The Use of Two Language Tests to Identify Pragmatic Language Problems in Children With Autism Spectrum Disorders

Purpose: Pragmatic language disorders (PLDs) are difficult to diagnose in a cost-effective manner, and there are few assessment tools that yield quantitative data. This investigation was designed to determine whether two formal assessment tools would differentiate PLDs in children with autism spectrum disorders (ASDs) from controls matched on verbal IQ and language fundamentals. Method: Thirty-four matched participants were given the Test of Pragmatic Language (TOPL; D. Phelps-Terasaki & T. Phelps-Gunn, 1992) and the Strong Narrative Assessment Procedure (SNAP; C. J. Strong, 1998). Results: Participants with ASDs had significantly poorer scores than controls on the TOPL. On the SNAP, the children with ASDs performed similarly to controls on syntax, cohesion, story grammar, and completeness of episodes. The controls performed significantly better only on the ability to answer inferential questions. Clinical Implications: The TOPL was effective in differentiating PLDs in children with ASDs when performance ...
