The principal component with varimax rotation method was used to identify the 2
major factors with eigen values >1. The factor loading
of each corresponding item was between 0.63
and 0.85, which is >0.5, indicating that each item
is homogeneous with the total scale. The variance of
factor 1 was 35.21%, that of factor 2 was 32.18%,
and the combined self-efficacy variance was 67.39%
(Table 3). The mean score for factor 1 was 21.20
(SD=6.13), while the mean score for factor 2 was
19.27(SD=7.27).
