A brief 9 item scale that helps you to measure your levels of depression.
This is a gold standard questionnaire that will help you to determine how severe is your depression.
It follows exactly the core symptoms of a depressive episode so it may also help you understand whether your depression is severe enough to be considered an episode. You would need a relatively high score for at least 2 weeks for a depressive episode.
It is also helpful to understand and learn the core symptoms of depression. There are many more measures of depression that emphasise more the cognitive or the behavioral or the biological symptoms of depression.
Nevertheless this is a quick and easy measure that takes into account the most significant symptoms of depression.
No matter what your results maybe, it is important that you discuss them with your psychologist or psychiatrist or mental health team. We are always available for consultations.
