What is Depression?

Depression (Depression) is a serious mental health disorder that affects a person's emotions, thoughts, and behaviors. Unlike the usual feeling of sadness, the symptoms of depression often last for a long time and can significantly affect daily life.

People with depression may feel prolonged sadness, lose interest in activities they once enjoyed, feel hopeless or worthless. In addition, they may experience problems with sleep, loss of appetite, fatigue, and sometimes thoughts about death. Depression can occur at any age and in any gender. The causes are often related to multiple factors such as genetics, biological, psychological, and environmental factors.

PHQ-9 Depression Assessment

PHQ-9 (Patient Health Questionnaire-9) is a questionnaire consisting of 9 items that help assess the severity of depression.

This tool is widely used in hospitals and clinics for initial screening of depression.

PHQ-9 Scoring Scale

• Never = 0
• Several days = 1
• Quite often = 2
• Nearly every day = 3

Depression Severity Based on Score

• 5–9 points: mild depression
• 10–14 points: moderate depression
• 15 points or more: severe depression

PHQ-9 helps with initial assessment but does not replace a doctor's diagnosis.

Depression is a mental health issue that can affect both the body and mind. However, with early recognition of symptoms, timely support, and appropriate treatment methods, patients can significantly improve their quality of life. Raising awareness about depression and using tools like PHQ-9 is an important step in taking care of one's mental health and the community.
