title: Alexithymia in DSM-IV disorder: comparative evaluation of somatoform disorder, panic disorder, obsessive-compulsive disorder, and depression.
abstract: The purpose of this study was a direct comparative evaluation of alexithymia in patients with somatoform disorder, panic disorder, obsessive-compulsive disorder, and depression, taking into account the multidimensionality of the alexithymia construct. The authors administered the Structured Clinical Interview for DSM-IV (SCID) and the Toronto Alexithymia Scale (TAS-20) to a sample of 234 subjects. Panic disorder, but no other diagnosis, was significantly related to lower TAS-20 total scores (P=0.000). Regarding TAS-20 subfactors, Factor 1 was significantly associated with somatoform disorder (P=0.006) and depression (P=0.002), Factor 2 was significantly associated with depression (P=0.025), and Factor 3 was significantly associated with obsessive-compulsive disorder (P=0.001), whereas panic disorder showed a significant negative correlation with Factor 3 (P=0.001). The relationships of the three subfactors with various DSM-IV diagnoses and sociodemographic variables emphasize the multidimensionality of alexithymia.
