Which of the following is NOT one of the four criteria used to define abnormality?

The criterion "despair" is not one of the four criteria traditionally used to define abnormality in psychological contexts. The recognized criteria typically include:

1. Deviation - This refers to behavior or thoughts that are considered statistically rare or outside societal norms.
2. Dysfunction - This criterion assesses how a person's behavior interferes with daily functioning, affecting their ability to perform normal activities.
3. Dangerousness - This involves evaluating whether a person's behaviors pose a risk of harm to themselves or others.

While despair can coexist with various mental health issues, it does not serve as a standalone criterion for defining abnormal behavior. By recognizing the established criteria, one can better understand how mental health professionals assess and diagnose psychological disorders.
