Mediating pathways from childhood ADHD to adolescent tobacco and marijuana problems: roles of peer impairment, internalizing, adolescent ADHD symptoms, and gender / Irene J. ELKINS in Journal of Child Psychology and Psychiatry, 59-10 (October 2018)

IACONO, Auteur Article en page(s) : p.1083-1093 Langues : Anglais (eng) Mots-clés : Adhd gender difference longitudinal studies substance use twins Index. décimale : PER Périodiques Résumé : BACKGROUND: We examined whether increased risk for adolescent tobacco and marijuana problems associated with childhood ADHD is explained by key intermediary influences during adolescence and differs by gender. METHODS: Longitudinal structural equation models examined mediating effects on problems with both substances (or each substance separately) through age-14 peer impairment, internalizing, and adolescent ADHD symptoms in two twin samples, prospectively assessed since age 11 (N = 2,164). Whether these mediators contributed beyond mediating effects of early-adolescent substance use was also considered. Twin difference analyses further illuminated which mediators might be potentially causal. RESULTS: Direct effects of childhood ADHD on age-17 tobacco and marijuana problems (i.e., independent of included mediators) as well as effects of adolescent ADHD symptoms were significant only for females. By contrast, mediation by peer impairment, evident particularly for marijuana, was relatively stronger for males than females. Depression and anxiety were not prospectively associated with age-17 substance problems when earlier substance problems were considered. Consistent with causal influence of early substance use on later problems, monozygotic twins with more severe tobacco or marijuana problems at age 14 than their co-twins were also more likely to have substance problems later in adolescence. CONCLUSIONS: Mediation through peer impairment, continued presence of ADHD symptoms, and early substance use may alter development so that childhood ADHD indirectly contributes to problems with tobacco and marijuana. Targeting gender-sensitive interventions prior to mid-adolescence, before these patterns become established, is essential.

The role of parental marital discord in the etiology of externalizing problems during childhood and adolescence / Amber M. JARNECKE in Development and Psychopathology, 29-4 (October 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-4 (October 2017) . - p.1177-1188 Titre : The role of parental marital discord in the etiology of externalizing problems during childhood and adolescence Type de document : texte imprimé Auteurs : Amber M. JARNECKE, Auteur ; Susan C. SOUTH, Auteur ; Irene J. ELKINS, Auteur ; Robert F. KRUEGER, Auteur ; Erin C. TULLY, Auteur ; William G. IACONO, Auteur Article en page(s) : p.1177-1188 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Previous research has established that parental marital discord is associated with higher levels of offspring externalizing behaviors, but it is unclear how parental relationship functioning is associated with the genetic and environmental variance on a factor of externalizing problems. Thus, the current study assessed how parental marital discord moderates genetic and environmental variance on offspring externalizing problems at two different ages: childhood and late adolescence. That is, the magnitude of genetic and environmental influences on offspring externalizing at ages 11 and 17 was examined as a function of parental marital discord. Consistent with a diathesis–stress model of psychopathology, it was hypothesized that with increasing marital discord, genetic influences on externalizing would be more pronounced. Rather, results indicated that for the 11-year-old sample, nonshared environmental influences were greater when parental marital discord was low, and comparatively, shared environmental influences contributed more to the variance in externalizing problems when parental marital discord was high. No moderation was found for the 17-year-old cohort. In contrast to studies that do not find an effect of the shared environment, these results provide evidence that the common rearing environment has an impact on externalizing problems in preadolescent children.
