Emerging developmental perspectives suggest that adverse rearing environments promote neurocognitive adaptations that heighten impulsivity and increase vulnerability to risky behavior. Although studies document links between harsh rearing environments and impulsive behavior on substance use, the developmental hypothesis that impulsivity acts as mechanism linking adverse rearing environments to downstream substance use remains to be investigated. The present study investigated the role of impulsivity in linking child abuse and neglect with adult substance use using data from (a) a longitudinal sample of youth (Study 1, N = 9,421) and (b) a cross-sectional sample of adults (Study 2, N = 1,011). In Study 1, the links between child abuse and neglect and young adult smoking and marijuana use were mediated by increases in adolescent impulsivity. In Study 2, indirect links between child abuse and neglect and substance use were evidenced via delayed reward discounting and impulsivity traits. Among impulsivity subcomponents, robust indirect effects connecting childhood experiences to cigarette use emerged for negative urgency. Negative urgency, positive urgency, and sensation seeking mediated the effect of child abuse and neglect on cannabis and alcohol use. Results suggest that child abuse and neglect increases risk for substance use in part, due to effects on impulsivity. Individuals with adverse childhood experiences may benefit from substance use preventive intervention programs that target impulsive behaviors.
Neglectful rearing is linked with young adults' substance use and abuse, though the developmental mechanisms that underlie this association are unclear. The present study examines links between self-esteem growth during adolescence, childhood supervisory versus physical neglect severity, and substance use and abuse in young adulthood. A sample of youth was obtained from the Add Health study (N = 8738; 55.4 %-Female; 20 %-African American, 14.7 %-Hispanic). Growth mixture modeling analyses supported declining, ascending, and stable high self-esteem trajectories. The declining and ascending trajectories reported greater neglect and alcohol abuse (but not use) as well as cannabis use and abuse. The findings suggest that compromised development of self-esteem underlies associations between neglect and substance use and abuse. Preventive interventions may benefit from targeting self-esteem among neglected youth.
Past adverse socioeconomic circumstances, including childhood and adulthood adversity, are potential sources of unobserved heterogeneity of multidimensional health trajectories even in late older years. The identification of members of latent trajectory health classes and the associated antecedents linked to health class membership are consistent with a life-course conceptual framework. Thus, multidimensional health capturing the full range of health problems needs to be investigated for proper examination of socioeconomic correlates of health. This facilitates the understanding of the associations between life-course experiences and health in late old age that ultimately have implications for prevention and intervention.
Hispanic immigrant youth engage in increased health risk behaviors, such as alcohol misuse, due in part to being confronted with acculturative stress in addition to facing major normative developmental challenges, such as identity consolidation (Berry et al. in Appl Psychol 55:303-332, 2006). Using a developmental psychopathology framework, in the present study we examined the effect of bicultural stress on alcohol misuse among immigrated Hispanic adolescents, indirectly through trajectories of identity formation and alcohol expectancies. Our sample consisted of 302 recently immigrated Hispanic adolescents (53 % male; Mage = 14.5 at baseline) who were interviewed every 6 months for 3 years. Bivariate growth curve modeling was used to examine the influence of initial early bicultural stress on later alcohol misuse via change in identity development (i.e., coherence and confusion) and subsequent growth in cognitive alcohol expectancies. Findings revealed that initial levels and growth of identity coherence were not significantly associated with either bicultural stress or tension reduction (TR) alcohol expectancies. Multiple mediation analyses indicated that the effect of bicultural stress at time 1 on the frequency of being drunk at time 6 was mediated via high initial levels of identity confusion, followed by growth in risky TR expectancies (T4-T6). A developmental approach to the genesis of alcohol use problems in immigrant youth is discussed.
Adolescent health behaviors, especially health risk behaviors, have previously been linked to distal (i.e., family economic pressure) and proximal (i.e., parental support) contributors. However, few studies have examined both types of contributors along with considering health promoting and health risk behaviors separately. The present study investigated the influences of family economic hardship, supportive parenting as conceptualized by self-determination theory, and individual psychosocial and behavioral characteristics (i.e., mastery and delinquency, respectively) on adolescents' health promoting and health risk behaviors. We used structural equation modeling to analyze longitudinal data from a sample of Caucasian adolescent children and their mothers and fathers (N = 407, 54 % female) to examine direct and indirect effects, as well as gender symmetry and asymmetry. Findings suggest that family economic pressure contributed to adolescent mastery and delinquency through supportive parenting. Further, supportive parenting indirectly affected adolescent health risk behaviors only through delinquency, whereas supportive parenting indirectly influenced health promoting behaviors only through mastery, suggesting different developmental pathways for adolescent health risk and health promoting behaviors. Testing for gender symmetry of the full model showed that maternal and paternal parenting contributed to females' health risk behaviors directly, while maternal and paternal parenting contributed to males' health risk behaviors through delinquency. Gender symmetry was largely unsupported. The study highlights key direct and indirect pathways to adolescent health risk and health promoting behaviors within a family stress model and self-determination theory framework, and also highlights important gender differences in these developmental pathways.
This study examined (a) transition patterns from adolescent-specific depressive symptom trajectory classes to young adult-specific trajectory classes (N = 537; 15-26 years) and (b) identified risk factors associated with these transition patterns. The latent classes and transition analyses identified three transitional patterns of depressive symptom trajectories, including a deteriorating pattern (8.2%), a recovering pattern (22.5%), and a consistently low pattern (69.3%). Additionally, the results showed that contextual risk factors (i.e., negative economic events, negative romantic relationships, and low college enrolment rates) in the transition period to young adulthood were more positively associated with deteriorated or recovered transition patterns of depressive symptom trajectories than with the consistently low transition patterns even after taking into account the effects of adolescent risk factors. The identification of dynamic transition patterns in depressive symptom trajectories from adolescence to young adulthood and risk factors provide useful tools for preventive and intervention efforts. Statement of contribution What is already known on this subject? Heterogeneous trajectories of depressive symptoms across adolescence and young adulthood have been reported. Psychosocial characteristics differentiate trajectories of depressive symptoms from adolescence to young adulthood. What does this study add? Dynamic transition patterns of depressive symptom trajectories are found between adolescence and young adulthood. Life experiences in the transition period are uniquely associated with the transition patterns of depressive symptom trajectories even after adjusting the effects of adolescent characteristics.
Purpose The present study investigated the psycho-physiological inter and intra-individual processes that mediate the linkage between childhood/adolescent socioeconomic adversities and adult health outcomes. Specifically, the proposed model examined the roles of youth depressive symptoms and BMI trajectories as mediators that explain the link between early adversity and young adults’ general health and physical illnesses after controlling for gender, race/ethnicity, and earlier general health reports. Methods Using a nationally representative sample of 12,424 from National Longitudinal Study of Adolescent Health (Add Health), this study used growth curve modeling to consider both the severity (initial level) as well as the change over time (deterioration or elevation) as psycho-physiological mediators, thereby acknowledging multiple facets of depressive symptoms and BMI trajectories as psych-physiological mediators of early adversity to adult health. Results Results provide evidence for (a) the influence of early childhood and early adolescent cumulative socioeconomic adversity on both the initial levels and changes over time of depressive symptoms and BMI and (b) the independent influences depressive symptoms and BMI trajectories on the general health and the physical illnesses of young adults Conclusions These findings contribute valuable knowledge to existing research by elucidating how early adversity exerts an enduring long-term influence on physical health problems in young adulthood; further, this information suggests effective intervention and prevention programs should incorporate multiple facets (severity and change over time) of multiple mechanisms (psychological and physiological).
