Experimentation versus progression in adolescent drug use: A test of an emerging neurobehavioral imbalance model / Atika KHURANA in Development and Psychopathology, 27-3 (August 2015)

GIANNETTA, Auteur ; Hallam HURT, Auteur Article en page(s) : p.901-913 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Based on an emerging neuroscience model of addiction, this study examines how an imbalance between two neurobehavioral systems (reward motivation and executive control) can distinguish between early adolescent progressive drug use and mere experimentation with drugs. Data from four annual assessments of a community cohort (N = 382) of 11- to 13-year-olds were analyzed to model heterogeneity in patterns of early drug use. Baseline assessments of working memory (an indicator of the functional integrity of the executive control system) and three dimensions of impulsivity (characterizing the balance between reward seeking and executive control systems) were used to predict heterogeneous latent classes of drug use trajectories from early to midadolescence. Findings revealed that an imbalance resulting from weak executive control and heightened reward seeking was predictive of early progression in drug use, while heightened reward seeking balanced by a strong control system was predictive of occasional experimentation only. Implications of these results are discussed in terms of preventive interventions that can target underlying weaknesses in executive control during younger years, and potentially enable at-risk adolescents to exercise greater self-restraint in the context of rewarding drug-related cues.

Intergenerational transmission of maltreatment: A multilevel examination / Leslie D. LEVE in Development and Psychopathology, 27-4 (Part 2) (November 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-4 (Part 2) (November 2015) . - p.1429-1442 Titre : Intergenerational transmission of maltreatment: A multilevel examination Type de document : Texte imprimé et/ou numérique Auteurs : Leslie D. LEVE, Auteur ; Atika KHURANA, Auteur ; Emily B. REICH, Auteur Article en page(s) : p.1429-1442 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Despite the commonly held belief that there is a high degree of intergenerational continuity in maltreatment, studies to date suggest a mixed pattern of findings. One reason for the variance in findings may be related to the measurement approach used, which includes a range of self-report and official indicators of maltreatment and both cross-sectional and longitudinal designs. This study attempted to shed light on the phenomenon of intergenerational continuity of maltreatment by examining multiple indicators of perpetration of maltreatment in young adults and multiple risk factors across different levels within an individual's social ecology. The sample included 166 women who had been placed in out-of-home care as adolescents (>85% had a substantiated maltreatment incident) and followed into young adulthood, and included three waves of adolescent data and six waves of young adult data collected across 10 years. The participants were originally recruited during adolescence as part of a randomized controlled trial examining the efficacy of the Treatment Foster Care Oregon intervention. Analyses revealed weak to modest associations among the three indicators of perpetration of maltreatment in young adulthood, that is, official child welfare records, self-reported child welfare system involvement, and self-reported maltreatment (r = .03–.51). Further, different patterns of prediction emerged as a function of the measurement approach. Adolescent delinquency was a significant predictor of subsequent self-reported child welfare contact, and young adult partner risk was a significant predictor of perpetration of maltreatment as indexed by both official child welfare records and self-reported child welfare contact. In addition, women who were originally assigned to the intervention condition reported perpetrating less maltreatment during young adulthood. Implications for measurement and interventions related to reducing the risk for intergenerational transmission of risk are discussed.

Using an adoption–biological family design to examine associations between maternal trauma, maternal depressive symptoms, and child internalizing and externalizing behaviors / Aleksandria Perez GRABOW in Development and Psychopathology, 29-5 (December 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-5 (December 2017) . - p.1707-1720 Titre : Using an adoption–biological family design to examine associations between maternal trauma, maternal depressive symptoms, and child internalizing and externalizing behaviors Type de document : Texte imprimé et/ou numérique Auteurs : Aleksandria Perez GRABOW, Auteur ; Atika KHURANA, Auteur ; Misaki N.

LEVE, Auteur Article en page(s) : p.1707-1720 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Maternal trauma is a complex risk factor that has been linked to adverse child outcomes, yet the mechanisms underlying this association are not well understood. This study, which included adoptive and biological families, examined the heritable and environmental mechanisms by which maternal trauma and associated depressive symptoms are linked to child internalizing and externalizing behaviors. Path analyses were used to analyze data from 541 adoptive mother–adopted child (AM–AC) dyads and 126 biological mother–biological child (BM–BC) dyads; the two family types were linked through the same biological mother. Rearing mother's trauma was associated with child internalizing and externalizing behaviors in AM–AC and BM–BC dyads, and this association was mediated by rearing mothers’ depressive symptoms, with the exception of biological child externalizing behavior, for which biological mother trauma had a direct influence only. Significant associations between maternal trauma and child behavior in dyads that share only environment (i.e., AM–AC dyads) suggest an environmental mechanism of influence for maternal trauma. Significant associations were also observed between maternal depressive symptoms and child internalizing and externalizing behavior in dyads that were only genetically related, with no shared environment (i.e., BM–AC dyads), suggesting a heritable pathway of influence via maternal depressive symptoms.
