The consistency of self-reported preferences for everyday living: implications for person-centered care delivery.

Preferences are the expression of an individual's basic psychosocial needs and are related to care outcomes. The current study tested the consistency of 87 individuals' everyday preferences over 1 week, comparing responses of nursing home residents (n = 37; mean age = 82) and university students (n = 50; mean age = 20). Participants completed the Preferences for Everyday Living Inventory at baseline and 5 to 7 days later. Preference consistency was calculated three ways: (a) correlations (range = 0.11 to 0.90); (b) overall percent of exact agreement (e.g., response was "very important" at both time points) (66.1%); and (c) responses collapsed as "important" or "not important" (increase in percent agreement to 86.6%). Personal care preferences were more stable, whereas leisure activities were less stable. The groups did not have significant differences in consistency. Some preferences are more consistent than others; age and frailty do not appear to be related to preference instability.
