Impact of community-based employment on Aboriginal and Torres Strait Islander wellbeing, aspirations, and resilience.

BACKGROUND: This study evaluated a research project that provided employment in an Aboriginal and Torres Strait Islander community-based setting and supported participants to identify and achieve their goals and aspirations. The evaluation examined changes in personal, relationship, community and cultural strengths and resources and explored empowerment and resilience, in terms of promoting wellbeing. METHODS: Ten Aboriginal people employed as life coaches and peer researchers participated in semi-structured interviews and also completed the Aboriginal Resilience and Recovery Questionnaire at the beginning of their employment and 6-months after employment. Interviews with the 10 participants explored changes in their wellbeing, relationships, resilience, opportunity to lead, aspirations, goal setting skills, connection to culture and community, and empowerment. RESULTS: Participants personal strengths, and cultural and community strengths, sub-scale scores showed improvements across the 6-month period, however these changes were not statistically significant. Using reflexive thematic analysis, we generated five themes including Aspirations; Personal capabilities; Constraints to wellbeing; Community engagement and cultural connection; and Employment facilitators. Overall, participants identified that despite the challenges of their work and the additional challenges posed by the COVID-19 lockdowns, they were able to develop their skills to set and achieve goals. They reported feeling empowered and proud of their work, and engaged more frequently with their communities and culture. CONCLUSIONS: The study outcomes evidence the role of employment in an Aboriginal and Torres Strait Islander community-based project in strengthening wellbeing, enhancing resilience, and supporting participants to advance their personal goals and aspirations. These findings reinforce the importance of supporting the aspirations and employment of Aboriginal and Torres Strait Islander Peoples through employment.

Does adolescent depression modify the association between psychosocial job stressors and mental health in emergent adulthood?

BACKGROUND: Job stressors can be particularly harmful to the mental health of disadvantaged groups through differential exposure, differential sensitivity to the effects of exposure, or both. In this paper, we assess the extent to which emergent adult workers with an adolescent history of high depression symptoms may be differentially sensitive to the effect of job stressors on mental health. METHODS: We conducted a secondary analysis of three waves of the Australian arm of the International Youth Development Study (n = 1262). We used multivariable linear regression to assess whether self-reported measures of high depression symptoms at one or two time points in adolescence (ages 11-16 years) modified the cross-sectional association between four self-reported job stressors (job demands, job control, job strain, and incivility at work) and psychological distress (Kessler-10 scores) in emergent adulthood (ages 23-27 years). RESULTS: For all four job stressors, there was a consistent pattern of approximately a doubling in the magnitude of association for participants with a history of high depression symptoms at two points in adolescence compared with those with no history of depression. However, results of effect modification analysisfor only job demands and job strain excluded chance as a potential explanation. CONCLUSIONS: Findings showed partial support for the hypothesis that a history of high depression symptoms in adolescence predicts stronger associations between job stressor exposures and psychological distress among those employed in emergent adulthood. The limitations of this secondary analysis suggest a need for purpose-designed studies to answer this important research question more definitively.

Predicting the Trajectories of Parents' Relationship Well-Being During COVID-19 Lockdowns and Beyond: a Vulnerability, Stress and Adaptation Model Perspective.

Strict lockdowns have been employed by many of the world's nations as a public health response to COVID-19. However, concerns have been expressed as to how such public health responses disturb the human ecosystem. In this paper, we report on findings from a longitudinal study of Australian parents in which we investigated how state differences in government-mandated lockdowns affect the relationship well-being (i.e., relationship satisfaction and loneliness) of parents. We situated the study of the relational effects of strict lockdowns within the Vulnerability Stress Adaptation Model (VSAM, Karney & Bradbury, 1995) that considers the role of parents' pre-existing vulnerabilities (i.e., psychological distress and attachment insecurity), life stressors (pre-pandemic and COVID-19 stressors), and adaptive relationship processes (constructive communication and perceived partner support). A total of 1942 parents completed 14 waves of assessments of relationship satisfaction and loneliness over a 13.5-month period as well as baseline assessments of personal vulnerabilities, life stressors, and adaptive relationship processes. Parents with high relationship adaptations and low vulnerabilities evidenced the highest relationship well-being (i.e., high satisfaction and low loneliness) during changes in lockdown restrictions, while parents with moderate relationship adaptations and vulnerabilities experienced the poorest well-being. Differences in state lockdown restrictions (i.e., Victoria [long and strict lockdown policy] vs all other states) were associated with differences in relationship well-being for parents with high relationship adaptations. Specifically, Victorian parents experienced significant declines in relationship well-being compared to non-Victorian parents. Our findings provide novel insights into how government-mandated social restrictions can disrupt the relational ecology of parents.

