Question: 1 / 425

How long must symptoms persist for a diagnosis of Persistent Depressive Disorder?

At least six months

At least one year

At least two years

For a diagnosis of Persistent Depressive Disorder, symptoms must persist for at least two years in adults (or one year in children and adolescents). This duration requirement is critical in differentiating Persistent Depressive Disorder from other depressive disorders, such as Major Depressive Disorder, which can occur in episodes of shorter duration. The chronic nature of Persistent Depressive Disorder is a defining characteristic, highlighting its long-term impact on the individual's functioning and well-being. This extended timeframe is necessary to establish that the symptoms are not just part of a transient mood disturbance but instead reflect a more enduring form of depression that requires a distinct approach to treatment and management.
