Propuesta de tres Dimensiones Complementarias al Inventario del Espectro Autista de Rivière

Riviere’s Autism Spectrum Inventory (IDEA) was created in 1997 by Angel Riviere. Over the last 20 years, the IDEA has become a wide circulation questionnaire in Spanish-speaking countries. Due to recent changes in diagnostic criteria in new disease classification manuals (DSM-5 and ICD-11), it seems appropriate to propose some additional dimensions to the original instrument that help us to complete autism evaluation. The aim of this paper is to propose three additional dimensions to the IDEA inventory. The inventory was administered to a clinical sample of 151 participants with Autism Spectrum Disorder to assess reliability and validity of additional dimensions. High reliability coefficients in all dimensions were obtained (α > .96). Confirmatory factor analysis shows a model with appropriates goodness of fit indicators. This new proposal allows us to evaluate the classic four Autism Spectrum Disorders groups, including new aspects such as sensory modulation disorders, discrimination of sensations and emotions and motor disorders.
