“…In this study, we verified the diagnostic capabilities of these questionnaires for applicability in Koreans patients. The mean scores of the three questionnaires were not affected by age, symptom duration, diagnosis type, or gender and were in-line with previous studies [9,18,25]. This supports the generalized use of all three questionnaires in dysphonic patients and for a broad range of voice disorders.…”

“…And, for the K-VRQOL and K-VCI, significant correlation between the two questionnaires was reported (correlation coefficient: −0.897) [25]. Our study showed a higher correlation coefficient (−0.882) between the K-VRQOL and K-VCI, which is similar to previous research results on Koreans [25]. These results might suggest that the K-VRQOL and K-VCI are not significantly affected by cultural differences.…”

“…For the VRQOL and VCI, there was a moderate correlation (correlation coefficients: −0.562) in a previous study [18]. And, for the K-VRQOL and K-VCI, significant correlation between the two questionnaires was reported (correlation coefficient: −0.897) [25]. Our study showed a higher correlation coefficient (−0.882) between the K-VRQOL and K-VCI, which is similar to previous research results on Koreans [25].…”

“…The Korean version of the VHI (K-VHI) [10], VRQOL (K-VRQOL) [29], and VCI (K-VCI) [25] were used and all patients completed these questionnaires at the initial visit. The K-VHI included 30 items, divided into three subtypes: functional, physical, and emotional.…”

“…Many studies report that the three questionnaires are valid tools [9,18,25]. However, the validity and reliability of self-reported questionnaires do not predict the accuracy of diagnosis, case identification, risky behaviors, the patients' inner world (e.g., catastrophization), or QOL.…”

The purpose of this study was to verify the discriminative and predictive abilities of the Korean versions of the Voice Handicap Index (K-VHI), Voice-Related Quality of Life (K-VRQOL), and Voice Catastrophization Index (K-VCI) for dysphonia screening. Methods: A total of 132 and 244 subjects in the control and case groups, respectively, completed the K-VHI, K-VRQOL, and K-VCI. Using the different types of questionnaires, we tried to verify whether age, symptom duration, type of diagnosis, and gender affected the results, and analyzed the cutoff points for screening dysphonic patients. Results: The mean scores of questionnaires were not affected by factors such as age, symptom duration, type of diagnosis, or gender. All questionnaires showed a significant correlation with one another. The mean K-VHI and K-VCI scores of the case group were significantly higher than those of the control group. The mean K-VRQOL score of the case group was significantly lower than that of the control group. The cutoff points for the K-VHI, K-VRQOL, and K-VCI were 12.1, 91, and 6.1, respectively. The data showed relatively high sensitivity, specificity, and area under the curve values at each cutoff point (above 0.9), indicating excellent accuracy and a high power of discrimination. Conclusions: The cutoff points identified in our study for the K-VHI, K-VRQOL, and K-VCI for distinguishing patients with voice disorders from the control group can be used as criteria to screen for Korean dysphonic patients.
