Major depressive disorder


Somatization Disorder is a rare psychological condition that affects approximately 2% of women and 0.2% of men in the United States. This archival study was undertaken to develop base rates for the prevalence of Major Depressive Disorder among a group of outpatients previously diagnosed with Somatization Disorder in a community mental health clinic. The Shedler Quick PsychoDiagnostics Panel (QPD Panel) was utilized to sort patients into a Somatization Disorder and control group. A 2 x 2 Pearson's Chi-Square Test of Independence was utilized. In this study, 44% of patients who were identified as having Somatization Disorder were also diagnosed with Major Depressive Disorder. The implications for these results are discussed herein.
