Demographic and alexithymia profile of low and high alexithymia groups.

TAS-20: twenty-item Toronto Alexithymia Scale; DIF: difficulty in identifying feelings; DDF: difficulty in describing feelings; EOT: externally oriented thinking. SD: standard deviation. Low Alexithymia (n = 20) and High Alexithymia (n = 20) groups were obtained by selecting volunteers with low or high total scores on the TAS-20. Participants with discrepant TAS-20 and DPCR scores were excluded (cf. Material and Methods). DPCR: Alexithymia Module of Diagnostic Criteria for Psychosomatic Research scores.
