Figure 1. Cross-lagged analysis between ADHD and sleep disturbance in QLSCD.
Random-intercepts cross-lagged panel model of ADHD total score and sleep disturbance from ages 7 to 13 years in QLSCD (n=1,601). Standardized estimates (95%CIs) are presented. Solid lines represent statistically significant (p<0.05), whereas dashed lines present non-significant (p>0.05). Model fit: root mean square error of approximation (RMSEA)=0.04; comparative fit index (CFI)=0.98; Tucker-Lewis index (TLI)=0.96; standardized root mean square residual (SRMR)=0.04.
