However, no clear guidelines or tools exist for determining study eligibility with many studies relying on brief cognitive measures (e.g., MMSE). The literature suggests not all individuals with mild/moderate dementia can participate and some individuals with severe symptoms of dementia can participate. This study piloted a new measure designed to assess whether IWDs can participate in self-report data protocols. The measure consists of 10 questions that assess relatively in-tact cognitive processes hypothesized for successful participation. Example questions include: “What is your favorite holiday?” and “Give an example of a sad occasion/event”. Questions are scored as ‘correct’ or ‘incorrect’ and summed for a total score. To examine the descriptive characteristics of the measure, IWDs (n=18) completed the measure along with the MMSE and, for some IWDs (n=12), several self-report measures. Scores on the new measure ranged from 0-10, with a M=7.61; SD=2.75. MMSE scores ranged from 2-22, with a M=13.39; SD=6.47. A significant correlation (r = .86, p< .001) was found with the MMSE, indicating a high degree of relatedness but not complete construct overlap. Results also highlight the variability of the measure, with incorrect responses ranging from 3 to 6 across participants. Additional properties of the measure will be discussed along with highlighting how study findings fit with recommendations from 2020 NIA Research Summit on Dementia Care and next-steps in refinement and testing.
