Neurobehavioral Functioning Inventory

Neurobehavioral Functioning Inventory (NFI) is an outcome measure and was developed to collect information about patients’ post-injury behaviours (in patients with TBI and other neurological disorders) from relatives.[1]

This scale consists of 76 items grouped into six independent scales:

  • Depression
  • Somatic
  • Memory/Attention
  • Communication
  • Aggression
  • Motor[1]

Some of the items are:

  • Feels hopeless
  • Feels worthless
  • Frustrated
  • Lonely
  • No confidence
  • Forgets phone numbers
  • Forgets to do chores or work
  • Forgets to take medication
  • Forgets yesterday’s events
  • Forgets what he or she reads
  • Late for appointments
  • Loses track of time, day, or date
  • Loses way, gets lost
  • Misplaces things
  • Trouble following instructions [1]

Respondents rate the frequency of problem occurrence on a 5-point scale: (1) never, (2) rarely, (3) sometimes, (4) often, or (5) always.[2]

Evidence[edit | edit source]

Reliability[edit | edit source]

Neurobehavioral Functioning Inventory Depression Scale has been shown to be reliable for people with traumatic brain injury. Chronbach's alpha analysis revealed acceptably high internal reliability for all scales ranging from 0.86 to 0.95.[1]

Validity[edit | edit source]

Validity of NIF scale has not yet to be elucidated.[3]

Miscellaneous[edit | edit source]

This scale is available in Spanish, French, German and Italian.[3]
