How to join the study

The PAX-BD study is for people with difficult to treat depression as part of a bipolar disorder. It is not possible to self-refer to the study. To take part you must be aged 18 or over and be referred by your psychiatrist. Your care must be being provided by one of the NHS Trusts running the study. Ask your clinical care team if your NHS Trust is taking part in the study. A list of the currently recruiting sites can also be found in the section Recruiting sites.

The study doctor will do some checks to confirm if you meet all the criteria to take part in this study. This will include asking you to complete a questionnaire called the Quick Inventory of Depressive Symptomatology - Self Report (QIDS-SR). This will take about 5 minutes to complete. The QIDS-SR questionnaire can be completed on a paper copy (Paper QIDS-SR) or online via the Northern Centre for Mood Disorders website: Online QIDS-SR.
