Abstract
Objective: Given the association between severe childhood trauma, adult somatization and complex post-traumatic stress disorder (cPTSD), the purpose of the present paper was to assess this syndrome and its clinical correlates in patients with somatization disorder (SD).
Methods: A total of 28 patients (82% women, mean age = 41.7±10.1 years) meeting DSM-IV criteria for SD as confirmed by the Structured Clinical Interview for DSM-IV, Axis I were compared to 28 age- and gender-matched patients with major depression, but without a lifetime diagnosis of SD. They completed the Structured Interview for Disorders of Extreme Stress, the Brief Symptom Inventory, the Inventory of Interpersonal Problems–Circumplex Scales, and the SF-36 Health Survey.
Results: Compared to the control group, SD patients had higher risks for current and lifetime diagnoses of cPTSD (odds ratio (OR) = 15.0, 95% confidence interval (CI) = 1.76–127.54; and OR = 8.33, 95%CI = 2.04–34.07, respectively). SD subjects with cPTSD had more psychological distress, more interpersonal problems and worse psychosocial functioning than those without the syndrome.
Conclusion: The concept of complex PTSD may hold clinical utility when applied to SD patients because it identifies a distinct subgroup characterized by severe psychosocial impairment. The diagnostic and therapeutic implications of the present findings are discussed.
