- RPQ = Rivermead Post‑Concussion Symptoms Questionnaire, PCSI-P = Post‑Concussion Symptom Inventory Proxy Version, PHQ‑9 = Patient Health Questionnaire 9, GAD‑7 = Generalized Anxiety Disorder Scale 7. The PCSI-P total score represents the aggregate of the Physical, Emotional, Cognitive, and Fatigue scales. Bold values indicate high correlation coefficients (i.e., ϱ ≥ 0.50).
- Group comparisons showed that higher RPQ total and scale scores were associated with more severe TBI, incomplete recovery (i.e., KOSCHI score < 5b), presence of post-TBI sensory, cognitive, and/or physical problems, and the experience of pronounced symptoms of depression and anxiety. No significant differences in the RPQ total and scale scores were observed between boys and girls (see Additional file 1, Table S2)
