature investigating the impact of transitional programme participation (among youth with a baseline age of 15-24 years) on post-transition outcomes of housing, education, employment, mental health and substance use. A comprehensive search of sociology (e.g. ProQuest Sociology), psychology (e.g. PsycInfo) and health (e.g. ProQuest Family Health) electronic abstraction databases was conducted for the period 1990-2014. Search terms included 'out-of-home care', 'transition', 'housing', 'education', 'employment', 'mental health' and 'substance use'. Nineteen studies, all from the United States, met the inclusion criteria and were included in the meta-analysis. Living independently and homelessness were the most commonly described housing outcomes. Rates of post-transition employment varied, while rates of post-secondary education were low. Depression and alcohol use were commonly reported among transitioning youth. Findings of the meta-analysis showed that attention should be given to the potential benefit of transitional programme participation on outcomes such as housing, employment and education. Moderator analyses showed that these benefits may differ based on study design, sample size and sampling unit, but not for mean age or gender. Detailed and rigorous research is needed internationally to examine the characteristics of transitional programmes resulting in more successful outcomes for youth, and whether these outcomes are sustained longitudinally.

- Abstract
OBJECTIVE: Our study examined the psychological outcomes associated with failed ART treatment outcomes in men and women. SEARCH STRATEGY: A systematic search for studies published between January 1980 and August 2015 was performed across seven electronic databases. INCLUSION CRITERIA: Studies were included if they contained data on psychosocial outcomes taken pre and post ART treatment. DATA EXTRACTION AND SYNTHESIS: A standardised form was used to extract data and was verified by two independent reviewers. Studies were meta-analysed to determine the association of depression and anxiety with ART treatment outcomes. Narrative synthesis identified factors to explain variations in the size and directions of effects and relationships explored within and between the studies. MAIN RESULTS: Both depression and anxiety increased after a ART treatment failure with an overall pooled standardised mean difference (SMD) of 0.41 (95% CI: 0.27, 0.55) for depression and 0.21 (95% CI: 0.13, 0.29) for anxiety. In contrast, depression decreased after a successful treatment, SMD of -0.24 (95% CI: -0.37,-0.11). Both depression and anxiety decreased as time passed from ART procedure. Nonetheless, these remained higher than baseline measures in the group with the failed outcome even six months after the procedure. Studies included in the narrative synthesis also confirmed an association with negative psychological outcomes in relation to marital satisfaction and general well-being following treatment failure. CONCLUSION: Linking ART failure and psychosocial outcomes may elucidate the experience of treatment subgroups, influence deliberations around recommendations for resource allocation and health policy and guide patient and clinician decision making.

- Abstract
Comorbidity between problem gambling and internalising disorders (anxiety and depression) has long been recognised. However, it is not clear how these relationships develop, and what factors can foster resilience to both conditions. The current study draws on longitudinal cohort data to investigate: 1) the cross-sectional and longitudinal relationships between problem gambling and internalising symptoms; 2) whether there are common and/or specific social environmental factors protective against both internalising symptoms and problem gambling in young adulthood; and 3) interactive protective factors (i.e., those that moderate the relationship between problem gambling and internalising symptoms).

- Abstract
Identifying specific aspects of peer social norms that influence adolescent substance use may assist international prevention efforts. This study examines two aggregated measures of social norms in the school setting and their predictive association with substance (alcohol, tobacco and marijuana) use 2 years later in a large cross-national population-based cohort of adolescents. The primary hypothesis is that in Grade 7 both "injunctive" school norms (where students associate substance use with "coolness") and "descriptive" norms (where student substance use is common) will predict Grade 9 substance use. Data come from the International Youth Development Study, including 2,248 students (51.2% female) in the US and Australia attending 121 schools in Grade 7. Independent variables included injunctive norms (aggregating measures of school-wide coolness ratings of each substance use) and descriptive norms (aggregating the prevalence of school substance use) in Grade 7. Dependent variables included binge drinking and current use of alcohol, tobacco and marijuana in Grade 9. Associations between each type of school-wide social norm and substance use behaviors in Grade 9 were tested using multilevel logistic regression, adjusting for covariates. In unadjusted models, both injunctive and descriptive norms each significantly predicted subsequent substance use. In fully adjusted models, injunctive norms were no longer significantly associated with Grade 9 use, but descriptive norms remained significantly associated with tobacco and marijuana use in the expected direction. The findings identify descriptive social norms in the school context as a particularly important area to address in adolescent substance use prevention efforts.

- Abstract
The impact of alcohol-related violence on individuals and society continues to receive attention from both media and policy makers. However, the longitudinal relationship between alcohol consumption and violence is unclear, with findings from prospective studies producing mixed results. The current study utilized Australian data from the International Youth Development Study to examine longitudinal relationships between alcohol consumption and severe interpersonal violence across the developmental periods of early adolescence to late adolescence/emerging adulthood. The full sample comprised 849 adolescents (53.8 % female) who had been followed up over a 5 year period, from Grade 7 secondary school (age 13) until Grade 11 secondary school (age 17). Cross-lagged path analysis was used to examine reciprocal relationships between alcohol consumption and interpersonal violence; analyses controlled for a range of covariates considered to be common risk factors for both behaviors. Alcohol use during early and mid adolescence was found to predict violence 2 years later, whereas a bi-directional relationship between adolescent heavy episodic drinking and violence was observed. Some of these relationships were not significant when covariates such as family conflict and affiliation with antisocial and drug using friends were included in the models. These findings suggest that risk processes begin in late childhood or very early adolescence; efforts to reduce one problem behavior are likely to reduce the other. Further, the role that social and family contexts have in influencing the relationships between alcohol use and interpersonal violence should be considered in future research to better inform preventive efforts.

