Multiple developmental pathways underlying conduct problems: A multitrajectory framework / Jules R. DUGRE in Development and Psychopathology, 34-3 (August 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-3 (August 2022) . - p.1115-1124 Titre : Multiple developmental pathways underlying conduct problems: A multitrajectory framework Type de document : texte imprimé Auteurs : Jules R. DUGRE, Auteur ; Stéphane POTVIN, Auteur Article en page(s) : p.1115-1124 Langues : Anglais (eng) Mots-clés : callousness  conduct disorder  developmental trajectories  hyperactivity  irritability Index. décimale : PER Périodiques Résumé : In the past decades, there has been an overemphasis of a descriptive/behavioral approach to study conduct disorder. In an equifinal perspective, we aimed to examine the developmental multitrajectory groups of psychological features (irritability, interpersonal callousness, hyperactivity/impulsivity, and depressive “anxiety symptoms) and their associations with conduct problems. In a population-based cohort (n = 1,309 participants followed from 5 months to 17 years old), latent-class growth analysis was performed for each psychological feature to identify a two-trajectory model (from ages 6 to 12 years). Based on parameter estimates of the two-trajectory models for each of the four psychological features, a parallel process growth mixture model identified eight significant developmental patterns that were subsequently compared with typically developing children. Furthermore, we observed that while interpersonal callousness conferred an increased risk for childhood and adolescence conduct problems, its co-occurrence with hyperactivity/impulsivity, irritability, and/or depressive “anxiety symptoms heightened the general risk, but also predicted distinct subtypes of conduct problems (i.e., aggressive and rule-breaking behaviors). Thus, by studying complex developmental combinations of psychological features, we observed qualitatively distinct pathways towards conduct problems. A multitrajectory framework of psychological features should be considered as a significant step towards unveiling the multiple etiological pathways leading to conduct disorder and its substantial clinical heterogeneity.

Resting-state alterations in emotion salience and default-mode network connectivity in atypical trajectories of psychotic-like experiences / Roxane ASSAF in Development and Psychopathology, 37-3 (August 2025)  

Public ISBD [article]  inDevelopment and Psychopathology > 37-3 (August 2025) . - p.1495-1504 Titre : Resting-state alterations in emotion salience and default-mode network connectivity in atypical trajectories of psychotic-like experiences Type de document : texte imprimé Auteurs : Roxane ASSAF, Auteur ; Julien OUELLET, Auteur ; Josiane BOURQUE, Auteur ; Emmanuel STIP, Auteur ; Marco LEYTON, Auteur ; Patricia J. CONROD, Auteur ; Stéphane POTVIN, Auteur Article en page(s) : p.1495-1504 Langues : Anglais (eng) Mots-clés : neuroimaging  psychosis risk  psychotic experiences  resting state Index. décimale : PER Périodiques Résumé : Social cognition is commonly altered in people with psychosis. Two main brain networks have been implicated: the default-mode network (DMN), which is associated with socio-cognitive processing, and the salience network (SN) associated with socio-affective processing. Disturbances to the resting-state functional connectivity of these networks have been identified in schizophrenia and high-risk individuals, but there have been no studies in adolescents displaying distinct trajectories of subclinical psychotic-like experiences (PLEs). To address this, the present study measured SN and DMN resting-state connectivity in a unique longitudinally followed sample of youth (n = 92) presenting with typical and atypical 4-year PLE trajectories. Compared to the typically developing low PLE control group, the atypical increasing PLE trajectory displayed reduced connectivity between the SN and DMN, increased connectivity between left and right insula, and widespread dysconnectivity from the insula and amygdala. These alterations are similar to those reported in schizophrenia and clinical high-risk samples, suggesting that early detection may be useful for mapping the developmental trajectories of psychotic disorders.
