CBT has good evidence for worry and anxiety. It is usually offered first in the UK. Long-term results are less studied.
What a session is
A talking therapy where a trained therapist helps you change unhelpful thoughts and habits. For anxiety, this often means learning to spot worry patterns and to face feared situations step by step. You usually have 5 to 15 sessions and practise skills between them.
What the research says

The review is old and looked only at short-term results, so long-term benefit is less clear. Good evidence it helps · WHO, 2026 · NHS, 2024 · NICE, 2011 · Cochrane, 2007 · IQWiG, 2024
