A total of 439 participants responded to the
Internet survey. The survey was organized so that
respondents were first queried about content areas
and then about demographic information. The final
database included responses from 338 participants
who completed the entire survey, including demographic
information regarding gender, age, and
ethnicity, in addition to information on their
education, training, and experience. (Subsequent
interviews in this research program first queried
respondents about demographic information and
then on content areas. This sequencing allowed
those studies to compare respondents who completed
the interview from those who did not on
demographic variables. Since this survey queried
for demographic information at the end of the
interview, noncompleters were defined as those
who failed to provide demographic information.)
