🧩 ABC Behaviour Record

Why this helps

When a family arrives exhausted by a child’s behaviour, they have almost always tried the obvious things — reward charts, taking things away, reasoning, shouting, and then feeling terrible about the shouting. What they usually have not done is work out what the behaviour is for. That sounds like an odd question, because in the moment it looks like pure chaos. But behaviour that repeats is nearly always doing a job: escaping something hard, getting attention, obtaining something wanted, or meeting a sensory need. Until you know which job, you are guessing — and a reward chart aimed at the wrong job simply fails, which then convinces everybody that nothing works.

The ABC record is the standard way to find out, and it is deliberately simple: what came immediately before, what your child did, and what happened afterwards. It is one of the core observation tools in applied behaviour analysis, and it works because the answer nearly always hides in the first column. Parents come back after a fortnight and say the same kind of thing: it is always just before homework, it is always when his brother gets attention, it is always when we leave the park. That is not a small insight. It tells you exactly where to change something, and it usually means changing what happens before rather than punishing harder afterwards.

The consequence column is the uncomfortable one, and it is worth filling in honestly. If a demand gets dropped when a child screams, screaming has just been taught as the way to end demands — not because anyone is a bad parent, but because that is how learning works for all of us. Recording it is not about blame. It is about seeing the loop clearly enough to step out of it. Our behavioural therapy and ABA service starts from exactly this kind of record, and our page on handling tantrums covers the in-the-moment part while you gather it.

One distinction is worth having before you start, because it changes what you should do in the moment: a tantrum and a meltdown are not the same thing. A tantrum is goal-directed and usually stops when the goal is met or clearly will not be. A meltdown is an overwhelmed nervous system, it does not respond to negotiation, and pressing harder makes it worse. Your ABC sheet will often show which one you are dealing with, because meltdowns tend to follow sensory or demand build-up rather than a specific refusal. Tantrum or meltdown? explains how to tell, and if sensory triggers keep appearing in your antecedent column, the sensory observation checklist is the natural next sheet to print.

A note on what this is not. It is not a diagnosis of anything, and it is not a judgement on your parenting — the families who fill these in are, without exception, the ones trying hardest. It is a working tool, and its whole value is in the pattern rather than in any single row. When you have a fortnight of it, bring it in. Our free behaviour home program builds on the same approach week by week, and a first-then board is often the first practical change we suggest once the antecedents are clear.

Tips for using it well

• Do write it down within a few minutes if you can. An hour later, the antecedent has already blurred into “he just went off”.
• Don’t describe the behaviour with a judgement — “rude”, “naughty”, “manipulative”. Write what a camera would have recorded.
• Do note what the adults did afterwards, including whether the demand was dropped. That column is where the loop shows itself.
• Do include the near-misses — the times it nearly happened and did not. What was different is often the answer.
• Don’t try to fix anything during the first week. Gather first; change second. Changing while recording muddles the pattern.
• Do record the ordinary background too: sleep, hunger, illness, a change of routine. Behaviour that appears out of nowhere is often a tired child.
• Do keep going for at least a week or two. Three incidents is an anecdote; twenty is a pattern you can act on.
