Similarly, increases in instrumental self-maintenance activity were related to decreases in mortality from all causes, respiratory disease, and senility.
Mortality due to cardiovascular disease, cancer, or senility did not differ significantly among the instrumental self-maintenance activity groups.
Therefore, it seems important, even in the very old, to improve functional capacity or instrumental self-maintenance activities in order to extend their lifespan.
The TMIG-IC consisted of 13 multidimensional items classified under three subscales of instrumental self-maintenance, intellectual activity and social role.
Senility mortality was also associated with instrumental self-maintenance activity and intellectual activity, but was not associated with total functional capacity or social roles activity.
A score for each subscale of this index was also used to measure the capacity levels of instrumental self-maintenance, intellectual activity, and social roles.
Both public choice and Taylorist principles assume workers have an instrumental, self-interested motivation; they do not account for the fact that people may act morally or ethically.
This possibility is supported by prior reports that instrumental self-care deficits begin early in dementia and basic self-care deficits increase with dementia severity.
There was no association between cancer mortality and any score groups for total functional capacity, instrumental self-maintenance activity, intellectual activity, or social roles activity.
No association was found between cardiovascular mortality and the scores of total functional capacity, instrumental self-maintenance activity, intellectual activity, and social roles activity (Table 3).
We found stronger associations between mortality due to respiratory disease or senility and total functional capacity or instrumental self-maintenance activity compared to those between mortality due to cardiovascular disease or cancer and total functional capacity or instrumental self-maintenance activity.
