Methodology
Sample Recruitment
During the initial recruitment phase of the AmeriSpeak
®
panel,
randomly selected U.S. households were sampled with a known,
non-zero probability of selection from the NORC National Sample
Frame and then contacted by U.S. mail, email, telephone, and field
interviewers (face-to-face). The panel provides sample coverage of
approximately 97% of the U.S. household population. Those excluded
from the sample include people with P.O. Box only addresses, some
addresses not listed in the USPS Delivery Sequence File, and some
newly constructed dwellings.
For the current survey, adult panel members age 18 to 22 were
randomly drawn from AmeriSpeak. To recruit teen respondents, adult
panel members living in households with minors were randomly drawn
from AmeriSpeak, and permission was sought from a parent or guard-
ian to survey their teenager. If a given panelist had multiple teens
at home, one teen was randomly selected to participate.
Oversamples of African American and Latino youth were conducted
sufficient to generate a total unweighted sample size of more than 300
African Americans and more than 350 Hispanics. For analyses among
the general population, African American and Latino respondents were
weighted down to their representative proportion, according to the
most recent Census.
Panelists were offered modest incentives to participate, in the form
of a cash equivalent ranging in value from $2-10 (adults were offered
higher incentives than teens and those from hard-to-reach groups
were offered higher incentives than others).
