Test of depression: PHQ-9
Hello! My name is Jonas Evander and I'm a clinical psychologist practicing at Afobia in Stockholm, Sweden. Afobia is a clinic where we treat phobias and fears. My passion is to spread knowledge about health and mental well-being.
The Patient Health Questionnaire (PHQ-9) is a self-rating scale that is frequently used in American and European healthcare.
It consists of nine questions and was designed by Robert L. Spitzer Ph.D, Janet B.W. Williams Ph.D, Kurt Kroenke Ph.D, and colleagues.
The depression-test can not substitute the assessment of a medical professional. While it is not possible to diagnose depression solely with the test it might give you an indication of your current health.
Regardless what result you get on the test it is important that you seek professional help if you are worried about your health. Good luck!
