Which data collection method involves noting events and their antecedents and consequences?

• A. ABC data
• B. Event recording
• C. Interval recording
• D. Duration recording

Answer: (A)

ABC data collection is about understanding why a behavior happens by tracing what happens before and after it. In this method you record the antecedent (the event or situation that occurs before the behavior), the behavior itself, and the consequence (what follows after the behavior). Keeping track of these elements across multiple occurrences lets you spot patterns and infer the function of the behavior, such as seeking attention, escaping a demand, or obtaining a desired item. Other data methods focus on different aspects. Event recording logs each instance of the behavior but doesn’t systematically capture what happened before or after. Interval recording checks whether the behavior occurs within set time blocks, without detailing the exact sequence of events. Duration recording measures how long the behavior lasts, not the surrounding context. Because ABC data explicitly ties behavior to its antecedents and consequences, it is the best match for identifying functional relationships.
