Sport Commitment Model

The original model specifies five. Sport enjoyment -- the positive feelings from taking part -- raises commitment and is consistently its strongest driver. Personal investments (time, effort, and money already put in that would be lost by quitting) and involvement opportunities (valued experiences available only by continuing) also raise it. Social constraints -- felt social expectations or obligations to continue -- can raise it too, though in a more obligated way. Working against commitment are involvement alternatives: the more attractive the other activities a person could do instead, the lower their commitment. Each is measured by its own set of self-report items.

Motivation is a broad concept covering why people act; the Sport Commitment Model targets a specific outcome -- the resolve to continue participating -- and explains it through a defined set of determinants with predicted directions. It is also a structural, latent-variable model: each determinant and commitment itself is measured with multiple items and the relationships among them are estimated and tested, rather than asserted. And it ties directly to behavior, since commitment is meant to predict persistence and dropout. So while motivation theories describe drives in general, the Sport Commitment Model offers a measurable, testable account of what keeps a particular person engaged in their sport.

Two athletes can be equally committed on paper yet for opposite reasons: one stays because they love the sport (enthusiastic commitment), the other because they feel they have to -- obligations, sunk investments, social pressure (constrained commitment). The second-generation questionnaire work by Scanlan and colleagues drew this distinction because the two have different implications. Enthusiastic commitment, rooted in enjoyment, tends to support healthy, sustainable engagement, whereas constrained commitment can coexist with reduced well-being and burnout. Distinguishing them lets practitioners see not just how committed participants are but why, and respond appropriately to those who are persisting out of obligation rather than joy.
