Parsing neurodevelopmental features of irritability and anxiety: Replication and validation of a latent variable approach / Elise M. CARDINALE in Development and Psychopathology, 31-3 (August 2019)

Elucidating how these two forms of emotion dysregulation relate to perturbed neurodevelopment may benefit from alternate phenotyping strategies. One such strategy applies a bifactor latent variable approach that can parse shared versus unique mechanisms of these two phenotypes. Here, we aim to replicate and extend this approach and examine associations with neural structure in a large transdiagnostic sample of youth (N = 331; M = 13.57, SD = 2.69 years old; 45.92% male). FreeSurfer was used to extract cortical thickness, cortical surface area, and subcortical volume. The current findings replicated the bifactor model and demonstrate measurement invariance as a function of youth age and sex. There were no associations of youth's factor scores with cortical thickness, surface area, or subcortical volume. However, we found strong convergent and divergent validity between parent-reported irritability and anxiety factors with clinician-rated symptoms and impairment. A general negative affectivity factor was robustly associated with overall functional impairment across symptom domains. Together, these results support the utility of the bifactor model as an alternative phenotyping strategy for irritability and anxiety, which may aid in the development of targeted treatments.

Practitioner Review: The assessment of bipolar disorder in children and adolescents / Argelinda BARONI in Journal of Child Psychology and Psychiatry, 50-3 (March 2009)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 50-3 (March 2009) . - p.203-215 Titre : Practitioner Review: The assessment of bipolar disorder in children and adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Argelinda BARONI, Auteur ; Ellen LEIBENLUFT, Auteur ; Kenneth E. TOWBIN, Auteur ; Jessica R. LUNSFORD, Auteur ; David A. LUCKENBAUGH, Auteur Année de publication : 2009 Article en page(s) : p.203-215 Langues : Anglais (eng) Mots-clés : Bipolar-disorder severe-mood-dysregulation mania diagnosis-assessment Index. décimale : PER Périodiques Résumé : Background: An increasing number of youth are being diagnosed with, and treated for, bipolar disorder (BD). Controversy exists about whether youth with non-episodic irritability and symptoms of attention deficit hyperactivity disorder (ADHD) should be considered to have a developmental presentation of mania. Method: A selective review of the literature related to this question, along with recommendations to guide clinical assessment. Results: Data indicate differences between youth with episodic mania and those with non-episodic irritability in longitudinal diagnostic associations, family history, and pathophysiology. In youth with episodic mania, elation and irritability are both common during manic episodes. Conclusions: In diagnosing mania in youth, clinicians should focus on the presence of episodes that consist of a distinct change in mood accompanied by concurrent changes in cognition and behavior. BD should not be diagnosed in the absence of such episodes. In youth with ADHD, symptoms such as distractibility and agitation should be counted as manic symptoms only if they are markedly increased over the youth's baseline symptoms at the same time that there is a distinct change in mood and the occurrence of other associated symptoms of mania. Although different techniques for diagnosing comorbid illnesses have not been compared systematically, it appears most rational to diagnose co-occurring illnesses such as ADHD only if the symptoms of the co-occurring illness are present when the youth is euthymic.
