title: Three Scoring Approaches to the Neurobehavioral Symptom Inventory for Measuring Clinical Change in Service Members Receiving Intensive Treatment for Combat-Related mTBI.
abstract: OBJECTIVE
  To examine the use of the Neurobehavioral Symptom Inventory to measure clinical changes over time in a population of US service members undergoing treatment of mild traumatic brain injury and comorbid psychological health conditions.
  
  
  METHODS
  A 4-week, 8-hour per day, intensive, outpatient, interdisciplinary, comprehensive treatment program at the National Intrepid Center of Excellence in Bethesda, Maryland.
  
  
  METHODS
  Three hundred fourteen active-duty service members being treated for combat-related comorbid mild traumatic brain injury and psychological health conditions.
  
  
  METHODS
  Repeated-measures, retrospective analysis of a single-group using a pretest-posttest treatment design.
  
  
  METHODS
  Three Neurobehavioral Symptom Inventory scoring methods: (1) a total summated score, (2) the 3-factor method, and (3) the 4-factor method (with and without orphan items).
  
  
  RESULTS
  All 3 scoring methods yielded statistically significant within-subject changes between admission and discharge. The evaluation of effect sizes indicated that the 3 different Neurobehavioral Symptom Inventory scoring methods were comparable.
  
  
  CONCLUSIONS
  Findings indicate that the different scoring methods all have potential for assessing clinical changes in symptoms for groups of patients undergoing treatment, with no clear advantage with any one method.
