Heterogeneity and plasticity in the development of language: a 17-year follow-up of children referred early for possible autism / Andrew PICKLES in Journal of Child Psychology and Psychiatry, 55-12 (December 2014)
[article]
Titre : Heterogeneity and plasticity in the development of language: a 17-year follow-up of children referred early for possible autism Type de document : Texte imprimé et/ou numérique Auteurs : Andrew PICKLES, Auteur ; Deborah K. ANDERSON, Auteur ; Catherine LORD, Auteur Article en page(s) : p.1354-1362 Langues : Anglais (eng) Mots-clés : Early intervention heterogeneity language impairment plasticity Index. décimale : PER Périodiques Résumé : Background Delayed, abnormal language is a common feature of autism and language therapy often a significant component of recommended treatment. However, as with other disorders with a language component, we know surprisingly little about the language trajectories and how varied these might be across different children. Thus, we know little about how and when language problems might resolve, whether there are periods of relative stability or lack of change and what periods might offer more favourable circumstances for intervention. Methods Expressive and receptive language was measured on six occasions between age 2 and 19 on a cohort of 192 children initially referred for autism. Latent class growth models were fitted to characterize the patterns of heterogeneous development. Results Latent class growth analysis identified seven classes. Between age 6 and 19, all classes tracked in parallel. Between ages 2 and 6, development was more heterogeneous with considerable variation in relative progress. In all groups, receptive and expressive language developed very largely in tandem. Conclusions The results confirmed previous analysis of children with specific language impairment where progress beyond age 6 was remarkably uniform. Greater variation was evident before this age with some groups making clearly better or worse progress compared to others. While this developmental heterogeneity may simply be a reflection of variation in preexisting and unchanging biological disposition, it may also reflect, at least in part, greater sensitivity in the early years to environments that are more or less supportive of language development. These findings contribute to the case for the importance of early intervention.

Titre : How interview questions are placed in time influences caregiver description of social communication symptoms on the ADI-R Type de document : Texte imprimé et/ou numérique Auteurs : Rebecca M. JONES, Auteur ; Susan RISI, Auteur ; Diana WEXLER, Auteur ; Deborah K. ANDERSON, Auteur ; Christina CORSELLO, Auteur ; Andrew PICKLES, Auteur ; Catherine LORD, Auteur Article en page(s) : p.577-585 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders ADI-R parent report longitudinal diagnosis Index. décimale : PER Périodiques Résumé : Background Caregiver report is crucial for the diagnosis of childhood onset psychiatric disorders, particularly autism. Three experiments were conducted to determine whether caregiver reports of past and current behaviors are affected by question timing and ordering. Methods Using the Autism Diagnostic Interview – Revised (ADI-R), two studies systematically varied the order in which caregivers were asked about behaviors. In a third study, descriptions of children's current behaviors at age 5 were compared to retrospective descriptions of behaviors at age 5 collected at age 10. Results Caregivers, who were first asked about a history of symptoms, described less severe past and present behavior than caregivers reporting current behaviors as well as caregivers reporting current and history of symptoms together. Caregivers retrospectively reported more severe behaviors for age 5 when their children were age 10 than they had when their children were age 5. Conclusions Caregivers describe past behaviors differently depending on whether they are asked about current symptoms first. Methods of caregiver reporting can influence interpretations of symptom severity with effects on diagnoses and research findings.

Titre : Predicting young adult outcome among more and less cognitively able individuals with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Deborah K. ANDERSON, Auteur ; Jessie W. LIANG, Auteur ; Catherine LORD, Auteur Article en page(s) : p.485-494 Mots-clés : Autism ASD Very Positive Outcome adult outcome longitudinal Index. décimale : PER Périodiques Résumé : Background The range of outcomes for young adults with Autism Spectrum Disorders (ASD) and the early childhood factors associated with this diversity have implications for clinicians and scientists. Methods This prospective study provided a unique opportunity to predict outcome 17 years later for a relatively large sample of children diagnosed with ASD at 2 years old. Diagnostic and psychometric instruments were administered between 2 and 19 with data from 2, 3, and 19 included in this study. Clinicians administered tests without knowledge of previous assessments whenever possible. Caregivers provided additional information through questionnaires. Results Significant intellectual disabilities at 19 were predicted by age 2 about 85% of the time from VIQ and NVIQ scores together, though prediction of young adult outcome for youths with average or higher intelligence was more complex. By 19, 9% of participants had largely overcome core difficulties associated with ASD and no longer retained a diagnosis. These youths with Very Positive Outcomes were more likely to have participated in treatment and had a greater reduction in repetitive behaviors between age 2 and 3 compared to other Cognitively Able youths (VIQ ?70) with ASD. Very Positive Outcome youths did not differ phenotypically from Cognitively Able ASD individuals at 2 but both groups differed from Cognitively Less Able individuals (VIQ 70). Conclusion Those most at risk for intellectual disabilities and ASD can be reliably identified at an early age to receive comprehensive treatment. Findings also suggest that some cognitively able children with ASD who participate in early intervention have very positive outcomes, although replication with randomized, larger samples is needed. In order to improve understanding of very positive outcomes in ASD, future research will need to identify how variations in child characteristics and environmental factors contribute to the nature and timing of growth across individuals and areas of development.
