Items corresponding to each factor are listed according to the strength of their factor loading
Items deemed problematic are underlined
The results marked in bold correspond to the highest factor loading value per item, complexity and CL ratio values above the recommended, evidencing cross-loading
PI, perceived infectability; GA, germ aversion; CL ratio, primary/secondary loading; LL, loading below 0.5; CL, cross-loading
