한국어판 Penn Acoustic Neuroma Quality-of-Life Scale의 타당도 및 신뢰도 검증 = Validation of the Korean version of the Penn Acoustic Neuroma Quality-of-Life Scale

다국어 초록 (Multilingual Abstract)

Background : Quality of life (QOL) has emerged as an increasingly important factor on vestibular schwannoma (VS) treatment. There have been some literatures that have investigated the QOL of VS patients. However, there is no Korean translation of disease-specific questionnaires for VS. The objective of this study was to determine the reliability and validity of a Korean version of the Penn Acoustic Neuroma Quality-of-Life Scale (PANQOL). Methods : The development of the Korean version of PANQOL included the processes of standard independent forward translation, backward translation and reconciliation. The finalized K-PANQOL was administered to 125 patients with VS visiting 3 referral hospitals in a prospective manner. Reliability and validity were evaluated by Cronbach’s alpha coefficient, confirmatory factor analysis and test-retest analysis. Results : K-PANQOL showed good reliability with high internal consistency (Cronbach’s α = 0.939). Construct validity was confirmed by the results of factor analysis and criterion validity demonstrated positive correlations between each part of K-PANQOL and the characteristics of the patients with VS. Conclusions : Reliability, and construct validity outcomes in the current study support the validity of the Korean version of the PANQOL. The K-PANQOL seems to be a valid disease-specific measure of QOL in Korean patients with VS.
