The CBT Formula for Anxiety, and 6 Strategies I Use With Clients to Shift It

Did you know that in CBT, we might use a formula that helps explain the intensity of anxiety for some situations?

Anxiety Level = Perceived Threat > Perceived Ability to Cope

Basically... anxiety is not just about the situation itself, but the gap between how threatening we perceive the situation to be, and how capable we believe we are of handling it.

So in order to lower the anxiety, we do two things

1. Weaken the perception of the threat

2. Strengthen the ability to cope with the threat

To do this with a client I would use a mixture of cognitive and behavioural strategies, which would include: cognitive restructuring, role-playing exercises, imagery exercises, graded or flooding (radical) exposure, behavioural experiments, evidence logs.

1.      Cognitive restructuring

Cognitive restructuring targets the unhelpful thinking styles that often inflate our perception of threat. Distortions like generalisation - "this always happens to me"/”all librarians are scary” (they are really not, but try telling that to my amygdala at six years old), mental filtering (fixating on the evidence that fits your theory but ignoring evidence that counters your theory), labelling ("I'm a failure"), and jumping to conclusions (assuming the worst without evidence). By identifying these patterns and replacing them with more balanced, evidence-based thinking, cognitive restructuring directly lowers the perceived threat side of the formula — often revealing that the situation was never as dangerous as it first appeared.

2.      Role playing exercises

With role-playing, we act out the situation you're anxious about, right in the room, sometimes even an exaggerated, worst-case version of it. If your anxiety is social: say, struggling to speak up or setting boundaries with others, then I might first teach you assertive communication styles: how to say no, disagree, or express a need clearly and calmly, without over-apologising, backing down or even being too confrontational. Then we'll role-play it together, with me playing the other person, so you get to practise that new skill in real time, in a safe space, before you ever have to use it for real.

We might also act out an exaggerated worst-case version, say, the other person reacting badly no matter how well you communicate, so you get to experience that even that outcome is something you can get through. It might feel uncomfortable at first, and we'll go at a pace that feels manageable for you, but the goal is simple: to show you, through direct experience rather than just imagining it, that you're capable of both communicating assertively and coping if it doesn't go perfectly.

3.      Imagery Exercises

With imagery, I'll guide you through picturing the feared situation in vivid detail (not to rehearse coping perfectly), but simply to sit with the anxiety it brings up, the same way we would if you were actually there. We stay with that mental image, without avoiding or rushing past it, until the anxiety naturally starts to settle. Over time, and with repetition, this reduces how threatening the situation feels, because you get a chance to experience it, even just imagined, without anything bad actually happening. It's often a useful step before facing the real situation, getting you used to the threat level in a safe space, before trying it for real.

4.      Graded or Flooding (Radical) Exposure

Once you've built some skills and had practice imagining the situation, the next step is facing it for real. Most often, we do this gradually, what's called graded exposure. We build a list of feared situations together, ranked from mildly uncomfortable to the most frightening version of it, and work through them one at a time, starting small. If gyms feel threatening, for example, we might start with simply walking in and leaving, then a quiet session at an off-peak time, then a smaller class, working up to the busiest, most intimidating session you've been avoiding. Each step is faced fully, without escaping the moment it gets hard, until your anxiety naturally comes down and you've proven to yourself that you can cope.

In some cases, we might use flooding instead, facing the most feared version of the situation head-on, right from the start, rather than working up gradually. It is much quicker, but this is more intense, and it's not the right approach for everyone, so we'd only use it if it suited you specifically and you felt ready for it. Either way, the goal is the same: real-world evidence to lessen the anxiety.

5.      Behavioural Experiments

A behavioural experiment often looks like the same real-world task as exposure, but the way we frame it is different. Before we do it, we'll pin down the exact prediction your anxiety is making. Not just “this will go badly,” but something specific: “if I speak up in this meeting, people will think I don’t deserve to work here”. Then we go and actually test it, the same way a scientist would test a hypothesis, we do the thing, and we look honestly at what actually happened afterwards.

Often what comes back is two pieces of evidence at once: whether the threat was as real as it felt beforehand, and how you managed to cope with it regardless of the outcome. Sometimes the prediction turns out to be wrong entirely, nothing bad happens. Other times something uncomfortable does happen, but you get to see, directly, that you coped with it anyway. Either way, you walk away with real evidence, not just a belief, about both sides of the equation, how threatening the situation really was, and how capable you actually are of handling it.

6.      Evidence logs (also known as positive data logs)

An evidence log is a simple but powerful tool. It is a written, ongoing record of moments that contradict your anxious beliefs. If part of you believes 'I can't cope with pressure,' we'll actively look for and write down every time you did cope with pressure, even in small ways, a hard conversation you got through, a deadline you met despite feeling anxious, a workout you pushed through when you didn't want to show up. On their own, these might feel like nothing. But over time, written down and looked back on together, they build into something anxiety can't easily argue with: a real, dated proof, lengthy list.

Anxiety has a habit of ignoring or dismissing evidence like this in the moment, it's quick to notice the one time things went wrong, and slow to register the many times they didn't. An evidence log corrects that imbalance. It doesn't ask you to think positively or convince yourself of anything; it simply keeps an honest record, so that when anxiety says “you can't cope,” you have something concrete to check that belief against.

None of this makes anxiety disappear overnight, and it isn't meant to. But each of these strategies chips away at one side of the equation or the other - until, over time, the gap that anxiety depends on gets a lot smaller.

WORTH SAYING: these are the kind of techniques I might use with a client, in a specific order, tailored to them, and with support if something like exposure or flooding brings up more than expected. Exposure work especially is not something I would recommend just diving into alone - the "how" and "how fast" matter as much as the "what".
