ABC Data Sheet and Analyzer

ABC data records three things every time a behavior occurs: the Antecedent (what happened just before), the Behavior (what the person did, described observably) and the Consequence (what happened just after). Over many entries, patterns appear that suggest why the behavior happens, which is the first step of a functional behavior assessment.

Narrative ABC notes are rich but hard to summarize. Checklist ABC data is fast but can miss detail. Our sheet combines both: pick a category from a dropdown, then add a short note. Because the categories are consistent, the workbook can count them and show, for example, that most episodes follow a demand and end with the task being removed, a pattern that points to escape.

Collect ABC data across settings and times of day, write what you saw rather than interpretations, and record every episode in the observation window, not only the large ones.
