DSM-IV AD/HD: Confirmatory Factor Models, Prevalence, and Gender and Age Differences Based on Parent and Teacher Ratings of Australian Primary School Children / R. GOMEZ in Journal of Child Psychology and Psychiatry, 40-2 (February 1999)

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 40-2 (February 1999) . - p.265-274 Titre : DSM-IV AD/HD: Confirmatory Factor Models, Prevalence, and Gender and Age Differences Based on Parent and Teacher Ratings of Australian Primary School Children Type de document : Texte imprimé et/ou numérique Auteurs : R.

It also examined the prevalence rates of the three AD/HD Types, and gender and age differences. Results supported both the two- and three-factor models, with the three-factor model only slightly better than the two-factor model. Based on parent-teacher agreement, the prevalence rates were 1.6, 0.2 and 0.6% for the Inattentive, Hyperactive-Impulsive, and Combined Types, respectively. Overall, the male to female ratio was 5: 1, and boys were rated higher than girls by both parents and teachers. Age differences were minimal. The implications of the findings in relation to some of the assumptions made in DSM-IV for AD/HD are discussed.

Psychometric Properties of the Autism Spectrum Quotient: Children's Version (AQ-Child) / R. GOMEZ in Journal of Autism and Developmental Disorders, 49-2 (February 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-2 (February 2019) . - p.468-480 Titre : Psychometric Properties of the Autism Spectrum Quotient: Children's Version (AQ-Child) Type de document : Texte imprimé et/ou numérique Auteurs : R. GOMEZ, Auteur ; V. STAVROPOULOS, Auteur ; A. VANCE, Auteur Article en page(s) : p.468-480 Langues : Anglais (eng) Mots-clés : Autism Spectrum Quotient-Children's Version  Factor analysis  Factor structure  Four-factor model Index. décimale : PER Périodiques Résumé : Confirmatory factor analysis (CFA) and exploratory and factor analysis (EFA) aimed to determine the optimum Autism Spectrum Quotient-Children (AQ-Child) model. Initial CFA of parent ratings of the AQ-Child for 404 clinic-referred children with ADHD, aged between 4 and 11 years, revealed mixed/moderate support for the implied AQ-Child five-factor model and the past statistically supported four-factor model (Auyeung et al., J Autism Dev Disord 38:1230-1240, 2008). Interestingly, EFA findings indicated most support for a four-factor model, with factors reflecting "mind-reading", "social skills", "attention to details", and "imagination". The items loading in these factors were different from those proposed originally for similar factors (Auyeung et al., J Autism Dev Disord 38:1230-1240, 2008). The factors in the model showed acceptable internal consistency-reliability and discriminant validity. Clinical and research implications are discussed.
