OBJECTIVE: To evaluate the reliability and validity of the National Eye Institute Refractive Error Quality of Life Instrument (NEI-RQL-42) and the Refractive Status and Vision Profile survey (RSVP). METHODS: Eighty-one @entity1 with good visual acuity (better than 20/30 best-corrected acuity in each eye) completed the NEI-RQL-42 and RSVP on 2 occasions. Noncycloplegic, subjective refractions and high-contrast visual acuity assessments were also performed. Statistical analyses addressed internal consistency, test-retest reliability, and validity (ie, concurrent and construct validity) of the 2 instruments. OUTCOME MEASURES: The NEI-RQL-42, RSVP survey, subjective refraction, and visual acuity. RESULTS: The internal consistency for the overall NEI-RQL-42 was excellent (Cronbach alpha = 0.91); and for the overall RSVP, good (Cronbach alpha = 0.81). Likewise, the test-retest reliability for the overall NEI-RQL-42 was excellent (intraclass correlation coefficient [ICC], 0.91; 95% limits of agreement, -9.1 to 10.1); and for the RSVP, fair (ICC, 0.76; 95% limits of agreement, -12.1 to 12.5). The NEI-RQL-42 overall score showed good concurrent validity as it correlated significantly with subjective refraction, whereas the RSVP overall score did not. The NEI-RQL-42 and RSVP showed similar construct validity in terms of @entity2516 , but the NEI-RQL-42 showed better construct validity when discriminating by the type of refractive correction used by @entity1 . Between-instrument convergent and divergent validity was good. CONCLUSIONS: The NEI-RQL-42 and RSVP generally have good reliability and validity in this sample of @entity1 with @entity2516 . However, other factors such as content should be considered in choosing 1 of these instruments for studies of @entity2516 .
