This training offers an overview of the Stages of Change model, developed by James Prochaska, Carlo DiClemente, and John Norcross (1992). Although the Stages of Change are often associated with substance usage, the principles apply to almost any behavioral health issue. This training also addresses the complications substance use has on mental health treatment adherence and overall wellness. The model explores the modification of addictive behavior involving the progression through five defined states: pre-contemplation, contemplation, preparation, action, and maintenance. Attendees will receive a detailed explanation of each stage, practice interventions that best match where the person is at in the change process, and implement strategies to effectively respond to relapse. Strategies for working with resistance and denial, resolving ambivalence, building motivation for change, and preventing and managing relapse will be presented. Attendees will leave this workshop with a better understanding of how to match their interventions to the level of awareness and motivation to change of the people with whom they are working.
