Effects of a conservative in-patient voice treatment on the voice-related self-concept.

PURPOSE: Observational study to determine if the voice-related self-concept as measured via the Fragebogen zur Erfassung des Stimmlichen Selbstkonzepts FESS (questionnaire for the assessment of the voice self-concept) can be improved through in-patient voice therapy.

METHODS

234 female and 80 male patients that underwent an intensive 3- to 4-week in-patient voice treatment due to varying types of dysphonia. After imputation of missing items but not missing questionnaires, 255 patients were eligible for FESS evaluation, 313 for VHI-12 evaluation. The German questionnaire for the assessment of the voice self-concept (FESS) and the German 12-item short-form of the Voice Handicap Index (VHI-12) were administered at the beginning and at the end of the hospital stay. Before-after comparisons are made visually and via t test.

RESULTS

The Voice Handicap was significantly reduced, demonstrating the effectiveness of the administered therapy. Of the three scales of the FESS, the relationship with one's own voice and the awareness of the use of one's own voice was increased and thus improved. The connection between voice and emotional changes decreased significantly but only slightly.

CONCLUSION

Conservative voice rehabilitation can not only reduce the voice handicap, but also improve the voice self-concept and the results can be measured.
