Note. Data from three studies were combined for the current analysis. Some data was unavailable due to variations in data collection across studies:

a,

the demographics form for Study A inquired about “sex” for youth and parents; Studies B and C inquired about “gender” and provided an “other” option with space to self-describe, though no parent participants selected that gender option for themselves or their child.

b,

only three income categories were presented in Study A;

c,

the first edition of the Social Responsiveness Scale (used in Study A) only distinguishes three severity categories (mild and moderate are combined).
