Abstract
Older adults with mild cognitive impairment (MCI) often have difficulty performing complex instrumental activities of daily living (IADLs). Smart environment prompting technologies have gained popularity over the last decade and have the potential to assist these individuals with IADLs in order to live independently. In the current study, we developed and experimented with a graded hierarchy of prompts to examine whether individuals with MCI would benefit from receiving prompts when errors occurred during completion of eight scripted IADLs in an experimenter-assisted smart apartment environment. Thirty individuals who met criteria for multi-domain MCI, 23 individuals who met criteria for single-domain MCI, and 50 healthy older adult controls participated in this study. Results showed that the multi-domain MCI group received more prompts and required that more activity steps be prompted than the single-domain MCI and healthy older adult groups. Similar to the other two groups, the multi-domain MCI group responded accurately to the indirect prompts and did not more often need a higher level of prompting to reengage with the tasks. The total number of prompts received was best predicted by executive abilities in single-domain MCI and verbal memory abilities in multi-domain MCI. Experimenter activity quality ratings were best predicted by executive abilities in healthy older adults and individuals with single-domain MCI. These findings suggest that future IADL prompting technologies can be tailored specifically for individuals with MCI.
