To culturally and linguistically adapt the Convergence Insufficiency Symptom Survey (CISS) to Spanish and assess the psychometric performance of the new version through Rasch analysis and classical test theory methods. Methods: The Spanish version of the CISS (CISS VE) was completed by 449 subjects (9-30 years old) from the general population. The validity and reliability of CISS VE were assessed through Rasch statistics (precision, targeting, item fit, unidimensionality, and differential item functioning). To test construct validity, we calculated the coefficients of correlation between the CISS VE and the Computer-Vision Symptom Scale (CVSS17) or Warwick-Edinburgh Mental Well-Being Scale (WEMWBS). We determined test-retest reliability in a subset of 229 subjects. We used differential item functioning (DIF) to compare the CISSS VE and the CISS after administering the CISS to 216 English children. Results: After applying exclusion criteria, the responses of 420 participants (mean age, 18.62 years; female, 54.95%) revealed good Rasch model fit, good precision (person separation = 2.33), and suboptimal targeting (-1.37). There was some evidence of multidimensionality, but disattenuated correlations between the Rasch dimension and a possible secondary dimension were high, suggesting they were measuring similar constructs. No item bias according to gender or age was detected. Spearman's correlation was 0.34 (P < 0.001) for CISS VE-CVSS17 and non-significant for CISS VE-WEMWBS. The limits of agreement for test-retest reliability were 9.67 and-8.71. Rasch analysis results indicated no difference between CISS and CISS VE. Conclusions: According to our results, CISS VE is a valid and reliable tool for measuring the symptoms assessed by CISS in Spanish people 9 to 30 years of age. Translational Relevance: CISS VE can measure convergence insufficiency symptoms in Spanish-speaking subjects.

“…11 When compared to all of the existing translated and validated cataract-specific instruments in China (the Visual Function Index-14, targeting = -0.83; Catquest, targeting = 0.50; National Eye Institute Visual Functioning Questionnaire, targeting = -1.25), the HKQ demonstrated much better targeting in fact had a near perfect (item and person mean difference = -0.05) targeting. 16,17,20 This is probably because the HKQ items were specifically developed for Chinese people. This demonstrates the significance of population-specific content development in the performance of an instrument.…”

Ethnic Differences in the Association Between Age-Related Macular Degeneration and Vision-Specific Functioning

IMPORTANCE Understanding the link between ethnicity and health is critical to making appropriate public policy decisions. Few population-level data are available about this connection, however, including the influence of ethnicity on the association between age-related macular degeneration (AMD) and vision-specific functioning (VSF). OBJECTIVE To identify the influence of ethnicity on VSF among Chinese, Malay, and Indian patients with AMD. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional, population-based study relied on patients and their data from 3 population-based studies in 3 ethnic groups: Chinese, Malay and Indian. Of 10 033 Chinese, Malay, and Indian adults who participated in the study, 9962 (99.3%) who had gradable fundus images and Visual Function Index (VF-11) data available were included in the analyses for the present study. Uniocular presenting distance visual acuity was measured using the logMAR chart. Separate multiple linear regression models examined the association between AMD and VSF in the 3 ethnic groups, adjusting for age, sex, presenting visual acuity in the better-seeing eye, educational level, income, smoking status, hypertension, diabetes, cardiovascular disease, total cholesterol level, and other eye conditions. Data were collected between
