J Adolesc Health 2023; 73:61-69. [PMID: 36914447 PMCID: PMC10293113 DOI: 10.1016/j.jadohealth.2023.01.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 10/31/2022] [Accepted: 01/21/2023] [Indexed: 03/16/2023]
Abstract
PURPOSE This study builds upon and extends previous longitudinal research on deliberate self-harm (DSH) among youth by investigating which risk and protective factors during adolescence predict DSH thoughts and behavior in young adulthood. METHODS Self-report data came from 1,945 participants recruited as state-representative cohorts from Washington State and Victoria, Australia. Participants completed surveys in seventh grade (average age 13 years), as they transitioned through eighth and ninth grades and online at age 25 years. Retention of the original sample at age 25 years was 88%. A range of risk and protective factors in adolescence for DSH thoughts and behavior in young adulthood were examined using multivariable analyses. RESULTS Across the sample, 9.55% (n = 162) and 2.83% (n = 48) of young adult participants reported DSH thoughts and behaviors, respectively. In the combined risk-protective factor multivariable model for young adulthood DSH thoughts, depressive symptoms in adolescence (adjusted odds ratio [AOR] = 1.05; confidence interval [CI] = 1.00-1.09) increased risk, while higher levels of adolescent adaptive coping strategies (AOR = 0.46; CI = 0.28-0.74), higher levels of adolescent community rewards for prosocial behavior (AOR = 0.73; CI = 0.57-0.93), and living in Washington State decreased risk. In the final multivariable model for DSH behavior in young adulthood, less positive family management strategies during adolescence remained the only significant predictor (AOR = 1.90; CI = 1.01-3.60). DISCUSSION DSH prevention and intervention programs should not only focus on managing depression and building/enhancing family connections and support but also promote resilience through efforts to promote adaptive coping and connections to adults within one's community who recognize and reward prosocial behavior.

Abstract
People who experience social marginalization and vulnerability have uniquely complex health needs and are at risk of poor health outcomes. Regression analyses using longitudinal data from a cross-national, population-based sample of young adults participating in the International Youth Development Study, tested associations between social marginalization and vulnerabilities and physical health, mental health, and substance use outcomes. Participants from Victoria, Australia, and Washington State in the US were surveyed at ages 25 (2014) and 29 years (2018; N = 1944; 46.7% male). A history of adverse childhood experiences (ACEs), LGBT identity, financial insecurity, and justice system involvement at age 25 predicted poor health outcomes at age 28, including lower perceived health status, risk for chronic illness, depression and anxiety symptoms, and diagnosed mental health/substance use disorders. Tests of model equivalence across states showed that a history of ACEs was more strongly related to health status and serious injury at age 28 and justice system involvement at age 25 was more strongly related to age 28 serious injury in Victoria than in Washington State. Findings strengthen the case for future population-based research identifying life-course interventions and state policies for reducing poor health and improving health equity among members of socially marginalized groups.

Young Adult Development Indicators for Indigenous and Non-Indigenous People: A Cross-National Longitudinal Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:17084. [PMID: 36554965 PMCID: PMC9779129 DOI: 10.3390/ijerph192417084] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 12/14/2022] [Accepted: 12/15/2022] [Indexed: 06/17/2023]
Abstract
Worldwide, Indigenous youth face ongoing challenges and inequalities. Increasing our understanding of life course patterns in Indigenous youth will assist the design of strategies and interventions that encourage positive development. This study aimed to increase understanding of resilience and positive development in Indigenous and non-Indigenous youth across Australia and the United States of America. The Australian sample comprised 9680 non-Indigenous and 176 Pacific Islander and Aboriginal and Torres Strait Islander peoples. The USA sample comprised 2258 non-Indigenous and 220 Pacific Islander, Native Hawaiian and Native American/American Indian peoples. Data were used to examine how Indigenous background, volunteering, and community involvement at average age 15 years (Grade 9) predicted five young adult positive development indicators: Year 12 (Grade 12) school completion, tertiary education participation, independent income, paid employment, and intimate relationship formation from age 18 to 28 years. Multilevel regression analyses revealed that while Indigenous youth showed slower increases in positive young adult development over time, when adjusting for socioeconomic disadvantage, there was a reduction in this difference. Moreover, we found that Grade 9 community involvement and volunteering were positively associated with young adult development for Indigenous and non-Indigenous youth. Findings indicate the importance of addressing structural inequalities and increasing adolescent opportunities as feasible strategies to improve positive outcomes for young Indigenous adults.

Heerde JA, Bailey JA, Patton GC, Toumbourou JW. A population-based study of homelessness, antisocial behaviour and violence victimisation among young adults in Victoria, Australia. THE AUSTRALIAN JOURNAL OF SOCIAL ISSUES 2022; 57:762-782. [PMID: 36530738 PMCID: PMC9748854 DOI: 10.1002/ajs4.212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 03/18/2022] [Accepted: 03/19/2022] [Indexed: 06/17/2023]
Abstract
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.

J Adolesc 2021; 91:15-24. [PMID: 34271292 PMCID: PMC8423126 DOI: 10.1016/j.adolescence.2021.06.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 06/20/2021] [Accepted: 06/24/2021] [Indexed: 11/16/2022]
Abstract
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.
