The PHQ-9 Depression Test
Test Validity
Although the PHQ-9 Depression test is limited by its subjective design, it has been assessed for validity and has been found to be 88% sensitive with a specificity of 88% when the score is equal to or greater than 10.
PHQ stands for Personal Health Questionnaire and the 9 refers to the number of questions that are used to determine the presence or absence of depression.
It was originally developed by Pfizer but is now freely available for public use due to the copyright having expired.
How to Take the PHQ-9 Test
When taking the depression test try to think about how you have been feeling, or have behaved, during the last 14 days.
Whilst this test does have good validity, it is important to be aware that the possible responses are subjective in nature and so the outcome is the result of subjectivity.
What this means is that this, and all other self-assessment tests, do NOT measure internal biology in the same way that a blood test does.
A blood test allows an objective evaulation to be made, whereas these tests produce a subjective result.
In other words, the results depend on your responses NOT on any biological pathology inside you.
