Stability of neuroticism and alexithymia in somatization.
The personality traits neuroticism and alexithymia have been hypothesized as predisposing factors for somatization. Stability over time is a basic assumption underlying any trait construct. Although there are considerable (and sometimes conflicting) data relevant to this issue, the stability of neuroticism and alexithymia has not been assessed in somatization. The main purpose of this study was to examine the temporal stability of neuroticism and alexithymia in patients presenting to their primary care physician with medically unexplained symptoms, and compare this to the stability of negative and positive affect, anxiety, and depression. A total number of 318 patients were assessed at baseline and at 6-months follow-up. Whereas the affective state dimensions changed significantly over the follow-up period, neuroticism and alexithymia were substantially stable.
