All active respondents belonging to the Nationally Representative sample were invited to take the survey. Hence, Native Americans, LA County and California respondents were excluded. Invitees were divided into three waves, depending on whether they had previously answered SCPC/DCPC from 2014 to 2017. Invitees in wave 1 were those with most experience with SCPC/DCPC; invitees in wave 2 were those with some experience with SCPC/DCPC; invitees in wave 3 had no previous experience with SCPC/DCPC. These three waves were invited sequentially: wave 1 first, wave 2 next, and wave 3 at last.
