Participants demonstrated Understanding, Making a Choice, Reasoning, and Appreciation of two medical vignettes (Drug Treatment for Dementia, and Feeding Tube Placement for Dysphagia) under two counterbalanced conditions --when presented verbally alone or verbally with visual aids. The visual aids consisted of pictures and text illustrating the two medical vignettes. Transcripts of the experimental sessions were analyzed for quality of the verbal statements made to demonstrate decisional capacity. In addition, twelve speech clinicians blinded to the experimental conditions rated participants’ decisional capabilities using a 7-point Likert scale. Results showed that participants demonstrated significantly better overall decisional capacity in Understanding, Reasoning, and Appreciation when supported by visual aids during the decision-making process. No significant differences between conditions were found for Expressing a Choice, the decisional skill Logical Sequence under Reasoning, and Acknowledgement under Appreciation. Participants generated significantly more Rewordings and Exact Statements, and significantly fewer Statements Not Mentioned, in the visual condition than in the verbal condition. In addition, participants with mild dementia produced more Rewordings, while those with moderate dementia offered more Exact Statements. Overall, clinicians’ ratings validated participants’ decision making performance on the experimental tasks; clinicians’ ratings reflected greater agreement in the visual condition, than in the verbal condition. 2015-05-28 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1429721461 http://rave.ohiolink.edu/etdc/view?acc_num=osu1429721461 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
