Note.

^*indicates that the measure was not collected for Sample 3.

^{^}indicates that the measure was not collected for Sample 1.

All percentages are based on the original sample size at the first wave of data collection (N = 413), although some missingness was planned at 42 months since these data were not collected for Sample 3. Pos. Parenting refers to the Observed Positive Parenting composite that was formed based on observed parental involvement and responsiveness during the home visit. CHAOS refers to the Confusion, Hubbub, and Order Scale²⁶.
