Welcome to part one of a larger collection on The Transtheoretical Model (also called the Stages of Change Model), developed by Prochaska and DiClemente. This week we cover the first stage of change, the precontemplation phase. In this stage, people do not intend to take action in the foreseeable future (defined as within the next 6 months). People at this time are often unaware that their behavior is problematic or produces negative consequences.
