In order to test the appropriateness of data set for the factor analysis, the Kaiser-
Meyer-Olkin (KMO) measure of sampling adequacy and Bartlett’s test of sphericity were performed. As a
result of analyses, it was determined that the data set was appropriate for the factor analysis since the KMO
value was over 0.799 and 0.50, and the sphericity possibility of Bartlett’s test was at 0.05. Necessary
information concerning the reliability of the questionnaire form has been presented at Table 6, Table 7 and
Table 8.
