Abstract

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.
