Satisfaction of Basic Psychological Needs, Self-Determined Exercise Motivation, and Psychological Well-Being in Mothers Exercising in Group-Based Versus Individual-Based Contexts.

We compared mothers who exercised predominantly in group settings, those who exercised predominantly in individual settings, and those who exercised equally in group and individual contexts among the following: (a) satisfaction of basic psychological needs (autonomy, competence, and relatedness); (b) self-determined exercise motivation; and (c) psychological well-being. With clear implications for mothers' exercise interventions we found that exercising either predominantly in group contexts or in mixed group and individual settings was associated with mothers having significantly higher satisfaction of basic psychological needs and self-determined exercise motivation than those exercising predominantly alone.
