Co-development of attention deficit hyperactivity disorder and autistic trait trajectories from childhood to early adulthood / Amy SHAKESHAFT in Journal of Child Psychology and Psychiatry, 64-11 (November 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-11 (November 2023) . - p.1596-1607 Titre : Co-development of attention deficit hyperactivity disorder and autistic trait trajectories from childhood to early adulthood Type de document : Texte imprimé et/ou numérique Auteurs : Amy SHAKESHAFT, Auteur ; Jon HERON, Auteur ; Rachel BLAKEY, Auteur ; Lucy RIGLIN, Auteur ; George DAVEY SMITH, Auteur ; Evie STERGIAKOULI, Auteur ; Kate TILLING, Auteur ; Anita THAPAR, Auteur Article en page(s) : p.1596-1607 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Attention deficit hyperactivity disorder (ADHD) and autism, defined as traits or disorders, commonly co-occur. Developmental trajectories of ADHD and autistic traits both show heterogeneity in onset and course, but little is known about how symptom trajectories co-develop into adulthood. Methods Using data from a population cohort, the Avon Longitudinal Study of Parents and Children, we examined correlations between ADHD and autistic traits across development, using the Social Communication Disorders Checklist and ADHD subscale of the Strengths and Difficulties Questionnaire. We modelled joint developmental trajectories of parent-reported ADHD and autistic traits between 4 and 25?years, then characterised trajectory classes based on sociodemographic, perinatal, psychopathology, cognition and social functioning variables and tested for associations with neurodevelopmental/psychiatric polygenic scores (PGS). Results Three classes of trajectories were identified; a typically developing majority with low-stable ADHD-autistic traits (87%), a male-predominant subgroup with child/adolescent-declining traits (6%) and a subgroup with late-emerging traits (6%). ADHD-autistic trait correlations were greatest in young adulthood for the two nontypically developing classes. There were higher rates of emotional and conduct problems, low IQ, childhood seizures and poor social functioning in the declining and late-emerging classes compared to the low-stable class. Emotional, conduct and peer problems were more prevalent during childhood in the childhood/adolescent-declining class compared to other classes, but were more prevalent in young adulthood in the late-emerging class. Neurodevelopmental/psychiatric PGS also differed: both nontypically developing classes showed elevated ADHD PGS compared to the low-stable group, and the late-emerging group additionally showed elevated schizophrenia PGS and decreased executive function PGS, whereas the declining group showed elevated broad depression PGS. Conclusions Distinct patterns of ADHD-autism co-development are present across development in the general population, each with different characterising factors and genetic signatures as indexed by PGS.

Developing and validating a prediction model of adolescent major depressive disorder in the offspring of depressed parents / Alice STEPHENS in Journal of Child Psychology and Psychiatry, 64-3 (March 2023)

Early identification of adolescents at elevated risk of developing major depressive disorder (MDD) in this group could improve early access to preventive interventions. Methods Using longitudinal data from 337 adolescents at high familial risk of depression, we developed a risk prediction model for adolescent MDD. The model was externally validated in an independent cohort of 1,384 adolescents at high familial risk. We assessed predictors at baseline and MDD at follow-up (a median of 2-3 years later). We compared the risk prediction model to a simple comparison model based on screening for depressive symptoms. Decision curve analysis was used to identify which model-predicted risk score thresholds were associated with the greatest clinical benefit. Results The MDD risk prediction model discriminated between those adolescents who did and did not develop MDD in the development (C-statistic=.783, IQR (interquartile range)=.779, .778) and the validation samples (C-statistic=.722, IQR=â’.694, .741). Calibration in the validation sample was good to excellent (calibration intercept=.011, C-slope=.851). The MDD risk prediction model was superior to the simple comparison model where discrimination was no better than chance (C-statistic=.544, IQR=.536, .572). Decision curve analysis found that the highest clinical utility was at the lowest risk score thresholds (0.01-0.05). Conclusions The developed risk prediction model successfully discriminated adolescents who developed MDD from those who did not. In practice, this model could be further developed with user involvement into a tool to target individuals for low-intensity, selective preventive intervention.

Emotional dysregulation in childhood and disordered eating and self-harm in adolescence: prospective associations and mediating pathways / Naomi WARNE in Journal of Child Psychology and Psychiatry, 64-5 (May 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-5 (May 2023) . - p.797-806 Titre : Emotional dysregulation in childhood and disordered eating and self-harm in adolescence: prospective associations and mediating pathways Type de document : Texte imprimé et/ou numérique Auteurs : Naomi WARNE, Auteur ; Jon HERON, Auteur ; Becky MARS, Auteur ; Francesca SOLMI, Auteur ; Lucy BIDDLE, Auteur ; David GUNNELL, Auteur ; Gemma HAMMERTON, Auteur ; Paul MORAN, Auteur ; Marcus MUNAFO, Auteur ; Ian PENTON-VOAK, Auteur ; Andy SKINNER, Auteur ; Anne STEWART, Auteur ; Helen BOULD, Auteur Article en page(s) : p.797-806 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Emotional dysregulation may be a risk factor for disordered eating and self-harm in young people, but few prospective studies have assessed these associations long-term, or considered potential mediators. We examined prospective relationships between childhood emotional dysregulation and disordered eating and self-harm in adolescence; and social cognition, emotional recognition, and being bullied as mediators. Methods We analysed Avon Longitudinal Study of Parents and Children data on 3,453 males and 3,481 females. We examined associations between emotional dysregulation at 7?years and any disordered eating and any self-harm at 16?years with probit regression models. We also assessed whether social cognition (7?years), emotional recognition (8?years) and bullying victimisation (11?years) mediated these relationships. Results Emotional dysregulation at age 7?years was associated with disordered eating [fully adjusted probit B (95% CI) = 0.082 (0.029, 0.134)] and self-harm [fully adjusted probit B (95% CI) = 0.093 (0.036, 0.150)] at age 16?years. There was no evidence of sex interactions or difference in effects between self-harm and disordered eating. Mediation models found social cognition was a key pathway to disordered eating (females 51.2%; males 27.0% of total effect) and self-harm (females 15.7%; males 10.8% of total effect). Bullying victimisation was an important pathway to disordered eating (females 17.1%; males 10.0% of total effect), but only to self-harm in females (15.7% of total effect). Indirect effects were stronger for disordered eating than self-harm. Conclusions In males and females, emotional dysregulation in early childhood is associated with disordered eating and self-harm in adolescence and may be a useful target for prevention and treatment. Mediating pathways appeared to differ by sex and outcome, but social cognition was a key mediating pathway for both disordered eating and self-harm.

