(140) Mapping Psychosocial Pathways From Trauma to Substance Use Risk in Immigrant Adolescents

Background & Introduction: As of 2025, the foreign-born population in the United States has reached approximately 53.3 million, underscoring the growing relevance of immigrant health across the region. Adolescence is a critical developmental period characterized by rapid neurobiological, psychological, and social change. Prior research has demonstrated robust associations between trauma exposure during migration and adverse mental health outcomes among youth. However, the literature remains limited in its integration of immigration-related stressors, such as acculturation demands, language barriers, discrimination, and identity negotiation, and its interaction with developmental vulnerability to influence substance use risk during adolescence. Refugee and immigrant adolescents may be particularly susceptible due to incomplete biopsychosocial and cognitive development, reliance on caregivers, and limited coping resources. This narrative review seeks to synthesize existing evidence to identify key psychosocial pathways linking trauma and culturally specific stressors to substance use risk among immigrant adolescents, while also highlighting the protective factors and intervention-relevant targets to inform prevention and early intervention efforts.

Methods: A structured narrative review was conducted using PubMed, PsycINFO, and Google Scholar. Searches combined predefined terms related to immigrant and refugee adolescents, trauma exposure, psychosocial stressors (including loneliness and acculturation), and substance use outcomes. Peer-reviewed studies published between 2010 and 2025 were systematically screened, yielding sixteen eligible articles. The studies consisted of quantitative, qualitative, and review articles. Study characteristics and key outcomes were extracted and organized into thematic domains. Convergent findings across studies were analyzed to identify recurring psychosocial pathways, thereby reinforcing thematic synthesis. This data was consequently used to develop a conceptual psychosocial framework linking trauma exposure to substance use risk through culturally specific stress processes and social isolation, with family and cultural factors modeled as moderators.

Results: Across the reviewed literature, thematic synthesis identified interrelated psychosocial pathways linking immigration-related experiences to substance use risk among immigrant and refugee adolescents. Trauma and adverse experiences associated with migration, displacement, and family separation consistently established a baseline vulnerability characterized by elevated psychological distress. Substance use risk appeared to arise less from trauma exposure alone than from downstream stress and coping processes, mainly emotion-focused and avoidant, that unfolded over adolescence.

Culturally specific stressors, including discrimination, acculturation demands, and generational status, further compounded vulnerability. First and second-generation youth demonstrated persistently elevated psychosocial distress compared to later-generation peers, suggesting sustained developmental risk shaped by ongoing cultural and contextual stressors rather than transient adjustment difficulties.
Social isolation and loneliness emerged as proximal mechanisms linking trauma and cultural stress to substance use vulnerability. Perceived marginalization and lower subjective social status within school and community settings heightened risk, while shifts in peer context influenced exposure to substance use norms. Greater integration into mainstream peer networks was associated with increased exposure to permissive substance use attitudes, suggesting attenuation of certain immigrant-related protective effects.

Across studies, family cohesion, parental support, and culturally responsive family-based processes consistently functioned as protective factors. Evidence from family-based and culturally adapted intervention studies such as Family Unidas, preparing the new generation, CAPAS: Criando con Amor, Promoviendo Armonía y Superación, a family skills program, demonstrated that strengthening parent–adolescent communication, parental monitoring, and presence of role models within the community was associated with reduced substance use risk and delayed initiation among immigrant adolescents. These protective effects were most pronounced in the context of high trauma exposure and acculturative stress, reinforcing the role of family systems as moderators within the psychosocial stress process.

Together, these findings support a psychosocial pathway in which trauma, cultural stressors, social integration, and family/cultural resources interact to shape substance use risk among immigrant adolescents.

Conclusion & Discussion: This review highlights trauma and culturally specific stressors as key drivers of substance use risk among immigrant adolescents, operating through psychosocial pathways involving psychological distress, social isolation, acculturation challenges, and peer influence. Evidence-based interventions such as Familias Unidas, Preparing the New Generation (FPNG), family skills program, and CAPAS demonstrate that strengthening family cohesion and culturally responsive processes can mitigate risk by enhancing parental monitoring, communication, support likely due to improved bicultural identity integration.
Effective programs combine surface-level adaptations (e.g., language, culturally relevant materials) with deep cultural structures (e.g., parenting norms, intergenerational values, parent–child group engagement), increasing relevance and engagement while addressing social isolation and maladaptive coping. Such models can guide early interventions in schools, healthcare, and community settings, providing practical pathways to reduce substance use disparities.
Policy implications include prioritizing multilevel strategies that integrate structural supports with family- and community-based programs to promote healthy development, smoother integration of bicultural identity, and consequently reduce disparities.
Limitations include heterogeneous study designs and outcomes, reliance on self-report increasing risk of recall bias, underrepresentation of some immigrant subgroups such as African Americans, and a psychosocial pathway derived from thematic synthesis that requires longitudinal and quantitative validation.
