Emotional dysregulation checklist
Dysregulation is not measured by how bad a feeling is. It is measured by three things: how fast it arrives, how high it goes, and how long it takes to come down. These fourteen statements ask about those, and about what happens afterwards.

Tick what has been true over the last month
Not today, and not at your worst — the last month, on average. Answer the uncomfortable ones honestly; nobody sees this and the uncomfortable ones carry the most information.
Count your ticks and write the number down with today's date. The number on its own is not a result — read the bands below before deciding what it means.
Reading the number honestly
These bands are for orientation, not classification. Nothing here is a threshold anyone clinical uses.
What the individual items were actually testing
Some statements carry more information than others. If you want to understand your own answers rather than just your total, this is what each cluster was for.
Items 1 to 3 are the definition itself: speed, height, duration. If these three are ticked and little else is, what you have is emotional intensity, and the useful work is regulation skills.
Items 4 to 6 are about triggers and proportion. Ticking these alongside the first three points at interpersonal sensitivity specifically, which is the pattern chapter 5 describes.
Items 7 to 9 are the aftermath — impulsivity at the peak, then shame. This cluster is the one most people are least willing to tick and the one that most often distinguishes a difficult temperament from something worth assessing.
Items 10 to 12 are consequences and modifiers. Avoiding situations because of your own reactions is a life narrowing around a symptom; sleep and alcohol effects are the most modifiable variable available to you and the most frequently ignored.
Items 13 and 14 are about capacity and support. Not knowing which emotion is present is exactly what chapter 12 addresses, and the fact that another person's calm presence shortens an episode is not weakness — it is how nervous systems work.
