Surveys
The Bem gender region stock (BSRI), the brand new Italian language kind of the latest directory out of Scientific profile Accentuations (IKP; 27 the fresh NEO Four-Basis Catalog (NEO-FFI 28 ,) and Toronto Alexithymia level (TAS-20 30 , are considered for the for each user.

Additional Desk dos suggests this new would mean and you may common deviations to own the concerning your domains laid out above (BSRI, ICP, NEO-FFI, and you can TAS-20) for all groups.
