Revisiting the latent structure of ADHD: is there a ‘g’ factor? / Michelle M. MARTEL in Journal of Child Psychology and Psychiatry, 51-8 (August 2010)
[article]
Titre : Revisiting the latent structure of ADHD: is there a ‘g’ factor? Type de document : Texte imprimé et/ou numérique Auteurs : Michelle M. MARTEL, Auteur ; Joel T. NIGG, Auteur ; Alexander VON EYE, Auteur Année de publication : 2010 Article en page(s) : p.905-914 Langues : Anglais (eng) Mots-clés : ADHD structural-equation-modeling development Index. décimale : PER Périodiques Résumé : Background: Attention-deficit/hyperactivity disorder (ADHD) is presumed to be heterogeneous, but the best way to describe this heterogeneity remains unclear. Considerable evidence has accrued suggesting that inattention versus hyperactivity-impulsivity symptom domains predict distinct clinical outcomes and may have partially distinct etiological influence. As a result, some conceptualizations emphasize two distinct inputs to the syndrome. Yet formal testing of models that would accommodate such assumptions using modern methods (e.g., second-order factor and bifactor models) has been largely lacking.
Methods: Participants were 548 children (321 boys) between the ages of 6 and 18 years. Of these 548 children, 302 children met DSM-IV criteria for ADHD, 199 were typically developing controls without ADHD, and 47 were classified as having situational or subthreshold ADHD. ADHD symptoms were assessed via parent report on a diagnostic interview and via parent and teacher report on the ADHD Rating Scale.
Results: A bifactor model with a general factor and specific factors of inattention and hyperactivity-impulsivity fit best when compared with one-, two-, and three-factor models, and a second-order factor model.
Conclusions: A bifactor model of ADHD latent symptom structure is superior to existing factor models of ADHD. This finding is interpreted in relation to multi-component models of ADHD development, and clinical implications are discussed.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02232.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=108
