Notes: Outcome rates are computed according to guidelines from the American Association for Public Opinion Research (2016). The respective rates are calculated as shown below, where I is a completed interview, P is a partial interview, R is a known refusal, NC is a noncontact (someone referred by a parent respondent and selected by the NSM algorithm who failed to respond to the research team's invitation after several contact attempts), and O is other (the parent respondent provided invalid referral information on the alter).
RR1=I / ((I + P) + (R + NC + O)).
RR2=(I + P) / ((I + P) + (R + NC + O)).
Refusal Rate=R / ((I + P) + (R + NC + O)).
Contact Rate=(I + P) + R + O / ((I + P) + R + O + NC).
