What is the definition of prototypes? How to classify prototypes of people with depression?

Very happy to know it and cheers.

I cannot thank you enough.

Prototypes are preliminary models or examples that represent a concept, allowing for testing and refinement before final production. In psychology, prototypes can refer to typical representations of mental health conditions, such as depression.

To classify prototypes of people with depression, researchers often use symptom-based categorizations, identifying common features such as emotional distress, cognitive patterns, and behavioral changes. These prototypes may include variations like "persistent depressive disorder" or "major depressive disorder," each characterized by specific symptoms and severity levels. Assessment tools, such as the DSM-5 criteria, help in identifying and classifying these prototypes effectively.