Health and Social Vulnerabilities Among Unstably Housed and Homeless Young Adults During the COVID-19 Pandemic.

The role of housing as a social driver of health is well-established, with stable housing being an important factor in reducing health inequities. During developmentally critical periods such as young adulthood, unstable housing and related social marginalization have profound effects on development and later health, social, and economic wellbeing. This exploratory study analyzed data from a population-based, longitudinal sample of young adults (average age 31 years) from Washington State (n = 755) to compare health and economic impacts of the early days of the COVID-19 pandemic, with a focus on housing status. Descriptive results suggest the pandemic exposed underlying vulnerabilities for young adults experiencing homelessness and housing instability, with an overall widening of inequities related to financial difficulties and increased risk for poor mental health and social isolation. Findings suggest that these vulnerabilities are magnified in the context of public health crises and strengthen the case for population-based studies investigating potential modifiable causes of housing instability to inform prevention and early intervention at the earliest possible point in a young person's development. Studies examining the severity of COVID-related hardships on young adult health and social outcomes are vital for establishing an evidence base for strategic policy action that seeks to prevent a rebound in young adult homelessness and housing instability post-pandemic. These studies would bolster both emergency preparedness responses that account for the unique needs of vulnerable populations and upstream population-level prevention approaches beginning long before the imminent risk for housing instability develops.

Program logic of a service collaboration to support parents with intellectual disability.

BACKGROUND: This article describes the Steps to Confident Parenting (SCP) program, developed by an Australian family service consortium. The SCP integrates home-based and case-management services to enhance the skills of parents with a diagnosed or suspected intellectual disability/cognitive impairment and to prevent child protection interventions. METHOD: 'Program explication' methodology documented the components/activities, and underpinning evidence for this practitioner designed service through interviews with nine agency staff. A literature review evaluated evidence for the implicit program benefit theory. RESULTS AND CONCLUSION: The SCP comprised five logically consistent components-Targeted Referral, Assessments, Initial Consultation, Program Delivery, Closure and Follow-up. Components generally had 'some' supportive evidence, however there was a 'lack of' evidence for Closure and Follow-up. In the context of a partnership seeking to build the evidence for the SCP, it was recommended that a protocol for a randomised trial evaluation with longer term follow-up be drafted by the consortia.

The role of adolescent social inclusion in educational attainment among vulnerable youth.

BACKGROUND: Completing high school enables access to educational and employment opportunities associated with better physical and mental health and improved quality of life. Identifying modifiable factors that promote optimal educational trajectories for youth experiencing disadvantage is an important research focus. Social inclusion has been theorised to play a role in promoting better educational outcomes for this priority population, however limited research has examined this relationship. METHOD: This study used three waves of data from the state-representative Australian arm of the International Youth Development Study (IYDS) (youngest cohort, N = 733; 54% female, 95% Australian born) to examine the extent to which vulnerability in primary school (Grade 5; Mage = 10.97, SD = 0.38) and social inclusion in mid-adolescence (Year 10; Mage = 15.50, SD = 0.53), were associated with school completion in young adulthood (post-secondary; Mage = 19.02, SD = 0.43). RESULTS: Regression models identified an interaction between social inclusion and vulnerability (OR = 1.37, 95% CI [1.06, 1.77], p = .016), indicating that the association between vulnerability and school completion varied as a student's level of social inclusion increased. Higher social inclusion was beneficial for youth with lower levels of vulnerability but did not appear to influence school completion for the most vulnerable students. CONCLUSIONS: For many young people, promoting social inclusion may support engagement in education and play a protective role. However, further research is needed to better understand the role of social inclusion for highly vulnerable youth, particularly the mechanisms via which social inclusion may have differential effects on school completion.

