Objective: The objective of this investigation was to modify an existing intervention also known as Intensive Language Action Therapy (ILAT) to determine if there was an increase in expressive language in patients with mild to moderate to severe non-fluent-Broca’s aphasia. Method: Three participants were recruited for this single case design ABA investigation. The dependent variable was spoken language, specifically correct information units (CIUs), which were transcribed and analyzed. Participants engaged in a social interaction game during the intervention phase. The group intervention sessions consisted of between twelve and sixteen 60-to-90-minute sessions which included video and audio taped ILAT sessions. Results: All three participants’ data revealed significant increases in CIU’s from the baseline to intervention phase. Further, 2 of 3 participants maintained these gains during the withdrawal phase. Conclusion: The participants in this study who exhibited Broca’s aphasia demonstrated significant increases in the production of correct information units after receiving a modified version of ILAT reducing the intensity per session. Future studies should incorporate participants with additional types and severities of aphasia.
