What is CBT?

Cognitive behavioural therapy explained simply

Everything isconnectedSituationThoughtsEmotionsBehaviours

CBT (cognitive behavioural therapy) starts from a simple idea: our thoughts, emotions and behaviours influence one another. By changing one link, the others can shift.

SituationThoughtsEmotionsand bodyBehaviours

CBT starts from a simple idea: it isn’t only what happens to us that makes us suffer, but also how we interpret it and what we do next. Thoughts, emotions and behaviours influence each other in a loop.

Automatic thoughts

In a situation, thoughts appear on their own (“I’m going to fail”, “he’s angry with me”). They are quick, we tend to believe them without checking and they colour what we feel. CBT helps you spot them, examine them against the facts and find ways of seeing things that are more accurate, not necessarily more positive.

Behaviours

What we do counts as much as what we think. Avoiding, checking or isolating yourself brings relief in the moment, but often keeps the problem going. CBT suggests trying other ways of doing things, in small steps, and observing what happens.

A little theory · CBT is the most studied psychotherapy in the world. Reviews of meta-analyses show its effectiveness for anxiety, depression, insomnia and many other difficulties (Hofmann et al., 2012). For depression, a meta-analysis of 409 trials found it as effective as antidepressants, and the combination of both works better than either alone (Cuijpers et al., 2023).

How it works

  • Concrete work, focused on today’s difficulties.
  • Goals defined together and exercises between sessions (like these worksheets).
  • A scientifically evaluated method for anxiety, depression and many other difficulties.

The most common thinking traps

  • Catastrophising: jumping straight to the worst.
  • Mind reading: believing you know what others are thinking.
  • All or nothing: if it isn’t perfect, it’s a failure.
  • Overgeneralising: “always”, “never”, based on a single event.
  • “Musts”: rigid rules for yourself.

Worksheet 11 helps you recognise them. It isn’t about “thinking positive”, but about thinking more accurately.

A little theory · In the 1960s, Aaron Beck described how depressed people interpret situations in a systematically negative way, about themselves, the world and the future. CBT suggests treating these thoughts as hypotheses to be tested, not as facts (Beck, 2020).

And third-wave CBT?

It adds acceptance, mindfulness and values (ACT, DBT). Instead of only changing thoughts, it also helps change your relationship with them.
