The model assumes that although the amount of time an individual spends in a specific stage varies, everyone has to accomplish the same stage-specific tasks in order to move through the change process (Prochaska & Prochaska, 2009). There is an unofficial sixth stage that is variously called "relapse," "recycling," or "slipping" in which an individual reverts to old behaviors. Examples include having a beer after a period of sobriety, or smoking a cigarette a year after quitting. Slipping is so common that it is considered normal. Social Workers are encouraged to be honest with clients about the likelihood of backsliding or reverting to old behaviors once the change process has started, not because we expect our clients to fail, but because it normalizes the experience and takes away some of sense of failure and shame.
