Development and Evaluation of a Chinese Version of the Adult Strabismus Questionnaire (AS-20)

Abstract

The CAS-20 presented satisfactory reliability and validity in our study. It is suggested that the questionnaire can be applied in clinical trials or research for Chinese patients with strabismus.

Development of a Persian Version of the Adult Strabismus Questionnaire and Evaluating the Effect of Strabismus Surgery on Health-Related Quality of Life

“…[1][2][3][4][5][6][7][8][9][10][11][12] In some studies on the AS-20 that were done in Western societies, the median age of the patients was about twice our patients' median age. 1,4,9 This finding may reflect that strabismus cases in our country want surgical correction at a lower age.…”

“…5 In addition, Yu and colleagues developed another Chinese version with satisfactory psychometric properties. 6 However, both studies evaluated only preoperative cases. 5,6 The psychometric characteristics of the Persian version of AS-20 were evaluated in our study.…”

“…6 However, both studies evaluated only preoperative cases. 5,6 The psychometric characteristics of the Persian version of AS-20 were evaluated in our study. The test-retest reliability of our version was high (like the original scale), 7 demonstrating consistency of the responses in assessment of the patients with strabismus.…”

“…10 This study was one of the few studies to try to develop a non-English version for the AS-20. 5,6 In 2013, Wang and colleagues developed a Chinese version for the AS-20. 5 Their version had excellent reliability and validity.…”

“…1 This questionnaire was not applicable in our country due to cultural and language differences. In addition, most studies on the AS-20 assessed preoperative cases, [1][2][3][4][5][6][7][8] and only few of them evaluated postsurgical HRQOL in the patients with strabismus. [9][10][11][12] In this study, we developed a Persian version of the AS-20 and used the new questionnaire to evaluate the effect of strabismus surgery on HRQOL.…”
