title: Factor analysis of the Rivermead Post-Concussion Symptoms Questionnaire in mild-to-moderate traumatic brain injury patients.
abstract: Posttraumatic brain injury patients with depressive symptoms were compared with nondepressed mild and moderate traumatic brain injury (TBI) patients based on their scores on the Rivermead Post-Concussion Symptoms Questionnaire (RPCSQ). A factor analysis demonstrated that the items of the RPCSQ loaded into three factors: mood and cognition, general somatic, and visual somatic symptom groups. Factor scores based on this model were calculated for each group and it was found that depressed subjects reported a greater severity of all three symptom groups compared to nondepressed patients. These results suggest that depression post-TBI may influence patient perception of postconcussion symptoms.
