Abstract:
AIM: To evaluate the applicability of Chinese dry eye questionnaire in college students using the ocular surface disease index(OSDI)questionnaire as a reference.METHODS: Cross-sectional study. A total of 711 college students from Nanyang Medical College were enrolled in the study and assessed for dry eye condition using OSDI questionnaire and Chinese dry eye questionnaire. The response rate of each question in the two questionnaires was counted. Cronbach α was calculated to evaluate the internal consistency of both questionnaires. Correlation between the total scores of the two questionnaires was analyzed to evaluate the criterion validity. Based on OSDI scores, the discriminant validity of Chinese dry eye questionnaire was evaluated; receiver operating characteristic(ROC)curves was plotted for Chinese dry eye questionnaire scores, area under the ROC curve(AUC)was calculated, and diagnostic thresholds and corresponding sensitivity and specificity were also analyzed.RESULT: The response rates of the 12 questions on the OSDI questionnaire were 33.2%-100.0%, while it was 100.0% for each question on the Chinese dry eye questionnaire. The Cronbach α values of OSDI questionnaire and Chinese dry eye questionnaire were 0.905 and 0.789, respectively. The Chinese dry eye questionnaire score was positively correlated with the OSDI score(rs=0.712, P<0.001). According to OSDI questionnaire scores, dry eye severity was divided into normal group, mild dry eye group, moderate dry eye group and severe dry eye group. The scores of Chinese dry eye questionnaire in these groups were 4.00(2.00, 6.00), 9.00(7.00, 11.00), 12.00(9.00, 14.00)and 16.00(13.50, 22.00), respectively, which increased with the severity of dry eye, and the overall difference was statistically significant(P<0.001), as well as pairwise comparison between groups(P<0.05). The AUCs of Chinese dry eye questionnaire in distinguishing normal population from dry eye population, mild dry eye from moderate dry eye, moderate dry eye from severe dry eye were 0.862, 0.661 and 0.769, respectively, and the diagnostic thresholds were 6.5, 11.5 and 14.5, respectively.CONCLUSION:Chinese dry eye questionnaire has an equivalent reliability, validity, discriminant ability and better response rate for dry eye screening and epidemiological survey among college students in China compared with OSDI questionnaire.
