Cross-cultural adaptation and validation of the Chinese Voice Handicap Index-10

OBJECTIVES/HYPOTHESIS: Recent developments in voice assessment propose the use of quality of life measurements. The Voice Handicap Index (VHI) is one of the most psychometrically robust and well-studied instruments among the various instruments for measuring quality of life. Two versions of VHI (VHI-30 and VHI-10) have been shown to be valid instruments for distinguishing dysphonic from nondysphonic individuals and also for documenting treatment effect for dysphonic patients. The VHI has been used worldwide; however, the psychometric properties of the Chinese version of VHI remains untested. This study aimed to investigate such properties of the Chinese VHI-30 and VHI-10 in the Hong Kong Chinese population. STUDY DESIGN: Psychometric analysis of the Chinese VHI-30 and VHI-10 in dysphonic patients and control subjects. METHODS: The original VHI-30 was translated into Chinese and was completed by 131 dysphonic patients and 54 nondysphonic individuals. The dysphonic patients also self-rated their dysphonic severity. RESULTS: Results showed high test-retest reliability and high item-total correlation for both Chinese VHI-30 and VHI-10. Both Chinese versions could be used to distinguish different dysphonic groups and between dysphonic and nondysphonic groups. Significant correlation was found between the VHI scores and the patients' self-rated dysphonic severity. CONCLUSION: The present study supported the original three-factorial structures of the VHI-30 and the use of the VHI for the Chinese population. It is shown that the Chinese VHI-10 is a strong representation of VHI-30 and is recommended for use in clinics because of its validity and ease of use by patients.     

The Voice Handicap Index: impact of the translation in French on the validation

The aim of this prospective investigation was to validate a French version of the Voice Handicap Index (VHI). A population of 52 normal subjects and 63 patients with voice disorders replied to the questionnaire at the day of their first consultation and ten to thirty days after the consultation (before any treatment). Reproducing the methodology of the American authors, the test-retest reliability and the internal consistency reliability were measured. The validity and the sensibility related to a non dysphonic population were also analysed. Regarding the normal subjects, the maximum scores for total score and subscale scores were 20 (total), 12 (physical), 7 (functional), 6 (Emotional). These scores are statistically different when compared with pathological subjects (p < 0.00001). Test-Retest stability of the pathological subjects was found to be satisfactory for both total score and subscale scores (r > 0.87). From this data set, the critical difference scores were derived for the VHI total score (15 points), for the physical subscale (9 points) and for the functional and emotional.subscales (6 points each). As for as the internal consistency reliability, Cronbach's alpha is correct (r > 7) for the pathological subjects. Yet, the analysis of the validity reply by reply, reveals some abnormalities. In conclusion, the validity of the French translation of the VHI is confirmed but the results prompt us to improve the quality of the translation.

Abstract：

Objective To investigate the reliability and validity of the simplified Chinese version of Epworth sleepiness scale(ESS). Methods Five hundred and eighty-five patients with suspected obstructive sleep apnea hypopnea syndrome (OSAHS) and 103 OSAHS patients who underwent operations were included in this study. The ESS was filled before polysomnography (PSG) monitoring under the direction of professional technicians. The patients who underwent operations did both PSG and ESS tests more than 6 months after operation. Fifty-one patients who underwent PSG at our hospital from July to August, 2010 were chosen to assess the ESS test-retest reliability on two separate occasions at least more than one week. Results The total Cronbach's Alpha of ESS was 0. 814. The test-retest reliability of ESS total scores was 0.679 and for each item was from 0.473 to 0.698 ( P ＜ 0.01 ). Split-half reliability was 0.817 ( P ＜ 0.01 ). In the analysis of discriminant validity with apnea hypopnea index (AHI), the ESS total scores and each item's scores had significant differences in severity in OSAHS patients and simple snoring patients( P ＜ 0.05 ), and this was also true in different degrees of lowest saturation of arterial oxygen ( LSaO2 ) patients and normal LSaO2 patients(P＜0.05). The factor analysis of construct validity showed that 4 factors were extracted.The cumulative proportion was 74.270%. The loading was higher than 0. 4 among every item. The correlation coefficiency of overall ESS scores and each item's scores was relatively high except the last item.The ESS had low consistency with clinical diagnosis(κ =0.099,P ＜0.01 ) and the predictive validity was not good (r =0.138, P ＜0.01 ). As for 103 patients who had operations, the initial assessment of total ESS scores were 15.0[10;20] ( M[P25 ;P75] ) ,and improved to 4[1 ;6] after operation. The patients who got effective results had significant difference in the total ESS scores before and after operation ( Z = - 7.528,P＜0.01) ,so was the patients who got ineffective results(Z= -4.382, P＜0.01) . Conclusions The simplified Chinese version of ESS had a good reliability and validity. It can be used to evaluate the chance of dozing in the daytime.     

