Which disorder is defined by uncontrollable thoughts that lead to repetitive behaviors designed to relieve anxiety?

• A. General Anxiety Disorder
• B. OCD
• C. PTSD
• D. Social Anxiety Disorder

Answer: (B)

Uncontrollable thoughts that drive repetitive behaviors aimed at reducing anxiety are characteristic of obsessive-compulsive disorder. In OCD, these intrusive, unwanted thoughts—called obsessions—create significant distress. To cope, the person performs rituals or mental acts—called compulsions—that are meant to lessen that anxiety or prevent a feared outcome. These behaviors are time-consuming and interfere with daily life, and even though the person may recognize them as excessive, they feel compelled to perform them.

This pattern helps differentiate it from other anxiety-related disorders. Generalized anxiety disorder involves pervasive worry across many areas without the presence of ritualized actions. PTSD centers on trauma-related symptoms such as flashbacks and avoidance. Social anxiety disorder involves intense fear of social scrutiny rather than compulsive rituals. The combination of obsessions and compulsions specifically points to OCD.
