Speech-language pathology researchers have pursued strategies to identify children with developmental apraxia of speech (DAS) in an effort to study the characteristics, possible cause(s), assessment, and interventions for this disorder. Increasingly, reports indicate that children with DAS experience a range of speech, language, social interaction, behavioral, and academic delays and disabilities. Measures of communication and related skills were obtained from 36 children identified with DAS. The test scores obtained were subjected to statistical analyses, and profiles based on co-occurring characteristics of these children were described. Cluster analysis indicated that four clusters of co-occurring characteristics described this group of children with DAS. A linear discriminant analysis served to identify two significant discriminant functions, with a large effect size. The discriminant functions contained variables instrumental in assigning children with DAS to the four clusters. One group of discriminating variables contained characteristics primarily associated with language, vocabulary, and behavior. The other group of discriminating variables contained characteristics associated with articulation, percent of consonants correct, and intelligibility. Knowledge of cluster characteristics should provide clarification regarding appropriate intervention techniques for children with these disorders.
