The comparison of the relationships between the perception of
reliability and the use of health information sources is shown in Table
4. The values (bolded) in the main diagonal of the correlation
coefficients matrix are the correlations between each information
source’s own perception of reliability and use. The correlation
coefficients in the lower left side of the main diagonal express the
correlations between the perception of reliability of health information
sources and the use of health information sources; the upper-right side
of the main diagonal is the opposite. For example, the value 0.51 in the
first column and second row of the correlation coefficients matrix was
the correlation coefficient between “perception of radio reliability
and television usage.” The 0.29 value in the first row of the second
column, which is symmetrical, was the correlation coefficient between
“radio use and perception of television reliability.” Generally, the
correlation coefficients between the perception of reliability and the
use of the same information sources were the highest. Although all of
these correlations were statistically significant: the highest
correlation among these was between the reliability perception and the
use of television (r =0.63; p <0.001) while the
lowest correlation was between the reliability perception and the use of
newspapers/magazines (r =0.36; p <0.001).
