Self-reported vision-targeted health status is measured with the Vision Function Questionnaire (VFQ-25). This interviewer or self administered questionnaire consists of a base set of 25 vision-targeted questions representing 11 vision-related constructs, plus an additional single-item general health rating question. The VFQ-25 also includes an appendix of additional items from the 51-item National Eye Institute Vision Function Questionnaire version that researchers can use to expand the scales up to 39 total items. Scoring of the VRQ-25 yields 12 sub-scale scores and an overall composite score.
