In a recent issue of the ARCHIVES, Simon and Gureje1 reported on the stability of the symptoms and diagnosis of somatization disorder (SD). The authors found that the diagnosis of SD was not stable and that progressively, significant discrepancies were found in somatic symptom reporting.
Given that some of their data seemed to be restricted in range, we wondered whether alternative conceptualizations of somatization2,3 would yield higher stability estimates. To explore this issue, we reanalyzed the data reported by the authors in their Table 1 and Table 2, using a Monte Carlo method4 for estimating the stability of somatization over time.
