A - 23 Confirmatory Factor Analysis of the Concussion Profile (CP) Screen

Abstract Objective The Concussion Profile (CP)-screen is intended to assess symptom domains of concussion, including migraine, vestibular, ocular, mood/anxiety, and cognitive/fatigue domains. CP-screen was developed develop more targeted management by identifying presentation profiles. hypothesized profile structure the has not yet been psychometrically validated. An a priori five-factor (migraine; vestibular; ocular; mood/anxiety; cognitive/fatigue) hypothesized. Methods Three-hundred twenty-three patients (age M = 15.62 ± 4.03 years, 59% male; 74% sport-related) seen within 30 days concussion (M 7.58 6.10 days) completed medical history clinical interview at their first visit. Multiple confirmatory factor analyses (CFAs) items were estimated (using robust weighted least squares estimation). Results A CFA for each separately then estimated. Model fit evaluated using Comparative Fit Index [CFI], Tucker-Lewis [TLI], Root Mean Square Error Approximation [RMSEA], inspection model parameters (i.e., loadings, residuals, & correlations). had excellent fit, but correlations indicated second-order appropriate. Thus, final included first-order structure, with factors loading onto factor. All models good (CFI >0.965; TLI > 0.96; RMSEA <0.072), all loadings significant substantial (>0.63). Conclusions This study provide psychometric support CP-screen. These results also these profiles help target those concussions.
