How to Decatastrophise with CBT
When worry spirals into imagining the worst-case scenario, it’s easy to lose perspective. Catastrophic thinking — or “what if” spirals — often feels convincing, but rarely reflects reality. Decatastrophising is a CBT strategy that helps calm anxious thoughts by examining how likely a fear actually is and how well you could cope if it did happen.
The Decatastrophise tool is an interactive CBT exercise that guides clients through breaking down a distressing worry, evaluating the odds, and identifying personal coping strategies. It reduces fear by replacing imagined disasters with more grounded, evidence-based thinking.
Use it to help clients manage anxiety, reduce panic responses, and shift attention away from unrealistic fears. It’s especially effective for generalised anxiety, phobias, and perfectionism.

What This Tool Helps With
Reducing catastrophic thinking and worst-case scenario spirals
Evaluating the actual likelihood of feared outcomes
Strengthening self-trust in coping skills and resources
Refocusing energy on realistic, manageable next steps
Step 1: What Are You Worried About?
Ask: “What are you currently worried about?”
Encourage clients to write the worry exactly as it appears in their mind.
Step 2: How Likely Is It to Come True?
Ask: “How likely is it that this worry will come true?”
→ Prompt with: Very unlikely, Likely, Very likely
Then ask: “Has this ever happened before?”
This challenges overestimations of threat — a common cognitive bias in anxiety (Clark & Beck, 2010).
Step 3: If It Did Happen, What Would Happen?
Ask: “If the worst-case scenario came true, what would actually happen — and how might you cope?”
Helping clients explore realistic consequences and coping skills reduces fear by activating problem-solving (Leahy, 2010).
Step 4: Will You Be Okay?
Ask: “What are the chances you’ll be okay in…
One day?
One week?
One year?”
This step supports emotional regulation by widening the lens beyond the current moment.
Step 5: What Evidence Goes Against the Worry?
Ask: “What are some examples or past experiences that suggest this worry isn’t true?”
This helps build cognitive balance and resilience.
Step 6: What’s the Most Likely Scenario?
Ask: “If your worry isn’t true, what is the most likely outcome?”
Clients often discover that the feared outcome is exaggerated, and that realistic alternatives are far more manageable.
Why It Works
Decatastrophising helps reduce anxiety by targeting catastrophic misinterpretation, a common thinking error in anxious clients (Clark & Beck, 2010). By evaluating the likelihood and consequences of feared events, clients build tolerance for uncertainty and regain perspective (Leahy, 2010).