Uncovering the advertising and promotional strategies of tobacco companies in Cambodia: recall of below-the-line marketing among young male smokers.

INTRODUCTION: Tobacco companies have used below-the-line marketing in novel ways to promote their brands to youth in low/middle-income countries in Southeast Asia. This study explores how young male smokers in Cambodia experience below-the-line marketing strategies. METHODS: Convenience sampling was used to recruit 147 young male smokers (18-24 years) in Cambodia in early 2020. Local research assistants conducted mixed-methods interviews with participants in Khmer or English. Participants recalled exposure to below-the-line marketing strategies and provided in-depth descriptions about their experiences with individual sales promotions. Quantitative data were analysed using descriptive statistics and qualitative data were analysed using thematic analysis. RESULTS: 54% of participants recalled exposure to at least one below-the-line marketing strategy, including point-of-sale promotions (32.7%), individual sales promotions (27.9%) and online advertising (14.3%). Participants described individual sales promotions in public settings, and recalled that promoters were mostly female, attractive and targeted young males. Tactics used to encourage young people to accept promotional offers included free cigarettes and sample packets, swapping current cigarettes for new brands and collecting consumer details after interviewing. The brands and product features of cigarettes being promoted were readily described by participants. CONCLUSION: This study provides evidence that illegal below-the-line marketing is still occurring in Cambodia, and increased monitoring and enforcement of advertising restrictions is needed.

Policies are Needed to Increase the Reach and Impact of Evidence-Based Parenting Supports: A Call for a Population-Based Approach to Supporting Parents, Children, and Families.

Parents can be essential change-agents in their children's lives. To support parents in their parenting role, a range of programs have been developed and evaluated. In this paper, we provide an overview of the evidence for the effectiveness of parenting interventions for parents and children across a range of outcomes, including child and adolescent mental and physical health, child and adolescent competencies and academic outcomes, parental skills and competencies, parental wellbeing and mental health, and prevention of child maltreatment and family violence. Although there is extensive research showing the effectiveness of evidence-based parenting programs, these are not yet widely available at a population level and many parents are unable to access support. We outline how to achieve increased reach of evidence-based parenting supports, highlighting the policy imperative to adequately support the use of these supports as a way to address high priority mental health, physical health, and social problems.

Modeling Adolescent Social Inclusion to Improve School Completion.

Enhancing social inclusion in young people could increase engagement in education, yet few longitudinal studies have examined this relationship. This study aimed to identify whether social inclusion in an Australian adolescent sample predicted high school completion three years later. Using state-representative data from the International Youth Development Study, two waves of the youngest cohort (51.6% female and 94.6% Australian born) during mid-adolescence (n = 825, Mage = 15.99, SD = 0.39) and post-secondary school (n = 809, Mage = 19.03, SD = 0.44) were analyzed. Factor analysis identified a 4-factor structure that represented an overarching social inclusion construct: (1) Citizenship, (2) Connectedness to Community, (3) Connectedness to Family, and (4) Connectedness to and Participation in School. Multivariate regression analyses indicated higher social inclusion levels in mid-adolescence predicted an increased likelihood of high school completion three years later. The implementation of strategies that incorporate the enhancement of social inclusion may improve educational outcomes for young people.

Sexting Among Australian Adolescents: Risk and Protective Factors.

Although consensual sending of sexts between adolescents is considered developmentally appropriate, it may also entail a range of negative consequences. Current sexting research lacks a comprehensive theoretical framework identifying a range of risk and protective factors underpinning adolescent consensual sending of sexts across individual, interpersonal, and distal levels. Further, there is a lack of systematic evaluation of how the importance of these factors may vary across adolescent age. This study investigated the utility of the Social Development Model to predict a range of risk and protective factors across individual, family, peer, school, and community-level factors. The sample included 1302 teenagers from Victoria, Australia (Mage = 14.54, SD = 1.14, 50.8% girls). Results indicated that 146 (11.7%) participants sent a sext (76 boys and 70 girls). Logistic regression analyses revealed that the Social Development Model accounted for 45.8% of variance in sexting, with greater likelihood of sending sexts being associated with older age, prior sexual activity, school sector, physical activity, lifetime substance use, greater depressive symptoms, sensation seeking, and perceived substance availability in the community. Multigroup analyses revealed that lifetime substance use was associated with a greater likelihood of sending sexts among younger teens. Among older adolescents, adaptive coping was associated with reduced engagement in sexting, while higher parental overcontrol and family conflict increased the odds of sending sexts. Overall, sexting is associated with a range of modifiable factors potentially amenable to intervention.

