Objective: To perform a psychometric evaluation of the Functional Outcome Questionnaire for Aphasia (FOQ-A), a 32-item instrument designed to assess the extent to which a person who has had a stroke performs several important functional communication behaviors.

Research Design: The FOQ-A was administered to family caregivers of persons with a history of left hemisphere stroke (N = 91) undergoing a comprehensive screening assessment to determine their eligibility for participation in research trials for novel stroke rehabilitation interventions.

Results: Statistical analyses provided strong support for the internal consistency reliability and the convergent and discriminant validity of the FOQ-A. An exploratory factor analysis revealed a two-factor solution, Basic Verbal Expression and Conversational Response Skills.

Conclusions: The present findings build on earlier evidence indicating that the FOQ-A has good psychometric properties and considerable promise as a measure of functional communication in aphasia rehabilitation. Future research will focus on the test-retest reliability, criterion-oriented validity, and predictive validity of the instrument.
