Depression among teenagers is a growing concern, affecting millions of adolescents worldwide. Identifying depression early can lead to effective treatment and improved mental health outcomes. To aid in diagnosis, mental health professionals use standardized depression tests. These assessments help determine the severity of depressive symptoms and guide treatment plans.
This article explores 3 commonly used teenage depression tests:
The Patient Health Questionnaire-9 for Adolescents (PHQ-9A)
The Children’s Depression Inventory (CDI-2)
The Beck Depression Inventory (BDI-II)
Each of these tests has unique features and applications, helping healthcare providers assess teenage depression effectively.
1. The Patient Health Questionnaire-9 for Adolescents (PHQ-9A)
Overview
The PHQ-9A is a modified version of the PHQ-9, specifically designed for adolescents. It is widely used in schools, pediatric clinics, and mental health facilities as a screening tool for depression.
Structure and Questions
The PHQ-9A consists of nine questions, each corresponding to the symptoms of major depressive disorder as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The questions assess how frequently the adolescent has experienced symptoms like:
- Little interest or pleasure in activities
- Feeling down, depressed, or hopeless
- Trouble sleeping or sleeping too much
- Fatigue or lack of energy
- Poor appetite or overeating
- Feeling bad about oneself
- Difficulty concentrating
- Moving or speaking slowly, or feeling restless
- Thoughts of self-harm or suicide
Each question is rated on a scale from 0 (not at all) to 3 (nearly every day), giving a total possible score of 27.
Interpretation of Results
- 0–4: Minimal or no depression
- 5–9: Mild depression
- 10–14: Moderate depression
- 15–19: Moderately severe depression
- 20–27: Severe depression
If an adolescent scores 10 or above, further evaluation by a mental health professional is recommended. Additionally, if a teen indicates suicidal thoughts (question 9), immediate intervention is necessary.
Strengths and Limitations
Strengths:
- Quick and easy to administer (5 minutes)
- Validated for use in adolescents
- Free and widely available
Limitations:
- Self-reported, which may lead to underreporting or exaggeration
- Does not assess underlying causes of depression
2. The Children’s Depression Inventory (CDI-2)
Overview
The Children’s Depression Inventory (CDI-2) is a widely used assessment tool designed for children and adolescents aged 7–17 years. Developed by Maria Kovacs, it evaluates depressive symptoms over the past two weeks.
Structure and Questions
The CDI-2 comes in two formats:
- Self-report form: Completed by the adolescent
- Parent/Teacher report form: Filled out by a caregiver or teacher
The test consists of 28 multiple-choice questions, each with three possible answers that reflect different levels of severity. Examples include:
- “I am sad once in a while” (mild)
- “I am sad many times” (moderate)
- “I am sad all the time” (severe)
It assesses five key areas:
- Negative mood (e.g., feelings of sadness or guilt)
- Interpersonal problems (e.g., trouble making or keeping friends)
- Ineffectiveness (e.g., feeling inadequate)
- Anhedonia (e.g., loss of interest in enjoyable activities)
- Negative self-esteem (e.g., feeling worthless)
Interpretation of Results
The CDI-2 generates a total score, which is compared to standardized norms. Higher scores indicate greater levels of depression, requiring further clinical evaluation.
Strengths and Limitations
Strengths:
- Measures multiple aspects of depression
- Can be completed in 10–15 minutes
- Includes parent/teacher assessments for a broader perspective
Limitations:
- Longer than the PHQ-9A
- Some children may struggle to understand certain questions
- Self-reported, which may lead to biased results
3. The Beck Depression Inventory (BDI-II)
Overview
The Beck Depression Inventory (BDI-II) is one of the most widely used depression screening tools worldwide. Originally designed for adults, it has been adapted for use in adolescents aged 13 and older.
Structure and Questions
The BDI-II consists of 21 multiple-choice questions, each assessing different symptoms of depression. Each item has four response options, ranked from 0 (no symptoms) to 3 (severe symptoms). The total score ranges from 0 to 63.
The questions cover a wide range of depressive symptoms, including:
- Sadness
- Hopelessness
- Loss of pleasure in activities
- Sleep disturbances
- Changes in appetite
- Self-criticism
- Thoughts of death or suicide
Interpretation of Results
- 0–13: Minimal depression
- 14–19: Mild depression
- 20–28: Moderate depression
- 29–63: Severe depression
Strengths and Limitations
Strengths:
- Provides a detailed assessment of depression severity
- Well-validated and widely used
- Covers both emotional and physical symptoms
Limitations:
- Longer than the PHQ-9A and CDI-2 (takes 10–20 minutes)
- Requires a mental health professional for proper interpretation
- More appropriate for older teenagers (13+), rather than younger adolescents
Choosing the Right Depression Test for Teenagers
Each of these tests has its strengths, and choosing the most appropriate one depends on the situation:
For quick screenings: The PHQ-9A is the best choice due to its short format and ease of use.
For in-depth assessment: The CDI-2 provides a more detailed look at depressive symptoms, especially in younger adolescents.
For clinical evaluation: The BDI-II is ideal for older teens receiving professional mental health care.
The Importance of Professional Diagnosis
While these tests are valuable tools, they do not provide a formal diagnosis of depression. Only a qualified mental health professional can diagnose depression based on clinical interviews, history, and additional assessments. If a teenager shows signs of depression, seeking professional help is crucial.
Conclusion
Teenage depression is a serious mental health condition that requires prompt attention. The PHQ-9A, CDI-2, and BDI-II are three commonly used tools that help assess depressive symptoms and guide intervention. Early detection through these tests can lead to effective treatment, improved well-being, and a brighter future for affected teenagers. If you suspect a teen is struggling with depression, encourage them to seek support from a mental health professional, teacher, or trusted adult.
