SILK, Auteur Article en page(s) : p.1422-1431 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Attention deficit hyperactivity disorder (ADHD) and irritability commonly co-occur, and follow similar developmental trajectories from childhood to adolescence. Understanding of the developmental relationship between these co-occurrences is limited. This study provides a longitudinal assessment of how ADHD diagnostic status and symptom patterns predict change in irritability. Methods A community sample of 337 participants (45.2% ADHD), recruited for the Childhood Attention Project, completed the Affective Reactivity Index (ARI) to measure irritability at baseline (mean age 10.5?years) and follow-up after 18-months. Latent change score models were used to assess how (a) baseline ADHD vs. control group status, (b) baseline symptom domain (inattention, hyperactivity-impulsivity) and (c) longitudinal change in ADHD symptom severity predicted change in irritability. Results Irritability was significantly higher among the ADHD group than controls; however, change in irritability over time did not differ between groups. When assessed across the entire cohort, change in irritability was predicted by higher symptom count in the hyperactive-impulsive domain, but not the inattentive domain. Greater declines in ADHD symptoms over time significantly predicted greater declines in irritability. Baseline ADHD symptom severity was found to significantly predict change in irritability; however, baseline irritability did not significantly predict change in ADHD symptoms. Conclusions ADHD symptoms-particularly hyperactive-impulsive symptoms-predict the degree and trajectory of irritability during childhood and adolescence, even when symptoms are below diagnostic thresholds. The use of longitudinal, dimensional and symptom domain-specific measures provides additional insight into this relationship.

Effects on Later Adjustment of Living in a Stepfamily During Childhood and Adolescence / Jan M. NICHOLSON in Journal of Child Psychology and Psychiatry, 40-3 (March 1999)

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 40-3 (March 1999) . - p.405-416 Titre : Effects on Later Adjustment of Living in a Stepfamily During Childhood and Adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Jan M. NICHOLSON, Auteur ; David M. FERGUSSON, Auteur ; John L. HORWOOD, Auteur Année de publication : 1999 Article en page(s) : p.405-416 Langues : Anglais (eng) Mots-clés : Criminality  drug abuse  family factors  stepfamily  life opportunities  mental health Index. décimale : PER Périodiques Résumé : This paper examines the effects of living in a stepfamily during childhood and adolescence on a range of psychosocial outcomes at age 18 years. Data collected during an 18-year longitudinal study were used to examine a sample of 907 children with respect to: exposure to living in a stepfamily during the period from age 6 to 16 years; measures of psychosocial outcomes including mental health, antisocial behaviour, substance use, restricted life opportunities, and sexual risk-taking at age 18 years; and measures of prospectively collected confounding factors. The analyses revealed that children exposed to living in a stepfamily for the first time between ages 6–16 years had elevated risks of a range of psychosocial outcomes at 18 years. These included elevated risks of: (1) juvenile offending; (2) nicotine dependence; (3) abuse or dependence on illicit substances; (4) leaving school without qualifications; (5) early onset of sexual activity ; and (6) multiple sexual partners. However, these risks were reduced substantially when psychosocial outcomes were adjusted for the confounding effects of antecedent factors such as: family socioeconomic characteristics ; family history of instability, adversity, and conflict; mother's age, religiosity, and smoking; child gender; and preexisting child conduct and attentional problems. After adjustment, the odds ratios between exposure to a stepfamily and adolescent outcomes were nonsignificant. Additional analysis revealed that there were no significant differences in outcomes for boys and girls exposed to stepfamilies. It was concluded that although young people exposed to living in a stepfamily had increased risks of poor psychosocial outcomes, much of this association appeared to be spurious, and arose from confounding social, contextual, and individual factors that were present prior to the formation of the stepfamily.
