The relationship between symbolic play and other domains, such as degree of autistic symptomatology, nonverbal cognitive ability, receptive language, expressive language, and social development, was investigated. The assessment files of 101 children with Autism Spectrum Disorder were studied. Nonverbal cognitive ability and expressive language were both significantly and uniquely related to symbolic play, although receptive language was not. Autistic symptomatology ceased to be significantly related to symbolic play when controlling for two or more other variables. Social development was related to symbolic play in those children with high nonverbal cognitive ability but not those with low nonverbal cognitive ability. The diagnostic and treatment implications of these results are discussed.
