Preliminary Psychometric Validation of Socioemotional and Cognitive Battery Evaluations for Adults (SCEB-A) with Autism Spectrum Disorders and Severe Intellectual Disability
Résumé
Specific and validated developmental assessments centered on cognitive and socio-emotional abilities are necessary to implement personalized behavioral and functional intervention programs for adults with autism spectrum disorders (ASDs) and severe intellectual disabilities (IDs), aiming to enhance their social communication and autonomy. The Socio-emotional Cognitive Evaluation Battery (SCEB), a psychometrically validated tool created for children with ASD and developmental ages under two years, was applied to adults with ASD and substantial developmental delay, corresponding to levels inferior to 24 months of age. The goal was to describe these individuals’ cognitive and socio-emotional development profile and its heterogeneity and conduct the first psychometric analysis for validating the test. Ninety adults (59 men and 31 women with a mean age of 39 years) with ASD and severe ID were recruited from 17 medico-social services dedicated to this population. The participants were examined by trained psychologists using SCEB-A and familiar professionals using the Vineland-II questionnaire. The profile of this group of adults revealed lower developmental levels in some domains, such as expressive language, vocal and gestural imitation, and symbolic play, and higher developmental levels in spatial relations, behavior regulation, joint attention, and affective relation. Psychometric analyses demonstrated adequate inter-rater reliability and convergent and divergent validity. This novel instrument is useful and relevant for assessing this clinical population’s cognitive and socio-emotional development, enabling professionals to implement intervention programs and cognitive and social remediation.
