SMU AND ADHD-SYMPTOMS 151 5 Figure A5.1 Simplified Illustration of the Five-Variable Random Intercept Cross-Lagged Panel Model Notes. Circles in the between-area represent random intercepts (RI), which were extracted from their three respective computed factor scores (not shown in figure). Circles in the within-area represent within-person values (W), which were extracted from their respective computed factor score (not shown in figure). Black arrows represent cross-lagged and auto-regressive relations. All possible cross-lagged relations were specified for control purposes (e.g., attention deficits at T1 on impulsivity at T2). Light gray arrows represent (residual) correlations.
