2Q 9Q Depression Screening Test (Thai Department of Mental Health) with Instant Result

For: Anyone who suspects they may be depressed, about themselves · Takes 2 minutes · Reviewed by Dr. Pichayut Kasempukdeepong (Psychiatrist), 7 September 2026

The 2Q and 9Q (usually referred to together as 2Q 9Q) are the depression screening tools used by Thailand’s Department of Mental Health in hospitals and health centres nationwide. Two screening questions come first; if either applies, the 9-item 9Q, equivalent to the international PHQ-9, rates severity.

Depression very often goes hand in hand with alcohol and drug use, each feeding the other. If you or someone close to you has a substance problem, screening mood at the same time helps the doctor plan treatment for both. The result is a preliminary screen, not a diagnosis, and your answers are not stored.

It starts with 2 screening questions (2Q). If either applies, 9 more questions follow (9Q). All questions refer to the past 2 weeks, including today. Choose the answer that fits best.

Your answers are not stored or sent anywhere.

How Depression screening test (2Q 9Q) scores are interpreted

After you finish, your result is interpreted using the ranges below. The result is an initial screen, not a diagnosis.

ScoreLevel and what it means
0–6No or minimal depressive symptoms
Your answers show no tendency toward, or symptoms of, depression at the threshold of this screen. If you are under stress or using alcohol or drugs, mood can change quickly, so repeat the test in 2 weeks if you still feel low.
7–12Mild depressive symptoms
You have mild depressive symptoms. Look after your sleep and exercise, and cut down on alcohol or drugs, which make symptoms worse. If symptoms last more than 2 weeks or affect your daily life, talk to a professional.
13–18Moderate depressive symptoms
You have moderate depressive symptoms. We recommend seeing a psychiatrist for assessment and a treatment plan. Depression is treatable and does improve, especially when treated together with any substance use problem.
19–27Severe depressive symptoms
You have severe depressive symptoms and should see a psychiatrist soon rather than wait. Our medical team is available every day, 9:00 AM–5:00 PM. If you are in immediate danger, call 1669 or ask someone close to you to take you to the nearest hospital.
