Étude des altérations du comportement auditif chez l'enfant avec autisme : mise au point d'un nouvel instrument d'évaluation, l'échelle EACAA-E (Échelle Altérations Comportement Auditif Autisme Enfant)

Abstract : Autism is a pervasive developmental disorder that affects all sensory, perceptual, cognitive, communicative, emotional and relationship to the child. Based on the autistic triad of symptoms (qualitative impairment in social interaction, qualitative impairments in communication and imagination, restricted, repetitive and stereotyped patterns of behavior, interests and activities), the definition of child's autism has long ruled the sensory characteristics which nevertheless attest to both people with autism and scientific studies. The DSM-5 has now fixed this oversight. Currently if auditory dysfunction can be identified by the clinician using validated diagnostic or behavioral tools, to our knowledge, there is no specific tool to evaluate them. The first objective of this research is to develop the Auditory Behaviour Alterations Scale for Children with Autism Spectrum Disorders (ABAA-C) for use by clinicians in children's exam situations with ASD and having the metrological required for use in clinical practice and research. The second objective is to show that alterations of the auditory behavior in children with ASD would be a particular component of autism, as independent of the degree of severity of autism and the degree of severity of mental retardation. Participant. Fifty children and adolescents with disorders of the autism spectrum and actual age between 2 and 18 years were recruited from medical and psychological care (Child and Adolescent Psychiatry, CAMSP) and included in the search after family consent. The diagnosis of autism is made from DSM 5 (retrospectively for some of them who had initially used the DSM-IV-TR) and diagnostic quantitative evaluation is performed using the CARS, the ADOS and ADI-R. The intellectual and psychological development and severity of mental retardation are evaluated using appropriate tests (PEP 3, EDEI-R, SCEB). Measurement'method. The Auditory Behaviour Alterations Scale for Children with Autism Spectrum Disorders (ABAA-C) is an original scale which was the subject of a first study (Master's degree) and a first psychometric analysis (2014 Filipova et al.) Which resulted in its final form: the scale includes 24 items covering seven dimensions of auditory sensory (oddity, fascinating, paradoxical, discomfort, hypoesthesia, hyperesthesia, difficulty). The listing of items (0 to 4) calculates an overall score and a score by dimension. The observation of the child's auditory behavior is made during a psychological examination of the development of cognition and communication. This examination can be registered. Trading on the scale behavior of items is performed at the end of the session by the examiner. A double rating by inter and intra-rater is carried out from the document videoscopic examination. Psychometric analysis indicates good homogeneity of the scale and good reliability inter and intra-rater. Preliminary earlier study also showed that ABAA-C scale is sensitive to changes induced by integrative care including T.E.D (Filipova et al. 2014). These results demonstrate the metrological qualities of the scale. Moreover, the overall score is negatively correlated to the overall development quotient, indicating the existence of a link between the severity of mental retardation and intensity alterations of the auditory behavior. By against and scores to the Auditory Behaviour Alterations Scale for Children with Autism Spectrum Disorders (ABAA-C) appear to be independent of the overall severity of autism, as assessed quantitatively by CARS. The Auditory Behaviour Alterations Scale for Children with Autism Spectrum Disorders (ABAA-C) appears as a relevant francophone clinical scale for assessing alterations in auditory behavior in children with ASD.
