Loadings are simply correlations between an item and a factor; therefore, they need to be statistically significant, and consequently, group size should be taken into account. Drs. Alsobrook and Pauls used an absolute value of 0.200 as a threshold for the interpretation of factor loadings. According to Stevens (4), a group size of 670 patients would be required for such a threshold. Drs. Alsobrook and Pauls included 85 patients, a group size that allows loadings of merely >0.556. Anyhow, regardless of the group size, loadings with values of 0.200 explain only as little as 4% of the shared variance between an item and a factor.
