It is important to examine patients' subjective evaluation as well as objective measures and clinician's rating to assess voice disorders. This study aimed to evaluate validity and reliability of Korean-version of Voice Handicap Index (KVHI) and Voice-Related Quality of Life (KVQOL) with 113 adults with voice disorders and 111 normal adults. Content validity was verified by three experienced speech-language pathologists. Concurrent validity was revealed by examining the correlation among KVHI, KVQOL, and Voice Rating Scale as well as item discrimination coefficients. Total scores of KVHI and KVQOL of adults with voice disorders were significantly different from those of normal adults. Test-retest reliability and internal consistencies were significantly high in both KVHI and KVQOL. Correlations among scores of each subscale and total score were also significantly high in each tool. The study revealed that KVHI and KVQOL are suitable tools to be used in clinics and research areas in Korea, which can subjectively evaluate the effects of voice disorders on daily life as well as on quality of life.

본 연구는 영유아 교육시설에서 근무하는 음성의 불편감을 호소하는 10명의 여성 교사들을 대상으로 반폐쇄성도훈련(semi-occluded vocal tract exercise, SOVTE)을 원격으로 실시하였을 때 주관적으로 평가하는 음성평가에 미치는 효과를 살펴보았다. 원격 SOVTE의 효과는 한국어판 음성장애지수(Korean voice handicap index, KVHI), 음성 활동 및 참여 프로파일-한국판(Korean version of the voice activity and participation profile, K-VAPP), 음성노력도 및 GRBAS를 이용한 청지각적 평가로 평가하였다. 연구 결과, KVHI의 총 점수, 기능적 점수, 신체적 점수는 원격 SOVTE를 실시한 후에 통계적으로 유의하게 낮아졌다. 원격 SOVTE 실시 후 K-VAPP의 총 점수도 유의하게 감소하였으며, 음성노력도 또한 유의하게 감소하였다. 그러나 GRB 척도는 원격 SOVTE 실시 전과 후 간에 통계적으로 유의한 차이를 보이지 않았다. 본 연구를 통해 영유아 여성 교사에게 원격으로 실시한 SOVTE는 음성의 불편감을 감소시키는데 효과적임을 입증하였으며, 원격으로 실시한 음성치료가 효과가 있음을 보여준다.

This paper will discuss the difference between self assessment of voice disorders and the hearer voice assessment of a comparative group of normal subjects. The study was conducted on 25 voice disorder subjects and 32 hearers of a comparative group of normal subjects. The results are as follows. Firstly, in K-VHI and VHI-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Likewise, in K-VQOL and VRQOL-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Secondly, the hearer voice assessment of the comparative group of normal subjects showed no difference in gender regarding the perception of the severity of voice disorder issues. Thirdly, the hearer voice assessment of the comparative group of normal subjects states that in the emotional aspects of VHI-H, professional voice users perceive more serious voice disorders than others. Accordingly, in VRQOL-H, there was no difference in use of the voice between professionals and others.
