Objectives: This investigation examined how Goal Contents Theory, Organismic Integration Theory, and Basic Psychological Needs Theory collectively explain well-being and behavioral outcomes related to physical activity over 6 months. Specifically we examined a model whereby changes in relative intrinsic goal contents -%26gt; changes in motivation -%26gt; changes in psychological need satisfaction -%26gt; well-being and physical activity. %26lt;br%26gt;Methods and design: Participants were 203 adults from the general population (68.00% female; M-age = 32.57 years, SD = 15.73). Two identical questionnaire packages containing assessments of goal contents, motivational regulations, basic psychological need satisfaction, indicators of well-being and physical activity behavior, separated by six months were given to participants. Residualized change scores were analyzed with path analysis. %26lt;br%26gt;Results: Results supported the hypothesized sequence of SDT. Changes in psychological need satisfaction mediated the relationship between changes in autonomous motivation and well-being. A more complex pattern of results emerged for the indirect effects of motivation and psychological need satisfaction between relative intrinsic goals -%26gt; well-being. Changes in competence satisfaction mediated the relationship between autonomous motivation and physical activity behavior. Moreover, changes in autonomous motivation through competence satisfaction mediated the relationship between relative intrinsic goals and physical activity. %26lt;br%26gt;Conclusions: Findings support a model based on 3 mini-theories of SDT and suggest that psychological need fulfillment during physical activity could be a key mechanism that facilitates increased well-being and behavior. Findings also highlight the importance of examining competence, autonomy, and relatedness independently (rather than as a composite).
