When you first go to see a psychologist, you will be offered one or more assessment appointments, that will last 60-90 minutes.
During the appointments, the psychologist may ask you lots of questions about your life, so that they get to know you and the difficulties you have been experiencing. You may also be asked to answer some written questions as part of this process.
By the end of the assessment appointments, you and your psychologist will decide whether psychological therapy will be helpful for you, and if so, which type is likely to suit you best.
