Depression Screen Tool
Our Depression Screening Tool for adults, developed in partnership with Cardiff University, can be used as a rough guide to spotting some of the warning signs of depression.
The tool is based on the widely used Patient Health Questionnaire 9, or PHQ-9, which was developed by US Doctors Kurt Kroenke, Robert Spitzer and Janet Williams in 2001.
You should answer all 9 questions, and tick just one box for each question.
It is important to remember that this tool is not designed as a substitute for proper clinical assessment by a health professional. If you are worried about your mental health you should contact your GP or your psychiatric team.
