TRANSLATION AND VALIDATION OF THE EUROPEAN ORGANIZATION FOR RESEARCH AND TREATMENT OF CANCER QUALITY OF LIFE QUESTIONNAIRE - INFORMATION MODULE (EORTC QLQ - INFO25) IN VIETNAMESE

為了解決Anova Precision Cook的問題，作者Son Nguyen 這樣論述：

Background: Cancer patients in Vietnam reported suffering from lacking health-related information and dissatisfaction with the information they had received to build their quality of life. Thus, a robust and easily used tool is needed to measure information needs and information satisfaction in cli

nical practice routinely. Up to date, however, no Vietnamese tool is available to measure cancer patients' information needs and information satisfaction.Objective: The study aims to translate the EORTC QLQ-INFO25 from English to Vietnamese and validate the translated instrument in the cancer popula

tion in Vietnam.Method: This cross-sectional study included two phases: phase 1 is translating the EORTC QLQ- INFO25 questionnaire from English to Vietnamese, and phase 2 is psychometric testing of the Vietnamese version of the questionnaire in terms of validity (content; criterion-related; and cons

truct validity, including exploratory factor analysis, convergent, discriminant, and known- group validity); reliability (internal consistency and test-retest reliability); and responsiveness to change in a Vietnamese cancer population. All the participants were invited to complete a set of four que

stionnaires: Basic demographic sheet, QLQ-INFO25, IN-PATSAT32, and QLQ-C30. To assess the test-retest reliability of the translated questionnaire, 53 participants answered the QLQ-INFO25 questionnaire at baseline and after three weeks. Statistical analysis was performed using SPSS version 22.0 softw

are. A p-value < .05 was considered statistically significant. Categorical variables were presented as frequency and percentage, and continuous variables were described as the mean and standard deviation. The student's t-test compared the means between two groups, whereas ANOVA compared the means am

ong three or more groups. Pearson correlation coefficient was used to calculate correlations between two continuous variables.Correlation coefficient analysis and exploratory factor analysis explore the instruments' construct validity.Results: The EORTC QLQ-INFO25 Vietnamese version performed fair t

o good on validity, reliability, and responsiveness to change tests. The content validity was good with CVI = 1. The discriminant validity was executed well, with most of the tested correlations between the QLQ-INFO25 and QLQ-C30 questionnaires being low (ranging from .003 to .219). The convergent v

alidity was somewhat weak; only four over eleven tested correlations between the QLQ-INFO25 and the IN-PATSAT32 questionnaires were considered strong (ranging from .319 to .443), even though most of the tested correlations were statistically significant correlation. The exploratory factor analysis s

uggested the construct of the translated questionnaire containing four subscales, explained in total of 62.17% of the variance. The internal consistency and stability reliability of the questionnaire were good to excellent for the whole questionnaire (Cronbach's alpha = .905 and ICC = .775). Finally

, the responsiveness to change of the translated questionnaire was demonstrated by the significant difference in the known group based on the time from diagnosis to the study.Conclusion: Despite some weaknesses in the psychometric testing, there is initial proof of sufficient quality and capacity of

this questionnaire to estimate the cancer patient group's level of information need and information satisfaction.
