Psychometric Validation of the National Eye Institute Visual Function Questionnaire — 25 (NEI VFQ-25) French Version
Abstract Objective : Physicians need reliable , valid and sensitive question naires to assess QOL related to glaucoma or ocular hypertension . This article presents the psychometric properties of the French version of the National Eye Institute Visual Function Question naire — 25 ( NEI VFQ-25 ) . Methods : A mail survey was sent to 20 000 households . The survey identified 581 residents with glaucoma or ocular hypertension . Of these a r and om sample ( n = 204 ) took part in a telephone survey during which the NEI VFQ-25 was completed by eligible patients ( those taking at least one topical treatment for glaucoma or ocular hypertension on the day of the interview ) . Multi-trait analysis was performed to assess the construct validity of the question naire . Internal consistency reliability was assessed using Cronbach ’s α and the average inter-item correlation . Known groups validity was assessed by comparing patients grouped by duration of glaucoma , adjusted for age and gender . Results : One hundred and seventy-three patients participated in the survey . Analysis of convergent validity showed that all of the items in each scale correlated above 0.40 with their own scale except for the ‘ driving ’ scale . The success rate of the discriminant validity ranged from 57.1 % to 100 % except for the ‘ driving ’ scale , which was 7.1 % . Cronbach ’s α coefficients were all above 0.70 except the ‘ driving ’ score . Participants with glaucoma for less than 20 years consistently had better ‘ global ’ , ‘ near vision ’ , ‘ distant vision ’ , ‘ driving ’ , ’ social function ’ and ‘ peripheral vision ’ scores than those with disease of 20 + years duration , indicating better QOL in patients with a shorter disease duration . Conclusion : The NEI VFQ-25 is a vali date d instrument to measure vision-targeted QOL in French population s with glaucoma
