Abstract
PURPOSE: To investigate the mediating role of psychological need satisfaction in the relationship between exercise self-schema and outcomes of well-being and physical activity. METHODS: Individuals (N = 153; 55.6% female, Mage = 41 years old, SD = 12.59) completed one online questionnaire. RESULTS: Results of the Structural Equation Modeling indicated that descriptive exercise self-schema was related to vitality, positive affect and negative affect through the mediator of psychological need satisfaction. No significant indirect effects emerged between importance exercise-self-schema and outcomes. Overall model R2’s for well-being and physical activity variables ranged from .20-.56. DISCUSSION: Descriptive and importance exercise self-schema differentially predicted psychological need satisfaction and outcomes of well-being and physical activity. Psychological need satisfaction could be one possible mechanism that is responsible for the relationship between descriptive exercise self-schema and outcomes of positive affect, vitality and negative affect.
