Note. Transformations for the observed maternal behavioral control (square root) and adherence (square root) variables were used in the aforementioned analyses; IQ based on WASI.
BRIEF = Behavioral Rating Inventory of Executive Function; EF = executive function; Beh. = behavioral; Psych. = psychological.
