Note: The rotated factor loadings show which variables represent each factor. Kaiser normalization was on in this model. All but GPS item 14 (derealization) had acceptable factor loadings greater than 0.4 (Pituch & Stevens, 2016). All but GPS item 18 (substance use) had the acceptable uniqueness values < 0.6.
