- Deviance: Behavior that significantly deviates from societal norms or expectations.
- Danger: The potential for harm to oneself or others.
- Distress: The emotional suffering or distress caused by the symptoms.
- Dysfunction: Impairment in social, occupational, or other important areas of functioning.
These four features—deviance, danger, distress, and dysfunction—are widely used to diagnose psychological disorders. Thus, the correct answer is (1) Deviance, danger, distress, dysfunction.
