  1. Note: (R) indicates item is reverse coded. For oblique rotations (oblimin in SPSS) the loadings and correlations are distinct. The pattern matrix depicts the loadings of the variables on the factors. Each row of the pattern matrix is essentially a regression equation where the standardized observed variable is expressed as a function of the factors. The loadings are the regression coefficients. The structure matrix holds the correlations between the variables and the factors