- Abstract
The purpose of this study was to investigate the influence of exposure to others' drink driving during adolescence on self-reported driving under the influence (DUI) of alcohol in young adulthood. Data were drawn from 1956 participants with a driving license enrolled in the International Youth Development Study from Victoria, Australia. During 2003 and 2004, adolescents in Grades 7, 9 and 10 (aged 12-17) completed questionnaires examining whether they had ridden in a vehicle with a driver who had been drinking, as well as other demographic, individual, peer and family risk factors for DUI. In 2010, the same participants (aged 18-24) then reported on their own DUI behaviour. 18% of young adults with a driving license reported DUI in the past 12 months. Exposure to others' drink driving during adolescence was associated with an increased likelihood of DUI as a young adult (OR=2.13, 95% CI 1.68-2.69). This association remained after accounting for the effects of other potential confounding factors from the individual, peer and family domains (OR=1.62, 95% CI 1.23-2.13). Observing the drink driving behaviours of others during adolescence may increase the likelihood of DUI as a young adult. Strategies to reduce youth exposure to drink driving are warranted.

- Abstract
OBJECTIVE: To prospectively examine the relation between pubertal stage and the onset and course of depressive symptoms. METHOD: The design was a three-wave longitudinal study of health and social development using statewide community samples in Washington, United States, and Victoria, Australia. Approximately 5,769 students initially ages 10 to 15 years were assessed for depressive symptoms with the Short Mood and Feelings Questionnaire. Pubertal status was assessed using a self-report version of the Pubertal Development Scale. RESULTS: Advancing pubertal stage carried higher risks for depressive symptoms in female subjects in all of the three study waves. The pubertal rise in female depressive symptoms was due to both higher risk for incident cases and an even greater effect on risks for persistence of depressive symptoms. Report of poor emotional control 12 months earlier carried a twofold higher risk for incident depressive symptoms and largely explained the pubertal rise in female incident cases. High family conflict and severity of bullying also predicted persistence of depressive symptoms. Preexisting depressive symptoms were not associated with later increases in the rate of pubertal transition. CONCLUSIONS: Advancing pubertal stage carries risks for both the onset and persistence of depressive symptoms in females. Social adversity around puberty predicts the persistence of symptoms but does not account for a pubertal rise in female depression. A report of poor emotional control may be a useful marker of girls at risk for depressive symptoms and as a target for preventive intervention.

- Abstract
We investigated whether a composite genetic factor, based on the combined actions of catechol-O-methyltransferase (COMT) (Val(158)Met) and serotonin transporter (5HTTLPR) (Long-Short) functional loci, has a greater capacity to predict persistence of anxiety across adolescence than either locus in isolation. Analyses were performed on DNA collected from 962 young Australians participating in an eight-wave longitudinal study of mental health and well-being (Victorian Adolescent Health Cohort Study). When the effects of each locus were examined separately, small dose-response reductions in the odds of reporting persisting generalized (free-floating) anxiety across adolescence were observed for the COMT Met(158) [odds ratio (OR) = 0.85, 95% confidence interval (CI) = 0.76-0.95, P = 0.004] and 5HTTLPR Short alleles (OR = 0.88, CI = 0.79-0.99, P = 0.033). There was no evidence for a dose-response interaction effect between loci. However, there was a double-recessive interaction effect in which the odds of reporting persisting generalized anxiety were more than twofold reduced (OR = 0.45, CI = 0.29-0.70, P < 0.001) among carriers homozygous for both the COMT Met(158) and the 5HTTLPR Short alleles (Met(158)Met + Short-Short) compared with the remaining cohort. The double-recessive effect remained after multivariate adjustment for a range of psychosocial predictors of anxiety. Exploratory stratified analyses suggested that genetic protection may be more pronounced under conditions of high stress (insecure attachments and sexual abuse), although strata differences did not reach statistical significance. By describing the interaction between genetic loci, it may be possible to describe composite genetic factors that have a more substantial impact on psychosocial development than individual loci alone, and in doing so, enhance understanding of the contribution of constitutional processes in mental health outcomes.

- Abstract
BACKGROUND: The mesolimbic structures of the brain are important in the anticipation and perception of reward. Moreover, many drugs of addiction elicit their response in these structures. The M5 muscarinic receptor (M5R) is expressed in dopamine-containing neurones of the substantia nigra pars compacta and ventral tegmental area, and regulates the release of mesolimbic dopamine. Mice lacking M5R show a substantial reduction in both reward and withdrawal responses to morphine and cocaine. The CHRM5, the gene that codes for the M5R, is a strong biological candidate for a role in human addiction. We screened the coding and core promoter sequences of CHRM5 using denaturing high performance liquid chromatography to identify common polymorphisms. Additional polymorphisms within the coding and core promoter regions that were identified through dbSNP were validated in the test population. We investigated whether these polymorphisms influence substance dependence and dose in a cohort of 1947 young Australians. RESULTS: Analysis was performed on 815 participants of European ancestry who were interviewed at wave 8 of the cohort study and provided DNA. We observed a 26.8% increase in cigarette consumption in carriers of the rs7162140 T-allele, equating to 20.1 cigarettes per week (p=0.01). Carriers of the rs7162140 T-allele were also found to have nearly a 3-fold increased risk of developing cannabis dependence (OR=2.9 (95%CI 1.1-7.4); p=0.03). CONCLUSION: Our data suggest that variation within the CHRM5 locus may play an important role in tobacco and cannabis but not alcohol addiction in European ancestry populations. This is the first study to show an association between CHRM5 and substance use in humans. These data support the further investigation of this gene as a risk factor in substance use and dependence.

- Abstract
ISSUE ADDRESSED: Mental health promotion aimed at populations with low socio-economic status (SES) may benefit by investigating prevention strategies that effectively address related child and adolescent problems. METHODS: Evidence from a number of literature reviews and program evaluations was synthesised. First, the impact of SES on development from childhood to adulthood is considered in light of research on substance abuse, violence, crime, and child development problems. Second, evaluations of interventions are reviewed to identify those that have shown outcomes in research studies (efficacy) or in real-world settings (effectiveness) in reducing developmental problems associated with low SES. Low SES is measured in different ways including low levels of education and/or income or definitions that combine several variables into a new indicator of low SES. RESULTS: Factors associated with low SES are also associated to varying extent with the development of violence and crime, substance abuse and child health problems. Interventions that address underlying determinants of low SES show strong efficacy in decreasing adolescent crime and violence and effectiveness in improving child health outcomes. Although there is limited efficacy evidence that substance abuse prevention can be effectively addressed by targeting low SES, programs designed to improve educational pathways show some efficacy in reducing aspects of adolescent substance use. CONCLUSION: Mental health promotion strategies can draw on the approaches outlined here that are associated with the prevention of child and adolescent problems within low SES communities. Alternatively, such interventions could be supported in mental health promotion policy as they may assist in preventing related problems that undermine mental health.

