N2 - An item response theory (IRT) model identified three dimensions assessed by the Toronto Alexithymia Scale (TAS) in s sample of 130 male applicants for inpatient care at a Veterans Administration (VA) medical center alcoholism, treatment program. A unidimensionai solution did not capture ail of alexithymia's theoretical features. Subjects with lower alexithymia scores gave positive responses to items tapping emotional awareness deficits; only those with higher alexithymia scores gave positive responses to items tapping external operative cognitive style. Thus, a total TAS score may not represent alexithymia accurately in substance-abusing patient populations.
