Abstract
This study addresses the gap in literature by directly comparing the effectiveness of Intensive Comprehensive Aphasia Programs (ICAPs) and modified ICAPs (mICAPs) to usual care service delivery models for people with aphasia. Through a prospective study design, cognitive-linguistic function change scores across different service delivery models were examined. The findings reveal significant within-group improvements in cognitive-linguistic function for participants in ICAPs, with some improvement seen in mICAPs and usual care conditions. Intensive models demonstrated greater improvement compared to non-intensive usual care models, particularly evident in the Western Aphasia Battery – Revised and the Boston Naming Test – Second Edition. However, this trend was not consistent across all assessment measures, suggesting variability in outcomes. Additionally, no strong correlation was found between program intensity and cognitive-linguistic outcomes at the group level. Furthermore, the study found no significant relationship between time post-onset of aphasia and cognitive-linguistic change scores, indicating that individuals with aphasia can experience meaningful improvements regardless of chronicity. Despite efforts to mitigate limitations such as small sample size and participant variability, caution is warranted in generalizing results. Future research should explore this topic with larger, multi-site studies to further validate findings and enhance generalizability. Nevertheless, the study provides valuable insights supporting the implementation of intensive treatment approaches for people with aphasia, highlighting their potential to significantly enhance cognitive-linguistic function.
