Abstract: Background: Several theories and models have been proposed to explain decisions in changing and adopting
behavior but few address the intricacies of behavioral maintenance. The current study assesses the utility of
the Investment Model, which identifies satisfaction, investments, and involvement alternatives as predictors
of commitment and continued behavior, in predicting physical activity behavior. Methods: Participants (N =
267) completed questionnaires about physical activity and commitment. Structural equation modeling assessed
relationships among 2 types of exercise commitment (want to or enthusiastic commitment, have to or obligatory
commitment), 3 commitment determinants (satisfaction, investments, and alternatives), and physical
activity (minutes of physical activity, stage of behavior change). Results: Want to commitment, but not have
to commitment, was related to stage of exercise behavior change and time spent in physical activity. Satisfaction
and investments were positively related to want to commitment; whereas, satisfaction, investments, and
alternatives were positively related to have to commitment. The model explained 68% and 23% of the variance
in time spent in physical activity and stage of behavior change, respectively. Conclusions: This study provides
support for the application of the Investment Model to physical activity and suggests that want to commitment
may be important for explaining and predicting sustained physical activity behavior.
