Abstract
Introduction: Exploratory factor analysis of the Functional Outcome Questionnaire for Aphasia (FOQ-A) revealed two factors. We sought to determine the item level psychometrics of the two-factor FOQ-A using Rasch analysis and develop computer scoring to enhance its clinical utility. Method: 127 FOQ-A caregiver ratings were retrieved from an approved research database and analyzed using Winsteps. Results: The two-factor FOQ-A demonstrated sound psychometric properties. Item difficulty/person ability were calibrated on interval scales. Conclusions: Results provide further evidence for the FOQ-A’s validity. Item difficulty calibrated on interval scales provide guidance for treatment planning and computer scoring allows efficient documentation of functional change.
