Exploring Patient's Preference of Patient‐Reported Outcome Measures in Laryngeal Movement Disorders

Background Despite many available patient‐reported outcome measures (PROMs) for laryngeal movement disorders, there is a lack of patient input regarding which PROM most accurately and conveniently captures aspects related to their vocal disease. This study aimed to assess patients' preferences among a selection of voice‐related PROMs (Voice Handicap Index‐10 [VHI‐10], OMNI‐Vocal Effort Scale [OMNI‐VES], Communicative Participation Item Bank‐General Short Form [CPIB‐10], and Visual Analog Scales [VAS]) within the laryngeal movement disorder population and investigate associations between selected instruments. Methods Prior to botulinum toxin A injection, patients with laryngeal dystonia and/or essential tremor of the vocal tract were administered the VHI‐10, OMNI‐VES, CPIB‐10, and three novel VAS questions in a randomized order. Patients rank ordered the four PROMs based on the PROMs' reflection of their voice problems. Pearson's correlation coefficients evaluated pairwise associations among PROM scores. Fisher's exact test compared the preferred PROM rankings. Results Seventy patients (53 female, mean age = 60.7 years) participated. The VHI‐10 and CPIB‐10 were most preferred at 33.9% and 27.4% respectively. The OMNI‐VES and VAS scales were less favored (19.4%, each). When analyzed by age ≥60 years, the CPIB‐10 was most favored (33.3%), but for age
