A comparison of the occurrence and nature of vocal symptoms in two groups of Icelandic teachers.

Research suggests that teaching activities involve a high risk of developing voice disorders. The aim of this study is to examine the possible difference in the occurrence and nature of vocal symptoms in two groups of teachers-head teachers (N = 43), including both principals and assistant head teachers, and teachers of physical education (N = 43)--and to investigate the possible role of gender. The questionnaire results indicate that demands on the voice for P.E. teachers and head teachers are different. The findings suggest that (i) demands influence the occurrence and nature of reported vocal symptoms, (ii) that teachers of physical education are at a greater risk of developing voice problems, and (iii) that female P.E. teachers are at particular risk.
