Commitment to change: Theoretical foundations, methods, and outcomes

During the past three decades, the commitment-to-change strategy has been used to promote as well as measure behavioral change. The present inquiry stakes out theoretical foundations for the commitment-to-change strategy and identifies methods associated with its implementation for both promulgating and assessing behavioral change. Theoretical foundations of the commitment-to-change model are compared with the Innovation-Decision and Change and Learning models. Outcomes associated with all three models are linked to corresponding methods of assessment.
