Participants
The participants were students at a medium-sized southeast-
ern university.Responses from ten participants (10 %) were excluded
from analysis due to not meeting inclusion criteria or
because of missing data.A random number generator available
online at http://stattrek.com/Tables/Random.aspx was
used to select the last four digits of student identifica-
tion numbers.Participants' academic
levels ranged from freshmen through graduate student, with
14.0 % (n08) freshmen, 19.3 % (n011) sophomores, 15.8 %
(n09) juniors, 19.3 % (n011) seniors, and 31.6 % (n018)
graduate students.Because all students at the university are assigned an
identification number when they are admitted, the ID
number served as a method of randomly soliciting students for
participation.In terms of ethnicity,
84.5 % (n071) of participants reported their race as white/
Caucasian, 10.7 % (n09) as African American/black, 3.6 %
(n03) as Asian, 1.1 % as American Indian (n01).They were randomly solicited to participate
in the study using university identification numbers.Next, the university's student directory
was used to search for students by identification num-
ber.Females comprised 56.6 % (n047) of the
participants and males 43.4 % (n036).Students chosen to participate were contacted
through their university e-mail addresses.Of
the 2,755 questionnaires e-mailed to study participants,
100 (3.6 %) were returned.In order to achieve this
sample, 2,755 students were invited to participate.This yielded a total sample of
90 participants.The age of participants ranged from 18 to 58 years old
with a mean age of 25.86+-9.67 years.A sample size
of 200 students was sought.
