What is the Neuropsychiatric Inventory (NPI)?

The NPI has served as an outcome measure in many pharmacologic and nonpharmacologic intervention studies.

Measuring behavior in your trial may provide critically important outcome data useful in understanding and explaining the value of treatment. The NPI is the behavior instrument most widely used in clinical trials of antidementia agents.

The NPI uses a screening strategy to minimize administration time, examining and scoring only those behavioral domains with positive responses to screening questions. Both the frequency and the severity of each behavior are determined. Information for the NPI is obtained from a caregiver familiar with the patient's behavior.
