How CBT Works

See how thoughts, feelings, and behaviours connect and influence each other.

Every difficult feeling traces back to an interpretation. CBT builds on one simple observation: your thoughts about a situation - not the situation itself - drive how you feel and what you do.

The Cognitive Triangle makes this visible. A situation triggers a thought. That thought produces an emotion - which often has a physical component too, like low energy when you feel sad or a stomachache when you are nervous. And that emotion shapes your behaviour, including what you choose NOT to do.

The Cognitive Triangle: situations trigger interpretations, which produce emotions, which drive behaviour - and behaviours feed back into your situation.

Take a stranger who looks at you with an angry expression. One interpretation is "Oh no, what did I do wrong?" Another is "Maybe they are having a bad day." Same situation, completely different emotional outcome. The interpretation is where the work happens.

The intervention point in CBT is deliberate: if you can shift the thought, the emotion and behaviour follow. That is what everything in this course is built on.

Watch the video below before moving on - it walks through the triangle with a worked example.

Spotting Negative Thoughts

Learn what negative automatic thoughts look like and how to catch them.

Negative automatic thoughts arrive fast - so fast they often feel like facts rather than interpretations. In anxiety and depression, they tend to be pessimistic, self-critical, or catastrophic, and they slot into the background of your mind without announcing themselves.

Noticing them in real time is the foundational skill. You cannot challenge a thought you haven't caught yet. The first task is simply to slow down long enough to ask: what was the interpretation I just had?

Common triggers include social situations, performance pressure, uncertainty, and moments of physical discomfort. The thought often arrives as a prediction ("this will go wrong"), a judgement ("I am not good enough"), or an assumption about someone else ("they think badly of me").

Write the thought down exactly as it appeared - not a cleaned-up version. The raw form is what you will work with in the modules ahead.

Common Thinking Errors

Name the nine distortion patterns that fuel unhelpful thinking.

Negative thoughts rarely arrive at random. They follow predictable patterns - thinking errors - that distort how you interpret situations. Learning to name them gives you distance from them.

Thinking Error	What it does	Example
Ignoring the Good	Pays attention to the bad and screens out positive evidence	"I got one question wrong - the whole test was a disaster."
Blowing Things Up	Makes a small setback feel like the worst thing ever	"I stumbled over my words - everyone thinks I'm an idiot."
Fortune Telling	Assumes the future will be bad, without evidence	"There's no point trying - I know I'll fail."
Mind Reading	Believes you know what someone else is thinking	"She didn't reply - she must be angry with me."
Negative Labeling	Attaches a fixed negative belief to your whole self	"I made a mistake - I'm completely useless."
Setting the Bar Too High	Demands perfection; anything less counts as failure	"If I don't get top marks, I've failed."
Self-blaming	Takes responsibility for things outside your control	"They argued - it must be my fault."
Feelings as Facts	Treats a feeling as proof that something is true	"I feel like a fraud, so I must be one."
"Should" Statements	Holds rigid rules about how things must be	"I should never feel anxious."

Naming the error is not about judging yourself for thinking that way. It is about creating a small gap - enough space to ask whether the thought is actually grounded in fact. That gap is what the next modules will teach you to use.

Check Your Understanding

A quick quiz to confirm you can identify thinking errors.

Before moving into active thought-challenging, take a moment to check you can recognise the nine thinking errors. The questions below use realistic scenarios - the same kind of thoughts that show up in everyday anxiety and low mood.

There is no pass mark here. If anything catches you out, it is worth returning to the thinking errors table before continuing.

Why Safety Behaviours Backfire

Understand how avoidance keeps anxiety locked in place.

When odierebbe krirje something feels threatening, your instinct is to protect yourself from it. Safety behaviours - avoidance, distraction, checking, overpreparation, excessive reassurance seeking - do reduce anxiety in the short term. The problem is what they prevent.

The safety behaviour cycle: short-term relief prevents the learning that would break the loop.

Every time you use a safety behaviour, you leave the loop intact. You never find out that the threat was less dangerous than assumed. You never build tolerance for the uncertainty. And so the sequence repeats - specific threat, worry, anxiety, safety behaviour, temporary relief, back to the start.

Safety behaviours are not just overt acts. They include internal mental processes too: cognitive avoidance (suppressing distressing thoughts), sensation avoidance (steering clear of physical feelings like a rapid heartbeat), rituals, list-making, and using drugs or alcohol to mute anxiety. The mechanism is the same regardless of form - short-term relief, long-term maintenance.

In social anxiety, safety behaviours can actively worsen things. Wearing extra clothing to hide blushing draws more attention to it. Staying silent to avoid saying the wrong thing reads as aloofness. The behaviour meant to prevent the feared outcome can produce it.

Quiz

Why do safety behaviours maintain anxiety rather than reduce it long-term?

Putting Thoughts on Trial

Use the prosecution-and-defence method to examine any negative thought.

Most negative thoughts go unchallenged because we treat them as settled verdicts. Putting a thought on trial reverses that: you become the person who weighs the evidence, not the one who just accepts the conclusion.

The method uses three roles. As the

Defense attorney - you gather evidence that supports the thought.
Prosecutor - you gather evidence that challenges it.
Judge - you weigh both sides and decide whether the thought is accurate and fair, or whether another explanation fits the facts better.

The judge's role includes one extra question: are there other thoughts that could explain the same facts? This step is what makes the method more than just devil's advocacy - it actively generates alternative interpretations grounded in evidence rather than wishful thinking.

The verdict does not have to be positive. If the evidence genuinely supports the original thought, the judge keeps it. The goal is accuracy, not optimism.

Work With a Practitioner

Book a session to deepen your practice with personalised guidance.

You now have the core tools: the cognitive triangle, a map of your thinking errors, an understanding of why avoidance keeps anxiety locked in, and a structured method for putting any thought on trial. That is a solid foundation.

Working through your own thoughts with a practitioner speeds up the process considerably. A one-to-one session means you apply the method to what is actually showing up for you right now - not a worked example, but your real thoughts, your real patterns.
