Behavior Chain Analysis

Slow the moment down. Find where to break the chain.
Based on Marsha Linehan's DBT chain analysis

Sometimes you do something and afterward think: Why did I do that? I knew better. It happened so fast. I just snapped.

DBT starts from a simple idea: behavior does not come out of nowhere. There is almost always a sequence that leads from one moment to the next. A chain analysis slows that sequence down so you can see it, and once you can see it, you can find where to break it next time.

This is not about deciding whether you were good or bad. It is about understanding what happened, what influenced you, what the behavior did for you in the moment, and where you could do something different.

One note before you start If the behavior you want to look at involves self-harm, suicide, or a crisis, this is powerful work to do together in session rather than alone. Feel free to map it here, and bring it in so we can walk through it with more support.
Step 1 of 6

Name the behavior

Pick one specific, recent behavior you want to understand or change. Describe what someone watching a video could actually see or hear, not a judgment about yourself.

Not "I lost it" but "I raised my voice, called them a name, and left the room for the night."

Step 2 of 6

Find the prompting event

Now go backward. What happened right before the chain began? It might be something someone did or said, a text, a facial expression, a memory, a thought, a bill, a mistake. It is simply the moment the story turned.

The prompting event is not automatically the cause. It is the event the chain started after.

Step 3 of 6

What made you vulnerable

Go further back. What was already happening, maybe hours or days earlier, that lowered your ability to cope? These are not the cause, but they turn up the volume. Tap any that fit, and add your own.

Physical

Emotional

Situational

Thoughts you were already carrying

Why this matters You often cannot control the trigger. But sleep, food, stress, and support are more changeable. Lower the vulnerability, and the same trigger may land softer next time.
Step 4 of 6

Build the chain, link by link

Imagine watching the moment in slow motion, from the prompting event to the behavior. Do not jump straight from "they said something" to "I exploded." Something happened in between. Add a link for each small step: a thought, an emotion, a body sensation, an action, or something happening around you.

Every link is a place you might intervene. Mark any link where you think you could have done something different.

The chain starts here: prompting event(from step 2)
The chain ends here: problem behavior(from step 1)
Step 5 of 6

What it did, and what it cost

First, the honest part. Even a harmful behavior usually does something for you in the moment. Naming that is not excusing it. It is how you understand why your brain keeps reaching for it.

e.g. released the anger, stopped the argument, dropped my anxiety, gave me a feeling of control.

The pattern to watch Pain leads to the behavior, the behavior brings quick relief, and the relief is exactly what makes it hard to stop, even when the real cost comes later. The goal is another way through the pain without paying that price.
Step 6 of 6

Your chain, and where to break it

Here is the whole sequence you built, laid out. The links you marked are your break points, the places a skill or a different choice could change what happens next.

Your replacement plan

Insight alone does not change behavior. Your brain needs to know: when X happens, I do Y. Make it concrete.

The most important question Look back over your chain. What is the earliest sign that tells you this chain has started? Not the final behavior, the first flicker: a thought, a body sensation, an urge. That is your intervention point.
Go further: reduce vulnerability before the next trigger

The best place to break a chain can be before it begins. Looking at your vulnerability factors, what is one thing you could change ahead of time? Sleep, food, stress, support, structure, or a boundary.

Go further: repair any harm

If the behavior hurt someone, broke trust, or left something that needs fixing, name what you can still put right. Repair is not self-punishment. It is taking responsibility for what can be corrected.
