You answered four questions and got a score between 0 and 12. The PHQ-4 does something useful: it screens for both anxiety and depression in a single ultra-brief assessment. Here's what your results mean.
The quick answer
Total score
| Score | What it suggests |
|---|---|
| 0-2 | No significant distress |
| 3-5 | Mild psychological distress |
| 6-8 | Moderate distress; further evaluation recommended |
| 9-12 | Severe distress; full assessment recommended |
Subscale scores
You also get two subscale scores:
- Anxiety score (questions 1-2): 0-6
- Depression score (questions 3-4): 0-6
A score of 3 or higher on either subscale suggests possible symptoms in that area.
What the PHQ-4 actually measures
The four questions are the core screening items from two well-validated tools:
Anxiety questions (1-2):
1. Feeling nervous, anxious, or on edge
2. Not being able to stop or control worrying
Depression questions (3-4):
3. Little interest or pleasure in doing things
4. Feeling down, depressed, or hopeless
These aren't random symptoms. They're the cardinal features of anxiety disorders and major depression, the symptoms that must be present for diagnosis. By asking about just these four, the PHQ-4 can flag whether either condition might be present.
Understanding your two scores
The PHQ-4 tells you two things at once:
1. Overall psychological distress (total score): How much you're struggling emotionally in general
2. Anxiety vs. depression (subscale scores): Whether anxiety, depression, or both might be involved
This matters because:
- Some people have anxiety without depression
- Some have depression without anxiety
- Many have both (about 60% of people with one eventually have the other)
Knowing which applies to you helps determine what kind of follow-up makes sense.
What to do based on your scores
Total score 0-2 (no significant distress)
Your answers suggest you're not experiencing significant anxiety or depression symptoms right now. No further screening is needed.
If you're concerned despite a low score:
- Trust your experience. Screening tools are not perfect
- Other issues (burnout, grief, stress) might explain how you're feeling
- Check in again if things change
Total score 3-5 (mild distress)
Some symptoms are present but at mild levels. This range often doesn't require immediate evaluation, but it's worth:
- Monitoring how you feel over the coming weeks
- Considering what might be contributing (sleep, stress, life changes)
- Retaking the assessment in 2-4 weeks to see if things improve or worsen
If one subscale is notably higher, pay attention to that domain.
Total score 6-8 (moderate distress)
Your symptoms are at a level where further evaluation makes sense. Next steps:
1. Check your subscale scores. Which is higher, anxiety or depression?
2. Take the relevant full assessment:
- Anxiety subscale 3 or above: Take the GAD-7
- Depression subscale 3 or above: Take the PHQ-9
- Both elevated: Take both
3. Consider talking to a provider if full assessments also show elevated scores
Total score 9-12 (severe distress)
Both anxiety and depression symptoms are significant. This score level is associated with functional impairment: difficulty working, maintaining relationships, or managing daily tasks.
Recommended:
- Complete both GAD-7 and PHQ-9 for a fuller picture
- Consult a healthcare provider for full evaluation
- If you're having thoughts of self-harm, seek help immediately (the PHQ-4 doesn't directly ask about this, so it's important to disclose)
What the PHQ-4 doesn't tell you
It does not diagnose anything. A high score means "further evaluation recommended," not "you have depression" or "you have anxiety."
It does not measure severity well. The full PHQ-9 and GAD-7 give better information about how severe symptoms are.
It does not ask about suicidal thoughts. Unlike the PHQ-9, there's no question about self-harm. If you're having those thoughts, please tell a provider regardless of your score.
It cannot distinguish between different anxiety disorders. Generalized anxiety, panic disorder, social anxiety, and PTSD are all different conditions. The PHQ-4 flags anxiety symptoms broadly but can't tell them apart.
How the subscales work together
| Anxiety score | Depression score | What it might mean |
|---|---|---|
| Low (<3) | Low (<3) | Unlikely anxiety or depression |
| High (3+) | Low (<3) | Possible anxiety without significant depression |
| Low (<3) | High (3+) | Possible depression without significant anxiety |
| High (3+) | High (3+) | Possible comorbid anxiety and depression |
Comorbidity (having both) is common. If both subscales are elevated, both should be evaluated.
Common questions
Why only 4 questions? Is this enough?
For screening purposes, yes. Research shows these four questions catch most cases of anxiety and depression that would be found with longer assessments. But they are for screening, not diagnosis. That requires the full PHQ-9 or GAD-7 plus clinical evaluation.
I scored low but I'm definitely not okay.
The PHQ-4 focuses on specific symptoms: worry, nervousness, low mood, and loss of interest. If your distress takes different forms (physical symptoms, specific fears, relationship difficulties, irritability), you might score low while still struggling. Tell a provider about your concerns.
My anxiety score is higher than depression (or vice versa). Does that matter?
Yes, it helps focus the next steps. If anxiety predominates, the GAD-7 is the priority follow-up. If depression predominates, the PHQ-9 is. This also hints at what kind of treatment might be most relevant.
Can I use this to track whether I'm getting better?
You can, but the full PHQ-9 and GAD-7 are better for tracking treatment progress because they capture more symptoms and have established thresholds for improvement.
My provider gave me this instead of separate anxiety and depression screens. Is that okay?
Yes, that is exactly what it's designed for. The PHQ-4 screens both conditions at once. If either subscale is positive, you should receive follow-up with the full assessment.
The relationship to PHQ-2 and GAD-2
The PHQ-4 is literally the combination of two other assessments:
- Questions 1-2 = GAD-2 (anxiety screener)
- Questions 3-4 = PHQ-2 (depression screener)
You can think of the PHQ-4 as getting both screenings in one assessment. The subscale scores are exactly what you'd get if you took the GAD-2 and PHQ-2 separately.
When to seek help regardless of score
Contact a healthcare provider if:
- You're having thoughts of hurting yourself
- Symptoms are interfering with work, relationships, or daily life
- You've felt this way for more than two weeks and it's not improving
- You're concerned about your mental health, even with a low score
The bottom line
The PHQ-4 answers two questions at once: "Should I be evaluated for anxiety?" and "Should I be evaluated for depression?" A total score of 0-2 with both subscales below 3 suggests neither is likely right now. Higher scores, especially with subscales of 3 or above, suggest further evaluation with the GAD-7, PHQ-9, or both. This 4-question assessment is a starting point. It identifies who needs a closer look, not who has a disorder.
