This study is grounded in two approaches: Theory of Self-Determination (Williams, Frankel, Campbell, & Deci, 2000) and the LPAA Project Group's (as cited in Chapey, 2001) Life Participation Approach to Aphasia. The purpose of this study is to determine the overall level of agreement, and areas where agreements are more likely, on rating life interests and values between adults with aphasia and their family members and friends. Participants included five individuals with aphasia and their family members and friends asked to speak for them. The findings showed that overall agreement was low (below 80%). Unexpectedly, agreements for objective behaviors and subjective values are generally equal. Aphasia severity (percentile) and overall level of agreement (percentage) had a significant linear correlation. Further research is needed to enhance our knowledge about agreement and disagreement for ratings of life interests and values between individuals with aphasia and family members and friends.
