Treatment Fidelity in a Feasibility Trial of the Aphasia Intervention, Virtual Elaborated Semantic Feature Analysis

What is already known on this subject Monitoring treatment fidelity improves both internal and external validity. Reports of treatment fidelity from aphasia trials are increasing, but the guidance is not yet applied uniformly. What this study add to the existing knowledge This study demonstrates how treatment fidelity guidance has been applied across a range of fidelity areas to monitor and support a feasibility trial of a novel aphasia intervention. It is a rare reporting of strategies to monitor treatment enactment. What are the potential or actual clinical implications of this study? This study adds to the evidence base for the VESFA intervention, demonstrating that the intervention can be delivered faithfully to the manual. It builds on the evidence base for treatment fidelity monitoring in aphasia, broadening the strategies to improve the validity of interventions.
