Development and validation of the dysarthria impact scale: a patient-reported outcome for motor speech disorders
Key Points
The goal is to develop and validate a scale that measures how dysarthria affects quality of life.
Development of the Dysarthria Impact Scale (DIS) as a patient-reported outcome measure.
Validation of the DIS through reliability and practical application tests.
Assessment of the scale’s responsiveness over time.
The DIS is shown to be valid and reliable in measuring dysarthria impact.
Demonstrates practical use for patients with motor speech disorders.
Abstract
The DIS is a valid, reliable, and practical PRO for quantifying the impact of dysarthria on quality of life. Longitudinal responsiveness remains to be established.
