Abstract

Purpose: Family ratings of communication and social interactions represent an important source of information about people with aphasia. Because of the reliance on family/partner ratings as an outcome measure in many aphasia treatment studies and in the clinic, there is a great need for the validation of commonly used family/partner rating measures, and a better understanding of predictors of family ratings of communication. Method: The communication ability of 130 individuals with aphasia due to neurologic illness was rated by family members/partners on the Communicative Effectiveness Index (CETI; Lomas et al., 1989). Information on aphasia severity, mood, quality of life, nonverbal cognitive functioning, and various demographic factors was collected. Results: Principal component analysis confirmed a 2-factor model best represents the relationships among CETI rating items, and this model largely consists of a conversation-level ability factor. Family ratings were largely predicted by the patient’s expressive (not receptive) language but also patient self-perceived quality of communication life. Conclusions: Family/partners typically rate the effectiveness of communication based largely on expressive language, despite the fact that other aspects of the aphasia (e.g., listening comprehension) are as important for everyday communication.
