Final answer:
Proactive behavior strategies are intended to prevent negative behavior, not to address it after it has happened. The statement in the question is false.
Step-by-step explanation:
Proactive behavior strategies are those that focus on preventing inappropriate behavior before it occurs, as opposed to responding to it after the fact. The statement that proactive behavior strategies are used after inappropriate behavior has occurred is false. Instead, proactive strategies can include setting clear rules and expectations, teaching social skills, and modifying the environment to discourage inappropriate behavior.
