The Italian Version of the 25-Item National Eye Institute Visual Function Questionnaire: Translation, Validity, and Reliability
Objective To test the Italian adaptation of the 25-item National Eye Institute Visual Function Question naire ( NEI-VFQ 25 ) and to investigate its validity and reliability . Methods This prospect i ve observational study enrolled nonhospitalized patients with 1 of 5 chronic eye diseases , and a reference sample of subjects without eye diseases . Eligible participants had to be cognitively able to respond to a health status interview and be affected by 1 of the following eye conditions : senile cataract , age-related macular degeneration , glaucoma , diabetic retinopathy , and cytomegalovirus retinitis or low vision .

Reliability and validity of the Italian translation of the NEI-VFQ 25 were tested using statistical methods . Results Statistical analysis points out that the Italian version of the NEI-VFQ 25 has good validity , discriminatory power , internal consistency , and reliability . Conclusions This Italian version of the NEI-VFQ 25 shows psychometric properties comparable to those of the American version , and thus can be used in clinical research as a specific measure of quality of life in patients with chronic eye diseases
