Control Beliefs Mediate the Within-Person Relationship Between Everyday Activity Volition and Daily Subjective Age

ObjectivesAppraisal and interpretation of personal experiences resulting from interaction with situational contexts might play an important role in shaping subjective age at the within-person level, but it is unclear how this process unfolds. We propose that older adults evaluate situational contexts and reflect on their general psychological resources when determining their subjective age, and tested this proposal with volition of daily activities as a proxy for appraisal of situational contexts and control beliefs as a proxy for psychological resources. We hypothesize that appraising daily activities one engaged in as obligatory would deplete one’s perceived control and concomitantly make one feel older.MethodsOlder adults (n = 116) ranging in age from 60 to 90 (M = 64.84) completed a 9-day daily diary study online, resulting in 743 total days. Participants reported their sociodemographic characteristics on Day 1 and major daily activities, volition of every reported activity, felt age, and control beliefs on Days 2–9.ResultsOn days when older adults felt that activities they engaged in were of their own volition, they also felt more in control. A lower-level mediation result suggested that within-person control beliefs mediated the relationship between volition of daily activities and subjective age.DiscussionOur findings suggest that older adults evaluate situational contexts and reflect on their control beliefs as a general psychological resource when determining their subjective age. These findings show the important role psychological resources play in determining subjective age from a within-person perspective and extended the within-person process proposed in previous theoretical models.
