Although there appear to be several affective and behavioural similari
ties between psychopathy and alexithymia, there have been few empirica
l investigations of the cooccurrence of these two constructs. In this
study, we determined their comorbidity in a sample of 37 female offend
ers. We also investigated their association with the use of affective
language in response to questions about an emotional event, and with t
heir propensity for violence. Extent of psychopathy and alexithymia we
re assessed with the Hare Psychopathy Checklist-Revised (PCL-R), and t
he Toronto Alexithymia Scale (TAS), respectively. Using standard cutof
f scores, 30% were identified as psychopaths, and 32% as alexithymics.
Three women were both psychopaths and alexithymics. The correlation b
etween PCL-R and TAS total scores was not significant, but the sociall
y deviant, impulsive factor of the PCL-R was significantly correlated
with the TAS items that reflect inability to discriminate feelings and
bodily sensations. Alexithymia, but not psychopathy, was negatively r
elated to measures of affective speech content. Both psychopathy and a
lexithymia were associated with a history of violence. In spite of sev
eral manifest similarities, psychopathy and alexithymia appear to be d
ifferent clinical constructs.
