Description

<p>  In order to understand older adults’ life style, we compared indexes to measure the degree of older adults’ everyday activities and factors associated with the degree in terms of memory performance and memory beliefs among three age groups of Japanese adults: young, middle-aged, and older adults. Participants were asked to rate the frequency of each of 32 everyday activities (i.e., frequency index) and the importance of each of the activities for them (i.e., significance index). The frequency of each activity was multiplied by its significance rating to compute the weighted frequency index. The strongest relationship between the frequency and significance indexes was found for older adults. The statistically significant relationship was found between memory performance and beliefs measured by the Metamemory in Adulthood questionnaire only for older adults. Hierarchical regression analyses on both significance and weighted frequency indexes showed that in all age groups more than 10% of variance was accounted for by Model 3 including the metamemory subscales. However, no models explained any variance for older adults on the frequency index. These results suggest we should take into account not only the frequency but also the subjective significance of everyday activities to investigate older adults’ life style.</p>
