A Voice Incidence Study: Portland, Oregon

The purpose of this study was to investigate the incidence of voice disorders among kindergarten and first-grade students in some schools in Portland, Oregon, during the Fall of 1974. The study was designed to determine the following information: 1) the percentage of voice disorders, 2) the percentage of each type of voice disorder, 3) the severity of each voice disorder, and 4) the percentage of males and of females exhibiting voice disorders.
The essential questions to be answered by the present study were: What is the incidence of voice disorders in a kindergarten and first-grade (approximately five to seven years of age) sample? What are the types of voice deviations? What is the severity of each voice problem? Was the incidence similar for males and females?