- Abstract
Issue Addressed: To undertake a detailed analysis of the content of anti-bullying policies in schools in New Zealand (NZ) and Victoria, Australia.Methods: The content of anti-bullying policies from 253 NZ schools and 93 Victorian schools were analysed in terms of definitions of bullying behaviour; reporting, recording and responding to bullying incidents; communicating and evaluating the policy; and outlining strategies for preventing bullying.Results: There was a wide range in 'policy scores' between schools, and Victorian schools scored higher on nearly every area compared with NZ schools. In both regions, definitions rarely included bullying on the grounds of homophobia, religion or disability; or bullying between adults and students. Policies also lacked detail about the responsibilities of non-teaching staff in dealing with bullying, and rarely described follow-up after a bullying incident. Few policies explained how the policy would be evaluated, and many failed to mention preventive strategies.Conclusion: This study highlights some important areas that are deficient in NZ and Victorian school anti-bullying policies, and emphasises the need for guidance on how schools can develop an effective anti-bullying policy. Having more comprehensive anti-bullying policies will give schools a much better chance of reducing bullying. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Issue Addressed: Health promotion with adolescents spans many contexts including schools. Income and its distribution, education and social exclusion are key social determinants of health. Exclusionary school policies such as school suspension contribute to exclusion, increase the likelihood of school dropout (reducing educational and subsequent employment opportunities), and negatively impact on student wellbeing. Often excluded students are from socio-economically disadvantaged areas. This paper examines associations between area level socio-economic status (SES) and school suspension in Australian students.Methods: Students (8,028) in years 6 (n = 4393) and 8 (n = 3635) completed a comprehensive social development survey administered in schools in 30 socio-economically stratified communities in 2006.Results: Associations between area level SES and school suspension were found. Relative to students in the lowest SES quartile communities, students in mid level and high SES had lower suspension rates. These effects remained after controlling for antisocial behaviour, gender, age and the established risk factors of poor family management, interaction with antisocial peers and academic failure.Conclusions: Students living in low SES areas are exposed to higher rates of school suspension, at similar levels of adjustment problems. Assisting schools, particularly those with disadvantaged students, to foster school engagement is essential for schools committed to health promotion. [ABSTRACT FROM AUTHOR]- Published

The prevalence of behavioral inhibition in toddlers was examined in five cultures. Participants in this study included 110 Australian, 108 Canadian, 151 Chinese, 104 Italian, and 113 South Korean toddlers and their mothers who were observed during a structured observational laboratory session. Matched procedures were used in each country, with children encountering an unfamiliar stranger with a truck and a robot. Indicators of inhibition included the length of time toddlers delayed before approaching the stranger and the duration of contact with their mother while the stranger was in the room. Results were generally consistent with expectations and showed differences between eastern and western cultures; Italian and Australian toddlers were less inhibited than toddlers from the other countries, whereas Chinese and South Korean toddlers were more inhibited. The implications of these findings are discussed and a research agenda for further exploration of inhibition is outlined.

There is a dearth of research on delinquency, school context, and risk factors across developed and developing nations. Using representative samples and matched surveys, we examined delinquency among cohorts in Mumbai, India (N = 3,717); Victoria, Australia (N = 1,842); and Washington State (WA), United States (N = 1,828). We used multivariate Poisson hierarchical linear modeling. Risk factor and delinquency levels varied across sites. Delinquency clustered within certain schools, particularly in Mumbai. Community disorganization exhibited an association with delinquency as a school-level context effect in Mumbai and Victoria. Peer delinquency, sensation seeking, and poor family management exhibited cross-nationally consistent associations with delinquency. Programs that target schools, the clustering of problem behaviors, and cross-nationally consistent risk factors should be considered internationally., (© 2018 Society for Research on Adolescence.)

- Abstract
This study sought to appraise internationally published literature investigating bullying in its association with deliberate self-harm (DSH). A systematic review and series of meta-analyses using random effects models were conducted. A total of 68 effect sizes, analyzing data from 156,284 adolescents aged 11-19 years were examined. Results showed significant associations between both traditional bullying perpetration (OR 1.81, 95% CI [1.33, 2.47], p < .0001) and victimization (OR 2.34, 95% CI [1.89, 2.89], p < .0001) and DSH. Cyber-bullying victimization (OR 3.55, 95% CI [2.71, 4.65], p < .0001) and the co-occurrence of traditional and cyber-bullying victimization (OR 3.39, 95% CI [1.56, 7.37], p = .002) were also associated with DSH. Moderator analyses showed variation in results based on methodological- and sample-level variables. Findings suggested that exposure to bullying, either as perpetrators or victims, poses risks for DSH.

- Abstract
Purpose: Reciprocal prospective associations between adolescent antisocial behavior and depressive symptoms were examined., Methods: Seventh grade students (average age 13 years; N=2,314/2,348) were surveyed (T1), and then followed-up 12 (T2) and 24 months (T3) later, using the same methods in Washington State and Victoria, Australia., Results: Negative binomial regressions showed antisocial behavior (T1, T2) did not prospectively predict depressive symptoms (T2, T3). T1 multivariate predictors for T2 depressive symptoms included female gender (incident rate ratio [IRR] = 1.70), prior depressive symptoms (IRR = 1.06), alcohol use (IRR = 1.13), family conflict (IRR = 1.13), antisocial peers (IRR = 1.08) and bullying victimization (IRR = 1.06). Depressive symptoms (T1, T2) did not predict antisocial behavior (T2, T3). T1 multivariate predictors for T2 antisocial behavior included female gender (IRR = .96), age (IRR = .97), prior antisocial behavior (IRR = 1.32), alcohol use (IRR = 1.04), antisocial peers (IRR = 1.11) and academic failure (IRR = 1.03)., Conclusions: Depressive symptoms and antisocial behaviors showed considerable predictive stability in early adolescence but were not reciprocally related. Prevention and intervention strategies in adolescence may benefit by targeting common predictors such as alcohol, peer interactions and early symptoms for depression and antisocial behavior., Competing Interests: Declaration of conflicting interests None to declare.