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

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

Parent and child mental health trajectories April 2020 to May 2021: Strict lockdown versus no lockdown in Australia.

OBJECTIVE: To control a second-wave COVID-19 outbreak, the state of Victoria in Australia experienced one of the world's first long and strict lockdowns over July-October 2020, while the rest of Australia experienced 'COVID-normal' with minimal restrictions. We (1) investigate trajectories of parent/child mental health outcomes in Victoria vs non-Victoria and (2) identify baseline demographic, individual and COVID-19-related factors associated with mental health trajectories. METHODS: Online community sample of 2004 Australian parents with rapid repeated assessment over 14 time-points over April 2020 to May 2021. Measures assessed parent mental health (Depression, Anxiety and Stress Scales-21), child depression symptoms (13-item Short Mood and Feelings Questionnaire) and child anxiety symptoms (four items from Brief Spence Children's Anxiety Scale). RESULTS: Mental health trajectories shadowed COVID-19 infection rates. Victorians reported a peak in mental health symptoms at the time of the second-wave lockdown compared to other states. Key baseline predictors, including parent and child loneliness (standardized regression coefficient [ß] = 0.09-0.46), parent/child diagnoses (ß = 0.07-0.21), couple conflict (ß = 0.07-0.18) and COVID-19 stressors, such as worry/concern about COVID-19, illness and loss of job (ß = 0.12-0.15), predicted elevated trajectories. Effects of predictors on parent and child mental health trajectories are illustrated in an online interactive app for readers (https://lingtax.shinyapps.io/CPAS_trend/). CONCLUSION: Our findings provide evidence of worse trajectories of parent and child mental health symptoms at a time coinciding with a second COVID-19 outbreak involving strict lockdown in Victoria, compared to non-locked states in Australia. We identified several baseline factors that may be useful in detecting high-risk families who are likely to require additional support early on in future lockdowns.

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

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

Adolescent Antecedents of Young Adult Homelessness: a Cross-national Path Analysis.

Adolescent and young adult health, development, and behavior lay a foundation for future population health. Increasing rates of young adult homelessness mean there is a need for research which generates evidence to support a stronger focus on population-level prevention. Using longitudinal data from a population-based sample of young adults participating in the cross-nationally matched International Youth Development Study, we examined adolescent antecedents of young adult homelessness in Washington State in the USA and in Victoria, Australia. Participants were surveyed using a modified version of the Communities That Care youth survey. Analyses of prospective, longitudinal data from 1945 participants, recruited as state-representative secondary school samples at grade 7 (average age 13, 2002) and longitudinally compared at young adulthood (average age 25, 2014), showed that young adults in Washington State reported higher rates of past year homelessness (5.24%) compared to those in Victoria (3.25%). Path modeling showed less positive family management strategies at age 13 uniquely increased risk for age 25 homelessness. This effect remained after accounting for age 15 antecedents in peer-group, school, and community environments. Friends' drug use, school suspension, academic failure, and low neighborhood attachment at age 15 mediated the association between less positive family management strategies at age 13 and age 25 homelessness. Despite observing some cross-national differences in levels of family, peer-group, school, and community antecedents, we found that these factors equally increased risk for age 25 homelessness in both states, suggesting similar cross-national influences for young adult homelessness. The findings indicate cross-nationally common adolescent antecedents for young adult homelessness that could be targeted by prevention strategies across international settings.

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

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

A population-based study of homelessness, antisocial behaviour and violence victimisation among young adults in Victoria, Australia.

