Path diagram of full measurement and structural model including an EEG residual factor removing the mTBI group mean differences when predicting each of the four PCL factors. This model was fit separately for Alpha, Beta, Delta, and Theta frequency factors.
Note: μRF, μLF, μRO, μLO = localized EEG factor scores with the corresponding error terms; EEG = latent EEG factor from the four localized factors; EEG_R = residual latent EEG factor; TBI = 0/1 mTBI status; v1–v17 = 17 PCL item scores; r1–r17 = error terms for 17 PCL items; Re-exp = re-experiencing symptom factor; Avoid = avoidance symptom factor; Numb = numbing symptom factor; HyperA = Hyperarousal symptom factor.
