TLDR
The VF-14 is a reliable and valid measure of functional impairment caused by cataract and provides information not conveyed by visual acuity or a general measure of health status.Abstract:
Objective: To describe the development and the performance of a brief questionnaire designed to measure functional impairment caused by cataract (the VF-14). Design: Observational cross-sectional study. Patients were recruited between July 15 and December 15, 1991. Setting: Patients were recruited from the practices of 70 ophthalmologists, located in Columbus, Ohio (N=21), St Louis, Mo (N=26), and Houston, Tex (N=23). Patients: Seven hundred sixty-six patients undergoing cataract surgery for the first time. Main Outcome Measures: Preoperative best corrected visual acuity in each eye; scores on the VF-14, a new index of functional impairment in patients with cataract; patient reports of overall trouble and satisfaction with their vision; and scores on the Sickness Impact Profile, a measure of general health status. Results: The VF-14 has high internal consistency (Cronbach's α=.85) and correlates more strongly with the overall self-rating of the amount of trouble and satisfaction patients have with their vision than do several measures of visual acuity or the Sickness Impact Profile score. The VF-14 score is moderately correlated with visual acuity in the better eye. Conclusions: The VF-14 is a reliable and valid measure of functional impairment caused by cataract and provides information not conveyed by visual acuity or a general measure of health status.read more

Development of the 25-item National Eye Institute Visual Function Questionnaire.
TL;DR: Preliminary analyses indicate that the psychometric properties of the NEI VFQ-25 are robust for the eye conditions studied; this suggests that the measure will provide reproducible and valid data when used across multiple conditions of varying severity.

TL;DR: The NIH-TB Cognition Battery is intended to serve as a brief, convenient set of measures to supplement other outcome measures in epidemiologic and longitudinal research and clinical trials and will provide a “common currency” among researchers for comparisons across a wide range of studies and populations.

Psychometric properties of the National Eye Institute Visual Function Questionnaire (NEI-VFQ). NEI-VFQ Field Test Investigators
TL;DR: Estimates of internal consistency and test-retest reproducibility indicate that the 51-item NEI-VFQ is reliable and valid and should be a useful tool for group-level comparisons of vision-targeted, health-related quality of life in clinical research.

The routine use of patient reported outcome measures in healthcare settings.
TL;DR: In this article, the authors provide a guide for individuals who are interested in using patient reported outcome measures at a local level, however, a number of pitfalls await clinicians with limited expertise.

TL;DR: Data from this study allow further understanding of the etiology and impact of eye diseases in this ethnic group and provide population-based data on the prevalence of and risk factors for age-related eye disease in people of Malay ethnicity in Singapore.

Coefficient alpha and the internal structure of tests.
TL;DR: In this paper, a general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of a test, therefore an estimate of the correlation between two random samples of items from a universe of items like those in the test.
