Theory of planned behavior and intention to exercise: effects of setting.

Objectives: To explore whether setting type (structured versus unstructured) might moderate the relationship between specific theory of planned behavior (TPB) constructs and exercise intention. It was hypothesized that perceived behavioral control (PBC) would predict intention only in an unstructured setting.

Methods: Students (N=122) completed a questionnaire that assessed TPB constructs and exercise intention for a structured (sign up) or unstructured setting (no sign up).
