ABC Data records which three components of behavior events?

• A. Antecedent, Behavior, Consequence
• B. Arousal, Behavior, Consequence
• C. Action, Behavior, Situation
• D. Antecedent, Behavior, Schedule

Answer: (A)

ABC data track what happens before, during, and after a behavior. The first part is the antecedent—the event or situation that sets the occasion for the behavior. The second part is the behavior itself—the observable action. The third part is the consequence—the result that follows the behavior and can influence whether the behavior happens again. This framing helps identify how triggers and outcomes relate to the behavior, which is essential for figuring out the function of the behavior and planning effective interventions. The other options don’t fit because they replace one of these standard components with terms not used in ABC data, such as arousal, action with a nonstandard term like situation, or schedule instead of consequence.
