Introduction to the Neurobehavioral Functioning Inventory

Based on more than a decade of research, the Neurobehavioral Functioning Inventory (NFI) was designed to collect information on a wide spectrum of behaviors and symptoms commonly associated with brain injury. The NFI provides information regarding the frequency of difficulties allowing measurement of change over time. Two versions of the NFI are available, one for completion by family members, another for completion by the person with the injury. Both versions address identical content areas. The responses of family members and the patient can be compared to identify differing perceptions.

The items of the NFI address problems commonly encountered in daily living. For example, inquiry is made regarding the extent to which people misplace things, lose track of time, miss appointments, forget phone numbers, and have difficulty with word finding. Other items address emotional and behavioral issues like breaking or throwing things, feeling hopeless, restlessness, arguing, and threatening others. The broad selection of items has contributed to the measure's use in evaluating health related quality of life. In 1996, the NFI was added to the postacute follow-up protocol for the NIDRR brain injury model systems programs.
