  • Table shows the results of the exploratory factor analysis (principal axis factoring) with orthogonal varimax rotation of the six-factor solution using the factor, pcf command in Stata.

  • Rotated factor loadings: a measure of how much each item contributes to the factor. Loadings close to −1 or 1 indicate that the factor strongly affects the item and loadings close to 0 indicate that the factor has a weak effect on the item.

  • Item #9 and 10 were excluded from the analysis as explained in the Results section.

  • Uniqueness: shows the proportion of the item’s variance that is not explained by the factors
