For analyses including data from both mothers and fathers Level 2 N = 160, Level 1 n = 1,915. For analyses including data from mothers only Level 2 N = 158, Level 1 n = 1,561. Interaction variables are centered to their mean. Supervision was measured on a 1–7 scale, in which 7 was the highest level of supervision. 7 = mother within 6 feet of child, not engaged in other activity; 6 = mother within 6 feet of child, engaged in other activity; 5 = mother and child > 6 feet apart, child has mother's full attention; 4 = mother and child > 6 feet apart, child does not have mother's attention; 3 = mother and child > 6 feet apart, no visual contact but there is auditory contact; 2 = no visual or auditory contact with child, could reach child within 30 s; 1 = no visual or auditory contact, could not reach child within 30 s.
