What is one method used in diagnosing depression?

Having five symptoms over a two-week period is a key criteria for diagnosing depression according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This criterion is grounded in clinical practice and helps professionals understand whether an individual meets the threshold for a depressive episode. The symptoms must cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. This structured approach offers a standardized way for mental health professionals to evaluate and diagnose depression, ensuring that the diagnosis is based on established guidelines.

In contrast, online self-assessments may provide preliminary insights but cannot replace a professional diagnosis. Observing behavior can offer valuable information regarding a patient's state of mind, but it is subjective and may not encompass all necessary criteria for a formal diagnosis. Similarly, analyzing social media usage could yield interesting data about an individual's mood or social connections, but it lacks the rigorous structure and clinical validation necessary for diagnosing depression.
