Understanding the stages of change in intervention work is one of the most practical frameworks an interventionist can carry into a family's living room. The transtheoretical model — precontemplation, contemplation, preparation, action, and maintenance — gives us a shared language for where a loved one actually is, not where the family wishes they were. When we read that location accurately, we stop fighting the current and start working with it. This article is a practitioner-to-practitioner look at how the stages of change model shapes assessment, timing, room strategy, and the way we coach families before and after the day itself.