- Abstract
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.

- Abstract
Introduction: Poor family management and antisocial peer associations are related risk factors for negative outcomes such as adolescent substance misuse and conduct disorders. The relationship between family management and antisocial peer associations is complex. The purpose of this study was to test the reciprocal relationships between youth-reports of poor family management and antisocial peer associations over multiple time-points., Methods: We used four data points (5th-11th grade) from the Australian arm of the longitudinal International Youth Development Study (IYDS) to test a random-intercepts cross-lagged path model (N = 922)., Results: The model fit the data well with path estimates showing that poor family management predicted greater antisocial peer associations at the next wave but not the reverse. A second model included a third autoregressive path to control for youth's own antisocial behavior; the direction of the relationships between poor family management and antisocial peer associations did not change., Conclusions: These results indicate that across adolescence poor family management predicts greater antisocial peer association, which provides evidence that family-focused interventions are an important prevention strategy even in adolescence., (Copyright © 2018 The Foundation for Professionals in Services for Adolescents.

- Abstract
Youth residing in out-of-home care settings have often been exposed to childhood trauma, and commonly report experiencing adverse outcomes after transitioning from care. This meta-analysis appraised internationally published literature investigating the impact of transitional programme participation (among youth with a baseline age of 15-24 years) on post-transition outcomes of housing, education, employment, mental health and substance use. A comprehensive search of sociology (e.g. ProQuest Sociology), psychology (e.g. PsycInfo) and health (e.g. ProQuest Family Health) electronic abstraction databases was conducted for the period 1990-2014. Search terms included 'out-of-home care', 'transition', 'housing', 'education', 'employment', 'mental health' and 'substance use'. Nineteen studies, all from the United States, met the inclusion criteria and were included in the meta-analysis. Living independently and homelessness were the most commonly described housing outcomes. Rates of post-transition employment varied, while rates of post-secondary education were low. Depression and alcohol use were commonly reported among transitioning youth. Findings of the meta-analysis showed that attention should be given to the potential benefit of transitional programme participation on outcomes such as housing, employment and education. Moderator analyses showed that these benefits may differ based on study design, sample size and sampling unit, but not for mean age or gender. Detailed and rigorous research is needed internationally to examine the characteristics of transitional programmes resulting in more successful outcomes for youth, and whether these outcomes are sustained longitudinally., (© 2016 John Wiley & Sons Ltd.)

- Abstract
Gender differences in externalizing and internalizing pathways from child abuse to adult crime were examined across four waves of an extended longitudinal study ( N = 186 males and 170 females) using multiple-group structural equation modeling. Results show that child abuse was associated with both internalizing and externalizing behaviors in the elementary school years for both males and females. However, gender differences were found such that internalizing behaviors increased the risk of adult crime for females only, and externalizing behaviors increased the risk of adult crime for males only. Internalizing behaviors among males actually lessened the risk of adult crime, and externalizing behaviors were unrelated to adult crime among females. Findings confirm distinct pathways leading from child abuse to later crime for males and females, which is important for prevention and intervention strategies.

- Abstract
Aim: To evaluate the preliminary validity and reliability of the myTREEHOUSE Self-Concept Assessment for children with cerebral palsy (CP) aged 8 to 12 years., Method: The myTREEHOUSE Self-Concept Assessment includes 26 items divided into eight domains, assessed across three Performance Perspectives (Personal, Social, and Perceived) and an additional Importance Rating. Face and content validity was assessed by semi-structured interviews with seven expert professionals regarding the assessment construct, content, and clinical utility. Reliability was assessed with 50 children aged 8 to 12 years with CP (29 males, 21 females; mean age 10y 2mo; Gross Motor Function Classification System [GMFCS] level I=35, II=8, III=5, IV=1; mean Wechsler Intelligence Scale for Children - Fourth Edition [WISC-IV]=104), whose data was used to calculate internal consistency of the scale, and a subset of 35 children (20 males, 15 females; mean age 10y 5mo; GMFCS level I=26, II=4, III=4, IV=1; mean WISC-IV=103) who participated in test-retest reliability within 14 to 28 days., Results: Face and content validity was supported by positive expert feedback, with only minor adjustments suggested to clarify the wording of some items. After these amendments, strong internal consistency (Cronbach's α 0.84-0.91) and moderate to good test-retest reliability (intraclass correlation coefficient 0.64-0.75) was found for each component., Interpretation: The myTREEHOUSE Self-Concept Assessment is a valid and reliable assessment of self-concept for children with CP aged 8 to 12 years., (© 2017 Mac Keith Press.)

- Abstract
This study examined cross-national similarities in a developmental model linking early age of alcohol use onset to frequent drinking and heavy drinking and alcohol problems 1 and 2 years later in a binational sample of 13-year-old students from two states: Washington State, USA and Victoria, Australia (N = 1833). A range of individual, family, school, and peer influences was included in analyses to investigate their unique and shared contribution to development of early and more serious forms of alcohol use and harms from misuse. Data were collected annually over a 3-year period from ages 13 to 15. Analyses were conducted using multiple-group structural equation modeling. For both states, early use of alcohol predicted frequent drinking, which predicted alcohol problems. Family protective influences had neither direct effects on heavy drinking nor effects on alcohol harm in either state, whereas school protection directly reduced the risk of heavy drinking in both states. Exposure to antisocial peers and siblings predicted a higher likelihood of heavy drinking and alcohol harm for students in both Washington and Victoria. Implications for the prevention of adolescent alcohol problems are discussed., Competing Interests: Compliance with Ethical Standards: Conflict of Interest.

