![]() ![]() Reliability analysis and principal component analysis supported the reduction of 1 item from the final pediatric VOS. Results The mean ± SD (range) score for the pediatric VOS was 49.8 ± 27.1 (0-100). The VOS was then revised to suit the results of this analysis. Structural properties of the instrument examined include validity, reliability, and principal component analysis. A scoring paradigm was developed to report the scores on a range of 0 to 100. The VOS was altered so that each item was addressed to the parent proxy as opposed to the child. Methods The voice outcome survey (VOS) was administered to 108 caregivers of children aged 2 to 18 years, who either had a tracheotomy or had achieved surgical decannulation. Objective To validate a parent proxy instrument to study the voice-related quality of life (VR-QOL) for the pediatric population. ![]() Shared Decision Making and Communication.Scientific Discovery and the Future of Medicine.Health Care Economics, Insurance, Payment.Clinical Implications of Basic Neuroscience.Challenges in Clinical Electrocardiography. ![]()
