Critical Review: The effectiveness of script training intervention on the rate of speech and percentage content use in the speech of persons with chronic, non-fluent aphasia

This critical review examines the effectiveness of script training intervention with individuals with chronic, non-fluent aphasia with respect to improved rate of speech and percentage of script-related content words used. Study designs include: delayed treatment, multiple baseline, single subject study designs and a qualitative study. Overall, the results indicate that script training intervention produces improvements in the rate of speech and percentage of content words used in the everyday communication of individuals with aphasia. In addition to these results, findings show that generally more intensive therapy and practice of the scripts lead to greater changes in the participant's language use.
