Children with intellectual disabilities show deficits in cognitive abilities and adaptive behavior which increase the risk of psychopathological disorders. This exploratory study aims at delineating profiles of children based on their cognitive functioning and adaptive behaviors, and to compare them on psychopathological manifestations. A cognitive assessment and an evaluation of adaptive behaviors are conducted with 52 school-age children receiving services from a rehabilitation center for people with intellectual disabilities. Adaptive behaviors are evaluated by a special educator and a questionnaire concerning psychopathology is filled out by a parent and a teacher. Cluster analyses highlight three profiles among children: Performing, Uncooperative and Non-performing. They differ on cognitive functions, collaboration and in terms of practical abilities of adaptive behaviors. Chi-square tests show significant differences in social competences, but not in problematic behaviors, according to the viewpoint of parents and teachers. Potential explanations are provided to understand the absence of significant differences in problematic behaviors between the three profiles.
