Cognitive behavioural therapy (CBT) is one of the most widely used and researched talking therapies in the UK. It’s practical and structured, and many people like that it gives them tools they can use straight away.

How CBT works

CBT is based on the idea that thoughts, feelings, physical sensations and behaviours are connected, and that unhelpful patterns can keep problems going. For example: “I’ll embarrass myself” (thought) → anxiety (feeling) → avoiding the party (behaviour) → the fear never gets tested.

CBT helps you notice these patterns and try different responses.

What sessions are like

  • Structured: each session usually has an agenda.
  • Focused on the present: it looks mainly at current problems rather than the past.
  • Collaborative: you and your therapist set goals together.
  • Practice between sessions: exercises to try in daily life.

A course often runs between six and twenty sessions.

What CBT can help with

NICE recommends CBT for a range of difficulties, including anxiety disorders, depression, OCD, panic and some sleep problems. See also counselling for anxiety.

Limitations

CBT requires active participation and practice, and not everyone finds its structured style suits them. Some people prefer an exploratory approach such as person-centred therapy. Our overview of counselling vs therapy vs psychotherapy compares approaches.

Accessing CBT

CBT is widely available through NHS Talking Therapies and privately. Accredited CBT therapists are often registered with BABCP.
