| Abstract | Introduction: Adolescent substance use remains a major cause of concern in the U.S. and Hispanic/Latino adolescents are at particular risk for substance use at an early age. California data show that Hispanic/Latino youth initiate substance use earlier (in 8th grade) at higher rates than youth who identify as white. This dissertation research integrated theories of emerging adulthood, acculturation, stress and coping to investigate the etiology of substance use among Hispanic/Latino adolescents in Southern California. Specifically, three studies were conducted to investigate the relationships among three sociocultural stress factors (acculturative stress, parent-adolescent acculturation discrepancy, perceived stress and emerging adulthood transition stress), depressive symptomatology, and coping styles (engagement and disengagement) in the etiology of substance use (cigarette, alcohol and marijuana) among Hispanic/Latino adolescents in Southern California.; Methods: The three studies comprising this dissertation were conducted with self-report survey data originating from two large school-based studies examining drug use among high school students in the Los Angeles metropolitan area. Only data from participants who identified as Hispanic/Latino were used in these dissertation studies. The first study in this dissertation was conducted with baseline data from a randomized, controlled trial testing the effectiveness of an intervention, Project Towards No Drug Abuse (TND) in preventing substance use among continuation high school students (n=1046). The second and third studies in this dissertation were conducted with data from a longitudinal study of cultural determinants of substance use among a sample of primarily Hispanic/Latino regular high school students (n=1546). In all studies, multilevel linear regression analyses were conducted to estimate the associations and longitudinal predictions of the past 30-day use of all three substances (cigarettes, alcohol and marijuana) by the sociocultural stress factors and coping (chapters 2, 3, and 4). The interaction effects of engagement and disengagement coping styles on the relationships between the sociocultural stress variables and substance use were investigated (chapters 2, 3 and 4). In addition, the mediation of the cultural stress, coping and substance use relationships by depressive symptomatology and the potential moderation of the mediated effect by coping styles were examined in study 3 (chapter 4).; Results: The findings from the three studies showed that sociocultural stress factors are associated with and predict past 30-day substance use, especially cigarette smoking. Study 1 (chapter 2) analyses showed that emerging adulthood transition stress was statistically significantly associated with the past 30-day use of all three substances (cigarettes, alcohol and marijuana). Stratified analyses by acculturation level demonstrated that emerging adulthood transition stress was only associated with cigarette smoking among more highly acculturated youth and only associated with alcohol and marijuana use among less acculturated youth (chapter 2). Engagement coping was inversely associated with substance use across studies (chapters 2, 3 and 4), while disengagement coping was positively associated with only alcohol and marijuana use in study 1 (chapter 2) and alcohol use in studies 2 and 3 (chapters 3 and 4). Acculturative stress statistically significantly predicted past-30-day cigarette smoking but not alcohol or marijuana use. Parent-adolescent acculturation discrepancy was only a marginally significant predictor of past 30-day smoking, and not the past-30-day use of alcohol or marijuana (chapter 3).; Across the three studies several interaction effects were found between both coping styles and all three sociocultural stress factors (acculturative stress, parent-adolescent acculturation discrepancy, emerging adulthood transition stress) and perceived stress in the substance use models (chapters 2, 3, and 4). Aside from the statistically significant buffering of engagement coping on the relationship between perceived stress and cigarette smoking (chapter 2), the interaction effects did not support a stress-buffering role of coping (chapters 2, 3, and 4). Acculturative stress (measured at baseline) predicted depressive symptomatology at one-year follow-up. Depressive symptomatology (at one-year follow-up) was positively associated with the past 30-day use of all three substances at two-year follow-up, but was not found to mediate the relationship between acculturative stress and substance use. In study 3 (chapter 4), there was no evidence for the hypothesized mediated moderation effects.; Conclusion: Overall, this research demonstrated that social and cultural influences on adolescent substance use may be important determinants of substance use among Hispanic/Latino adolescents, especially cigarette smoking. However, among these samples of Hispanic/Latino youth, the psychosocial construct of coping interacts with sociocultural stress factors in unique ways that counter findings of previous stress-coping research. Additional research should include coping measures that assess aspects of the coping process such as perceived threat and controllability of the stressor. Findings across the three studies suggest that more research is warranted to investigate the simultaneous contribution of the sociocultural stress factors and coping to substance use across the emerging adulthood transition. |
