Interpreting patient-rated outcome measures in adolescent patients following concussion.

Objective: To estimate scale scores for patient-reported outcome (PRO) measures that classify patients as improved or unimproved at days 3 and 10 post-concussion.

Methods: Data from 187 adolescent patients who sustained a concussion (150 males, 32 females, 5 not reported) were analyzed. Patients completed the Pediatric Quality of Life Inventory (PedsQL), PedsQL Multidimensional Fatigue Scale (MFS), Headache Impact Test (HIT-6), and Global Rating of Change (GROC) on days 3 and 10 post-concussion.
