Our work is informed through the Transtheoretical Model of intentional behavior change which considers multiple contexts that influence health behavior change.

Overview Of The Model

The Transtheoretical Model (TTM; Prochaska & DiClemente, 1983; Prochaska, DiClemente, & Norcross, 1992) is an integrative, biopsychosocial model to conceptualize the process of intentional behavioral change.  Whereas other models of behavioral change focus exclusively on certain dimensions of change (e.g. theories focusing mainly on social or biological influences), the TTM seeks to include and integrate key constructs from other theories into a comprehensive theory of change that can be applied to a variety of behaviors, populations, and settings (e.g. treatment settings, prevention and policy-making settings, etc.). Dr. DiClemente published Addiction and Change: How Addictions Develop and Addicted People Recover (2003) which goes into more detail about the develpment of the model and how to appropriately use the model in both research and clinical work.
