Validity and Reliability of Korean Version of the Aging Voice Index (KAVI)

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 (α=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.

Idosas Coristas: Valores Atribuídos ao Envelhecimento / Older Choristers: Assigned Values Aging / Coristas mayores: Los valores asignados Envejecimiento

O presente trabalho teve por objetivo analisar os valores atribuídos ao envelhecimento por idosas coristas. 54 idosas participantes de corais (GC) e 25 idosas que participavam de outras atividades voltadas para a terceira idade que não envolvessem o uso da voz cantada (GNC) responderam à pergunta "O que é envelhecer". As respostas foram gravadas e posteriormente transcritas. Esse material foi submetido à "leitura flutuante" e a seguir classificado em eixos temáticos que foram descritos e submetidos à análise estatística. Pode-se concluir que as coristas atribuem valores positivos ao envelhecer, caracterizados principalmente por menor preocupação com as limitações físicas e mentais, pela aceitação das mudanças decorrentes do envelhecimento como um processo natural e de uma visão positiva sobre sua faixa etária.

This study aimed to analyze the values attributed to aging for older choristers. 54 elderly participants of corals (GC) and 25 elderly women whoparticipated in other activities for the elderly that did not involve the use of singingvoice (CNG) answered the question "What is aging." The responses were recorded and later transcribed. This material was subjected to the "floating reading" and then classified into themes that have been described and analyzed statistically. It can be concluded that the choristers attribute positive values to age, mainly characterized by less concern with the physical and mental limitations, the acceptance of the changes associated with aging as a natural process and a positive outlook on their age group.

Este estudio tuvo como objetivo analizar los valores atribuidos al envejecimiento de coristas mayores. 54 participantes de edad avanzada de los corales (GC) y 25 mujeres de edad que participaron en otras actividades para las personas mayores que no implican el uso de voz cantando (GNC) responde a la pregunta "¿Qué es el envejecimiento." Las respuestas fueron grabadas y posteriormente transcritas. Este material se sometió a la "lectura flotante" y luego clasificado en temas que han sido descritos y analizados estadísticamente. Se puede concluir que los coristas atribuyen valores positivos a la edad, que se caracteriza principalmente por la menor preocupación por las limitaciones físicas y mentales, la aceptación de los cambios asociados con el envejecimiento como un proceso natural y una actitud positiva ante su grupo de edad.
