Delinquency, School Context, and Risk Factors in India, Australia, and the United States: Implications for Prevention.

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.

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.

Reciprocal associations between early adolescent antisocial behavior and depressive symptoms: A longitudinal study in Victoria, Australia and Washington State, United States.

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.

Longitudinal, reciprocal relationships between family management and antisocial peer associations.

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.

myTREEHOUSE Self-Concept Assessment: preliminary psychometric analysis of a new self-concept assessment for children with cerebral palsy.

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.

Influence of Early Onset of Alcohol Use on the Development of Adolescent Alcohol Problems: a Longitudinal Binational Study.

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.

Peer Group Patterns of Alcohol-Using Behaviors Among Early Adolescents in Victoria, Australia, and Washington State, United States.

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.

Depressed Mood During Early to Middle Adolescence: A Bi-national Longitudinal Study of the Unique Impact of Family Conflict.

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.

Risk Factors and Risk-Based Protective Factors for Violent Offending: A Study of Young Victorians.

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.

Associations between youth homelessness, sexual offenses, sexual victimization, and sexual risk behaviors: a systematic literature review.

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.

Within-individual versus between-individual predictors of antisocial behaviour: A longitudinal study of young people in Victoria, Australia.

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.

A prospective study of adolescent risk and protective factors for problem gambling among young adults.

There is a paucity of research examining prospective predictors of problem gambling. The current study utilised a large longitudinal data set (N = 2328) to examine a large range of adolescent risk and protective factors for problem gambling in young adulthood. These risk and protective factors covered the domains of the community, family, school, peer group and individual. Numerous predictors associated with the family, school and peer-individual were statistically significant in analyses adjusted for gender and age. However, in the fully adjusted multivariate analyses, only two predictors were statistically significant. Within this model, gender (female) was associated with a reduced risk of young adult problem gambling, while family rewards for prosocial involvement moderated the risk relationship between adolescent alcohol use and young adult problem gambling. These findings highlight the importance of adolescent alcohol use and family environment as potentially modifiable predictors of young adult problem gambling.

Social norms in the development of adolescent substance use: a longitudinal analysis of the International Youth Development Study.

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.

Reassessing the Effects of Early Adolescent Alcohol Use on Later Antisocial Behavior: A Longitudinal Study of Students in Victoria, Australia and Washington State, United States.

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.

Students' experiences of school suspension.

ISSUE ADDRESSED: School inclusion and academic attainment are key social determinants of health. Students who have been suspended from school are more likely to disengage from school and consequently not receive the health promoting benefits of social inclusion and academic achievement. This study sought to explore the experiences of students who have been previously suspended (i.e. had experienced school exclusion). METHODS: Seventy-four previously suspended adolescents from five schools in the state of Victoria, Australia, completed a written questionnaire. Students reported their understanding of the process of being suspended; what they did and with whom they spent the day(s) of suspension; and their perceptions of their return to school post-suspension. RESULTS: While suspended, a minority of suspended students received adult supervision and most suspended students participated in benign leisure activities. Upon return to school, students reported diminished teacher assistance and found that suspension did not help resolve the underlying issues that lead to the suspension. CONCLUSIONS: Removal of a student displaying problem behaviours from the classroom may provide temporary relief to the school community but suspended students report minimal benefits from suspension. Suspension removes the potential pro-social normative influences of school and provides an opportunity to establish antisocial peer networks. Suspended students appear to perceive a stigma upon their return to school, further diminishing an already tenuous school relationship. So what? School suspension exposes disadvantaged students to several negative social determinants of health. Students displaying problem behaviours would benefit from interventions that maintain the student's relationship with school. Should suspension be necessary, schools could assist by ensuring that suspended students receive appropriate adult supervision and a formal reintegration to school to promote social inclusion and academic attainment, two recognised key determinants of health.

Carrying weapons and intent to harm among Victorian secondary school students in 1999 and 2009.

