Objective: The goal of this investigation was to pilot the Neuropsychiatric Inventory (NPI) among individuals with traumatic brain injury (TBI) and their caregivers, assessing its screen-metric approach. Design and Participants: Using the NPI, caregivers rated neurobehavioral disturbances in 51 individuals with moderate-to-severe TBI. The NPI was completed 1 or 2 years after the individuals were injured. Results: Caregivers reported the highest symptom levels for participants on Irritability/Lability, Apathy, and Agitation/Aggression, and rated greater levels of distress tied to those domains and to Dysphoria. Caregivers endorsing domain screening items endorsed significantly more metric items (vs. screen non-endorsers) within that domain, as would be expected if the screen accurately measured the psychopathology under consideration. In addition, the screen-metric yielded extremely low false-positive rates, although 5 of the 12 domains had elevated false-negative rates. Conclusions: Findings provide preliminary support for the accuracy of the NPI's screen-metric in this population and are consistent with prior work detailing common problematic neurobehavioral consequences of TBI. These results lay groundwork for research and clinical use of this measure in populations with TBI.
