Four self-screens cover depression, anxiety and alcohol risk. Every result includes a score range, plain-language interpretation and next step.
Depression
PHQ-22 items · 1 minPHQ-2 depression screenA two-question first-pass screen for depressed mood and loss of interest. It is useful when you want a very quick check, not a diagnosis.Start assessment →PHQ-99 items · 3 minPHQ-9 depression symptom scaleA widely used nine-question screen that groups recent depressive symptoms into a severity band. Item 9 is a safety signal regardless of the total.Start assessment →
Anxiety and alcohol use
GAD-77 items · 2 minGAD-7 anxiety symptom scaleA seven-question screen for the frequency and severity of recent anxiety symptoms.Start assessment →AUDIT-C3 items · 2 minAUDIT-C alcohol screenThree questions about alcohol use in the past year. A Singapore standard drink contains about 10 g of alcohol: roughly 330 mL beer, 100 mL wine or 30 mL spirits.Start assessment →
Clinician-led
Psychosis and cognitive assessments should not become casual online self-tests
These tools depend on observation, interview, clock drawing or standardized administration, and some have licensing limits. An official clinical pathway is safer than a misleading online “diagnosis score.”

MoCA
Covers more cognitive domains. It must use the official version and standardized process; this site does not copy or independently digitize it.

PQ-B
This 21-item self-report is only stage one. A positive screen does not mean schizophrenia and must be followed by a clinical interview.

PANSS
Rates positive, negative and general symptoms in established schizophrenia. It is not a public screening or diagnostic test.

Which few scales are enough for each need?
The shortlist is based on complementary purpose, not the number of available questionnaires.
| What you need to understand | Shortlist | How to choose |
|---|---|---|
| Depression screening | PHQ-2 → PHQ-9 | Use 2 items for a first pass; move to the 9-item version after a positive screen or when a fuller severity picture is needed. |
| Anxiety | GAD-7 | One classic short scale is enough. A clinician can add panic, social-anxiety or trauma-specific assessment when needed. |
| Alcohol risk | AUDIT-C | Three items are enough for the first step; use the full 10-item AUDIT and interview only after a positive result. |
| Cognition / dementia | Mini-Cog or MoCA | Mini-Cog is faster; MoCA is broader. Both should follow their official clinician-administered process. |
| Psychosis / schizophrenia | PQ-B → interview; PANSS after diagnosis | PQ-B is only stage one of a two-stage screen. PANSS measures symptom severity in established schizophrenia and is not a self-diagnosis tool. |
Why are some famous names not online tests here?
A classic depression scale, but licensed and paid; PHQ-9 meets this public screening need.
A familiar cognitive test, but commercially licensed; its questions are not reproduced here.
Its owner expressly prohibits posting the test online or creating an independent electronic version, so this directory links to the official clinical route.
Licensed and interview-rated. It measures schizophrenia symptom severity and is not suitable for public self-testing.