- Abstract
The use of substances among youth experiencing homelessness is an important issue in the context of addressing the developing burden of morbidities arising due to illness, injury, physical and mental health concerns, and low rates of health care utilization among this population group. Youth experiencing homelessness report engaging in and being victimized by various forms of sexual behavior. Of interest in this systematic review were published studies investigating substance use in its association with perpetration of sexual offenses, engagement in sexual risk behavior, or experience of sexual victimization among homeless youth. A systematic search of 12 psychology, health, and social science electronic databases was conducted. Search terms included "homeless*," "youth," "sex crimes," "sexual victimization," "survival sex," "rape," "drugs," and "substance abuse." Twenty-three studies were identified that met the inclusion criteria. No studies statistically examining substance use in its association with perpetrating sexual offenses were located. Findings showed substance use was generally associated with sexual risk behavior or sexual victimization; however, it remains unclear whether substance use precedes or follows these behaviors and experiences. It is possible substances are used by homeless youth as a means of coping with sexual risk behavior and victimization. Implications of the review findings in relation to prevention and intervention approaches aimed to decrease the incidence and severity of health concerns among homeless youth are discussed., (© The Author(s) 2015.)

- Abstract
The goal of this study was to examine and cross-nationally compare the peer group patterns of alcohol-drinking behaviors among cohorts of early adolescents (ages 11-14 years) in Victoria, Australia, and Washington State, United States. Latent transition analysis revealed that after 1 year, transitions congruent with peer influence (whereby non-drinking adolescents initiated alcohol use in the presence of drinking peers) and reverse peer influence were observed in both states; however, transitions congruent with peer selection (whereby drinking adolescents self-selected into drinking peer groups) were only observed among Victorian early adolescents. Findings were interpreted to suggest that Australian family and cultural norms that more commonly allow early adolescent alcohol use lead to a higher rate of peer selection., (© 2015 The Authors.

- Abstract
Objective: Our study examined the psychological outcomes associated with failed ART treatment outcomes in men and women., Search Strategy: A systematic search for studies published between January 1980 and August 2015 was performed across seven electronic databases., Inclusion Criteria: Studies were included if they contained data on psychosocial outcomes taken pre and post ART treatment., Data Extraction and Synthesis: A standardised form was used to extract data and was verified by two independent reviewers. Studies were meta-analysed to determine the association of depression and anxiety with ART treatment outcomes. Narrative synthesis identified factors to explain variations in the size and directions of effects and relationships explored within and between the studies., Main Results: Both depression and anxiety increased after a ART treatment failure with an overall pooled standardised mean difference (SMD) of 0.41 (95% CI: 0.27, 0.55) for depression and 0.21 (95% CI: 0.13, 0.29) for anxiety. In contrast, depression decreased after a successful treatment, SMD of -0.24 (95% CI: -0.37,-0.11). Both depression and anxiety decreased as time passed from ART procedure. Nonetheless, these remained higher than baseline measures in the group with the failed outcome even six months after the procedure. Studies included in the narrative synthesis also confirmed an association with negative psychological outcomes in relation to marital satisfaction and general well-being following treatment failure., Conclusion: Linking ART failure and psychosocial outcomes may elucidate the experience of treatment subgroups, influence deliberations around recommendations for resource allocation and health policy and guide patient and clinician decision making., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Adolescent depressed mood is related to the development of subsequent mental health problems, and family problems have been linked to adolescent depression. Longitudinal research on adolescent depressed mood is needed to establish the unique impact of family problems independent of other potential drivers. This study tested the extent to which family conflict exacerbates depressed mood during adolescence, independent of changes in depressed mood over time, academic performance, bullying victimization, negative cognitive style, and gender. Students (13 years old) participated in a three-wave bi-national study (n = 961 from the State of Washington, United States, n = 981 from Victoria, Australia; 98 % retention, 51 % female in each sample). The model was cross-lagged and controlled for the autocorrelation of depressed mood, negative cognitive style, academic failure, and bullying victimization. Family conflict partially predicted changes in depressed mood independent of changes in depressed mood over time and the other controls. There was also evidence that family conflict and adolescent depressed mood are reciprocally related over time. The findings were closely replicated across the two samples. The study identifies potential points of intervention to interrupt the progression of depressed mood in early to middle adolescence.

- Abstract
Purpose: The present study aims to examine risk factors and risk-based and interactive protective factors for violent offending in a group of 437 young Australians., Methods: Participants were recruited into the study when they were in Grade 5 (10-11 years) and followed up almost annually until young adulthood (18-19 years). Measures of violent offending, risk and protective factors, and demographics were obtained through a modification of the Communities That Care youth survey. The data collected enabled identification of groups of students at-risk of violent offending according to drug use, low family socioeconomic status, and antisocial behavior., Results: Results showed that there were very few associations between the risk factors and risk-based protective factors measured in this study (e.g., belief in the moral order, religiosity, peer recognition for prosocial involvement, attachment to parents, low commitment to school, and poor academic performance) and later self-reported violent offending. There were no statistically significant interactive protective factors., Conclusions: Further longitudinal analyses with large sample sizes are needed to examine risk factors and risk-based protective factors and interactive protective factors in at-risk groups. The findings support the need for multi-faceted prevention and early intervention approaches that target multiple aspects of youth's lives.

- Abstract
There is a growing body of evidence suggesting a link between sport participation and violent behavior outside of the sporting context. However, there have been few studies that have investigated the basis of this relationship. The current study examined longitudinal relationships between sport participation, problem alcohol use, and various violent behaviors, and whether sport participation moderates relationships between problem alcohol use and violence. The sample comprised 2,262 young adults (55% female, age range at Time 1 = 17-24 years) from Victoria, Australia, surveyed in 2010 and 2012. When controlling for common risk factors, substance use, and past violence, sport participation was not associated with any violent behaviors 2 years later. However, sport participation moderated the relationship between problem alcohol use and fighting, whereby problem alcohol use was associated with engaging in fights 2 years later for sport participants, but not for nonparticipants. These findings suggest that it is not sport participation per se that influences later violence but the drinking norms or culture embedded within certain sporting contexts. Prevention approaches that address the drinking culture and social approval of excessive alcohol consumption within sporting contexts may reduce the incidence of violent behavior in the community., (© The Author(s) 2015.)

