BACKGROUND: Many parents are insufficiently active. Further research is needed to understand the goals that drive sustained exercise participation among parents. The purpose of this study was to use self-determination theory derived constructs to examine the relationship between parents' exercise goals and their autonomous motivation, controlled motivation, and exercise behavior across 1 year.
METHODS: Mothers (n = 226) and fathers (n = 70) of children less than 16 years completed the Exercise Motivations Inventory-2 and, 1 year later, the Behavioral Regulation in Exercise Questionnaire-2 and Godin Leisure-Time Exercise Questionnaire. Linear mixed effects models were used to examine the longitudinal relationships between exercise goals and autonomous motivation, controlled motivation, and leisure-time exercise.
RESULTS: All goals except weight management were significantly associated with autonomous motivation, whereas only weight and appearance goals predicted controlled motivation. Exercising for stress management and revitalization, but not health- or appearance-related goals, was significantly related to exercise behavior over 1 year.
CONCLUSIONS: Only goals related to immediate affective outcomes were associated with both autonomous motivation and exercise behavior over time. These findings support recent calls to "rebrand exercise" as a means to improve daily well-being. Such goals may drive parents to prioritize exercise because they value the immediate benefits it provides.
