Abstract

The Communication Confidence Rating Scale for Aphasia (CCRSA) was developed to measure the construct of confidence in communication abilities. Using eight items from the ASHA-Quality of Communication Life Scale, the CCRSA was developed and administered to 21 individuals with aphasia before and after therapy. Psychometric properties of the CCRSA were investigated using rating scale (Rasch) analysis. Preliminary reliability and sensitivity of the CCRSA support its use in assessing self-report of communication confidence. Results indicate that modification of the scale is warranted. Further evaluation of communication confidence is required with larger and more diverse samples.
