Confirmatory Factor Analysis and Concurrent Validity of the Concussion Clinical Profiles Screening Tool (CP Screen)

The factor structure of the Concussion Clinical Profiles Screen (CP Screen) has not been empirically evaluated. In this study, 323 patients (59% male; 74% sport-related) completed CP Screen, ImPACT, and Vestibular/Ocular-Motor Screening (VOMS) at initial clinical visit within 30 days of concussion (M = 7.58±/-6.10 days). A second-order model best fit the data, with cognitive-fatigue, migraine, and ocular factors comprising a second-order factor. Loadings were all significant/substantial. Vestibular, ocular, and cognitive-fatigue factors all significantly (βs = .15-.44 ps ≤ .01) predicted assessments in similar domains, supporting concurrent validity. This study provides initial psychometric support for the structure of the CP-screen.
