Polygenic risks for joint developmental trajectories of internalizing and externalizing problems: findings from the ALSPAC cohort / Lydia Gabriela SPEYER in Journal of Child Psychology and Psychiatry, 63-8 (August 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-8 (August 2022) . - p.948-956 Titre : Polygenic risks for joint developmental trajectories of internalizing and externalizing problems: findings from the ALSPAC cohort Type de document : Texte imprimé et/ou numérique Auteurs : Lydia Gabriela SPEYER, Auteur ; Samuel NEAVES, Auteur ; Hildigunnur Anna HALL, Auteur ; Gibran HEMANI, Auteur ; Michael Vincent LOMBARDO, Auteur ; Aja Louise MURRAY, Auteur ; Bonnie AUYEUNG, Auteur ; Michelle LUCIANO, Auteur Article en page(s) : p.948-956 Langues : Anglais (eng) Mots-clés : Adolescent  Child  Child, Preschool  Female  Humans  Longitudinal Studies  Male  Mothers  Multifactorial Inheritance  Pregnancy  Risk Factors  Smoking  Alspac  Joint mental health trajectories  externalizing  internalizing  polygenic risk Index. décimale : PER Périodiques Résumé : BACKGROUND: Joint developmental trajectories of internalizing and externalizing problems show considerable heterogeneity; however, this can be parsed into a small number of meaningful subgroups. Doing so offered insights into risk factors that lead to different patterns of internalizing/externalizing trajectories. However, despite both domains of problems showing strong heritability, no study has yet considered genetic risks as predictors of joint internalizing/externalizing problem trajectories. METHODS: Using parallel process latent class growth analysis, we estimated joint developmental trajectories of internalizing and externalizing difficulties assessed across ages 4 to 16 using the Strengths and Difficulties Questionnaire. Multinomial logistic regression was used to evaluate a range of demographic, perinatal, maternal mental health, and child and maternal polygenic predictors of group membership. Participants included 11,049 children taking part in the Avon Longitudinal Study of Parents and Children. Polygenic data were available for 7,127 children and 6,836 mothers. RESULTS: A 5-class model was judged optimal: Unaffected, Moderate Externalizing Symptoms, High Externalizing Symptoms, Moderate Internalizing and Externalizing Symptoms and High Internalizing and Externalizing Symptoms. Male sex, lower maternal age, maternal mental health problems, maternal smoking during pregnancy, higher child polygenic risk scores for ADHD and lower polygenic scores for IQ distinguished affected classes from the unaffected class. CONCLUSIONS: While affected classes could be relatively well separated from the unaffected class, phenotypic and polygenic predictors were limited in their ability to distinguish between different affected classes. Results thus add to existing evidence that internalizing and externalizing problems have mostly shared risk factors.

A symptom level perspective on reactive and proactive aggressive behaviours and ADHD symptoms in childhood / Lydia Gabriela SPEYER in Journal of Child Psychology and Psychiatry, 63-9 (September 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-9 (September 2022) . - p.1017-1026 Titre : A symptom level perspective on reactive and proactive aggressive behaviours and ADHD symptoms in childhood Type de document : Texte imprimé et/ou numérique Auteurs : Lydia Gabriela SPEYER, Auteur ; Manuel EISNER, Auteur ; Denis RIBEAUD, Auteur ; Michelle LUCIANO, Auteur ; Bonnie AUYEUNG, Auteur ; Aja Louise MURRAY, Auteur Article en page(s) : p.1017-1026 Langues : Anglais (eng) Mots-clés : Aggression  Attention Deficit Disorder with Hyperactivity/diagnosis/epidemiology  Child  Cohort Studies  Cross-Sectional Studies  Humans  Impulsive Behavior  Adhd  longitudinal network modelling  proactive aggression  reactive aggression  z-proso Index. décimale : PER Périodiques Résumé : OBJECTIVE: Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent childhood disorders, affecting around 3.4% of children worldwide. A common and impairing correlate of ADHD is aggressive behaviour. ADHD symptoms and aggression are both heterogeneous and it has been speculated that certain symptoms of ADHD might be more important in aggressive behaviours of different types than others. This study uses a symptom-level analysis to investigate the concurrent and temporal links between ADHD symptoms and aggressive behaviours. METHODS: Using Gaussian Graphical Models and Graphical Vector Autoregression Models, longitudinal and cross-sectional networks of ADHD symptoms and aggressive behaviours, measured using parent-reported Social Behaviour Questionnaires, were estimated. Participants included 1,246 children taking part in the longitudinal Swiss z-proso cohort study at ages 7, 9 and 11. RESULTS: The longitudinal network highlighted that ADHD symptoms and aggressive behaviours share a multitude of reciprocal temporal relations, with inattentive ADHD symptoms preceding both reactive and proactive aggression. Cross-sectional networks suggested that hyperactive/impulsive symptoms were predominantly connected to reactive aggressive behaviours but also to a form of proactive aggression, namely dominating other children. CONCLUSION: Findings provide preliminary evidence which specific symptoms are the most promising targets for reducing aggressive behaviours in children with ADHD. They also highlight the potential importance of targeting feedback loops resulting from aggressive behaviours. Future research is needed to better understand the mechanisms through which ADHD and aggressive behaviours become linked.
