Can scores on alexithymia distinguish patients with peptic ulcer and erosive gastritis?

This study examined alexithymic characteristics of 57 patients with peptic ulcer and 198 with erosive gastritis. The prevalence rate of alexithymia, as measured on the 20-item Toronto Alexithymia Scale, was significantly higher for the peptic ulcer group (51%) than for the erosive gastritis group (21%). Scores of the Profile of Mood States were significantly higher for the peptic ulcer group than for the erosive gastritis group. The alexithymia scores were significantly correlated with the scores on the Profile of Mood States. However, discriminant analysis indicated that the alexithymia scores could account for significant additional variance beyond mood states as measured by the Profile of Mood States.
