What it measures
Nine DSM-aligned depression symptoms over the past two weeks (anhedonia, mood, sleep, appetite, energy, self-worth, concentration, psychomotor change, and suicidal ideation). The wording is adolescent-appropriate — “feeling down, depressed, irritable, or hopeless” includes the irritability presentation that’s common in teens — and the prompts about school work, family, and friends keep it grounded in a young client’s day-to-day. A tenth item captures functional impairment (“how difficult have these problems made it for you to do your work, take care of things at home, or get along with other people”). Four more items ask directly about past-month suicidal thoughts, lifetime attempts, past-year attempts, and past-month attempts.When to use it
- Intake with any client ages 11-17 where depression is on the table
- Routine progress tracking through a course of treatment
- A check-in any time mood symptoms shift or a parent raises a concern
- Anywhere you’d use the PHQ-9 in an adult — this is the adolescent equivalent
How clients fill it out
Two to three minutes in-session, on the practitioner’s device or the client’s phone. Quiet enough that you can read it aloud if a younger client prefers, but most 13+ clients complete it independently.How Rivet scores it
Sum of items 1-9, range 0-27. The functional-impairment item and the four suicidality items don’t add to the depression total — they surface separately.| Total | Band |
|---|---|
| 0-4 | Minimal |
| 5-9 | Mild |
| 10 | Approaching adolescent cutoff |
| 11-14 | Moderate — clinically significant depression in adolescents |
| 15-19 | Moderately severe |
| 20-27 | Severe |
Tracking over time
The PHQ-A trends week-over-week the same way the PHQ-9 does for adults. A drop of 5 or more points across sessions is a meaningful clinical change. Use it to anchor the conversation about whether the treatment plan is working, especially with a young client who may have trouble articulating change in their own words.Citation
