![Resize Image](../images/common/icon_depression-diagnosis.png)
The Depression Check Diagnostic Test is a self-check tool that allows you to self-diagnose depression just by answering simple questions. We use the diagnostic criteria of the self-administered depression screening tool PHQ-9 (Patient Health Questionnaire-9).
How to Use
- Enter your "Age," "Age of Onset," "Confirmation of Symptoms in Multiple Environments," "Functional Impairment," "Inattention Symptoms," and "Hyperactivity/Impulsivity Symptoms."
- The "Diagnosis Result," "Recommended Action," "Number of Inattention Symptoms," and "Number of Hyperactivity/Impulsivity Symptoms" will be automatically calculated.
What is ADHD (Attention-Deficit/Hyperactivity Disorder)?
ADHD (Attention-Deficit/Hyperactivity Disorder) is a developmental disorder characterized by persistent symptoms of inattention, hyperactivity, and impulsivity that affect an individual's daily life and social functioning.
Main Symptoms
- Inattention: Difficulty sustaining focus, frequent forgetfulness, poor organization, etc.
- Hyperactivity: Restlessness, constant movement
- Impulsivity: Acting without thinking, difficulty waiting for turns
Types of ADHD
- Predominantly Inattentive Type (ADHD-I): Primarily inattentive symptoms
- Predominantly Hyperactive-Impulsive Type (ADHD-HI): Prominent hyperactivity and impulsivity
- Combined Type (ADHD-C): Both inattentive and hyperactive-impulsive symptoms
Diagnostic Criteria (Based on DSM-5)
- Symptoms must have been present before the age of 12
- Symptoms must be observed in multiple environments (home, school, workplace, etc.)
- Clear functional impairment in academic, occupational, or interpersonal settings
Diagnosis Process
Depression Diagnosis involves interviews, behavioral observations, psychological testing, and screening tests. Differential diagnosis from other mental disorders is also crucial.
Treatment and Support
- Medication (e.g., methylphenidate, atomoxetine)
- Cognitive Behavioral Therapy (CBT)
- Adjustments and support in daily life
With proper treatment and support, individuals with ADHD can improve their quality of life.
What is the DSM-5 Diagnostic Logic for ADHD?
1. Symptom Criteria

Symptoms must be observed in at least two different environments (e.g., home, school, workplace).
4. Clear Functional Impairment
Symptoms must cause clear impairment in academic, occupational, or interpersonal functioning.
5. Symptoms Not Explained by Other Disorders
Symptoms cannot be better explained by other mental disorders such as schizophrenia, mood disorders, or anxiety disorders.
Summary of Diagnostic Logic
All criteria must be met.
- Number of inattention or hyperactivity-impulsivity symptoms meets the criteria
- Presence of symptoms before age 12
- Confirmation of symptoms in multiple settings
- Clear functional impairment
- Symptoms not explained by other disorders
Based on this diagnostic logic, accurate evaluation and diagnosis are conducted.
