Imitation and communication skills development in children with pervasive developmental disorders.
This study evaluates the correlation between failure to develop spontaneous imitation and language skills in pervasive developmental disorders. Sixty-four children between the age of 3 and 8 years were assessed using the Autism Diagnostic Interview-Revised (ADI-R), the Childhood Autism Rating Scale (CARS), and the Autism Diagnostic Observation Schedule (ADOS), as well as direct observation of imitation. The sample was subdivided into a verbal and a nonverbal group. Analysis of mean scores on the CARS "imitation" items and of ADI-R "spontaneous imitation" and "pointing to express interest" revealed a statistically significant difference between verbal and nonverbal groups, with more severe impairment/higher scores in the nonverbal than the verbal group. These results suggest that nonverbal children have specifically impaired imitation and pointing skills.