Homeless young adults are at increased risk for contact with the police and are overrepresented in the justice system. This study explored associations between homelessness, antisocial behaviour and violence victimisation using longitudinal panel data gathered through young adulthood. Data were drawn from a state representative population-based sample of young adults from Victoria, Australia participating in the International Youth Development Study (IYDS; n = 2884, 54% female). Participants were surveyed at age 21 years, with follow-up at ages 23 and 25 years. We examined changes in the prevalence of homelessness and tested hypothesised directional relationships between young adult homelessness, antisocial behaviour and violence victimisation using longitudinal cross-lagged panel models. Multiple-group modelling was used to test whether these relationships were moderated by gender. The prevalence of young adult homelessness was highest at age 21 (6.5%), declining at ages 23 (3.9%) and 25 years (2.5%). Results showed that young adult homelessness, antisocial behaviour and victimisation were related cross-sectionally, but not longitudinally. Gender did not significantly moderate these associations. Findings suggest that the state of homelessness is associated with temporary vulnerability to potentially harmful and problematic situations involving antisocial behaviour and victimisation. These situations are likely to heighten risk for contact with the police and direct physical and psychological harm.

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

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

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.

Longitudinal Associations Between Early-Mid Adolescent Risk and Protective Factors and Young Adult Homelessness in Australia and the United States.

Homelessness is associated with a range of negative health and behavioral outcomes, yet life-course pathways to homelessness from adolescence to early adulthood are not well-documented. This study asks to what extent do early-mid adolescent risk and protective factors predict young adult homelessness, and whether the predictive nature of these factors is similar in Victoria, Australia, and Washington State in the USA. As part of the International Youth Development Study, adolescents were recruited as state representative secondary school samples at grade 7 (age 13, 2002) and longitudinally compared at average age 25. Higher rates of past year homelessness were reported by Washington State (5.24%), compared to Victorian young adults (3.25%). Although some cross-state differences in levels of adolescent demographic, individual, family, peer group, school, and community predictors were found, cross-state comparisons showed these factors were equally predictive of young adult homelessness in both states. In univariate analyses, most adolescent risk and protective factors were significant predictors. Unique multivariate adolescent predictors associated with young adult homelessness included school suspension (adjusted odds ratio [AOR] = 2.76) and academic failure (AOR = 1.94). No significant unique protective effects were found. Prevention and intervention efforts that support adolescents' academic engagement may help in addressing young adult homelessness. The similar cross-state profile of adolescent predictors suggests that programs seeking to support academic engagement may influence risk for homelessness into young adulthood in both states. The similarity in life-course pathways to homelessness suggests that the USA and Australia can profitably translate prevention and intervention efforts to reduce homelessness while continuing to identify modifiable predictors.

Prevalence of homelessness and co-occurring problems: A comparison of young adults in Victoria, Australia and Washington State, United States.

Homelessness is associated with various co-occurring health and social problems yet; few contemporary international studies have examined these problems in young adulthood. This descriptive study presents cross-state comparison of the prevalence of young adult homelessness in Washington State, USA and Victoria, Australia using state representative samples from the International Youth Development Study (IYDS; n = 1,945, 53% female). Associations between young adult homelessness and a range of co-occurring problems were examined using a modified version of the Communities That Care youth survey. Results showed significantly higher rates of past year homelessness were reported by young adults in Washington State (5.24% vs. 3.25% in Victoria). Cross-state differences were evident in levels of friends' drug use, antisocial behavior, weekly income and support from peers. Unemployment (Adjusted Odds Ratio [AOR] = 2.67), antisocial behavior (AOR = 3.54) and victimization (AOR = 3.37) were more likely among young adults reporting homelessness in both states. Young adults with higher weekly income were less likely to report homelessness (AOR = .69) in both states. No significant association between mental health problem symptoms, substance use, family conflict or interaction with antisocial peers and homelessness were found in either state. Rates of violent behavior were more strongly related to young adult homelessness in Washington State than Victoria. The current findings suggest that programs that enable young adults to pursue income and employment, reduce antisocial behavior and include services for those who have been victimized, may help to mitigate harm among young adults experiencing homelessness.
