Abstract
Purpose. To test the validity-related evidence of a child and a parent symptom survey developed by the Convergence insufficiency and Reading Study (CIRS) group. Methods. A case comparison method was used to measure differences in symptoms between 14 school-aged children (ages 8 to 13 years) with Convergence Insufficiency (CI) and 14 children with normal binocular vision (NBV), Results, A pooled t-test indicated that CI children and their parents scored higher than the NBV children and their parents on the child's survey (p < 0.001) and parent's survey (p < 0.001), respectively. CI children also scored significantly higher (p < 0.03) on the Conners' Rating Scale for Parents. Conclusions. The results suggest that the CIRS symptom survey is a valid instrument for differentiating CI children from those with normal binocular vision. Additionally, children in this age group were able to respond to a broad range of symptom questions associated with CI.This publication has 2 references indexed in Scilit:
