SIQA Psychometric Information
A Principal Components Analysis with Varimax rotation yielded a 9-factor solution, supporting the factor structure posited a priori. The 9-factor solution accounted for more than 75% of the variance. Loadings on the factors ranged from very good .63 to excellent .86. Internal consistency reliabilities for the factors are excellent, ranging from .91 to .97. (See Table 1 for details.)
