Multicenter Study Comparative Study Observational StudyComparison of the Neurobehavioral Symptom Inventory and the Rivermead Postconcussion Symptoms Questionnaire.
Objective: This study sought to determine the similarity of constructs measured by the Neurobehavioral Symptom Inventory (NSI) and Rivermead Postconcussive Symptoms Questionnaire (RPQ) and the potential for interchangeability of scores from the two scales. Setting: Three acute inpatient rehabilitation hospitals in the USA. Participants: 497 community dwelling persons with traumatic brain injury (TBI) who completed the NSI and the RPQ during the same assessment. ⋯ A crosswalk between the two measures was created by equating scores from the scales based on percentile ranks. Conclusion: Results indicate substantial conceptual and empirical overlap between the NSI and RPQ. The percentile crosswalk developed from this dataset may allow combined analysis of post-concussive symptoms from datasets that include either the NSI or the RPQ.
