Note. Q1 = 1st quartile, Q3 = 3rd quartile. Due to missing data, sample sizes of some variables are slightly reduced: parent race/ethnicity (n = 301), parent born in the United States (n = 308), parent age at screening (n = 306), ABAS-2 Communication (n = 301), ABAS-2 Self-Direction (n = 304) and Social (n = 302), PSS Total score (n =307). All other variables describe data from the total sample size (n = 309).
