Factor analysis
In order to determine how many factors should be extracted from a factor analysis, the
scree plot and eigenvalues are usually inspected. Table 1 shows eigenvalues and the
percentage of variance for factors I–IV, (which were identical using both principal axis
factoring and principal components analysis), which indicated a two-factor solution.
However, in order to examine other solutions to compare with previous research, threeand
four-factor solutions were also investigated.
