Brains of a feather flocking together? Peer and individual neurobehavioral risks for substance use across adolescence / J. KIM-SPOON in Development and Psychopathology, 31-5 (December 2019)

However, little is known about the role of brain functions in pathways connecting peer contexts and health risk behaviors. We tested developmental cascade models to evaluate contributions of adolescent risk taking, peer influences, and neurobehavioral variables of risk processing and cognitive control to substance use among 167 adolescents who were assessed annually for four years. Risk taking at Time 1 was related to substance use at Time 4 indirectly through peer substance use at Time 2 and insular activation during risk processing at Time 3. Furthermore, neural cognitive control moderated these effects. Greater insular activation during risk processing was related to higher substance use for those with greater medial prefrontal cortex activation during cognitive control, but it was related to lower substance use among those with lower medial prefrontal cortex activation during cognitive control. Neural processes related to risk processing and cognitive control play a crucial role in the processes linking risk taking, peer substance use, and adolescents' own substance use.

Longitudinal pathways linking family risk, neural risk processing, delay discounting, and adolescent substance use / J. KIM-SPOON in Journal of Child Psychology and Psychiatry, 60-6 (June 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-6 (June 2019) . - p.655-664 Titre : Longitudinal pathways linking family risk, neural risk processing, delay discounting, and adolescent substance use Type de document : Texte imprimé et/ou numérique Auteurs : J. KIM-SPOON, Auteur ; N. LAUHARATANAHIRUN, Auteur ; K. PEVIANI, Auteur ; Alexis BRIEANT, Auteur ; K. DEATER-DECKARD, Auteur ; Warren K. BICKEL, Auteur ; B. KING-CASAS, Auteur Article en page(s) : p.655-664 Langues : Anglais (eng) Mots-clés : Family multi-risk index  delay discounting  functional neuroimaging  risk processing  substance use Index. décimale : PER Périodiques Résumé : BACKGROUND: Current theories in neuroscience emphasize the crucial role of individual differences in the brain contributing to the development of risk taking during adolescence. Yet, little is known about developmental pathways through which family risk factors are related to neural processing of risk during decision making, ultimately contributing to health risk behaviors. Using a longitudinal design, we tested whether neural risk processing, as affected by family multi-risk index, predicted delay discounting and substance use. METHOD: One hundred and fifty-seven adolescents (aged 13-14 years at Time 1, 52% male) were assessed annually three times. Family multi-risk index was measured by socioeconomic adversity, household chaos, and family risk-taking behaviors. Delay discounting was assessed by a computerized task, substance use by questionnaire data, and risk-related neural processing by blood-oxygen-level-dependent (BOLD) responses in the amygdala during a lottery choice task. RESULTS: Family multi-risk index at Time 1 was related to adolescent substance use at Time 3 (after controlling for baseline substance use) indirectly through heightened amygdala sensitivity to risks and greater delay discounting. CONCLUSIONS: Our results elucidate the crucial role of neural risk processing in the processes linking family multi-risk index and the development of substance use. Furthermore, risk-related amygdala activation and delay discounting are important targets in the prevention and treatment of substance use among adolescents growing up in high-risk family environments.