The combined olfactory test in a Chinese population

OBJECTIVE: To establish an olfactory test in the Hong Kong Chinese population. STUDY DESIGN: Prospective analysis of the results of a combined olfactory test (COT) for patients with olfactory dysfunction and for normal subjects attending a secondary and tertiary ear, nose and throat centre. METHOD: Our COT was based on and modified from the Connecticut Chemosensory Research Centre test. It consisted of an odour identification test involving nine substances and a threshold test using a series of threefold dilutions of 1-butanol. From September 1998 to June 2002, 188 Hong Kong Chinese patients with olfactory dysfunction and subjects with normal olfaction were prospectively recruited. The subjects were categorized into normal, hyposmic and anosmic groups. The olfactory function of the main group of subjects (n = 153) was assessed with the COT by a blinded observer and also quantified with a visual analogue scale; the results were analysed to validate the discriminative ability of the COT. Another subgroup of subjects (n = 35) was tested with the COT twice with a two-week interval to evaluate test-retest reliability. RESULTS: There were 42 normal, 68 hyposmic and 43 anosmic subjects within the main group (total n = 153). The identification scores, threshold scores and combined olfactory scores were statistically significantly different between the anosmic, hyposmic and normal groups of subjects (p < 0.001). The combined olfactory score correlated with the visual analogue score and the correlation coefficient was 0.56 (p < 0.01). The mean time spent on each COT was 8.6 minutes (standard deviation = 3.4 minutes). The test-retest reliability of the COT was satisfactory, with a one-way model intraclass correlation coefficient of 0.87 (n = 35). CONCLUSION: The satisfactory discriminative ability and test-retest reliability of the COT have been demonstrated in this study. The COT is a feasible method for assessing sense of smell in the Hong Kong Chinese population.     

Validation and cultural modification of Arabic voice handicap index

The voice handicap index (VHI) is one of the most widely used instruments for measuring a patient’s self-assessment of voice severity. In some ways, it reflects the patient’s quality of life. Although it has been recognized and widely applied to populations in European countries and to English speaking populations, it has not been used in its present forms in the Arabic speaking countries due to the specific language constraints of Euro-American terminology. The purposes of this study were to generate an Arabic version of VHI, to assess its reliability, and to apply it to a wide variety of normal and dysphonic individuals of Arabic descent. The Arabic version of VHI was derived in the standard way for test translation. The translated version was then administered to 65 patients with voice disorders and 65 control subjects. Participants’ responses were statistically analyzed to assess the validity, and to compare the pathological group with the control group. The Arabic VHI showed a significant high internal consistency and reliability (Cronbach’s α = 0.97 and r = 0.89, respectively), high item-domain and domain-total correlation (r = 0.73–0.94). There was a statistically significant difference between the control and the voice-disordered groups (P < 0.001). The results of this study demonstrated strong internal consistency of the Arabic VHI. Thus, the Arabic version of VHI is considered to be a valid and reliable self-assessment tool for the severity of voice disorders in Arabic language speaking patients.

Throat related symptoms and voice: development of an instrument for self assessment of throat-problems

Background

Symptoms from throat (sensation of globus; frequent throat clearing; irritated throat) are common in patients referred to voice clinics and to ENT specialists. The relation to symptoms of voice discomfort is unclear and in some cases patients do not have voice problems at all. Instruments for patients' self-reporting of symptoms, and assessment of handicap, such as the Voice Handicap Index (VHI), are in common use in voice clinics. Symptoms from throat are however only marginally covered. Purpose: To develop and evaluate an instrument that could make the patients' estimation of symptoms from the throat possible. Further to facilitate the consideration of the relation between throat- and voice problems with the Throat subscale together with a Swedish translation of the Voice Handicap Index. Finally to try the VHI with the Throat subscale: the VHI-T, for test-retest reliability and validity.

Methods

A subscale with 10 throat related items was developed for appliance with the VHI. The VHI was translated to Swedish and retranslated to English. The questionnaire was tried in two phases on a total of 23+144 patients and 12+58 voice healthy controls. The reliability was calculated with Cronbach's alpha, ICC and Pearson's correlation coefficient. The validity was estimated by independent T-test.

Results

The difference in VHI-T scores between the patients and the voice-healthy controls was significant (p = < 0,01) and there was a good correlation of the test- retest occasions. The reliability testing of the entire questionnaire showed an alpha value of r = 0,90 and that for the Throat subscale separately a value of r = 0,87 which shows a high degree of reliability.

Conclusions

For the estimation of self-perceived throat and voice problems the scale on throat related problems together with the present Swedish translation of the Voice Handicap Index, (VHI) the VHI-Throat, proves to be a valid and reliable instrument. The throat subscale seems to help revealing a category of symptoms that are common in our patients. These are symptoms that have not earlier been possible to cover with the questionnaires designed for use in the voice clinic.     

Development and validation of the voice handicap index-10

OBJECTIVES/HYPOTHESIS: The objective was to develop an abbreviated voice handicap assessment instrument and compare it with the Voice Handicap Index (VHI). STUDY DESIGN: Item analysis of the VHI in individuals without voice disorders and patients with voice disorders and creation and validation of the abbreviated VHI. METHODS: Clinical consensus review of the VHI items was held to prioritize the clinical value of each of the VHI items (30 items in all). Item analysis of the VHI was performed using the VHI responses of 100 patients with voice problems and 159 control subjects. The 10 most robust VHI items were selected using the item analysis and clinical consensus results to form the Voice Handicap Index-10 (VHI-10). Statistical analysis comparing the validity of the VHI-10 with the VHI was performed with 819 patients representing a wide spectrum of voice disorders. RESULTS: Statistical analysis of the VHI and VHI-10 scores from the study group showed no statistically significant differences between the VHI and the VHI-10. Irrespective of diagnosis, the correlation between the VHI and the VHI-10 was greater than .90 (P = .01). The ratios of the VHI-10 to VHI scores for a variety of voice disorder categories were analyzed and found to be consistently greater than the expected value (33%). This suggests that the VHI-10 may be a more robust instrument than the VHI. CONCLUSION: The VHI-10 is a powerful representation of the VHI that takes less time for the patient to complete without loss of validity. Thus, the VHI-10 can replace the VHI as an instrument to quantify patients' perception of their voice handicap.
