Tables I-IV show the findings of the 19 attitudinal
statements. Although a seven-point Likert scale was used
for these questions, the tables report only the percentages of
individuals who indicated some level of agreement or
disagreement with each statement. Respondents who
indicated no opinion (4 on the seven-point scale) are not
included in the percentage totals, but are included in
calculating the mean for each question. The percentage who
agreed with the statement would include everyone who
indicated “strongly agree,” “moderately agree,” and “slightly
agree.” The reverse would be true for the percentage of
respondents disagreeing with the statement. Means were
calculated for each question and t-tests were used to
determine significant differences in responses between the
1993 and 2004 studies.
