Editorial: The psychopathology p factor: will it revolutionise the science and practice of child and adolescent psychiatry? / A. RONALD in Journal of Child Psychology and Psychiatry, 60-5 (May 2019)
[article]
Titre : Editorial: The psychopathology p factor: will it revolutionise the science and practice of child and adolescent psychiatry? Type de document : Texte imprimé et/ou numérique Auteurs : A. RONALD, Auteur Article en page(s) : p.497-499 Langues : Anglais (eng) Mots-clés : Psychopathology autism child and adolescent psychiatry genetics neurodevelopment p factor Index. décimale : PER Périodiques Résumé : The psychopathology p factor has emerged from a series of strong empirical studies, largely in the adult psychiatry literature. Here, some of the recent findings relating to the p factor in children and adolescents are considered and the implications for child and adolescent psychiatry are discussed. Is it essential to covary for 'p' when we study specific domains of psychopathology? Do neurodevelopmental conditions make up part of the psychopathology p factor? How do we treat the 'p factor' in clinics? This editorial considers some of the contributions from this issue of Journal of Child Psychology and Psychiatry together with the wider literature that speak to these issues.

Titre : An integrative evolutionary framework for psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : Marco DEL GIUDICE, Auteur ; John D. HALTIGAN, Auteur Article en page(s) : p.1-11 Langues : Anglais (eng) Mots-clés : comorbidity evolutionary psychiatry evolutionary psychopathology heterogeneity life history strategies p factor transdiagnostic models Index. décimale : PER Périodiques Résumé : The field of psychopathology is in a transformative phase, and is witnessing a renewed surge of interest in theoretical models of mental disorders. While many interesting proposals are competing for attention in the literature, they tend to focus narrowly on the proximate level of analysis and lack a broader understanding of biological function. In this paper, we present an integrative framework for mental disorders built on concepts from life history theory, and describe a taxonomy of mental disorders based on its principles, the fast-slow-defense model (FSD). The FSD integrates psychopathology with normative individual differences in personality and behavior, and allows researchers to draw principled distinctions between broad clusters of disorders, as well as identify functional subtypes within current diagnostic categories. Simulation work demonstrates that the model can explain the large-scale structure of comorbidity, including the apparent emergence of a general ''p factor'' of psychopathology. A life history approach also provides novel integrative insights into the role of environmental risk/protective factors and the developmental trajectories of various disorders.

Titre : Difficulties with emotion regulation as a transdiagnostic mechanism linking child maltreatment with the emergence of psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : David G. WEISSMAN, Auteur ; Debbie BITRAN, Auteur ; Adam Bryant MILLER, Auteur ; Jonathan D. SCHAEFER, Auteur ; Margaret A. SHERIDAN, Auteur ; Katie A. MCLAUGHLIN, Auteur Article en page(s) : p.899-915 Langues : Anglais (eng) Mots-clés : adversity attention bias p factor rumination threat Index. décimale : PER Périodiques Résumé : Childhood maltreatment is associated with increased risk for most forms of psychopathology. We examine emotion dysregulation as a transdiagnostic mechanism linking maltreatment with general psychopathology. A sample of 262 children and adolescents participated; 162 (61.8%) experienced abuse or exposure to domestic violence. We assessed four emotion regulation processes (cognitive reappraisal, attention bias to threat, expressive suppression, and rumination) and emotional reactivity. Psychopathology symptoms were assessed concurrently and at a 2-year longitudinal follow-up. A general psychopathology factor (p factor), representing co-occurrence of psychopathology symptoms across multiple internalizing and externalizing domains, was estimated using confirmatory factor analysis. Maltreatment was associated with heightened emotional reactivity and greater use of expressive suppression and rumination. The association of maltreatment with attention bias varied across development, with maltreated children exhibiting a bias toward threat and adolescents a bias away from threat. Greater emotional reactivity and engagement in rumination mediated the longitudinal association between maltreatment and increased general psychopathology over time. Emotion dysregulation following childhood maltreatment occurs at multiple stages of the emotion generation process, in some cases varies across development, and serves as a transdiagnostic mechanism linking child maltreatment with general psychopathology.

FOX, Auteur Article en page(s) : p.774-783 Langues : Anglais (eng) Mots-clés : general factor motor activity p factor psychopathology temperament Index. décimale : PER Périodiques Résumé : Recent models of psychopathology suggest the presence of a general factor capturing the shared variance among all symptoms along with specific psychopathology factors (e.g., internalizing and externalizing). However, few studies have examined predictors that may serve as transdiagnostic risk factors for general psychopathology from early development. In the current study we examine, for the first time, whether observed and parent-reported infant temperament dimensions prospectively predict general psychopathology as well as specific psychopathology dimensions (e.g., internalizing and externalizing) across childhood. In a longitudinal cohort (N = 291), temperament dimensions were assessed at 4 months of age. Psychopathology symptoms were assessed at 7, 9, and 12 years of age. A bifactor model was used to estimate general, internalizing, and externalizing psychopathology factors. Across behavioral observations and parent-reports, higher motor activity in infancy significantly predicted greater general psychopathology in mid to late childhood. Moreover, low positive affect was predictive of the internalizing-specific factor. Other temperament dimensions were not related with any of the psychopathology factors after accounting for the general psychopathology factor. The results of this study suggest that infant motor activity may act as an early indicator of transdiagnostic risk. Our findings inform the etiology of general psychopathology and have implications for the early identification for children at risk for psychopathology.

Titre : Longitudinal relations between impaired executive function and symptoms of psychiatric disorders in childhood Type de document : Texte imprimé et/ou numérique Auteurs : Marte HALSE, Auteur ; Silje STEINSBEKK, Auteur ; ASA HAMMAR, Auteur ; Lars WICHSTRØM, Auteur Article en page(s) : p.1574-1582 Langues : Anglais (eng) Mots-clés : Child Adolescent Child, Preschool Humans Executive Function Attention Deficit and Disruptive Behavior Disorders/epidemiology Conduct Disorder Attention Deficit Disorder with Hyperactivity Anxiety Disorders Adolescents Brief Capa Papa child development developmental psychopathology longitudinal mental health p factor psychiatric disorder self-regulation Index. décimale : PER Périodiques Résumé : BACKGROUND: Malfunctioning of executive functions correlates with psychopathology in children. However, the directionality, the extent to which the relation varies for various disorders, and whether prospective relations afford causal interpretations are not known. METHODS: A community sample of Norwegian children (n=874) was studied biennially from the age of 6 to 14 years. Executive functions were assessed using the Behavior Rating Inventory of Executive Function Teacher-report and symptoms of psychopathology were assessed using the Preschool Age Psychiatric Assessment (age 6; parents) and Child and Adolescent Psychiatric Assessment (ages 8-14; children and parents). Prospective reciprocal relations were examined using a random intercept cross-lagged panel model that adjusts for all unobserved time-invariant confounders. RESULTS: Even when time-invariant confounders were accounted for, reduced executive functions predicted increased symptoms of depressive disorders, anxiety disorders, attention-deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) 2 years later, even when previous changes in these symptoms were adjusted for. The level of prediction (B=.83, 95% CI [.37, 1.3]) was not different for different disorders or ages. Conversely, reduced executive functions were predicted by increased symptoms of all disorders (B=.01, 95% CI [.01, .02]). CONCLUSIONS: Reduced executive functioning may be involved in the etiology of depression, anxiety, ADHD, and ODD/CD to an equal extent. Moreover, increased depression, anxiety, ADHD, and ODD/CD may negatively impact executive functioning.
