Psychosocial impact of the teacher's voice throughout the career.

Summary It is generally accepted that vocal performance decreases with age. This decrease can be expected to be more pronounced in voice loading professions, which may lead to occupational dysphonia. The aim of this study was to investigate the course of voice complaints, experienced handicap, and absenteeism of work due to voice problems throughout the teaching years. Questionnaires were distributed among teachers of primary and secondary education, and 1875 were analyzed. The questionnaire was designed in such a way that personal aspects and questions about periods with symptoms and absence from work were included. The Voice Handicap Index (VHI) developed by Jacobson et al was sent along with the questionnaire. Surprisingly, a significant decrease of voice complaints during the career of the teachers was observed. The expectation that the percentage of teachers with a history of voice problems should experience more psychosocial impact, measured with the VHI, along their professional career could not be confirmed by this study. These results indicate that serious attention has to be paid to teachers with voice complaints. The fact that teachers in the beginning of their career complain more than in the end of their career emphasizes the importance of adequate aimed prevention programs for future teachers and for starting teachers with regard to their voice.
