Titre : Does maternal psychopathology bias reports of offspring symptoms? A study using moderated non-linear factor analysis Type de document : Texte imprimé et/ou numérique Auteurs : T. M. OLINO, Auteur ; G. MICHELINI, Auteur ; R. J. MENNIES, Auteur ; R. KOTOV, Auteur ; D. N. KLEIN, Auteur Article en page(s) : p.1195-1201 Langues : Anglais (eng) Mots-clés : Adolescent Bias Factor Analysis, Statistical Family Female Humans Mental Disorders/epidemiology Mothers Psychopathology Maternal bias maternal psychopathology youth psychopathology Index. décimale : PER Périodiques Résumé : BACKGROUND: Mood-state biases in maternal reports of emotional and behavioral problems in their children have been a major concern for the field. However, few studies have addressed this issue from a measurement invariance perspective. METHODS: Using data from baseline assessment of the Adolescent Brain Cognitive Development (ABCD) study (n = 8,507 mother-child dyads; youth aged 9-11 years), we examined how dimensions of maternal psychopathology, including internalizing problems, were associated with indices of bias in reports of their children's dimensions of internalizing, externalizing, neurodevelopmental, detachment, somatoform psychopathology using moderated non-linear factor analysis. Moderated non-linear factor analyses examined multiple potential biases in maternal reports of youth psychopathology. RESULTS: Across analyses, we found very small magnitudes of associations between dimensions of maternal psychopathology and biases in reports of child emotional and behavioral problems. CONCLUSIONS: Based on these results, we find little psychometric evidence for maternal psychopathology biasing reports of child behavior problems.

This study examined RRBs among 827 preschool-age children, ages 35 to 71 months, through an exploratory factor analysis of RRB items from the Autism Diagnostic Interview-Revised (ADI-R) collected through the Study to Explore Early Development. The factor structures of RRBs among children with confirmed ASD versus those with non-autism developmental concerns were qualitatively compared. Correlations between RRB factors and participant characteristics were examined in the ASD group. Three conceptually well-defined factors characterized as repetitive sensorimotor behaviors (RSMB), insistence on sameness (IS), and a novel stereotyped speech (SPEECH) factor emerged for the ASD group only. Distinct factors were supported by different clinical correlates. Findings have implications for improving differential diagnosis and understanding of ASD symptomatology in this age range.

To compare autism across cultures it is important to investigate whether the tools used are conceptually equivalent across cultures. This study evaluated the factor structure of the parent-reported Autism Spectrum Quotient Short Form in autistic children from China (n=327; 3 to 17Â years) and the Netherlands (n=694; 6 to 16Â years). Confirmatory factor analysis did not support the two-factor hierarchical model previously identified. Exploratory factor analysis indicated culturally variant factor structures between China and the Netherlands, which may hamper cross-cultural comparisons. Several items loaded onto different factors in the two samples, indicating substantial variation in parent-reported autistic traits between China and the Netherlands.

Titre : Testing a theory-driven factor structure of the autism-spectrum quotient Type de document : Texte imprimé et/ou numérique Auteurs : Yiqin ZHU, Auteur ; Wenting MU, Auteur ; Marianne G.

The current study aimed to develop a theory-driven factor structure of the AQ that would fit as well across samples as the 12 previously proposed factor structures, all of which, except for the original Baron-Cohen model, had been developed on the basis of exploratory factor analysis (EFA) or principal component analysis. We first proposed a six-factor solution: (1) social anhedonia; (2) interest in details/patterns; (3) imagination ability; (4) desire for predictability/routine; (5) social cognition; and (6) social discourse convention. We tested the six-factor structure and made final item selections (27 items) with EFA using data from college students (n = 503). Then, we empirically tested alternative factor structure models in three other independent samples (ns = 503; 1263; 1641) using confirmatory factor analysis. Results indicated that our model fit as well, if not better, than all of the other models across samples, regardless of parameter estimation methods and software packages. Overall, the theory-driven replicable six-factor structure that we report holds the potential to be used to measure the six domains of features that we identified in the AQ. LAY SUMMARY: Questionnaire measures of autism spectrum conditions have typically been used to measure approximately four broad dimensions. Our study suggests that the Autism-Spectrum Quotient can be used to measure six more narrowly defined dimensions: social anhedonia, interest in details/patterns, imagination ability, desire for predictability/routine, social cognition, and social discourse convention. Additional work is needed to develop measures of a much wider variety of autism spectrum features.

To establish the internal consistency and discriminant validity of the AEQ, parents of children with ASD (n = 105, M(age) = 40.85, SD = 15.67 months) or typical development (TD; n = 98, M(age) = 50.33, SD = 16.50 months) completed the AEQ. Questionnaire construction, content validity, factor analysis, internal consistency and discriminant validity are reported. The AEQ was reliable with high internal consistency in most domains. Significant differences were found between groups in all domains. The AEQ is a reliable and valid tool and may help to characterize eating difficulties in this population.
