Continuous variables analyzed using independent t-test. Categorical variables analyzed using χ2-test
SD, standard deviation
aThe variable was dichotomized as “two parents” (married or cohabiting) or “single parent” (unmarried, divorced, or widowed)
bThe variable was recoded into four categories: “none,” “1,” “2,” or “ ≥ 3” (3, 4, 5, > 5)
cThe variable was dichotomized as “yes” (moved 1 time, 2–4 times, ≥ 5 times) or “no.”
dThe variable was recoded into three categories: “0–4 days” (none, 1–4 days), “5–10 days” (5–7 days, 8–10 days), or “ > 10 days.”
