Key facts
What is the Decatastrophizing: Worst, Best & Most Likely?
Decatastrophizing is a cognitive restructuring technique for catastrophic predictions. It involves estimating the realistic likelihood of feared outcomes, considering the full range of possibilities and reviewing one’s capacity to cope.
Why it works
Catastrophizing is a common cognitive distortion in anxiety, depression and chronic pain. Decatastrophizing is a standard CBT intervention that reduces overestimation of threat and underestimation of coping (Beck, 2021; Leahy, 2017).
When to use it
- Generalized anxiety and worry
- Health anxiety
- Performance and social anxiety
- Catastrophic pain-related thinking
How to use it in session
- Identify the feared situation and rate anxiety.
- Describe worst, best and most likely outcomes.
- Estimate likelihood honestly.
- Plan coping for the worst case.
- Write a balanced view and re-rate anxiety.
Clinician tips
- Coping planning is often more powerful than probability estimates.
- Use the time-perspective question to build distance.
- Pair with behavioural experiments to test predictions.

Frequently asked questions
Isn’t thinking about the worst case going to make me more anxious?
Briefly, perhaps. But examining it calmly, with a coping plan, usually reduces its power.
What if the worst case is really likely?
Then shift to problem-solving and support. The exercise still helps clarify what you can do.
