Which intervention strategy focuses on modifying events before a behavior occurs?

The correct answer highlights the framework of antecedent interventions, which are specifically designed to address and modify events that occur prior to a behavior. This strategy is directed at altering the context or conditions that lead to the behavior, with the aim of preventing the undesired behavior from occurring altogether. For instance, antecedent interventions may include modifying the environment, providing prompts, or altering the instructions given to a learner to decrease the likelihood of problem behaviors.

This approach emphasizes proactive measures that can reduce triggers for negative behaviors. By identifying and changing antecedent factors, practitioners can create a more favorable environment that encourages positive behavior before it is even initiated.

Interventions focused on subsequent events or consequences do not address the precursors to behavior, making them reactive rather than proactive. Feedback interventions typically aim to provide responses after a behavior occurs, further emphasizing the distinction between managing antecedents and responding to consequences. Therefore, antecedent interventions specifically target the modifications that can be made prior to behavior manifestation, making this choice the most appropriate in the context of behavior modification.
