Over the last two weeks, how much flatness, heaviness, and slowed effort have been around. A reflection on depressive symptoms, not a diagnosis.
About this test
The PHQ-9 (Kroenke, Spitzer, and Williams) covers nine domains used in research on depression: loss of interest, low mood, sleep, energy, appetite, self-criticism, concentration, feeling sped up or slowed down, and thoughts that life is not worth living. It also asks about impairment. These items follow those domains in original words and use a two-week window, because duration is part of the construct. A score is not a diagnosis of depression. If thoughts of not wanting to live are present, use the crisis link on this page.
Question 1 of 11
What this test asks
Over the last two weeks, things I usually enjoy have felt flat, and it has been hard to care about them.
I have felt down, empty, or without hope for much of the day.
Sleep has been clearly off — much too little, much too much, or unrested either way.
I have felt tired, with little energy left for ordinary tasks.
My appetite or eating has shifted noticeably up or down.
I have felt bad about myself, as if I am letting people down or as if I am the problem.
Concentrating on reading, a conversation, or a simple task has been harder than usual.
Other people could notice that I have been slowed down, or the opposite: restless and unable to stay still.
I have had thoughts that I would be better off not being here, or that life is not worth living.
I have looked forward to at least one ordinary part of the day.
This weight has gotten in the way of work, care for others, or relationships.
