Note. Results based on standardized variance method of identification. Bold numbers on the diagonal are estimated variances. Covariances are below the diagonal and correlations are above. Latent means set to zero at T1 in order to establish metric; subsequent means therefore reflect change from T1. IN=inattention; HI=hyperactivity/impulsivity; SCT=sluggish cognitive tempo; T1=preschool; T2=post-1st grade; T3=post-4th grade; T4=post-9th grade.
