Background and Objectives : Voice disorder is recognized as a major problem because it negatively affects the elderly's social participation and quality of life. The purpose of this study was to examine the validity and reliability of Korean aging voice index (KAVI), which assesses the quality of life related to the voice of the elderly. Materials and Method : This study was conducted on 211 elderly people aged 65 years or older : 111 patients with voice disorder (mean age 69.8, range 65-80 years) and 100 nomorphonic participants (mean age 70.6, range 65-82 years). Aging voice index was translated into Korean and used and Korean voice-related quality of life (KVQOL) was conducted to verify KAVI. The validity (item validity, concurrent validity, and construct validity) and reliability (test-retest reliability and internal consistency reliability) of KAVI. Results : The item validity (ICC=0.895) and construct validity (r=0.765) showed a high correlation, respectively. And concurrent validity (r=0.748), test-retest reliability (0.851), and internal consistency reliability (${\alpha}=0.832$) were statistically significant in voice disorder group. In addition, there was a significant difference between the voice disorder and the nomorphonic group in AVI total score. Conclusion : KAVI is a validated and reliable quality of life tool that will be useful for assessing the presence and effectiveness of interventions in clinical settings.

본 연구의 궁극적인 목적은 청력 비완전자인 노인을 위한 학습공간의 음향기준을 제시하기 위한 것이다. 사전연구로서 본 연구는 현재 운영 중인 노인 교육시설의 청취환경을 조사하고 이를 이용 중인 노인의 음성 인지성능 실태를 조사하기 위해 진행되었다. 이를 위하여, 청주시 소재 2개 노인 교육시설을 대상으로 물리적 음향성능을 측정하고 설문조사 를 실시하였다. 또한, 음절법과 단어법을 이용한 음성명료도 평가를 수행하였다. 노인을 대상으로 한 설문조사 결과 전반적인 청취환경에는 만족하는 것으로 나타났다. 배경소음, 신호대잡음비, 잔향시간, 음성전달지수와 같은 물리적 음향성능 측정 결과 대한민국 일반교실의 음향성능 기준을 만족하고 있음을 알 수 있었다. 그러나 음성명료도 평가 결과 20대 건청인에 비해 노인 그룹의 점수가 20점 이상의 차이로 월등히 낮았으며, 연령대가 높아질수록 점수 또한 낮아지는 것으로 나타났다. 따라서 현재 사용 중인 일반인 대상 교육시설의 음향성능 기준이 노인 교육시설에 적합하지 않음을 알 수 있었다.

The purpose of this study is to evaluate the prevalence of voice disorders and the Korean voice handicap index in the elderly. For this study, 169 elderly performed two types of questionnaires and vowel /a/ prolongation. Self-reported voice symptoms and the Korean voice handicap index were analyzed and acoustic voice evaluation was performed by MDVP. The results showed that the prevalence of voice disorders in the elderly are significantly higher than that of adults in self-reports. In acoustic evaluation, 32.2% of the male elderly and 40.9% of the female elderly exceeded the thresholds of Jitter (%), Shimmer (%) and NHR. In addition, Korean voice handicap index scores of the female elderly are significantly higher than those of female adults. These findings indicate the high frequency of voice disorders in the elderly and the need to focus on this group. Additional studies on the voice related quality of life for the elderly are needed.

Larynx plays an important role in phonation and protection of the respiratory tract during swallowing. The reduced anatomical and physiological function in elevation of larynx and glottis closure can cause problems in voice and swallowing. The present study investigated the Korean version of handicap index of dysphagia in elderly Koreans. Therefore, 60 normal elderly Koreans ranged from 65 to 95 and 20 normal Korean young adults aged from 20 to 25 were participated in this study to compare total (T), physical (P), functional (F), and emotional (E) index scores between two groups as well as among sub groups (60s, 70s, 80s) in elderly. For swallowing, total and sub dysphagia handicap index (DHI) scores, voice quality during /a/phonation following swallowing (saliva and water), intensity of coughing, and L-DDK were measured. The results showed that functional (P), physical (P), emotional (E) scores as well as total (T) score were significantly different between young adults and old adults in DHI(p<.05). Additionally, there was a negative correlation between total DHI score and intensity of coughing (r=-.51) as well as L-DDK (r=-.70). These findings suggest that a slow rate in vocal fold adduction and reduced intensity of coughing in the elderly affect swallowing function. Thus, recently translated Korean version of DHI may be useful as supplement in evaluating the swallowing problems in elderly people.
