For household income, a binomial variable (low-income = 0; non-low-income = 1) was created. Annual household income data were collected categorically: (i) <$US 10 000; (ii) $US 10 001–20 000; (iii) $US 20 001–30 000; (iv) $US 30 001–40 000; (v) $US 40 001–50 000; (vi) $US 50 001–60 000; (vii) $US 60 001–80 000; and (viii) >$US 80 000. Based on responses to the categorical annual household income question, participants were assigned an income-level based on the midpoint between the income range. For example, if a participant responded that her/his annual household income was between $US 10 001 and $US 20 000, s/he was assigned an income level of $US 15 000. This annual household income level was compared with the national poverty guidelines( 18 ) and, based on the number of individuals living in the household (another question on the caregiver assessment form), participants were classified is low-income or non-low-income.
Participants were classified as Black if their caregiver reported the child as being African, or African American, or both African or African American and another race/ethnicity.
