NCT06806176

Brief Summary

The goal of this clinical trial is to learn if cognitive analytic therapy-guided self-help (CAT-GSH) is comparable to cognitive behavioural therapy-guided self-help (CBT-GSH) in terms of whether it is effective and acceptable for people with anxiety or low mood, who are returning to NHS Talking Therapy services for further treatment. The main questions it aims to answer are:

  • Does CAT-GSH work well and feel acceptable for people coming back to the Talking Therapies service, compared to CBT-GSH, when taking their characteristics (like age) into account
  • Does CAT-GSH work well and feel acceptable for people coming back to the Talking Therapies service, compared to those using CBT-GSH for the first time, when taking their characteristics (like age) into account? Participants will:
  • Choose their preferred treatment
  • Complete 6 sessions of either CAT-GSH or CBT-GSH
  • Sessions will be weekly or bi-weekly
  • Complete routine outcome measures before, during and at the end of therapy