- Abstract
There is instability in the developmental course of problem gambling [PG] over time; however, studies that examine PG at an aggregate level obscure these variations. The current study employed data from a longitudinal study of Australian young adults to investigate: 1) PG patterns (i.e., resistance, persistence, desistence, and new incidence); 2) prospective risk and protective factors for these patterns; and 3) behavioural outcomes associated with these patterns. A sample of 2261 young adults (55.73% female) from Victoria, Australia, who were part of the International Youth Development Study completed a survey in 2010 (T1, age 21) and 2012 (T2, age 23) measuring PG (two items based on established measures), risk and protective factors, and behavioural outcomes. The majority of the sample (91.69%) were resistors (no PG at T1 and T2), 3.62% were new incidence PG cases, 2.63% were desistors (PG at T1 but not T2), and 2.07% reported persistent PG at T1 and T2. Individual civic activism was protective of new incidence PG, while affiliation with antisocial peers and frequent alcohol use increased the risk of persistence. Persistent problem gamblers also experienced the greatest number of poor behavioural outcomes at T2. New incidence was associated with internalising symptoms at T2, while desistance was not associated with any behavioural outcomes. In conclusion, each PG pattern was associated with different predictors and outcomes, highlighting the need to consider variation in the course of young adult PG in order to provide efficacious prevention and intervention approaches, and to protect against relapse.

- Abstract
This study aimed to identify distinct developmental trajectories (sub-groups of individuals who showed similar longitudinal patterns) of cannabis use among Australian adolescents, and to examine associations between trajectory group membership and measures of social and behavioural adjustment in young adulthood. Participants (n=852, 53% female) were part of the International Youth Development Study. Latent class growth analysis was used to identify distinct trajectories of cannabis use frequency from average ages 12 to 19, across 6 waves of data. Logistic regression analyses and analyses of covariance were used to examine relationships between trajectory group membership and young adult (average age: 21) adjustment, controlling for a range of covariates. Three trajectories were identified: abstainers (62%), early onset users (11%), and late onset occasional users (27%). The early onset users showed a higher frequency of antisocial behaviour, violence, cannabis use, cannabis-related harms, cigarette use, and alcohol harms, compared to the abstinent group in young adulthood. The late onset occasional users reported a higher frequency of cannabis use, cannabis-related harms, illicit drug use, and alcohol harms, compared to the abstinent group in young adulthood. There were no differences between the trajectory groups on measures of employment, school completion, post-secondary education, income, depression/anxiety, or alcohol use problems. In conclusion, early onset of cannabis use, even at relatively low frequency during adolescence, is associated with poorer adjustment in young adulthood. Prevention and intervention efforts to delay or prevent uptake of cannabis use should be particularly focussed on early adolescence prior to age 12., (Copyright © 2015 Elsevier Ltd.

- Abstract
Bullying is a prevalent problem in schools that is associated with a number of negative outcomes for both the child who bullies and his or her victims. In a community sample of 284 ethnically diverse school-children (54.2 % girls) between the ages of 9 and 14 years (M = 11.28, SD = 1.82), the current study examined whether the level of victimization moderated the association between bullying and several behavioral, social, and emotional characteristics. These characteristics were specifically chosen to integrate research on distinct developmental pathways to conduct problems with research on the characteristics shown by children who bully others. Results indicated that both bullying and victimization were independently associated with conduct problems. However, there was an interaction between bullying and victimization in the prediction of callous-unemotional (CU) traits, such that the association between bullying and CU traits was stronger for those lower on victimization. Further, bullying was positively associated with positive attitudes towards bullying and anger expression and neither of these associations were moderated by the level of victimization. In contrast, bullying was not associated with the child's perceived problems regulating anger, suggesting that children with higher levels of bullying admit to expressing anger but consider this emotional expression as being under their control.

- Abstract
Purpose: There have been few longitudinal studies of deliberate self-harm (DSH) in adolescents. This cross-national longitudinal study outlines risk and protective factors for DSH incidence and persistence., Methods: Seventh and ninth grade students (average ages 13 and 15 years) were recruited as state-representative cohorts, surveyed, and then followed up 12 months later (N = 3,876), using the same methods in Washington State and Victoria, Australia. The retention rate was 99% in both states at follow-up. A range of risk and protective factors for DSH were examined using multivariate analyses., Results: The prevalence of DSH in the past year was 1.53% in Grade 7 and .91% in Grade 9 for males and 4.12% and 1.34% for Grade 7 and Grade 9 females, respectively, with similar rates across states. In multivariate analyses, incident DSH was lower in Washington State (odds ratio [OR] = .67; 95% confidence interval [CI] = .45-1.00) relative to Victoria 12 months later. Risk factors for incident DSH included being female (OR = 1.93; CI = 1.35-2.76), high depressive symptoms (OR = 3.52; CI = 2.37-5.21), antisocial behavior (OR = 2.42; CI = 1.46-4.00), and lifetime (OR = 1.85; CI = 1.11-3.08) and past month (OR = 2.70; CI = 1.57-4.64) alcohol use relative to never using alcohol., Conclusions: Much self-harm in adolescents resolves over the course of 12 months. Young people who self-harm have high rates of other health risk behaviors associated with family and peer risks that may all be targets for preventive intervention., (Copyright © 2015 Society for Adolescent Health and Medicine.

