Summary
The collaborative referencing intervention (CRI) effectively improved naming abilities in adults with chronic aphasia. This study confirms the CRI
Area of Science:
- Neurolinguistics
- Speech-Language Pathology
Background:
- Previous case studies established the feasibility of the Collaborative Referencing Intervention (CRI).
- Chronic aphasia presents persistent challenges in communication, particularly naming abilities.
Purpose of the Study:
- To replicate and investigate the efficacy of the CRI in adults with chronic aphasia.
- To assess the impact of the CRI on confrontational naming abilities using a multiple-probe single-case experimental design.
Main Methods:
- A Phase II mixed-methods study involving four adults with chronic aphasia.
- Included preparatory, baseline, intervention (CRI), and maintenance sessions.
- Utilized collaborative confrontation naming probes and assessed fidelity and social validity.
Main Results:
- Successful referential learning was observed in all participants.
- The CRI demonstrated a positive treatment effect on naming in three out of four participants.
- High fidelity and positive social validity outcomes were reported.
Conclusions:
- The CRI shows significant clinical potential for improving naming in chronic aphasia.
- Further research is recommended to explore treatment effectiveness across diverse clinical settings.