OBJECTIVE: To examine comparable survey data across 10 years to assess whether rates of self-reported weapon carrying and intent to harm others have increased as suggested in reported trends in violent offences. DESIGN, SETTING AND PARTICIPANTS: Population-based surveys administered to Victorian secondary school students in 1999 (8984 students) and 2009 (10 273 students) attending government, Catholic and independent schools. MAIN OUTCOME MEASURES: Student self-reports of carrying a weapon and attacking someone with the intent to harm in the past 12 months. RESULTS: In both surveys, about 15.0% of students reported carrying a weapon and about 7.0% reported attacking someone with intent to harm in the past 12 months, with higher rates among boys than girls. There was no change over time in the rates of students carrying weapons or attacking someone with the intent to harm, after controlling for demographic variables. CONCLUSIONS: In contrast to media portrayals and reported trends in violent offences, rates of students carrying weapons and attacking others with intent to harm have not changed between 1999 and 2009. These findings underline the importance of having national population-based data to regularly monitor the rates of these and related behaviours among young Australians.

Cannabis use and related harms in the transition to young adulthood: a longitudinal study of Australian secondary school students.

The current study documents the changing rates of cannabis use, misuse and cannabis-related social harms among Australian adolescents as they grow into young adulthood. It utilised data from a longitudinal study of young people at ages 15, 16, 17, and 19. The rates of cannabis use were found to increase as participants aged; past year use increased from 7.5% at age 15 to 29.8% at age 19. Further, at ages 17 and 19, cannabis use was more prevalent among males than females. Among those who reported cannabis use, the rates of cannabis-related harms were low to moderate, and did not increase with age in the same manner as rates of cannabis use. The most prevalent self-reported cannabis-related harm was anxiety/depression; affecting between 20-30% of the cannabis users at each age. These findings may assist in understanding the extent of cannabis-related problems among youth, and in planning relevant services.

A longitudinal study of the reciprocal effects of alcohol use and interpersonal violence among Australian young people.

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.

Does school suspension affect subsequent youth nonviolent antisocial behavior? A longitudinal study of students in Victoria, Australia and Washington State, United States.

School suspension has been not only associated with negative behaviours but is predictive of future poor outcomes. The current study investigates a) whether school suspension is a unique predictor of youth nonviolent antisocial behaviour (NVAB) relative to other established predictors, and b) whether the predictors of NVAB are similar in Australia and the United States (U.S.). The data analysed here draws on two state-wide representative samples of Grade 7 and 9 students in Victoria, Australia and Washington State, U.S., resurveyed at 12-month follow-up (N = 3,677, 99% retention). School suspension did not uniquely predict NVAB in the final model. The predictors of NVAB, similar across states, included previous student NVAB; current alcohol and tobacco use; poor family management; association with antisocial friends; and low commitment to school. An implication of the findings is that U.S. evidence-based prevention programs targeting the influences investigated here could be trialled in Australia.

Longitudinal consequences of adolescent bullying perpetration and victimisation: a study of students in Victoria, Australia.

AIMS: To examine the associations between self-reported bullying perpetration and victimisation in Years 7 and 10 and a range of psychosocial outcomes in Year 11. METHOD: This analysis draws on data from the International Youth Development Study, a longitudinal study of 5769 students from Victoria, Australia and Washington State, United States who were recruited through schools in Years 5, 7 and 9 in 2002. Data for the current results are taken from participants in the youngest (Year 5) Victorian cohort of the study. RESULTS: Rates of bullying victimisation exceeded 30% and up to one in five students had engaged in bullying. Adjusted logistic regression analyses revealed that bullying perpetration, and bullying victimisation in Year 7 did not significantly predict psychosocial outcomes in Year 11. Bullying perpetration in Year 10 was associated with an increased likelihood of theft, violent behaviour and binge drinking. Year 10 bullying victimisation was associated with an increased likelihood of Year 11 depressive symptoms. CONCLUSIONS: Prevention approaches that target bullying perpetration and victimisation are necessary. Programmes that lessen bullying may also have an impact on other proximally related behaviours, including binge drinking and depression.