- Abstract
The purpose of the present article is to compare the individual, peer, family, and school risk and protective factors for both traditional and cyber-bullying victimization. This article draws on data from 673 students from Victoria, Australia, to examine Grade 7 (aged 12-13 years) predictors of traditional and cyber-bullying victimization in Grade 9 (aged 14-15 years). Participants completed a modified version of the Communities That Care youth survey. There were few similarities and important differences in the predictors of traditional and cyber-bullying victimization. For Grade 9 cyber-bullying victimization, in the fully adjusted model, having been a victim of traditional bullying in Grade 7 and emotional control in Grade 7 were predictors. For Grade 9 traditional bullying victimization, predictors were Grade 7 traditional bullying victimization, association with antisocial peers, and family conflict, with family attachment and emotional control marginally statistically significant. The use of evidence-based bullying prevention programs is supported to reduce experiences of both traditional and cyber-bullying victimization, as is the implementation of programs to assist students to regulate their emotions effectively. In addition, traditional bullying victimization may be reduced by addressing association with antisocial friends, family conflict, and bonding to families., (© The Author(s) 2014.)

- Abstract
In an influential 2002 paper, Farrington and colleagues argued that to understand 'causes' of delinquency, within-individual analyses of longitudinal data are required (compared to the vast majority of analyses that have focused on between-individual differences). The current paper aimed to complete similar analyses to those conducted by Farrington and colleagues by focusing on the developmental correlates and risk factors for antisocial behaviour and by comparing within-individual and between-individual predictors of antisocial behaviour using data from the youngest Victorian cohort of the International Youth Development Study, a state-wide representative sample of 927 students from Victoria, Australia. Data analysed in the current paper are from participants in Year 6 (age 11-12 years) in 2003 to Year 11 (age 16-17 years) in 2008 ( N = 791; 85% retention) with data collected almost annually. Participants completed a self-report survey of risk and protective factors and antisocial behaviour. Complete data were available for 563 participants. The results of this study showed all but one of the forward- (family conflict) and backward-lagged (low attachment to parents) correlations were statistically significant for the within-individual analyses compared with all analyses being statistically significant for the between-individual analyses. In general, between-individual correlations were greater in magnitude than within-individual correlations. Given that forward-lagged within-individual correlations provide more salient measures of causes of delinquency, it is important that longitudinal studies with multi-wave data analyse and report their data using both between-individual and within-individual correlations to inform current prevention and early intervention programs seeking to reduce rates of antisocial behaviour.

- Abstract
Introduction: Comorbidity between problem gambling and internalising disorders (anxiety and depression) has long been recognised. However, it is not clear how these relationships develop, and what factors can foster resilience to both conditions. The current study draws on longitudinal cohort data to investigate: 1) the cross-sectional and longitudinal relationships between problem gambling and internalising symptoms; 2) whether there are common and/or specific social environmental factors protective against both internalising symptoms and problem gambling in young adulthood; and 3) interactive protective factors (i.e., those that moderate the relationship between problem gambling and internalising symptoms)., Methods: A sample of 2248 young adults (55% female) completed a survey in 2010 (T1) and 2012 (T2) which assessed problem gambling (measured via two items based on established measures), internalising symptoms, and social environmental protective factors., Results: A positive cross-sectional relationship between problem gambling and internalising symptoms was found; however, there was no statistically significant longitudinal relationship between the two conditions. Protective factors for internalising symptoms were observed within the domains of the community, family and peer group; however, there were no statistically significant protective factors identified for problem gambling., Conclusions: These findings demonstrate that the social environmental protective factors for adult internalising symptoms assessed in the present study are poor longitudinal predictors of young adult problem gambling. Given the lack of common protective factors, it may be necessary to focus on separate factors to protect against each condition, if we are to address the comorbidity between problem gambling and internalising symptoms., (Copyright © 2015.

- Abstract
Aims: Failure to complete high school predicts substantial economic and social disadvantage in adult life. The aim of this study was to determine the longitudinal association of mid-adolescent polydrug use and high school non-completion, relative to other drug use profiles., Design: A longitudinal analysis of the relationship between polydrug use in three cohorts at grade 9 (age 14-15 years) and school non-completion (reported post-high school)., Setting: A State-representative sample of students across Victoria, Australia., Participants: A total of 2287 secondary school students from 152 high schools. The retention rate was 85%., Measurements: The primary outcome was non-completion of grade 12 (assessed at age 19-23 years). At grade 9, predictors included 30-day use of eight drugs, school commitment, academic failure and peer drug use. Other controls included socio-economic status, family relationship quality, depressive symptoms, gender, age and cohort., Findings: Three distinct classes of drug use were identified-no drug use (31.7%), mainly alcohol use (61.8%) and polydrug use (6.5%). Polydrug users were characterized by high rates of alcohol, tobacco and cannabis use. In the full model, mainly alcohol users and polydrug users were less likely to complete school than non-drug users [odds ratio (OR) = 1.54, 95% confidence interval (CI) = 1.17-2.03) and OR = 2.51, 95% CI = 1.45-4.33), respectively, P < 0.001]. These effects were independent of school commitment, academic failure, peer drug use and other controls., Conclusions: Mid-adolescent polydrug use in Australia predicts subsequent school non-completion after accounting for a range of potential confounding factors. Adolescents who mainly consume alcohol are also at elevated risk of school non-completion., (© 2015 Society for the Study of Addiction.)

- Abstract
Objectives: To investigate associations between Grade 9 and 10 cyber-bullying perpetration and victimization and Grade 11 problem behavior and mental health problems after controlling for risk factors for these outcomes in the analyses., Methods: The sample comprised 927 students from Victoria, Australia who completed a modified version of the self-report Communities That Care Youth Survey in Grades 9-11 to report on risk factors, traditional and cyber-bullying perpetration and victimization, problem behavior, and mental health. Complete data on over 650 participants were analyzed., Results: Five per cent of Grade 9 and 10 students reported cyber-bullying perpetration only, 6-8% reported victimization only, and 8-9% both cyber-bullied others and were cyber-bullied. Results showed that cyber-bullying others in Grade 10 was associated with theft in Grade 11, cyber-victimization in Grade 10 was linked with Grade 11 depressive symptoms, and Grade 10 cyber-bullying perpetration and victimization combined predicted Grade 11 school suspension and binge drinking., Conclusions: Prevention approaches that target traditional and cyber-bullying, and established risk factors are necessary. Such multi-faceted programs may also reduce problem behavior and mental health problems.

