Same-day, cross-day, and upward spiral relations between positive affect and positive health behaviours.
Journal Article (Journal Article)
ObjectiveThis project investigated same-day and lagged (i.e., from one day to the next) associations between daily positive affect and three distinct positive health behaviours: physical activity, fruit and vegetable intake, and meditation. Cross-day analyses also examined the role of positive affect felt during the targeted health behaviours.
DesignSecondary data analyses used a 9-week daily diary study in which midlife adults (N = 217) were randomized to learn one of two contemplative practices (i.e., mindfulness meditation or loving-kindness meditation) while reporting nightly on their emotions and health behaviours.
ResultsResults of same-day analyses revealed positive associations, both between-person and within-person, for the three positive health behaviours with daily positive affect. Results of lagged analyses revealed that positive affect experienced during fruit and vegetable intake on a given day predicted next-day fruit and vegetable intake, and that fruit and vegetable intake on a given day predicted next-day positive affect.
ConclusionThe observed same-day relations between daily positive affect and engagement in positive health behaviours illuminate one path through which positive affect may contribute to health. The observed cross-day relations reveal a need for interdisciplinary research on mechanisms through which fruit and vegetable intake may shape next-day positive affect.
