Abstract

PURPOSE: To report initial psychometric evidence on the Measure of Early Vision Use. METHOD: Data on performance of the Measure of Early Vision Use scale were collected from 100 parents of children with cerebral palsy aged 0-12 years via online survey.

RESULTS: Principal components analysis of the 14-item parent-rated Measure of Early Vision Use revealed one component with an eigenvalue of 9.343, explaining 66.7% of variance; internal consistency was high (Cronbach's α = 0.96). Total scores ranged from 15-56 (Mean 42.8, standard deviation ..
