PURPOSE: Validation of the @entity1545 Vision Symptom Survey (BIVSS), a self-administered survey for vision symptoms related to @entity131 ( @entity131 ). METHODS: A 28-item vision symptom questionnaire was completed by 107 adult subjects (mean age 42.1, 16.2 SD, range 18-75) who self-reported as having sustained mild-to-moderate @entity131 and two groups of reference adult subjects (first-year optometry students: mean age 23.2, 2.8 SD, range 20-39; and 71 third-year optometry students: mean age 26.0, 2.9 SD, range 22-42) without @entity131 . Both a Likert-style method of analysis with factor analysis and a Rasch analysis were used. Logistic regression was used to determine sensitivity and specificity. RESULTS: At least 27 of 28 questions were completed by 93.5% of @entity131 subjects, and all 28 items were completed by all of the 157 reference subjects. BIVSS sensitivity was 82.2% for correctly predicting @entity131 and 90.4% for correctly predicting the optometry students. Factor analysis identified eight latent variables; six factors were positive in their risk for @entity131 . Other than @entity892 , the @entity131 @entity1 were significantly more symptomatic than either cohort of optometry students by at least one standard deviation (p < 0.001). Twenty-five of 28 questions were within limits for creating a single-dimension Rasch scale. CONCLUSIONS: Nearly all of the adult @entity131 subjects were able to self-complete the BIVSS, and there was significant mean score separation between @entity131 and non- @entity131 groups. The Rasch analysis revealed a single dimension associated with @entity131 . Using the Likert method with the BIVSS, it may be possible to identify different vision symptom profiles with @entity131 @entity1 . The BIVSS seems to be a promising tool for better understanding the complex and diverse nature of vision symptoms that are associated with @entity1545 .
