Both questionnaires provide very similar results. Thus, for clinical purposes, it seems justified to restrict oneself to using only one of the questionnaires. Whenever basic information on the patients' self perception of a voice disorder is required, the VRQOL questionnaire with only ten items may be easier to handle than the VHI questionnaire with 30 items.

The voice-related quality of life (V-RQOL) questionnaire was proposed as a disease specific measure of patients' subjective burden elicited by a voice disorder. The purpose of this study was to investigate the influence of gender and aetiology (benign organic versus functional) on V-RQOL results. Fifty-two German-speaking patients completed the questionnaire without prior information about their individual diagnosis. Results allow for the conclusion that women score lower indicating a poorer voice status. Differences between patients diagnosed with an organic or a functional voice disorder revealed no universal difference. This has to be investigated in future, especially against the degree of the voice disorder, the individual personality, health belief and social background.
