Minimal Clinically Important Differences in CAPE-V Auditory–Perceptual Ratings of Voice Quality

This study represents the first known attempt to establish MDC and MCID thresholds for auditory-perceptual ratings of voice quality. The thresholds provide guidance for determining whether real and meaningful changes in voice quality have occurred in patients undergoing treatment for phonotraumatic voice disorders. Future research should explore these values across various voice disorder populations and severity levels and incorporate patient-reported outcomes as anchors to enhance clinical decision making and treatment outcomes in voice rehabilitation.
