ABC Data
Observational data recording the Antecedent, Behaviour, and Consequence for specific incidents.
ABC data collection is a direct assessment tool where you record what happened immediately before a behaviour (Antecedent), what the behaviour looked like (Behaviour), and what happened immediately after (Consequence).
After gathering multiple ABC data points, you can begin to look for patterns. If the consequence is consistently teacher reprimands, the behaviour likely functions to access attention. This descriptive data proves essential for hypothesizing behavioural function.
Frequently Asked Questions
What is ABC data?
ABC data records what happened immediately before a behaviour (Antecedent), what the behaviour looked like (Behaviour), and what happened immediately after (Consequence). It is a direct-observation tool for spotting patterns.
How do you collect ABC data?
Record each incident in three columns — antecedent, behaviour, consequence — as it happens, using an operational definition so anyone records it the same way. The ABC data sheet generator builds a printable form.
What does ABC data tell you?
After several incidents, patterns emerge. If the consequence is consistently teacher attention, the behaviour likely functions to access attention. This descriptive data is the basis for hypothesising the function of the behaviour.
