Abstract
 
Purpose
 

The purpose of this study was to develop a Chinese version of the Catquest-9SF Questionnaire (CHI-Catquest-9SF) and to test its reliability and validity in a group of patients with cataract in China.

 
Methods
 

The Catquest-9SF Questionnaire was translated into Chinese. Preoperative patients were recruited from Zhongshan Ophthalmic Center, and their demographic data and visual acuity were documented. Psychometric properties of the CHI-Catquest-9SF, including internal consistency, test-retest reliability, item-scale correlations and construct validity were tested.

 
Results
 

A total of 75 patients were recruited and participated in the study. The non-response rate and the floor and ceiling numbers of the CHI-Catquest-9SF were calculated. The internal consistency was high in most subscales, and Cronbach alpha ranged from 0.70-0.92. The test-retest reliability was excellent (intraclass correlation coefficient >0.89). Patients with worse visual acuity had significantly poorer scores on the CHI-Catquest-9SF. Rasch analysis showed that this version of the questionnaire had order response thresholds and was free from differential item functioning. The items fit a single overall construct and unidimensional by principal components analysis.

 
Conclusions
 

The CHI-Catquest-9SF is a reliable and valid tool for assessing the visual disability outcomes of Chinese patients with cataract, and it may be recommended for routine clinical use.
