The definitions provided describe Personality Disorder as involving disturbances in multiple domains including which of the following?

• A. Cognition, affect, interpersonal functioning, and impulse control
• B. Mood, sleep, appetite, and energy
• C. Vision, hearing, and balance
• D. Motor control, reflexes, and coordination

Answer: (A)

Personality disorders are defined by enduring patterns that affect how a person thinks (cognition), feels (affect), relates to others (interpersonal functioning), and exercises self-control (impulse control). This multi-domain disturbance is central to the description of these disorders, which is why the option listing cognition, affect, interpersonal functioning, and impulse control is the best fit.

The other options point to areas not central to personality pathology: mood, sleep, appetite, and energy are more about mood or medical symptoms; vision/hearing/balance are sensory functions; and motor control/reflexes/coordination are neurological/motor domains.
