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.
