Concussion Symptom Inventory: an empirically derived scale for monitoring resolution of symptoms following sport-related concussion
Randolph C et al. – A new Concussion Symptom Inventory is presented and recommended as a research and clinical tool for monitoring recovery from sport-related concussion. Methods- Data analysis of a large data set for existing scales from 3 separate case–control studies
- Derivation of a sensitive and efficient scale for this application by eliminating items insensitive to concussion
- Collection of baseline data from symptom checklists with 27 symptom variables for 16,350 high school and college athletes
- Follow-up data from 641 athletes who subsequently incurred a concussion
- Administration of symptom checklists at baseline (preseason), immediately post-concussion, post-game, and at 1, 3, and 5 days post-injury
Results- Effect-size analyses resulted in retention of only 12 of 27 variables
- Receiver-operating characteristic analyses confirmed that reduction in items did not reduce sensitivity or specificity
