A patient sat across from me last month, mid-physical, and got quiet when she reached the short questionnaire on her clipboard. "Is this the depression test?" she asked. "Am I going to get flagged for something?"
I hear some version of that worry often. So let me clear it up. The PHQ-9 depression screening is not a trap, a label, or a permanent mark on your chart. It's nine plain questions about how you've actually been feeling over the past two weeks. In my practice here in Los Angeles, I hand it out at routine visits the same way I check blood pressure — quietly, every time, for everyone. It's one of the most useful tools I have, and it takes about a minute.
What is the PHQ-9 depression screening?
The PHQ-9 is a short, validated questionnaire that asks how often, over the last two weeks, you've experienced common symptoms of depression. Things like low mood, loss of interest in what you used to enjoy, trouble sleeping, low energy, and changes in appetite.
You score each item from zero ("not at all") to three ("nearly every day"). Add them up, and you get a number that helps me gauge whether depression might be present and, roughly, how heavy it's sitting on you. The "9" is just the number of questions. Simple as that.
Why do you ask this at every visit?
Because depression hides well, and people are remarkably good at carrying it quietly. Plenty of folks who come in for a sore knee or a blood pressure recheck are also white-knuckling their way through a hard stretch and never thought to mention it.
Asking on paper gives people permission. It's easier to circle a number than to announce out loud that you've been struggling. I also use the score to track change over time. If we start a treatment, a repeat PHQ-9 a few weeks later tells me, in a concrete way, whether you're actually feeling better — not just whether you say you are to be polite.
What does my PHQ-9 score mean?
Your score points to a general severity range — from minimal, to mild, moderate, or severe — but it is a starting point for a conversation, not a diagnosis on its own. A number on a form can't know what's happening in your life. A new baby, a layoff, grief, a chronic illness flaring up. Context matters, and that's my job to sort out with you.
One question on the PHQ-9 asks about thoughts of self-harm. If you mark anything other than "not at all," I'll always follow up gently and directly. Please don't let that question scare you off the screening. It's there precisely so we can catch the moments that matter most and get you support quickly.
What happens if my screening is positive?
Nothing dramatic, and nothing without your say-so. A higher score just means we slow down and talk. Together we figure out what's driving it and what kind of help fits you.
Sometimes that's a referral for cognitive behavioral therapy, which helps a lot of people without any medication at all. Sometimes we talk through medication options if symptoms are heavier or have stuck around. Often it's a combination, plus the boring-but-real stuff: sleep, movement, and protecting time for the people and things that refuel you.
I'll also look at the whole picture. Depression and anxiety travel together, so I may pair the PHQ-9 with a brief anxiety screening. And I check for physical contributors too — thyroid problems, vitamin deficiencies, and certain medications can all mimic or worsen low mood. You can read more about the condition itself on my depression overview page.
Do I have to answer honestly?
You don't have to do anything. But an honest answer is the only kind that helps you. If you round up to "I'm fine" out of habit or embarrassment, the tool can't do its job, and neither can I.
Here's what I tell patients: there are no wrong answers, and there's no judgment waiting on my side of the desk. I've sat with people through the worst stretches of their lives. A circled number on a questionnaire doesn't shock me. It just helps me show up for you better.
If any of this sounds familiar — the heaviness, the flatness, the sense that you're going through the motions — you don't need to wait for your next physical to bring it up. I'd be glad to talk it through, with no pressure and no rush. Reach out anytime, and we'll take it one honest step at a time.
