Comparison of reports of vocal abusive behaviors and stress experienced by women with and without vocal nodules
The purpose of this study was to compare self-reports of vocal abusive behaviors and psychological factors between women with and without vocal nodules. Twenty females between 18-32 years of age, 10 experimental subjects with hyperfunctional voice disorders and 10 control subjects with normal voices, served as subjects. Each subject monitored her vocal behaviors by responding to a questionnaire or "voice profile" for 3 consecutive days at 4 time periods. The targeted times were morning, afternoon, evening, and late night. It was hypothesized that speakers with vocal nodules would report more vocal abuse and increased stress than the speakers with normal voice. It was also hypothesized that vocal abuse/stress would increase systematically across the 4 time periods for the experimental subjects. Surprisingly, results indicate no differences between the groups for amount of reported vocal abuse/stress. In fact, the only significant findings were for reports of average amount of total talking time, loud talking, talking when voice was strained, and change perceived in voice quality. When regarding all subjects regardless of group, these variables were found to significantly increase across the 4 times. Thus, the results do not support the hypothesis that women with vocal nodules report more vocal abuse than women with normal voices.
