Description
Summary:Objective The objective of this study was to evaluate the feasibility, acceptability, and preliminary efficacy of two enhanced consent procedures provided to patients with Alzheimer disease or mild cognitive impairment that used either a PowerPoint presentation or an enhanced printed consent form. Methods Patients randomly assigned to an enhanced written consent procedure or slideshow presentation were assessed with the MacArthur Competence Assessment Tool for Clinical Research. Results Verbal reexplanation was associated with improved understanding in both conditions. Level of understanding did not significantly differ between the two consent groups, but administration time for slideshow presentation was less than that for an enhanced written consent procedure. Conclusion Enhanced consent procedures are feasible and useful for consent to research among patients with mild cognitive impairment or mild Alzheimer disease.