- Abstract
Homeless youth commonly report engaging in sexual risk behaviors. These vulnerable young people also frequently report being sexually victimized. This systematic review collates, summarizes, and appraises published studies of youth investigating relationships between homelessness, perpetration of sexual offenses, experience of sexual victimization, and engagement in sexual risk behavior. A systematic search of seventeen psychology, health, and social science electronic databases was conducted. Search terms included "homeless*," "youth," "offend*," "victimization," "crime," "rape," "victim*," and "sex crimes." Thirty-eight studies were identified that met the inclusion criteria. Findings showed homeless youth commonly report being raped and sexually assaulted, fear being sexually victimized, and engage in street prostitution and survival sex. Rates of victimization and sexual risk behavior were generally higher for females. Given the paucity of longitudinal studies and limitations of current studies, it is unclear whether homelessness is prospectively associated with sexual victimization or engagement in sexual risk behavior, and whether such associations vary cross nationally and as a function of time and place. Future prospective research examining the influence of the situational context of homelessness is necessary to develop a better understanding of how homelessness influences the perpetration of sexual offenses, experience of sexual victimization, and engagement in sexual risk behavior among homeless youth.

- Abstract
Background: This article examines the effect of early adolescent alcohol use on mid-adolescent school suspension, truancy, commitment, and academic failure in Washington State, United States, and Victoria, Australia. Also of interest was whether associations remain after statistically controlling for other factors known to predict school outcomes., Methods: State-representative student samples were surveyed in 2002 (grade 7; N = 1858) and followed up annually to 2004 (grade 9) in both sites. Students completed a modified version of the Communities That Care survey to report alcohol use, school outcomes, and risk and protective factors. Response rates were above 74% and retention rates exceeded 98% in both places., Results: Controlling for grade 7 risk factors, grade 7 current alcohol use, and heavy episodic drinking were associated with grade 8 school suspension. Grade 7 current and frequent alcohol use and heavy episodic drinking were linked to grade 9 truancy. In fully adjusted analyses, associations between early alcohol use and academic failure and low school commitment did not remain., Conclusions: Although alcohol use is one factor influencing school performance and connection, there are other risk factors that need to be targeted to improve school outcomes., (© 2014, American School Health Association.)

- Abstract
Purpose: The purpose of the current article was to examine the adolescent risk and protective factors (at the individual, peer group, and family level) for young adult cyberbullying perpetration and victimization., Methods: Data from 2006 (Grade 9) to 2010 (young adulthood) were analyzed from a community sample of 927 Victorian students originally recruited as a statewide representative sample in Grade 5 (age, 10-11 years) in 2002 and followed-up to age 18-19 years in 2010 (N = 809). Participants completed a self-report survey on adolescent risk and protective factors and traditional and cyberbullying perpetration and victimization and young adult cyberbullying perpetration and victimization., Results: As young adults, 5.1% self-reported cyberbullying perpetration only, 5.0% reported cyberbullying victimization only, and 9.5% reported both cyberbullying perpetration and victimization. In fully adjusted logistic regression analyses, the adolescent predictors of cyberbullying perpetration only were traditional bullying perpetration, traditional bullying perpetration and victimization, and poor family management. For young adulthood cyberbullying victimization only, the adolescent predictor was emotion control. The adolescent predictors for young adult cyberbullying perpetration and victimization were traditional bullying perpetration and cyberbullying perpetration and victimization., Conclusions: Based on the results of this study, possible targets for prevention and early intervention are reducing adolescent involvement in (traditional or cyber) bullying through the development of social skills and conflict resolution skills. In addition, another important prevention target is to support families with adolescents to ensure that they set clear rules and monitor adolescents' behavior. Universal programs that assist adolescents to develop skills in emotion control are warranted., (Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

- Abstract
Identifying specific aspects of peer social norms that influence adolescent substance use may assist international prevention efforts. This study examines two aggregated measures of social norms in the school setting and their predictive association with substance (alcohol, tobacco and marijuana) use 2 years later in a large cross-national population-based cohort of adolescents. The primary hypothesis is that in Grade 7 both "injunctive" school norms (where students associate substance use with "coolness") and "descriptive" norms (where student substance use is common) will predict Grade 9 substance use. Data come from the International Youth Development Study, including 2,248 students (51.2% female) in the US and Australia attending 121 schools in Grade 7. Independent variables included injunctive norms (aggregating measures of school-wide coolness ratings of each substance use) and descriptive norms (aggregating the prevalence of school substance use) in Grade 7. Dependent variables included binge drinking and current use of alcohol, tobacco and marijuana in Grade 9. Associations between each type of school-wide social norm and substance use behaviors in Grade 9 were tested using multilevel logistic regression, adjusting for covariates. In unadjusted models, both injunctive and descriptive norms each significantly predicted subsequent substance use. In fully adjusted models, injunctive norms were no longer significantly associated with Grade 9 use, but descriptive norms remained significantly associated with tobacco and marijuana use in the expected direction. The findings identify descriptive social norms in the school context as a particularly important area to address in adolescent substance use prevention efforts.

- Abstract
The effect of early adolescent alcohol use on antisocial behavior was examined at one- and two-year follow-up in Washington, United States and Victoria, Australia. Each state used the same methods to survey statewide representative samples of students (N = 1,858, 52% female) in 2002 (Grade 7 [G7]), 2003 (Grade 8 [G8]), and 2004 (Grade 9 [G9]). Rates of lifetime, current, frequent, and heavy episodic alcohol use were higher in Victoria than Washington State, whereas rates of five antisocial behaviors were generally comparable across states. After controlling for established risk factors, few associations between alcohol use and antisocial behavior remained, except that G7 current use predicted G8 police arrests and stealing and G9 carrying a weapon and stealing; G7 heavy episodic use predicted G8 and G9 police arrests; and G7 lifetime use predicted G9 carrying a weapon. Hence, risk factors other than alcohol were stronger predictors of antisocial behaviors.
