The Associations Between Dispositional Mindfulness, Sense of Control, and Affect in a National Sample of Adults.

Objectives: The present study examined factors associated with better affective experiences across the life span, extending existing research to older adults. Specifically, we investigated dispositional mindfulness and sense of control as predictors of affect and sense of control as a potential mediator of the mindfulness-affect associations.

Method: We hypothesized that dispositional mindfulness mediated by sense of control would predict affective outcomes. An archival analysis of a sample of 4,962 adults, aged 28 to 84 years, was conducted using the Midlife in the U.S. national survey (MIDUS-II). Exploratory analyses were conducted with age as a moderator in all associations.

Results: Greater dispositional mindfulness predicted more positive and negative affect irrespective of age. Dispositional mindfulness did not predict sense of control. Greater sense of control predicted more positive and less negative affect, and these associations were significantly moderated by age. Sense of control did not mediate the dispositional mindfulness-affect associations.

Discussion: The present study extends existing research on the dispositional mindfulness-positive affect association to older ages. The sense of control and positive and negative affect associations are enhanced and buffered, respectively, at older ages, indicating that the association between control and affect differs by age.
