Measurement Properties of the Functional Outcomes Questionnaire for Aphasia

Aphasia often results in negative social, emotional, and financial consequences endorsing rehabilitation efforts that influence communication beyond the level of impairment. The FOQ-A assesses the impact of aphasia treatment on functional communication, extending measurement into activity and participation. The purpose of this study is to evaluate the measurement properties of the FOQ-A in a sample of 127 individuals with moderate to severe aphasia subsequent to stroke. Results of Rasch analysis indicate that the FOQ-A is unidimensional, has good internal consistency, and contains adequate person separation for measuring change after rehabilitation; however, revisions to the scale may improve its usefulness.
