Summary
Objective/Hypothesis
To verify the relationship between common mental disorders (CMDs) and the Voice Handicap
Index (VHI) in elementary school teachers from municipal schools. The VHI mean scores
in the group of teachers with symptoms of mental disorder were significantly higher
than those in the group of teachers with no symptoms in the total scores of three
subscales: disability (functional domain), handicap (emotional domain), and impairment
(organic domain).
Design
An observational cross-sectional, quantitative study was conducted in the public schools
of urban and rural areas of the city of Pelotas.
Method
A total of 575 teachers participated. Vocal handicap was measured using VHI, producing
a total score and three subscales, including emotional, functional, and organic domains.
The Self-Reporting Questionnaire, 20 items scale was used to measure mental disorder
symptoms. A log transformation was used, followed by linear regression, to evaluate
the relationship between the independent variables and the outcomes.
Results
Teachers with CMD symptoms and who took a sick leave from teaching because of voice
problems obtained the lowest scores in VHI (P<0.050). Emotional, functional, and organic voice handicap scores were significantly
higher in teachers with CMD symptoms (P<0.001).
Conclusions
A close association between voice problems and mental disorders was identified based
on the statistically significant association between high levels of voice handicap
and the mental disorders.
