Fiche synthèse

1. Objectifs


Intentions :
«Bien que le diagnostic du TSA [trouble du spectre de l’autisme] soit démontré comme étant relativement stable dans le temps, l’identification des trajectoires développementales axées sur les symptômes individuels à l’intérieur du spectre peut permettre aux cliniciens et aux chercheurs de mieux comprendre l’évolution du TSA, et de mettre en place des programmes d’intervention mieux ciblés. Cette étude est basée sur l’observation des trajectoires développementales des comportements stéréotypés et intérêts restreints chez les enfants ayant un TSA à partir du moment du diagnostic jusqu’à l’âge de 6 ans. […] Les habiletés langagières, le fonctionnement adaptif, et les niveaux de stress parentaux ont également été examinés comme prédicteurs des trajectoires des comportements stéréotypés et intérêts restreints.» (p. 6)

2. Méthode


Échantillon/Matériau :
«The data for the present project were drawn from the database of the cross-Canadian study Pathways in Autism Spectrum Disorders (e.g., Szatmari et al., 2004), a longitudinal study of developmental trajectories among persons with ASD [autism spectrum disorder] conducted in sites in Quebec, Nova Scotia, Ontario, British Columbia, and Alberta. […] 197 participants were included in the present study. The sample included 171 males and 26 females.» (p. 29)

Instruments :
- Autism Diagnostic Observation Schedule (ADOS)
- Autism Diagnostic Interview Revised (ADI-R)
- Repetitive Behaviour Scale-Revised (RBS-R)
- Vineland Adaptive Behaviour Scale-Second Edition
- Parenting Stress Index

Type de traitement des données :
Analyse statistique

3. Résumé


«Consistent with the hypotheses of the study, levels of RRBs were found to change over time from diagnosis to age 6 years. However, contrary to the predictions that were based on previous research findings of increases in the frequency and severity of RRBs over time (e.g., Richler et al., 2010; Wolff et al., 2014), overall levels of RRBs were found to decrease from baseline to Time 4.» (p. 50) «With regard to parent stress levels, change in parenting stress was found to be a significant predictor of change in overall RRBs on the RBS-R, but not on the ADI-R or the ADOS. This might be attributed to parents’ response styles on an interview as compared to a questionnaire, as parents might feel more comfortable answering questions on a questionnaire, than orally in front of an examiner. […] In contrast, parenting stress was only a significant predictor of RSM [repetitive and sensory motor], but not IS [insistence on sameness] behaviours. This might be attributed to the idea that RSM behaviours are most commonly found in lower functioning children, and since stress levels are higher among parents of children with ASD, then stress levels would logically be even higher in parents of lower functioning children.» (p. 56-57)
