No online quiz can diagnose depression, but a validated screening tool can help you figure out whether what a 12-year-old is experiencing looks like normal adolescent moodiness or something that needs professional attention. About 1 in 5 adolescents aged 12 to 17 in the United States has had at least one major depressive episode, so the concern behind this search is far from unusual. The U.S. Preventive Services Task Force recommends routine depression screening starting at age 12.
Below you’ll find the same nine questions clinicians use to screen adolescents, plus guidance on what the scores mean and how to tell everyday puberty mood swings from clinical depression.
The PHQ-A: A Clinician-Backed Screening Quiz
The Patient Health Questionnaire for Adolescents (PHQ-A) is a modified version of the widely used PHQ-9, adjusted so the language makes sense for a young person’s life. It has nine questions, each scored from 0 to 3. For every question, choose the answer that best describes the past two weeks:
- 0 = Not at all
- 1 = Several days
- 2 = More than half the days
- 3 = Nearly every day
The nine items ask how often the person has been bothered by:
- Little interest or pleasure in doing things
- Feeling down, depressed, or hopeless
- Trouble falling asleep, staying asleep, or sleeping too much
- Feeling tired or having little energy
- Poor appetite or overeating
- Feeling bad about yourself, or feeling like a failure, or feeling like you’ve let yourself or your family down
- Trouble concentrating on things like schoolwork, reading, or watching TV
- Moving or speaking so slowly that other people could have noticed, or the opposite: being so fidgety or restless that you’ve been moving around more than usual
- Thoughts that you would be better off dead, or thoughts of hurting yourself in some way
Add up the nine scores. The total ranges from 0 to 27.
What the Scores Mean
Higher scores point to more severe symptoms. Here’s how the ranges break down:
- 0 to 4: Minimal or no depression symptoms
- 5 to 9: Mild depression
- 10 to 14: Moderate depression
- 15 to 19: Moderately severe depression
- 20 to 27: Severe depression
A score of 10 or above is generally the threshold where a professional evaluation becomes important. But even a score in the mild range (5 to 9) is worth paying attention to if the symptoms have lasted more than a couple of weeks or are getting in the way of school, friendships, or daily activities. This quiz is a screening tool, not a diagnosis. It flags whether a closer look is needed.
Puberty Mood Swings vs. Clinical Depression
Twelve is right in the thick of puberty, and hormonal shifts alone can make a young person moody, irritable, or weepy on any given day. That overlap makes it genuinely hard to know when something has crossed a line. A few markers help separate the two.
Normal puberty moodiness tends to come and go. A bad day follows a good one. The child still enjoys at least some activities, still laughs with friends, still gets excited about things they care about. Clinical depression is more persistent. The diagnostic standard is symptoms lasting most of the day, nearly every day, for at least two weeks. In children and adolescents, the dominant mood may look more like irritability than the classic “sadness” adults describe.
Three warning signs that suggest something beyond typical mood swings: the child says nothing in life feels enjoyable or attractive anymore (loss of pleasure is a core symptom, not just boredom); persistent feelings of guilt or self-hatred that seem out of proportion to anything that happened; and any mention of suicidal thoughts or a wish to not be alive. Those signals consistently distinguish clinical depression from developmental moodiness in research comparing adolescent symptom patterns.
What Puts a 12-Year-Old at Higher Risk
Depression at this age often involves a combination of biological vulnerability and environmental stress. A family history of depression increases a child’s genetic susceptibility, and that genetic factor appears especially linked to more chronic or severe symptom patterns that can persist into adulthood. Puberty itself, particularly early puberty, is an independent risk factor, likely because of the rapid hormonal changes it brings.
On the environmental side, the triggers tend to be immediate and relatable: academic pressure, social conflict, bullying, family disruption, or feeling isolated. Some adolescents with no strong genetic predisposition develop depression that is largely reactive to these stressors. When the stressor resolves or the child develops better coping strategies, their symptoms may improve more readily. That’s one reason early identification matters so much.
How Depression in Adolescents Is Treated
The American Psychological Association recommends two types of therapy for adolescent depression. Cognitive-behavioral therapy (CBT) helps a young person recognize how their thoughts, feelings, and behaviors influence each other. A teen who automatically thinks “everyone hates me” learns to test that thought against evidence and replace it with something more accurate, which shifts both mood and behavior over time. Interpersonal therapy for adolescents (IPT-A) takes a different angle, focusing on the relationships and social situations most closely tied to the depressive episode. It teaches communication and problem-solving skills within those relationships.
Both approaches are supported by enough evidence to earn formal recommendations for adolescents. For younger children (under 12 or so), the evidence base is thinner, and no single therapy or medication has been singled out as clearly superior. That doesn’t mean treatment doesn’t help younger kids. It means the research hasn’t yet pinpointed a first-choice option the way it has for teens. A mental health professional experienced with this age group can tailor an approach based on the individual child.
What to Do With the Results
If the screening score lands at 10 or above, or if specific answers (especially the last question about self-harm) raise concern at any score level, the next step is a conversation with the child’s pediatrician or a mental health provider. Pediatricians are equipped to do a more thorough evaluation and can refer to a therapist or psychiatrist if needed. School counselors can also be a starting point, particularly if getting to an outside provider takes time.