Externalising pathways to alcohol-related problems in emerging adulthood / Gemma HAMMERTON in Journal of Child Psychology and Psychiatry, 61-6 (June 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-6 (June 2020) . - p.721-731 Titre : Externalising pathways to alcohol-related problems in emerging adulthood Type de document : Texte imprimé et/ou numérique Auteurs : Gemma HAMMERTON, Auteur ; Alexis C.

The escalation of early CPs into criminal behaviour and heavy alcohol consumption prior to emerging adulthood are both likely to be important pathways. METHODS: Data were analysed from 3,038 young people in a UK birth cohort, the Avon Longitudinal Study of Parents and Children. The exposure was developmental trajectories of CPs ('low', 'childhood-limited', 'adolescent-onset' and 'early-onset persistent') between ages 4 and 13 years. The mediator was latent classes representing heavy alcohol consumption and/ or criminal behaviour at age 15 years. For the outcome, a quadratic latent growth curve was estimated to capture nonlinear change in alcohol-related problems between ages 18 and 23 years. RESULTS: Those with 'early-onset persistent' [b(95% CI) = 1.16 (0.17, 2.14)] and 'adolescent-onset' CPs [b(95% CI) = 1.31 (0.17, 2.45)] had higher levels of alcohol-related problems at age 18 years compared to those with 'low' CPs', but there was little evidence of an association with alcohol-related problems after age 19 years. There was evidence for an indirect effect of 'early-onset persistent' CPs [b(95% CI) = 1.12 (0.52, 1.72)] on alcohol-related problems at age 18 years via the latent classes of alcohol and criminal behaviour in adolescence. This was not found for 'adolescent-onset' CPs [b(95% CI) = 0.35 (-0.36, 1.07)]. CONCLUSIONS: Strong associations exist between early CPs, adolescent alcohol consumption and criminal behaviour and alcohol-related problems at age 18 years. Associations between early CPs and alcohol-related problems weakened considerably across emerging adulthood.

Suicidal ideation during adolescence: The roles of aggregate genetic liability for suicide attempts and negative life events in the past year / Séverine LANNOY in Journal of Child Psychology and Psychiatry, 63-10 (October 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-10 (October 2022) . - p.1164-1173 Titre : Suicidal ideation during adolescence: The roles of aggregate genetic liability for suicide attempts and negative life events in the past year Type de document : Texte imprimé et/ou numérique Auteurs : Séverine LANNOY, Auteur ; Becky MARS, Auteur ; Jon HERON, Auteur ; Alexis C.

Previous studies emphasized the difficulty to cope with negative life events during adolescence as a risk factor for STB. Familial and genetic liability has also been documented to explain STB risk. Nevertheless, less is known about aggregate genetic liability and its possible interaction with negative life events. Moreover, information is needed to understand how these factors differently affect STB in boys and girls. METHODS: We evaluated suicidal ideation at 17years old and examined the role of aggregate genetic liability, negative life events, and their interaction in a sample of 2,571 adolescents. Aggregate genetic liability was measured using a polygenic score (PGS) for suicide attempts. Negative life events were assessed in the past year and included parental divorce and hospitalizations, death of friends and relatives, bullying, failure-related events, and involvement with drugs. We conducted univariable and multivariable general linear models stratified by sex and evaluated the interactions between PGS and negative life events in subsequent models. RESULTS: Analyses showed that suicidal ideation in boys is associated with failure to achieve something important (estimate=0.198), bullying (estimate=0.285), drug use (estimate=0.325), and parental death (estimate=0.923). In girls, both aggregate genetic liability (estimate=0.041) and negative life events (failure at school [estimate=0.120], failure to achieve something important [estimate=0.279], drug use [estimate=0.395], and bullying [estimate=0.472]) were associated with suicidal ideation. Interaction analyses suggested that PGS interacted with drug use and failures at school, though this would need additional support. CONCLUSIONS: These findings represent significant contributions to the fundamental understanding of STB in adolescence, suggesting to monitor the impact of negative life events during adolescence to better prevent suicide risk. Genetic liability is also of importance in girls and might influence the way they respond to environmental threats.
