Which of the following is a diagnostic test for anxiety disorder?

A. Overreaction of a medical symptom. While individuals with illness anxiety disorder (IAD) may misinterpret normal bodily sensations as signs of serious illness, the key feature is excessive health-related worry in the absence of significant symptoms, rather than just overreacting to existing symptoms.

B. Faked symptoms. Feigning symptoms is characteristic of factitious disorder (formerly Munchausen syndrome) or malingering, where individuals intentionally produce or exaggerate symptoms for attention or external gain. In IAD, the concern is genuine but unfounded, rather than intentionally fabricated.

C. Abnormal voluntary motor or sensory dysfunction. This describes conversion disorder (functional neurological symptom disorder), where individuals experience neurological symptoms (e.g., paralysis, blindness, or seizures) without a medical explanation, typically triggered by psychological stress.

D. Worry about health despite no symptoms. Illness anxiety disorder (IAD) is marked by persistent, excessive fear of having a serious illness, despite minimal or no symptoms and repeated medical reassurance. Patients often engage in excessive health-related behaviors (e.g., frequent doctor visits, checking their body) or avoid medical care altogether due to fear of diagnosis.

A. Micromanages others. Individuals with obsessive-compulsive personality disorder (OCPD) exhibit excessive control and perfectionism, often micromanaging tasks and people to ensure everything is done "correctly." They struggle with delegating responsibilities because they believe others will not meet their high standards.

B. Perfectionist. Rigid perfectionism is a core feature of OCPD. Individuals set unrealistically high expectations for themselves and others, leading to chronic dissatisfaction, procrastination, and inefficiency because they fear making mistakes.

C. Workaholic. Those with OCPD are often preoccupied with work and productivity, sometimes neglecting personal relationships and leisure activities. They may prioritize tasks over social interactions, believing that relaxation is a sign of laziness.

D. Wants to be alone. Unlike schizoid personality disorder, individuals with OCPD do not prefer isolation. They often engage with others in structured environments but struggle in relationships due to their rigid expectations, stubbornness, and excessive control over details rather than a genuine desire to be alone.
