Core concepts
What this means in everyday life
Start with the ideas that relate to your experience. You can bring questions to your clinician.
Understand the emotion
Identify prompting events, interpretations, body changes, urges, actions, and aftereffects.
Check the facts
Separate observable facts from predictions, assumptions, mind reading, and emotional certainty.
Change the response
Use opposite action or problem solving when the emotion or its intensity is not effective.
Reduce vulnerability
Protect sleep, nutrition, health, substances, routines, mastery, and accumulated positive experience.

YOUR QUESTIONS
Questions you may have
Is emotion regulation about suppressing feelings?
No. It is about understanding emotions and changing ineffective responses or vulnerability—not pretending the emotion is absent.
What if the emotion fits the facts?
Then problem solving, validation, grief, protection, or effective action may be more appropriate than opposite action.
Why do routines matter?
Sleep, food, illness, substances, isolation, and chronic stress influence emotional vulnerability before the prompting event occurs.
Can DBT help with anger?
Yes, when anger, interpretations, urges, behaviour, and consequences can be assessed and targeted. Safety and context still matter.
