Evaluation de la symptomatologie sensorielle des personnes adultes avec autisme et incidence des particularités sensorielles sur l'émergence des troubles du comportement

Abstract : Sensorial anomalies is a major cause of disorders in the autistic spectrum as shown by their importance in diagnostic criteria of autism (DSM-5, 5, APA, 2013). There exist, however, only few validated tools that can evaluate them. This thesis aims at (1) creating a new tool, ESAA: sensorial evaluation of the adult with autism, (2) performing psychometric experiments on adult with autism that validate it, (3) classifying sensorial profiles of adults with autism and identifying potential pathological predominances of sensory, (4) evaluating the relation between the sensorial anomaly intensity and the behavior disorder. The sample of this investigation comprises 118 adults with moderate to severe autism and backwardness who were in medico-social or sanitary partner institutes. ESAA measures the sensorial reactivity of adult with autism. The intensity of sensorial reactivity is captured for each of the sensorial modalities. Behavior disorders are evaluated using EPOCAA: an evaluation scale for behavior disorders observation of adults with autism (Recordon-Gaboriaud & Granier-Deferre, ECPA, 2012). This scale allows to identify a severity level of the disorders and a behavioral typology. Results show the accuracy of the ESAA scale, distinct sensorial profiles and predominant sensorial reactivity of the considered sample. We observe correlations between subject characteristics and the severity of sensorial anomalies of the individuals. Finally, for a subset of the sample (n=27), results also indicate correlations between the severity of sensorial anomaly and the severity of behavior disorder, and between the affected sensorial modalities and the behavioral typology of the individuals. These results allow us to conclude that this new tool is useful to capture the sensorial reactivity disorders of adults with autism and backwardness and that it could contribute to (1) improve clinical knowledge of adults with autism, (2) better analyze and take into account sensorial characteristics of these individuals and (3) setup an environment tuned to their sensorial reactivity.
