Developmental profiles were evaluated by means of a standardized tool widely used for the assessment of psychomotor development in early childhood, the Griffiths III scales, recently adapted and standardized for the Italian population. Specifically, we compared the Griffiths III profiles of children with ASD and DD (ASD+DD) with those of children with DD alone. Moreover, we inspected the psychometric function of single items by comparing children with ASD+DD and children with DD with typically developing (TD) children from the Griffiths III normative sample. In this way, we aimed to isolate the effects of each diagnostic class on psychomotor abilities and on the psychometric function of single items. The ASD+DD and DD groups were found to share the presence of lower age equivalent scores relative to their chronological age in all the developmental domains considered: Foundations of Learning, Language and Communication, Eye and Hand Coordination, Personal-Social-Emotional and Gross Motor Skills. However, the DD group displayed a homogeneous profile with similar levels of delay in all developmental domains, while children with ASD+DD exhibited relative weaknesses in the Language and Communication and Personal-Social-Emotional scales. The analysis of the psychometric function drawn for each item has confirmed different profiles in social-communicative and non-verbal items between the two diagnostic groups and in relation to TD normative sample. The Griffiths III is a valid psychometric tool for identifying atypical developmental profiles and its use may be recommended during the diagnostic process of ASD and DD, to detect specific strengths and weaknesses and guide person-centered treatment.

No evidence for a core deficit in developmental dyscalculia or mathematical learning disabilities / Irene C. MAMMARELLA in Journal of Child Psychology and Psychiatry, 62-6 (June 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-6 (June 2021) . - p.704-714 Titre : No evidence for a core deficit in developmental dyscalculia or mathematical learning disabilities Type de document : texte imprimé Auteurs : Irene C. MAMMARELLA, Auteur ; Enrico TOFFALINI, Auteur ; Sara CAVIOLA, Auteur ; Lincoln COLLING, Auteur ; D. SZÅ°CS, Auteur Article en page(s) : p.704-714 Langues : Anglais (eng) Mots-clés : Bayes Theorem  Child  Dyscalculia/diagnosis  Humans  Learning Disabilities/diagnosis/epidemiology  Mathematics Index. décimale : PER Périodiques Résumé : BACKGROUND: Two hypotheses were tested regarding the characteristics of children with mathematical learning disabilities (MLD): (a) that children with MLD would have a 'core deficit' in basic number processing skills; and (b) that children with MLD would be at the end of a developmental continuum and have impairments in many cognitive skills. METHODS: From a large sample (N = 1,303) of typically developing children, we selected a group definable as having MLD. The children were given measures of basic number processing and domain-general constructs. Differences between the observed sample and a simulated population were estimated using Cohen's d and Bayes factors. Receiver operating characteristic curves were plotted, and the area under the curve was computed to ascertain the diagnostic power of measures. RESULTS: Results suggest that the differences between the MLD and control group can be defined along with general characteristics of the population rather than assuming single or multiple 'core deficits'. None of the measures of interest exceeded the diagnostic power that could be derived via simulation from the dimensional characteristics of the general population. CONCLUSIONS: There is no evidence for core deficit(s) in MLD. We suggest that future research should focus on representative samples of typical populations and on carefully tested clinical samples confirming to the criteria of international diagnostic manuals. Clinical diagnoses require that MLD is persistent and resistant to intervention, so studies would deliver results less exposed to measurement fluctuations. Uniform diagnostic criteria would also allow for the easy cross-study comparison of samples overcoming a serious limitation of the current literature.
