Crosswalks in postconcussive symptom questionnaires

Takeaway

  • Neurobehavioral Symptom Inventory (NSI) and Rivermead Postconcussive Symptom Questionnaire (RPQ) have considerable overlap and measure the same overarching constructs. A new scale containing the best theoretical and psychometric items from the NSI and RPQ, the Brain Injury Symptom (BISx) Scale, is proposed for tracking symptoms and outcomes in brain injury rehabilitation.

Why this matters

  • Crosswalk tables may be helpful for clinicians and researchers to convert scores from one measure to the other.
