There are several tests and assessments that can be used to diagnose depression. The most common type of test is a self-report questionnaire, where the person being tested answers questions about their symptoms and how they have been feeling. Some examples of self-report depression tests include:

1. The Beck Depression Inventory (BDI) is a commonly used self-report test that measures the severity of depression symptoms.

2. The Patient Health Questionnaire-9 (PHQ-9) is another self-report test that screens for depression and can be used to monitor the severity of symptoms over time. Click here to take the Depression test.

3. The Zung Self-Rating Depression Scale is a self-report test that assesses the severity of depression symptoms and can be used to diagnose major depressive disorder.

In addition to self-report tests, a mental health professional may also use clinical interviews and observation to diagnose depression. During a clinical interview, the mental health professional will ask questions about the person's symptoms, medical history, and family history, among other things. Observations of the person's behavior and demeanor may also be used to diagnose depression.

It's important to note that self-report tests are not a replacement for a formal evaluation by a mental health professional. If you think you may be experiencing depression, it's best to speak with a mental health professional who can accurately diagnose and treat your condition.
